Psyche 
[September 
separte to base in hindwing. Hindwing with basal free piece of MA 
vertical, straight; CuP not developed. 
Male with 9th abdominal sternite reduced, transverse. Gonarcus 
not desclerotized in midline; gonocoxites well developed, widely sep- 
arated from gonarcus distally, articulating on the latter proximally; 
mediuncus greatly elongate, withdrawn into an internal pouch. 
Female lacking squamae. 7th abdominal sternite well developed. 
8th sternite produced posteriad as an elongate triangular sclerite be- 
neath fused 9th tergite + ectoprocts and the bases of the similarly 
produced 9th gonocoxites, the latter without hypocaudae or traces 
of 9th gonapophyses. Genital chamber closed by posteriad appression 
of 8th sternite beneath bases of gonocoxites. Bursa copulatrix small, 
widely confluent with genital chamber. Spermathecal duct very long ; 
spermatheca a complexly coiled tube, with enlargements and diver- 
ticula. 
Type and sole included genus: *Nosybus Navas, 1910. Previously 
known from southeast and central Africa. We have seen specimens 
from northern Angola (Malange). 
Discussion. The name of this taxon has been a continuing source 
of confusion, the early proposals of Kruger and Navas being nomina 
nuda since no included genus bore the name Sphaeroberotha. Such 
a genus was not even described until 1930 when Navas proposed 
this name for his new species Sphaeroberotha durnonti and referred 
to it as “Genus Sphaeroberothinorum” (p. 133) and “. . . de este 
nuevo genero en la tribu de los Esferoberotinos. . . .” (p. 135). We 
have examined the holotype female of this species and find that this 
insect is a member of the Berothinae so that if Navas’ action of 1930 
should be considered as a validation of a family-group name based on 
Sphaeroberotha , this name would fall into the synonymy of Berothinae.
