Mimasyngenes quiuira Galileo & Martins, 1996

( Fig. 3 )

Redescription: Male. General colour chestnut without metallic reflection, head and pronotum darker, protibia and protarsus usually paler; some examples with pale femora, which may be rufous at base. General pubescence uniform, short, grey and recumbent, longer on urosternites, arranged in rows on elytra. Ratio of longest setae to scape 1:1, but both relatively short. General puncturation dense and small, especially on pronotum, elytra with rows of medium-sized punctures, interstices finely reticulate (40x); underside (40x), including metasternum and urosternites finely and densely punctato-reticulate.

Head below and behind inferior lobes distinctly tumescent; frons with short recumbent pubescence, moderately densely punctured with larger (20x) and very small (40x) punctures; eyes small, convex; superior lobes with 4-5 ommatidia/row, narrow and separated by slightly more than twice their own width. Antenna reaches apex of elytra at apex of antennomere IX; scape (0,6 mm) parallel sided, antennomere III (0,5 mm) one third shorter than IV (0,75 mm) and slightly more than half length of protibia (0,85 mm), V-XI (0,5-0,4) subequal.

Prothorax transverse; front margin wider than hind margin; sides almost straight from lateral tubercle to front margin, deeply excised from tubercle to hind margin; lateral tubercles small but prominent, the spine slightly upcurved and directed backwards, situated just before basal third. Pronotum: surface partially hidden by short, recumbent pubescence; reticulate with small, dense punctures, these rounded or transverse.

Elytra slightly wider behind middle, convex, broad area around scutellum slightly more so; with seven well defined rows of pubescence, the pubescence short, almost squamous; and seven regular rows of punctures, those of innermost rows becoming smaller and evanescent on apical third.

Femora equally enlarged, peduncles short, one third length of femur, metafemora with apical patch; metatibia enlarged, widest before middle, the lateral surface with elliptical patch of brownish, dense pubescence; metatarsus (0,85 mm) slightly shorter than metatibia (1,0 mm), whole of dorsal surface occupied by equivalent of metafemoral patch.

Male urosternite V as long as IV, feebly convex, apex truncate.

Sexual dimorphism: Female: head below inferior lobes strongly tumescent; superior lobes wider, separated by twice their own width; antenna reaches apex of elytra at apex of X; urosternite V slightly longer than III+IV, centre of apical half with transverse depression.

Variation: Bolivian specimens show little variation, but the type material from Itapira , São Paulo have pale chestnut elytra, and other minor differences .

Measurements (mm): 2 males / 3 females respectively: total length 4,2-4,4/3,9-5,2; width of pronotum 1,0-1,1/1,1-1,3; length of pronotum 0,9/0.8-1,0; length of elytra 3,0/2,8-3,8; width at humeri 1,4-1,5/1,4-1,7.

Specimens examined: BOLIVIA, Chuquisaca, 20°36’S / 63°17’W, c. 500 m, 21 km N Machereti , 11.I.2005, R . Clarke / P. Koch col., beaten from semi-dry Acacia branches, 1 male, 1 female ( MZSP); 1 male and 2 females ( RCSZ) .

Discussion: Group 1 species. M. quiuira is readily separated from M. lineatipennis by the prominent spine of the lateral tubercle, and from M. lepidotus by the regular rows of pubescence on the elytra. The presence of M. quiuira in Bolivia represents a considerable range extension for this species.
