A revision of the genus Pseudoechthistatus Pic (Coleoptera, Cerambycidae, Lamiinae, Lamiini)
The genus Pseudoechthistatus Pic, 1917 is redefined and revised. Five species of the genus are described as new, P. sinicus sp. n. and P. chiangshunani sp. n. from central Yunnan, China, P. pufujiae sp. n. from western Yunnan, China, and P. holzschuhi sp. n. and P. glabripennis sp. n. from southern Yunnan and northern Vietnam. Pseudoechthistatus birmanicus Breuning, 1942 is excluded from the fauna of China. Three poorly known species, P. obliquefasciatus Pic, 1917, P. granulatus Breuning, 1942, and P. acutipennis Chiang, 1981 are redescribed, and the type localities of the former two species are discussed. Endophallic structure of seven species in inflated and everted condition are studied and compared with their relatives. Illustrations of habitus and major diagnostic features of all species are provided. Some biological notes are reported. An identification key as well as a distributional map are presented.
