São Paulo (SඉൺൾඍΗ1936b);Cantareira (Bඈඋඈඐංൾർ2002). Type material examined. Sඒඇඍඒඉൾඌ: 2 spec. , glued, ‘ SAÕ PAULO | BRAS. MRÁZ LGT. | MUS.PRAGENSE [w, p, cb, bf] || Coptocycla | arcuata Sw. [hw by F. Spaeth] | Spaeth det. [w, p, cb]’ ( NMPC ); 1 spec. , glued, ‘ SAÕ PAULO | BRAS. MRÁZ LGT. | MUS.PRAGENSE [w, p, cb, bf] || Coptocycla | arcuata [hw by F. Spaeth] | Spaeth det. [w, cb, p]’ ( NMPC ); 14 spec. , glued, ‘ SAÕ PAULO | BRAS. MRÁZ LGT. | MUS. PRAGENSE [w, p, cb, bf]’ ( NMPC ). Each specimen was provided with an additional label: ‘ SYNTYPUS | Coptocycla | ruficornis | Spaeth, 1936 | L. Sekerka des. 2020 [r, p, cb, bf]’. Distribution. Brazil ( São Paulo ). Remarks. SඉൺൾඍΗ (1936b) described C. ruficornis based on material collected by J. Mráz as he wrote (translated from German): ‘So far known only from the state of Sao Paulo , where mainly J. Mráz collected numerous specimens ( Holotype and many paratypes in the National Museum in Prague , more paratypes in my collection).’ Based on the NMPC material I assume that Spaeth borrowed the series and returned it identified as C. arcuata (Swederus, 1787) as there is no specimen identified as C. ruficornis , and that he retained part of the series for his collection. Later on, when he revised the genus Coptocycla Chevrolat, 1836 he realized that the series collected by J. Mráz actually belonged to a new species, described it and included the NMPC specimens in the type series by indication. However, he failed to label any specimen of the series as ‘typus’ thus they all must be considered syntypes . The three specimens in his collection have ‘cotypus’ on their labels (Lech Borowiec, pers. comm. 2020). In NMPC there are two more specimens of C. ruficornis collected by J. Mráz, however they came from a private collection of A. Jedlička, who received them directly from J. Mráz and thus, they certainly were not examined by F. Spaeth and cannot be part of the type series.
