A new genus, Spinobala Ortiz-Tovar & Pinedo-Escatel gen. nov. , is described to accommodate S. soctonae Ortiz-Tovar & Pinedo-Escatel sp. nov and S. metapanella (Kramer, 1963) comb. nov. from the Chiapas Highlands province. The new genus can be separated from other Neobalini genera by the unique next combination of external and internal features including: (1) rounded crown with anterior and posterior margin parallel, (2) forewing with three anteapical cells and rounded apex, (3) metafemur macrosetal formula 2+2+1, (4) anal tube with a pair of stout processes, and (5) apophysis of styles with a preapical transverse carina. A dichotomous key is provided and a map of distribution for Spinobala is given, which for S. metapanella comb. nov. is newly reported in Guatemala.
