Orthoderella Giglio-Tos, 1897

Piza (1962) described Tithrone major on the basis of six males and one female (Fig. 6 a–b), all with type locality in Piracicaba, São Paulo state, Brazil (all deposited at ESALQ). No holotype was designated; thus, they are all syntypes. At first glance, it resulted obvious that these specimens were attributable to Orthoderella (Photininae) instead to Tithrone (Acanthopidae-Acontistinae), as originally classified by Piza (1962). Furthermore, a detailed comparative analysis of the external morphology of these individuals, including the male genitalia (Fig. 6 c–d), allowed their recognition as Orthoderella brasiliensis Roy & Stiewe, 2011, recently described from southern Brazil (Roy & Stiewe 2011). Both T. major and O. brasiliensis also exhibit similar distribution. Consequently, the following nomenclatural changes are introduced:

Orthoderella major (Piza, 1962), n. comb. Tithrone major Piza, 1962

= Orthoderella brasiliensis Roy & Stiewe, 2011, n. syn.

Piza (1962) did not select any particular specimen from his type series as the holotype of T. major . Therefore, we here designate as a lectotype one male specimen (Fig. 6 a) whose label contains the following information: Brasil, São Paulo, Piracicaba; abril-1951 (4/51), I0075.
