Descriptions of two New Genera of Parasitic Hymenoptera

Abstract

Brues-The Phorid Genus Platyphorz of America 79 Described from a single male collected at Forest Hills, Mass., May 30, 1910, by Mrs. C. T. Brues. The insect was moving about among fallen leaves in an open wooded area. Ants of various kinds are abundant in the vicinity and it is possible that the species may be myrmecophilous like its European congener, P. lubboci. Platyphora coloradensis sp. nov. o. Length 1.8 mm. Black; antennm dark fulvous, darkened on the tip of the third oint; palpi pale yellow; legs testaceous, tinged with fuscous on the tibiae and fuscous on the tarsi. Pleurae pale fuscous, piceous on the posterior half of the mesopleura. Hypopygium retracted, but apparently brownish as in P. eurynota. Head structurally as in P. eurynota, and also the mesonotum, except that the dorsocentral bristles are larger. Scutellum dull, not at all shining, with shagreened surface; the series of bristles along its margin larger than in P. eurynota. Abdomen with the second and sixth segments lengthened, slightly pruinose and nearly bare on the first to fifth segments; sixth shining and clothed with sparse hairs. Pleurae and legs as in P. eurynota. Wings hyaline; heavy veins pale brown, except the apex of the costal vein which is fuscous; light veins very pale; costal bristles larger than in P. eurynota; third vein bristly to the fork and second vein bristly; third vein thickened, but not much stouter than the costa, light veins much as in P. eurynota, but the fourth and fifth are less divergent at tip and the seventh apparently farther from the margin. Halteres black, except at extreme base. Described from a single specimen collected on a window at Boulder, Col., by Mrs. T. D. A. Cockerell, July 17, 1908, and sent to me by Prof. Cockerell. This species is very similar to P. eurynota in structure, although entirely different in color and much smaller. It might perhaps be

Braconid Wasps (Hymenoptera: Braconidae) of Northern Yucatan, Mexico: Subfamilies Agathidinae and Doryctinae (excluding Heterospilus Haliday)

“…The keys of Achterberg (1990) and Wharton et al (1997) were used for the identification of the braconid species to subfamily level; keys and descriptions by Achterberg (1995) and Whitfield (1990) were used for Choreborogas, and descriptions by Ashmead (1893), Brues (1912), Rohwer (1914), Muesebeck (1922), Walley (1941) Marsh (1979) and Papp (1989Papp ( , 1993 were used for determining Mirax species.…”

“…Species of this genus have been described from North America (Ashmead 1893;Rohwer 1914;Walley 1941;Muesebeck 1922;Papp 1989) and South America (Brues 1912;Marsh 1979;Papp 1993). In Mexico, Mirax Haliday has been reported only at the genus level in several states (Sán-chez & López 2000;Wharton & Mercado 2000;Delfín & León 1997), but no species has been described or reported at this time.…”

Review of North European species of the genus Lathrolestes (Hymenoptera, Ichneumonidae) with description of one new species from Öland (Sweden)

“…L. messae Barron, 1994 Heterarthrinae, Fenusini: Messa populifoliella (Townsend, 1893) [Barron, 1994] Populus [Barron, 1994] 11.

“…The members of Lathrolestes are mostly known to be koinobont endoparasitoids, usually on leafmining sawfly larvae of the tribe Fenusini (Hymenoptera, Tenthredinidae). However L. clypeatus (Zetterstedt 1838) and L. mnemonicae (Rohwer 1914) attack leafmining lepidopteran larvae of the family Eriocraniidae (Rohwer 1914;Heath 1961;Carlson 1979) and L. zeugophorae Barron, 1994 attacks leafmining beetle larvae of the family Megalopodidae. These hosts have a similar leafmining lifestyle and are associated with deciduous trees.…”

Review and key to Nearctic Lathrolestes Förster (Hymenoptera: Ichneumonidae), with special reference to species attacking leaf mining tenthredinid sawflies in Betula Linnaeus (Betulaceae)

“…Lathrolestes luteolator (Gravenhorst, 1829) attacks several species of Caliroa. There are species that are parasitoids of leafmining lepidopterans in the Eriocraniidae (Rohwer 1914, Heath 1961, Carlson 1979), L. clypeatus (Zetterstedt, 1838 and L. mnemonicae (Rohwer, 1914). cytochrome oxidase c subunit I (COI).…”
