Diagnosis. The genus is distinguished from other American stenopodaine genera by the relatively long juga which extend between the antennae, either parallel, divergent, or convergent apically; short antenniferous tubercles, just attaining the apex of head; slender profemur, lacking a row of ventral spines; lack of ramose spines located ventrally and posteriorly on the head behind the eye; and the short second rostral segment which is subequal to half the length of the first rostral segment.

Diaditus keys to Schumannia (= Ctenotrachelus ) in Blatchley (1926) based on the absence of ramose spines ventrally on the head, ocelli located on a small tubercle, and the 1st rostral segment being subequal to the length of the 2nd and 3rd rostral segment combined. Diaditus is distinguished from Ctenotrachelus by lacking the strong setigerous spines located both ventrally on the head and posterolaterally of the eyes, the slender profemora, and the lack of spines located ventrally on the protrochanter and profemur. In Ctenotrachelus there are strong setigerous spines located both ventrally on the head and posterolateral of the eyes, the profemora is incrassate, and there is a series of spines located ventrally on the protrochanter and profemora.
