Primno brevidens Bowman

Primno brevidens Bowman, 1978: 8–10, figs 3d–j, 5–8.

Type material

The holotype and paratypes are in the USNM (Cat. no. 170203 & 4): in spirit.

Remarks

This is one of the medium sized species of Primno reaching lengths of 9 mm. It is distinguished (together with P. evansi) from its congeners by the short teeth on the anterior margin of the carpus of pereopod 5. It is very similar to P. evansi but seems to be restricted to the mid­Pacific. Bowman (1978) also records it from the southeastern part of the Gulf of Guinea, but this material may be referable to P. evansi, if these two species should be maintained as geographically isolated entities. However, I have also seen a female specimen from the Gulf of Guinea ( Galathea stn. 66) which is referable to P. brevidens rather than P. evansi .
