This genus is distributed from Northwestern Mexico to El Salvador in Central America, being Mexico the most diverse area with eight known species. Through morphological specimen comparisons among them and against the type material of previously described species, fifteen taxa were found to be new to science. The new taxa described here are P. merianae sp. nov., P. humboldti sp. nov., P. darwini sp. nov., P. cooki sp. nov., P. wallacei sp. nov., P. batesi sp. nov., P. mulleri sp. nov., P. linnaei sp. nov., P. lamarcki sp. nov., P. songi sp. nov., P. fontanai sp. nov., P. buzzettii sp. nov., P. hubbelli sp. nov., P. ottei sp. nov. and P. cantralli sp. nov. These species were collected in Mexico from the states of Sinaloa, Durango, Nayarit, Jalisco, Colima and Michoac\u00e1n. The fifteen new species are characterized by unique morphological features from external and internal male genitalia, being the cerci and the dorsal and ventral valves of the endophallus unique and highly informative.\n\u00a0<\/jats:p>","DOI":"10.11646\/zootaxa.5760.1.1","type":"journal-article","created":{"date-parts":[[2026,2,19]],"date-time":"2026-02-19T22:55:53Z","timestamp":1771541753000},"page":"1-56","source":"Crossref","is-referenced-by-count":0,"title":["Studies in Mexican Grasshoppers: Fifteen new species of Proctolabus Saussure, 1859 (Orthoptera: Acrididae: Proctolabinae)"],"prefix":"10.11646","volume":"5760","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0566-1372","authenticated-orcid":false,"given":"RICARDO","family":"MARI\u00d1O-P\u00c9REZ","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4079-498X","authenticated-orcid":false,"given":"SALOM\u00d3N","family":"SANABRIA-URB\u00c1N","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"TED","family":"COHN","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"4913","published-online":{"date-parts":[[2026,2,20]]},"container-title":["Zootaxa"],"link":[{"URL":"https:\/\/mapress.com\/zt\/article\/download\/zootaxa.5760.1.1\/58372","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/mapress.com\/zt\/article\/download\/zootaxa.5760.1.1\/58372","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,2,19]],"date-time":"2026-02-19T22:55:54Z","timestamp":1771541754000},"score":14.096752,"resource":{"primary":{"URL":"https:\/\/mapress.com\/zt\/article\/view\/zootaxa.5760.1.1"}},"issued":{"date-parts":[[2026,2,20]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2026,2,20]]}},"URL":"https:\/\/doi.org\/10.11646\/zootaxa.5760.1.1","ISSN":["1175-5334","1175-5326"],"issn-type":[{"value":"1175-5334","type":"electronic"},{"value":"1175-5326","type":"print"}],"published":{"date-parts":[[2026,2,20]]}}],"items-per-page":5,"query":{"start-index":0,"search-terms":null}}}
