A new wolf spider species in the Pardosa monticola‐group (Araneae: Lycosidae) from Xinjiang,China

The Plateremaeoidea demonstrate highly differentiated patterns of dorsal setae on the hysterosoma because these setae are lost in protonymph and adult. Setal loss in protonymph always starts with setae of d-series, and occurs in order, continuing to the l-series and h-series. For example, Aleurodamaeus setosus (Berlese, 1883 Berlese, A. 1883. Escursione in Sicilia. Acarofauna Sicula. Ia serie. Bull Soc Entomol Ital., 15: 212–220.  [Google Scholar]) and Al. africanus Pletzen, 1963 Pletzen, R Van. 1963. Studies on South African Oribatei, II. Plateremaeidae Trägardh 1931; Genus Pedrocortesella Hammer 1961. Acarologia, 5(3): 438–442.  [Google Scholar] lose setae of d-series in protonymph, and eight pairs in adult (c-series, l-series, h ₂, h ₃), so four pairs of setae remain (h ₁, p-series).

Redia., 5: 31–91.  [Google Scholar]) also lose seta h ₂ in protonymph, and setae of c-series in adults, so six pairs of setae (h-series, p-series) remain in the former species, and four pairs (h ₁, p-series) in the latter species. Morphological characters of juveniles and adults of eight species of Plateremaeoidea are compared.     

Differentiation of external morphology of Oribatella Banks, 1895 (Acari: Oribatida: Oribatellidae), in light of the ontogeny of three species

Differentiation of external morphology of Oribatella Banks, 1895 was investigated, in light of the ontogeny of O. quadricornuta (Michael, 1880 Michael, AD. 1880. A further contribution to the knowledge of British Oribatidae. J Roy Micr Soc London, 3: 225–251. [Crossref] , [Google Scholar]), O. superbula (Berlese,1904 Berlese, A. 1904. Acari nuovi. Manipulus III. Redia, 2: 10–32.  [Google Scholar]) and O. calcarata (CL Koch, 1835 Koch, CL. 1835. “Deutschlands Crustaceen, Myriapoden und Arachniden”. In Regensburg, Germany: Verlag Friedrich Pustet 1–3.  [Google Scholar]) studied here for the first time, and that of the other species from the literature. The pattern of gastronotal setae in larvae is similar, except for lack of seta h ₃ in O. nortoni Behan-Pelletier, 2011 Behan-Pelletier, VM. 2011. Oribatella (Acari, Oribatida, Oribatellidae) of eastern North America. Zootaxa, 2973: 1–56. [Crossref] , [Google Scholar], while that of nymphs and adults is differentiated. The nymphs of most species have 15 pairs of gastronotal setae, but those of O. metzi Behan-Pelletier, 2011 Behan-Pelletier, VM. 2011. Oribatella (Acari, Oribatida, Oribatellidae) of eastern North America. Zootaxa, 2973: 1–56. [Crossref] , [Google Scholar] and most nymphs of O. calcarata have 13 pairs. The nymphs of most species carry the exuvial scalps of previous instars on apical parts of gastronotal setae da, while setae dm and dp, located under these scalps, are subjected to translocation, reduction in size or loss. In O. berlesei (Michael, 1898 Michael, AD. 1898. “Oribatidae”. In Das Tierreich, Lief. 3. Vol. 8 (Acarina). Berlin: Verlag von R. Friedländer und Sohn Edited by: Schulze, FE. 1–93. [Crossref] , [Google Scholar]), O. nortoni, O. quadricornuta and O. sexdentata Berlese, 1916 pair dp takes a more lateral position, compared with the larvae, in O. superbula and O. canadensis Behan-Pelletier and Eamer, 2010 Behan-Pelletier, VM and Eamer, B. 2010.

[Crossref] , [Google Scholar] it is reduced in size (in the latter species pair dm is also reduced), while O. metzi loses setae dm and dp. In contrast, the nymphs of O. calcarata do not carry the scalps, and usually lose setae c ₁ and dm. The adults of all species lose setae c ₁, c ₃ and d-series, compared with the tritonymph, and only 10 pairs of notogastral setae remain (c ₂, l-, h- and p-series), but O. quadricornuta and O. calcarata rarely retain seta c ₃ unilaterally, which indicates the order of setal loss in Oribatella according to Shaldybina (1972 Shaldybina, ES. 1972. Some morphological characters of ceratozetid moss mites (Oribatei). Ucenyje zapiski Gor Gosud Pedagog Institut, Gorki, 130: 35–66. In Russian [Google Scholar]).     

