Trioza crinita n. sp. 
Fig. 22 
Length to tip of folded wings 3.5-4.25 mm. 
color: General color dark brown with legs 
and margins of most sclerites buff. Genal 
processes white, black tipped. Forewings 
evenly fumate. Many females much less pig- 
mented, of a general buff color. Granular wax 
deposit prominent on many specimens, 
especially along sides and on first abdominal 
tergite. 
structure: Body moderately robust with 
sparse, short, stiff pubescence, surface shin- 
ing, finely rugulose. Head large, slightly 
narrower than mesoscutum. Vertex strongly 
impressed discally, caudal margin sharp, 
raised, smoothly rounded down anteriorly. 
Genal processes conical, blunt, scarcely di- 
vergent, 0.8 as long as vertex. Antennae twice 
as long as width of head. Eyes large. Post- 
ocular areas large. Pronotum strongly de- 
pressed below plane of vertex. Forewings 
large, 2.5 times as long as wide, broadly 
rounded apically, membrane set with very 
small points except along veins; Rs long, 
sinuate, marginal cells equal. Hind wings 
thickly set with large points. Metatibiae with 
serrate basal carina, 1 outer and 3 inner apical 
spines. 
Male genitalia large. Proctiger with small 
apical epiphysis, very broadly produced 
caudad, with marginal fringe of very large 
setae. Forceps shorter than proctiger; in 
lateral view slender, slightly enlarged before 
apex then caudal margin oblique to blunt 
apex; in caudal view stout, nearly straight 
except incurved and black at tips, touching 
basally; in dorsal view tips blunt. Aedeagus
