| Summary: | Microthalestris Sars, 1905 Various authors have reported on what they individually regard as Parastenhelia spinosa or varieties/species sharing some of its morphological characteristics, but recognise a wide range of variation in features such as segmentation of the female antennule, modification of the caudal ramus setae (particularly V), setation of the antennary exopod and endopod, relative proportions of P1 rami and form of their terminal elements, armature formulae of P2–P4, shape and armature of ♀ P5 exopod, and segmentation of ♂ P5 exopod. The magnitude of this variability, or the identity of differences which might represent true genetic discontinuity (and thus distinct species), is in many cases impossible to determine due to the inaccurate and/or incomplete descriptions and illustrations [especially the original description by Fischer (1860)] which have accompanied many published reports. The currently accepted concept of P. spinosa being a highly variable, cosmopolitan taxon has grown over time since 1860 by the gradual accumulation of differences observed in what were wrongly assumed to be geographically isolated populations of the same species. The historical review presented below aims at (a) pointing out some important misconceptions in the taxonomy of the species, (b) assigning distinct specific status to some of its radically divergent “populations”, and (c) formulating a working hypothesis and baseline for future comparisons and revisionary work. Parastenhelia spinosa was first described as Harpacticus spinosus by Fischer [1860: 665–666, Table XXI (figures 51–53), XXII (figure 66)] from the island of Madeira [Lang (1948: 589) stated incorrectly that Fischer did not disclose the type locality] but the description is severely lacking in any real detail (8-segmented antennule, ovate female P5 with four spines on exopod and baseoendopod, caudal ramus seta V swollen at base) and only his illustration of the P1 provides the barest minimum to identify it as a member of the Parastenheliidae.The inaccuracies expressed in the few poorly rendered drawings (maxilliped, P1, female P5, caudal rami) and the lack of the male make the description virtually useless for comparative purposes. Harpacticus spinosus is placed in Microthalestris solely on account of its elongate P1 exp-2 but cannot be treated as anything more than a species inquirenda in this genus. Had Lang’s (1948) fixation of H. spinosus as the type of Parastenhelia been valid, this would have threatened stability and universality in the application of the name of the type species since its taxonomic identity cannot be determined from its name-bearing type. Although Lang (1936a: 21) considered the possibility that Fischer’s (1860) species was conspecific with Parastenhelia forficula var. littoralis (sensu Sars 1911) he recommended to set it aside on the grounds that it cannot be identified with any degree of confidence. Unfortunately, he changed his opinion by not only reinstating it as a valid species but also by illegitimately fixing it as the type of the genus (Lang 1944: 13; 1948: 586–588). Claus (1863: 131–132, Plate XVII, figs 7–11) described Thalestris forficula Claus, 1863 as one of ten species assigned to his new genus Thalestris Claus, 1862 (type species by subsequent designation: Thalestris longimana Claus, 1863). The author reluctantly included H. spinosus in the genus as well as two other Harpacticus species previously described by Fischer (1860). His description of T. forficula , based on material from Messina (Sicily), included illustrations of the antennule of both sexes, P1, caudal rami and the female genital field.The most significant information that can be extracted from Claus’s (1863) concise description is the 8-segmented condition of the female antennule, the presence of an apophysis on the male P3 endopod, the modified caudal seta (V) displaying a basal swelling, and the length of the relatively short inner seta on P1 enp-1 which extends only to about 40% of the segment length. No information was given about the armature of P2–P 5 in both sexes, or the segmentation of the male P5 exopod. ......continued on the next page ......continued on the next page 1 The absence of the inner seta on exp-2 requires confirmation. 2 2-segmented in ♂ (1.221); Thompson & Scott (1903) do not illustrate the inner seta on ♂ enp-1 in Pa. hornelli which is possibly an observational error (but see Apostolov 1973: Fig. 9–9). 3 The short, fine, distal inner seta on exp-3 is probably overlooked. 4 0.221 in ♂. 5 1.1.02 + apo in ♂. 