| Summary: | Lycoriella piristylata Vilkamaa, Hippa & Heller, 2013 Literature. Lycoriella (Hemineurina) piristylata Vilkamaa, Hippa & Heller—Vilkamaa et al. (2013): 52, fig. 3 A–C. Discussion. Lycoriella piristylata was described in the former subgenus Hemineurina Frey based on the holotype and nine paratypes from Northern Finland, Norway and Sweden (Vilkamaa et al. 2013). The species was provisionally placed in L. vitticollis group of Lycoriella (Hemineurina) but because it has a sensory pit on the first palpal segment, Lycoriella piristylata belongs—in spite of the completely reduced whiplash seta on the medial side of the gonostylus—to the genus Lycoriella Frey s. str. sensu Menzel & Mohrig (2000: 380). Furthermore, the species has a bow-like bordered fore tibial organ, lacks spinose setae on the fore tibia, the tarsal claws are without teeth, the basal portion of antennal flagellomeres have long and appressed sensilla, the gonocoxae are long, ventrobasally separated in a v-shape, and the tegmen is membraneous and broadly roundish. Basoventrally in the intergonocoxal area—contrary to the original description by Vilkamaa et al. (2013: p. 53, fig. 3 A)—there is no medial lobe. At that place on the medial margin there are at most a few setae, as, for example, in L. lundstromi (Frey, 1948) and L. vanderwieli (Schmitz, 1920). Phylogeny and classification The molecular phylogeny by Shin et al. (2013) challenged the monophyly of Lycoriella s. str. + (Hemineurina + Coelostylina) (only the L. inflata group was included in the ingroup of their analysis) suggested by Menzel & Mohrig (2000) on the morphological evidence. Shin et al. (2013) suggested that Hemineurina and Lycoriella s. str. are not closely related, as they appeared in different main clades in the phylogenetic tree. The morphological characters uniting Lycoriella s. str. and Hemineurina are indeed few: the presence of the whiplash seta and the pale and weak body setosity. Coelostylina Tuomikoski, 1960 (preocc.) is a junior homonym of Coelostylina Kittl, ... |
