Diagnosis. Both sexes are recognized by the elongate body, by the elytral interstriae bearing uni- and biseriate golden setae, by the tenth interstriae with a carina encompassing elytra, and by the unique color pattern described below. The male is distinguished by the moderately excavated frons with the excavation never touching the ocular margin and 6-7 setae lateral to the median line.

Description (male). 3.1-3.5 mm long (mean = 3.3 mm; n = 3); 2.1-2.3 times as long as wide. Head, antennae and thorax orange, legs dark red brown, abdomen black, elytra black with an orange patch covering basal third of elytra from the suture to interstria 8.

Epistoma weakly excavated, excavated from epistoma to anterodorsal margin of the eyes, excavation bordering the ocular margin; expanded to greater than quarter length of head; surface shagreened; nine rows of setae lateral to median line; each lateral margin with a sub-acute vertical costa; apical margin armed with a short rounded tubercle; basal margin tumid above scape insertion (Fig. 2b). Frons weakly excavated from epistoma to anterodorsal margin of the eyes, excavation not reaching the ocular margin; surface shagreened; bearing 6-7 rows of erect golden setae lateral to the median line, surface moderately

Apical pronotal margin broadly rounded (Fig. 5a), area between eyes glabrous; surface minutely granulate-punctate with minute, shallow punctures bearing fine, golden, hair-like setae; anterior fifth bearing 2-3 rows of golden setae; a row of yellow setae above lateral carinae; base weakly recurved (Fig. 8b); carina on lateral margin type C (Fig. 7c).

Scutellum shape type B ( Fig. 12b ).

Elytral sides parallel, narrowing to a smooth apex; base never tumid from interstriae 7-9. Disk with shallow rugosities extending from striae 1 to interstriae 4 and from the base to just beyond the scutellum, remaining elytral surface minutely granulate. Discal striae with punctures 1.5-2 times as large as those of interstriae, shallow, each bearing a fine, golden seta; interstriae bearing mostly uniseriate (occasionally biseriate) golden scales. Declivital interstriae bearing uniseriate rows of golden scales. Tenth interstriae with a carina encompassing elytra. Metepisternum shape type C ( Fig. 9c ); setae palmately divided into 4 or more filaments. Mesosternum shape type E ( Fig. 10e ). Second sternite convex; sternites 2-4 each margined with a row of golden scales, sternite 5 with 2 rows.

Male genitalia. Median lobe flat, proximally wider than distal end, lateral and apical margins with more sclerotization, apex broad, apical orifice lightly sclerotized; lateral margins folded dorsally. Median struts a third of body length. Internal sac central area lightly sclerotized, seminal trough proximal end “Y” shaped ( Fig. 60). Tegmen semi-circular, ventral side elongated proximally. Spicule nearly longer then aedeagus, sickle-shaped with large hook near the distal end.

Female. Similar to male except epistoma less impressed, less than a quarter length of head. Frons flat. Each gena with a circular mycangium (Fig. 4c). Segments 1-7 of funicle bearing scattered setae less than the length of 3 segments. Second sternite convex.

Distribution. Brazil (Amazonas).

Hosts. Unknown.

Biology. Unknown.

Etymology. Igniculus (L) = little flame, spark. Named for its “fiery” appearance (golden setae and reddish-brown color) and in honor of a traditional Cognato family name “Ignatius”.
