Diagnosis

Malar space of female of Stenothremma flavator Gupta & van Achterberg sp. nov. is slightly longer than basal width of mandible ( Fig. 12A View Fig ), spiracles of first tergite situated at posterior 0.3–0.4 of tergite ( Fig. 13B View Fig ), head, pterostigma, mesosoma and metasoma dorsally yellowish brown; vein 1-R1 of fore wing 0.6× as long as pterostigma ( Fig. 13A View Fig ); posterior half of first tergite partly finely reticulate; posterior face of propodeum oblique in lateral view ( Fig. 13A View Fig ), ovipositor sheath about half as long as metasoma without first tergite and first tergite apically narrower than at level of spiracles.

Etymology

Named after the yellowish body colour (‘ flavus ’ is Latin for ‘yellow’).

Description

Female (holotype ( NIM / NBAIR / Hym / Brac / Sten / 181220-H ) , Fig. 11 View Fig )

COLOUR. Largely yellowish brown except for black eyes, brown tip of mandibles, brownish 11–12 apical antennomeres and dark brown ovipositor sheath.

MEASUREMENTS. Body length 4.7 mm; ovipositor length 0.9 mm; fore wing length 3.0 mm.

HEAD. Antenna with 20 antennomeres, third antennomere 1.1–1.2 × as long as fourth antennomere, and 4× as long as wide; face densely and evenly setose, finely reticulate; vertex shallowly rugose; in dorsal view temples hardly curved and directly narrowed behind eyes, eye 1.5× as long as temple ( Fig. 12B View Fig ), occipital carina visible in dorsal view; POL:OOL:OD = 15:29:8. Eye 0.7× as long as minimum distance between eyes in anterior aspect; malar space 1.1 × as long as basal width of mandible ( Fig. 12A View Fig ).

MESOSOMA. Pronotum partially smooth medially (dorsal aspect), laterally with prominent longitudinal striae; middle lobe of mesoscutum finely punctulate, notauli crenulate, lateral lobes of mesoscutum almost smooth, setae present throughout except on middle lobe, scutellar sulcus with eight crenulae; propleuron irregularly rugose; mesopleuron finely reticulate with few setae at its apical 0.3; postpectal carina present; propodeum coarsely irregularly areolate-rugose and punctate except for finely punctate medio-longitudinal depression in posterior half. Hind femur 4.9× as long as wide; coxa dorsally rugose ( Fig. 13B View Fig ).

WINGS. Fore wing: m-cu weakly postfurcal (= distad to 2-SR); 1-R1 0.6 × length of pterostigma. Hind wing cu-a:1-M:1r-m = 15:19:13. METASOMA. Tergites smooth, but T1 partly finely reticulate in posterior half, irregularly rugose in anterior half ( Fig. 13B View Fig ). T1 0.8× as long as mesosoma; T1 about 6.3× as long as its apical width; apical width of T1 1.9× its narrowest subbasal width; T1 apically narrower than at level of spiracles ( Fig. 13D View Fig ); ventrally basal half of T1 closed, laterally angulate and spiracles situated at apical 0.3× of T1; ovipositor sheath about 0.7 × as long as T1.

VARIATION. Third antennomere 1.1–1.2 × as long as fourth antennomere; ovipositor sheath about 0.6– 0.7× as long as T1.

Male (paratytpe ( NIM / NBAIR / Hym / Brac / Sten / 100823-P2 ) Fig. 14 View Fig )

Body yellow. Antenna with 19 antennomeres. Remaining characters similar to female except for ovipositor.

Distribution

Known from southern India (Karnataka).

Comments

The new species differs from the similar Stenothremma vieti Belokobylskij, 1993 by having yellowish brown basal half of flagellum (vs dark brown in S. vieti ); eye length 3.9× malar space (in lateral view) (vs 2.8× in S. vieti ); POL 2× OD (vs 1.6× in S. vieti ); first tergite unicolourous (vs anterior one fifth dark brown in S. vieti ); length of first tergite 5.2× its maximum width (vs 5.6× in S. vieti ).
