Stegnoclava velatis Opitz , new species

( Figs. 14 View Figs , 29, 31 View Figs , 33 View Figs , 39, 131 View Figs ; Map 1 View Map 1 )

Holotype. ♂. Brazil: Mato Grosso: Sinop, X-75, M. Alvarenga ( FSCA). (Specimen point mounted, gender label affixed to paper point; support card, metathoracic wing mounted on support card; locality label; FSCA acronymic label; Holotype label; plastic vial with aedeagus.)

Paratypes. None.

Diagnosis. The more angular pronotal tubercle (compare Figs. 30 and 31 View Figs ), South American distribution, and more slender antennal club (compare Figs. 13 and 14 View Figs ) will conveniently distinguish the members of this species from superficially similar specimens of S. zorropsis Opitz , new species.

Description. Size: Length 6.1 mm; width 1.8 mm. Form ( Fig. 131 View Figs ): Long rectangular. Integumental color ( Fig. 39): Cranium bicolored, lower frons and epicranium yellow at sides, black on top, upper frons and vertex black, antennae dark brown; pronotum dark brown at lower sides and centrally on disc, yellow in upper sides and along anterior margin; elytra mostly yellow, infuscated in anterior half of epipleural margin, dark brown in distal third, legs dark brown, except yellow in proximal half of femora. Head: HW/ PW 1.0; EW/VW 0.81; antenna as in Fig. 14 View Figs , funicle compressed, length half of antennomere 8. Thorax: Pronotum ( Fig. 31 View Figs ) with obtuse lateral tubercle; PL/PW 0.83; elytra long rectangular, EL/PL 5.0; EL/EW 3.3; anterior margin of protibia with 14 spines. Male genitalia: Aedeagus as in Fig. 29 View Figs . Male

mesodermal internal reproductive organs ( Fig. 33 View Figs ): Two pairs of accessory glands, medial pair shorter than lateral pair.

Variation. One specimen examined.

Natural History. The only known specimen was collected in the central highlands of Brazil during October.

Distribution. Known only from the type locality, BRAZIL: Mato Grosso ( Map 1 View Map 1 ).

Etymology. The specific epithet velatis is a Latin name that stems from velo (= cover) and the Latin possessive suffix – is and refers to the dark mask-like macula on the frons and epicranium.
