Espèce Bestiolina similis - Planche 1 de figures morphologiquesissued from : J.G. Greenwood in Proc. R. Soc. Qd, 1976, 87. [p.21, Fig.7]. As Bestiola similis.
Female (from Moreton Bay, E Australia): a, head (lateral); f, P5; g, P1; h, P2; i, endopod of P3; j, endopod of P4.
Male: b, head (lateral); c, posterior metasomal border with P5 in situ and urosome (lateral left side); d, P5; e, terminal region of P5.
Nota: Tis species differs from B. inermis in absence of spine-rows on posterior exopodal segments 1 and 2 of P2 to P4; absence of spinules on 5th thoracic segment,; smaller size and having longer rostral filaments. .


Espèce Bestiolina similis - Planche 2 de figures morphologiquesIssued from : R.B.S. Sewell in Spolia Zeylanica, 1914, 9. [Pl.XVII, Figs.3-5]. As Acrocalanus similis.
Female (from Gulf of Mannar): 3, P3; 4, P4.

Male: 5, P5.


Espèce Bestiolina similis - Planche 3 de figures morphologiquesissued from : S.Y. Moon, W. Lee & H.Y. Soh in Proc. Biol. Soc. Washington, 2010, 123 (1). [p.44, Table 1].
Presence and number of spinules on the anterior surface of the exopods and endopods of swimming legs 2 - 4 from (Sewell, 1914).
These characteristics were taken from Ali & al. (2007).


Espèce Bestiolina similis - Planche 4 de figures morphologiquesIssued from : S. Wellershaus in Veröff. Inst. Meeresforsch. Bremerh., 1969, 11 (2). [p.252, Figs.10-20]. As Acrocalanus similis.
Female (from Cochin Backwater, S. India): 10, habitus (lateral; spot on 5th thoracic segment indicates red pigmentation); 11, forehead (lateral); 13, last thoracic segments and urosome (lateral right side); 15, left P4 and P5 (anterior); 16, A1; 19, Mxp; 20, Md.

Male: 12, forehead (anterior and lateral); 14, 3th to 5th thoracic segments and urosome (lateral right side); 17, A1; 18, urosome (dorsal; somewhat crushed).
Scale : single line = 0.1 mm ; double line = 0.05 mm.

Nota female:
- Ratio thorax : abdomen = 3.3-3.5 (for 7 animals).
- A1 reaches the caudal rami (or is even longer); segments 1-2 to 7 without spinules.
- P5 rudimentary.

Nota male: Ratio thorax : abdomen = 2.5-2.6;
- Head of many males bears a transparent swelling above A2.
- A1 symmetrical.

Remarks: Some animals bear a red patch in thoracic segment 5.
