''Gilvossius'' is a genus of thalassinidean crustacean erected in 1992 from former members of the genus ''Callianassa (genus), Callianassa''. It is distinguished from ''Callianassa'' by the rounded, rather than squarish telson, and by the absence of the first two pleopods in males.

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Callianassa Marchali
''Callianassa'' is a genus of mud shrimps, in the family Callianassidae. Three of the species in this genus ('' C. candida'', '' C. tyrrhena'' and '' C. whitei'') have been split off into a new genus, '' Pestarella'', while others such as '' Callianassa filholi'' have been moved to '' Biffarius''. The genus is named after the Nereid of the Greco-Roman mythology. Species Six species are currently recognised in the genus ''Callianassa'': *'' Callianassa australis'' Kensley, 1974 *'' Callianassa diaphora'' Le Loeuff & Intes, 1974 *'' Callianassa marchali'' Le Loeuff & Intes, 1974 *'' Callianassa ogurai'' Henmi, Itani, Osawa & Komai, 2022 *'' Callianassa subterranea'' (Montagu, 1808) *'' Callianassa timiris'' (Sakai, Türkay, Beuck & Freiwald, 2015) ;Incertae sedis *''Callianassa? anoploura'' Sakai, 2002 *''Callianassa? chakratongae'' Sakai, 2002 *''Callianassa? exilimaxilla'' Sakai, 2005 *''Callianassa? gruneri'' Sakai, 1999 *''Callianassa? nigroculata'' Sakai, 2002 *''Callianas ...

Gilvossius Tyrrhenus
''Gilvossius tyrrhenus'' (formerly ''Pestarella tyrrhena'') is a species of mud shrimp which grows to a length of . It lives in burrows in shallow sandy parts of the sea-bed in the Mediterranean Sea and northern Atlantic Ocean. It is the most common thalassinidean in the Mediterranean, and has been used as bait by fishermen for at least 200 years. Description ''G. tyrrhenus'' is a small crustacean, up to long, with a soft exoskeleton apart from two large, unequal claws. It is whitish or greenish-grey, with pink or blue spots. Because of its burrowing lifestyle, ''G. tyrrhenus'' has small eyes on short stalks, and its maxillipeds can form an operculum; the telson is very short, and the rostrum is almost entirely absent. Larval development is rapid and involves few stages. Eggs hatch into a zoeal stage, which is followed by a second zoea and then a megalopa stage before adulthood. This rapid development allows the larvae to settle down into their adult habitat of relatively undi ...
