Two new species of the genera Acerastes and Messatoporus (Hymenoptera: Ichneumonidae: Cryptini) from Mexico

D.R. Kasparyan

Abstract. Two species of the tribe Cryptini (Hymenoptera: Icneumonidae: Cryptinae), Acerastes nervellatus sp. nov. and Messatoporus atratus sp. nov., are described from Mexico. It is shown that Neotropical species of the genera Messatoporus Cushman, 1929 (90 species) and Polycyrtus Spinola, 1840 (155 species) in North and South Americas are mostly different, and only 2–6% of the species of these genera occur in both faunas. It suggests a high degree of isolation of these faunas from each other.
