Apsiphortica multiclavata Chen and Toda , sp. nov.

( Figures 10, 11 )

Diagnosis

Epandrium without strong setae on ventral margin ( Figure 10 ); aedeagal outer membrane with 13 elongated, tentacle-like, sclerotized pieces ( Figure 11 ).

Description

Some characters commonly seen in A. longiciliata are not referred to in the following description.

Head. Eye dark brown. Frons and ocellar triangle nearly black. Clypeus dark brown. Palpus yellow-brown.

Thorax. Yellow, with brown patches on pleura. Scutellum brown.

Abdomen. Tergites yellow, each with black caudal band not reaching to lateral margins. Male terminalia. Epandrium pubescent, with 15–16 setae near posterior margin ( Figure 10 ). Surstylus basally broad, ventro-apically narrowing and curved posteriod, with setulae in two patches on dorso-apical corner and ventro-apical portion ( Figure 10 ). Paramere articulated with base of aedeagus, extending ventrad, slightly longer and paler than tentacle-like pieces on aedeagal outer membrane, apically slightly dilated and serrated ( Figure 11 ). Gonopods anteriorly with a pair of strongly sclerotized, divergent processes ( Figure 11 ). Aedeagal median rod basally fused to aedeagal apodeme ( Figure 11 ). Ventral branches of aedeagal apodeme very small, apically knobbed and strongly sclerotized, but not fused to each other ( Figure 11 ).

Measurements. BL 53.42 mm in the holotype (3.88 in 1 (male) paratype); ThL 51.72 mm (1.68); WL 52.60 mm (2.80); WW 51.28 mm (1.20).
