( Plate 88B–D )

Hybristodryinus resinicolus Engel 2005: 488 .

Description of female (from Engel 2005). Fully winged; length 2.2 mm. Head, mesosoma and metasoma black; antenna, tegula and legs dark brown; wing veins dark brown; wing membrane hyaline. Antenna with flagellomeres longer than wide; basal flagellomeres about 1.25 times longer than wide; more distal flagellomeres progressively becoming longer until about 1.75–2.00 times longer than wide. Integument generally imbricate, without distinct punctures, except few minute punctures widely scattered. Head not visible in frontal view (only visible in dorsaloblique and lateral views), about as wide as mesosoma; occipital carina complete; lateral ocelli located close to occipital carina. Gena about as broad as compound eyes. Pronotum not elongate, with collar distinct and disc slightly enlarged. Notauli complete, formed of deeply impressed foveae converging posteriorly and meeting at posterior margin of scutum. Propodeum reticulate rugose. Apicolateral corners of propodeum strongly projected posteriorly and forming distinct angles. Fore wing with stigmal vein terminating near wing margin ( Plate 88B ); pterostigma long and narrow; metacarpus much shorter than pterostigma; Rs + M vein present strictly as short tubular stub, otherwise evident only as a nearly spectral vein disappearing just beyond transverse tangent at pterostigmal apex. Protrochanter long adn slender. Protarsomere 3 produced into hook ( Plate 88C ). Protarsus chelate. Rudimentary claw present. Enlarged claw ( Plate 88C, D ) shorter than protibia, distinctly longer than arolium, not spatulate, with distal apex curved inward and tapering to point, without peg-like setae or lamellae or teeth along inner margin, without proximal prominence. Segment 5 of protarsus ( Plate 88C, D ) probably not distinctly visible, because ignored in the original description. Tibial spurs 1/1/1.
