BITING MIDGES — WIRTH AND BLANTON 349 



notch. Basistyle with ventral and dorsal roots subequal, slender, 

 simple; dististyle slender, sinuate with distinctly hooked apex. 

 Aedeagus with rounded basal arch extending to about half of total 

 length of aedeagus, the basal arms distinctly curved; distal portion 

 simple, slender, tapered to rounded apex. Paramere with large 

 basal knob, base of stem slender, abruptly bent, then swollen on sin- 

 uate midportion, no ventral lobe, apex slender and bent ventromesad 

 with a few subapical, very fine hairs. 



Distribution: Mexico; Panama.

Discussion: This species has no close Panama relatives, but belongs 

 to a distinct Central American group along with the Mexican species 

 dampji Root and Hoffman, both species having a similar wing pattern 

 with r-m crossvein darkened and pale spots straddling both veins Mi 

 and M2, and similar male genitalia. C. dampji has much more exten- 

 sive wing spots than scopus and the stems of the male parameres are 

 straight. 



The limai group 



This group consists of small species with wing pattern of large pale 

 spots filling the cells, pale spots present straddling veins Mi and M2 

 in some species; female antenna with sensoria present on segments iii, 

 vii-x (present on xi-xiv only in the doubtful species carpenteri) ; 

 four tibial spines; two spermathecae; male genitalia with ventral root 

 of the basistyle foot-shaped; paramere with simple basal knob, apex 

 fringed, stem straight, ventral lobe present or absent; aedeagus Y- 

 shaped with simple tip; ninth tergum with narrow apex and short 

 apicolateral processes. 



Panama species: Four, possibly sLx: camposi Ortiz and Leon, 

 galindoi Wirth and Blanton, limai Barretto, and tenuilobus, new 

 species. Two species, carpenteri Wirth and Blanton and magnipalpis 

 Wirth and Blanton, are provisionally referred here but their group 

 position is uncertain.
