Species group confracta Liu

Diagnosis. The species group “b” category has mediate-width long tegmina, comparatively short files ( Fig. 5 g–k) and the narrowest mirror ( Fig. 6 g–k). The file is widest in basal quarter, from which teeth are gradually narrower toward both ends ( Fig. 5 g–k). The songs are discontinuous and each song unit consists of numerous simple syllables ( Figs 2a, f, k ).

Included taxa. Mecopoda confracta sp. n. ( China), M. synconfracta sp. n. ( China), Mecopoda _“S” ( Figs 3 k–o, 5i, 6i; Malaysia) ( Sismondo1990), Mecopoda sp. ( Figs 5j , 6j ; Vietnam), Mecopoda elongata elongata ( Figs 5k , 6k ; India), and Mecopoda _“N” (Bali) ( Sismondo1990).
