Type material. Holotype male from NICARAGUA, Rivas: vic. Rancho Santana, 27.V.2003, E. van den Berghe col. (TAMU, formerly DHCO). Paratypes—MEXICO, Chiapas: MX 190, 5 km S of Ocosingo, 1 male, 1 female, 8. VI.2009, Skillman and Hildebrant col. (FWSC). NICARAGUA, 1 male, same data as holotype except 10-22.VII.2004 (DHCO); 2 females, same data as holotype except 10-20. VI.2004 (MZSP; DHCO). Granada: Nandaime (Reserva Silvestre de Domitila), 1 female, 13-16. VI.2004, A. Audureau col. (AACP); 1 male, 1-5. VI.2005, A. Audureau col. (AACP); 2 males, 1 female, 9-21. VI.2007, A. Audureau col. (AACP); 1 male, 6-13. VI.2010, A. Audureau col. (AACP). Remarks. It is possible that P. sallaei from Costa Rica, sensu Swift et al. (2010) is actually P. audureaui sp. nov. Following the key from Toledo (2005), P. audureaui sp. nov. is included in the alternative of couplet “19” with P. ebenina Linsley, 1935, and P. levicollis Chemsak & Noguera, 1993 (see photographs of the holotypes in Bezark 2019a). It differs from P. ebenina by the head and prothorax color distinctly contrasting with elytral color (with the same color in P. ebenina), and prothorax more elongated (proportionally shorter in P. ebenina). It differs from P. levicollis by the prothorax more elongated (proportionally shorter in P. levicollis), elytral apex truncate and without spiniform projections (narrower and with distinct spiniform projections in P. levicollis). P. audureaui differs from P. megalops Chemsak & Noguera, 1993 (see photographs of the types in Bezark 2019a), but differs by the spine of the antennomere III acute at apex (blunt in P. megalops) and slightly longer than pedicel (longer than twice length of the pedicel in P. megalops), and elytral apex slightly wider and without spiniform projections (narrower, somewhat emarginate and with spiniform projections in P. megalops). It differs from P. cylindricollis Linsley, 1935, and P. brevicornis Linsley, 1934 (see photographs of the holotypes in Bezark 2019a) especially by spine of the antennomere III shorter and with acute apex (distinctly longer than twice length of the pedicel and with blunt apex in P. cylindricollis); from P. subglabra Linsley, 1935 (see photographs of the holotypes in Bezark 2019a), by the elytra without spine at apex (with long spine in P. subglabra); from P. subpicea (White, 1853) (see photograph of the holotype in Bezark 2019a) by the procoxal cavities open behind (closed in P. subpicea), and by the elytra apex without spiniform projection (present in P. subpicea). P. audureaui differs from P. sallaei Bates, 1885 (Fig. 22), with which has been confused, by the spine of the antennomere III with acute apex (blunt in P. sallaei). Etymology. This species is named for our friend and colleague, Alain Audureau, of France, who also works on Neotropical Cerambycidae.
