Etymology. The epithet “andevo” is proposed to honor the black slaves that constituted about a third of the Merina society of Madagascar during the 19th century.

Remarks. Lepidocyrtinus andevo   sp. nov. resembles other species from Madagascar ( Table 5 View TABLE 5 ). See the comparison among them in the remarks of L. iegoi   sp. nov.
