Key to the species of Turcolana

1. Uropod styliform, about 2x as long as pleotelson, both rami subequaly long. Pleotelson semicircularly rounded, posterior mar- gin without apical excision. Propodial organs on male pereopods 2–3........................... T. lepturoides sp. nov.

- Uropod not styliform, up to 1.2x as long as pleotelson........................................................ 2

2. Pleotelson apical excision (sinus) 0.06–0.1x as deep as pleotelson length.......................................... 3

- Pleotelson posterior margin rounded, exceptionally with slight emargination or shallower sinus....................... 5

3. Pleotelson antero-lateral margins straight, postero-lateral margins strongly converging. Apical sinus as deep as broad. Uropod exopodite slender, more than 0.5x as long as endopodite. Propodial organs on male pereopods 2–3............. T. adaliae

- Pleotelson antero-lateral margins convex, postero-lateral margins not strongly converging. Apical sinus less deep than broad. Uropod exopodite broad, less than 0.5x as long as endopodite. No propodial organs................................ 4

4. Uropod sympodite broad at base, medial margin not convex, medial angle not protruding beyond endopodite medial angle............................................................................................ T. pamphyliae

- Uropod sympodite narrow at base, medial margin convex, medial angle protruding beyond endopodite medial angle..................................................................................................... T. cariae

5. Pleotelson posterior margin almost straight. Uropod endopodite about 0.6x as long as sympodite, exopodite about 0.6x as long as endopodite................................................................................. T. rodhica

- Pleotelson posterior margin rounded or with slight emargination or shallow sinus. Uropod endopodite more than 0.8x as long

as sympodite, rami both of about same length.............................................................. 6 6. Pereonal coxae 2–7 clearly extending beyond posterior margins of respective pereonites............................. 7

- Pereonal coxae 2–3 not extending beyond posterior margins of respective pereonites............................... 8

7. Uropod length up to 16% of BL, sympodite short (compact), apically more than 2x as wide as basally, endopodite about 2x as wide as exopodite. Propodial organs on male pereopods................................................ T. steinitzi

- Uropod length about 18% of BL, sympodite long, apically less than 2x as wide as basally, endopodite up to 1.8x as wide as exopodite, tapering. No propodial organs........................................................... T. smyrnae

8. Uropod length 25% of BL, sympodite 2x as long as wide, endopodite 3.6x as long as wide and 1.3x as wide as exopodite. Pleotelson shape variable. No propodial organs......................................................... T. detecta

- Uropod length 20–23% of BL, sympodite up to 1.8x as long as wide, endopodite up to 2.7x as long as wide and more than 1.6x as wide as exopodite. Pleotelson rounded. Propodial organs on male pereopods 2–3........................... T. reichi
