description: Camarochilus medius, n. sp.   Figures 2, 3, 5–7, table 1  
HOLOTYPE: HONDURAS: Choluteca: 14 mi NW Choluteca, 13.45508°N 87.31686°W, 185 m, 17 Jun 1974, O’Briens and Marshall, 1♂ (UCR _ ENT 00046695) (CAS).  
DIAGNOSIS (figs. 1, 3, 5, 6): Recognized by the medium body size, fairly small eyes, fairly uniformly brown and castaneous coloration with faint veins, and symmetrical pygophore with right and left protuberances of similar size and with similar setation, right paramere with capitate apex. This species does not closely resemble any of its congeners.  
 DESCRIPTION: Male: Total length 7.5 mm, ratio total length to corium width ~3.4, macropterous, hemelytron reaching apex of abdomen. COLORATION: Dorsum brown with castaneous corium, claval commissure lighter brown, membrane veins concolorous to slightly lighter, dorsal laterotergites brown with large triangular pale yellow marks; head brown with anteocular area lighter brown, first labial segment light brown, remaining segments pale yellow, antenna light brown, legs with coxae, trochanters, femora proximoventrally light brown, distal margin of femora, and proximal margin of tibiae light brown, remainder of femora, tibiae and tarsi brown, pleura brown to castaneous, abdominal mediosternites brown to castaneous, ventral laterotergites 2–6 with large pale yellow patches. SURFACE AND VESTITURE: As in generic description.   
STRUCTURE: Head ~1.6× as long as wide, eyes in dorsal view moderately large, shallow semiglobular, ratio head width to synthlipsis ~2.7, reniform in lateral view, dorsal eye margin not 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 ~8.4× longer than posterior lobe, posterior lobe extremely 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 ~0.36. 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 moderately stout, right larger than left, angled between proximal and distal area, proximal area longer than distal, proximal area with sparse, slender, and short setae, distal area flattened into blade, only slightly tapering, apex of right paramere capitate, of left acute.  
 Female: As in generic description, macropterous, total length ~ 7.2 mm, ratio total length to corium width ~3.5, ratio forefemur height to length ~0.36. Genitalia: as in generic description.   
 ETYMOLOGY: Named for the intermediate size relative to its congeners, after Latin medius, meaning “middle, moderate.”   
 DISTRIBUTION: Known only from the type locality in Honduras. This species has the northernmost distribution among its congeners, although not among New World Pachynomidae: Aphelonotus simplus Uhler is known from extreme southwest Texas (Schuh et al., 2015).   
 DISCUSSION: This species is unique among Camarochilus spp. in the angular shape of the paramere and the capitate apex of the right paramere. This situation is reminiscent of the distribution of paramere shapes in Aphelonotus, where the tip of the paramere is acute in the majority of the species, whereas it is capitate in Aphelonotus africanus Carayon and Villiers, and Aphelonotus xenos Schuh, Weirauch, and Grillo.
