Phortica setitabula Chen and Gao View in CoL , sp. nov.

( Figure 8 View Figure 8 )

Diagnosis

Additional plate between cerci very large, more than tenth sternite ( Figure 8B View Figure 8 ); paramere subapically with acute process ( Figure 8C View Figure 8 ); branch of aedeagal basal bridge with two slender processes basally and two small, triangular projections laterally ( Figure 8C View Figure 8 ).

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

Description

Head. Frons nearly entirely dark brown. Arista basally with dorsal branches. Face entirely orange-brown. Gena black. Postgena brown.

Thorax. Anepisternum with a few setulae. Scutellum pale yellow, with a grey patch.

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

Abdomen. Third and fifth tergites with broad, brown-black bands along posterior margins, sublaterally with one pair of yellow patches.

Male terminalia. Epandrium lacking pubescence anteroventrally, with ten setae near the dorsal to posterior margins ( Figure 8A View Figure 8 ). Surstylus with dense, long setae, and pubescence, and about 18–20 apically rounded prensisetae ( Figure 8A View Figure 8 ). Paramere lacking pubescence, with one sensillum and two pointed teeth apically ( Figure 8C View Figure 8 ). Aedeagal median rod symmetrically expanded subapically ( Figure 8C View Figure 8 ).

Measurements. BL 54.20 mm (3 „ paratypes: 3.34–4.40); ThL 51.75 mm (1.40–2.10); WL 53.80 mm (3.27–4.10); WW 51.50 mm (1.33–1.80).

Indices. arb55/0, adf51.60 (1.40–1.60), flw51.60 (1.50–1.60), FW/HW50.40 (0.40), ch/ o50.07 (0.07–0.08), prorb51.20 (1.00–1.20), rcorb50.45 (0.40–0.50), vb50.35 (0.35– 0.50), dcl50.50 (0.50–0.55), presctl50.75 (0.65–0.80), sctl51.10 (1.00–1.10), sterno50.95 (0.90–0.95), orbito51.60 (1.30–1.60), dcp50.25 (0.25–0.30), sctlp51.10 (1.10), C52.40 (2.50–2.81), 4c51.59 (1.30–1.60), 4v53.14 (2.86–3.70), 5x51.00 (0.71– 0.80), ac53.50 (2.60–3.00), M50.68 (0.60–0.70), C3F50.76 (0.69–0.71).

Holotype: „, China: Yixiang, Simao , Yunnan, 1400 m alt., 5 December 2000, J.-J. Gao ( KIZ). Paratypes: 3 „, same data as the holotype ( KIZ, SCAU, and SEHU).

Remarks

This species is similar to P. bipartita ( Toda and Peng, 1992) in the anepisternum with setulae and the aedeagal median rod much expanded apically. In P. bipartita the arista has three ventral branches, and the paramere is strongly sclerotized and deeply bifurcated: the primary one with two sharp projections apically and three to four sensilla subapically; secondary one slender.
