Culumana picchua Domahovski 2024, comb. nov.

Culumana picchua (DeLong, 1979) comb. nov. (Fig. 3) Curtara (Sinchora) picchua DeLong, 1979: 236. Material examined. Holotype male, “ Machu Picchu \ PERU XI-25-67 \ D. M. DeLong ”, “ OSUC 0169177 ”. Remarks. Curtara picchua was described based on a single male specimen from Peru and placed in subgenus Sinchora due to the lack of apodemal processes on the aedeagus. This species strongly differs from the type-species of Curtara due to its crown with transverse striations, head and pronotum without dark punctures, forewings without mottled dark maculae, and outer discal cell lacking the inner apical accessory vein. Curtara picchua is similar to several species of Culumana as follow: coloration reddish-brown with black maculae near anterior margin of pronotum, m-cu1, m-cu2 and apex of anal veins of forewings (Fig. 3); pygofer strongly tapered apically (DeLong, 1979: 234, fig. 40); subgenital plate ligulate (DeLong, 1979: 234, fig. 39); blade of style undulate with apex rounded (DeLong, 1979: 234, fig. 38); aedeagus with well developed preatrium and dorsal apodeme, shaft long with one subapical process and pair of apical processes. Besides that, C. picchua is very similar to Culumana pilana (DeLong, 1972b: 410, figs 21–25) and Culumana dualana (DeLong, 1979a: 106, figs 6–10), both from Peru. Based on these features, Curtara picchua is here transferred to Culumana. In the key to males provided by DeLong (1984), the species will key out as C. dualana, at step 13, but can be separated by the longer apical processes of the aedeagus and absence of a short pair of subapical lateral processes.
