structure as figured; aedeagus, especially, 
different from usual type. 
Holotype male, Palau Islands: Ngarum- 
sukan-Kaishar, Babeldaob, August 14, 1939- 
Type returned to Esaki. 
Trioza indigena n. sp. 
Fig. 6 
Length to tip of folded wings, 3.25 mm. 
Color: Entire dorsum brown, including dor- 
sal portion of folded wings, except for medial 
yellow spot on pronotum extending as paler 
line onto vertex and prescutum. Ventral half 
of body much lighter brown to green. 
Structure: Generally pubescent. Head nar- 
rower than thorax. Vertex deeply emarginate 
cau dally, prominent discal impression each 
side of medial suture, at sides smoothly con- 
tinuous with genae, small protuberances over 
median ocellus. Antennae far down on genae 
below line of ocellus, genal processes beyond 
antennae small, divergent, conical. Antennae 
slender, 2.5 times as long as width of head. 
Thorax rather flat for genus. Pronotum verti- 
cal, depressed slightly below plane of vertex. 
Forewings bluntly angulate, 3 times as long 
as wide, maculate as shown in Figure 6; Ri 
very short, Rs arched to costa, marginal cells 
small, equal. Metatibiae with serate basal 
Carina, 1 outer and 3 inner very large apical 
spines. Metacoxae somewhat produced an- 
teriorly, meracanthi large, sharp. 
Male genital segment small. Proctiger 
strongly produced caudad. Forceps slightly 
longer than proctiger; in lateral view slender, 
somewhat sinuate to black apex (see Fig. 6b), 
in caudal view tapering from broad base, 
slightly arched, apices not touching. Female 
genital segment large; dorsal valve slightly 
longer than ventral, both slender, nearly 
straight, acute; tips blunt, brown.

Holotype male, allotype female, 7 male and 
2 female paratypes, Caroline Islands: Sanka- 
kuyama-Kolonia, Ponape, July 15, 1939. 
Type in author’s collection. 
This very distinctive species forms small 
galls on the leaves of Elaeocarpus Kusanoi 
Koidzumi, an endemic tree of Ponape. Dr. 
Esaki has suggested that perhaps it represents 
a distinct genus but, although it is markedly 
different from other species of Trioza known 
from the area, it fits well within the generic 
limits.
