description: Bromeloecia robustora Yau and Marshall sp. n.
(Figs. 5.1–5.14)
Description: Body length 1.3–1.4 mm (males), 1.3–1.7 mm (females). Generally similar to B. abundantia in external characters.
Wing: Distance between radial fork and r-m 4x length of r-m; dm-cu 1.7x length of r-m and distance between crossveins 1.9x length of dm-cu.
Male abdomen and terminalia: S5 with a pair of posteromedial lobes, lobes ventrally covered with medially directed spicules, dorsally rounded; a row of strong setae; row longer than width of modified posteromedial part of sclerite. Cercus uniform in width, very well sclerotized especially at edges, glossy to semi-glossy; base of cercus with prominent stub. Distiphallus LFS sheet-like, apically curled and weakly sclerotized; FDS form a posteriorly bent tongue; SDS weakly sclerotized, cup-shaped and extends laterally.
Female abdomen and terminalia: S7 simple with 1 row of setae. Cercus teardrop-shaped, apically pointed, with stout apical hooked seta.

Etymology: This name refers to the well-sclerotized edges of the cercus (Latin ‘robustus’: hard, strong, robust; Latin ‘ora’: extremity, edge, margin, coast).
Comments: B. robustora is widespread across South America and occurs at a wide range of elevations. B. robustora and B. abundantia are similar in body size and external characters (see comments below the description of B. abundantia). The cercus of B. robustora is more likely to be found flexed inwards than extended laterally.
