( Figs. 1 View FIGURE 1 , 2 View FIGURE 2 )

Description. Body length (including tegmina): male 6.2 mm, female 6.6–7.0 mm.

Body color fuscous. Fore margin of crown ( Fig. 1 View FIGURE 1 , A, B, D) with two irregular black patches each side of midline, middle and hind region with dense and scattered dark brown irrorations, extended to near base of pronotum. Face ( Fig. 1 View FIGURE 1 , C) with small yellowish brown mottling, upper part black, lower part black brown. Eyes ( Fig. 1 View FIGURE 1 , A, B, D) with dark brown spots. Middle and hind region of pronotum ( Fig. 1 View FIGURE 1 , A, B, D) with dense dark brown striations. Basal triangle of scutellum ( Fig. 1 View FIGURE 1 , A, B) with a large dark yellowish brown oblate spot, medial area with a longitudinal dark brown striated band. Forewing ( Fig. 1 View FIGURE 1 , A, E) marked with dense dark brown vermiform irrorations and veins yellowish brown, subcosta with four large dark brown patches arising from near medial to apical region. Legs ( Fig. 1 View FIGURE 1 , C, E, F) dark brown.

Head ( Fig. 1 View FIGURE 1 , A, B, D) broader than pronotum. Crown ( Fig. 1 View FIGURE 1 , A, B) elongate, anterior margin rounded and produced, conspicuously concave medially, posteriorly elevated, median length of vertex longer than next to eyes, coronal suture distinct, extended to near vertex 2/3. Face ( Fig. 1 View FIGURE 1 , C) with frontoclypeus concave sub-basally and lateral margin slightly concave; lateral frontal sutures ( Fig. 1 View FIGURE 1 , C) extending to corresponding ocelli. Pronotum ( Fig. 1 View FIGURE 1 , A, B) with side margin short, carinate, posterior margin slightly concave. Scutellum ( Fig. 1 View FIGURE 1 , A, B) triangular, scutoscutellar sulcus distinct. Forewing ( Fig. 1 View FIGURE 1 , A, E) with appendix narrow. Fore femur with anteromedial (AM1) row setae enlarged, intercalary (IC) row with about 13 fine long setae.

Anterior margin of male pygofer ( Fig. 2 View FIGURE 2 , J, K) with a pair of large triangular apodemes. Pygofer side sharply constricted apically with several fine setae, ventroposterior process with rough wrinkles arising from middle to distal region, constricted and narrow subapically and pointed apically, ventrolateral margin with an inverted tooth at apex. Valve semi-circular. Subgenital plate ( Fig. 2 View FIGURE 2 , N) short, broad proximally and tapering distally, lateral margin without macrosetae and with several fine and long microsetae. Style ( Fig. 2 View FIGURE 2 , O) narrow and long, apical process digitate, with a small sclerotized tooth-like process subapically on lateral surface, lateral lobe absent. Connective ( Fig. 2 View FIGURE 2 , Q, R) arms robust and short, far from each other. Aedeagal shaft ( Fig. 2 View FIGURE 2 , P, Q, R) curved dorsad and tapering distally, with small dense dentate processes or spines from nearly medial to apical region, robust and foot-like in lateral view; preatrium slightly longish, apex with a pair of small triangular lateral projections extended ventrad, articulated with connective stem; dorsal apodeme well developed, shorter than the length of shaft, strikingly bifurcated apically extended laterad; gonopore ( Fig. 2 View FIGURE 2 , R) large, nearly median to apex on ventral surface. Anal tube ( Fig. 2 View FIGURE 2 , L, M) long and cylindrical in lateral view, broad basally, sclerotized laterally and dorsally.

Female: Hind margin of seventh sternite ( Fig. 1 View FIGURE 1 , I) with V-shaped notch in middle and lateral margin prominently produced.

Material examined. Holotype: ♁, Zambia: Copperbelt Prov., ~ 12 km SSE of Kitwe, Greystone Farm , 12º55'03.8″S, 28º15'52.6″E, 1247 m, 11.XI.2007, Hg-vapor light, ZA-09, Coll. J.N. Zahniser ( INHS) GoogleMaps . Paratypes: 3♀, same data as the holotype ( INHS) GoogleMaps .

Etymology. This new specific epithet originates from the Latin word “picea” referring to the black face.

Remarks. This new species can be distinguished from other species of this genus by the following unique characters: style apical process with a small subapical tooth-like process on lateral surface; aedeagal shaft curved dorsad, with small dense spines from nearly medial to apical region.
