According to Aurivillius (1921): “Long. Corporis 20–25 mm ”; and, “Columbien Collectio VAN ROON.—Amazonas, Reichsmuseum in Stockholm.” The first affirmation implies that Aurivillius had, at least, two specimens when de- scribed the species. Although he had mentioned a male, he did not designate a specimen as holotype. Accordingly, there are syntypes. Even so, the species has been mentioned as having a holotype specimen (e.g. Toledo & Hovore 2005). The information about localities provided by Aurivillius (1921) suggests that one specimen is from Colombia and the other from “Amazonas”. The latter place could be the Amazonas River ( Brazil or Peru), the Brazilian state of Amazonas, Peruvian department of Amazonas, or Colombian region currently corresponding to the department of Amazonas. Currently, the syntypes are deposited in the NHRS and RMNH. According to Hans Huijbregts (RMNH; personal communication): “I have found 3 flavolineatus specimens from Colombia in the van Roon collection. There is only one label “flavolineatus” written by van Roon which was originally on the bottom of the box. There are no labels written by Aurivillius. They could well be syntypes but there is no proof these are really the specimens seen by Aurivillius.” Unfortunately, we could not see the syntype deposited in the NHRS. We prefer to not provide a photograph of the specimen from the former van Roon collection without examining the syntype deposited in the NHR. However, the specimen photographed by Hans Huijbregts agrees perfectly with the specimens from Ecuador illustrated in Bezark (2019).

Dillon (1957) synonymized L. flavolineatus with L. rosaceus Bates, 1869 . Toledo & Hovore (2005) considered L. flavolineatus as distinct from L. rosaceus , and revalidated it as a subspecies of L. araneiformis , stating: “Because material from nearby lower elevation sites in Ecuador exhibits phenotype intermediacy with araneiformis , it seems prudent at present to regard flavolineatus as a subspecies of Lagocheirus araneiformis .” We agree with Toledo & Hovore (2005), especially because we do not know where the type(s) of L. araneiformis is/are deposited, making comparisons impossible. According to Horn & Kahle (1935), concerning the former owner of the type(s) of L. araneiformis : “Brünnich, Morten Thrane (1737–1827), Sammlg, an Zool. Mus. Kopenhagen.” However, the website of the ZMUC (2018) did not list the type(s) as being present in that institution. There are five specimens deposited in the LSUK from former Linnaeus collection ( LSUK 2018). From those specimens, only one has a label, apparently, handwritten by Linnaeus himself ( Fig. 8 ) because the calligraphy agrees very well with that figured in Horn & Kahle (1937) ( Fig. 9 ). Even so, we do not know if the specimen is the holotype or if it was identified by Linnaeus after the original description. The other three specimens were incorporated into the Linnaeus collection by J. E. Smith, because they have a label indicating “W. Roe”. According to Fitton & Harman (2007): “Contributors to Smith’s collection included S. Wilkin, T. Marsham, A. Macleay, W. Roe...” The last specimen has no label, and its origin cannot be tracked.
