description: Camarochilus robustus, n. sp.   Figures 2, 3, 5–7, table 1  
HOLOTYPE: ECUADOR: Pastaza: Puyo, 1.48625°S 78.00673°W, 800 m, 01 Feb 1976 – 07 Feb 1976, Spangler, et al., 1♂ (UCR _ ENT 00026325) (USNM).  
DIAGNOSIS (figs. 1, 3, 5, 6): Recognized by the large body size, fairly large eyes, uniform coloration with concolorous veins, and symmetrical pygophore with right and left protuberances of similar size and setation. Larger than all other congeneric species.  
 DESCRIPTION: Male: Total length 9.8 mm, ratio total length to corium width ~3.1–3.3, macropterous, hemelytron reaching apex of abdomen. COLORATION: Dorsum brown with corium brown to castaneous, claval commissure and base of membrane somewhat paler, veins concolorous with membrane, dorsal laterotergites brown with small triangular pale yellow marks; head and first labial segment brown, remaining labial segments lighter brown, antenna light brown, legs brown with forefemur except narrow band basally and in distal 3/4 mid- and hind femora darker brown, pleura brown, abdominal mediosternites brown, ventral laterotergites 2–6 with small pale yellow patches. SURFACE AND VESTITURE: As in generic description. STRUCTURE: Head ~1.6× as long as wide, eyes in dorsal view fairly large, semiglobular, ratio head width to synthlipsis ~3.9–4.0, globular in lateral view, dorsal eye margin surpassing dorsal head surface. Antenna as in generic description, proximal pseudosegment of pedicel ~2.8× as long as scape. Labium as in generic description. Thorax as in generic description, anterior pronotal lobe ~5× longer than posterior lobe, posterior lobe moderately wide, coarsely punctate; scutellum with slender tip. Wings as in generic description with two clearly delimited cells in membrane. Legs as in generic description with ratio forefemur height to length ~0.31. 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 15–20 conical, spinelike setae; parameres moderately stout, right slightly larger than left, sickle-shaped with distal area longer than proximal, proximal area with few, slender, and short setae, distal area flattened into blade, tapering to apex.   
 Female: As in generic description, macropterous, total length 9.8–10.4 mm, ratio total length to corium width ~3.1–3.2, ratio forefemur height to length ~0.28–0.31. Genitalia: as in generic description.   
 ETYMOLOGY: Named for the large size of this species, after Latin robustus, meaning “solid, robust.”   
DISTRIBUTION: The male holotype was collected at mid elevation (800 m) in the eastern foothills of the Andes; the female paratype is from an unknown locality in Bolivia.  
 DISCUSSION: We associate the two known specimens based on the large size and drab coloration, despite the two localities being distant from each other. Only the examination of additional specimens will allow for further testing of this species hypothesis. This species is closest in total length to C. confusus, but males are differentiated by the shape of the pygophore protuberances (almost symmetrical in C. robustus, n. sp., right protuberance conical in C. confusus).   
PARATYPES: BOLIVIA: unknown locality (not mapped), 29 Mar 1946, Zischka, 1♀ (UCR _ ENT 00026331) (USNM).
