Soosiulus interpolis, NEW SPECIES 
FIGURE 298, PAGE 375 
Length of both sexes 6.0 mm. Head with median length of crown from 
slightly more than six-tenths to slightly less than seven-tenths interocular 
width and approximately one-half transocular width, ocelli located slightly 
before a line between anterior eye angles, each slightly closer to median line 
of crown than to adjacent anterior eye angle, clypeus with muscle im- 
pressions distinct or not. Thorax with pronotal width approximately equal to 
transocular width of head, forewing with membrane including inner apical 
cell and apical portions of second and third apical cells. Male pygofer without 
microsetae; plates not extending nearly as far posteriorly as pygofer apex, 
with three or four uniseriate macrosetae; style extending posteriorly to a point 
less than one-half length of connective; connective sagittate in form, with a 
median keel in apical half of length; aedeagus symmetrical, regularly curved, 
in lateral view, with ventral margin regularly concave, apex slightly expanded 
with a ventroapical short acute process; paraphyses short-stalked, each of the 
rami with a slight convexity on inner margin near base. Female abdominal 
sternum VII with posterior margin gradually narrowed to a narrow median 
excision that extends almost to base. Other structural characters as in generic 
description. 
Crown, pronotum, and clavus of forewings bright orange, head with a small 
marginal spot on each side near apex and a large median basal spot in- 
cluding ocelli, black; pronotum with a median spot extending along anterior 
margin, with a slender arm extending laterally behind eye on each side, a 
small spot on each side near lateral margin on posterior half, a pair of semi- 
oval spots on hind margin, black; scutellum black except apex; forewing with 
a spot on each humeral margin connected by a narrow band along com- 
missural margin to a large transcommissural hastate marking in clavus, all of 
which are black, claval suture narrowly black from base almost to apex, the 
black line extending into corium parallel to base of inner apical cell; the 
bright orange color of clavus continuing across inner apical cell and other 
apical cells, remainder of corium translucent yellow to dull orange. 
Holotype male and a series of additional males, and one female, Taracua, 
Amazonas, Brazil, all collected in the first ten days of March (RMS). 
S. interpolis, n., sp., is closely related to S. sermunculus (Melichar) from which 
it may be distinguished by its more strongly curved aedeagal shaft in lateral 
view, and by the expansion of the inner margins of the arms of the para- 
physes at their bases. The excision of the abdominal sternum VII of the fe- 
male is similar to that of S. servulus (Melichar) but the hind margin is not pro- 
duced medially as much as in servulus.
