Description

(female). 3.3-3.6 mm (mean = 3.45 mm; n = 2), 2.54-2.57 × as long as wide (holotype 3.6 mm, 2.57 × as long as wide). Body, antennae and legs light brown, elytral declivity dark brown. Head: epistoma tuberculate. Frons strongly shiny, finely punctate, setose; each puncture bearing a long, erect hair-like seta. Eyes broadly and moderately emarginate. Submentum large, triangular, deeply impressed. Antennal scape regularly thick, as long as club. Pedicel shorter than funicle. Club circular, flat, type 3; segment 1 corneous, subconvex on anterior face, occupying basal ~1/4; segment 2 broad, subconvex, corneous; segments 1 and 2 present on posterior face. Pronotum: 1.0 × as long as wide. In dorsal view basic and parallel-sided, type 2, sides parallel in basal 2/3, rounded anteriorly; anterior margin with eight projecting serrations, median pair largest. In lateral view elongate, disc longer than anterior slope, type 7, summit prominent, on anterior 2/3. Anterior slope with densely spaced, broad coarse asperities, becoming lower and more strongly transverse towards summit. Disc reticulate, dull with sparse, minute punctures, some longer hair-like setae at margins. Lateral margins obliquely costate. Elytra: 1.5 × as long as wide, 1.5 × as long as pronotum. Scutellum small. Elytra attenuate, parallel-sided in basal 80-81%, then acutely rounded to apex, apex entire. Disc shagreened, shiny; striae minutely punctate, glabrous; interstriae flat, minutely, sparsely punctate, unarmed, each puncture bearing a short recumbent hair-like seta. Declivity gradually rounded, occupying ~2/5 of elytra, shagreened, dull, declivital face convex; striae deeply impressed, strial punctures as large and deeper than those of disc, glabrous; interstriae raised into vermiculate ridges as high as 4 × strial width, each bearing short fine recumbent seta. Posterolateral margin apically produced, acutely carinate. Legs: protibiae obliquely triangular, broadest at apical 1/4; apical 1/2 of outer margin with eight large, socketed denticles, their length longer than basal width. Meso- and metatibiae flattened; outer margin evenly rounded with ten and nine large, socketed denticles, respectively.

Etymology.

Portrayed by Katee Sackhoff, Kara ‘Starbuck’ Thrace is a heroine in the 'Battlestar Galactica’ television series (2003-2009). The vermiculate elytral declivity gives the species a tough persona like the character it recognizes. Noun in apposition.
