Remarks: All the specimens labelled as “typus” by Berg and treated as syntypes by Carvalho & Webb (2005) are designated here as lectotype and paralectotypes (ICZN, art. 74.1.1). This species was originally described as Tomaspis Amyot & Serville by Berg (1879), transferred to Deois (Pandysia) by Fennah (1953: 357) and later placed as Deois (Deois) by Costa & Sakakibara (2002: 197). The original publication indicates that five specimens were used for the description of the species, but only three are deposited.

Paralectotype 1732/2 lacks left mesothoracic leg, tibia and tarsi of right metathoracic leg and has abdomen dissected in vials with glycerine. Paralectotype 1732/3 lacks right mesothoracic leg.
