HOLOTYPE: COLOMBIA: Stowaway on airplane, intercepted in Miami, 15 May 1938, J. Bache-Wiic, 1♂ ( UCR _ ENT 00026326 ) ( USNM).

DIAGNOSIS (figs. 1, 3, 5, 6): Recognized by the medium body size, medium-sized eyes, blackish brown coloration with concolorous veins, and strongly asymmetrical pygophore with rounded right protuberance much larger and with much larger spinelike setae. Most similar to C. americanus in shape and armature of pygophore, but distinguished by the distinctive blackish brown coloration.

DESCRIPTION: Male: Total length 7.9 mm, ratio total length to corium width ~3.3, macropterous, hemelytron surpassing apex of abdomen. COLORATION: Dorsum blackish brown, membrane veins concolorous, dorsal laterotergites brown with triangular pale yellow marks; head and first labial segment blackish brown, remaining segments pale yellow, antenna light brown, legs with coxae, trochanters, and base of femora pale yellow to light brown, remainder of femora blackish brown, tibiae and tarsi brown, pleura brown, abdominal mediosternites brown, ventral laterotergites 2–6 with large pale yellow patches. 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 ~3.6, reniform in lateral view, dorsal eye margin barely reaching dorsal head surface. Antenna as in generic description, proximal pseudosegment of pedicel ~2× as long as scape. Labium as in generic description. Thorax as in generic description, anterior pronotal lobe ~5.4× longer than posterior lobe, posterior lobe narrow, finely punctate; 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 ~0.37. Abdomen as in generic description. Genitalia with pygophore asymmetrical, protuberances laterally rounded and dorsally flattened, right larger than left, spinelike setae on right much stouter than on left, right and left with ~30 conical, spinelike setae; parameres stout, right larger than left, sickle shaped with proximal area shorter than distal, proximal area with dense, stout, and short setae, distal area flattened into blade, tapering to apex.

Female: Unknown.

ETYMOLOGY: Named for the late Halbert M. Harris ( Slater et al., 2002), who described the two initial species of Camarochilus .

DISTRIBUTION: The distribution of this species is unknown; the two examined specimens were intercepted on an airplane from Colombia.

DISCUSSION: Based on the degree of asymmetry and ornamentation of the pygophore protuberances, we suspect that this species may be closely related to C. americanus and C. picturatus . Both species also occur in Colombia, but C. harrisi , is clearly separated from all remaining species by the very dark coloration of the dorsum.

PARATYPE: COLOMBIA: Stowaway on airplane, intercepted in Miami, 15 May 1938, J. Bache-Wiic, 1♂ ( UCR _ ENT 00027097 ) ( USNM) .
