Type species: Acanthocyrtus bicolor Yosii, 1965

Type locality: Wulai , Taiwan, China .

Diagnosis: The genus is characterized by eight + eight eyes, pointed scales with coarse striations present on body but absent on dens, presence of dental spines, clavate tenent hair, bidentate mucro with a basal spine and larger subapical tooth, two–three–two bothriotrichia on Abd. II –IV, slightly modified accessory microchaetae of bothriotrichial complex, and a row of anterior eyebrow-like macrochaetae on Abd. IV. As a member of Willowsiini sensu Yoshii (1989) by the absence of scales on dens, it resembles Homidia in dorsal cephalic chaetotaxy, eyebrow-like macrochaetae on Abd. IV, smooth setae E and L 1 on labial base and larger subapical tooth on mucro; it differs from Homidia by the presence of scales on the body; it differs from the other seven genera of Willowsiini in the presence of dental spines, and also differs from members of Seirini in the absence of dental scales.

Etymology: The new genus is named after Homidia , one genus widely distributed in China, for the many shared features.
