Redefinition of the parastenocaridid genus Proserpinicaris (Copepoda: Harpacticoida), with description of three new species from Korea

Proserpinicaris young sp. nov., Proserpinicaris wangpi sp. nov. and Proserpinicaris imjin sp. nov. are described from subterranean waters of South Korea. They are short-range endemics, allopatric in distribution and closely related to each other, and to two other Far Eastern congeners. Distinguishing features are limited to the general habitus shape, proportions of the caudal rami and degree of sexual dimorphism. The genus Proserpinicaris Jakobi, 1972 Jakobi, H. 1972. Trends (Enp.P4 Mänchen) innerhalb der Parastenocarididen (Copepoda Harpacticoidea). Crustaceana, 22: 127–146. [Crossref] , [Google Scholar], as redefined here, is Palaearctic in distribution, with the centre of diversity in southern Europe, and 20 valid members, all of which share a large hyaline spiniform structure on the male fourth leg basis as a synapomorphy. A key to species is provided. Genera Niponnicaris Jakobi, 1972 Jakobi, H. 1972. Trends (Enp.P4 Mänchen) innerhalb der Parastenocarididen (Copepoda Harpacticoidea). Crustaceana, 22: 127–146.

[Crossref] , [Google Scholar] are described. Dorylaimellus shamimi sp. nov. has body 1.1–1.2 mm, offset lip region, odontostyle 7–8 μm, pharyngeal expansion 35–43%, longitudinal vulva, amphidelphic gonad and conoid ventrally arcuate tail. Dorylaimellus parindicus sp. nov. has body 1.2–1.5 mm, distinct ventral body pores, lip region offset, odontostyle thick walled, 5–6 μm, odontophore with poorly developed flanges, pharyngeal expansion 38–45%, longitudinal vulva, amphidelphic gonad and short conoid tail.

Dorylaimellus khasianus sp. nov. has body 1.2–1.4 mm; offset lip region; odontostyle 7 μm; odontophore with well developed flanges; pharyngeal expansion 31–35%; longitudinal vulva; amphidelphic gonad and elongate-conoid tail.

Designation of Thouarella abies Broch, 1965 as the type species of the subgenus Fannyella (Scyphogorgia) Cairns and Bayer, 2009, and description of a new genus for Stenella (Dasystenella) liouvillei Gravier, 1913 (Octocorallia: Primnoidae)

Recently the two Antarctic gorgonian species Stenella (Dasystenella) liouvillei Gravier, 1913 Gravier, CH. 1913. Seconde Expédition Antarctique Française (1908–1910). Alcyonaires (2° note préliminaire). Bull Mus Nat Hist Nat. Paris, 19: 589–593.  [Google Scholar] and Thouarella abies Broch, 1965 Broch, H. 1965. Some octocorals from Antarctic Waters. Scientific Results of the “Brategg” Expedition, 1947–48. Christensens Hvalfangstmus i Sandejford Publ., 26: 19–38.  [Google Scholar] were synonymized and considered as Fannyella (Scyphogorgia) liouvillei. The re-examination of the type material of both species and newly collected specimens demonstrate that this synonym can no longer be considered valid. In the present study we propose, following the International Code of Zoological Nomenclature, to change the current type species of the subgenus Scyphogorgia, Stenella liouvillei, to Thouarella abies, the new combination being Fannyella (Scyphogorgia) abies. Furthermore we propose a new genus, Scopaegorgia, to accommodate Stenella liouvillei. Both species are completely re-described from the type material and the abundant specimens collected during some recent Antarctic cruises.

Earthworms from Argentinean Patagonia with description of two remarkable new species (Oligochaeta: Acanthodrilidae,Lumbricidae and Megascolecidae)

A new deep-sea benthopelagic chaetognath of the genus Bathyspadella (Chaetognatha) with ecological and molecular phylogenetic remarks

A new chaetognath, Bathyspadella oxydentata, collected from Sagami Bay, central Japan, is described. The new species was collected from deep-sea benthopelagic habitat and is distinguished from the closely related species Bathyspadella edentata Tokioka, 1939 Tokioka, T. 1939. Three new chaetognaths from Japanese waters. Mem Imp Mar Obs., 7: 129–140.  [Google Scholar] by the presence of teeth. The phylogenetic position of the new species was examined by molecular genetic analysis using partial sequences of 18S rRNA and 16S rRNA. Although B. oxydentata shares several morphological features with both Spadellidae and Eukrohnidae, the molecular phylogeny indicates that the new species is closely related to Heterokrohnidae species.     

Gonopod segmentation and the Australian centipede Prionopodella (Chilopoda): testing a basal position in the Scutigeromorpha

The monotypic centipede genus Prionopodella Verhoeff, 1925 Verhoeff, K. W. 1925. Results of Dr. E. Mjöberg's Swedish scientific expeditions to Australia 1910–1913. 39. Chilopoda.. Arkiv för Zoologi, 26A: 1–62.  [Google Scholar] has until now been known only from the types of its type species, collected in Queensland, Australia, nearly a century ago. The female gonopods of Prionopodella were described as having a uniquely tripartite structure, viewed as primitive relative to the bipartite gonopod of all other Scutigeromorpha. An articulation in the syntelopodite is present in one syntype, but new specimens from central eastern Queensland show an, at most, incompletely jointed or entirely unjointed syntelopodite, as in other scutigeromorphs. Cladistic analysis of morphological characters including Prionopodella and the likewise monotypic Australian genus Prothereua Verhoeff, 1925 Verhoeff, K. W. 1925. Results of Dr. E. Mjöberg's Swedish scientific expeditions to Australia 1910–1913. 39. Chilopoda.. Arkiv för Zoologi, 26A: 1–62.  [Google Scholar], shows Prionopodella to nest within Thereuoneminae, allied to other Asian/Australian genera, rather than in a basal position within Scutigeromorpha as is implied by Verhoeff's theory about primitive gonopod structure.     

New species and rediagnosis of Coecobrya (Collembola: Entomobryidae), with a key to the species of the genus

The history of Coecobrya is traced and the genus is redefined. Two new species are described and one known species is redescribed in this paper: Coecobrya lanna sp. nov., Coecobrya tukmeas sp. nov. and Coecobrya aokii (Yoshii, 1995 Yoshii, R. 1995. Notes on Collembola of Vanuatu. Acta Zool Asiae-Orient., 3: 43–50.  [Google Scholar]). Additional details are provided for three other species Coecobrya guanophila Deharveng, 1990 Deharveng, L. 1990.

A key to the world species of Coecobrya is given.     

Four new records and a new species of Dactylokepon Stebbing, 1910 (Epicaridea: Bopyridae: Ioninae) from Chinese waters

Five species of the parasitic isopod genus Dactylokepon are described from brachyuran crabs and a scyllarid shrimp collected in Chinese waters.

In addition, one species is new to science, D. barbuladigitus n. sp. infesting Liagore rubromaculata (De Haan). Six brachyuran crabs are reported for the first time as hosts of bopyrids. The new species is distinguished from other species of Dactylokepon in having a prominent trifid frontal lamina and a distinct digitate barbula.
