Remarks: Both the specimens were labelled as “typus” by Berg and mentioned as syntypes by Carvalho & Webb (2005: 58). This species was originally described as Tomaspis Amyot & Serville by Berg (1879) and subsequently was synonymized with Deois (Deois) terrea (Germar) by Sakakibara (1979: 12). Are considered here as lectotype and paralectotype (ICZN, art. 74.1.1).

Paralectotype 1733/2 lacks both mesothoracic legs and left forewing.
