Species Pontella latifurca - Plate 1 of morphological figures

issued from: Q.-c Chen & S.-z. Zhang in Studia Marina Sinica, 1965, 7. [Pl.46, 1-8].
Female (from G. of Pohai, Yellow Sea): 1, habitus (dorsal); 2, forehead (lateral); 3, urosome (lateral left side); 4, P5 (posterior).
Nota: Rostrum rather small.
- Head with lateral hooks, distinct from 1st thoracic segment, 4th and 5th distinct.
- Postero-lateral angles of last thoracic segment, triangular, its tip acutely pointed, asymmetrical (left cone longer than the right.
- Urosome 2-segmented.
Genital segment, globular, its dorsal side rather swollen.
- Anal segment, short.
- Furcal rami slightly asymmetrical, right ramus much broader.
- A1 24-segmented, extending beyond posterior edge of 3rd thoracic segment, lower margin of 11th segment with a small process.
- Endopod of A2 longer than exopod.

Male: 5, habitus (dorsal); 6, forehead (lateral); 7, right A1; 8, P5 (posterior).
Nota: Rostrum more well-developed than the female.
- Postero-lateral angles of last thoracic segment short and small, right cone longer than the left.
- Urosome 5-segmented, 4th segment much shorter than anal segment.
- Furcal rami symmetrical, 3 times as long as wide.
- Right A1 17-segmented, 10th to 13th swollen, geniculate between 15th and 16th, upper edge of 16th with a finger-like process.
- Distal segment of left P5 very short, its inner side with a hirsute lamelliform process, its outer side with 2 strong spines.

Species Pontella latifurca - Plate 2 of morphological figures

Issued from : Mulyadi in The Raffles Bull. Zool., 2000, 48 (2). [p.191, Fig.11].
Female (from off Surabaya, E Java): a, forehead (lateral); b, 5th metasomal somite and urosome (lateral right side); c, idem (dorsal); d, P1; e, P5.
Nota: A1 24-segmented. P5 asymmetrical, without spinules or proeminences on inner and outer margins. Urosomite 1 without any processes.
The difference between Chen & Zhang's (1965) descriptions and the present female is the asymmetrical urosomal somite 1, right margin more swollen than left and armed with 1 process posteriorly.

Female (from SE Korea): A-B, habitus (dorsal and lateral, respectively); C, rostrum (ventral); D, genital compound somite (ventral); E, P5.

Species Pontella latifurca - Plate 4 of morphological figures
