CICADELLINAE: PART 2. NEW WORLD CICADELLINI 329 
Male genitalia: Pygofer strongly produced, posterior margin regularly con- 
vex, with a number of macrosetae of almost uniform length on posterior half 
of disk. Plates slender, triangular, not extending nearly as far posteriorly as 
pygofer apex, with uniseriate macrosetae. Style extending posteriorly as far as 
or farther than apex of connective, not truncate apically. Connective variable 
interspecifically. Aedeagus symmetrical, directed posterodorsally, expanded or 
not apically. Paraphyses asymmetrical. 
Female abdominal sternum VII with posterior margin well produced and 
narrowly rounded apically, or extremely strongly produced posteriorly in a 
slender tapering process that extends as far as apex of ovipositor. Dorsal 
membrane of genital chamber partly sclerotized. Ovipositor with second 
valvulae each expanded beyond basal curvature and bearing dorsal teeth 
which are rounded at base of toothed portion, sloping and quadrate in re- 
mainder of length of row and bearing minute secondary denticles, with a 
short dorsal anteapical denticulate area and with apicoventral margin denti- 
culate, apex bluntly rounded. Pygofer with a number of irregularly arranged 
macrosetae at apex and near posteroventral margin. 
Specimens are black with median markings often present on the forewings 
in rest position. 
Specimens belonging to Pachitea Melichar have been studied from 
Venezuela, Colombia, Ecuador, Peru, and Bolivia. Pachitea has species which 
are similar in appearance to species of Diedrocephala Spinola. The males can be 
readily separated from those of Ditedrocephala in the form of the aedeagus 
which is directed posterodorsally, instead of ventrally or posteroventrally as in 
Diedrocephala. In the female, abdominal sternum VII has the posterior margin 
emarginate in Dtedrocephala, produced in Pachitea. Pachitea is also similar to 
Microgoniella Melichar in a number of characters, for example the general ap- 
pearance, the produced female seventh abdominal sternum, and the shape of 
the apex of the second valvulae of the ovipositor. But the asymmetrical para- 
physes of the male (rarely present, and then reduced and symmetrical in 
Microgontella), the more produced seventh sternum of the female and the 
larger size of Pachitea species distinguish Pachitea from Maicrogoniella. 
The present interpretation of Tettigoniella habenula Jacobi is based on a study 
of the lectotype and on a male agreeing in color with it. The holotype female 
of Tettigonia subflava Walker was studied, but I have not compared males with 
it directly. The females of the male illustrated here (fig. 266) agree with 
Walker’s holotype, and I know of no species in Venezuela other than the one 
illustrated. 
A specimen of P. subflava (Walker) from Santander, Colombia in the USNM 
was collected on coffee.
