Type material.

Holotype, ♂ (RMNH), "C. Vietnam: Thua Thien Hué, Phong Dién N.R., n[ea]r base-camp, 50-100 m, 25.iii.2001, C. van Achterberg, RMNH’01”.

Diagnosis.

The new species is close to the Palaearctic Zelodia varipes (van Achterberg & Maetô). The latter species differs by having the clypeus dorsally at lower level of eyes, hind femur finely sculptured, the pleural sulcus with shorter and more crenulae and rather narrow, the submedial cell of the fore wing largely glabrous and the mesoscutum dark brown.

The new species is similar to Zelodia quadrifossulata (Enderlein), but that species has the mesosoma completely yellowish-brown, OOL 1.6-2.0 times as long as POL and second tergite more or less yellowish or brown.

Description.

Holotype, ♂, length of body 6.0 mm, of fore wing 5.7 mm.

Head.

Antennal segments 39, densely bristly setose, setose length of third segment 1.2 times fourth segment, length of third, fourth and penultimate segments 3.0, 2.4 and 1.5 times their width, respectively; penultimate segment half as long as apical segment (including spine); scapus cylindrical, 2.1 times as long as wide; length of maxillary palp 0.6 times height of head; length of malar space twice basal with of mandible and 0.4 times height of head (Figs 464, 467); in dorsal view eye twice as long as temple (Fig. 466), in lateral view temple 0.55 times width of eye (Fig. 467), temple smooth, except for some fine punctures; ocelli comparatively small (Fig. 466), POL:OD:OOL = 6:5:9; face shiny and rather sparsely moderately punctate, no rugae medially; clypeus dorsally distinctly above lower level of eyes (Fig. 465); frons shiny, smooth, hardly depressed medially and without lateral carinae; vertex shiny and very sparsely finely punctate; pair of crests between antennal sockets weak, convergent; occipital flange large, its ventral margin convex (Fig. 464).

Mesosoma.

Length of mesosoma 1.3 times its height; subpronope medium-sized, rather shallow; side of pronotum smooth, but with some punctures dorsally and crenulate posteriorly; area near lateral carina of mesoscutum distinctly crenulate; mesoscutum distinctly rather densely punctate and shiny, but sparsely punctate posteriorly; middle lobe of mesoscutum slightly grooved; notauli rather narrow, rather deep and distinctly crenulate (Fig. 460); scutellar sulcus with 3 carinae and 0.8 times as long as dorsal face of scutellum; scutellum weakly convex and coarsely punctate; subposterior crest strong and curved (Fig. 460); precoxal sulcus distinct, nearly complete, anteriorly with some coarse sublongitudinal rugae, remainder moderately crenulate (Fig. 459); mesopleuron largely rather coarsely punctate with interspaces wider than punctures; pleural sulcus wide and coarsely crenulate, with 7, mostly coarse crenulae; metapleuron with long silvery setae, upper densely and coarsely punctate, lower half coarsely vermiculate rugose; propodeum coarsely areolate, without medial carina basally and with weak anterior transverse carina (Fig. 460); propodeal spiracle large, elliptical, 2.5 times as long as wide; distance between spiracle and lateral carina about equal to width of spiracle.

Wings.

Fore wing: second submarginal cell narrow anteriorly, without ramellus (Fig. 461); r:3-SR:SR1= 5:4:102; 2-SR:3-SR:r-m = 17:4:16; submedial cell sparsely but distinctly setose. Hind wing: M+CU 0.6 times as long as 1-M; surroundings of cu-a glabrous except for a few setae.

Legs.

Hind coxa rather pimply dorsally, basally punctate but largely smooth; length of hind femur, tibia and basitarsus 3.9, 6.7 and 7.6 times their width, respectively; hind femur coarsely punctate, ventrally coarsely rugose and with rather short setae (Fig. 463); outer side of apex of hind tibia with two pegs; fore tarsus slender and with long setae (as in other species); outer and inner spur of middle tibia 0.55 and 0.95 times middle basitarsus, respectively; outer and inner spur of hind tibia 0.4 and 0.7 times hind basitarsus.

Metasoma.

First tergite rather slender, smooth, slightly widened apically (Fig. 463); length of first tergite 1.9 times its apical width; second tergite rectangular and 0.8 times as long as wide apically, smooth with one transverse row of setae subapically; second metasomal suture obsolescent (Fig. 463).

Colour.

Dark brown (including antenna, pterostigma and veins); wing membrane slightly infuscate and without a distinct stigmal spot; head, pronotum and mesoscutum yellowish-brown; first tergite ivory; fore and middle legs (middle coxa, trochanter, trochantellus and base of middle femur dark brown and telotarsi slightly infuscate) brownish-yellow.

Distribution.

C Vietnam: Thua Thieu Hué. Further known from China (Fujian).

Biology.

Unknown.

Etymology.

From “micro” (Greek for “small”), and “ocellus” (Latin for "small eye"), because of the small ocelli.
