Gastrodynerus aimara Grandinete & Cortes , sp. nov.

( Figs 8 , 19, 21 , 28)

Comments and diagnosis. We decided to use a male specimen as the Holotype, because the only female specimen is in bad condition, missing most of the metasoma and wings. Males of Gastrodynerus aimara and G. barretti are similar in color, pubescence and structure patterns, but it can be separated by the sculpture of T1. The former has smaller sparser punctures, homogeneously distributed on T1, while the latter has the basal portion of T1 with strong reticulated punctures.

Description. Holotype male

Color: Clypeus with four wide yellow marks; dorsal portion of pronotum with yellow mark only on central portion. Except for these, all other color patterns match Gastrodynerus barretti .

Pubescence: Same pattern as Gastrodynerus barretti .

Sculpture: Same pattern of punctation as Gastrodynerus barretti , except on T1, where punctures are coarse and deep, but sparser.

Structure: Clypeus as long as wide, convex in lateral view, with two apical teeth; inter-antennal region longitudinally cariniform, with a deep pit right beside the carina, on inferior half, and one adjacent to the antennal socket, on upper half; F11 hooked-shape, pointed, with the apex not surpassing the apex of F9; occipital carina well developed along the gena, becoming weaker on dorsal surface. Lateral pronotal carina present; pronotal carina on dorsal surface absent; pronotal fovea present; humeral region weakly projected; parategula lamelliform, flattened laterally; scutellum flattened; a longitudinal furrow on the dorsal surface of propodeum; longitudinal carina on posterior surface of propodeum uniform all along; submarginal carina fused to the propodeal valve, weakly projected and pointed; external margin of propodeal valve rounded; longitudinal carina on posterior coxa weakly projected, rounded; T1 a little longer than wide, strongly concave on central region (on lateral view); transverse carina on anterior region of S1; T2 longer than wide; S2 strongly truncate at the base; row of small teeth on apex of S6. Male genitalia as in Figure 28 .

Female: Clypeus wider than long, entirely black; yellow marks on head smaller than males.

Etymology. The epithet is in honor of one of the best-known ethnicities of Bolivia, the Aymara , which is also one of the official languages. It is to be treated as a noun in apposition.

Distribution. Bolivia (La Paz).

Type material. The holotype male ( AMNH) is in good condition and bears the labels: ‘ BOLIVIA: Coroico- / Chulomani , La Paz / III-7-1968 / Garcia & Porter’ . One paratype male ( AMNH) is in good condition and bears the label: ‘Coroico/Yungas/Bolivia’ ‘April/99’ ‘[Label with the genitalia and hind right leg attached]’ ‘[not identified information]’ . The paratype female ( AMNH) is missing mid tarsi, T3–T6 and S3–S6, bearing the same label as Holotype . The paratype male ( AMNH) is in good condition and bears the labels: ‘Coroico/Yungas/Bolivia’ ‘ April 99 ’ ‘[undetermined information]’
