1986] Porter — Thyreodon from Costa Rica 139 
Summary 
Thyreodon santarosae n. sp. differs from its relatives in the Atri- 
color species group by having the hind propodeal face broadly pol- 
ished. It was obtained only by rearing from ceratocampine saturniids 
(Lepidoptera) in Tropical Deciduous Forest at Santa Rosa National 
Park in northeast lowland Costa Rica. Host larvae were collected at 
3-20 m in the forest overstory. Other known Thyreodon are active 
near ground level and those few that have been reared parasitize 
sphingid Lepidoptera.
