from crown to face, ocelli located slightly behind a line between anterior eye 
angles, each closer to adjacent eye angle than to median line, crown with a 
broad shallow median depression, without sculpturing or with lenticular im- 
pressions, lateral clypeal sutures extending onto crown and attaining ocelli; 
antennal ledges not protuberant, in lateral view with anterior margins slight- 
ly oblique and almost rectilinear; clypeus broadly flattened medially, muscle 
impressions not very distinct, transclypeal suture entire, clypellus with weak 
pubescence apically, in profile abruptly curved posteroventrally in its apical 
two-thirds. 
Thorax with pronotal width slightly less than transocular width of head, 
lateral margins slightly divergent posteriorly, dorsopleural carinae complete, 
posterior margin concave, surface transversely rugulose in posterior half, not 
pubescent; scutellum weakly transversely striate in posterior half. Forewing 
with membrane including all of apical cells, veins elevated and distinct, with 
four apical cells, the base of fourth not more proximal than base of third, 
without an anteapical plexus of veins, texture coriaceous and without 
sculpturing or weakly punctate; forewings of female in rest position exceeding 
apex of ovipositor. Hindleg with femoral setal formula 2:1:1, length of first 
tarsomere exceeding combined length of two more distal tarsomeres, with two 
parallel longitudinal rows of small setae on plantar surface. 
Male genitalia: Pygofer strongly produced and truncate apically, macro- 
setae short, parallel to posterior margin and on posteroventral margin. Plates 
very short, triangular, not extending nearly as far posteriorly as pygofer apex, 
with multiseriate macrosetae. Style very short, broad, not extending as far 
posteriorly as apex of connective, without preapical lobe, apex irregular in 
outline. Connective Y-shaped, the arms strongly divergent but short, with a 
strong keel. Aedeagus slender, bifid basally, bilobed apically. Paraphyses ab- 
sent. 
Female abdominal sternum VII with a conspicuous elongate process arising 
from ventral surface near base, extending posteriorly much beyond posterior 
margin of sternum VII, which is concave medially, strongly convex laterally, 
and partially telescoped beneath sternum VI to the extent that in dried 
specimens only the lateral lobes and the median process are visible. Dorsal 
membrane of genital chamber without sclerites. Ovipositor with second 
valvulae each broadened beyond basal curvature, with dorsal margin convex 
and bearing sloping primary teeth, each with small secondary teeth, except a. 
short apical portion which, like the apicoventral margin, bears minute denti- 
cles. Pygofer with few short anteapical macrosetae and a few near upper por- 
tion of caudoventral margin. 
Tettiselua, new genus, is known only from the type-species of which 
specimens have been studied from Ecuador and Peru. Tettiselva is similar to 
Xaruma Melichar in the form of the pygofer and the short plates of the male, 
and in the produced sternum VII of the female, but the relationship is 
probably not nearly as close as that between Zaruma and Apulia Distant.
