Szeptyckitheca formosana (Yosii, 1965)

Sphyrotheca formosana Yosii, 1965: 49.

Diagnosis.

Yellowish ground, antennae diffusely pigmented, head almost pale, large abdomen laterally purplish, dorsally pale. Ant. IV with nine or ten subsegments. Head vertex with a total of 15 large spines, three of them unpaired; unpaired chaeta A1 present. Ungues with a single inner tooth, with tunica and without pseudonychia; unguiculus I with the internal tooth; unguiculus III filament thin and not reaching the tip of the unguis III. Large abdomen without capitate chaetae. Female’s subanal appendage long (surpassing the ventral anal valves), blunt, apically serrated on its external face. Dens ventral chaetotaxy formula from the apex to the base as: 3,1 … 1, dorsal chaetotaxy with 15 chaetae; mucronal notch prominent (adapted from Yosii 1965).

Remarks.

Like S. boneti , S. formosana was apparently revised by Betsch ( Betsch 1980; Betsch and Weiner 2009). Nevertheless, many important data on its morphology are still lacking (see Table 2 ), and it is in need of redescription.

Habitat.

Unknown.

Known distribution.
