HOLOTYPE: PERÚ: Madre de Dios: Los Amigos Biol. Sta., 12.56922°S 70.1°W, 268 m, 23 Dec 2010, C. Weirauch, 1♂ ( UCR _ ENT 00044348 ) ( UCR). GoogleMaps

DIAGNOSIS (figs. 1, 3, 5, 6): Recognized by the small body size, large eyes, brown, castaneous, and pale yellow coloration with faint veins, and symmetrical pygophore with right and left protuberances of similar size and with similar setation. Similar in coloration to C. americanus and C. confusus , but much smaller and with larger, more globose eyes. Pygophore most similar to those in C. globosus , C. medius , and C. robustus , n. sp., in being symmetrical, but distinguished by size and coloration.

DESCRIPTION: Male: Total length 6.8 mm, ratio total length to corium width ~3.1, macropterous, hemelytron reaching apex of abdomen. COLORATION: Dorsum castaneous, with small pale yellow mark at base of membrane, membrane veins slightly to distinctly lighter, dorsal laterotergites brown with triangular pale yellow marks; head castaneous with anteocular area lighter than posterior, first labial segment light castaneous, with remaining segments reddish pale yellow, antenna castaneous, with scape somewhat lighter than remaining segments, legs pale yellow to light brown, with femora distally and two or three longitudinal stripes dorsally, tibiae, and tarsi slightly darker, pleura castaneous, abdominal mediosternites brown, ventral laterotergites 2–6 with small pale yellow patches. SURFACE AND VESTITURE: As in generic description. STRUCTURE: Head ~1.4× as long as wide, eyes in dorsal view large, strongly semiglobular, ratio head width to synthlipsis ~3.9, globular in lateral view, dorsal eye margin surpassing dorsal head surface. Antenna as in generic description, proximal pseudosegment of pedicel ~2.4× as long as scape. Labium as in generic description. Thorax as in generic description, anterior pronotal lobe ~6.5× longer than posterior lobe, posterior lobe narrow, coarsely punctate; scutellum with acute tip. Wings as in generic description with two clearly delimited cells in membrane. Legs as in generic description with ratio forefemur height to length ~0.35 (0.33–0.37). Abdomen as in generic description. Genitalia with pygophore symmetrical, protuberances laterally rounded and dorsally flattened, right and left of similar size, spinelike setae on right and left of similar size, right and left with less than 10 conical spinelike setae; parameres slender, right slightly larger than left, rounded sickle-shaped with proximal area slightly shorter than distal, proximal area with sparse, slender, and short setae, distal area flattened into blade, broader on right than on left paramere, tapering to apex.

Female: As in generic description, submacropterous, total length 6.6–7.2 mm, ratio total length to corium width ~2.8–3.4, ratio forefemur height to length ~0.36. Genitalia: as in generic description.

ETYMOLOGY: Named for Bruce D. Gill, who has collected and made available to us from his personal collection (BDGC) the single largest assemblage of Camarochilus specimens.

DISTRIBUTION: Known from lowland Amazonian rainforest in Peru, Colombia, and Venezuela. This species was collected at the same locality as C. americanus in Venezuela. The two species are clearly separated by size and other diagnostic features.

DISCUSSION: This is one of the smallest species of Camarochilus and stands out by its large eyes and relatively stout forefemur. Both female paratypes are submacropterous. Additional specimens would need to be examined to test if this is a species diagnostic feature. The holotype was nondestructively DNA-extracted and the sequences were incorporated into a phylogenetic analysis of Heteroptera ( Weirauch et al., 2019).
