Fore tarsus one dark brown, 2–5 white. T3 and T4 dark brown. Oviscape yellow and shiny. Epandrium yellow. Head: Palpus broadened basally and gradually tapering to apex. Clypeus short, length less than half of width. Three frontal setae. Frontal vitta slightly prominent, shiny. Epicephalon with golden pruinosity. Vertex flattened and slightly pronounced posteriorly, triangular. Inner vertical seta insertion flat, without tubercle. Paracephalon slightly swollen, swelling rounded. Line of black supracervical setae strong. Thorax: Mesonotum golden pruinose with lines of small pale microsetulae sublaterally. Scutellum upturned, triangular.

Crossvein r-m with dark spot. R4+5 and M1+2 ending separately in wing margin. A1+CuA2 as long as CuA2. Female cervical sclerite smooth, without swelling. Abdomen: Tergites covered by sparse yellowish setulae. Female abdomen: Single spermathecal duct apically broad, ending in a cylindrical spermatheca. Paired spermathecal duct divided into a narrow basal half and a broader distal half. Paired spermathecal duct stems strongly convoluted, apical half slightly broader ( Fig. 31 ). Paired spermathecae cylindrical, strongly curved in the middle. Male abdomen: Ejaculatory apodeme bigger than epandrium and with a broad blade, wider than sperm pump. Hypandrium broad, exceeding epandrium length. Phallapodeme extending to anterior limit of hypandrium. Distiphallus long, longer than epandrium and with a phallic bulb subequal in length and width. Distal distiphallus long and convoluted ( Fig. 32 ). Type material: Holotype ( 1 ♀ , SMTD , only images examined): BOLIVIA . Mapiri, Sarampioni, 700 m , coll. W. Schnuse, 1911 (white label). Since the abdomen is missing, sex determination was based on the original description.
