A new giant species of the subfamily Rhynchoproctinae with strikingly bi-coloured, red-yellow legs contrasting with a black body is described: Alienostreptus bicoloripes sp. nov. from Vietnam. The new species is assigned to the genus Alienostreptus Pimvichai, Enghoff & Panha, 2010 hitherto comprising one species, A. alienus (Attems, 1936), and differing from other rhynchoproctine genera by having the femoral spine duplicated. Species of this genus share three synapomorphic characters of the subfamily, viz (1) anterior coxal fold forms deep concavity in posterior view, (2) posterior coxal fold very low, and (3) posterior coxal fold with mesal flap. A superficially very similar colourful species from Borneo, also with bi-coloured legs but clearly not belonging to Alienostreptus due to the position of ventral soft pads on male legs, is documented based on photographs.
Ten species of Campodorus Förster, 1869 are reported from China and five species are new to science: C. albilineatus Sheng, Sun & Li sp. nov. from Guangxi Zhuang Autonomous Region in the Oriental part of China, C. punctatus Sheng, Sun & Li sp. nov. and C. rasilis Sheng, Sun & Li sp. nov. from Beijing, C. shandongicus Sheng, Sun & Li sp. nov. from Shandong Province and C. truncatus Sheng, Sun & Li, sp. nov. from Liaoning Province. Three species, C. ciliatus (Holmgren, 1857) and C. dauricus Kasparyan, 2005 collected from Liaoning Province and Mesoleius faciator Kasparyan, 2001 from Beijing, are new records for China. A key to species of Campodorus and a related genus known in China is provided.
Microporella Hincks, 1877 is one of the most diverse genera of cheilostome bryozoans, containing more than 150 named species. Distributed globally since the early Miocene, the majority of species of Microporella have sheet-like colonies encrusting hard and / or ephemeral substrates, while a limited number of species have erect bifoliate colonies starting from an encrusting base. Herein, the four nominal species of erect bifoliate Microporella (M. bifoliata, M. hastigera, M. hyadesi and M. ordo) are revised, and one new Pliocene (M. tanyae sp. nov.) and three new Recent species (M. ordoides sp. nov., M. lingulata sp. nov. and M. modesta sp. nov.) are formally described. Furthermore, the lectotype and paralectotypes were designated for M. bifoliata and M. hastigera. An additional Recent species, Microporella sp. 1, is also described and illustrated but left in open nomenclature owing to the absence of ovicells in the single available fragment. Although the molecular phylogeny of Microporella has yet to be resolved, the diversity of character states present among the erect bifoliate species described here suggests that this colony growth-form is not monophyletic but has evolved on multiple occasions.
Recent samplings in cavities of the Iberian Peninsula led to the discovery of a new millipede species of the order Callipodida in one cave in the region of El Bierzo (León, Spain): Lusitanipus xanin sp. nov. In additional samplings (near that cave), more specimens of this new species were discovered in surface habitats. The species has various distinctive characteristics, such as its green colour, but the morphology of the gonopod has several similarities with that of Lusitanipus alternans (Verhoeff, 1893), indicating a close relationship between them. The diagnosis of the genus Lusitanipus Mauriès, 1978 has to be changed to accommodate the new species. The presence of crests in two different sizes is no longer a diagnostic character of the genus Lusitanipus, but of the species L. alternans. Lusitanipus xanin sp. nov. is the fourth species of the order Callipodida for the Iberian Peninsula, and the second species for the genus. Lusitanipus xanin sp. nov. seems to be an epigean but troglophile species.
Two new congeneric species endemic to Fiji are introduced: Nesobasis martina sp. nov. [holotype female, Viti Levu Is] and N. monika sp. nov. [holotype male, Taveuni Is]. The species are placed in the comosa- and erythrops-groups respectively (grouping following Donnelly 1990). Diagnostic features are proposed, but not discussed. Further discussion is left for an ongoing revision of the genus (Donnelly & Marinov in prep. ). The new species reported here are introduced ahead of this revision in a study which was made possible due to the International Dragonfly Fund (IDF) offering the opportunity to pick a new species' name for a donation.
