Examination of about 810 specimens, including multivariate morphometric analysis of 21 quantitative characters clearly separated three species, Dibrachys microgastri (Bouche, 1834), Dibrachys lignicola Graham, 1969, and Dibrachys verovesparum Peters & Baur sp. n., but allowed no further subdivision of taxa according to origin, host association or previous taxonomic concepts. A neotype is designated for D. microgastri and under this name are placed in synonymy the names Dibrachys cavus (Walker, 1835) syn. n. (including eight current junior synonyms), Dibrachys clisiocampae (Fitch, 1856) syn. n. (including five current junior synonyms), Dibrachys boarmiae (Walker, 1863) syn. n., and Dibrachys elegans (Szelenyi, 1981) syn. n. Dibrachys goettingenus Doganlar, 1987 syn. n. is synonymized under D. lignicola. The morphological analyses revealed several new qualitative and quantitative characters for separating taxa in this species complex and an identification key and diagnoses are provided for females and males. Dibrachys microgastri is a polyphagous generalist pupal ectoparasitoid of several different orders of holometabolous insects, whereas D. lignicola is a polyphagous ectoparasitoid of hosts in Diptera, Lepidoptera and Hymenoptera, and D. verovesparum is a primary or secondary parasitoid in nests of Vespidae.

查看更多>>摘要：Three embiid species of the genus Aposthonia Krauss (Oligotomidae) are recognized from Thailand (Aposthonia borneensis, A. ceylonica, A. problita sp. n.) and the new species is described. The distribution of the three species in Thailand is shown and keys to the males of 25 species of this genus and to females found in Thailand are provided.

Phymonotus is unique in having an unusually enlarged dome-like pronotum, a distinctive song, and seven additional distinctive morphological features. We believe that Phymonotus is a Pleistocene relic taxon, now endemic to geographically isolated high elevation conifer forests of the San Jacinto Mountains. Nearest relatives Agalothorax and Neduba taxa occur in lower elevation environments throughout the surrounding region. Phymonotus is a member of the katydid tribe Nedubini which has a Gondwanan distribution with additional taxa in Australia and South America (Chile and Argentina). Western North American Nedubini apparently result from a South American dispersal event. We also describe characters newly used for the description and diagnosis of Phymonotus, the dorsal and ventral lobes of the titillators, and the dorsal sclerites of the titillators. We report evidence that Phymonotus males may produce thoracic glandular secretions that are offered to mating females.
查看更多>>摘要：The genus Eleodes is the largest among the Tenebrionidae of North America, with more than 200 known species. Some are widespread, ranging from Canada to Mexico while others have a more restricted distribution. The larvae of the species, known as false wireworms are very damaging to crops in irrigated farmland. The following new species is a surprising addition to the Mexican beetle fauna, especially since it was discovered in an area where much fieldwork has been done over the years.
