          Five new species of Tersilochinae ( Ichneumonidae ) are described from Mexico: Meggoleus hidalgoensis sp. nov., M. whartoni Khalaim, sp. nov., Phradis belovi Khalaim, sp. nov., Stethantyx covida sp. nov., and St. oaxacana sp. nov. Meggoleus whartoni Khalaim, sp. nov. is also recorded from Panama, and St. covida sp. nov. from Guatemala. The species recently described from Mexico Probles contrerasi Khalaim & Ruíz-Cancino is transferred to the genus Gelanes Horstmann, comb. nov. A partial key to the species of Meggoleus with small propodeal spiracles and a key to Mexican species of Phradis are provided.

            Mexican species of the genus Stethantyx Townes (Hymenoptera, Ichneumonidae, Tersilochinae)

            Abstract Six species of the genus Stethantyx Townes are found to occur in Mexico. One species, S. mexicana sp. n., is described as new, and four recently described Neotropical species, S. alajuela Khalaim & Broad, S. heredia Khalaim & Broad, S. osa Khalaim & Broad and S. sanjosea Khalaim & Broad, are new records from Mexico. A key to species of Stethantyx occurring in Mexico is provided.

              Tersilochinae (Hymenoptera: Ichneumonidae) of Costa Rica, part 2. Genera Megalochus gen. nov. and Stethantyx Townes

              Two Costa Rican genera, Megalochus gen. nov. and Stethantyx Townes, are revised. These genera comprise a distinctive generic group that we refer to as the Stethantyx genus-group, veins Rs+2r and Rs angled more than 90 degrees, vein 2rs-m and abscissa of M between 2rs-m and 2m-cu not or very weakly thickened, hind wing with vein cul&cu-a (nervellus) more or less vertical, and prepectal carina with upper end not reaching anterior margin of mesopleuron, continuing above and backwards to the subtegular ridge. Both genera include medium sized to large species with body length 4.0 to 15.0 mm. Megalochus comprises only the type species, M. grandis sp. nov., occurring in Costa Rica, Ecuador and southern Brazil. It is the largest representative of the subfamily, with a body length of 10.5 to 15.0 mm. Megalochus differs from Stethantyx, besides the larger body size, by the slenderer first metasomal segment, which is round in cross-section and lacking glymmae, propodeum and metapleuron with coarse rugae, and shortened antennae with strongly transverse flagellomeres. Stethantyx is the dominant, most species-rich genus in the Costa Rican tersilochine fauna and probably in the Neotropical region. Twenty two species of this genus were discovered in Costa Rica, all are new: S. alajuela sp. nov., S. altamira sp. nov., S. aprica sp. nov., S. cacaoensis sp. nov., S. cartagoa sp. nov., S. cecilia sp. nov., S. curvator sp. nov., S. guanacasteca sp. nov., S. heredia sp. nov., S. limona sp. nov., S. mesoscutator sp. nov., S. niger sp. nov., S. nigrofemorata sp. nov., S. notaulator sp. nov., S. orosia sp. nov., S. osa sp. nov., S. propodeator sp. nov., S. pseudoorosia sp. nov., S. pseudoosa sp. nov., S. puntarenasa sp. nov., S. sanjosea sp. nov. and S. tenoriosa sp. nov. A key for distinguishing the genera Megalochus and Stethantyx, and a key to 22 Costa Rican species of Stethantyx are provided.
