no. 3626 CULICOIDES — WIRTH AND LEE 17 



mm and 0.061 x 0.050 mm, slightly ovoid, with long, slender, sclerot- 

 ized necks. 



Male. — Unknown. 



Types. — Holotype female: Finca Carpenteria, El Tambo, Cauca, 

 Colombia, 2500 m, July 8, 1964, V. H. Lee, tent trap, USNM type no. 

 69401. Paratypes, 6 females: 4, same data as type; 2, same data 

 except July 9, 1964, in light trap. 



Remarks. — This species and the next (for their separation see the 

 discussion of C. andinus) are closely related to each other, but are not 

 closely related to any other known Neotropical species, probably 

 coming closest to the Limai Group. The wing pattern of large pale 

 spots centered in the cells forming 4 or more less complete transverse 

 pale bands across the wing is similar to that of the North American 

 C. crepuscularw Malloch and other species of the subgenus Beltranmyia 

 Vargas, which, however, have only 1 spermatheca and differ in many 

 other characters.

Female. — Length of wing 1.35 mm. 



Head: Eyes bare; nearly contiguous, with a wedge-shaped inter- 

 ocular space bearing a seta-less tubercle above. Antenna with lengths 

 of flagellar segments in proportion of 19—16—17—17—17—16—16—16—18— 

 19-22-22-29, antennal ratio 0.82; distal sensory tufts present on seg- 

 ments in, xin-xv; segments m-x bicolored but the narrow, dark 

 apices not as prominent as in C. monticola. Palpal segments with 

 lengths in proportion of 7-22-23-7-9; third segment short and only 

 moderately swollen, 2.3 times as long as greatest breadth, with a small, 

 round, shallow sensory pit. Proboscis short, P/H ratio 0.60; mandible 

 with 11-12 teeth. 



Thorax: Dark brown; scutum without prominent pattern. Legs 

 brownish, knee spots blackish; femora with narrow, subapical pale 

 rings, faint on hind leg; tibiae with narrow, sub-basal pale rings, hind 

 tibia dark distally; hind tibial comb with 4 spines, the 2 nearest the 

 spur longer, subequal in length. 



Wing: Pattern nearly as in C. monticola; the 2 middle sets of pale 

 spots not coalesced in complete bands; second radial cell dark to tip; 

 pale area over base of wing extending to one-half the distance between 

 basal arculus and r-m crossvein; pale spot over r-m crossvein large 

 and quadrate, extending only slightly into cell M2; poststigmatic 

 pale spot in cell R5 quadrate, not meeting vein Ml; distal pale spot 

 in cell R5 large, broadly meeting anterior wing margin, leaving apical 

 corner of cell dark; cell Ml with 2 elongate, oval pale spots, the
