Type material. Holotype, female: “ Peru, Madre de Dios, Los Amigos Biological station, S12º 34'09'' W70º06'0'', ex Cecropia leafstalk, Hulcr & Smith, leg. 26 Apr 2008 ”. The holotype is deposited in MUSM – Lima. Paratype: same data as holotype, deposited in USNM (1).

Diagnosis. Interstriae 10 sharply elevated far beyond level of metacoxae, protibiae without additional mesal tooth. Affiliated with species in the atratus group by the widely separated procoxae and broad protibiae. Distinguished from all species of that group by the closed ring of long erect golden setae in the female frons.

Description female. Length 2.5 mm, 2.15 times longer than wide; colour dark reddish brown. Head. Eyes separated above by 3 times their width. Frons concave from eye to eye and from epistoma to just above upper level of eyes; surface densely punctured. Vestiture consisting of a circle of moderately long protruding setae along concave margin, longest setae slightly longer than scapus, very fine short setae in concave area. Antennal club with two procurved sutures (appears like three sutures at certain angles) marked by long and short setae; a partial septum at suture 1. Funiculus 6-segmented. Submentum area weakly impressed. Pronotum 1.1 times longer than wide, widest at base, broadly rounded in front; tiny asperities on anterior third; surface reticulate, dull, with small, deep punctures to anterior margin spaced on average by 2–3 times their diameter. Vestiture consisting of fine setae along anterolateral margins and 8 long erect setae along margins (4–2–2), some additional longer setae intermixed along the front margin. Elytra 1.4 times longer than wide, 1.5 times longer than pronotum; sides straight, broadly rounded behind; striae not impressed, punctures moderately large, shallow but sharply demarcated, confused, spaced on average by half the diameter of one puncture; interstriae approximately as wide as striae, difficult to define, punctures absent, with small granules at base of erect setae. Interstriae 10 reaching ventrite IV. Vestiture consisting of erect interstrial setae spaced by the length of a seta; microscopic setae present in strial punctures close to elytral margins. Legs. Procoxae separated by the width of a coxa. Mesocoxae separated by 1.2 times the width of one procoxae. Protibiae broad, robust, with a strong protibial mucro bent laterad; distal lateral teeth 1 slightly shorter than 2, 3–4 additional spines or rugae towards base of tibiae, area between tooth 2 and the next two proximal spines extended laterally by thin cuticle, posterior face with long scattered setae. Mesotibiae with 8 lateral socketed teeth on distal two-thirds. Metatibiae with 7 lateral socketed teeth on distal half. Ventral vestiture. Setae on mesanepisternum trifid, on metanepisternum simple.

Male. Not known.

Key. Leads to couplet 7, with no further match.

Etymology. From Latin solarius , meaning ‘relating to the sun’, with reference to the circle-shaped ring of golden setae in the female frons.

Biology and distribution. Only known from the type locality. It was collected from a Cecropia leafstalk.
