“…Besides Harmonicon cerberus sp. n., these setae are found in specimens of Harmonicon rufescens from Altamira (unpublished data), Harmonicon oiapoqueae (see a picture on the website of Drolshagen 2013) and several undescribed species from Brazil. However, an undescribed Harmonicon from Mato Grosso lacks these setae altogether.…”

A new species of Harmonicon F. O. Pickard-Cambridge, 1896 (Araneae, Dipluridae) is described, from a medium-sized lateritic cave in Parauapebas, Pará, Brazil. The male holotype and only specimen known of H. cerberus sp. n. was found near the entrance of Pequiá cave. This taxon is the fourth species described and the southernmost record for the genus. The new species displays some troglomorphic characteristics, such as reduction and merging of the posterior median and both pairs of lateral eyes and pale yellow to light brown coloration. Both characters are diagnostic when compared to the normal separated eyes and reddish to dark brown of other Harmonicon species. Other diagnostic characteristics are isolated, long, rigid setae distal to the lyra and the shape of the copulatory bulb. This is the second troglomorphic mygalomorph species from Brazil and the first from the Amazonian region.

Information on the genus Harmonicon F.O.P.-Cambridge, 1896, a key to the species and a new diagnosis differing from the one in Maréchal and Marty (1998) are provided. A new species is described: Harmonicon oiapoqueae differing from other species of the genus by the morphology of the posterior sternal sigilla, the more recurved, inverted U–shaped fovea, the amount and arrangement of maxillary cuspules, a single row of teeth on the claws of the palpal tarsus, longer and more slender legs III and IV in females, longer embolus, thinner bulb, and longer, more slender legs in males. The status of the putative junior synonyms of Harmonicon, Pseudohermachura Mello-Leitão, 1927 and Prosharmonicon Mello-Leitão, as well as the two species formerly assigned to Harmonicon, Harmonicon nigridorsi Mello-Leitão, 1924 and Harmonicon riveti Simon, 1903, is discussed.

“…The new genus cannot be placed in the known subfamilies following diagnosis provided by Raven (1985). However, with an amended diagnosis by Drolshagen and Bäckstam (2009) the new genus may be placed in the subfamily Diplurinae in bearing the synapomorphy of a single row of teeth on chelicerae. Within Diplurinae the Orientothele gen. nov. differs from Metriura in bearing a single row of teeth on superior tarsal claws (vs. 2 in Metriura), from Diplura, Trechona, and Harmonicon in lacking prolateral maxillary lyra (vs. absent in Diplura, Trechona, and Harmonicon).…”
