Shima, 2002. Systematic study of the genus Peribaea Robineau-Desvoidy of East Asia (Diptera: Tachinidae).– Tijdschrift voor Entomologie 145: 115-144, figs. 1-19. [ISSN 0040-7496]. Published 1 June 2002. The East Asian species of the genus Peribaea Robineau-Desvoidy are revised. Twelve species are recognized, eleven of which are classified into four species groups: the fissicornis group, egesta group, orbata group, and minuta group. One species, P. trifurcata, is treated as incertae sedis. The autapomorphies of these species groups are defined and characters illustrated: fissicornis group: – male genitalia with distiphallus bearing strong spines ventrally; egesta group: – epiphal- lus absent, ventral part of distiphallus raised along midline; orbata group: – postgonite distinct- ly bifid apically, upper lobe short, lower lobe long and pointed apically; distiphallus subrectan- gular in shape, sclerotized on dorsal and ventral portion with some spinules ventrally in lateral view, middle portion weakly sclerotized or membranous; minuta group: – distiphallus suboval in shape, broadly sclerotized in lateral view bearing some spinules ventrally. The following six species are described from Japan and China: P. abbreviata sp. n., P. apaturae sp. n., P. caesiata sp. n., P. egesta sp. n., P. glabra sp. n., P. hongkongensis sp. n. Diagnoses of all species and de- scriptions of new species are given, and a key to the twelve species is provided.
