Marcelonemobius Cadena-Castañeda & Rodríguez & Navarrete-Heredia 2019, n. gen.

Marcelonemobius n. gen.

Diagnosis: Medium size eyes (not as prominent as for most genera of the Nemobiinae), without a pigmented band on the edges. Fore wings short (in both sexes), reaching at most the fifth abdominal tergite, dorsal field with parallel veins, with few intercalar veins and without stridulatory apparatus. Fore tibia without tympana; hind tibia with four dorsal spurs on each side; three apical spurs on each side, being the middle spur largest to outer surface and the superior spurs is the largest to the inner surface. Phallic complex. Pseudepiphallus elongated, apical portion with a pair of lateral, in-curved sharp projections and with additional basal prolongation smaller and rounded in dorsal view; pseudepiphallic apodeme poorly developed.

Etymology: Name after the Brazilian orthopterist Dr. Marcelo Ribeiro Pereira as a recognition for his contributions to Neotropical Nemobiinae.

Type species: Marcelonemobius mutum n. sp. by monotypy and original designation.

Comparison: This new genus resembles Kevanemobius Bolfarini & de Mello, 2012; since both genera lack stridulatory apparatus on the tegmina, lack timpani in the first pair of tibia and have no second pair of wings. This new genus differs also in venation of the wings which bear few intercalated veins, those concentrated at the apex.
