Fig. 3A-N View Figure 3

Type materials.

Holotype: China • ♂; Guizhou Province, Panxian County, Banqiao Town; 25°44'N, 104°39'E; sweeping, 2 July 2011; Zhi-Hua Fan leg.; IEGU. Paratype: 1♂, same collection data as for holotype; IEGU.

Diagnosis.

The salient features of the new species include: vertex (Fig. 3A, C View Figure 3 ) at least three times as long as broad; frons (Fig. 3D View Figure 3 ) yellowish brown, with brown spots; aedeagus (Fig. 3K-N View Figure 3 ) in total with 3 processes; spinose process near apex of periandrium on right side (Fig. 3K View Figure 3 ) long, half wide at base, half thinner at end; left side (Fig. 3L View Figure 3 ) apical process of endosoma bifurcated, rami long, approximately equal length; a subapical spine, lateral margins curved.

Measurements.

Total length: male 7.23-7.65 mm (n = 2).

Description.

Coloration. General color dark brown (Fig. 3A, B View Figure 3 ). Vertex blackish brown. Eyes brown, ocelli yellowish. Frons yellowish brown, with brown spots, carinae lighter; rostrum blackish brown. Pronotum grayish to blackish brown with carinae yellowish or light brown. Mesonotum dark brown, carinae brown. Forewings semitranslucent, light brown, with several brown markings, stigma yellowish brown. Hindwings semitransparent. Abdomen dark brown.

Head and thorax. Vertex (Fig. 3A, C View Figure 3 ) narrow, 3.23 times longer than wide. Frons (Fig. 3D View Figure 3 ) with distinct median carina, longer in middle line than wide at widest portion (about 1.67:1). Clypeus (Fig. 3D View Figure 3 ) with distinct median and lateral carinae. Rostrum elongate, surpassing hind-coxae. Pronotum (Fig. 3C View Figure 3 ) wider than maximum width of head (including eyes) (1.60:1), lateral and median carinae present. Mesonotum (Fig. 3C View Figure 3 ) about 6.92 times longer than pronotum in midline, with 5 carinae, distal part of median carina blurry. Forewings (Fig. 3E View Figure 3 ) slender, longer than maximal width (3.01:1), with 12 apical and 6 subapical cells; fork ScP+R distal to fork CuA1+CuA2; RP 3 branches, MP1+2 3 branches, and MP3+4 2 branches.

Male terminalia. Pygofer (Fig. 3F, H View Figure 3 ) symmetrical, in lateral view, lateral lobes triangularly extended caudally; in ventral view, dorsal margin concave and U-shaped, middle part narrow. Medioventral process triangular in ventral view. Anal segment (Fig. 3F, I, J View Figure 3 ) tubular, asymmetrical, widened towards apex in left side view; in right side view, left ventral margin convex and right ventral margin excavated near apex; 1.68 times longer than wide in dorsal view; anal style finger-like, beyond anal tube. Aedeagus (Fig. 3K-N View Figure 3 ) in total with 3 processes; spinose process near apex of periandrium on right side long, half wide at base, half thinner at end, directed cephalically, more than 1/2 length of periandrium; left side apical process of endosoma bifurcated, rami long, approximately equal length, dorsal ramus directed cephalad, ventral ramus directed ventrocephalad; a subapical spine, lateral margins curved, curved dorsad, apical margin rounded. Gonostyli (Fig. 3F-H View Figure 3 ) slender, curved apically, tapering into a process, constricted for about ¾ its length, T-shaped in ventral view.

Distribution.

China (Guizhou) (Fig. 1 View Figure 1 ).

Etymology.

The new species is named after its the county in which it was collected.

Remarks.

This species is similar to Oecleopsis laminatus Zhi & Chen, 2018, but differs from the latter in: (1) spinose process near apex of periandrium long, half wide at the base, ½ thinner at end (spinose process near apex of periandrium long, smoothly tapering at the end in O. laminatus ); (2) apical process of endosoma bifurcated at base (apical process of endosoma bifurcated at apex in O. laminatus ); (3) left side near apex of endosoma with a spiniform process, curved dorsad (left side near apex of endosoma with a large laminal process, directed cephalad in O. laminatus ).