Revision of Flabelliderma Hartman, 1969 (Polychaeta: Flabelligeridae)

Atlas of the sedentariate polychaetous Annelids from California, 812Los Angeles: University of Southern California, Allan Hancock Foundation.  [Google Scholar] is redefined and its type species is re‐established. In comparison with Flabelligera Sars, 1829 Sars, M. 1829. Bidrag til Söedyrenes Naturhistorie; Förste Hæfte, 60Bergen: Dahl.  [Google Scholar], the diagnostic features include the fusion of papillae forming tubercles, often adhering sediment particles, and notopodial lobes forming large ovoid lobes. 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.

Differentiation of body form of Protoplophoroidea (Acari: Oribatida) in the light of ontogeny of three species

The differentiation of body form of Protoplophoroidea in the light of ontogeny of Cosmochthonius ponticus Gordeeva, 1980 Gordeeva, EV. 1980. Oribatid mites of the family Cosmochthoniidae (Oribatei). Zool J., 59: 838–850. Russian [Google Scholar], Sphaerochthonius splendidus (Berlese, 1904) and Haplochthonius simplex Willmann, 1930 is investigated. These species have primitive characters, like dorsal transverse scissures on the hysterosoma, four pairs of adanal and anal setae, and two pairs of exobothridial setae. However, in C. ponticus three dorsal scissures occur during ontogeny, in S. splendidus three scissures are present in the juveniles, and one scissure in the adult, while in H. simplex three scissures occur only in the adult. These species also differ by expansion of new segments in the anal region during ontogeny; in S. splendidus this expansion is the smallest, while in H. simplex is the largest. Cosmochthonius ponticus has hypertrophied, erectile setae of the e- and f-series, S. splendidus has armour-like, dorsal, pleural and ventral plates, while H. simplex has thin cuticle and short dorsal setae.     

Hydrozetes longisetosus sp. nov. (Acari: Oribatida: Hydrozetidae) – the most primitive European species of Hydrozetes from Poland

The larva, nymphal stages and adult of Hydrozetes longisetosus sp. nov. are described and illustrated, and the relationship of this species with the other European species of Hydrozetes is investigated. This species was first found at the edge of a forest lake, Dury 3, in the Tuchola Forest (Poland). Subsequently, we studied specimens that had been collected in 1976 by Dr H.M. Engelmann 40 km north of Görlitz Niederspree (Germany). Many adults of this species have three setae of the c‐series, which is rare in Hydrozetes and is considered a primitive character. Most adults have two pairs of p‐series setae, which is not common in Brachypylina and is unique among European Hydrozetes. The nymphal stages have many long setae in the marginal part of the gastronotum (whole l‐ and h‐series and seta p ₁), and some or all long setae of the c‐ and d‐series, which is unique among European Hydrozetes. In H. longisetosus neotrichy occurs in the h‐series, as in H. parisiensis Grandjean, 1948 Grandjean, F. 1948. Sul les Hydrozetes (Acariens) de l'Europe occidentale.. Bull Mus Natl Hist Nat Série 2., 20: 328–335. French [Google Scholar]. Therefore, the former species is closely related to the latter, and also to H. lacustris (Michael, 1882) and H. octosetosus Willmann, 1932 Willmann, C. 1932a. Oribatiden aus dem Moosebruch.. Archiv Hydrobiol., 23: 333–347.  [Google Scholar], which rarely retain all the c‐series setae in the adults.

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.     

