Espèce Acartia (Acanthacartia) fossae - Planche 8 de figures morphologiquesIssued from : R. Gurney in Trans. zool. Soc. London, 1927, 22. [p.157, Fig.22].
Female (Suez Canal): A, habitus (dorsal); B, abdomen (dorsal); C, P5.

Male: D, abdomen (dorsal); E, abdomen (lateral); F, P5.

Nota female:
- Body slender.
- last thoracic somite rounnded, with a row of 4 to 5 small teeth (as in A. clausi).
- Proportion of thorax to abdomen (included furca) 84 : 24.
- Abdomen 3-segmented.
- Genital somite (= double-somite) longer than somites 2 and 3 combined, and as wide as long. This double-somite has a few small lateral hairs, but there are no dorsal spines on this or succeeding somites.
Rostral filaments present, very slender.
- A1 reaches to end of 2nd abdominal somite.
- P5P5 basal segment short and broad; length 16, breadth 12. Terminal spine rather stout and curved, smooth.

Nota male:
- Abdomen and thorax 58 : 110.
- last thoracic somite rounded and with teeth as in female.
- Abdomen 5-segmented
- 1st abdominal somite with lateral hairs.
- Abdominal somites 2, 3, 4 with posterior row of very minute denticles, dorsally.
- Furcal rami [= caudal rami] short and broad, with inner hairs.
- A1 reaches nearly to end of thorax.
- Right P5: exopod with a process on posterior side bearing a slender seta; 2nd exopodal segment produced into a large inner lobe. 2nd exopodal segment of left leg with a stout terminal spine and a curved anterior seta.

For Gurney, this species very closely resembles A. bifilosa, from which it is separated only by some minute details.
