Johnsonita ianusca Bálint, Lorenc –Brudecka & Pyrcz, sp. n.

( Figs 8 , 18A–B , 23D , 30 )

Type material. CEP – MZUJ holotype male, in moderate condition (HWs broken, abdomen missing (genitalia with abdomen in microvial attached to the specimen), labelled as (1) “ ECUADOR [//] Prov. Azuay [//] Cuenca, Molleturo [//] 02.09.2003, 2600 m [//] leg. J. Wojtusiak ” (white label, printed), (2) “ Johnsonita M51 [//] Budapest 2010.IX [//] Bálint Zsolt” (white label, printed), (3) “prep. genit. 377 [//] 17.05.2016 / J. Lorenc [//] J. ianusca [//] Molleturo [//] 02. 09. 2003 ” (white label, printed). No paratype.

Description. Wings. FW length: 15 mm (holotype), FW apical area of costa and outer margin is not straigth resulting in a somewhat rounded apex; male dorsal wing surface structural colouration bright violet; dorsal FW surface black border reaching the middle of vein M3; HW dorsal surface discal area structurally blue coloured; ventral wing surface submedian area with a conspicuous discal spot, medial pattern composed by light disrupted line supplemented distally with dark spots; ventral wing surface inner margin medial area with brown scaling. Genitalia. Male valva with pointed small costal margin flip and heavily sclerotized pointed valval terminus slightly downturning in lateral view (with valval length), gnathos tip extremely thin and pointed downturning at its very final point. Androconia present in ventral FW along Cubital 2 vein as a patch in submedian area. Female not known.

Diagnosis. The species is easily distinguished on the basis of the ventral HW discal pattern, where there is a discal spot (it is missing in all other congeners); somewhat resembles in wing shape and pattern to the sympatric J. catadupa , but the dorsal wing surfaces are deeper blue ( J. catadupa are bright azure).

Distribution. Geographical: ECUADOR (Azuay) ( Fig. 30 ); spatial: recorded from 2600 m a.s.l; temporal: recorded in September.

Etymology. Dedicated to the late professor Janusz Wojtusiak (1942–2012), who was a great entomologist and our educator, mentor, Academic teacher, and showed us how to love tropical butterflies. The species name “ianusca” is freely formed by Latinising the word “Janusz” and treating it as a female noun in apposition.
