Zephronia manca Attems, 1936: 169; Sundara 1970 : 127 (list); Golovatch 1983 (list); Enghoff et al. 2004 : 32 (list); Jeekel 2001 : 20 (list); Wesener 2016b : 33 (list). Syntypes. ♂ and ♀, NHMW 2239 (not examined). Distribution. Vietnam: D'Ran , Lam Dong Prov., near Dalat; Peak Lang Biang, Lam Dong Prov., S. Annam. India: Dhobie Jhora, Kurseong, eastern Himalayas ( Attems 1936 ). Figure 6. Sphaerobelum pumatense sp. nov., ♂ holotype ( A-G ) and ♀ paratype ( H ). A, B Left posterior telopod, anterior and posterior views, respectively C-E left anterior telopod, anterior, lateral and posterior views, respectively F left leg 9, anterior view G left antenna H left coxa and prefemur 2 with vulva, posterior view. Scale bars: 1.0 mm, D drawn not to scale. Remarks. The drawings of the telopods, as well as the extremely enlarged operculum of the ♀ vulva as depicted in the original description ( Attems 1936 ) clearly show this species to be a member of the genus Sphaeropoeus , related to the other species mentioned below. Only a full revision of the type series, which contains syntypes from several localities in Vietnam and India, may clarify whether several species are actually hidden under the name S. manca . The posterior telopods and other characters are clearly different in S. manca compared to the two other species, as well as to Sphaeropoeus maculatus (Verhoeff, 1924) which is redescribed below.
