Johnsonita oxalida Bálint, Boyer & Pyrcz , sp. n.

( Figs 11 , 19E–F , 22G–I , 30 )

Type material. CB holotype male (will be deposited in CEP – MZUJ) in good condition, labelled as “ 2200- 2500 m, [//] la Antena, [//] SE Oxapampa (Pasco) [//] Pérou 20-10-2009 ” (dissected. gen. prep. 893/ J. Lorenc). Paratype: Peru, Huánuco, Paso Carpish 2800-3000 m, 2003.II.19. ( CB: female; dissected; gen. prep. 894/ J. Lorenc) .

Description. Wings. FW costa length: 14–15 mm (n=2), apical area of costa and outer margin is not straight resulting in a somewhat rounded shape; dorsal wing surface colouration pale violet blue, black border inner margin reaching the erection of vein M3; HW dorsal surface discal area structurally coloured; ventral FW submedial and medial pattern running parallel, submarginal area conspicuously lighter than medial and basal regions, antemargin area brown; HW medial pattern composed by ruptive band brown coloured bordered basally by a thin white line, submarginal area conspicuously lighter than medial and basal regions, antemargin area brown. Genitalia. Male valva thin with rounded costal margin flip and extremely pointed valval terminus (with valval length) and strong saccus. Female ductus thin with parallel edges but at 2/3 length divergent, no lower plate, upper plate symmetric and large with thinly sclerotized frame with a single spine. Androconia present in FW ventral surface basal are with cubital scent patch and HW dorsal wing surface medial area with black fur.

Diagnosis. On the basis of the dorsal HW surface “fur” and the ventral HW surface zigzagged pattern contrasted it is easy to distinguish the species from the congeners. The similar species J. johnbanksi is more vivid blue dorsally, the ventral wing surface submarginal areas are not so light, the medial zigzagged pattern is more ruptive and the submedian and basal area have a gleaming white scales suffusion.

Distribution. Geographical: PERU (Huánuco, Pasco) ( Fig. 30 ); spatial: recorded between 2200–3000 m a.s.l; temporal: recorded in February and October.

Etymology. The name “oxalida” is used to emphasize the type locality “Oxapampa” and the observation that the species is lighter (= “pallida” in Latin) than the putative sister species J. johnbanksi . The species name “oxalida” is freely formed Latin name and is treated as a female noun in apposition.
