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. Four species are first recorded from this region, D. richardsonae Stebbing, 1910 Stebbing, T. R. R. 1910. Isopod from the Indian Ocean and British East Africa..

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.     

The freshwater shrimps of the genera Caridina and Parisia from karst caves of Sulawesi Selatan,Indonesia, with descriptions of three new species (Crustacea: Decapoda: Caridea: Atyidae)

Six species of Caridina were present, of which two are new to science and one is new to Sulawesi, as well as one new species of Parisia. Types of Caridina pareparensis De Man, 1892 De Man, J.

Caridina pareparensis parvidentata is here regarded as a distinct species. The new taxa are described, figured and compared with congeners.     

Zerconid mites (Acari: Mesostigamata: Zerconidae) from Croatia with description of four new species

This paper contributes to the knowledge of the family Zerconidae, describing material collected from several locations in Croatia. Seventeen species are listed, four of them (Prozercon martae sp. nov., Zercon danyii sp. nov., Zercon laczii sp. nov. and Zercon lanceolatus sp. nov.) proved to be new to science, a further eight species (Zercon arcuatus Trägårdh, 1931 Trägårdh, I. 1931.

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.

[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.

In comparison with Flabelligera Sars, 1829 Sars, M. 1829.

Four species are described and presented as new combinations, and three others were previously undescribed; thus the species included are F. papillosa (Essenberg, 1922 Essenberg, C. E. 1922.