6 Based on Wells & Rao’s (1987) redescription of Pa. hornelli from Middle and South Andaman Islands. The original description of Pa. similis by Thompson & Scott (1903) lacks information on P2–P3 and figures P4 exp-3 with only two inner setae (the short distal one being overlooked). 7 Wells & Rao (1987) claim that exp-2 is unarmed and has only a long spinule. This observation is probably correct since in all other species with a 3-segmented exopod the inner seta arises from the distal corner and not from halfway along the inner margin. 8 2-segmented in ♂ (0.121). 9 0.1.02 + apo in ♂. 10 Note that the armature formulae given by Wells & Rao (1987: Table 4) for the exopod of P3 and both rami of P4 are incorrect. 11 Both sexes were figured (Vervoort 1964: Figs 68c, 69a) without an inner seta on exp-2 which is probably an oversight. The same error probably applies to Sewell’s (1940) descriptions of Pa. littoralis (Text-Fig. 26–G) and Pa. littoralis f. scotti (Text-Fig. 28–D). 12 Armature pattern of enp-3 121 in ♂. 13 The vestigial seta was probably overlooked in the descriptions by Fischer (1860), Car (1884), Scott (1894a), Sewell (1940), Apostolov (1973) and Noodt (1964). 14 Armature formula of P1 and P4 based on Apostolov (1973) who also reported a different armature for the ♀ P5 exopod (six setae). 15 1.1.12 + apo in ♂ P3 endopod. 16 Brady’s (1910) description is grossly inadequate and incomplete; the setal counts presented here for P2 and P5 baseoendopod are based on his illustrations (Textfig. VIII: Figs 3–4) and are most certainly incorrect, as well as his claim that the endopodal armature pattern for P2–P4 is [1.1.120]. 17 Based on Lang’s (1936a: Fig. 37) supplementary description (as Pa. gracilis ). 18 Pallares (1982: 10) erroneously stated that P3–P4 exp-3 display a [333] pattern in the male; probably not having consulted Pallares’s drawings of the male, Mielke (1990: 166) accepted this as an additional difference between the type population and his material collected from Bahía Lapataia near Ushuaia (Argentina). 19 Armature pattern of enp-3 021 in ♂. 20 0.1.12 + apo in ♂. 21 The single ♀ observed by Mielke (1974: 20) showed an aberrant setal pattern on one side of P2 enp-2 (with two inner setae) and P4 exp-3 (with inner seta). 22 There is confusion over the exact number of elements on the exopod. Pallares (1963) states that there are three outer, one inner and two apical elements but in a subsequent account (Pallares 1968: 65) explicitly states that there are seven without going into detail about their position. We have adopted Pallares’s original observation pending reexamination of new material. 23 Lang’s (1936b: 24) only female displayed the atypical 121 pattern on enp-3. 24 Mielke (1990) recorded a high degree of variability in the armature of P2–P4. Some specimens displayed (a) an inner seta on P2–P3 exp-2, (b) only one (instead of two) inner seta on P3 exp-3, (c) two (instead of one) inner setae on P4 exp-3, (d) two (instead of one) inner setae on P3–P4 enp-3, and/or (e) only two (instead of three) outer spines on P4 exp-3. One male lacked the inner seta on P4 enp-2. 25 According to Wells (2007: 596) the original report of three inner setae on P2 exp-3 is wrong. 26 The endopodal armature pattern differs from Mielke’s (1994a: 257) in two aspects; the apical spiniform element on enp-3 is here considered as the homologue of the outer spine in other genera, and the two minute and fine setae originating from the inner corner of enp-3 are included in the formulae. 27 Inner seta minuscule (Mielke 1994a: Fig. 4C). 28 2-segmented in ♂ (1.321). 29 1.1. 321 in ♂; Kunz (1975) did not illustrate the ♀ condition but listed the armature formula of P3 endopod as 1.1. 221 in his Table 5; Gee (2006) re-examined the type material and noted that the armature formula is as in F. anglica . 30 2-segmented in ♂ (1.121). 31 1.1.021 in ♂. 32 Willey (1935) reported some specimens with a 3-segmented endopod in the ♀ (1.1.221). 33 P3 endopod ♂ and P 5 ♂ based on Vervoort’s (1964) description of Pa. spinosa [partim]. According to Sewell (1940: Text-fig. 27H) P2 exp-1 lacks an inner seta but Vervoort shows a small inner element which is included in the armature formula here. 34 Scott (1894a: Plate 12, Fig. 39) most likely overlooked the short inner seta on exp-3. 