Coelioxys agilis Smith, 1879: 105 .

Diagnosis. Females of this species are easily recognizable by the triangular excision of the apical margin of the clypeus and the brownish erect setae that form tufts on the lateral sulci of T6. Within the subgenus, these two characteristics are found only in females of this species. Males of C. agilis can be distinguished from all the other C. (Rhinocoelioxys) by the shape of the apical margin of S4. Besides, the area which in other species forms a hypostomal concavity is flat and completely covered by erect white hairs while in other species of the subgenus the concavity is glabrous at least posteriorly.

Redescription. Female. (LACM). “ TRINIDAD & TOBAGO, Trinidad: Mt. St. Benedict, 10,67ºN 61.40ºW, 26 Nov. 1999 rainforest, coll. R. R. Snelling”. “LACM ENT 317983”.

Measurements. Body length: 7.19 mm; forewing length: 4.89 mm; head width: 2.29 mm. Coloration. Black except as follows: Antenna, labrum, legs, sterna dark brown; tegula dark to light brown; wings subhyaline; veins dark brown to blackish.

Pubescence. Pale, subappressed on: Paraocular area, fringe on apical margin of clypeus posteriorly, gena, mandible basally, labrum, interrupted transverse fascia on anterior margin of mesoscutum, mesosoma, legs, basal fascia of T1, apical fasciae of sterna. Ocular hairs pale, long (about 0.12 mm). Scattered erect, slender, white setae on paraocular area. Upper paraocular area with long, brown hairs distinct from those of adjacent regions, oriented mesad, apices of some hairs from each side almost meeting medially. Slender, erect, yellow setae arising from punctures of mesoscutum. Supraclypeal area, clypeus covered with minute, appressed brownish hairs. Clypeal lobes with fringe of thick, brown hairs. Thick, yellow setae on tarsi. T2–T5 apical fasciae composed of appressed, plumose, whitish hairs. Lateral sulci of T6 with short, erect, brown setae.

Surface sculpture. Ocellar area coarsely punctate; vertex, mesoscutum, mesepisternum moderately densely punctate, interspaces among punctures larger than puncture diameter; mesoscutellum coarsely punctate except longitudinal median ridge smooth, almost impunctate; axilla coarsely, densely punctate; T1 moderately densely punctate, interspaces among punctures shining, larger than puncture diameter; pregradular areas of T2–T5 moderately densely punctate, interspaces shining, smooth; postgradular areas of T2–T5 shining, with sparse punctures forming transverse row with additional small punctures medioposteriorly, T6 densely punctate, punctures very small, well separated, punctures denser apically; S1 punctate; postgradular areas of S2–S4 moderately densely punctate basally, more sparsely towards apex, postgradular area of S5 less densely punctate basally, more densely punctate towards apex.

Structure. Apical margin of clypeus with small, triangular excision medially, forming two flat, slightly upwardly oriented, small lobes with acute apices. Mesoscutellum with posterior margin obtusely angulate, longitudinal median ridge present. Axilla long, acute. T6 subacute apically, with small sulcus laterally. Dorsomedian line of T6 obsolescent except forming sharp ridge apically with depressions lateral to the sharp ridge shallow, obsolescent. Apex of S5 rounded. S6 slender, elongate, lateral margins convergent apically, notches obsolete, tip subacute. Hemitergite 7 much longer than wide, area subtended by the marginal ridge narrow; apodemal region greatly produced anteriorly; lateral process reduced; spiracle close to apical margin of lamina spiracularis; lateral lamella wider than lamina spicularis. Dorsal arm of furcula long. Gonostylus subacute apically.

Male. (LACM). “ Brasil, Para, 2. 1902, Ducke”. “ Coelioxys excisa, 1904 Friese det., Fr.”. “LACM ENT 317985”.

Measurements. Body length: 6.67 mm; forewing length: 4.69 mm; head width: 2.08 mm. Coloration. As in female.

Pubescence. As in female except as follows: Face densely covered with pale hairs, hypostomal concavity covered with erect hairs. Apical pale fasciae of T2–T5 broadly interrupted medially, gradular grooves of T2–T6 covered with whitish hairs.

Integument. As in female except as follows: Punctures of mesoscutum larger; mesepisternum coarsely punctate; postgradular areas of T2 and T3 with inconspicuous, transverse, narrow punctate area on each side with some punctures fused; T6 less densely punctate towards base, densely punctate laterally and on dorsomedian excavation, dorsal ridges impunctate; postgradular area of S5 moderately densely punctate, interspaces among punctures shining, larger than the puncture diameter.

Structure. As in female except as follows: Hypostomal concavity shallow, discrete, shorter than half length of compound eye. Spine-like processes of T5 completely fused to the surface of the tergum. Lateral processes of T6 small, triangular, acute, divergent; dorsal processes short, narrow, rounded apically; ventral processes long, acute. Apical margin of T7 semicircular, not strongly produced. Apical margin of S4 bare medially, simple. Apical rim of S4 inconspicuously emarginate, bare medially. Apical margin of S5 simple, gradulus angulate towards base. Gradulus of S6 indistinct but U-shaped, nearly reaching basal margin, pregradular areas narrow, elongate, weakly sclerotized on inner margins, strongly sclerotized along outer margins, narrowly acute at base, apical half of pregradular area densely setose, less setose on outer margins, postgradular area transparent medially, broad at base, basal membranous lip rounded. S7 obsolescent, represented by two small sclerites. S8 rounded basally. Gonocoxa compressed laterally, with some long setae apically, equal to penis valve in length.

Variation. In some specimens the legs and sterna are red to reddish.
