Diagnosis.

Gryonoides obtusus shares the glabrous medial area of lateral propodeal area and dorsal metapleural area, and the short posterior propodeal projection (shorter than wide) with G. brasiliensis and differs from this species in the smooth T3 and the dorsally closed torular triangle. Males of G. obtusus share the long setae on the antenna (more than 2 times as long as flagellomere width) with G. paraguayensis and differ from this species in the short posterior propodeal projection and the rugulose T3.

Description.

Body length: 2500-3100 µm. Color of head (female): black, interantennal process yellow, mouthparts yellow. Antenna color female: radicle, scape proximally light brown, scape distally, pedicel, A3, A4 proximally, A8, A9, A10, A11, A12 brown, A4 distally, A5, A6, A7 white. Color of mesosoma (female): mesoscutellum black, dorsal metapleural region, dorsal mesopectal region medial region of mesoscutum with brownish spot, rest of mesosoma orange. Color of metasoma (female): dark brown, only anterior 4/5th of T3 orange. Female radicle length: elongate, scape 4-4.5 times as long as radicle. Length of setae on male flagellomeres: more than 2 times as long as flagellomere width. 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. Transverse bare band extending between inner margin of eyes present. Upper face concavity dorsal view: convex. Central keel: present; absent. 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: as long as wide or wider than long. Rugulose sculpture on T3: absent. T3 posterior 4/5th: smooth.
