Espèce Paraheterorhabdus (Paraheterorhabdus) longispinus - Planche 4 de figures morphologiques

issued from : C.C. Davis in Univ. Wash. Publs Biol., 1949, n. ser. 14. [Pl.11, Figs.128-137]. As Heterorhabdus longispinus.
Male: 128, right P5 (posterior face); 129, endopod of right P5; 130, exopod of right P5 (lateral view from right side); 131, Mx2; 132, right Md (mandibular palp); 133, right Md (masticatory blade); 134, left Md (masticatory blade); 135, P2; 136, P3; 137, exopod of P1.

Nota : Head and 1 st thoracic segment separated. The head constitutes more than half the length of the metasome. Front with a small papilla, on the ventral side of which is the rostrum. Lateral angles of the end of prosome are rounded. Urosome slightly greater than ½ the length of the metasome, and all of the five segments more or less equal in length except the anal, which is only 1/3 to ¼ the length of the others. Left caudal ramus longer than the right, and the 2 nd from the inner seta heavier than the others and longer than the entire body of the animal. A1 reach just about to the end of the caudal rami ; right A1 25-segmented ; left one geniculate of 21 segments. 1 st endopodal segment of A2 with a dense row of fine hairs on the distal portion of the outer margin. The masticatory portion of left M dis not the same as that of the right. Mxp with a short thin seta on the middle of the inner border of the 1 st basal segment ; the proximal end of the outer border of the 2 nd segment bears a swelling that is larger than ordinary. P1 with a long spine on the outer distal corner of the 1 st exopodal segment. Protrusion on the inner border of the 2 nd exopodal segment of the right P5 is pointed, and relatively large ; the 2 nd segment is greatly enlarged on the inner border ; the spine on the outer distal corner of the 1st segment of the 1st exopod is very long.

Paraheterorhabdus (Paraheterorhabdus) longispinus female: 1 - Left caudal ramus distinctly longer than right and completely fused with anal segment (Fig.46-c)
2 - Dorsally, posterolateral corners of prosome angular (Fig.46-c).
3 - Laterally, 2nd urosomal somite (Fig.46-b) without a swelling along ventral margin.
4- Laterally, posterior slope of genital prominence concave (Fig.46-e).

Paraheterorhabdus (Paraheterorhabdus) longispinus female:
1 - Left caudal ramus distinctly longer than right and completely fused with anal segment.
2 - Basis of right P5 with conical inner lobe.
3 - P5 with relatively slender exopods; medial projection of 2nd exopodal segment of right P5 without a lobe on distal side.
4 - Medial projection of 2nd exopodal segment of right P5 toothlike (Fig.47-e, f).
5 - In 3rd exopodal segment of left P5 (Fig.47-d), inner spine about on the same level as outer spine.