Epizoic rotifers (Rotifera: Monogononta,Bdelloidea) from the gill chambers of Potamon fluviatile (Herbst, 1785)

We describe some rare epizoic rotifers found on Potamon fluviatile (Herbst, 1785) from Italy. Three species are discussed: Lecane branchicola (Piovanelli, 1903) (Monogononta, Lecanidae; new synonym: L. piovanellii Barto?, 1957 Barto?, E. 1957. Die Rädertiere der Kiemenhöhle der Süsswasserkrabbe (Potamon potamon). Vestnik Ceskoslovenské Zoologiscké Spolecnosti, 21: 376–380.  [Google Scholar]), Anomopus telphusae Piovanelli, 1903 and Embata parasitica (Giglioli, 1863) (Bdelloidea: Philodinidae). Lecane branchicola, previously considered a nomen nudum after Barto? (1957 Barto?, E. 1957. Die Rädertiere der Kiemenhöhle der Süsswasserkrabbe (Potamon potamon). Vestnik Ceskoslovenské Zoologiscké Spolecnosti, 21: 376–380.  [Google Scholar]), is redescribed, and its identity is stabilized by the designation of a neotype. Both L. branchicola and A. telphusae are particularly rare, and have been found on a few occasions only. Lecane branchicola appears to be restricted to a specific body part of their host, namely the branchial chamber. On the contrary, E. parasitica has been recorded as epizoic from several hosts and regions. SEM photographs of the trophi of the three species are presented.

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

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)..

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.     

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.

New records of Bathynellacea (Syncarida,Bathynellidae) in North America: three new species of the genus Pacificabathynella from Montana,USA

Three new species of the genus Pacificabathynella Schminke and Noodt, 1988 Schminke, H K and Noodt, W. 1988. Groundwater Crustacea of the order Bathynellacea (Malacostraca) from North America. J Crustacean Biol., 8(2): 290–299.  [Google Scholar] are described from groundwater aquifers in glaciated North America (Montana, USA). This is the first time that this genus, known previously only from the state of California, has been documented in Montana. Pacificabathynella and Paradoxibathynella Serban, 2000 Serban, E. 2000. Uenobathynella n.g., Parauenobathynella n.g., Morimotobathynella n.g., Nihobathynella n.g. et Paradoxibathynella n.g., Bathynellinae du Japón (Bathynellidae, Bathynellacea, Podophallocarida). Travaux Inst Spéol “Émile Racovitza”, 36: 3–61.  [Google Scholar] are the only genera that show sexual dimorphism in thoracopod VI. Pacificabathynella kalispellensis sp. nov. has several unique features: the setal formula of the antenna (0/2+exop/3/12/6/8/5); the setal formula of the maxilla (7/4/7/6); the presence of an epipod on thoracopod II; tufts of setulae and abundant setae on the basipod and endopod of thoracopods I to V; the epipod of thoracopod VIII female three times longer than the basipod; three smooth setae on the exopod of the female thoracopod VIII; eight spines on the endopod of the uropod and the endopod longer than the sympod, whereas the opposite is typical. Pacificabathynella stanfordi sp. nov. has several unique features: only five setae on the exopod of thoracopods II to VII, while six setae are common in the genus; only six setae on the second segment of the first pleopod; five spines on the endopod and seven setae on the exopod of the uropod. Pacificabathynella ruthae sp. nov. is the largest species and has several unique features: antennule equal in size to the antenna, whereas in the rest of the species of the genus the antenna is larger; the projection of the inner lobe of the male thoracopod VIII is bidentate and there are six spines on the endopod and nine setae on the exopod of the uropod. The three new species have slight differences in the pars molaris of the mandible and in thoracopod VIII of males, and there are other minor differences between the females and the species Pacificabathynella sequoiae. The new taxa, together with the new genus Montanabathynella described separately, represent a 30% increase in North American taxa. Considering the glaciated landscape and the fragmented nature of alluvial aquifer habitat, we believe that there is a profound lack of critical knowledge of the biogeography and biodiversity of syncarids in North America.     

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.. Siboga Exp Utk zool bot oceanog geol Geb verz Neder Oost Indie 1899–1900 aan Boord HM Siboga ond Comm van Luit GF Tydeman., 24(1a): 1–43.  [Google Scholar] and Amphinome djiboutiensis Gravier, 1902 Gravier, C. 1902. 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.     

Taxonomy of the genus Aetheomorpha Lacordaire (Coleoptera: Chrysomelidae: Cryptocephalinae: Clytrini) from China,with description of five new species
