Wings short, with rounded apices; stems of R and M adjacent 
but separate to base, or bases of these veins fused in forewing. Re- 
current humeral vein not present. Hindwing with basal free piece 
of MA transverse, sinuate; with base of CuP present, fusing with 
iA. 
Female lacking squamae. 7th abdominal sternum well developed. 
8th sternum reduced to thin cresentic sclerite in midline, or absent. 
9th gonocoxites with minute or small hypocaudae; remnants of 9th 
gonapophyses produced anteriad as slender bands along ventrolateral 
margins of genital chamber, the gonapophyses affecting the closure 
of the genital chamber by pressing anteriomesad against convex mem- 
branous lobe occupying the usual position of the concave 8th gono- 
coxites behind region of 8th sternum. Structure of bursa copulatrix 
unknown. Spermathecal duct elongate; spermatheca complexly 
coiled, with enlargements and diverticula. 
Included genera: *Rhachiberotha Tjeder, 1959 ; Mucroberotha 
Tjeder, 1959. Both from Rhodesia. 
Discussion. The manner of the closure of the genital chamber 
described above is based on our examination of specimens of the two 
species of Rhachiberotha and this may not be quite correct for Mucro- 
berotha. Judging from Tjeder’s figures (1959: figs. 253K-253M), 
weakly sclerotized 8th gonocoxites ( “postgenitale” ) seem to be present 
in this latter genus and the closure of the genital chamber may not 
differ appreciably from the manner described above for Cyrenoberotha.

Description. Berothids with head and mouthparts very short; 
vertex with lateral tubercles well developed and with area of median 
tubercle raised as a larger, convex swelling which is not distinctly 
tuberculate, all swellings bearing tufts of long setae; head capsule 
moderately inflated behind eyes. Pronotum quadrate, lightly con- 
structed, not deflexed laterally. Forelegs without raptorial modifica- 
tions. 9th abdominal tergite fused to ectoprocts, the latter lacking 
cereal calluses and trichobothrial setae. 
Wings short, with rounded apices; recurrent humeral vein not 
present. Stems of R and M fused in forewing, closely adjacent but
