Key for identification of the scolopendromorph centipedes of Tunisia

1(2) with 4 ocelli on each side of cephalic plate (Family Scolopendridae ) ...............3

2(1) Head without ocelli. Ultimate legs with saw teeth on tibia and tarsus 1 (Family Cryptopidae ) ..................................................................................................9

3(4) Legs without tarsal spurs, pretarsus of ultimate leg longer than tarsus 2, spiracles very small................................................................. Cormocephalus gervaisianus

4(3) Most legs with tarsal spurs, pretarsus of ultimate leg markedly shorter than tarsus .............................................................................................................. 5

5(6) First spiracle (of leg-bearing segment 3) oval (Fig. 21), the rest round............... ...................................................................................... Otostigmus spinicaudus

6(5) Spiracles triangular ( Fig. 4 ), more or less parallel to body axis .........................7

7(8) Leg 1 with two tarsal spurs ( Fig. 3 ); coxopleural process generally long, with at least six spines sited laterally as well as distally ( Fig. 5 ); prefemur of ultimate leg with two rows of spines ventrolaterally and two ventromedially ( Fig. 7 ) .......... ......................................................................................................... S. canidens

8(7) Leg 1 with one tarsal spur (Fig. 10); coxopleural process short, with at most five distal spines, none laterally (Fig. 11); prefemur of ultimate leg with, at most, three rows of three spines ventrally (Fig. 13); femur and sometimes tibia in males flattened with ridged lateral and median edges ...................... S. morsitans

9(10) Tergite 1 with anterior transverse suture from which run two diverging sutures to the posterior border of the tergite ( Fig. 26 ) ............................... C. trisulcatus

10(9) Tergite 1 with anterior transverse suture only (Fig. 28)...................... C. punicus
