Figs 27–28 View FIGURE 27 View FIGURE 28

Type material. Holotype. ♀, China, Yunnan Prov., Cheli , 580m, 14.IV.1957, Pu Fuji, No. IOZ(E)1964603 ( IZ- CAS).

Diagnosis. This new species is very similar to Ectemnoplax peruliventris Enderlein, 1920 , but can be separated from the latter by the following characters: mesosoma largely black (largely reddish yellow in E. peruliventris ); antero-lateral areas of third and fourth metasomal tergites black (whitish yellow); fore wing cu-a interstitial (slightly postfurcal).

Description. Holotype, ♀, length of body 4.7 mm, of fore wing 4.9 mm, of ovipositor sheath 0.4 mm.

Head. Antenna with 40 antennomeres; apical flagellomere with a short spine, 2.0 × longer than its maximum width ( Fig. 28l View FIGURE 28 ); penultimate flagellomere 1.4 × longer than its maximum width, and 0.8 × as long as apical flagel- lomere; median flagellomeres 1.3 × longer than its width; first flagellomere 1.4 × longer than its width, and 1.2 and 1.3 × longer than second and third, respectively, the latter being 1.3 × longer than wide; malar suture with dense short setae and superficially sculptured; clypeus height: inter-tentorial distance: tentorio-ocular distance = 3: 13: 6; clypeus with sparse long setae; eye weakly emarginate ( Fig. 28g View FIGURE 28 ); face weakly rugose and densely setose ( Fig. 28g View FIGURE 28 ); eye height: shortest distance between eyes: head width = 19: 18: 47; frons densely setose, weakly concave behind antennal sockets, with a strong median groove ( Fig. 28h View FIGURE 28 ); vertex smooth, with dense short setae; shortest distance between posterior ocelli: shortest diameter of elliptical posterior ocellus: shortest distance between posterior ocellus and eye = 3: 3: 7; temples densely setose, and strongly narrowed behind eyes ( Fig. 28h View FIGURE 28 ).

Mesosoma. Length of mesosoma 1.2 × its height ( Fig. 28c View FIGURE 28 ); notauli complete and relatively deeply impressed ( Fig. 28d View FIGURE 28 ); mesoscutum densely short setose ( Fig. 28d View FIGURE 28 ); scutellar sulcus deep, narrow and with crenulae ( Fig. 28d View FIGURE 28 ); scutellum weakly convex, with dense short setae; metanotum moderately convex medially, with a short carina anteriorly ( Fig. 28d View FIGURE 28 ); propodeum largely smooth, without medio-longitudinal carina or groove, and densely short setose ( Fig. 28d View FIGURE 28 ).

Wings. Fore wing ( Fig. 28a View FIGURE 28 ): SR1: 3-SR: r = 34: 19: 6; 1-SR+M more or less straight, 1.7 × longer than 1-M; 2-SR: 3-SR: r-m = 10: 19: 8; cu-a interstitial. Hind wing ( Fig. 28b View FIGURE 28 ): 1r-m more or less straight; SC+R1: 2-SC+R: 1r-m = 25: 10: 7.

Legs. Length of fore femur: tibia: tarsus = 31: 35: 42; length of hind femur: tibia: basitarsus = 38: 55: 22; length of femur, tibia and basitarsus of hind leg 3.2, 7.9 and 5.5 × their maximum width, respectively; hind tibial spurs 0.36 and 0.41 × as long as hind basitarsus.

Metasoma. Length of first tergite equal to its apical width, smooth medio-basally, median area distinctly convex posteriorly, reticulate-rugose ( Fig. 28j View FIGURE 28 ); first tergite without medio-longitudinal carina, lateral areas very narrow ( Fig. 28j View FIGURE 28 ); length of second tergite 0.6 × its maximum width; medio-basal area of second tergite small and smooth, attached to medio-longitudinal carina, carina absent near posterior margin of second tergite; oblique anterior grooves relatively long and narrow; second tergite largely reticulate-rugose but medio-basal area smooth ( Fig. 28e View FIGURE 28 ); second suture deep, crenulate, more or less straight medially ( Fig. 28e View FIGURE 28 ); antero-lateral areas of third and fourth tergites small; third–fifth tergites reticulate-rugose; posterior margin of fifth tergite usually narrowly emarginate medially ( Fig. 28k View FIGURE 28 ); sixth and seventh tergites retracted; ovipositor sheath 0.1 × as long as fore wing.

Colour. Largely black ( Fig. 27 View FIGURE 27 ); mandible (but apically black) yellow ( Fig. 28g View FIGURE 28 ); pronotum and propleuron laterally infuscate ( Fig. 28c View FIGURE 28 ); fore leg largely yellow, but claws dark brown, middle and hind legs dark brown ( Fig. 28f View FIGURE 28 ); second metasomal tergite medially black, laterally whitish yellow ( Fig. 28e View FIGURE 28 ); third and fourth tergites whitish yellow, but anteriorly, anterio-laterally, medially (but posteriorly whitish yellow) black ( Fig. 28e View FIGURE 28 ); fifth tergite largely whitish yellow but anteriorly black ( Fig. 28e View FIGURE 28 ); wing membrane infuscate, pterostigma and veins dark brown ( Figs 28a, 28b View FIGURE 28 ).

Biology. Unknown.

Distribution. China (Yunnan).

Etymology. Named after the pair of black spots of the third and fourth metasomal tergites: “bi” is Latin for “two” and “maculosus” is Latin for “spotted”.
