Docophorus acutipectus, Kell. 
The basal plate is much longer (3:2) than, though hardly so wide as, 
the exserted portion of the apparatus. The paramera are broad, especially 
at the base which, on the inner side, is slightly doubly concave. The anterior 
and posterior angles of the base are distinct though rounded. The sulcus 
of articulation with the endomera is neither deep nor extensive. Its 
superior and inferior edges are parallel. Each parameron is a little broader 
medianly than at the base, and beyond the middle contracts rather sharply 
to a point. The ventral hair is at three-fifths. The sides of the paramera 
are continuously curved, and the outer is markedly convex. 
The endomera are triangular in shape, convex externally, and doubly 
concave internally below. The median clear area is thus constricted at a point

beyond three-fourths. The basal uncus of the endomeron is well developed 
and closely adherent to the base of the parameron. Apex of endomera 
blunt, recurved and thickened, as is likewise the whole outer edge. 
There are about seven pre-apical ventral hairs in two rows on each 
endomeron. 
The hypomeron is very broad and short. It is applied to the penis at 
the level of the apices of the endomera. 
The telomera are particularly distinct. Each consists of a narrow
