Remarks: All the specimens labelled as “typus” by Berg and treated as syntypes by Carvalho & Webb (2005), are considered here as lectotype and paralectotypes (ICZN, art. 74.1.1). This species was originally described as Tomaspis Amyot & Serville by Berg (1879) and transferred to Mahanarva Distant by Fennah (1968: 186).

Lectotype 1729/1 lacks prothoracic and mesothoracic right legs. Paralectotype 1729/2 lacks prothoracic and mesothoracic legs. Paralectotype 1729/3 lacks metathoracic rigth tibia and abdomen.
