Cremastinae
Guides
Cremastus
Cremastus is a genus of ichneumon wasps in the family Ichneumonidae, subfamily Cremastinae. The genus was established by Gravenhorst in 1829 and contains multiple described species. Members are parasitoid wasps, with females possessing an ovipositor for host parasitization. Several species have been described from western North America by Dasch, including C. amoenus, C. aridus, C. atratus, C. planus, C. prolatus, and C. stenotus.
Eiphosoma
Eiphosoma is a genus of ichneumonid wasps in the subfamily Cremastinae, established by Cresson in 1865. Species in this genus are larval endoparasitoids primarily associated with noctuid moth larvae, particularly the fall armyworm (Spodoptera frugiperda). Several species have been investigated as biological control agents for agricultural pests, with E. vitticolle and E. laphygmae receiving particular attention for their potential in integrated pest management. The genus exhibits a New World distribution centered in the Neotropics, with documented species from Cuba, Colombia, Mexico, Brazil, and Costa Rica.
Nothocremastus
Nothocremastus is a genus of ichneumon wasps in the family Ichneumonidae, established by Dasch in 1979. The genus is represented by the species Nothocremastus intermedius, described from California. Like other ichneumonids, members are parasitoid wasps, though specific host associations remain undocumented in available sources.
Pristomerus
Pristomerus is a genus of parasitoid wasps in the family Ichneumonidae, subfamily Cremastinae, distributed worldwide with greatest diversity in tropical regions. Members are solitary koinobiont endoparasitoids that attack concealed larvae of small Lepidoptera. Several species have been employed in biological control programs. The genus exhibits high regional endemism, with 49 species recognized from the Afrotropical region, 22 from Australia (19 newly described in 2016), and 15 from Madagascar (12 endemic).
