Zelodia anginota sp. n. Figs 418-426

Type material.

Holotype, ♀ (RMNH), "S. Vietnam: Dak Lak, Chu Yang Sin N.P., n[ea]r dam, 744-900 m, 1-10.vi.2007, Mal[aise] trap, C. v. Achterberg & R. de Vries, RMNH’07”. Paratype: 1 ♀ (IEBR), Aga. 187, "NE Vietnam: Phu Tho, Xuan Son N.P., forest, 10.v.2005, P.Th. Nhi".

Diagnosis.

The new species is close to Zelodia longidorsata (Bhat & Gupta, 1977), but differs by having the propodeal spiracle 3 times as long as wide ( Zelodia longidorsata : twice); the first tergite without a dorso-lateral carina above the spiracle and the glymma smooth (longidorsata: dorso-lateral carina present above spiracle and glymma sculptured); the second tergite as long as wide apically (longidorsata: 1.5 times longer than wide) and the head and mesosoma black except for the reddish yellow mesonotum (longidorsata: head and mesosoma yellowish-brown).

Description.

Holotype, ♀, length of body 6.3 mm, of fore wing 6.4 mm.

Head.

Antennal segments 42, length of third segment 1.2 times fourth segment, length of third, fourth and penultimate segments 2.5, 2.1 and 1.7 times their width, respectively; penultimate segment 0.6 times as long as apical segment; antenna densely setose; scapus nearly cylindrical, 2.2 times as long as wide; length of maxillary palp 0.7 times height of head; malar space 1.5 times as long as basal width of mandible, 0.3 times height of eye and 0.2 times as long as height of head in lateral view (Fig. 426); in dorsal view eye twice as long as temple (Fig. 425); POL:OD:OOL = 9:8:13; face shiny, punctate, rugose-punctate medially; frons shiny, smooth and without lateral carinae; vertex shiny with sparse fine punctures; pair of crests between antennal sockets strong, convergent; occipital flange large, its ventral margin convex (Fig. 426).

Mesosoma.

Length of mesosoma 1.3 times its height; subpronope medium-sized, shallow; side of pronotum smooth and with sparse fine punctures posteriorly; area near lateral carina of mesoscutum smooth; mesoscutum with distinct punctures anteriorly, shiny and sparsely punctate posteriorly; middle lobe of mesoscutum slightly grooved; notauli narrow, rather deep and punctate, fused posteriorly, forming wide shallow groove (Fig. 421); scutellar sulcus rather long, with 3 carinae and 0.8 times as long as dorsal part of scutellum; scutellum convex, distinctly narrowed posteriorly, rugose-punctate; subposterior crest long and curved (Fig. 421); precoxal sulcus shallow, widely crenulate (Fig. 419); mesopleuron below sulcus largely punctate, and above sulcus with sparse fine punctures; metapleuron with long, dense setae, upper side areolate-rugose, lower side with strong rugae; propodeum setose basally with large areola and costulae, without a medial carina basally and with a weak anterior transverse carina (Fig. 421); propodeal spiracle large, elliptical, 3.0 times as long as wide; distance between spiracle and lateral carina as long as width of spiracle.

Wings.

Fore wing: second submarginal cell narrow anteriorly, without ramellus (Fig. 422); r:3-SR:SR1= 6:6:112; 2-SR:3-SR:r-m = 17:6:15. Hind wing: M+CU 0.5 times as long as 1-M (22:41); surroundings of cu-a setose.

Legs.

Length of hind femur, tibia and basitarsus 4.3, 6.5 and 11.3 times their width, respectively; outer side of hind coxa areolate-punctate; hind femur (as remainder of legs) with long and dense setosity (Fig. 420); outer side of apex of hind tibia with two pegs, and lower peg twice as long as upper peg; fore tarsus slender and with long setae; length of outer and inner spur of middle tibia 0.5 and 0.9 times middle basitarsus, respectively; length of outer and inner spur of hind tibia 0.4 and 0.7 times hind basitarsus.

Metasoma.

First tergite long, smooth, parallel-sided (Fig. 423); length of first tergite 3.6 times its apical width; second tergite rectangular and as long as wide apically, smooth with three transverse rows of setae apically; second metasomal suture absent (Fig. 423); ovipositor sheath 0.4 times as long as hind basitarsus.

Colour.

Black; mesonotum and mesopleuron reddish brown, but mesopleuron black posteriorly; fore and middle legs dark brown, but fore and middle tarsi whitish-yellow; first-third metasomal sternites white; pterostigma dark brown; wing membrane slightly infuscate, without stigmal spot.

Variation.

Length of body 6.3-7.3 mm; of fore wing 6.4-7.6 mm; antennal segments 42 (2); POL as long as OD or slightly larger; length of malar space 1.4-1.5 times basal width of mandible; first tergite slightly widened apically or parallel-sided, 3.1-3.6 times longer than wide apically.

Distribution.

NE Vietnam: Phu Tho and S Vietnam: Dak Lak.

Biology.

Unknown.

Etymology.

From “ango” (Latin for "pressed together") and “notos” (Greek for “back”), because of the narrow first metasomal tergite.
