21:55); anterior border subtruncate; anterolateral borders straight, 
with irregular teeth ; the posterolateral slightly rounded ; fore and 
hind lobes rather flat; interlobal depression shallow; carinae mod- 
erately prominent, granulate. Scutellum subtriangular, much longer 
than its width at base ( c? 30:23, $ 29:23) ; lateral bordersi barely 
convex, almost straight, feebly reflexed ; disc flat, finely granulate in 
basal 2/5, more roughly so in apical 3/5; depressed at base, and 
moderately raised around depression; apex narrowly rounded. Hem- 
elytra narrow, leaving entire connexivum and parts of tergum ex- 
posed, reaching genital lobes (cf), or tergum VII (?) ; corium 
extending to suture between terga IV and V, its basolateral border 
expanded, rounded, and more or less reflexed. Abdomen longer than 
its maximum width across segment IV ( cf 90:75, 9 io 5 : $5) > lateral 
borders strongly convex in both sexes, very finely serrate, and slightly 
notched at PE angles of connexiva; genital plates (Figs. 3 — 4) 
slightly convex posteriorly, and slightly notched at spiracles in male, 
more convex and less notched in female. Color testaceous; depres- 
sion on vertex, apex of antennal segment II, basal 2/3 of III, entire 
IV, some spots on pronotum, and lateral borders of scutellum, darker, 
brown to piceous; posterolateral borders of pronotum, basolateral 
expansions on hemelytra, oval spots on terga III to VI, and round, 
callous spots on connexiva III to VI whitish; in some specimens 
posterior borders of connexiva II to VI, and R + M veins of corium, 
pinkish; ventral side testaceous, with some darker spots; hind borders 
of connexiva pink. Total length: cf 6.48 mm., 9 7-20 mm.; width of 
pronotum: cf 2.12 mm., 9 2.20 mm.; width of abdomen: cf 3.00 
mm., 9 3-40 mm. 
Aradus oviventris keys out to Aradus basalis in Parshley 2 , but it 
may be separated from the latter species by the relatively shorter 
rostrum, reaching at most to hind border of prosternum, different 
shape of pronotum (with stronger teeth), relatively shorter antennae 
(only slightly longer than head and pronotum together), and color.
