Taxonomic history

Hesperia gerasa was described by Hewitson (1867) based on an unspecified number of specimens from Montes Áureos, [Municipality of Centro de Guilherme], Maranhão, Brazil. Hesperia gerasa was transferred to Goniloba Westwood, 1852 ( Herrich-Schäffer 1869), Pamphila Fabricius, 1807 ( Kirby 1871), and Proteides Hübner, [1819] ( Mabille 1878) . Mabille (1883) described Proteides porius based on an unspecified number of specimens from South America. Subsequently, Mabille (1889) described Proteides subcordatus based on an unspecified number of specimens from Chiriquí, Panama. After realizing that P. subcordatus was a homonym, Mabille (1891) designated Proteides milo as a new name for the species.When Godman (1901) proposed Orphe , Hesperia gerasa was transferred to this genus, and both species described by Mabille were synonymized with H. gerasa . Mabille (1904) transferred Proteides porius to Orphe , and this name was treated as a junior synonym of O. gerasa by Evans (1955).

Etymology

Not informed by the author.

Diagnosis

FW length: male, 20–22 mm; female, 22–23 mm. The male of this species superficially resembles P. pyrex ; however, it can be easily distinguished from it by the stigma. The female is distinguished from P. pyrex by the lilac scales, whereas P. pyrex has dark yellowish scales in discal to anal areas of the VHW. Male and female wings ventrally with lilac scales in apical and submarginal areas ( Figs 1B, D ). Stigma with a single row of grey scales along its edge in CuA 1 and 2A ( Fig. 3A ). Male genitalia ( Fig. 4 ) with anterior projection of saccus shorter than the length of tegumen + uncus; uncus truncated posteriorly, with two distal tips sclerotized; gnathos shorter than uncus, with dark punctuations distally; valva, harpe with a dorso-distal spined bifid projection, ampulla directed dorsally; aedeagus with tiny and a few cornuti. Female genitalia ( Figs 6A–B ) with lamella antevaginalis formed by two sclerotized lateral plates projected towards and exceeding the lamella postvaginalis; median projection of lamella antevaginalis not reaching the lamella postvaginalis.

Comments

In some males, the hyaline spot in CuA 1 –CuA 2 on FW is absent, a small spot still appears in M 1 –M 2. In females, the spot in M 1 –M 2 on FW is always present. In males, the two hyaline spots on FW in the discal cell are sometimes fused, forming a single spot, whereas in females the discal cell always has a single spot.

Type material

Hesperia gerasa was described and illustrated by Hewitson (1867) based on an unspecified number of specimens from Montes Áureos, [Municipality of Centro de Guilherme], Maranhão, Brazil, deposited in the Belt collection. One syntype male, found in NHMUK, has the following labels: / Type / Type / red label without information / Maranham [Maranhão, Brasil] Hewitson Coll. 70-69. Hesperia gerasa, Hew. /. Thus, in order to stabilize the identity of this species, this syntype is designated herein as the lectotype, adding the following two labels: / LECTOTYPUS / Lectotype Hesperia gerasa Hewitson, 1867 Suênia-Bastos, Mielke & Casagrande det. 2024/.

Proteides porius was described by Mabille (1883) based on an unspecified number of specimens from South America, but the type could not be found.

Proteides subcordatus was described by Mabille (1889) based on an unspecified number of specimens from Chiriquí, Panama, firstly deposited in the Staudinger collection, then deposited at the MfN now. One syntype male, found in MfN, has the following labels: / Prot. Subcordatus HS ♂ / Coll. Staudinger / Lectotypus / Chiriqui / Perichares gerasa HW. / 127: 1 /. Thus, in order to stabilize the identity of this species, this syntype is designated herein as the lectotype, adding the following two labels: / LECTOTYPUS / Lectotype Proteides subcordatus Mabille, 1889 Suênia-Bastos, Mielke & Casagrande det. 2024/.

Host plants

The immatures feed on Arecaceae Schultz Sch. and Poaceae (R.Br.) Barnh. According to Moss (1949), the immatures in Pará ( Brazil) feed on açaí ( Euterpe Mart. *), though the species is not identified. Janzen and Hallwachs (2009) observed immatures feeding on Elytrostachys clavigera McClure.
