Head ( Figs 2, 3 View FIGURES 2–4 ) 1.7–1.9× (1.7×) as wide as long, polished and weakly coriaceous; occipital carina present; occiput smooth, with even and fine setae; postocciput polished; temple weakly convex; ocelli larger and lateral ocellus close to eye, POL/OD=0.3–0.6 (0.6), lateral ocellus almost touching eye; inner margins of eyes indented opposite antennal socket, weekly convergent ventrally; face 1.3–1.5× (1.3×) as wide as long; groove between face and clypeus week; clypeus 2.1–2.6× (2.2×) as wide as long, evenly punctate, with apical margin truncate and with 1 sparse row of setae, weakly convex in lateral view; antenna with 37–39 (38) flagellomeres, 1st flagellomere 1.2–1.3× (1.3×) as long as 2nd, which 2.9–3.4× (3.1×) as long as wide.

Mesosoma ( Fig. 4 View FIGURES 2–4 ) polished, smooth and evenly punctate; pronotum weakly costulate laterally; mesoscutum 1.2–1.4× (1.2×) as long as wide, with notaulus weak and extending to at least 1/3 length of mesoscutum; scutellum 1.1–1.4× (1.4×) as long as distance between lateral carinae at its base, with lateral carina fading out at around anterior 1/3 of scutellum; propodeum with weak trans-striae and faint sub-lateral crest, with pleural carina present and spiracle ovoid.

Fore wing ( Fig. 5 View FIGURES 5–6 ) 2.3–2.8× (2.8×) as long as wide; 3rs-m absent (areolet open); basal about 1/7 of Rs curved; 1cu-a antefurcal to M&RS by 0.2–0.3 (0.3) of 1cu-a length; subbasal cell without hairs except anterior margin; anal cell with a band of hairs. Hind wing ( Fig. 6 View FIGURES 5–6 ) with 4 or 5 distal hamuli, nervellar index 0.4–0.6 (0.5).

Fore tibial spur 0.3–0.5× (0.4×) as long as basitarsus, which 10.5–11.1× as long as wide; coxae weakly coriaceous; bristles on tibiae sparse, their sockets separated by more than the length of bristles; tarsal claws pectinate; fore tarsal claw with 16–20 (16–19) teeth; mid tarsal claw with 18–21 (20 or 21) teeth; hind tarsal claw normal, with 10–11 (10–11) teeth.

Metasoma polished, minutely and evenly punctate; 1st tergite 2.8–3.0× (2.9×) as long as apical width, 1.5× as long as 2nd; paramere ( Figs 7, 8 View FIGURES 7–9 ) 1.7–2.0× as long as wide, with a spine on subapical portion of dorsal margin; spine of paramere about twice as long as wide and parallel-sided with rounded apex; paramere rather weakly tapering toward rounded apex, width at apex of lamina volsellaris 1.4× as width at base of marginal spine; brace in shape of narrow band; pad produced dorso-basally; digitus with ventro- and dorso-apical corners pointed; aedeagus ( Fig. 9 View FIGURES 7–9 ) with penis valve slightly broadened toward apex and basal apodeme almost straight, broadened around middle and with dorsal margin convex.

Head yellow; mandible whitish or grayish yellow except teeth black; area around stipes and triangular marking on frons yellowish brown to brown in Taiwanese specimens; dorso-median portion of occiput brown in Taiwanese specimens; dorso-median portion of face and area dorsad of tentorial pits whitish; area around basal and apical margins of clypeus whitish; antenna reddish yellow, with apical flagellomeres paler. Mesosoma whitish yellow; mesoscutum brown with posterior 3/5 of median lobe paler except brown spot on posterior 1/2; scutellum, metanotum and dorsal surface of propodeum light brown to brown (light brown) with paler area along lateral carina of scutellum. Legs brownish yellow; fore and mid coxae whitish yellow; dorsal surface of hind coxa brown in Taiwanese specimens; teeth of tarsal claws black. Metasoma brownish yellow; 5th–8th tergites and 6th–7th sternites brown to blackish brown (brown). Wings hyaline; stigma yellowish brown; other veins brownish yellow.

♀. Similar to male except: fore, mid and hind tarsal claws with 16 teeth each; 1st– 3rd metasomal segments yellow, 4th tergite onwards and 5th sternites onwards blackish; ovarian egg ( Fig. 10 View FIGURE 10 ) about 0.6 mm long and 0.2–0.3 mm high with stalk on posterior 0.8; posterior 3/4 of ventral half echinulate, the sculpture stronger and denser postero-ventrally.

Length of fore wing: 5.6–7.7 (7.7) mm.

Distribution. Oriental region ( Taiwan, Vietnam, Laos).

Etymology. Named after the infuscate 5th–8th metasomal segments.

Remarks. This is the sixth extant species of the subgenus Parabates , and is considered to belong to the ishiharai group in having the fore wing vein 1cu-a antefurcal to M&RS and the presence of a spine on dorsal margin of paramere of male genitalia. In the species group, N. (P.) fusciapicalis is similar to ishiaharai in having the long spine of paramere but can be distinguished from the latter by rather weakly tapering paramere (width at apex of lamina volsellaris 1.4× as width at base of spine in fusciapicalis and 1.8–2.0 × in ishiharai ) and from the other species of the group by the coloration.

This is the first record of the genus Netelia from Vietnam and Laos, and first record of the subgenus Parabates from Taiwan.
