On behalf of a Italian biologist who contacted me (Luca Giaccaglia), I ask experts from researchgate to give their opinion on this Apseudes species from a marine area of Sicily (Italy). Luca says it is similar to A. grossimanus, but not the same. As I'm no expert myself on tanaids from the Mediterranean I ask you. You can answer on researchgate or send Luca ([email protected]) your opinion/advice.
Although his pictures are not that good, an expert may see something that can help him.
Ton:
As the specimens are damaged and not complete it could be still described as Apseudes sp. It does not match with species: Apseudes grossimanus (Norman) Norman & Stebbing, 1886. Kindly see link (Fig. 5d):

Hi Tom and Luca,
looking at this specimen, with its long pleon, highly acuminate pleonal epimera, pereonite-6 shape, and pereopod-1 propodus with four inferior spines suggests Tuberapseudes echinatus Sars. I can't be any more definite than this.
Cheers,
Graham
Graham:
Trusting your expertise it seems that the documented specimens match species Tuberpseudes (= Apseudes) echinatus (Sars, 1882). Would you kindly post a photograph of well preserved specimen of this species? Thanks a lot.

Hi Syed,
sorry I don't have a photo of echinatus and it's a long time since I had a specimen. I've relied on Sars' original drawing and those of Băcescu & Guţu 1971 (Travaux du Museum d'Histoire naturelle "Grigore Antipa" 11: 59-70.
I should have added that the view of the rostrum confirms it is not grossimanus (trifid) and is consistent with echinatus.
Cheers,
Graham
Thanks Syed and Graham for your helpfull contribution. I have forwarded your answers to Luca.
two other pictures of this species, just for fun. Send to me by Luca.
