Key to troglomorphic species of Phryninae :

1. Dorsal margin of pedipalp patella with one spine between the two longest spines ( Phrynus )........................... 2

- Dorsal margin of pedipalp patella with two spines between the two longest spines ( Paraphrynus )...................... 3

2. Ocular tubercle reduced, with black pigmentation; chelicera with three teeth on external margin of retrolateral surface (Pinar del Rio, Cuba).............................................................................. Phrynus noeli

- Nearly obsolete ocular tubercle is the same color as the carapace (pale brown); chelicera with one or two teeth on external mar- gin of retrolateral surface (Chiapas, Mexico).............................................. Phrynus perrii sp. nov.

3. Median eyes reduced or absent, but at least lateral eyes present.................................................4

- All eyes entirely missing and lacking ocular tubercle (Yucatán, Mexico).......................... Paraphrynus reddelli

4. Median eyes reduced but present; ocular tubercle nearly obsolete................................................ 5

- Median eyes and ocular tubercle absent (San Luis Potosí, Mexico)............................... Paraphrynus velmae

5. Pedipalp tarsus lacking such a dorso-lateral spine............................................................6

- Pedipalp tarsus with a small dorso-lateral spine (Quintana Roo and Yucatán, Mexico).............. Paraphrynus chacmool

6. Pedipalp Fv1 spine slightly curved or only hook shaped at the apex.............................................. 7

- Pedipalp Fv1 spine straight (Tamaulipas, Mexico)............................................ Paraphrynus baeops

7. Pedipalp Fv1 spine slightly curved full length; anterior edge of carapace strongly bilobed; basal segment of chelicera with one tooth on external margin of retrolateral surface (Tabasco, Mexico)............................... Paraphrynus chiztun

- Pedipalp Fv1 spine curved only of apex (hook shaped); anterior edge of carapace moderately bilobed; basal segment of chelic- era with two teeth on external margin of retrolateral surface, the distal tooth slightly smaller and somewhat blunt (Oaxaca, Mexico)............................................................................. Paraphrynus grubbsi
