Diagnosis.

Gryonoides fuscoclavatus is the most similar to G. flavicava as these species share the lack of dark brown or black apical flagellomeres and a central keel. The antenna of G. flaviclavus is exclusively yellow ( G. fuscoclavatus has a distally gradually darkening clava; yellow proximally to light brown distally); basal grooves on T3 in G. flaviclavus do not extend to the transverse midline of the tergite (in G. fuscoclavatus , sulci arising from basal grooves exceed posteriorly midlevel of tergite) and the vertex posterior to lateral ocelli is with rare pilosity in G. flaviclavus (pilosity of the vertex more dense in G. fuscoclavatus relative to that of G. flaviclavus ).

Description.

Body length: 2300-2400 µm. Color of head (female): black, interantennal process, radicle, scape, pedicel, A3, A4, A5, A6, A7 yellow, A8, A9, A10, A11, A12 brown. Color of mesosoma (female): mesoscutellum, hind femur distally brown, rest of mesosoma ochre. Color of metasoma (female): dark brown, only anterior 4/5th of T3 orange; brown, only anterior 4/5th of T3, T2, T1, and S2, S1 laterally orange; ochre, only tergites posterior to T3 brown. Female radicle length: elongate, scape 4-4.5 times as long as radicle. Torular triangle and central keel continuity: torular triangle opened dorsally, not continuous reduced central keel. Torular triangle: present. Torular triangle dorsal limit versus midlevel of upper face: torular triangle extending to horizontal (transverse) midline of upper face. Transverse setal fields on upper face: absent. Upper face sculpture: granulous dorsally. Two bare patches equals width of 2-3 ocelli diameters lateral to torular triangle present. Upper face concavity dorsal view: convex. Central keel: absent. Head shape anterior view: head triangular in anterior view (longest head width dorsal to horizontal midline of head). Occipital carina structure dorsomedially: crenulate. Facial striae dorsal end: not reaching midlevel of eye. Vertex sculpture: punctate. Notaulus: present. Notaulus anterior end: anterior to the transscutal line. Dorsal metapleural area: glabrous. Anteromedial pits of propodeum: absent. Area between plica and lateral propodeal carina sculpture: carinate (1 or 2 carinae present). Number of longitudinal carinae between plica and longitudinal (dorsal) section of lateral propodeal carina: 1. Medial region of lateral propodeal area pilosity: glabrous. Posterior propodeal projection length: more than two times as long as wide. Rugulose sculpture on T3: absent. T3 posterior 4/5th: sculptured.
