Type material.

Holotype, female, Brazil: [ Pará], Santarém, Acc. No. 2966 (CNCI).

2.3 mm (n = 1), 2.88 × as long as wide. This species is distinguished by the elytral apex strongly acuminate, declivital interstriae unarmed along its entire length, antennal club with two sutures on posterior face, elytral discal interstriae punctate, and posterolateral margin of declivity with a very short carina extending from apex to interstriae 2.

Description

(female). Holotype 2.3 mm, 2.88 × as long as wide. Body brown, antennae and legs lighter. Head: epistoma tuberculate. Frons subshiny, 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 as long as funicle. Club circular, flat, type 3; segment 1 corneous, transverse on anterior face, occupying basal ~1/3; segment 2 narrow, transverse, corneous; segments 1 and 2 present on posterior face. Pronotum: 1.3 × as long as wide. In dorsal view long and rounded frontally, type 7, sides parallel in basal 2/3, rounded anteriorly; anterior margin with two projecting serrations. In lateral view elongate, disc longer than anterior slope, type 7, summit prominent, on anterior 2/3. Anterior slope with densely spaced, broad fine 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 carinate on basal third. Elytra: 1.6 × as long as wide, 1.3 × as long as pronotum. Scutellum minute. Elytra attenuate, parallel-sided in basal 62%, then acutely narrowed to acuminate apex. Disc smooth, shiny; strial punctures large, shallow, each bearing a recumbent hair-like seta the length of three punctures; interstriae flat, minutely, densely punctate, unarmed, each puncture bearing a long semi-recumbent seta. Declivity gradually rounded, occupying ~2/5 of elytra, shagreened, dull, declivital face weakly convex; striae not impressed, strial punctures larger, deeper than those of disc, each puncture bearing a recumbent hair-like setae as long as two punctures; interstriae flat, nearly devoid of denticles except interstriae 3 coarsely serrate on acuminate projection, interstriae with a row of short erect hair-like setae. Posterolateral margin with a very short carina extending from apex to interstriae 2. Legs: protibiae distinctly triangular, broadest at apical 1/5; apical 1/2 of outer margin with six large, socketed denticles, their length longer than basal width. Meso- and metatibiae flattened; outer margin evenly rounded with seven large, socketed denticles.

Etymology.

Portrayed by Linda Hamilton, Sarah Connor is a heroine in 'The Terminator’ movie and television franchise (1984-2019). The vermiculate elytral declivity gives the species a rough appearance like the character it recognizes. Noun in apposition.
