The species recognized are: Baibarana bicolor sp. nov. (Vietnam), B. longispina sp. nov. (Laos and Thailand), B. rufofasciata sp. nov. (Vietnam), B. sinuata sp. nov. (Vietnam), B. uchidai Matsumura (Taiwan), Telogmometopius angulatus sp. nov. (Malaysia: northern Borneo), T. bicarinatus sp. nov. (northeastern India), T. bifasciatus sp. nov. (Malaysia: northern Borneo), T. carinilabratus (Chou and Wu) (from Baibarana Matsumura), comb. nov. (southwestern China: Yunnan; Tibet), T. himalayensis sp. nov. (northeastern India: east Himalayas, southwestern China: Tibet), T. obsoletus Jacobi, 1921 (southern and central China: Hubei, Gansu, Sichuan, Guizhou, ?Jiangxi), T. rangoonensis sp. nov. (Burma), T. sabahensis sp. nov. (Malaysia: Sabah), and T. sarawakensis sp. nov. (Malaysia: Sarawak). Descriptions and keys to genera and species are provided together with structural illustrations. Scanning electron micrographs of the antennal sensilla, rostral apex, and male genitalia of the two genera, are provided for the first time. A lectotype is designated for Telogmometopius obsoletus Jacobi. [ABSTRACT FROM AUTHOR]
