Diagnosis.
Taygetis servius
stat. n. can be distinguished from
Taygetis fulginia
stat. r. and
Taygetis rectifascia
by the following characters: forewing rounded at the apex; dorsal wings light brown without any suffused dark brown bands along the outer margin; ventral hind wing with the proximal border of the submarginal band and post discal line straight and regular, forming a 2 mm wide creamy white fascia. The base of the gnathos presents a pointed ventral projection, as in
Taygetis rectifascia
and
Taygetis fulginia
, but differs from
Taygetis rectifascia
by the absence of the claw-shaped bifid valva apex, and from
Taygetis fulginia
by its stouter valva, with a shorter but wider distal projection of the valva. In additional,
Taygetis servius
is considerably smaller than the other species treated in the present paper.

Distribution
(Fig. 8).
Taygetis servius
is known from Baixo
Guandu
(
Espirito
Santo), and from
Jitauna
(Bahia). It should also be present in Minas Gerais (see below).
Taxonomic comments.
Taygetis servius
stat. n. was described from an unknown number of specimens from Minas Gerais, Brazil, as a form of
Taygetis rectifascia
(Weymer, 1910: 187). Although clearly recognized as such, the illustration of
Taygetis servius
(Weymer, 1910: pl. 46, fig. c [3]) is placed in another plate, separated from the rest of the illustrations of
Taygetis rectifascia
and its forms (Weymer 1910: pl. 45, fig. a [1-2]). The description and the illustration matches exactly a series of five specimens from the states of
Espirito
Santo and Bahia, Brazil, deposited at the DZUP. Wing shape and pattern, also acknowledged by Weymer, and examination of the genitalia confirms it as a distinct species. The type specimen (or specimens) of
Taygetis servius
is missing, however, type specimens of other species of
Taygetis
described by Weymer in the same fascicle of Die Gross-Schmetterlinge der Erde are housed at the SMT and ZSM collections (i.e.
Taygetis mermeria
f. crameri (Weymer, 1910), at SMT, and
Taygetina banghaasi
(Weymer, 1910), at ZSM). However, previous and recent searches for type specimens carried out by G. Lamas, O.H.H. Mielke and the curators of the above cited collections did not produce any specimens (
Nekrutenko 2001
).
