Catorthontus collaris Waterhouse, 1880: 487 View in CoL .

Remarks. This species was described based on a single specimen. According to Waterhouse (1880), the holotype “ Hab. Sarayacu,” a place that, based on the title of the work (New Cerambycidae from Ecuador), is in Ecuador. However, according to Santos-Silva & Devesa (2021) on Criodion tuberculatum Gahan, 1892 : “ Gahan (1892) reported: “Hab. Peru, Sarayacu; and (?) Cayenne.” According to Martins and Monné (2005) (translated): “The original localities, “ Peru, Sarayacu; and (?) Cayenne” ( Gahan, 1892: 26), encloses a misunderstanding because Sarayacu is located in Ecuador, and the hitherto dubious occurrence in Cayenne was recently confirmed (Tavakilian in Hequet, 1996).” However, this information about Sarayacu is wrong. Sarayacu is placed in the region of Loreto, province of Ucayali, in Peru. It is true that there is a place in Ecuador named Sarayacu [also transcribed Sarayaku] in the province of Pastaza. But there is no reason to suppose that the information on the original description was a mistake. Therefore, one of the type localities is restored to Peru.” According to Vane-Wright (1991), on the collector of the holotype (Clarence Buckley): “Clarence Buckley collected in Ecuador, Bolivia and possibly Colombia during the late 1860s and 1870s … For his first Ecuador collection, which was made during the period July 1868 to June 1869, Buckley was absent from England for 14 months. Setting out from Guayaquil on 5 th July, he had to cross the Andes to reach his objective, the Amazon slopes. Despite “almost constant rain” he “contrived to bring home with him 5000 butterflies, most of them as fresh and beautiful as if they had been reared from caterpillars at home”. The furthest point reached was St. Rosas, on the Rio Napo. Other localities included Riobamba, Baños, St. Ines, Canelos, Sarayacu, Curaray, Rio Rotuno and Jorge.” Even so, according to Horn & Kahle (1935): “Buckley, Clarence (—ca. 1881), Sammelte mehrfach in Peru, Bolivien u. (zum Teil zusammen mit Gloyne) in Ecuador (1869/81) [... collected several times in Peru, Bolivia and (partly together with Gloyne) in Ecuador (1869/81)]. Ausbeuten fast ganz an E. W. Janson (London); ein geringer Teil Lepidopt. direkt an W. C. Hewitson u. H. Bruce.” Therefore, it is not possible to be sure if the holotype is from Sarayacu in Peru or Sarayaku in Ecuador, unless there is a label on the holotype indicating Ecuador. There is a specimen from Peru illustrated on Bezark (2025), but there is no formal published record. Currently, it is known from Ecuador and Brazil (Amazonas).
