Fonsecaiulus sciotus, NEW SPECIES 
FIGURE 626 
Length of male 5.5-6.1 mm, of female 6.1 mm. Head with median length of 
crown varying from slightly less than two-thirds to slightly more than three- 
fourths interocular width and from slightly less than four-tenths to slightly 
less than one-half transocular width. Male pygofer without processes, style 
foot-shaped at apex; aedeagus broadened apically in lateral view and ob- 
liquely truncate, with an unpaired dorsoapical process and a pair of slender 
tapering parallel processes arising near midlength of apical margin and ex- 
tending dorsally; paraphyses short-stalked, with rami each bearing a short 
branch near midlength and a shorter one at apex. Female abdominal sternum 
VII with posterior margin broadly convex, genital chamber with a pair of 
elongate crescentiform processes in dorsal wall. 
Color of dorsum chestnut-brown to reddish, median yellow vitta of crown 
extending onto pronotum and narrowing posteriorly, scarcely attaining 
scutellum, with a pair of much narrower longitudinal narrow yellow vittae on 
pronotum; forewing with a broad irregular yellow spot in basal half of clavus; 
with three (at most) pale spots in corium near claval suture in its apical half, 
the spots confluent in some specimens; face, pleura, venter, and legs, yellow. 
Holotype male, Loreto, Misiones, Argentina, December 14, 1931 (A. A. 
Ogloblin) and one female, same data except December 3, 1931 (USNM). One 
male, Puerto Bemberg, Misiones, Argentina, January 12-29, 1945 (Golbach 
and Hayward) (Instituto Miguel Lillo collection). Two females, S. Antonio de 
Barra, Prov. of Bahia (Ch. Pujol) (MMB). 
The male genitalia of F. sctotus, n. sp., and the color pattern used in the key 
will separate sciotus readily from other species of the genus.
