DISCUSSION Generic placement - Wing shape, colouration and markings immediately suggest the placement in Paraspiculatus. Certain taxa of genus Denivia Johnson, 1992 (type species: Thecla deniva Hewitson, 1874) somewhat resemble Paraspiculatus species. However, Denivia is typified by the apomorphy of the male androconial pouch situated along the vein 1A+2A on the hindwing ventrum. Likewise, some species of the genus Lucilda d'Abrera et Bálint, 2001 (type species: Thecla crines Druce, 1907) also resemble to the relatives of Thecla orobia but the female genitalia of these taxa are qualitatively distinct. Characters - Lengths of the costal, distal and anal margins of the fore wing were measured solely on male specimens of P. oroanna sp. n. (holotype, BMNH), P. orocana (Druce, 1912) (holotype male, deposited in the BMNH), P. orobiana (Hewitson, 1867) (male, Peru, Chanchamayo, coll. König No. 260, Naturhistorisches Museum, Wien) and P. orobia (Hewitson, 1867) (male, Peru, Puerto Maldonado, coll. König No. 255) and P. hannelore Bálint et Moser, 2001 (paratype male, HNHM). Ratios were derived for (1) costal margin/distal margin and (2) anal margin/distal margin. Mean ratios of each specimen for each of (1) and (2) were then calculated (Table 1). Although comparisons of these single specimens are statistically not reliable, the mean venal margin/distal margin ratio for P. oroanna strikingly contrasts of the other species measured. This suggests that peculiar wingshape is likely a useful taxonomic feature among larger samples of these congeners. Identification - The holotype specimen was curated as "Thecla sp. n.?" in the BMNH drawer containing representatives of the genus Paraspiculatus. This is documented by d' Abrera (1995, /. c). P. oroanna has been already placed in a key constructed for the identification of Paraspiculatus species recognized by Bálint & Moser (2001: 252). This key with some modification is presented here for the identification of P. oroanna: Table 1. Measurements of Paraspiculatus oroanna, P. orobiana and P. orocana.
