Male genitalia: Ninth sternum without caudomedian excava- 

 tion; ninth tergum sHghtly tapering to long, slender, apicolateral 

 processes. Basistyle with ventral root foot-shaped, the posterior heel 

 poorly developed, dorsal root slender, as long as ventral root ; dististyle 

 long and slender, nearly straight, with capitate tip. Aedeagus with 

 basal arch short, reaching to about a third of total length of aedeagus, 

 basal arms curved and stout; distal portion slender with rounded tip. 

 Parameres each with very large basal knob, stem bent near base, 

 slender, midportion straight, without ventral lobe; distal portion 

 with slightly expanded fringe of fine spines toward the sharp tip. 



Distribution: Ecuador; Panama.

BocAS DEL ToRO PROVINCE: Almirante.

Mojinga Swamp. 

 Colon Province: Cativd. 

 Dari^n Province: El Real, Garachin^. 



Discussion: We have no doubt of the synonymy oi fairchildi with 

 camposi, since this is such a strikingly marked species. We had not 

 seen Ortiz and Leon's paper describing camposi when we prepared 

 our description. 



This species is apparently related to carpenteri Wirth and Blanton 

 and galindoi Wirth and Blanton, which have very similar male 

 genitalia, although the very striking wing pattern of camposi with 

 pale spots straddling the middles of veins Mi and M2 will readily 

 separate it from those two species.

Culicoides carpenteri Wirth and Blanton, 1953, Journ. Washington Acad. Sci., 

 vol. 43, p. 72 (male, female; Panama; fig. wing, mesonotum, palpus, male 

 genitalia). 



Female: Length of wing 0.99 (0.96-1.02, n=10) mm. 



Head. — Eyes narrowly separated, bare. Antenna with flagellar 

 segments in proportion of 20:14:15:15:15:14:15:15:26:27:33:31:43, 

 antennal ratio 1.22 (1.17-1.30, n = 8); distal sensory tufts present on 

 segments III, xi-xiv. Palpal segments in proportion of 10:20:25:10:10, 

 third segment scarcely swollen, 2.4 (2.2-2.7, n=10) times as long as 

 greatest breadth, with a broad, shallow, sensory pit. Mandible with 

 14 (13-14, n=10) teeth. 



Thorax. — Mesonotum elongate, color yellowish brown, anterior 

 portion except humeri darker brown and a narrow median line and 

 a sublateral pair of broader longitudinal bands of brown extending 

 caudad to about middle of mesonotum, or sometimes to scutellum.
