Ordo: Hymenoptera
Familia: Ichneumonidae
Name
Himertosoma Schmiedeknecht, 1900 – Wikispecies link – Pensoft Profile
- HimertosomaYu and Horstmann (1997) for synonymy.
Remarks
According to Townes (1970)[1] and Chandra and Gupta (1977)[2], this genus can be separated from other atrophine genera by the combination of the following character states: occipital carina complete, its lower end joining hypostomal carina; mesoscutum often smooth; areolet always absent; tarsal claws sometimes only partly pectinate; first metasomal tergite covered with longitudinal striation, with more or less distinct median dorsal carina basally, spiracle in front of middle (Figs 7, 8); laterotergite of fifth metasomal tergite not separated by a crease; exposed portion of fifth metasomal tergite of female only about 0.5 times as long as exposed portion of fourth metasomal tergite; and ovipositor distinctly longer than hind tibia (more than 1.4 times as long as hind tibia). However, the classification of Himertosoma and its most similar genus, Lissonota Gravenhorst, is still in dispute; Himertosoma can be separated from Lissonota only by a single character, the absence of the crease separating laterotergite of the fifth metasomal tergite. Their generic status should be reconsidered in future study.
The genus Himertosoma, hitherto known only from the Philippines in the Oriental Region (Chandra and Gupta 1977[2]), was discovered for the first time on Amamioshima Island, the North Ryukyus, represented by the following new species.
