Description

(female). 1.7-2.0 mm (mean = 1.84 mm; n = 5), 2.83-3.17 × as long as wide (holotype 2.0 mm, 3.08 × as long as wide). Body brown, antennae and legs lighter. Head: epistoma tuberculate. Frons dull, finely punctate, setose; each puncture bearing a long, erect hair-like seta. Eyes narrowly and moderately emarginate. Submentum large, triangular, slightly impressed. Antennal scape short and thick, shorter than club. Pedicel shorter than funicle. Club circular, flat, type 3; segment 1 corneous, transverse on anterior face, occupying basal ~1/4; segment 2 narrow, transverse, corneous; segments 1 and 2 present on posterior face. Pronotum: 1.2 × as long as wide. In dorsal view long and rounded frontally, type 7, sides parallel in basal 2/3, rounded anteriorly; anterior margin without serrations. In lateral view elongate, disc longer than anterior slope, type 7, summit prominent, on anterior 5/7. Anterior slope with densely spaced, broad fine asperities, becoming lower and more strongly transverse towards summit. Disc strongly shiny with sparse, minute punctures, some longer hair-like setae at margins. Lateral margins obliquely costate. Elytra: 1.7-1.9 × as long as wide, 1.5 × as long as pronotum. Scutellum minute. Elytra attenuate, parallel-sided in basal 64-70%, then acutely rounded to apex, apex weakly emarginate. Disc smooth, shiny; striae minutely punctate, each puncture bearing a recumbent seta the length of a puncture; interstriae flat, sparsely, minutely punctate, unarmed, each puncture bearing a long, erect bristle-like seta. Declivity gradually rounded, occupying ~2/5 of elytra, smooth, shiny, declivital face convex; striae not impressed, strial punctures larger, deeper than those of disc, each puncture bearing a semi-recumbent seta as long as four punctures, striae 1 parallel to suture; interstriae flat, interstriae 1 and 3 each with seven and five respectively, uniformly spaced large denticles, interstriae 2 with seven denticles, denticles on interstriae 1-3 subequal, interstrial setae moderately dense erect bristle-like, interstriae 1 with an additional row of slightly shorter setae. Posterolateral margin of declivity costate, armed with three large serrations. Legs: protibiae obliquely triangular, broadest at apical 1/3; 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 Gillian Anderson, Dana Scully is the heroine in the ‘X-Files’ television series (1993-2002, 2016) and movie (2008). We believe in the 'Scully Effect’ (https://seejane.org/research-informs-empowers/the-scully-effect-i-want-to-believe-in-stem/) and hope future female scientists, real and fictional, continue to inspire children and young adults to pursue STEM careers. Noun in apposition.

Distribution.

Ecuador (Orellana).

Biology.

Specimens were collected by canopy fogging.
