Phenology of Zagryphus zulaya Gauld (Hymenoptera: Ichneumonidae: Tryphoninae) in a montane forest in Guatemala and a new country record for Z. vegai Gauld.

Ichneumonidae are incredibly diverse, yet there have been few Guatemalan ichneumonid studies. We studied the phenology of 215 specimens of Zagryphus zulaya Gauld (Hymenoptera: Ichneumonidae: Tryphoninae), most captured in a light trap and two Malaise traps in a montane (1850m) forest from 2002 to 2014. One of the Malaise traps caught over 95% of the specimens. The results suggest that Z. zulaya is most abundant in May, June, July, and August, the rainy season. Zagryphus vegai Gauld is newly recorded from Guatemala; it was previously known only from Costa Rica. It was found at an altitude of 1850m, though its previous known range was 700m to 1500m.
