Type Material. Holotype male [deposited in CMNH] labeled “ Paraguay: / Dept. Central, San / Lorenzo, 18-19 Nov/1986 J.A.Kochalka / uv light trap ”; pinned with holotype label [red paper topmost] and genitalia in glycerin vial . Paratypes [yellow paper] as follows. Capture method is UV

light trap. PARAGUAY: Same collection event as holotype, held in CMNH unless stated otherwise: (30♂ 48♀ CMNH, 2♂ PWMC, 2♂ 2♀ BTRC, 1♂ 1♀ DAHC, 1♂ 1♀ USNM); same as previous except dates 7 XI 1986 (1♂ 1♀), 23–24 XI 1986 (6♂ 14♀ CMNH, 1♂ BTRC), 30 XII 1987 (21♂ 33♀ CMNH, 1♀ PWMC, 1♂ 1♀ TAMU) , 20–24 VIII 1989 (1♂ 1♀), 11 IX 1989 (1♂ 3♀ CMNH, 1♀ PWMC). BOLIVIA: 19 mi NW Villa Tunari , 1 IV 1978 (1♀ MPM) .

Description (Holotype). Adult male. Size: ABL 5.4 mm. Color/Luster: Dorsal color like that of species group. Antennomeres 1–2, mouthparts, legs, and much of venter testaceous. Elytra faintly iridescent. Microsculpture: Pronotum and elytra with stretched mesh strongly impressed. Head: HW/PW = 0.68. Eyes large. Pronotum: PL/PW = 0.65. Sides narrowly rounded, convergent toward

hind angles, subdentate. Base smooth, impunctate. Elytra: Common structural features of the species group. Venter: Prosternal process like that of subgenus. Ventrites with dense, conspicuous pubescence. Ventrite 6 with 2 pairs of long anal setae. Legs: Male protarsi and mesotarsi typical of genus. Metatarsi dorsally with conspicuous setae. Median lobe: Dorsoapical plate short, narrow with ventral hook at tip and a small sharp hook directed into ostium. Endophallus with 2 long rows of densely packed spines that span most of the median lobe, positioned dorsolaterally right and ventrolaterally left. Penile ostium relatively small; spanned in middle by a protruded wedge-shaped lamina pointed proximad, widened apicad, abruptly truncated in dorsal view.

Variation. ABL 4.9–5.5 mm. Females with tarsi unmodified; with 2 pairs of anal setae as in males.

Etymology. The specific name is derived from Greek para (beside) prefixed to ruficollis , in reference to the close resemblance to S. ruficollis .

Diagnosis. Selenophorus pararuficollis is distinguished from the other members of the ruficollis species group in the remarks for S. neoruficollis .

Type Habitat. The holotype was collected in the Central District, which is the smallest and most densely populated of the 17 districts in Paraguay. This area ranges in elevation from 200–500 feet and is within the “Humid Chaco” ecological region characterized by extensive savannahs of palms with wetlands, estuaries, and gallery forests dominated by Lake Ypacarai and several rivers and river tributaries of Rio Paraguay.

Remarks. The single paratype specimen from Bolivia shares the same collection event as that of three typical specimens of S. ruficollis .
