Xu 2012 Furcotanilla Fig 21-24.jpg

Xu (2012) - Holotype: TL 2.7, HL 0.52, HW 0.40, CI 77, SL 0.43, SI 108, PW 0.36, AL 0.80 (Bolton, 1990); ML 0.26, PNL 0.17, PNH 0.29, PNW 0.24, PPNL 0.18, PPNH 0.33, PPNW 0.25.

In full face view, head longer than broad, anterior 1/3 of the head distinctly narrowed forward. Lateral sides weakly convex, anterolateral corners prominent and tooth-like. Occipital margin weakly concave, occipital corners roundly prominent. Mandibles elongate and down-curved apically, dorsolateral surface with a longitudinal groove, basal corners rounded, masticatory margin with about 14 peg-like teeth. Labrum with a pair of peg-like teeth. Clypeus roughly trapezoidal, anterior margin slightly concave. Antennae 12-segmented, scapes surpassed occipital corners by about 1/10 of its length, flagella segments 2-8 about as broad as long.

In profile view, pronotum slightly convex. Promesonotal suture complete but not depressed. Dorsum of mesonotum straight, almost horizontal. Metanotal groove widely shallowly notched. Dorsum of propodeum straight, slightly slope down backward; posterodorsal corner roundly strongly convex; declivity weakly convex, about 1/2 length of the dorsum. Propodeal spiracle small and circular, lower down on side. Metapleural bulla elongate elliptical and horizontal, close to the spiracle. Petiolar node roughly trapezoidal, weakly narrowed upward; anterior face weakly concave, dorsal face strongly convex, posterior face nearly straight; anterodorsal corner roundly protruding, higher than posterodorsal corner, the latter rounded; the shapes of ventral face and subpetiolar process are not clear because concealed by the hind coxa and femur. Postpetiole moderately inclined forward, dorsal face roundly convex, anterior face weakly convex, anterodorsal corner roundly extruding; anteroventral corner roundly protruding, posteroventral face weakly convex. Sting strong and extruding.

In dorsal view, petiolar node roughly rectangular and slightly widened backward, distinctly broader than long, lateral sides weakly convex. Postpetiolar node weakly widened backward, slightly wider than petiolar node, lateral sides weakly convex.

Mandibles, head, and body smooth and shining. Dorsa of head and body with sparse suberect hairs and abundant decumbent pubescence. Scapes with sparse subdecumbent hairs and abundant decumbent pubescence. Tibiae with abundant decumbent pubescence, but without standing hairs. Mouthparts with abundant longer hairs, apex of mandible with a long stout hair. Color brownish yellow. Mandibles, antennae, and legs yellowish.
