A new parasitoid (Hymenoptera: Braconidae: Aphidiinae) of the invasive bamboo aphids Takecallis spp. (Hemiptera: Aphididae) from Western Europe

A long-term survey of tritrophic (plant–aphid–parasitoid) associations in the urban ecosystems of Lleida (Catalonia) and Paris (France) resulted in the detection of associations of two bamboo aphids, Takecallis arundinariae (Essig) and Takecallis taiwanus (Takahashi), respectively, with a new aphid parasitoid species. Trioxys remaudierei Starý & Rakhshani sp. nov. is described and illustrated as a unique parasitoid of Takecallis aphids outside the area of their origin. The new species is easily distinguishable from its congeners in having the ventral prongs of the abdomen fused over two-thirds of their length, then bifurcated towards the tip. The only morphologically similar species is Trioxys betulae (Marshall), which exhibits a clearly different prong shape (and has a different host range, Symydobius Mordvilko and Clethrobius Mordvilko). The new species is compared with allied taxa associated with bamboo aphids. The occurrence of Takecallis taiwanus on bamboo is recorded in France for the first time.

Review of the microphysid genus Loricula Curtis in Japan (Hemiptera: Heteroptera: Microphysidae), with descriptions of three new species

Japanese fauna of the cimicomorphan family Microphysidae is documented. Four species of the genus Loricula Curtis are recognised, including three new species herein described from Japan, Loricula miyamotoi, L. nikko and L. yakushima, representing the first discovery of new taxa in the twenty-first century for the Asian Microphysidae. A single known species, L. pilosella Miyamoto, is rediagnosed. A key is provided to distinguish both sexes of the Japanese Loricula species.

Raspailiidae (Porifera: Demospongiae: Axinellida) from the Mexican Pacific Ocean with the description of seven new species

The taxonomy of the family Raspailiidae has always been controversial. The family was first included in the order Poecilosclerida. It was then allocated to the order Axinellida and later moved back to Poecilosclerida. Currently with the development of molecular tools it has been assigned to the order Axinellida. In this contribution we describe 10 species from the Mexican Pacific Ocean. Seven of them are new to science: Raspailia (Parasyringella) rubra sp. nov., Raspailia (Raspaxilla) hymani (Dickinson 1945 Dickinson, MG. 1945. Sponges on the Gulf of California. Allan Hancock Pac Exp, 11(1): 1–251.  [Google Scholar]), Raspailia (Raspaxilla) hyle (de Laubenfels 1930 de Laubenfels, MW. 1930. The sponges of California. (Abstracts of dissertations for the degree of doctor of philosophy). Stanford Univ Bull, 5(98): 24–29.  [Google Scholar]), Aulospongus cerebella (Dickinson 1945 Dickinson, MG. 1945. Sponges on the Gulf of California. Allan Hancock Pac Exp, 11(1): 1–251.  [Google Scholar]), Aulospongus californianus sp. nov., Aulospongus aurantiacus sp. nov., Eurypon patriciae sp. nov., Eurypon tylospinosum sp. nov., Eurypon diversicolor sp. nov. and Eurypon brunus sp. nov. We discuss the genus Eurypon and include a table for all the species described worldwide with some comments about this genus. http://www.zoobank.org/urn:lsid:zoobank.org:pub:D462084B-EE9C-4C61-884A-C9DB70003B4A     

Two new nematodes,Pseudelzalia longiseta gen. nov., sp. nov. and Paramonohystera sinica sp. nov. (Monhysterida: Xyalidae), from sediment in the East China Sea

