Genus Wandogarida gen. n. Figs 1, 2, 3, 4, 5, 6, 7, 8, 9

Generic diagnosis.

Rostrum narrow and prominently extended. Carapace wider than long. Pereonite 3 with lateral apophyses. Pleonites each with a ventral spur and pointed epimera. Pleotelson with slight distal extension. Antennule inner flagellum biarticulate; peduncle article 1 in males with a vertical row of rough denticles and groove. Antenna 8-articulate, without squama. Mandible without palp; molar with distal setulose setae and spinose cutting edge. Maxillule with uniarticulate palp. Pereopods 2-4 propodus with ventral seta. Uropod exopod 3-articulate.

Etymology.

The name refers to Wando, a port city near the type locality and garida from the Greek γαίδα, meaning “shrimp” (feminine).

Type species.

Wandogarida canalicula sp. n.

Remarks.

Wandogarida gen. n. is classified in the subfamily Sphyrapodinae following Guţu (1980), Larsen (2005) and Bamber and Marshall (2013), with a definition based on the following morphological features: 1) the rostrum is prominently extended anteriorly; 2) the pereonites are all wider than long; 3) the antennule has a short inner flagellum with 1-2 articles; 4) the mandible is without a palp; 5) the maxillule is with or without a palp; and 6) the pereopod 1 and cheliped are with exopod.

The subfamily is now composed of five genera: Ansphyrapus Guţu, 2001, Poligarida Bamber & Marshall, 2013, Sphyrapoides Guţu & Iliffe, 1998 and Sphyrapus Sars, 1882, including the new genus Wandogarida .

Wandogarida resembles Poligarida in the absence of an antennal squama, antennule with a biarticulate inner flagellum, pereonite 3 with anterolateral pointed apophyses and outer flagellum of the male antennule with fringes of aesthetascs. However, Wandogarida can be differentiated from Poligarida by the following: in both sexes, the number of antenna articles is different (8 vs. 7); the maxillule has a uniarticulate palp (vs. absence); the carpus and propodus of pereopods 2-3 and propodus of the pereopod 4 have ventral spiniform setae (vs. absence); in females, the mandible molar has several setulose distal setae and sharp, spinose distal margin (vs. with distal setae and simple distal edge); in males, sexual dimorphism exists in the antennule article 1 with a vertical row of rough denticles and concave distolateral margin, in reduced and simplified mandibles, maxillule, maxilla and maxilliped endite, in the larger and more robust cheliped and in the shape of ventral margin of the pereopod 1 dactylus, while it exists only in the antennule, cheliped and pereopod 1in Poligarida .
