Gryonoides pulchellus Dodd, 1920: 361 (original description); Masner, 1965: 98 (type information); Johnson, 1992: 513 (cataloged, type information).

Diagnosis.

Gryonoides pulchellus is most similar to G. paraguayensis (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 glabrous T3.

Description.

Gryonoides pulchellus var. pulchellus : Body length: 2400-2700 µm. Color of head (female): black, interantennal process yellow, mouthparts yellow. Antenna color female: scape distally, pedicel, A6, A7, A8, A9, A10, A11, A12 brown, A3, A4, A5 yellowish. Color of mesosoma (female): orange; mesoscutellum, hind femur distally brown, rest of mesosoma ochre. 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. 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 diameters 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: crenulate. Facial striae dorsal end: not reaching midlevel of eye. Vertex sculpture: crenulate. 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: smooth; sculptured. T3 sposterior 4/5th of tergite with one or two very weak sulci medially.

Gryonoides pulchellus var. pulchricornis (Fig. 28 ). Body length: 1900-2300 µm. Color of head (female): black, interantennal process yellow, mouthparts yellow. Antenna color female: yellowish, radicle, scape darker then pedicel and flagellum; radicle, scape proximally, A4 distally, A5, A6, A7, A8, A9, A10, A11, A12 yellowish, scape distally, pedicel, A3, A4 proximally brownish. Color of mesosoma (female): mesoscutellum, hind femur distally brown, rest of mesosoma ochre. Color of metasoma (female): ochre, T2, T3 posteriorly, T4, T5, T6, S2, S4, S5, S6 brownish; ochre, T4, T5, T6, S4, S5, S6 brownish.

Gryonoides pulchellus var. doddi (Fig. 27 ). Body length: 2700-2900 µm. 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): orange except black mesoscutellum, medially brown mesoscutum and medially brown propodeum; 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.

Comments.

Gryonoides pulchellus has three color variations with overlapping geographical distributions (Fig. 26 ). Perhaps the most distinct color form is Gryonoides pulchellus var. pulchellus with seven black apical flagellomeres (var. Gryonoides doddi and var. Gryonoides doddi pulrchricornis has the last 5 flagellomeres black or the apical flagellomeres whitish).
