Material examined.
Holotype: female, "W Sumatra Padang Panjang XII.2003 St. Jakl leg." [ Indonesia, West Sumatra Prov., City of Padang Panjang ] [OLL].
Diagnosis.
The female of this new species is unique among congeners of Deuteragenia in having bifid tarsal claws (Fig. 2E View Figure 2 ). Other characters of importance are: propodeum medial and posterior portion with coarse transverse rugae; clypeus anterior rim smooth and polished, not depressed, and not differentiated from dorsal portion (Fig. 2A View Figure 2 ); head and mesosoma mostly without setae; T1 petiolate basally (Fig. 2D View Figure 2 ); F2-F10 pale ventrally; legs partially brown (Fig. 1 View Figure 1 ). The male is unknown.
Description.
Female, holotype (Figs 1 View Figure 1 , 2 View Figure 2 ). Length: body 8.4 mm, fore wing 7.4 mm. Head width 1.21 times its height; MID 0.51 times head width in frontal view (Fig. 2A View Figure 2 ). Ocelli large, well raised; ocellar triangle slightly acute-angled; POD: OOD = 0.87 (Fig. 2C View Figure 2 ). Head in frontal view with vertex barely produced above dorsal eye margin (Fig. 2A View Figure 2 ). Posterior margin of vertex in dorsal view hardly concave (Fig. 2C View Figure 2 ). Head with frons almost flat in lateral view. Gena in profile well developed (Fig. 2B View Figure 2 ). Malar space very short. Clypeus moderately convex, its width 2.6 times its height, and 1.0 times LID; anterior margin straight, not depressed and not differentiated from dorsal portion; anterolateral corner rounded (Fig. 2A View Figure 2 ). Labrum not exposed. Bristles of maxillary cardo hard and long, reaching mandible ventral face. Antenna elongated; flagellomeres cylindrical; ratio of scape, pedicel and flagellomeres length (on dorsal side) 25: 8: 39: 25: 20: 17: 17: 17: 15: 15: 14: 16; scape length 0.8 times UID; F1 length 5.0 times its maximum width (in dorsal view), and 1.27 times UID; apical flagellomere pointed apically.
Pronotum length 0.42 times its maximum width in dorsal view; anterior face not differentiated from dorsum; posterior margin moderately rounded (Fig. 1B View Figure 1 ). Dorsum of mesoscutum hardly convex. Dorsum of mesoscutellum and metanotum slightly convex like dorsum of propodeum in lateral view. Metapostnotum noticeably depressed, barely arcuately emarginated postero-medially, its length 0.15 times metanotum length medially. Propodeum somewhat elongated, its length 1.05 times its maximum width in dorsal view; dorsum and posterior face not differentiated from each other and evenly convex (Fig. 2D View Figure 2 ).
All femora without spines. Protibia ventral face apically with few short spines. Meso- and metatibia dorsal and outer-lateral face with scattered short spines. Tarsomeres 1-3 of all legs with very short spines ventrally; tarsomeres 4 and 5 of all legs without spines ventrally. Tarsal claws of all legs symmetrical and bifid; inner tooth as long as apical one, very broad at base, and narrowing apically, with pointed apex; outer margins of inner and apical teeth parallel (Fig. 2E View Figure 2 ).
Fore wing (Fig. 2F View Figure 2 ) translucent, with subapical and subbasal brown fasciae. Pterostigma brown, its length 4.75 times its height (on inner distance), and 5.2 times Rs2. Second submarginal cell narrowed on vein Rs by 0.77 times its own length on vein M, receiving crossvein 1m-cu at basal 0.55. Third submarginal cell narrowed on vein Rs by 0.43 times its own length on vein M, receiving crossvein 2m-cu at basal 0.3. Crossvein 2rs-m slightly bent near M. Crossvein 3rs-m weakly arcuate. Crossvein cu-a straight, originating beyond separation of vein M+CuA. Vein M touching wing margin. Hind wing (Fig. 2G View Figure 2 ) translucent, with slightly brownish apical portion.
Metasoma with T1 distinctly petiolate (Fig. 2D View Figure 2 ).
Head, meso- and metasoma matt and punctate. Clypeus anterior rim smooth and polished, with other part densely punctate (Fig. 2A View Figure 2 ). Mandible apical portion polished. Frons finely and densely punctate, median line distinct. Metapostnotum polished, with indistinct transverse striae. Propodeum (Fig. 2D View Figure 2 ) anterior portion with dense and coarse merging punctures, its medial and posterior portions with coarse transverse rugae which somewhat arcuate posteriorly. Antenna and legs matt.
Body black (Figs 1 View Figure 1 , 2 View Figure 2 ). Antenna black, with F2-F10 pale ventrally. Mandible partially brown apically. Bristles of maxillary cardo brown. Legs black, with following brown: all coxae and trochanters, fore- and mesofemora, foretibia partially, metafemure except apical portion, all claws.
Body without setae except following: upper frons along inner orbits with one long setae; gena with short scattered setae; all coxae anterior face and pronotum with scattered short setae; propodeum postero-laterally with scattered gray short setae; T6 and S6 with long and dense pale setae. Body with sparse gray pubescence most intensive on propodeum postero-laterally.
Male is unknown.
Distribution.
Indonesia: West Sumatra.
Etymology.
The specific epithet is a pathronym honoring Prof. Arkady Lelej (FSC Biodiversity FEB RAS, Vladivostok, Russia), my scientific advisor and inspirer, on the occasion of his 75th birthday.
