HOLOTYPE: COLOMBIA: Cundinamarca: Anolaima , 4.7633°N 74.4683°W, 1604 m, 15 Apr 1992, I. Garcia, 1♂ ( UCR _ ENT 00021722) ( MPUJ). GoogleMaps  

DIAGNOSIS (figs. 1, 3, 5, 6): Recognized by the medium body size, medium-sized eyes, brown, castaneous, and pale yellow coloration with posterior pronotal lobe lighter than anterior lobe (figs. 1, 3). Similar to C. picturatus   in the contrasting femur (brown) and tibia (pale yellow), but distinguished by the smaller size, concolorous membrane veins, and light- colored posterior pronotal lobe.

DESCRIPTION: Male: Total length ~7.0 mm, ratio total length to corium width ~2.6. COLORATION: Dorsum brown with posterior pronotal lobe graded from lighter brown to pale yellow, corium castaneous, membrane brown with veins slightly lighter, dorsal laterotergites pale yellow with narrow brown band posteriorly; head and first labial segment brown, remaining segments lighter brown, scape and proximal pseudosegment of pedicel brown, remaining segment pale yellow, legs with coxae and femora brown, femora somewhat lighter distally, trochanters, tibiae, and tarsi light brown, pleura brown with posterior margin of propleuron lighter brown, abdominal mediosternites castaneous, ventral laterotergites 2–6 pale yellow with light brown posterior margins. SURFACE AND VESTITURE: As in generic description. STRUCTURE: Head ~1.3× as long as wide, eyes in dorsal view moderately large, shallow semiglobular, ratio head width to synthlipsis ~3.3, reniform in lateral view, dorsal eye margin barely reaching dorsal head surface. Antenna as in generic description, proximal pseudosegment of pedicel ~2.7× as long as scape. Labium as in generic description. Thorax as in generic description, anterior pronotal lobe ~6.6× longer than posterior lobe, posterior lobe narrow, rugose; scutellum with knob-shaped tip. Wings as in generic description with two clearly delimited cells in membrane. Legs as in generic description with ratio forefemur height to length ~0.33. Abdomen as in generic description. Genitalia: pygophore missing.

Female: Unknown.

ETYMOLOGY: Named for the contrasting coloration of the pronotum, with dark anterior and lighter posterior lobe, after Latin fasciatus   , meaning “with stripe or band.”

DISTRIBUTION: Only known from the type locality in the department of Cundinamarca   in Colombia. Compared with all other congeners, this species was collected at fairly high elevation (~ 1600 m) in the Cordillera Oriental west of Bogotá   .

DISCUSSION: We are confident in establishing this new species based on the male holotype that lacks the pygophore for two reasons: coloration and size of the holotype and the highelevation type locality set this species apart from other here recognized species of Camarochilus   . Colombia has the greatest diversity of Camarochilus species   among all Central and South American countries ( C. americanus   , C. fasciatus   , C. gilli   , C. globosus   , C. harrisi   , and C. tenuis   ). However, C. americanus   has only been collected in the extreme northern region of Colombia (south of the Sierra Nevada de Santa Marta), whereas C. gilli   , C. globosus   , and C. tenuis   are known only from lowland Amazonian rainforest localities. The origin of C. harrisi   in Colombia remains unknown because all known specimens were intercepted at Miami airport from an airplane that originated in Colombia.
