S. securifrons has the same internal features in the forehead as seen in M. chelipes, but externally its chitinous dorsal margin does not sxell markedly to form a lens-shaped structure. Appendages A1 to Mxp are structurally identical in both species. The external hyaline margin above the flap on endopodite of P1 is thicker in S. securifrons than in M. chelipes. Both species have a spine-like process on basipodite 1 of P2 to P4. The groups of spines on posterior surfaces on exopodal segments 2 and 3 of P2 and P3 are present in both species, but in S. securifrons spines of groups II to IV are more clearly arranged in an arch. Only a few spines (indicated by arrows in Fig.4A) can be seen on the posterior surface on exopodal segment 3 of P4 in S. securifrons. The structure of male P5 is basically the same in thes species, the tight leg of S. securifrons, however, has a very reduced endopodite and exopodite of 2 segments, the second of which with a hyaline flap ("conical retroverted process" in Sewell, 1929, p.202) proximally, as in M. chelipes (Fig.4B); exopodal segment 2 of left leg of S. securifrons is strongly haired distally with bent setae fewer but longer than those of M. chelipes (compare Fig.4C with Fig.4D) | | | Last update : 30/10/2015 | |
