Diagnosis.

Gryonoides paraguayensis is the most similar to G. pulchellus (the two species share the glabrous medial area of lateral propodeal area and dorsal metapleural area, and the long posterior propodeal projection (at least 1.5 times as long as wide), and the dorsally closed torular triangle) and differs from this species in the rugulose T3. Males of G. paraguayensis have longer setae on its flagellomeres (more than two times as long as flagellomere width), whereas males of the puchellus group have shorter setae on their flagellomeres (less than 2 times as long as flagellomere width).

Description.

Body length: 2450-3125 µm. Male antenna color: scape and pedicel yellow, flagellum dark brown. Color of head (female): black, interantennal process yellow, mouthparts yellow. Antenna color female: radicle, scape, pedicel, A3, A4, A5, A6, A7 yellowish, A8, A9, A10, A11, A12 brown. Color of mesosoma (female): internotaular area, mesoscutellum, propodeum dorsally of lateral propodeal carina brown, rest of mesosoma orange. 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. Length of setae on male flagellomeres: more than 2 times as long as flagellomere width. Torular triangle and central keel continuity: torular triangle closed dorsally, continuous complete 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 the width of 2-3 ocelli diameter lateral to dorsal region of torular triangle present. 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: punctate. Notaulus: present. Notaulus anterior end: anterior to the transscutal line. Dorsal metapleural area: glabrous. Anteromedial pits of propodeum: present. 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: present. T3 posterior 4/5th: sculptured.

Comments.

Besides the sculpture of T3, G. paraguayensis also differs from G. pulchellus var. pulchellus in the color pattern of the female antenna and metasoma.
