Figure 2G-I, O Type material. Holotype , female, Ecuador: Napo Prov. [= Orellana Prov.], Tiputini Biodiversity Station, 00°37'55"S , 076°08'39"W , 220-250 m, June 1998, T.L. Erwin et al. collectors, insecticidal fogging, terra firme forest, trans[ect] 4, sta[tion] 5, Erwin lot #1834 (ICB). Diagnosis. 2.4 mm (n = 1), 2.67 x as long as wide. This species is distinguished by the elytral apex attenuate and weakly emarginate, declivital interstriae 2 convex, declivital interstriae 1-3 denticulate, posterolateral margin of declivity with interstriae 3 and 9 joining, forming a carina and continuing submarginally to apex, stout form, declivital interstriae 1 with a uniseriate row of erect scale-like setae, and posterior ~40% of elytra gradually tapered to apex. Similar species. C. barbicauda , C. capillisoror , C. hansen , C. schulzi , C. subtilis , C. trinity , C. uhura . Description (female). Holotype 2.4 mm, 2.67 x as long as wide. Body light brown, elytral declivity darker, antennae and legs lighter. Head : epistoma smooth. Frons dull, finely punctate, setose; each puncture bearing a long, erect hair-like seta. Eyes broadly and moderately emarginate. Submentum narrow, triangular, deeply impressed. Antennal scape short and thick, as long as club. Pedicel shorter than funicle. Club circular, flat, type 3; segment 1 corneous, transverse on anterior face, occupying basal ~1/4; segment 2 broad, transverse, corneous; segments 1 and 2 present on posterior face. Pronotum : 1.1 x as long as wide. In dorsal view long and rounded frontally, type 7, sides parallel in basal 3/4, rounded anteriorly; anterior margin with two serrations. In lateral view tall, type 2, disc flat, summit evident, on basal 1/3. Anterior slope with densely spaced, broad coarse asperities, becoming lower and more strongly transverse towards summit. Disc strongly shiny with dense, minute punctures, some longer hair-like setae at margins. Lateral margins carinate on basal third. Elytra : 1.6 x as long as wide, 1.4 x as long as pronotum. Scutellum minute. Elytra attenuate, parallel-sided in basal 64%, then acutely tapered to apex, apex weakly emarginate. Disc smooth, shiny; strial punctures large, deep, each bearing a recumbent seta the length of a puncture; interstriae flat, minutely, moderately punctate, unarmed, each puncture bearing a long, erect bristle-like seta. Declivity gradually rounded, occupying ~2/5 of elytra, shagreened, shiny, declivital face weakly flattened; striae 1 and 2 feebly impressed, strial punctures larger, deeper than those of disc, each puncture bearing a recumbent seta as long as two punctures; interstriae flat, uniformly denticulate along their entire lengths, denticles spaced by two widths of a denticle, setae semi-erect, scale-like, as long as interstriae 1 width; interstriae 1 with a one row of short setae as described for striae on each side of median erect setae. Posterolateral margin with interstriae 3 and 9 joining, forming a carina and continuing submarginally to apex. 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 six and eight large, socketed denticles, respectively. Etymology. For Catherine (Betty) Smith, beloved grandmother of SMS. Betty was a remarkable woman who embodied the theme of 'kick-ass' women: she was a "Rosie the Riveter" (https://www.loc.gov/rr/program/journey/rosie.html) in her youth and later displayed extraordinary fortitude in her battles with cancer. Noun in genitive. Distribution. Ecuador (Orellana). Biology. The holotype was collected by canopy fogging.
