Etymology.

The genus name " Nuvol " is a masculine noun meaning “cloud” in Catalan; the species name " satur " is a Latin adjective (masculine form) meaning "deep or full", as applied to color (R. A. Pantaleoni, pers. comm.). The species name refers to the more intense coloration of the diffuse markings on the wings of the species, as compared with N. umbrosus .

Diagnosis.

The most notable features that distinguish N. satur from N. umbrosus are the head and pronotal markings, markings on the abdomen, wing size, and wing markings, as follows: (1) The head and prothoracic markings of N. satur are red and diffuse, whereas those of N. umbrosus are brown and longitudinally striped; (2) The wings of N. satur are 14.8-15.8 mm long, slightly shorter than those of N. umbrosus (17.0 mm); and (3) Although both Nuvol species express some degree of suppressed forking in the terminal veinlets of the forewings and hindwings, N. satur has a much greater degree of suppression than N. umbrosus . Almost none of the terminal veinlets of the N. satur wings are forked, whereas only a small proportion of the veinlets on the posterior margin of the N. umbrosus wings are unforked. Finally, (4) the wing markings of N. satur are considerably more pronounced and in a different pattern than those of N. umbrosus (Fig. 7 ).

Description.

Provided by Tauber and Sosa 2015: 144-150 (as Nuvol umbrosus ). Note: In the description, we neglected to mention the length of the antennae; they measured 28.6 and 31.5 mm, over twice as long as the wing length (13.8 mm). The antennal length for N. umbrosus is unknown.
