Species diversity : an international journal for taxonomy, systematics, speciation, biogeography, and life history research of animals 9 (4), 375-381 (2004)

Scythropochroa radialis Lengersdorf, 1926 is recorded from Japan (Honshu and Kyushu) as the first representative of this genus from East Asia. The female of this species is redescribed based on the Japanese specimens and compared with a closely similar species, S. gressitti Steffan, 1969 from Micronesia. The egg and xylophagous larva of S. radialis are described for the first time. The biology and larval morphology of Scythropochroa are briefly discussed.
