52. Genus TIPUANA MeELICHAR 
Ficures 270-274 
Type-species: Tipuana expallida, new species. 
Length 7.6-10.4 mm. 
Head moderately to well produced, median length of crown varying from 
six-tenths of, to one-tenth greater than interocular width, and from slightly 
less than four-tenths to six-tenths transocular width, anterior margin varying 
interspecifically from narrowly to broadly rounded in dorsal view, ocelli 
located behind a line between anterior eye angles, variable with relation to 
relative distance from median line of crown and adjacent anterior eye angle, 
crown shallowly concave, without sculpturing or setae, lateral clypeal sutures 
extending onto crown and attaining ocelli; antennal ledges not or only slightly 
protuberant, in lateral view with anterior margins varying from convex to 
rectilinear; clypeus usually flattened (convex in 7. albula (Osborn)), muscle 
impressions distinct (albula) or not, face without pubescence, transclypeal 
suture incomplete, clypellus not produced, contour of its lower portion usually 
more nearly horizontal than remainder of face (exception: albula). 
Thorax with pronotal width greater than transocular width of head, lateral 
margins convergent anteriorly, dorsopleural carinae complete, posterior 
margin concave, disk without transverse rugae, not pubescent; scutellum not 
transversely striate behind transverse sulcus. Forewing without a membrane, 
veins usually indistinct at base of anteapical cells, apex of outermost ante- 
apical cell attaining base of outer apical cell, with four apical cells of which. 
second is narrowed apically and fourth with its base more proximal than base 
of third; texture opaque or translucent, without sculpturing, apical margin 
slightly concave; forewings of female in rest position exceeding apex of ovi- 
positor. Hindleg with femoral setal formula 2:1:1; length of first tarsomere 
greater than combined length of two more distal tarsomeres and with two 
parallel rows of small setae on plantar surface. 
Male genitalia: Pygofer moderately produced, posterior margin varying 
from narrowly to broadly convex, setae variable in size, located on posterior 
half, pygofer processes absent. Style extending posteriorly beyond apex of con- 
nective, usually with preapical lobe (not extending as far as apex of connective 
and without a preapical lobe in an undescribed species), narrowly convex 
apically (exception: truncate in 7. chirensis, n. sp.). Connective Y-shaped with 
arms widely divergent (exception: chirensis). Aedeagus symmetrical or not, with 
one or more apical processes and with or without a ventral process on shaft near 
its base. Paraphysis or paraphyses present, symmetrical or not. 
Female abdominal sternum VII with posterior margin transverse, shallowly 
emarginate medially, the emargination bearing a short triangular process in 
some species. Ovipositor with second valvulae expanded throughout length 
beyond basal curvature, the expanded portion with numerous uniform sloping 
quadrate dorsal teeth, each bearing minute secondaries, with anteapical dor- 
sal and posteroventral denticles. Pygofer slender, narrowly convex postero- 
dorsally, with numerous macrosetae on posterior and posteroventral portions 
(valvulae II not illustrated, but very similar to illustration for Pachitea (fig. 
267)).
