CICADELLINAE : PART I. PROCONIINI 65 



carina laterad of each ocellus, disc widi sparse pubescence; antennal 

 ledges with or widiout a longitudinal fovea, in lateral aspect with 

 anterior margins steeply declivous; clypeus with disc usually depressed, 

 muscle impressions distinct; face finely pubescent, clypellus protuberant, 

 longitudinally carinate, contour of its lower portion at right angle to 

 profile of clypeus. 



Thorax with pronotal width greater than transocular width of head, 

 lateral margins convergent anteriorly, disc with several callosities and 

 rugose or punctate, finely pubescent, posterior margin concave, with 

 dorsopleural carinae complete; scutellum transversely striate in apical 

 half. Forewing with or without a membrane, reduced when present, 

 surface with several wrinkled areas or nodules, veins elevated and 

 distinct, with more than four apical cells, corium with a discal plexus 

 of veins, with or without anteapical supernumerary veins to costal 

 margin. Hindwing at rest extending almost as far posteriorly as fore- 

 wing; vein R2+3 entire. Hindlegs with femoral setal formula 2:0:0; 

 first tarsomere shorter than combined length of second and third. 



Male genitalia: Pygofer well-produced and rounded apically, with 

 numerous microsetae dispersed uniformly over surface except basidor- 

 sally, without processes, but occasionally with internal folds. Plates 

 separate, length varying interspecifically compared to pygofer, grad- 

 ually tapered and with a spinelike apical projection, with numerous 

 uniformly dispersed microsetae. Style with length variable inter- 

 specifically in relation to connective, with distinct preapical lobe, 

 not or only slighdy modified apically. Connective broadly linear 

 with basal arms not divergent, keeled medially. Aedeagus symmetrical 

 with shaft short, with an unpaired median basal process and often 

 with a pair of lateral processes. Paraphyses absent. 



Female unknown. 



Specimens belonging to this genus are rare in collections. Proconobola 

 appears to be restricted to the Andes. The known generic range is 

 Ecuador, Peru and Bolivia. Proconobola is similar to Tunga in general 

 appearance. If differs in a number of characters, including its peculiar 

 male plates, the form of its styles, its more elongate connective and the 

 median ventral process of the aedeagus. It is also related to Mareba, in 

 the discussion of which (p. 63) distinguishing characters have been 

 noted. 



The lectotype of P. callidula (Jacobi) was dissected and the genitalia 

 were found to agree well with the specimen illustrated in figure 51. 

 Except for the aedeagus (fig. 52f), the lectotype of P. dubia (Schmidt) 

 has genital characters like those of P. callidula (Jacobi) except that 

 there are no lobes in the posterior membrane of the genital capsule, 

 and except that the styles^ nd connective are like P. nodosula (Melichar).
