Genus Drepanococcus Williams & Watson, 1990

Type species: Eriochiton cajani Maskell, 1891a, by original designation.

Diagnosis. Anal cleft short, about 1/9 of body length. Dorsum with anal plates each with conical inner margin setae and apical setae (Figs 3E, 5D); dorsal setae absent; and tubular ducts absent. Marginal setae conical (Figs 3B, 5I); stigmatic clefts absent, each with a single stigmatic spine (Figs 2D, 3A, 4D, 5I). Venter with multilocular discpores each with 10 loculi (Figs 3G, 5E); tubular ducts of 1 or 2 types present over entire surface (Figs 3H, 5G); antenna 7 or 8 segmented (Figs 2C, 4C); legs without tibio-tarsal articulatory scleroses (Fig. 3F) (Williams & Watson 1990; Hodgson 1994).

Remarks. Drepanococcus contains 4 species, mostly distributed on South-East Asia (García Morales et al., 2016). Adult females of the genus are completely covered with a test of granular glassy wax in life. In slidemounted material, this genus is easily recognized by the single and long stigmatic spine opposite each spiracle (Williams & Watson 1990).
