Ⅵ.15, by Liang Zhao-ke; Allotype ♀, Hainan Island (Tong shi), 1982. Ⅳ. 6, by Liang Zhao-ke.2. Thecocarcelia seiula sp. nov.This species is closely related to Th. hinmacula sp. nov., but differs from the latter by ocellar bristles situated behind the fore ocellus; reclinate orbital setae 2 pairs, interfrontal area narrower; R4+5 with 3 setulae on node (fig. 6b); 5th tarsomere of frontal leg in male obviously enlarged (fig. 6c).Boby length 6 mm.Holotype ♀, Hainan Island, 1989, by Dai Neng-hui; paratype 1♀, Hainan Island, Ⅷ. 8. 1982. by Lu Chuan-de.