Pseudelzalia longiseta gen. nov, sp. nov. and Paramonohystera sinica sp. nov. from subtidal sediment in the East China Sea are described. Pseudelzalia is characterized by 6 labial papillae and 10 cephalic setae, cylindrical buccal cavity, elongate (>2 anal body diameter) spicules, and conico-cylindrical tail devoid of terminal setae. It differs from Elzalia by the absence of terminal setae. Pseudelzalia longiseta sp. nov. is 647–853 μm long, has 7–8 μm long cervical setae, 11–14 μm long caudal setae, 25–41 μm long spicules about 2.1–2.7 anal diameter, and pointed tail-tip. Paramonohystera sinica possesses 12 cephalic setae, a character found in four congeners: Paramonohystera buetschlii (Bresslau and Schuurmans Stekhoven in Schuurmans Stekhoven, 1935, Paramonohystera pilosa Boucher, 1971, Paramonohystera concinna Lorenzen, 1977 and Paramonohystera halerba Fadeeva and Belogurov, 1987. It differs from P. buetschlii by shorter body (933–1023 μm versus 2000–2200 μm); from P. pilosa by the much shorter spicules (79–88 μm versus 167 μm) and narrower head (13–16 µm versus 32 µm); from P.concinna by smooth cephalic setae (versus segmented); and from P. halerba by the absence of two rows of setae on the ventral side of the tail (versus present). Based on the evaluation of nominal species, we recognize 14 valid species and provide an emended diagnosis and a tabular key for Paramonohystera.

Earthworms (Annelida: Oligochaeta) of Sao Tomé

During a soil zoology expedition to Sao Tomé Island, among other members of the soil fauna, earthworms were collected. During this collecting trip some 170 earthworm specimens belonging to 18 species were gathered of which two, Dichogaster (Diplothecodrilus) coeruleoviridis and Dichogaster (Diplothecodrilus) zicsii, proved to be new to science. In addition, a small sample from the same locality was also examined and Dichogaster (Dichogaster) thomeana Cognetti, 1910 Cognetti de Martiis, L. 1910. Lombrichi raccolti dal Cav.

New records of West and South African Bathyporeia,with the description of four new species and a key to all species of the genus (Crustacea,Amphipoda)

New data on the warm temperate and tropical east Atlantic Bathyporeia species are presented. Four new species are described: Bathyporeia cunctator sp. nov. from South Africa, B. chevreuxi sp. nov. from Senegal, B. gladiura sp. nov. from South Africa, and B. griffithsi sp. nov. from Namibia. Bathyporeia cunctator sp. nov. and B. chevreuxi sp. nov. are very closely related to the west European B. tenuipes Meinert, 1877 and the Mediterranean B. lindstromi Stebbing, 1906 Stebbing, T. R. R. 1906. Amphipoda 1: Gammaridea.. Das Tierreich, 21: 1–806.  [Google Scholar]; these four cryptic species forming the complex tenuipes. Bathyporeia griffithsi sp. nov. and B. gladiura sp. nov. are highly distinctive new species. The morphotype “sunnivae” of Bathyporeia guilliamsoniana is recorded for the first time outside the Mediterranean Sea, in the Canary Islands. An identification key to all known Bathyporeia species is given.     

Composition of meiobenthonic Platyhelminthes from brackish environments of the Galician and Cantabrian coasts of Spain with the description of a new species of Djeziraia (Polycystididae,Kalyptorhynchia)

From 1997 to 1999, the fauna of free‐living Platyhelminthes of the rias ecosystem was studied along the Galician and Cantabrian coast in northern Spain. In total, 72 platyhelminth species are listed in this study. Forty‐two species represent new records for the Iberian Peninsula, three of which represent new genera records. A new species belonging to the genus Djeziraia (Polycystididae, Kalyptorhynchia), Djeziraia longistyla sp. nov., is described in this paper. In this broad‐scale study, a large data set (27 localities) of the estuaries of northern Spain allowed an analysis of the turbellarian species assemblages and the relation of species distributions to salinity, conductivity, oxygen, temperature, and sediment characteristics. Species assemblages (species diversity) of each habitat of the brackish water ecotone are shown. The present study contributes to knowledge on the ability of adaptation of free‐living Platyhelminthes to regimes of brackish water ecotones.
