Trichogonia vittata, NEW SPECIES 
FIGURE 17 
Length of male 8.7 mm, of female 8.3-8.6 mm. Head of male with median 
length from six-tenths to three quarters interocular width and from slightly more 
than one-third to more than four-tenths transocular width, median length of 
head of female from slightly less than one-half to six-tenths interocular width and 
from less than one-third to slightly less than four-tenths transocular width, ocelli 
located on a line between anterior eye angles, antennal ledges in lateral aspect 
without a longitudinal fovea, carinate dorsally, each with anterior margin 
slightly oblique. Thorax with dorsopleural carinae oblique and complete. Fore- 
wing subhyaline with dark areas as described below, fourth apical cell petiolate, 
its base much more proximal than base of third apical cell; first posterior tar- 
somere with length greater than combined length of second and third tar- 
someres, microsetae on its ventral surface arranged in two longitudinal rows, 
with additional finer microsetae between and above the rows. Female with 
second valvulae of ovipositor with approximately nine weak rounded teeth on 
apical third of dorsal margin. Other structural characters as in generic descrip- 
tion. 
Color of dorsum sordid yellow to tan, the wings translucent tan, crown of head 
with a pair of longitudinal stripes through ocelli (occasionally interrupted), an- 
terior margin, a pair of irregular longitudinal stripes across disk and one on each 
lateral margin of pronotum, basal angles and apex of scutellum, commissural 
margins, claval apex, a vitta of variable extent along claval suture, costal, apical, 
and mesal margins of corium narrowly, a diagonal discal marking (occasionally 
joined to commissural margin beyond apex of clavus) of forewings, black; venter 
tan with at least apex of clypellus black. One male specimen lacks the paired vit- 
tae of the crown and has a median vitta instead; it also has the vittae of the fore- 
wings broken into irregular spots. 
Holotype female, Bogota, Colombia (L. Richter), four additional females and 
two males, same data (NCS). Holotype on indefinite loan to UNSM. 
T. vittata, n. sp., differs from other species of the genus in color and can be dis- 
tinguished by the characters used in the key, above.
