Descriptions of two new endoparasitic cecidomyiids (Diptera: Cecidomyiidae) from Japan

Two endoparasitic species of Cecidomyiidae (Diptera) new to science are reported from Japan. Females of Endaphis psyllophaga sp. nov. lay their eggs on the wing of Calophya nigridorsalis (Hemiptera: Psylloidea: Calophyidae) on Rhus succedanea (Anacardiaceae), and newly hatched larvae bore into the adult body. The six nominal species of the genus Endaphis are endoparasitoids of aphids. The genus Endopsylla, which is morphologically similar to the genus Endaphis, consists of two species whose larvae attack psyllids or tingids. Females of Endaphis muraii sp. nov. lay their eggs near colonies of host aphids and newly hatched larvae bore into the body of aphids such as Macrosiphum euphorbiae and Aphis glycines (Hemiptera: Aphididae). The two new species are described, illustrated, and compared to known congeners, and information is given for the two species on their distribution, host range and ecological traits. Now, E. muraii is considered to be a potential biological control agent against aphids.     

Black-tie dress code: two new species of the genus Toxomerus (Diptera, Syrphidae)

Toxomerus hauseri Mengual sp. n. and Toxomerus picudus Mengual sp. n. are described from Peru and Ecuador respectively. Toxomerus circumcintus (Enderlein, 1938) is treated as a valid species and not considered synonym of Toxomerus marginatus, and Toxomerus ovatus (Hull, 1942) is considered junior synonym of Toxomerus nitidus (Schiner, 1868). An identification key for the Toxomerus species with dark abdomens is given along with diagnoses for each studied species.

Sensilla and Cuticular Appendages on the Female Abdomen of Lasioptera rubi (Schrank) (Diptera,Cecidomyiidae)

Studies by SEM and TEM revealed 6 types of integumental appendages on female uromeres VIII-X in Lasioptera rubi: microtrichia, not innervated; spines, probably without sensory function; nonporous sensory hairs, each containing one dendrite ending with a tubular body indicating a tactile function; uniporous sensory hairs, each innervated partly by 3 dendrites indicating a chemosensory function, partly by an additional dendrite with a tubular body indicating a tactile function; scoop-like sensilla, each containing partly a branched structure of dendrites in the distal half of the sensillum indicating an olfactory function, partly an unbranched dendrite ending at a pore near the base of the sensillum, most probably registrating chemical stimuli by contact or gustation; finally, nonporous bristles, all or some of them innervated, in a manner indicating a tactile function. In addition, two scolopophorous proprioceptors were found inside uromere X. The nonporous sensory hairs, the uniporous sensory hairs and the scolopophores may be used by the midge to determine the mechanical and chemical properties of potential oviposition sites. The spines and nonporous bristles may function as conidia carriers.     

A new genus and species of gall midges of the supertribe Heteropezidi (Diptera,Cecidomyiidae) found in Eocene amber from Sakhalin

A new genus and species of pedogenetic gall midge, Estoperpetua sakhalinica gen. et sp. nov., of the tribe Heteropezini (subfamily Lasiopterinae) is described. Gall midges have not been recorded in Eocene amber of Sakhalin. A female with 4-segmented tarsi, large transparent triangular sensoria on flagellomeres, short wings and legs, and long 2 + 9-segmented antennae is described. Heteropezidi shows the greatest generic and species diversity in the Late Eocene Rovno amber. Representatives of this supertribe were also found in the Late Eocene Baltic amber, Early Eocene Oise amber, Miocene amber from Mexico and Dominican Republic, and African copal. Heteropezidi from different amber faunas are reviewed.

New genus and species of the family stichaeidae from Hokkaido,Japan

Specimens of a new genus and species of the stichaeid fish,Leptostichaeus pumilus, were collected from the Okhotsk Sea off Hokkaido in Japan. The present new genus and species clearly differs from all the other genera and species of the stichaeid fishes in the following characters: 3 or 4 pectoral fin rays; 10 or fewer caudal principal rays; 79–82 dorsal spines; no pelvic fin; last interneural spine supporting a single dorsal spine; infraorbital, occipital and lateral line canals absent; moderate size of dorsal spine shorter than eye diameter; membranes of dorsal and anal fins widely connected with caudal fin; a large black spot divided by a yellow band present just above gill cover.     

Classification of the gall midge tribe Aphidoletini (Diptera,Cecidomyiidae: Aphidoletidi) with descriptions of a new genus and a new species from the Kurile Islands

A new classification is proposed for the gall-midge tribe Aphidoletini including 4 subtribes, 10 genera, and 18 species: Aphidoletina—3 genera with 7 species (Aphidoletes, Tribremia, Ligulodiplosis), Monobremiina subtrib. n.—2 genera with 5 species (Monobremia, Shikotanodiplosis gen. n.), Aculeatodiplosina subtrib. n.—2 genera with 2 species (Aculeatodiplosis, Setodiplosis), and Triommatomyiina—3 genera with 4 species (Triommatomyia, Tingidoletes, Chanchudiplosis). New subtribes and a new genus with a new species are described. Shikotanodiplosis sundukovi gen. et sp. n. differs from Monobremia in a wide and curved aedeagus, basally swollen sclerotized hypoproct, and small basal lobes of the gonocoxites. Keys to the subtribes, genera, and species of Aphidoletini are given. The diagnoses of Aculeatodiplosis fasciata Fedotova et Sidorenko, 2005, Setodiplosis unifaria Fedotova, 2006, and Triommatomyia Mamaev, 1961 are supplemented with biometrical characters. Tribremia aphidophaga Marikovskij, 1956 is resurrected from synonyms of Aphidoletes aphidimyza (Rondani, 1847).     

Tripius gyraloura n. sp. (Aphelenchoidea: Sphaerulariidae) parasitic in the gall midge Lasioptera donacis Coutin (Diptera: Cecidomyiidae)

A new nematode, Tripius gyraloura n. sp., is described from the arundo gall midge, Lasioptera donacis Coutin (Diptera: Cecidomyiidae). This gall midge is being considered as a biological control agent for use in North America against the introduced giant reed Arundo donax (L.) (Poaceae: Cyperales). Thus the present study was initiated to investigate a nematode parasite that was unknown at the time studies with L. donacis were initiated. The new species has a rapid development in the fly host and the mature parasitic female nematodes evert their uterine cells in the hosts’ hemolymph. Because large numbers of nematodes sterilise the host, eradication of the parasite from laboratory colonies of the midge may be necessary before populations of the fly are released.     

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).     

A new species and new synonymy in the genus Silbomyia Macquart (Diptera: Calliphoridae)
