Pilargis de Saint‐Joseph, 1899 includes seven species and one subspecies: P. berkeleyae Monro, 1933 Monro, C. C. A. 1933.

Two species (P. verrucosa and P. berkeleyae) have been recorded from widespread localities. However, no comparison with type material has been done, and there might be some different forms under the same name. We have reviewed all the available type material in order to clarify the taxonomy of this group. A critical analysis of morphological features and a standardization of their structure and variability have been attempted. Six species are redescribed, one species is characterized after published accounts, and one subspecies is elevated to species. Four are described as new: Pilargis angeli n. sp., P. cholae n. sp., P. rozbaczyloi n. sp., and P. wolfi n. sp. Three others based on damaged material are briefly characterized. A key for Pilargis species is included.

A new feather mite genus of the family Psoroptoididae (Acari: Analgoidea) from cassowaries

A new feather mite genus Hexacaudalges gen. n. (Psoroptoididae: Psoroptoidinae) is established based on the type species Megninia casuaricola Proctor, 2001 Proctor, H. C. 2001. Megninia casuaricola sp. n. (Acari: Analgidae), the first feather mite from a cassowary (Aves: Struthioniformes: Casuariidae).. Australian Journal of Entomology, 40: 335–341.

Morphological peculiarities of this genus, its taxonomic position within the family Psoroptoididae and possible origin are discussed. We also present a clarification of setal nomenclature for this family of mites.     

Stegana castanea species group (Diptera,Drosophilidae) from the Oriental region

The Stegana castanea species group is established as a morphological group within the subgenus Steganina, based on two known and six new species from the Oriental region: Stegana (Steganina) bacilla Chen and Aotsuka, 2004 Chen, HW and Aotsuka, T. 2004.

Four species of Caligus Müller, 1785 (Copepoda,Siphonostomatoida, Caligidae) parasitic on marine fishes of Taiwan

Four species of Caligus, with two new species, are reported from five species of marine fishes of Taiwan. They are: Caligus arii Bassett‐Smith, 1898 Bassett‐Smith, P. W. 1898. Further new parasitic copepods found on fish in the Indo‐tropical region.. Annals and Magazine of Natural History (Series 7), 2: 77–98.

Journal of the University of Bombay, 25: 16–22.  [Google Scholar] on the body surface of Dasyatis navarrae (Steindachner), Caligus dactylus n. sp. on the gill filaments of Dactyloptera peterseni (Nyström), and Caligus lutjani n. sp. in the oral/gill cavities of Lutjanus argentimaculaltus (Forsskål) and Lutjanus bohar (Forsskål). Both C. arii and C. dasyaticus are reported for the first time from Taiwan. Caligus dactylus differs from its congeners by the possession of the following combination of features: large myxal process on the maxilliped; a pair of parallel tines on the sternal furca with truncate tip; simple elements (without accessory process) at the tip of leg 1 exopod; and an armature formula of I‐0; I,III on leg 4. Caligus lutjani is distinguished by carrying a two‐segmented abdomen; a pair of diverged tines on the sternal furca with acute tip; an accessory process on the middle two of the terminal four elements on the exopod of leg 1; and a bipectinate, spiniform process on the exopod of leg 4 at the insertion of each of the five outer spines.     

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.

Heteromysoides (Crustacea: Mysidacea: Heteromysini) from a submarine cave on Grand Cayman,the Caribbean Sea: descriptions of a new and a rare species

During a recent biological investigation of submarine caves of Grand Cayman, the Caribbean Sea, two species of Heteromysoides were collected. One species, referred to Heteromysoides spongicola B?cescu, 1968 Baˇcescu, M, 1968. Heteromysini nouveaux des eaux cubaines: trois espèces nouvelles de Heteromysis et Heteromysoides spongicola n. g. n. sp., Revue Roumaine de Biologie, Zoologie 13 (1968), pp. 221–237. [Google Scholar], is known only by the type specimens; therefore, this discovery marks the second record of occurrence and a new habitat record for the species. The other species is considered new and is described as H. stenoura, a 10th species of the genus. The new species closely resembles H. simplex Hanamura and Kase, 2001 Hanamura, Y, and Kase, T, 2001. A new species of Heteromysoides (Mysidacea: Mysidae) from submarine caves of Okinawa, southwestern Japan, with a key to the world species, Crustacean Research 30 (2001), pp. 65–71.[Crossref] , [Google Scholar], known from the submarine caves of Okinawa, north-western Pacific, in the possession of a spiniform process on the eyes and a simple termination to the third thoracic endopod. However, the new species can be readily distinguished from the Pacific congener by a distally narrow telson and a more developed cornea in the eyes.     

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.
