Yau and Marshall
sp. n.
(Figs. 4.1–4.14)
Description:
Body length
1.4–1.8 mm
(males),
1.8–2.1 mm
(females). Generally similar to
B. abundantia
, except the colour contrast between the yellowish gena and the dark brown thorax is more pronounced.
Wing: Distance between radial fork and r-m 4.5x length of r-m; dm-cu 1.5x length of r-m and distance between crossveins 2.5x length of dm-cu.
Male abdomen and terminalia: S5 with a pair of posteromedial lobes, lobes posteroventrally with medially directed spicules; a row of strong setae; row longer than width of modified posteromedial part of sclerite. Cercus flat, wide, flipper-like. Distiphallus LFS sheet-like, apically long and rippled; FDS forming a posteriorly bent tongue; SDS weakly sclerotized, spatulate.
Female abdomen and terminalia: Each spermatheca with 1 hemispherical pit and 1 nozzle-like pit, both pits with scattered dimples.

Etymology:
This name refers to the flipper-like cerci (Latin ‘pinna’: fin, wing).
Comments:
B. pinna
is found at relatively high elevations in the Ecuadorian province of
Napo
, in Baeza and nearby areas of cloud forest on the eastern slopes of the Andes. This species is relatively large when compared to other
Bromeloecia
species, but not as large as
B. magna
. The male cercus of
B. pinna
is usually found extended laterally to different degrees, and is rarely flexed inwards.
