Steleops buitrerensis n. sp.

( Figs. 1–17 )

Diagnosis. Female forewing with well defined dark brown pigmented transverse band, from area anterior to pterostigma to end of veins Cu2 and 1A; along posterior margin, an irregular pigmented band from R4+5 to cell Cu1a, leaving clear windows at margin; pterostigma with a dark brown band along posterior end, other brown spots as illustrated ( Fig. 1 ). Male forewing hyaline, pterostigma as in the female ( Fig. 9 ). Head with compound eyes distinctly pedunculate in both sexes, more in the male ( Figs. 3 , 12 ). Both sexes with a distinct head pattern, broader in the male ( Figs. 3 , 12 ). Female subgenital plate with lateral arms anteriorly, pigmented area broadly triangular, pointed in the middle; posterior projection long, stout, with brown pigmented bands on each side ( Fig. 5 ). Male hypandrium broad, with a row of denticles along left margin ( Fig.13 ). Phallosome broadly rhomboid, with a welldefined “wing” on each side, posteriorly ( Fig. 14 ).

Female. Color. Body pale brown, with dark brown areas as indicated below. Compound eyes black, ocellar field dark brown. Head pattern complex, dark brown clypeal striations and well marked two dark brown bands, from each compound eye, the upper one to the ocellar field, and the lower one forming an arch from eye to eye, and with two small side projections, the lower one enclosing the antennal fossae; a clear narrow area between upper and lower bands, the lower band much slender than the upper one ( Fig. 3 ). Maxillary palps pale yellowish, with Mx4 pale brown distally. Antennae pale yellow ( Fig. 4 ). Legs cream yellowish, hind coxae dark brown. Forewing as in diagnosis. Hindwing hyaline. Tergal lobes of meso and metathorax more pigmented than rest of the thorax. Abdomen pale brown, with irregular brown spots dorsally.

Morphology. Antennal flagellomeres with short, sparse setae ( Fig. 4 ). Forewing ( Fig. 1 ) with pterostigma narrow anteriorly, wide posteriorly; Rs-M diverging from a point, R2+3 about twice as long as fork stem; cell Cu1a trapeziform, about as wide as tall. Subgenital plate ( Fig. 5 ) broad, setose, with anterior pigmented area as illustrated, posterior projection long, stout, distally broad, setose in distal third. Ninth sternum broad, semi-membranous, almost straight posteriorly, rounded anteriorly, with the sides straight in posterior half, then curved towards anterior border; spermapore circular, surrounded by a pigmented rim ( Fig. 7 ). Gonapophyses ( Fig. 6 ): v1 long, slender, distally pointed, v2 long, stout, sides almost parallel, distally rounded, v3 oval shaped, with strong marginal setae. Paraprocts ( Fig. 8 ) almost triangular, apically rounded, setose as illustrated, sensory fields with 28–30 trichobothria issuing from basal rosettes. Epiproct basally wide, almost trapeziform, with field of setae mesally and row of setae along posterior border ( Fig. 8 ).

Measurements. FW: 4125, HW: 2881, F: 925, T: 1950, t1: 785, t2: 185, ctt1: 35, Mx4: 252, f1: 940, f2: 960, IO: 594, D: 289, d: 380, IO/d: 1.56.

Male. Color. Same as the female, head pattern with upper bands almost reaching the compound eyes and lower band much broader than in the female. Forewings hyaline, unpigmented, pterostigma as in the female.

Morphology. Antennal flagellomeres with long setae ( Fig. 11 ). Forewing as in the female, with Rs fork slightly longer ( Fig. 9 ). Hypandrium assymetrical ( Fig. 13 ). Phallosome as in diagnosis ( Fig. 14 ). Paraprocts ( Fig. 15 ) elongate, with slender, acuminate distal process; sensory fields with 22–24 trichobothria in basal rosettes. Epiproct broadly pear shaped, projected posteriorly in the middle, apex of projection rounded ( Fig. 15 ).

Measurements. FW: 3412, HW: 2344, F: 787, T: 1637, t1: 710, t2: 160, ctt1: 35, Mx4: 160, f1: 810, f2: 820, IO: 487, D: 243, d: 315, IO/d: 1.55.

Specimens studied. Holotype male, COLOMBIA. Valle del Cauca. Santiago de Cali, La Buitrera (03o 22’ 19.8’’N: 76o 34’ 12.2’’W), 1150 m., xi.2008, on Acacia sp. tree trunks. MUSENUV slide cod. 23267. Paratypes: 12 females (11 MUSENUV cod. 23269, 1 slide MUSENUV cod. 23268), 4 males (MUSENUV cod. 23270). R. González. On Ficus sp., Acacia sp., and Swietenia sp., tree trunks.

Etymology. The specific name, a noun in apposition, refers to the type locality.
