Phortica latipenis Chen and Gao , sp. nov.

( Figure 7 )

Diagnosis

Secondary process of paramere larger than primary process, with a spine-shaped projection apically ( Figure 7C ); branch of aedeagal basal bridge strong, tripartite ( Figure 7C ).

Some characters commonly seen in P. uncinata sp. nov. are not referred to in the following description.

Description

Head. Frons brown. Arista basally with dorsal branches. Face brown. Gena black. Postgena brown.

Thorax. Pleura nearly entirely black. Anepisternum with several setulae.

Legs. Mid tibia subapically with two longer setae on anterior surface.

Abdomen. Abdominal third and fifth tergites with medially and sublaterally interrupted, broad, brown-black bands along posterior margins.

Male terminalia. Epandrium lacking pubescence anteroventrally, with eight setae near dorsal to posterior margins ( Figure 7A ). Surstylus with pubescence and dense setae, and about 15–17 apically round prensisetae ( Figure 7A ). Vertical process of gonopod slightly narrowed and sclerotized apically ( Figure 7C ). Paramere submedially pubescent and much expanded, with two processes apically: primary process with one sensillum and three small teeth apically ( Figure 7C ); aedeagal median rod asymmetrically expanded subapically ( Figure 7C ).

Measurements. BL53.00 mm; ThL 51.25 mm; WL 52.70 mm; WW 51.25 mm.

Holotype: „, Yunnan: Simao, Yixiang , 1400 m alt., 5 December 2000, J.-J. Gao ( KIZ).

Remarks

This species is similar to P. eparmata ( Okada, 1977) from Taiwan in the shape of the aedeagal median rod, and having the anepisternum with setulae, but can be distinguished from the latter species by the arista and the shape of the paramere (in P. eparmata : arista with five dorsal and one ventral branches, and paramere deeply concaved submedially).
