Distribution map of Pontella labuanensis by geographical zones
SE Indian (Sunda Strait, S Java )

Type locality: off Labuan (west Java)
N: 2
(162) F: 3,1-2,9; M: 2,6-2,5; {F: 2,90-3,10; M: 2,50-2,60}
Rem.: inshore, estuarine, superficial water of coastal waters of Labuan.
This species belongs to "labuanensis"- Group, Mulyadi, 1997 (See above in Table I). For Mulyadi (2002, p.104) P. labuanensis is distinguishable from other species of Pontella, not belonging to the three groups (alata, fera, andersoni from Fleminger, 1986) by the following combination of characteristics. In the female: urosomal somite 1 does not bear any process, including a genital operculum, except for several sensilla on the dorso-lateral surface; the caudal rami are slightly asymmetrical (the right ramus slightly longer); the terminal segment of the P5 is virtually naked and that of the left P5 is slightly longer and more strongly curved than that of the right P5. In the male: the rostrum has large, double convex lenses; the right P5 has a proximally forked process on exopodite 1 instead of a slender thumb.
P. labuanensis is more similar to the P. alata Group (Ohtsuka & al., 1987).
