Nyctocrepis Motschulsky, 1853: 33. Type species: Nyctocrepis demoulini Motschulsky, 1854: 10 (original designation). Diagnosis: Antennal branches shorter than in other cladodine genera, median lamellae only 2.3–3.5× longer than antennomere itself. Labium with apical palpomere of the right triangle shape. Anterior margin of pronotum rounded (triangularly produced forwards in Cladodes s.s.), submarginal punctures on anterolateral corners of pronotum fused, forming vitreous spots, deeper than lateral punctures, phallus as long as parameres. Species included: Nyctocrepis demoulini Motschulsky, 1854, N. (Fenestratocladodes) malleri (Pic, 1935) comb. nov., N. stellata (Gorham, 1880) comb. nov.. Distribution: Brazil. Comments: Considering the absence of a triangular pronotum in Fenestratocladodes (the synapomorphy of Cladodes s. str.) and a phallus as long as the parameres, the subgenus Fenestratocladodes is here placed in Nyctocrepis.
