A. sakaii Sasaji, are identified for the first time in Korea. Illustrations of habitus,
descriptions, and line drawings of diagnostic characters are provided.

Introduction
Key to species of Aspidiphorus in Korea
The beetle family Sphindidae contains 65 species in nine
genera from the world (McHugh 2002; Forrester & McHugh
2007). Most adults and larvae feed on spores of slime mold.
Two genera and five species have been reported from East
Asia (Smetana 2007).
Members of Sphindidae are characterized by the combination of the following features: body light brown to red brown,
surface pubescent; antennae with 10–11 antennomeres,
apical 2–3 antennomeres large, formed abrupt club; frontoclypeal suture arched; mandible with large central tubercle
and setose cavity on dorsal surface; pronotum oval, convex;
elytral punctures seriate; tibial spurs usually absent; tarsal
formula 5-5-5 in female and 5-5-4 in male.
In this paper, we report the family Sphindidae and two
species – Aspidiphorus japonicus Reitter and A. sakaii Sasaji
– for the first time in Korea. We provide illustrations of
habitus, descriptions and line drawings of the diagnostic
characters. The specimens studied are deposited in the Chungnam National University Insect Collection (CNUIC,
Daejeon), Korea.
