Drusilla? unicolor ( CAMERON, 1950) , comb. nov:

Zyras unicolor CAMERON, 1950: 126 .

Type material examined: Holotype ♂ [teneral; in poor condition]: “Holotype / Malaya , Kuala Lumpur, January 1931., H.M. Pendlebury / A. unicolor Cam. Type / M. Cameron. Bequest, B.M. 1955-147.” ( BMNH).

Comment: In the original description, which is based on a unique male from “ Kuala Lumpur ”, CAMERON (1950) stated that this was a “somewhat anomalous species” somewhat resembling “ Astilbus ” (now a junior synonym of Drusilla ), but with “the neck much broader”. As can be inferred from his identification label attached to the holotype, he had originally planned to assign the species to Astilbus , but eventually decided to describe it in Zyras . The external characters suggest that the holotype belongs to Drusilla rather than to Zyras . Since the specimen is teneral and in generally poor condition, it was not dissected. Mature specimens are presumably of significantly darker coloration.
