Key to species of Neogonodactylus from the eastern Pacific

1. Telson of Bredini-type, with intermediate teeth not set off from submedian intermediate denticles, but set at the same level or posteriorly to the end of the intermediate tooth.......................................... N. zacae ( Manning, 1972)

- Telson of Oerstedii-type, with intermediate marginal teeth distinct and intermediate denticles located anteriorly to the end of the intermediate tooth.................................................................................. 2

2. Accesory intermediate carinae of telson not armed with spinules or tubercles...................................... 3

- Accesory intermediate carinae of telson armed with spinules or tubercles......................................... 4

3. Telson lacking dorsal tubercles on carinae, except for the median occasionally ending in a strong spine................................................................................................ N. pumilus ( Manning, 1970)

- Telson with median and anterior submedian carinae terminated in a spine; dorsal carinae of submedian teeth usually with a median spine.................................................................... N. stanschi ( Schmitt, 1940)

4. Accessory median carinae of telson short, not extending anteriorly for one-fourth of the length of median carina, and fused posteriorly with median carina to form an anchor; a small spinule underside the lobe of the lateral tooth.................................................................................................... N. festae ( Nobili, 1901)

- Accessory median carinae of telson long, as long or almost as long as the median carina, not fused posteriorly; no spinule underside the lobe of the lateral tooth...................................................................... 5

5. Accessory median carinae of telson terminating in a spine, without spinules along its margin, but occasionally 1or 2 tubercles present.............................................................................................. 6

- Accessory median carinae of telson terminating in a spine, with spinules or tubercles along its margin............................................................................... .. Neogonodactylus lalibertadensis ( Schmitt, 1940)

6. Anterolateral angles of rostral plate acute, not sharp or spiniform; accessory median carinae of telson with 1 or 2 marginal tubercles............................................................ N. albicinctus ( Manning & Reaka, 1979)

- Anterolateral angles of rostral plate sharp, spiniform; no marginal tubercles or spinules on the accessory median carinae of telson................................................................................................. 7

7. Anterolateral angles of rostral plate sharp, but not spiniform; ocular scales quadrate or rectangular; telson frequently with four antero-dorsal spots, knob with 3 or 4 spinezs.................. Neogonodactylus costaricensis ( Manning & Reaka, 1979)

- Anterolateral angles of rostral plate spiniform; ocular scales rounded; telson without dorsal spots, knob with 2 small spines.............................................................. Neogonodactylus bahiahondensis ( Schmitt, 1940)
