The Scorpionflies (Mecoptera) of Indochina with the Description of New Species of Bittacus and Neopanorpa

Forty species of scorpionflies are currently known from Indochina, consisting of 36 Neopanorpa, three Bittacus, and one Bicaubittacus. I describe and illustrate five additional new species from northern and central Vietnam: Neopanorpa angustala n. sp., N. lindsleyi n. sp., N. acetabulifera n. sp., Bittacus tamdaoensis n. sp., and B. bartolozzii n. sp., and discuss their habitats. I provide additional distribution and seasonal data for Indochinese Mecoptera. Moreover, I document the first records of Mecoptera from Cambodia.
