Diagnosis.

P. carinata appears most similar to P. stimula especially in the expanded distal part of the telopodite, of which the distal part is downturned and crossing with the curved process of the solenomere, differing in the shape of the distal process, showing as a subrectangular plate in Paracortina carinata vs dome-shaped in P. stimula . Both species could be recognised also by the body colouration which is dark brown in P. carinata and yellow in P. stimula .

Descriptive notes.

(based on Wang and Zhang 1993) Holotype 42 mm long, 2.5 mm wide, 60 podous + 2 apodous PTs, with a dark brown colour.

Gonopods. Each gonopod with two asymmetrical prefemoroidal processes (pf1, pf2), with pf1 larger and more setose than pf2, a stout and falcate coxal process, reaching 2/3rd of the telopodite; telopodite (T) with a uniformly broad stem, distal part abruptly expanding antero-posteriad and showing in a lateral view ( Wang and Zhang 1993, fig. 29) a subrectangular plate with an irregular apical margin, and a notch on the anteromesal side separating the main branch from a curved narrow process pointing distad, terminating in a slender branch bifurcated in solenomere (s) and parasolenomere (ps).

Distribution.

Shangrila (= Zhong Dian) County, Yunnan, China (Fig. 28 ).

Comments.

Known only from its original description ( Wang and Zhang 1993).
