Dyscophellus australis Grishin, new species

Definition. This new name is proposed for the taxon that Evans (1952) misidentified as Dyscophellus ramusis damias . Austin (2008) suggested that it is a species-level taxon due to genitalic differences, with which we agree. The description of it is given by Evans (1952: 150) and it keys to D.4.9.(c[sic! recte d]). In brief, smaller than D. ramusis (Stoll, 1781) (type locality Suriname), forewing length about 25 mm in males and 30 mm in females (not 30 and 35); wings ochreous-brown (not reddish-brown) with darker-brown spots, most of which with paler centers both above and below; hindwing with outer margin convex and angled at vein CuA 2; harpe in male genitalia terminally broader and divided, inner edge not folded over. The specimen in the best condition from the Evans series is selected as the holotype, a male from Paraguay: Sapucay in the Natural History Museum, London, UK (BMNH), illustrated in Fig. 2c , and the rest of the series curated by Evans (8 ♂♂ and 2 ♀♀) are paratypes, from Paraguay and Brazil: Espírito Santo, Rio de Janeiro and Goiás. Type identification labels will be mailed to curators of the collection to be placed on these specimens.

Type locality. Paraguay: Sapucay.

Distribution. The species is known from Southeast Brazil and Paraguay.

Etymology. The species is the southernmost representative of the Dyscophellus species that are close relatives of D. ramusis . The name is a masculine adjective.
