Description of a new Procystiphora species (Diptera: Cecidomyiidae) inducing galls in culms of Sasa nipponica (Poaceae) in Japan, and the first discovery of an inverted ovipositor in Diptera

Procystiphora uedai sp. nov., a cecidomyiid inducing subglobular galls on Sasa nipponica Makino and Shibata on Mount Ôdaigahara, Nara Prefecture, Japan is described herein. This species is distinguishable from the three known congeners by the following characteristics of the female post-abdomen: tergite VIII concave at both anterior and posterior margins; tergites VII, VIII and sternite VII unsclerotized; ovipositor–dorsoventrally inverted. Most individuals of this gall midge are univoltine and pupate in the galls in early September, but some individuals enter prolonged diapause at the third larval stadium and remain in the mature galls until the following year. Larvae of this species are attacked by two parasitoid species, Pediobius sasae Hansson (Eulophidae) and Torymus sp. (Torymidae).

Description of a new genus with four new species of termite‐guest rove beetles (Coleoptera: Staphylinidae: Aleocharinae) associated with Hodotermopsis sjostedti (Isoptera: Termopsidae)

Hodotermopsiphila gen. nov. is described to include four termitophilous species: H. maruyamai sp. nov. (Yaku‐shima, Japan), H. nitens sp. nov. (Yaku‐shima, Japan), H. longisetosa sp. nov. (Taiwan), and H. sugayai sp. nov. (Taiwan and northern Laos). These species are associated with the damp‐wood termite, Hodotermopsis sjostedti Holmgren, 1911. Hodotermopsiphila species share possible apomorphic character states with three termitophilous species, Hodotermophilus gloriosus, Yakuus iwatai, and Termophidoholus formosanus, which are also associated with H. sjostedti.     

Host specialization is ancestral in Torymus (Hymenoptera,Chalcidoidea) cynipid gall parasitoids

The host range of parasitoids varies greatly among species: Some only parasitize one to a few hosts (specialists), while others parasitize multiple species or a variety of host types (generalists). The direction of most host range shifts in parasitoid groups, that is from generalist to specialist or, alternatively, from specialist to generalist, is unknown. To explore the origin of host range shifts, we studied a clade within the genus Torymus (Hymenoptera, Chalcidoidea) that includes both generalist and specialist parasitoids of Cynipidae (Hymenoptera). We analysed the phylogenetic relationships of the species of Torymus on the basis of two gene fragments (cox1 and ITS2) of 246 specimens and performed an ancestral state reconstruction of the specialist/generalist trait. Our results revealed the following: (a) The ancestral state of this group of Torymus is specialist, with the generalist state evolving through a loss of specialization. (b) The species Torymus cyaneus and Torymus flavipes both have a strong genetic structure, suggesting the existence of different biological identities. (c) There has been a host plant shift in the lineage(s) leading to Torymus rubi and Torymus bedeguaris from galls on Quercus to those on Rosaceae. (d) The alien species Torymus sinensis and the native European species Torymus notatus are phylogenetically closely related. (e) Speciation within Torymus was likely associated with the diversification of their cynipid hosts, which itself was driven by the dramatic changes in climate and vegetation that occurred during the Miocene.

Two new freshwater species of the genus Jesogammarus (Crustacea: Amphipoda: Anisogammaridae) from northern Japan

Two new anisogammarid species belonging to the genus Jesogammarus were obtained from freshwater habitats from northern Japan. They are Jesogammarus (J.) fujinoi sp. nov. and Jesogammarus (J.) shonaiensis sp. nov. The former new species is diagnosed by the pleonites without spine and the telson without distolateral spine. The other new species differs from the congeneric species in having many dorsal spines on pleonites 1-3.     

Two new species of diplosoma (Ascidiacea: Didemnidae) bearing prokaryotic algae prochloron from Okinawajima (Ryukyu Archipelago, Japan)

Two new species of didemnid ascidians, Diplosoma ooru sp. nov. and Diplosoma simileguwa sp. nov., are described from coral reefs on Okinawajima (Ryukyu Archipelago, Japan). These two species form green colonies, having a symbiotic association with a prokaryotic alga Prochloron sp. The former species was found at the reef edges in the subtidal zone and the latter was found in a shallow reef lagoon. In these species, the colonies are thinner and the zooids are smaller than those of any other Prochloron-bearing Diplosoma species so far described. Moreover, each of the present new species has a unique combination of stigmatic numbers: 5 stigmata in the first and third rows, 6 in the second row, and 4 in the fourth in D. ooru; 4 stigmata in the first and third rows, 5 in the second row, and 3 in the fourth in D. simileguwa. In both of the new species, the retractor muscle emerges from the underside of the thorax. Larval morphology of D. ooru is also described.
