Diagnosis.

Gryonoides flaviclavus is the most similar to G. fuscoclavatus 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.

Gryonoides flaviclavus var. flaviclavus . Body length: 2400-2600 µm. Color of mesosoma (female): orange. Color of metasoma (female): dark brown, laterotergites light brown. Torular triangle: present. 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 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 lateral to dorsal region of torular triangle equal width of 2-3 ocelli diameter present. Upper face concavity dorsal view: convex. Central keel: present. Head shape anterior view: head rounded in anterior view (longest head width in horizontal midline of head). Occipital carina structure dorsomedially: not crenulate. Facial striae dorsal end: not reaching midlevel of eye. Vertex sculpture: smooth. 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: 2. 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 sculpture: posterior 4/5th of tergite smooth; posterior 4/5th of tergite sculptured.
