Allotype, MALE. Body length 10.9 mm. Fore wing 11.6 mm; maximum wing width 3.6 mm. Coloration. (Fig. 1 B). Integument black with weak blue reflections; front leg brown, ventral face pale brown; palpus brown; antenna black dorsally, pale brown ventrally; mandible black, apex pale brown; integument with whitish line on inner margin of eye, below antennal insertion and above clypeus; small yellowish spot on outer margin of eye; wing infuscate; veins brown; pubescence black. Integument. Body pubescence abundant, long, semi-appressed on entire body and wing (Fig. 1 B). Erect setae long, abundant, present on entire body. Punctation small, conspicuous.
Description and measurements as defined for female, except: Head. (Fig. 1 D) Head wide; inner sides of eyes divergent posteriorly, convergent anteriorly. Anterior ocelli large; POL 0.7 × OOL. Mandible slender, long, length 7.8 × width at median portion of mandible, with two apical teeth. Clypeus convex medially; apical margin polished almost inconspicuous. Labrum exposed, total length 0.6 × clypeus length. Antenna elongate, stout; length of fourth segment 2.3 × its width; ratio of first four antennal segments 14:7:19:21; WA3 0.4 × LA3; LA3 0.5 × UID. Mesosoma. Pronotum short (Fig. 1 B), width 4.2 × length on dorsal view, posterior margin slightly angulated medially; mesonotum with one superior-distal fovea; fovea striated. Metapostnotum weakly striated. Fore wing long (Fig. 1 B); maximum width 0.3 × its length; 2Cu cell rectangular in shape, tCu1 vein curved, length 2.0 × its width; 3Cu cell 1.6 × longer than 2Cu. Front, mid, hind tibia spines absent; tibial brush complete, width almost constant. Front tarsal claws bifid; mid, fore tarsal claw dentate. Metasoma. (Fig. 1 B). Metasoma covered by long, semi-appressed setae; T1 constricted distally, T2 wider, resembling node. Terga with long, thick setae; hypopygium with two lateral tubercles on posterior margin.
Genitalia (Fig. 3A–C). Parapenial lobe split; lobe digit-shaped, apex wider than base, base slightly constraint (Fig. 3A, B); parapenial lobe 0.8 × as long as paramere. Digitus wide, bilobed, length 0.8 × paramere length; ventral lobe with apex rounded, convex, dorsal margin of apex with rounded-short extension, rounded extension medially, slightly above half digitus length; dorsal lobe short, reaching base of paramere, bent laterally, dorsal margin with long erect setae. Aedeagus long, as long as digitus, spatula-shaped, apex bilobed; lobes rounded, touching each other (Fig. 3A).

HONDURAS: Cortés, Parque Nacional Cusuco, 5 Km N Buenos Aires, 15°29’N 88°13’W, Malaise trap in oak/pine cloud forest, R. Cave leg., 1♀ 1♂ 15.VII.1995 (MZLU), 1♀ 1♂ 30.VI.1995 (EMUS).
Distribution. Honduras.
Etymology. The specific epithet is derived from the Latin seta meaning “bristle” and rotundus meaning “rounded”. It refers to the setae rounded dilated on the apex of the genital plate present in males. This characteristic is unique to this species.
Variation. No significant variation was observed in the examined specimens.
Host. Unknown.
Remarks. Calopompilus setaerotundus sp. nov. belongs in the C. pyrrhomelas species-group, because it has a fore wing with a long anal lobe, the hind tibia bears distinct teeth, and the body has dense pubescence. Following Townes’ key (1957, pages 13-14) this species keys to C. feroculis (Banks), a species found in the Southeastern USA. The female of C. setaerotundus differs from that of C. feroculis by having the antenna yellow (black in C.
feroculis). Moreover, the propodeum is smooth in C. feroculis (striate in C. setaerotundus). The male of C. setaerotundus differs from that of C. feroculis in that the male of C. feroculis lacks a whitish spot on the outer margin of the eye; also, it has the clypeus rugose, the vertex less convex or without the prominent/ elevated ocelli, and the fore tibia fully black. The male of C. setaerotundus has a whitish spot on the outer margin of the eye, the clypeus is polished, although it is covered by long pubescence, the vertex is extended and convex, and the venter face of the hind leg is pale brown.
