Diagnosis.

Gryonoides brasiliensis shares the yellowish-orange coloration of the mesosoma and metasoma, the five dark apical clavomeres, the rugulose sculpture on T3 and a complete central keel and dorsally closed torular triangle with G. paraguayensis . The two species differ in the presence of carinae on the vertex in Gryonoides brasiliensis and the length of the posterior propodeal projection, which is as long as wide in G. brasiliensis whereas more than 1.5 times as long as wide in G. paraguayensis . Gryonoides brasiliensis shares the short posterior propodeal projection (as long as wide or shorter than wide) with G. obtusus and differs from this species in the rugulose T3 and the dorsally opened torular triangle.

Description.

Body length: 2300-2400 µm. Color of head (female): black, interantennal process brown, mouthparts yellow. Antenna color female: radicle, scape, pedicel, A3, A4, A5, A6, A7 yellowish, A8, A9, A10, A11, A12 brown. Color of metasoma (female): T1, T2 light brown medially, T3 ochre, T4-T6 medial 3/4th brown, laterally ochre. Female radicle length: elongate, scape 4-4.5 times as long as radicle. Torular triangle and central keel continuity: torular triangle closed dorsally, continuous complete central keel. Torular triangle dorsal limit versus midlevel of upper face: torular triangle extending to horizontal (transverse) midline of upper face. Two bare patches equal width of 2-3 ocelli diameters present. Transverse setal fields on upper face: absent. Upper face sculpture: granulous dorsally. Upper face concavity dorsal view: convex. Central keel: present. 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: crenulate; 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: 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: present. T3 posterior 4/5th: sculptured.
