Metrichia vulgaris Santos, Takiya & Nessimian 2016

Metrichia vulgaris Santos, Takiya & Nessimian 2016: 45 (Type locality: Brazil, Rio de Janeiro, Itatiaia, Rio Palmital, 22°25’34”S, 44°32’52”W, el. 637 m; DZRJ; ♂); Holzenthal & Calor 2017: 245 (catalog); Santos et al. 2022: 518 (distribution).

Material examined. BRAZIL: Tocantins: Palmas, Parque Estadual do Lajeado, Igarapé do Saltim (#05-TO), 10°03’33.40”S, 48°13’49.30”W, el. 581 m a.s.l., 05–10.vi.2016, A. M. Pes, G. A. Gusmão, J. O. Silva, S. Couceiro, P. Benevides legs., Malaise trap. 1 male ( INPA) .

Distribution. BRAZIL:Atlantic Forest biome (Rio de Janeiro State), Caatinga biome (Ceará State), and Cerrado biome (Goiás and Tocantins [new record] States) ( Fig. 1 ).

Remarks. Differently from most Metrichia species in Brazil with restricted distribution, M. vulgaris has wide distribution, occurring in three biomes and states in Northeast, Central-West, and South Regions ( Santos et al. 2016). Recently, the known range of this species was extended into the Atlantic Forest in the Serra dos Órgãos National Park, a mountain region located in the central portion of Rio de Janeiro State ( Santos et al. 2022). Here, the distribution range of M. vulgaris is extended in the Cerrado to the State of Tocantins, representing the first records for northern Brazil.
