Canarana brachialis

Canarana brachialis (Guérin-Méneville, 1855) (Fig. 61) Hemilophus brachialis Guérin-Méneville, 1855: 600. Spathoptera brachialis; Thomson, 1878: 16. Adesmus brachialis; Aurivillius, 1923: 589. Hilarolea brachialis; Soukup, 1942: 311. Canarana brachialis; Martins & Galileo, 1992b: 443. Hilarolea croceicollis Gahan, 1889: 393. Remarks. Hemilophus brachialis was described based on a single specimen, sex not specified, from Ecuador (Napo). According to Tavakilian & Chevillotte (2023) and Monné (2024b) the holotype is a female. These two authors also informed that the holotype is from Ecuador (Napo: Quixos). However, there is no information in the original description indicating where the specimen was collected. Actually, Cajetano Osculati, collector of the holotype specimen, was in several places in Ecuador during his stay in that country, but also stayed in Brazil (e.g. Tabatinga, São Paulo de Olivança, Fonte Boa, Ega (currently Tefé), Manaus, Santarém, etc.) (Osculati 1854; Papavero 1973). Therefore, it is not possible to be sure even if the specimen was really collected in Ecuador. Perhaps an eventual information on the labels of the holotype may elucidate this. We did not find any information in Osculati (1854) that could indicate where the holotype of this species was collected. Later, Gahan (1889) described Hilarolea croceicollis based on a probable female from Bolivia. Martins & Galileo (1992b) synonymized H. croceicollis with Canarana brachialis. Currently, it is known from Ecuador (Napo), Peru, Brazil (Mato Grosso), and Bolivia (Chapare, Cochabamba, and Santa Cruz) (Monné 2024b; Tavakilian & Chevillotte 2023). The specimen from Mato Grosso listed in Martins & Galileo (2014) is actually from Mato Grosso do Sul. Therefore, we are excluding this species from the fauna of the Brazilian state of Mato Grosso until a specimen is formally collected there. We are provisionally maintaining Ecuador as a country where this species occurs. Apparently, C. tuberculicollis Guérin-Méneville, 1855 is just a chromatic variation of C. brachialis. The color of the femora and the shade of the color of the prothorax is variable in C. brachialis. Material examined. BRAZIL, Mato Grosso do Sul: Campo Grande, 1 female (MNRJ-ENT-47643), 04.X.1978, W.W. Koller leg. (MNRJ); Rio Verde [see comment on “Rio Verde” in remarks of Oncideres malleri Fragoso, 1970], 1 female (MZSP 61261), XII.1965, A. Maller leg. (MZSP).
