description: Pseudognaptodon bidoupensis van Achterberg, sp. n.
Figs 1–11
Type material. Holotype, ♀ (RMNH), “S. Vietnam: Lam Dong, Bidoup Nuiba N.P., n[ea]r Da Lat, 1065–1700 m, Mal[aise] trap[s] 1–12, 11–19.x.2005, C. v. Achterberg & R. de Vries, RMNH’05”.
Diagnosis. Antenna of ♀ with approx. 20 antennomeres (Fig. 1); basal area of second tergite smooth, transverse and 0.10 × as long as combined second and third tergites (Fig. 5); vein SR1 of fore wing only basally curved (Fig. 2); eye in dorsal view twice as long as temple, temple roundly narrowed posteriorly (Fig. 8); vein 1-R1 1.2 × as long as pterostigma; vein 3-SR+SR1 of fore wing only basally distinctly curved; first and second metasomal tergites black dorsally and largely longitudinally rugose, except posteriorly; second metasomal suture distinct medially and crenulate; first tergite widened posteriorly, approx. 0.8 × longer than its apical width (Fig. 5); scutellar sulcus finely crenulate (Fig. 4); vertex smooth and shiny, frons granulate (Fig. 8).
Description. Holotype, ♀, length of fore wing 1.7 mm, and of body 1.8 mm.
Head. Antenna with 20 antennomeres, scapus shorter dorsally than ventrally, length of third antennomere 1.2 × fourth antennomere, third, fourth and penultimate antennomeres 4.3, 3.5 and 2.5 × as long as wide, respectively (Figs 10, 11); maxillary and labial palpi with 6 and 4 segments, respectively; length of maxillary palp 1.1 × height of head; temple smooth; hypostomal flange narrow (Fig. 9); eye twice as long as temple in dorsal view; temples roundly narrowed behind eyes (Fig. 8); OOL:diameter of posterior ocellus:POL = 33:13:18; vertex smooth, remotely setose and shiny; frons granulate, glabrous and shiny, without median groove (Fig. 8); face smooth and shiny, evenly convex (Fig. 7); clypeus nearly truncate medially and ventral rim thin, remainder moderately convex and smooth; hypoclypeal depression 0.5 × as wide as face and deep; malar suture absent; length of malar space 1.7 × basal width of mandible; mandible weakly convex medially, strongly narrowed and twisted apically.
Mesosoma. Length of mesosoma 1.3 × its height; pronotum nearly vertical anteriorly and antescutal depression absent; side of pronotum smooth, but oblique groove crenulate anteriorly; mesopleuron convex, shiny and smooth; precoxal sulcus absent; episternal scrobe present, linear (Fig. 1); mesosternal suture rather deep and smooth; notauli complete, narrow, smooth and posteriorly shallowly impressed, and in between no groove (Fig. 4), but antero-medially shallowly longitudinally impressed; mesoscutum strongly shiny, smooth, only antero-laterally and near notauli with some long setae; scutellar sulcus finely crenulate (Fig. 4); scutellum wide, slightly convex, smooth and shiny; metapleuron largely smooth; propodeum evenly convex, smooth and shiny (Fig. 4).
Wings. Fore wing: pterostigma triangular (Fig. 2); 1-M straight; 1-SR longer than wide; 1-SR+M present anteriorly; 1-R1 1.2 × longer than pterostigma; vein r emitted slightly basad of middle of pterostigma and slender; r:3-SR+SR1:2-SR = 3:46:13; vein SR1 only basally curved and remainder straight (Fig. 2); vein 2-M of fore wing as long as vein 2-SR (Fig. 2); m-cu slightly antefurcal; 1-CU1 and cu-a widened, subequal; 1-CU1:2-CU1 = 1:10; CU1b absent; basal and subbasal cells of fore wing similarly setose as other cells. Hind wing: M+CU:1-M:1r-m = 10:18:5; all cells equally densely setose; m-cu not indicated; 2-SC+R slightly widened (Fig. 2).
Legs. Hind coxa smooth; tarsal claws rather robust and simple; length of femur, tibia and basitarsus of hind leg 3.4, 6.2 and 5.7 × as long as their maximum width; hind tibial spurs 0.30 and 0.35 × as long as basitarsus.
Metasoma. First tergite 0.8 × longer than its apical width, gradually widened apically, convex, largely longitudinally rugose, shiny, dorsope absent, its dorsal carinae coarsely developed basally and protruding, strongly converging, posteriorly present (Fig. 5); first tergite laterally with medium-sized laterope in distinctly crenulate glymma; second and third tergites mainly longitudinally rugose, but basal area, second tergite posteriorly and apical half of third tergite smooth (Fig. 5); basal area of second tergite transverse, medium-sized, smooth and 0.1 × as long as combined second and third tergites; third tergite without oblique antero-lateral grooves, but with smooth areas (Fig. 5); second metasomal suture distinct medially and coarsely crenulate; epipleura of 2 nd– 3 rd tergites transparent (Fig. 1); remainder of metasoma smooth, except for finely crenulate transverse groove of fourth tergite; length of ovipositor sheath 0.10 × fore wing.
Colour. Black; palpi white; scapus, pedicellus, tegulae, metasoma ventrally and legs (but apex of hind basitarsus, remainder of hind tarsus and telotarsi infuscated or dark brown) pale yellowish; head (except dark brown medio-dorsal part), third and fourth antennal segments, fifth and sixth tergites brownish yellow (Fig. 1); metasoma pale brownish and whitish ventrally (Fig. 1); pterostigma and ovipositor sheath dark brown; as most veins of fore wing (except basally); wing membrane subhyaline.
Etymology. Named after its type locality in southern Vietnam.
Distribution. Vietnam. Collected in open montane forest at 1065–1700 m.
