Protosticta taipokauensis (White-banded shadowdamsel)

Habitat: larvae found under rocks in clean and slow flowing mountain forest streams e.g. Tai Po Kau Forest Stream

General appearance: body large sized, up to 25mm long; head heart-shaped with a pair of bulbous eyes, but lacking spines along anteroventral margin of eye (cf. Philoganga vetusta); tarsi 3 segmented (cf. 2 segmented in Agriomorpha fusca); wing sheath up to 6th abdominal segment; three large caudal gills with a pointed end, but without lateral abdominal gills (cf. Euphaea); lateral gills appear more massive than the median one & be somewhat semi-circle in cross section.

* No fenestrum in the cleft median lobe of labium & presence of minute setae on the mentum & mandible (could these features be distinguished from Depanosticata hongkongensis?!)
