4D3E87892A5D2C7FB8E7C28CFDBCE45B.taxon	diagnosis	Diagnosis. Tosta pseudospeculum sp. nov. resembles most Tosta tosta Evans, 1953 but can be distinguished by its wider wingspan, the darker upperside wings with bands less marked than in T. tosta, ampulla separate from harpe and highly modified in a process with the distal portion dilated and serrated, and lamella antevaginalis with two spine-like well sclerotized projections extending laterally.	en	Siewert, Ricardo Russo, Mielke, Olaf Hermann Hendrik, Casagrande, Mirna Martins (2015): Tosta Evans, 1953 (Lepidoptera: Hesperiidae): a new species from northeast Brazil, first description of the female of Tosta tosta Evans, 1953, and placement of the genus within Achlyodini.

Thorax: dorsally dark brown, ventrally brown; legs brown. Forewing: male 24 – 25.5 mm (Holotype 25 mm), average length = 25 mm (n = 3); female 26 mm (Allotype). Upperside (Figs 1 and 3): ground color dark purple-brown; basal, discal and postdiscal bands dark brown extending from costa to anal margin; submarginal area lighter than ground color; no costal fold. Female as in male, but lighter and with bands more evident. Underside (Figs 2 and 4): ground color dark brown, paler distally; pale brown speculum covering about one-half from anterior portion of discal cell to anal margin and extending until two-thirds to tornus with a tuft of dark long hair-like scales originating from the base of the wing. Hind wing: costa modified, resembling a hump that covers the forewing speculum. Upperside (Figs 1 and 3): ground color dark purple-brown. Underside (Figs 2 and 4): ground color dark brown; discal and postdiscal bands darker. Female as in male, but lighter and with bands more evident. Abdomen: dorsally dark brown, ventrally brown. Female with no gland at 7 th tergite. Male genitalia (Figs 9 – 13): uncus triangular dorsally, curved ventrally, with two dorsal projections; tegumen squared dorsally; valva squared, ampulla separate from harpe and highly modified in a process with the distal portion dilated and serrated, harpe with a spine-like process curved inwards; aedeagus cylindrical, coecum thin and slightly bilobed, a group of small spines at the distal end of aedeagus, cornuti absent. Female genitalia (Figs 19 – 20): eighth tergite rectangular; papilla analis with postapophysis about the same length as the ductus bursae; sterigma formed by a a lamella antevaginalis with two well sclerotized projections extending laterally and by a broad and rectangular lamella postvaginalis; ductus and corpus bursae totally membranous.	en	Siewert, Ricardo Russo, Mielke, Olaf Hermann Hendrik, Casagrande, Mirna Martins (2015): Tosta Evans, 1953 (Lepidoptera: Hesperiidae): a new species from northeast Brazil, first description of the female of Tosta tosta Evans, 1953, and placement of the genus within Achlyodini.
