Alisotrichia lobata Flint, 1968b, p. 43.

This species appears to belong to the typical group of Alisotrichia, although it is not closely related to any other known species. The shape of the eighth sternum and the long spine and shape of the ventromesal complex of the ninth segment are distinctive.

Male genitalia: Seventh sternum with an apicomesal process. Eighth segment with a large, rounded anterolateral lobe, ventromesal angles prolonged into sharp spines separated by a narrow mesal excision. Ninth segment with long, very slender, anterolateral processes. Tenth tergum with a pair of dorsal straplike sclerites, with ventrolateral margin sclerotized. Ventrolateral angle of ninth segment with a long, slender process; ventromesally with a ring surrounded by a hoodlike structure. Aedeagus tubular, base slightly enlarged.
