Diagnosis. Both sexes of this subspecies are immediately recognizable from all other subspecies of C. opalinus  by the lighter, chestnut upperside ground colour, and the very small HWDAbout HWD blue patch, elongated and restricted mostly to the anal area, and a lighter steely blue than in any other C. opalinus  subspecies. They are usually smaller than all the subspecies of C. opalinus  , except C. opalinus cristalinus  n. ssp., with a somewhat more acute FW apex. Female’s ductus bursae ( Fig. 11F View Figure ) is narrow and longer than all the subspecies of C. opalinus  except for C. opalinus cristalinus  n. ssp ( Fig. 11 D–E View Figure ).

Description. Head, thorax and abdomen not differing from C. opalinus  . Wings described below:

FWL: 26–29 mm, mean: 28,2 mm (n=65).

D colour: glossy chestnut, lighter basally

HWP colour: metallic steely blue

HWP shape: subtriangular, extending from postbasal area, along the outer margin of the discal cell and vein CuA1, and along the anal margin to postmedian area, generally not entering the discal cell, nor cell M3–CuA1, except occasionally for a few scales

Individual variation. In some specimens, the lightening of the chestnut colour is limited to the basal area and discal cell, in others, a majority, it spreads distally from the discal cell to the submarginal area. On the FW the transition between basal chestnut and distal brown is gradual. On the hindwing the limit between the two shades is sharper.

Etymology. This subspecies is named after its type locality, Páramo El Rosal. 

Geographic range. Páramo El Rosal  , apparently throughout the southern part of the Páramo de Batallón  massif in the Cordillera de Mérida. It has not been reported so far from the southernmost Páramo Zumbador  , nor from the north-westward Páramo La Negra. 

Altitudinal range. 2900–3050 m a.s.l.
