Distribution

Neotropical region.

Remarks

1) As already pointed out by Gorham (1888), M. ornatus (Duponchel) “is one of the most variable species of the Erotylidae , hence descriptions founded upon colour alone are of little value”. Gorham (1888) synonymized five species under M. ornatus (see heading above), mentioning that “species cited as synonymous present absolutely no structural difference and probably several others described by Lacordaire are in the same position”. In fact, we dissected several male indivuals phenotypically close to the species synonymized here, as well specimens showing other colour variations, and their genitalia have exactly the same morphological pattern. Aside from that, the ventral and dorsal morphologies follow the same pattern in all specimens, with no consistent and conspicuous differences among them. Therefore, eighteen synonyms are here included under M. ornatus . 2) We observed, based on colour pattern and structures of male genitalia, that M. ornatus is morphologically similar to M. scitulus Lacordaire ( Fig. 36E ), M. expressus Kuhnt ( Fig. 24C ), M. dorsonotatus Lacordaire ( Fig. 28D ), M. fallax (Guérin-Menéville) ( Fig. 22C ) and M. fasciolatus Lacordaire ( Fig. 29C ). 3) The labels of the lectotype of M. coronatus (Duponchel) ( Fig. 13 A’, new synonym of M. ornatus ) seem to preserve its full story: (i) the disc-shaped label has the name “Campos geraés” (Campos Gerais), which is one of the places that Augustin F.C.P de Saint-Hilaire (who collected that specimen ( Duponchel 1825: 51)) visited during his expedition through Brazil from 1816 to 1822 (see Papavero 1971). The region of Campos Gerais corresponds to a place close to Curitiba, the capital of the state of Paraná in South Brazil ( Pereira & Iegelski 2004), and the specimen may have been collected in 1820, the year in which Saint-Hilaire visited there (see Papavero 1971); (ii) The letter of the label “coronatus” resembles that of Saint-Hilaire who, probably, may have also suggested that name to Duponchel, the latter describing the species as “ Erotylus coronatus ” in 1825; (iii) The letter of the label “ Mycotretus coronatus Duponchel ”closely resembles that of Lacordaire (see Horn et al. 1990b: 507, an example of Lacordaire lettering). Lacordaire, transferred that species from Erotylus to Mycotretus ( Lacordaire 1842: 141) , and it is worth noting that he made a mistake mentioning that the examined M. coronatus would have been collected in “Minas Geraes” (Minas Gerais), a state in Southeast Brazil; (iv) The printed label “Lectotipo” (in Portuguese) follows the pattern used by Moacyr Alvarenga, who visited some European natural history museums in the 1960s. Although Alvarenga may have labeled this specimen, he never published any lectotype designation; (v) The last label was recently added by the senior author and includes the current identification of the species. 4) Lacordaire (1842:137) synonymized Mycotretus pectoralis , a name that appears in the Dejean Catalogue (1836), with M. ornatus . However, the former species was never described and was mentioned in the literature only a few times (e.g., Gemminger & Harold 1876; Gorham 1888), being absent in the two main catalogues containing Neotropical Erotylidae (i.e., Blackwelder 1945; Alvarenga 1994). Furthermore, we did not locate its type in any of the examined collections. Therefore, here we considered the name Mycotretus pectoralis a nomen nudum.