35 Sewell (1940: 196) claims the proximal inner seta was overlooked in Scott’s (1894a) description, bringing the total to five. 36 1.221 in ♂. In a paper written in old Danish and completely lacking in illustrations, Boeck (1865: 266–267) described a new species, Thalestris karmensis Boeck, 1865, based on specimens collected from Karmøy in Norway; this species fell into oblivion until it was discussed by Sars (1905 – see below). In a similar contribution, Boeck (1873: 56) provided a short unillustrated text description of Dactylopus longipes Boeck, 1873, obtained from 29 m depth in the Oslofjord in Norway. His female specimens were characterized by a 9-segmented antennule, a long and slender P1 exopod which is shorter than enp-1, a 2-segmented P1 endopod with a very long enp-1 which bears a seta in the proximal quarter of the inner margin, and a P5 exopod with eight elements. Based on this short description Lang (1936a: 31) would later synonymize D. longipes with Thalestris forficula which he had previously placed in Parastenhelia (Lang 1934: 24). Thomson’s (1883: 104–105; Plate X, Figs 16–21) material of Thalestris forficula from Otago Harbour in New Zealand agrees with the description of Claus (1863) in the 8-segmented condition of the female antennule and the basally inflated setae V on the caudal ramus but differs in size (1,000 vs 800 μm) and the morphology of P1. The female P5 bears six and five setae on the exopod and endopodal lobe, respectively. Lang (1934: 25) lists Thomson’s record but does not appear to question its identity. In later accounts he accepts it as a record of either Parastenhelia forficula var. littoralis (Lang 1936a: 52) or P. spinosa (Lang 1948: 588). Car (1884: 248–249, Plate XVIII, Figs 1 –8) provided an illustrated description of a new species, Thalestris pectinimana Car, 1884, based on a single ovigerous female collected in the vicinity of Trieste, northeastern Italy. The author did not compare T. pectinimana with other congeners nor did he present a justification for its recognition as a distinct species. Illustrations were provided for the female in lateral aspect, antennule, antenna, maxilliped, distal segments of the P1 rami and P5. The species is characterized by the 8-segmented antennule, the large P5 with seven setae on the foliaceous exopod and five elements on the endopodal lobe, and the presence of distinct pectinate spines on the terminal segments of P1 exopod and endopod. No information was given on the armature of P2–P4. The species has not been recorded again since its original description. Pesta (1920: 590) listed it as a junior subjective synonym of Phyllothalestris mysis (Claus, 1863) but this was rejected by Lang (1936a: 49) who considered it a valid species of Thalestris . Lang (1948: 497, 588) revised his previous opinion and considered T. pectinimana conspecific with Parastenhelia spinosa , more specifically (based on P5 morphology) with the form described as Microthalestris littoralis f. penicillata by Willey (1935: 82). This claim is dubious since Willey did not describe the female P5 but only stated that it displays “… the fifth foot of littoralis ”. According to Sars’s (1911: Suppl. Plate 11) description of M. littoralis the female P5 has only six setae on the exopod while T. pectinimana exhibits seven. Scott (1894a: 100–101, Plate XII, Figures 33–41) recorded a single ovigerous female of T. forficula from a shore gathering in Accra (Ghana). The specimen is similar to Claus’s (1863) material in the 8-segmented antennule and the basally swollen caudal ramus setae (V), however, is distinctly smaller (500 vs 800 μm). The most conspicuous feature is the presence of two strong pectinate claws on both P1 exp-3 and P1 enp-2. His illustration of P4 shows that it lacks the inner seta on exp-1 and has two inner setae on enp-3 (221). The female P5 has a reduced armature (if Scott’s observations are correct), displaying six setae on the exopod and only four on the endopodal lobe. The latter observation was disputed by Sewell (1940: 196) who believed that the proximal inner seta of the endopodal lobe was overlooked. Scott & Scott (1894: 142–144, Plate IX, Figs 4 –9) described Thalestris forficuloides from mud near the lowwater mark at Seafield in the vicinity of Leith, Firth of Forth, Scotland. An expanded description of the female and additional illustrations of the male were provided by Scott (1894b: 255–256, Plate X, Figures 13–25) based on specimens from the type locality (note that the mandible and maxillule were transposed in his Plate X). As the name suggests this species was considered close to T. forficula , displaying differences in the segmentation of the female antennule (9-segmented vs 8-segmented in T. forficula ), the length of the P1 endopod, and some unspecified discrepancies in the ”… proportional lengths of the other thoracic feet” (Scott & Scott 1894: 144). Sars (1905: 122) proposed a new genus Microthalestris in the Thalestridae to accommodate T. forficula as its type and only species and stated that the forms recorded by Boeck (1865) as Thalestris