Pontella tridactyla  Shen & Lee, 1963   (F,M)
Shen & Lee, 1963 (p.581, figs.F,M [Juv.]); Mulyadi, 2000 (p.194, figs.M, Rem.); 2002 (p.115, figs.M, Rem.);
Species Pontella tridactyla - Plate 1 of morphological figuresissued from : C.-j. Shen & F.-s. Lee in Acta zool. Sin., 1963, 15 (4). [p.582, Figs.26-29].
Female (from N Luichow Peninsula): 26, urosome (dorsal); 27, P5.
Nota: P5 biramous, left leg longer than the right one in both the exopod and endopod.

Male: 28, habitus (dorsal); 29, P5.

Species Pontella tridactyla - Plate 2 of morphological figuresissued from : Mulyadi in Treubia, 2002, 32; [p.116, Fig.42].
Male (from off Labuan, W Java): a, habitus (dorsal); b, forehead (lateral); c, right P5; d, left P5.
Mulyadi (2002, p.117) underlines that Shen & Lee (1963) described and figured this species too briefly, and their female appears to be a copepodid stage of the male by the structure of a 3-segmented urosome and not a yet developed P5.
The present male differ from Shen & Lee’s figures by 1- the presence of 1 short spine on proximal corner of chela near the thumb ; 2- the 4 unequal lamella and 1 long seta on third length of chela of right P5 ; 3- the presence 3 unequal spine-like processes and 1 flagelliform process on exopodal segment 2 of left P5.

Rem.: Mulyadi (2000, p.195) points to the figures 26 and 28 in Shen & Lee (1963) appear to be a copepodid stage.
This species belongs to "P. alata"-Group (See in P. alata in Mulyadi, 2003, Table I)
