VICTORIA: 1 male (SL 10.8 mm), off Cape Everard, 119 m, Aug 1948, coil. W. French, NMV 110990. Diagnosis. Intermediate gills. Shield (Fig. 24a) as broad as long; dorsal surface weakly calcified medially, and with low blister-like tubercles; rostrum broadly rounded, with short mid-dorsal ridge; anterior margins weakly concave; lateral projections subtriangular, with terminal spine; posterior margin broadly rounded. Ocular peduncles more than half length of shield, with dorsal longitudinal row of setae. Cornea slightly dilated. Ocular acicles subtriangular, terminating in strong spine usually directed anteromesially. Sternite of 3rd maxillipeds with small spine on each side of midline. Epistome with strong, straight spine. Antennular peduncle long, slender, exceeding distal margin of corneae by nearly entire length of ultimate segment. Antennal peduncle (Fig. 24b) exceeding distal margin of cornea by at most 0.20 length of 5th segment; 3rd segment with strong ventromesial distal spine; acicles curved outward (in dorsal view), not exceeding distal margin of corneae, and armed mesially with 4 to 7 strong spines; flagellum long, reaching to or slightly exceeding extended right cheliped, articles with very short setae interspersed with long setae every 5 to 15 articles. Chelipeds markedly dissimilar, glabrous or at most with scattered short setae, carpi and chelae usually iridescent dorsally. Right cheliped (Fig. l4d,e) with small tubercles or spines on dorsal surfaces of carpus and chela (tubercles or spines decreasing in size and number with increased size of individuals); fingers curved ventromesially; palm with dorsolateral margin well delimited by row of blunt to sharp spines, mesial face rounded. Left cheliped (Fig. 24c) with dorsolateral face of carpus frequently weakly calcified; chela with dorsomesial row of few small spines; carpus with irregular row of small spines dorsally. Ambulatory legs (Fig. 24 d-f) reaching to tip of right cheliped, unarmed except for dorsodistal spine on carpus; dactyls approximately 1.8 times as long as propodus, each with ventromesial row of about 8 to 14 corneous spines. Anterior lobe of sternite of 3rd pereopods unarmed, or rarely with small blunt marginal spine. Fourth pereopod (Fig. 24g,h) with dactyl terminating in sharp corneous claw (longer and more slender in females than in males); propodal rasp consisting of 1 row of rounded scales. Uropods and telson markedly asymmetrical; telson (Fig. 24k) with weak transverse suture; dorsal surface usually with low, blister-like tubercles; posterior lobes separated by narrow cleft, terminal margin of lobes armed with numerous corneous spines (often strongly curved on left lobe). Male 1st gonopods (Fig. 241) each with concave distal lobe; 2nd gonopods (Fig. 24j) each with distal segment setose on distomesial face, and row of short bristle-like setae on lateral margin. Females occasionally with paired 1st pleopods; with vestigial 2nd right pleopod. Distribution. Western Pacific: Japan; China Sea; and Australia. Depth: 40 to 695 m. Colour. In fresh specimens, general colour orange or reddish (in preservative, colour fades to cream white except on chelipeds where patterns remain for considerable time). Chelipeds with fingers cream white; dorsal surface of carpus and chela orange or reddish, iridescent, fading to white laterally. Walking legs orange or reddish, fading to cream white towards the dactyls. Carpi of chelipeds and walking legs each with dark red band proximally. Merus of right cheliped with dark red stripe dorsomesially. Carapace and chelae with small, scattered red spots. Affinities. Paragiopagurus diogenes most closely resembles two species recently described from French Polynesia (as Sympagurus), P bougainvillei (Lemaitre, 1994), and P wallisi (Lemaitre, 1994). Paragiopagurus diogenes can be separated readily from those two species by differences in coloration, or in the absence of colour, by the weaker armature of the carpus and chela of the right cheliped in P diogenes than in the two from French Polynesia. Remarks. Whitelegge (1900: 177), in his description of Sympagurus diogenes, listed an "adult female" and a "young male" (AM G2379, G2380). He included measurements for one specimen without indicating sex; obviously they correspond to the female which is larger in size. While examining type material deposited in the Australian Museum, however, an additional male specimen was found labelled "co-type" (dry, and catalogued under the same number as the other male, AM G2380). This dry male specimen was collected at the same date and locality as the male listed by Whitelegge (see Springthorpe & Lowry, 1994). In order to avoid any potential confusion, and considering that Whitelegge's species is the type of Paragiopagurus n.gen., a lectotype is herein selected for Whitelegge's taxon. The female used by Whitelegge (1900) has paired 1st pleopods. It is not uncommon for this condition to occur in some female individuals of other parapagurid species, such as Sympagurus pictus Smith, 1883, and S. dimorphus (see Lemaitre, 1989). Whitelegge's (1900: pI. 34, fig. 3) photograph was evidently reversed during the printing process as it shows the larger cheliped on the left side rather than on the right. Hale (1941) considered Whitelegge's (1900) Sympagurus diogenes (= Paragiopagurus diogenes [Whitelegge, 1900]) a subspecies of S. arcuatus, based on the dense pilosity of the right cheliped that he (Hale) observed in specimens from Tasmania and Macquarie Island. The surface of the chelipeds in Paragiopagurus diogenes is glabrous, at most with only scattered setae. Although Hale did not give any other information on his specimens, and they have not been available for examination, it is clear that they are not of P diogenes, and instead represent some other undetermined species. This species is among the most common parapagurids in Australian waters, and is frequently found in depths less than 100 m. : Published as part of Lemaitre, R., 1996, Hermit crabs of the family Parapaguridae (Crustacea: Decapoda: Anomura) from Australia: species of Strobopagurus Lemaitre, 1989, Sympagurus Smith, 1883 and two new genera., pp. 163-221 in Records of the Australian Museum 48 (2) on pages 208-211, DOI: 10.3853/j.0067-1975.48.1996.286, http://zenodo.org/record/4654966 : {"references": ["Whitelegge, T., 1900.
