Diagnosis.

1.6-1.7 mm (mean = 1.65 mm; n = 4), 2.67-2.83 × as long as wide. This species is distinguished by the elytral apex attenuate and weakly emarginate, declivity distinctly sulcate along interstriae 2, declivital interstriae 2 unarmed, interstriae 1 and 3 armed, declivital striae 1 and 2 not parallel on declivital face, nearly converging in sulcate area, and minute size.

Description

(female). 1.6-1.7 mm (mean = 1.65 mm; n = 4), 2.67-2.83 × as long as wide (holotype 1.6 mm, 2.67 × as long as wide). Body light brown, antennae and legs lighter. Head: epistoma smooth. 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 long and slender, shorter than club. Pedicel shorter than funicle. Club circular, flat, type 3; segment 1 corneous, transverse on anterior face, occupying basal ~1/3; segment 2 narrow, 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 3/5, rounded anteriorly; anterior margin with two projecting serrations. In lateral view elongate, disc longer than anterior slope, type 7, summit prominent, on anterior 3/5. 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 carinate on basal third. Elytra: 1.5-1.7 × as long as wide, 1.3 × as long as pronotum. Scutellum minute. Elytra attenuate, parallel-sided in basal 67-70%, then acutely tapered to apex, apex weakly emarginate. Disc smooth shiny; strial punctures moderate, shallow, each bearing a recumbent seta the length of a puncture; interstriae flat, sparsely, minutely punctate, unarmed, each puncture bearing a recumbent seta the length of a puncture. Declivity gradual, smooth, shiny, appearing bisulcate, occupying apical 2/5 of elytra; striae not impressed, striae 1 and 2 nearly converging in sulcate area, strial punctures much larger and shallower than those of disc; interstriae impunctate, interstriae 2 moderately sulcate, unarmed; interstriae 1 and 3 strongly costate with eight small granules, each puncture bearing a short recumbent seta. Posterolateral margin with interstriae 3 and 9 joining, forming a costa and continuing submarginally to apex. Legs: protibiae obliquely triangular, broadest at apical 1/4; 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 and six moderately sized socketed denticles, respectively, their length as large as basal width.

Etymology.

Portrayed by Milla Jovovich, Leeloo is the heroine in the movie 'The Fifth Element’ (1997). Noun in apposition.

Distribution.

Ecuador (Orellana).

Biology.
