Paratypes, 6 males, 33 females: 4 males, 31 females, Almirante, 

 October 1952 to March 1953; 1 male, Fort Sherman, Canal Zone, 

 Sept. 28, 1953; 1 male, Mojinga Swamp, Canal Zone, February 1952; 

 2 females, Pina, Col6n Province, Jan. 18, 1954. 



Discussion: This species is most closely related to galindoi Wirth 

 and Blanton and limai Barretto, although vein Mg is straddled by a 

 pale spot, as in the species of the copiosus, daedalus, and iriartei 

 groups. The wing markings are closest to those of antefurcatus , new 

 species, which differs however in having only one pale spot in the 

 anal cell, no pale spot in front of the mediocubital fork, and the hind 

 femora with subapical pale rings. The ventral lobe of the male 

 paramere is more extremely developed, into a rodlike process, in 

 tenuilobus than in any species of Culicoides known to us.

 segments in proportion of 16:10:12:13:11:11:12:13:20:21:22:21:41, 

 antennal ratio 1.18 (1.10-1.27, n=2); distal sensory tufts present on 

 segments in, vii-x. Palpal segments in proportion of 6:13:17:10:8, 

 third segment swollen, 2.1 times as long as greatest breadth, with a 

 broad, shallow, irregular sensory pit. Mandible with 13-14 (n=2)

 nent pattern of yellowish patches, consisting of a submedian pair of 

 large elongate spots, just laterad of which is another pair of very small 

 round spots; hum.eri, a small area around each sensory pit, and entire 

 posterior half of mesonotum yellowish. Scutellum dark brown in 

 middle and yellowish on sides; postscutellum dark brown; pleuron 

 yellow on upper half and dark brown below. Legs dark brown; 

 knee spots blackish; fore and mid femora with very broad subapical 

 bands, all tibiae with very broad basal bands and broad apex of hind 

 tibia, yellowish; hind tibial comb with four (n = 2) spines, the one 

 nearest the spur longest. 



Wing. — Pattern as figured; second radial cell very dark; pale spot 

 over r-m crossvein broadly reaching costal margin; poststigmatic 

 pale spot in cell R5 extended proximad behind second radial cell;
