Alvarenga( FSCA). (Specimen point mounted, gender label affixed to paper point; support card, metathoracic wing mounted on support card; locality label; FSCAacronymic label; Holotypelabel; plastic vial with aedeagus.)   Paratypes.None.   Diagnosis.The more angular pronotal tubercle (compare Figs. 30 and 31), South American distribution, and more slender antennal club (compare Figs. 13 and 14) will conveniently distinguish the members of this species from superficially similar specimens of  S. zorropsisOpitz, new species.   Description. Size: Length 6.1 mm; width 1.8 mm. Form( Fig. 131): 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, funicle compressed, length half of antennomere 8. Thorax: Pronotum ( Fig. 31) 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. Male   Figs. 32–35.  Stegnoclavaspp. 32)Metathoracic wing of  S. fumigata; 33)Mesodermal male reproductive organs of  S. velatis; 34)Mesodermal male reproductive organs of  S. fumigata; 35)Mesodermal male reproductive organs of  S. zorropsis.  mesodermal internal reproductive organs( Fig. 33): 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 Brazilduring October.   Distribution.Known only from the typelocality,  BRAZIL: Mato Grosso( Map 1).   Etymology.The specific epithet  velatisis a Latin name that stems from velo(= cover) and the Latin possessive suffix – isand refers to the dark mask-like macula on the frons and epicranium.
