Giupponia P\u00e9rez-Gonz\u00e1lez &amp; Kury, 2002 is one such case: it was erected for the blind troglobite G. chagasi from limestone caves in Serra do Ramalho, southwestern Bahia, Brazil, and has remained monotypic for more than two decades. Here, we describe two additional troglobitic species from caves in the same karst area, thereby expanding the genus and providing an updated diagnosis and an identification key for males. The new species share core troglomorphic traits with G. chagasi (complete eye loss and depigmentation) and a distinctive suite of external and genital characters that support their placement in Giupponia, including a theta-type dorsal scutum with wide ridged grooves, a prominent preocular mound with paired spiniform armature, an enlarged ocularial apophysis, and a characteristic penial configuration with a pyriform ventral plate, a parabolic distal cleft and a robust stylus bearing a dorsal projection, with the glans lacking dorsal\/ventral processes. We further discuss the morphological evidence bearing on the suprageneric placement of Giupponia within Gonyleptoidea Sundevall, 1833, highlighting affinities with lineages traditionally treated in Pachylinae and possible relationships with Ampycidae Kury, 2003 or Tricommatinae Roewer, 1912. These findings underscore the hidden diversity of the Serra do Ramalho subterranean fauna and the need for integrative phylogenetic analyses to resolve the evolutionary origin of extreme troglomorphisms in Brazilian gonyleptids.<\/jats:p>","DOI":"10.3390\/ani16111609","type":"journal-article","created":{"date-parts":[[2026,5,25]],"date-time":"2026-05-25T14:10:22Z","timestamp":1779718222000},"page":"1609","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Two New Troglobitic Species of Giupponia P\u00e9rez-Gonz\u00e1lez &amp; Kury, 2002 (Opiliones: Gonyleptoidea) from Caves of Bahia, Northeastern Brazil"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5268-7946","authenticated-orcid":false,"given":"Jonas E.","family":"Gall\u00e3o","sequence":"first","affiliation":[{"name":"Laborat\u00f3rio de Estudos Subterr\u00e2neos, Departamento de Ecologia e Biologia Evolutiva, Universidade Federal de S\u00e3o Carlos, S\u00e3o Carlos 13565-905, S\u00e3o Paulo, Brazil"},{"name":"Instituto Brasileiro de Estudos Subterr\u00e2neos, S\u00e3o Carlos 13565-545, S\u00e3o Paulo, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9515-4832","authenticated-orcid":false,"given":"Maria E.","family":"Bichuette","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio de Estudos Subterr\u00e2neos, Departamento de Ecologia e Biologia Evolutiva, Universidade Federal de S\u00e3o Carlos, S\u00e3o Carlos 13565-905, S\u00e3o Paulo, Brazil"},{"name":"Instituto Brasileiro de Estudos Subterr\u00e2neos, S\u00e3o Carlos 13565-545, S\u00e3o Paulo, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8334-6204","authenticated-orcid":false,"given":"Adriano B.","family":"Kury","sequence":"additional","affiliation":[{"name":"Departamento de Invertebrados, Museu Nacional\/UFRJ, Rio de Janeiro 20940-040, Rio de Janeiro, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4560-5391","authenticated-orcid":false,"given":"Marcos R.","family":"Hara","sequence":"additional","affiliation":[{"name":"Escola de Artes, Ci\u00eancias e Humanidades, Universidade de S\u00e3o Paulo (EACH USP), S\u00e3o Paulo 03828-000, S\u00e3o Paulo, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,5,25]]},"reference":[{"key":"ref_1","unstructured":"Kury, A.K., Mendes, A.C., Cardoso, L., Kury, M.S., Granado, A.d.A., Giribet, G., Cruz-L\u00f3pez, J.A., Longhorn, S.J., Medrano, M., and de Oliveira, A.B.R.
