Males with spicules on anal promontory accompanied by a thick, strong gubernaculum, genital papillae in three simple preanal papillae, of which the first is very large, adanal pair and a simple postanal at base of caudal appendage. Blattophila incomptus sp. n. has short stoma with plate and two teeth, large amphidia, excretory pore near base of the basal bulb, nerve ring located at anterior end of the corpus, dilated intestine at anterior end, vulva in half of body, vagina directed anteriorly.
