We describe a new genus, and a new species, of parasitoid--Tanzawana flavomaculata Watanabe & Kasparyan (Hymenoptera: Ichneumonidae: Ctenopelmatinae)--based on material collected in Honshu, Japan. As T. flavomaculata is found on Fagineura crenativora Vikberg & Zinovjev, 2000 (Hymenoptera: Tenthredinidae), a serious pest of beech tree, this parasitoid is an important natural enemy of F. crenativ...

Details of the life cycle of Aneugmenus merida Smith (Hymenoptera: Tenthredinidae) reared under laboratory conditions are reported. Females may produce parthenogenetic or non-parthenogenetic eggs. After eclosion, males of A. merida go through five larval instars, pre-pupa, pupa and imago. The complete life cycle lasts approximately 44 days. Larvae feed on bracken [Pteridium caudatum (L.) and Pt...

The Japanese species of the sawfly genus Siobla Cameron, 1877, are revised and keyed.

Sawflies were collected in Ethiopia during 2010-2013. Three species represent new records for the country: Arge deckerti Koch, 2005, Athalia excisa Koch, 2006 and Xenapates nigrifrons Koch, 2012. Arge flavifrons Mocsáry, 1909, syn. n. and A. transvaalensis Cameron, 1911, syn. n. are subjective synonyms of A. micheli (Buysson, 1900) that is re-described here. Athalia fumosa Gribodo, 1879 sp. rev...
