Diagnosis.--Key characters: Ommatidial size coarse (Fig. 39b); prosternal process slightly expanded apically (Fig. 18); mesal antennal spines present (Figs. 8b, 9b); pronotum with impunctate regions and without large, confluent punctures or rugose sculpturing; femoral carinae absent; procoxal cavities closed laterally (Fig. 24); mesal profemoral apices spinose (as in Figs. 8d, 9d); lateral profemoral apices rounded (Fig. 26c); lateral mesofemoral apices spinose (Fig. 25a); remaining femoral apices dentiform to rounded (as in Fig. 25b, 26c, d); femora linear (Fig. 37d); elytra not metallic and covered with dense golden and silver pubescence; elytral apices without spines. Length: 12-16 mm.
Distribution and Diversity.--Southeastern Brazil. Monotypic.
Discussion.--Neomallocera has the dense silver and golden pubescence characteristic of the Mallocera and allies clade (Fig. 59). Neomallocera differs from Pseudomallocera in lacking femoral carinae. Neomallocera differs from Mallocera in having procoxal cavities closed laterally (examined Mallocera species had procoxae open laterally) and usually having a narrower facies. Neomallocera differs from Appula in having the elytral apices without spines.
