description: Genus Locoptiris Villiers, 1943   
 Locoptiris Villiers, 1943: 227. Type species by original designation: Locoptiris burgeoni Villiers, 1943.   
 References. WYGODZINSKY & USINGER (1963): 51 (diagnostic characters, notes); VILLIERS (1986): 216 (diagnostic characters of included species); MALDONADO CAPRILES (1990): 336 (catalogue).   
 Diagnosis. Distinguished from all other genera of the subfamily Holoptilinae by the combination of the following characters: body very small (2.5–3.5 mm); antenna and hind tibia densely clothed with stiff setae much longer than diameter of respective segments; antennal segments III and IV fused, therefore antenna 3-segmented, segment II not produced beyond base of segment III+IV; abdominal trichome absent.   
 Notes. Locoptiris currently contains two species, L. burgeoni Villiers, 1943 and L. couturieri Villers, 1986, both occurring in tropical Africa. WYGODZINSKY & USINGER (1963: 51) noted that Ptilocerus pendleburyi Miller, 1940, described from the Malay Peninsula, shows very close resemblance to Locoptiris and may belong to this genus; however, they pointed out that the African species differs from P. pendleburyi in a few characters probably of generic importance. Consequently, apparently largely based on zoogeographical considerations too, they did not made any formal change in the placement of the latter species.   
 Re-examination of the type material of P. pendleburyi and L. couturieri, examination of several specimens of L. burgeoni, and direct comparison of the holotype of L. taiwanensis to both African species lead the first author to the following conclusion. The two African species, Ptilocerus pendleburyi, and L. taiwanensis sp. nov. described below are strikingly similar morphologically, and apparently closely related phylogenetically. Although a few characters could be observed to separate the African and the Asian forms (Table 1), none of them are considered as of genus level importance. Since it seems unjustified to separate the taxa at genus level, we regard all the four species as congeneric, and therefore we place the new species to Locoptiris, furthermore we propose the following new combination: Locoptiris pendleburyi (Miller, 1940), comb. nov. We define the following, apparently monophyletic species groups within Locoptiris: L. burgeoni species group (L. burgeoni, L. couturieri), and L. pendleburyi species group (L. pendleburyi, L. taiwanensis sp. nov.).
