Diagnosis. Belonging in the Ptiloneuridae. Male hypandrium simple, with two distinct, posterolateral, slender, acuminate apophyses, curved inward; lacking smaller, side sclerites. Forewing M three branched, hindwing M simple. Five distal inner labral sensilla, a central placoid, flanked at some distance by a pair trichoidplacoid. Phallosome: basal struts robust, Vshaped, joined distally to the external parameres, these sausageshaped, elongate, bearing pores distally. Two pairs of endophallic sclerites, outer pair wide based, long, distally acuminate, directed outwards; inner pair strongly pigmented basally, each half with a short, blunt extension directed posteriorly. Male and female paraprocts and epiproct, and female subgenital plate, gonapophyses and ninth sternum as in species of Triplocania.
Differing from Perucania New & Thornton, and from Triplocania Roesler, in having the hypandrium simple, with posterolateral projections and lacking side sclerites. Differing from Ptiloneuropsis Roesler in lacking a triangular areola postica joined to M by a crossvein in the forewing. Differing from Ptiloneura Enderlein, Loneura Navás, Euplocania Enderlein and Timnewia García Aldrete, in having forewing M with three branches, and in having the hypandrium simple, with posterolateral projections. Differing from Loneuroides García Aldrete, in having forewing M three branched and with a smooth pterostigma, and in having hindwing M simple. Differing from Willreevesia García Aldrete, in having forewing M three branched, in having hypandrium with posterolateral projections, and in having phallosome with sausageshaped external parameres without associated sclerites, and lacking a central, three pronged sclerite.
Type species. Triplocania cervantesi García Aldrete
Etymology. The genus name is artificial, combining the root of Belize, the country where the species was collected, and “cania”, a common generic stem used in Ptiloneuridae (e. g. as in Perucania and Triplocania).
