description: Preliminary key to the species of Salmoneus and Deioneus recorded from the East Atlantic and the Mediterranean Sea
(*problematic characters that need to be confirmed on additional specimens)
1. Posterolateral articulated flap on pleonite 6 absent; neither of first pereiopods with very large tooth on pollex; lateral plate on coxa of third maxilliped rounded......................................................................... 2
- Posterolateral articulated flap on pleonite 6 present; larger first pereiopod with very large tooth on pollex; lateral plate on coxa of third maxilliped acutely produced....................................................... Deioneus sandizelli
[West Africa (Cape Verde Islands and São Tomé), associated with the callianassid ghost-shrimps Neocallichirus pachydactylus and Corallianassa intesi]
2. Rostral carina extending beyond carapace middle [major chela plump, conspicuously inflated, possibly with unarmed fingers*]................................................................................ Salmoneus jarli [West Africa (Nigeria), questionable record from the eastern Mediterranean Sea (Israel)]
- Rostral carina, if present, not extending beyond carapace middle................................................ 3
3. Posterior margin of telson with deep median notch, lateral spiniform setae distinctly shorter than mesial spiniform setae; body colour in life: bright orange............................... Salmoneus kekovae [eastern Mediterranean Sea (Turkey)]
- Posterior margin of telson straight or with shallow median sinus, lateral spiniform setae distinctly longer than mesial spiniform setae; body colour in life: translucent white (sometimes with yellowish tinge or with yellow or orange ovaries visible by translucence)......................................................................................... 4
4. Telson more than 3.5 times as long as wide proximally [stylocerite either falling short or distinctly overreaching distal margin of second article of antennular peduncle*]..................... Salmoneus sketi [Adriatic Sea (Croatia), in marine caves]
- Telson less than 2.7 times as long as wide proximally; stylocerite not reaching distal margin of second article of antennular peduncle............................................................................................ 5
5. Major cheliped carpus without ventromesial process...................................... Salmoneus erasimorum [Adriatic Sea (Croatia) and Atlantic coast of France (Brittany), associated with the callianassid ghost-shrimp Gilvossius tyrrhenus]
- Major cheliped carpus with strong ventromesial process....................................................... 6
6. Major cheliped much larger than minor cheliped; carpus of minor cheliped subcylindrical, unarmed; cutting edges of major chela fingers serrated with 13 or 14 teeth; cutting edges of minor chela fingers serrated with 5 or 6 low teeth..................................................................... Salmoneus saotomensis [West Africa (Gulf of Guinea)]
- Major cheliped only slightly larger than minor cheliped; carpus of minor cheliped cup-shaped, armed with strong ventromesial process (as in major cheliped); cutting edges of major chela fingers armed with 6 or 7 spaced, irregular teeth; cutting edges of minor chela fingers armed with at most 3 broad teeth..................................... Salmoneus caboverdensis [West Africa (Cape Verde Islands), associated with the callianassid ghost-shrimp Neocallichirus pachydactylus]
