Description

Holotype, ♀, length of body 4.6 mm, of fore wing 3.9 mm.

Head. Antennal segments 35, length of third flagellomere 1.2 times fourth flagellomere, length of third and fourth flagellomere 3.0 and 2.5 times their width, respectively; maxillary palp 0.8 times height of head; malar space 1.5 times as long as basal width of mandible; in dorsal view length of eye 2.1 times temple (Fig. 10 View Figure 10 ); face distinctly punctate (Fig. 11 View Figure 11 ); frons without medial ridge, smooth; vertex and temple smooth (Fig. 12 View Figure 12 ).

Mesosoma. Length of mesosoma 1.2 times its height; pronotum finely punctate dorso-posteriorly and posterior groove finely crenulate; area near lateral carina of mesoscutum crenulate; mesoscutum densely punctate and setose; notauli complete and narrowly crenulate; scutellar sulcus 0.5 times as long as scutellum with 3 carinae; scutellum without subposterior crest, shiny, sparsely punctate (Fig. 13 View Figure 13 ); precoxal sulcus weakly crenulate and narrow; mesopleuron below precoxal sulcus with sparse fine punctures; mesopleuron above precoxal sulcus mostly smooth, finely punctate anteriorly; metapleuron densely setose, spaced moderately punctate and ventrally rugose (Fig. 14 View Figure 14 ); propodeum reticulate-rugose (Fig. 13 View Figure 13 ).

Wings. Fore wing: second submarginal medium-sized and triangular; marginal cell narrow; vein SR 1 straight; r: 3 - SR + SR 1 = 3: 46 (Fig. 15 View Figure 15 ). Hind wing: vein M + CU 0.9 times as long as vein 1 - M (14: 16).

Legs. Length of hind femur, tibia and basitarsus 3.1, 5.5 and 8.5 times their width, respectively; hind femur (as remainder of legs) with short setae (Fig. 16 View Figure 16 ); length of outer and inner spur of middle tibia 0.4 and 0.6 times middle basitarsus, respectively; outer side of middle tibia with 12 pegs; length of outer and inner spur of hind tibia 0.3 and 0.5 times hind basitarsus, respectively; tarsal claws with lobe.

Metasoma. Length of first tergite 1.2 times its apical width; first tergite coarsely longitudinally striate; second tergite 1.15 times as long as third tergite, coarsely longitudinally striate with transverse groove; third tergite coarsely longitudinally striate in basal 0.7, smooth in apical 0.3; remainder of metasoma smooth (Fig. 17 View Figure 17 ); ovipositor sheath 0.6 times as long as fore wing.

Colour. Black; mandible, palpi, pronotum, mesoscutum, scutellum and mesopleuron orange-brown; head ventrally half, fore and middle legs brownish-yellow (but middle coxa, trochanter, trochantellus and femur partly dark brown); hind leg almost entirely dark brown; pterostigma dark brown; wing membrane subhyaline (Fig. 18 View Figure 18 ).

Diagnosis

This new species is very similar to L. romani ( Shestakov, 1940) , but differs in having the mesoscutum distinctly protruding forward; frons without a medial ridge; and length of mesosoma 1.2 times its height.

Etymology

From “ convexus ” (Latin for “ convex ”), because of the convex mesoscutum.

Distribution

China (Sichuan)

Unknown.
