Oxycoleus laetus Júlio, 1997 View in CoL

( Figs 36–37 View FIGURES 32–37. 32–35 )

Oxycoleus laetus Julio, 1997: 3 View in CoL ; Júlio et al., 2000: 23 (holotype); Martins & Galileo, 2003: 59; Monné, 2005: 427 (cat.); Monné & Monné, 2016: 27 View Cited Treatment (holotype); Monné, 2021: 623 (cat).

Remarks. Júlio (1997) compared O. laetus with O. ruficollis ( Zajciw, 1964) . However, the species appears to be more similar to O. brasiliensis ( Tippmann, 1953) . Comparing the photographs of the holotype male of O. laetus and O. brasiliensis (wrongly described as a female, see Zajciw (1964) and Martins & Galileo (2003)), the most reliable difference appears to be the length of the antennae: longer in males of O. brasiliensis (the antennae extend about a third of their length beyond the body – Tippmann (1953)) than in O. laetus (antennae surpassing elytral apex by the two last antennomeres – Júlio (1997)). Unfortunately, the holotype and paratypes of O. laetus , as well as the holotype of O. brasiliensis were destroyed during the fire in 2018 at the MNRJ.

Júlio (1997) also reported on the elytra (translated): “elytral carina restricted to a short shining area on apical 1/6.” However, the two females examined by us have no elytral carina even on the apical area.

Material examined. BRAZIL, Mato Grosso: Chapada , 2 females, no date and collector indicated ( MZSP) .
