Andraegoidus translucidus sp. nov.

( Figs 1–2 )

Description. Male. Integument brownish orange. Apices of the mandibles black; antennae brownish orange with the apices dark brown. Prothorax brown; transverse carina of the pronotum with lateral elevations black. Elytra brownish yellow, semi-transparent. Abdomen dark brown.

Head with dense fine, shallow punctures. Antennal tubercles slightly elevated and rounded, with dense fine punctures; two longitudinal carinae between the antennal tubercles. Frons short, transverse and depressed, deeper at sides. Upper eye lobes well separated, the distance between each other equal to the width of the frons; lower ocular lobe subtriangular; sides of head, near outer margin of the lower ocular lobes, elevated. Genae projected, shorter than mandibles, with fine sparse punctures, and with short whitish hairs on ventral region. Mandibles coarsely rugoso-punctate, with short and long white hairs near base, apex smooth and glabrous. Submentum rugose, with long erect white hairs. Antennae filiform, 11 segmented, flattened dorso-ventrally, exceeding elytral apices at segment X; outer margin of segments IV–X and apical ¼ of segment III with longitudinal carina. Scape cylindrical and slightly expanded apically, with dense fine punctures basally and extending sparsely to the apex, and with short whitish hairs. Segment III with sparse shallow punctures, segments III–XI with dense short pubescence; segment III ¼ longer than scape; segment IV–VII subequal in length; segment IV 1 /5 longer than VIII; segments VIII–X subequal in length; segment XI about 2/3 as long as segment III, partly divided and appendiculate.

Prothorax 1/5 wider than long, strongly swollen, rounded at sides, with dense, deep and confluent sexual punctuation; sides of prothorax with two tubercles, one antemedian and the other postmedian; both feebly prominent, postmedian tubercle more visible than the antemedian. Disc of pronotum with short transverse carina, and median elevation slight, at each side of the carina with an oblique elevation directed anteriorly, and with two slight elevations posterior to the carina. Sexual punctuation absent on transverse carina, median and postmedian elevations, anterior and posterior depressions, postmedian tubercle, anterior and posterior borders, and fine median longitudinal band through the pronotum. Prosternum with transverse sulcus; sulcus with short sparse, whitish hairs; anterior margin of prosternum sulcus with a tubercle directed posteriorly, region without punctures. Prosternum with intercoxal process subparallel, smooth, elevated, at most 2/3 as broad as the procoxal cavity; and posterior region curved, slightly projected, and distinctly excavated below. Mesosternum depressed, with long whitish hairs. Mesosternal process with anterior rounded projection, posterior margin sinuous. Mesepimeron with outer margin elevated. Metepisternum excavated anteriorly; in the apical region narrowed, and with a poorly developed glandular pore and without differentiated area. Mesepisternum, mesepimerum, and metepisternum with distinct, decumbent whitish pubescence. Metasternum with long suberect white hairs, denser in the lateral regions.

Scutellum lanceolate, smooth and glabrous, approximately 1/6 length of elytra. Elytra subparallel, 3 times as long as prothorax, convex transversely. Humeri rounded, slightly projected anteriorly, and with open depressions in anterior region; apices slightly sinuous and unarmed.

Femora flattened laterally, with short sparse whitish hairs. Tibiae subcylindrical, gradually expanded to the apex; tibial spurs straight, divergent, and subequal in length.

Sternites smooth, with long and short, white sparse hairs, shorter and denser in the lateral regions. Sternite I twice as long as II, sternites II–IV subequal, sternite V equal to 1/3 of sternite I. Urosternite V with apex truncate.

Measurement (mm). Total length, 14.9; prothorax length, 3.6; greatest prothorax width, 4.4; elytral length, 9.8; humeral width, 4.6.

Type material. Holotype, BOLIVIA, Santa Cruz: Andrés Ibáñez (La Bola), male, 16.XII.1993, Phil Ward leg. ( MNKM).

Etymology. Latin, translucidus means translucent, refers to elytra.

Remarks. Andraegoidus translucidus sp. nov. differs from the other species of Andraegoidus by the following characters: antennae exceeding elytral apices at segment X; prothorax with dense, deep and confluent sexual punctuation (present in males and absent in females); pronotum with short transverse carina, median elevation slight, and two slight elevations posterior to the carina; elytra brownish yellow, semi-transparent.

Although the new species is only known by one male specimen, the uniformity found in the punctuation of the prothorax in the species of Andraegoidus and in others genera of Trachyderini (for example: Aegoidus Buquet, 1838 ; Chydarteres Hüdepohl, 1985 ; Drychateres Hüdepohl, 1985 ; Poecilopeplus Dejean, 1835 ; Seabraellus Hüdepohl, 1985 ), let us to treat this punctuation like sexual punctuation.
