Description

Female (Fig. 2 View Figure 2 ): length of body in lateral view 4.6 mm, length of antenna 5.0 mm and length of fore-wing 4.4 mm.

Colour. Body (Fig. 2 View Figure 2 ) entirely black; antenna dark brown; mandible brown.

Head. Antenna (Fig. 2 View Figure 2 B) 1.1 times longer than body in female, 35 - segmented. Fourth segment 0.8 times longer than third segment, 1.1 times longer than fifth segment. Width of face (Fig. 2 View Figure 2 E) 1.7 times its height from ventral rim of antennal sockets to upper margin of clypeus; face concave and one carina distinct medially; face with short setae; between eye and antennal socket concave and rugose. Eye in dorsal view 1.4 times longer than temple. Ocello-ocular line (OOL) 3.7 times longer than diameter of anterior ocellus; OOL: antero-posterior ocellar line (AOL): postero-ocellar line (POL) = 26: 7: 9. Stemmaticum concave and carina distinct. Mandible with three teeth and rugose (Fig. 2 View Figure 2 L); second tooth sharp and narrow, entirely reddish-brown, separated from first tooth; first tooth lobe-shaped. Clypeus 3.3 times longer than wide.

Mesosoma. Mesosoma 2.0 times longer than wide in dorsal view; 1.2 times longer than wide in lateral view. Mesosoma (Fig. 1 G) with line-shaped medio-posterior depression; notauli weakly reduced posteriorly; anterior part of mesosoma rugose and setose; scutellar sulcus with one carina. Pronotum glabrous and entirely smooth; anterior part of mesoscutum with setae. Scutellum with dense and posteriorly directed setae. Maximum length of propodeum (Fig. 2 View Figure 2 G) 0.5 times its width; apical part of propodeum entirely rugose, medio-longitudinal carina present; propodeum without areola; preco ⅹ al sulcus (Fig. 2 View Figure 2 F) weakly developed; mesopleuron 1.6 times longer than wide. Fore-wing (Fig. 2 View Figure 2 C) 2.1 times longer than wide; pterostigma robust, 3.2 times longer than wide; vein r of fore-wing 0.4 times as long as wide; vein 2 - SR: vein r: vein 3 - SR = 5: 1: 7; vein 2 – SR + M weakly sclerotised; vein SR 1 1.6 times longer than vein 3 - SR.

Leg. Hind co ⅹ a as long as hind trochanter; hind femur width 3.8 times median length in lateral view; 0.6 times as long as hind tibia, as long as tarsus. Arolium not longer than claw (1 L).

Metasoma. First tergite entirely rugose, widened posteriorly, 2.1 times longer than its apical width. Setose part of ovipositor sheath (Fig. 2 View Figure 2 I) 0.4 times as long as mesosoma, 0.4 times as long as hind tibia and with short setae.

Diagnosis

Differs from other species in the group of Mesocrina species by setose part of ovipositor sheath about as long as first tergite, 0.4 times as long as hind tibia (0.7–0.9 times in other species); anterior half of mesoscutum with few setae, without punctures.
