Primno latreillei Stebbing

Primno latreillei Stebbing, 1888: 1445–1447, pl.179A.

Type material

The three syntypes of P. latreillei are in the BMNH (89.5.15.243): on four microscope slides .

Remarks

This is one of the smaller species of Primno, with adults reaching only 6–10mm in length. It is very similar to P. johnsoni, and Vinogradov et al. (1982) regard P. johnsoni as a junior synonym of P. latreillei . Amongst the Australian material examined (Zeidler 1992a, 1998) there was considerable variation in the relative length of the basis of pereopod 7 compared to the remaining articles combined, ranging from slightly longer to about twice as long. This brings the specimens within the morphological range of P. johnsoni, which is probably synonymous with P. latreillei . The morphological variation found in pereopod 7 appears to be ontogenetic.

Primno latreillei seems to have a scattered distribution having been recorded from the Tasman Sea, the North Pacific Ocean (off California), the Red Sea, the eastern Mediterranean Sea and the south­eastern part of the Gulf of Guinea.
