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.

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.     

Revision of Pilargis de Saint‐Joseph, 1899 (Annelida,Polychaeta, Pilargidae)

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.     

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.     

Description of a new fireworm,Eurythoe turcica sp. nov. (Polychaeta: Amphinomidae), from the Levantine coast of Turkey (eastern Mediterranean), with re‐descriptions of Eurythoe parvecarunculata Horst and Amphinome djiboutiensis Gravier based on type material

The present study describes a new fireworm belonging to the genus Eurythoe, E. turcica sp. nov., collected from Iskenderun Bay and its vicinity (Levantine Sea, Turkey), and re‐describes the closely related species E. parvecarunculata Horst, 1912 Horst, R. 1912. Polychaeta errantia of the Siboga Expedition. Part 1, Amphinomidae..

Contribution à l’étude des annélides polychètes de la Mer Rouge.. Nouv Arch Mus., 3(4): 147–268.  [Google Scholar], based on the type material. The new species is mainly characterized by having a rounded and short caruncle occupying only chaetiger 1, and dendritically branched branchiae from chaetiger 3 to the end of body. Morphological features of E. turcica are closely similar to those of E. parvecarunculata but the former species lacks the serrated capillary chaeta with a long spur on the notopodia of the median parapodia. The present study also shows that A. djiboutiensis and E. parvecarunculata, which were previously considered synonymous, are distinct species.     

Establishment of a new subfamily for Shenius anomalus (Shen, 1935) (Crustacea: Decapoda: Brachyura: Dotillidae)

Shenius anomalus (Shen, 1935 Shen, CJ. 1935. On some new and rare crabs of the families Pinnotheridae, Grapsidae and Ocypodidae from China. Chin J Zool., 1: 19–40. 15 figures [Google Scholar]) has previously been assigned to the Macrophthalmidae Dana, 1851, and the Camptandriidae Stimpson, 1858 Serène, R. 1974. Note on the genera and species of the Camptandriinae Stimpson, 1858 (Decapoda, Brachyura: Ocypodidae). Treubia, 28(3): 59–117.  [Google Scholar]. A close examination of adult and first stage zoeal morphology confirms some previous suggestions that S. anomalus is actually an anomalous member of the Dotillidae Stimpson, 1858 Serène, R. 1974. Note on the genera and species of the Camptandriinae Stimpson, 1858 (Decapoda, Brachyura: Ocypodidae). Treubia, 28(3): 59–117.  [Google Scholar]. However, because a number of distinctive features distinguish it from all other dotillid genera a new subfamily Sheniinae is established.     

On the morphology and geographical distribution of some problematic South Palearctic Cyclops (Copepoda: Cyclopidae)

Females and males of two South Palearctic Cyclops, C. ankyrae Mann, 1940 Mann, A. K. 1940. Über pelagische Copepoden türkischer Seen (mit Berücksichtigung des übrigen Planktons).. Internat Rev Hydrobiol., 40: 1–87.  [Google Scholar] and C. abyssorum divergens Lindberg, 1936 Lindberg, K. 1936. Notes sur des Cyclopides (Crustacés Copépodes) de l'Iran.. Bull Mus R Hist Nat Belg., 12(17): 1–26.  [Google Scholar] are redescribed, and their taxonomic relationships are discussed. Cyclops ankyrae can be distinguished from congeners by the spine formula of the terminal exopodal segments (2433), distinct anal operculum, bare proctodeum, presence of a longitudinal row of large spinules near the palp on the frontal surface of the mandibular coxopodite, spinule ornamentation of the maxilliped coxopodite, presence of hairs on the caudal surface of P3–P4 couplers, and lack of large spinules on the frontal surface of the P1 basipodite. Cyclops abyssorum divergens differs from C. abyssorum s. str. in the relatively short inner median caudal seta, reduced spinule ornamentation on the caudal surface of P4 coxopodite, and presence of large spinules on the maxillular palp. Cyclops singularis Einsle, 1996 is synonymized here with C. a. divergens Lindberg, 1936 Lindberg, K. 1936. Notes sur des Cyclopides (Crustacés Copépodes) de l'Iran.. Bull Mus R Hist Nat Belg., 12(17): 1–26.  [Google Scholar]. The geographic distribution of C. a. divergens is revised.     

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.
