Comparative diagnostic notes. This species closely resembles P. apiculatus (see notes under P. apiculatus ). Similarily, P danieli can be separated from other species by the mesal margin of anterior hamulus notched (mesal margin and apex entire [ P. suasus ], mesal margin of anterior hamulus broadly emarginate on distal half [ P. pacificus and P. indicatrix ]); from P. luisi and P. enriquei by the anterior hamule lacking any kind of tooth or hook on mesal margin (anterior hamule with tooth or hook on mesal margin), and from the remaining species by the anterior hamulus with mesal margin notched and apex entire and rounded (anterior hamulus with mesal margin entire, with the apex cleft forming two subequal branches).

Flight season. June, July, August, and September.

Distribution. Colima, Guerrero, Morelos, Oaxaca, San Luis Potosí ( Fig. 144 ). Only in Mexico.

Natural history. The type locality is a river with a rocky bottom with some sections of sand, shallow and in some places the surrounding vegetation is a gallery forest ( González-Soriano & Novelo-Gutiérrez 1990). According to the records, this species has an altitudinal distribution in Mexico from 33 to 1100masl.