karmensis and by Scott & Scott (1894) as T. forficuloides , both belong to M. forficula (Claus, 1863). His redescription of the latter (Sars 1905: 123–124, Plate LXXVI) corresponds exactly to the illustrations of Scott (1894b) in the segmentation of the antennule, morphology of P1, and the basally inflated caudal ramus seta (V), however, also shows a number of important differences with T. forficuloides including (a) P3 exp-1 with inner seta instead of without, (b) P3 exp-3 with two inner setae instead of three, (c) P5 exopod ♀ comparatively longer, and (d) P5 exopod ♂ 3-segmented instead of 1-segmented. Although Sars was not specific about the total number of setae on the male P5 exopod it appears from his illustration that there are only six as opposed to the seven recorded in later descriptions. There is a hint of a short setal element among the spinular cluster on the outer margin of exp-1, however, the seta usually found in that position is typically very long ( e.g. Chislenko 1967: Fig. 45; Mielke 1974: Fig. 9D). Lang’s (1936b: 23, Fig. 52) observation of a similar condition in a male from the Øresund indicates that it is genuinely lost (or extremely reduced) rather than broken off during dissection. Although Lang (1934: 24) expressed doubts, primarily based on differences in antennulary segmentation, about the conspecificity of Sars’s (1905) Norwegian specimens of M. forficula and Claus’s (1863) type material of T. forficula , he cited the former as a synonym of the new combination Parastenhelia forficula (Claus, 1863). Sars (1911: 369–370, Supplement plate 11-1) added the new species M. littoralis Sars, 1911 to the genus which showed more or less the same distribution in Norway as M. forficula , including various localities along the south and west coasts and further northwards to the Trondhjem Fjord (Bejan). Sars (1911) only reported the female which differs from that of the type species in the more compact antennule (the number of segments was not disclosed), the longer and more slender P1, the number of exopodal setae on the P5 (six vs eight) and the normally developed seta V on the caudal ramus. Unfortunately, no information on the armature formula of P2–P4 was given which inevitably led to the incorrect assignment of various non-conspecific populations to this species. Farran (1913) observed considerable variation in body size (500–850 μm) in his material of M. littoralis from Clare Island and Blacksod Bay, Co. Mayo (Ireland) (see also Farran et al. 1915; Southern 1915) which he viewed as a possible indication of the presence of a second species. All specimens agreed with Sars’s (1905) description in the morphology of the female P5. Pesta (1920: 591–593) summarized records of Microthalestris in the Adriatic, including M. forficula in the Venice Lagoon (Grandori 1912, 1914) and M. littoralis from the Palagruža (Pelagosa) archipelago (Steuer 1912). Brian (1921: 77–80) reported M. littoralis from the Gulf of Genoa, illustrated naupliar stages I and III–V (Text figures 23–25; Plate VI, Fig. 3) and described copepodids III–V (Plate VIII, Figs 10–22). Dahms & Hicks (1996) pointed out that Brian’s naupliar illustrations in reality refer to NIV–NVI. Brian’s (1921) description reveals little information about the female except for the lateral aspect view of an ovigerous specimen (Plate III, Fig. 7), showing the presence of a single egg sac, and the ventral view of the abdomen (Plate V, Fig. 15) which shows that the caudal ramus seta V is not swollen at the base. His illustrations of the male (Plate IV, Fig. 9; Plate V, Fig. 5; Plate IX, Figs 9–14) document three characters of particular significance, (a) the presence of two penicillate spines on the antenna (already expressed in copepodid IV: his Plate VIII, Fig. 17), (b) the 3-segmented P3 endopod in the male bearing an inner seta on enp-1 and -2, in addition to the apophysis and two apical setae on enp-3, and (c) the 1-segmented condition of the male P5 exopod bearing seven setae. No information was provided on the segmentation of the female antennule or armature of the swimming legs and P5. Monard (1927) retained Microthalestris in the Thalestridae as an “insufficiently described genus” (p. 157) in his Synopsis universalis generum harpacticoidarum but placed the clo : Published as part of Huys, Rony & Mu, Fanghong, 2021, Johnwellsia, a new intertidal genus of Parastenheliidae (Copepoda, Harpacticoida) from the Taiwan Strait, China, including a review of the family and key to genera, pp. 236-318 in Zootaxa 5051 (1) on pages 256-270, DOI: 10.11646/zootaxa.5051.1.13, http://zenodo.org/record/5572417 : {"references": ["Sars, G.
