Mesokalliapseudes soniadawnae Bamber, 1993

Kalliapseudes (Mesokalliapseudes) soniadawnae Bamber, 1993: 122 , Figs. 1–4. Drumm, 2003: 2, 11. Guţu, 2006: 141. Kalliapseudes soniadawnae Bamber, 1993: 128 , 129, 130.

Mesokalliapseudes soniadawnae . Guţu, 2006: 142, 151.

Type material. Holotype female ( NMW.Z.1991.099.1), 1 paratype male ( NMW.Z.1991.099.2).

Material examined. None available for study. Diagnosis prepared according to Bamber (1993).

Diagnosis (adult). Rostrum rounded. Anterolateral apophyses on pereonites 2–6. Pleotelson broader than long. Inner flagellum of antennule with 3 articles. Third peduncle article of antenna not spinulate. Mandibular palp terminus with a long seta. Fixed finger of cheliped less than one half the length of dactylus.

Type locality. Caribbean Sea , Trinidad, 10°40'N, 61°35'W, depth 10 m (Fig. 1, number 36; Fig. 80 ) .

Geographic distribution. Known from the type locality only.

Remarks. Attempts to borrow type material from the National Museum of Wales were unsuccessful. Based on Bamber’s (1993) description this species can be distinguished from the other congeners by the following characteristics: 1) a short stout pectinate spiniform seta on the ventrodistal corner of the pereopod 1 basis, and 2) no spinulate process on the second peduncle article of the antenna.

Mesokalliapseudes thalasispeleus Gu ţ u, 2006

Mesokalliapseudes thalasispeleus Guţu, 2006: 142–151 : Figs. 209–231.

Type material. Holotype female with oostegites no. 250.299, 1 allotype male no. 250.300, MHN Grigore Antipa.

Material examined. None available for study. Diagnosis prepared from that by Guţu (2006).

Diagnosis (adult). Rostrum rounded. Pereonites lacking anterolateral apophyses. Pleotelson as long as broad. Inner flagellum of antennule with three articles. Third peduncle article of antenna not spinulate. Mandibular palp terminally with short spiniform seta. Fixed finger of cheliped less than one half the length of dactylus. Female chela with less than 10 short spiniform setae on dactylus cutting edge.

Type locality. NW Atlantic, Exuma Cay, Bahamas, approximate coordinates: 23°32'N, 75°50'W (exact coordinates unknown) (Fig. 1, number 37; Fig. 80 ) .

Geographic distribution. Known from the type locality only.

Remarks. Mesokalliapseudes thalasispeleus is the second species of Mesokalliapseudes known from the Bahamas, the other one being M. bahamensis Sieg, 1982 . It is distinguished from M. bahamensis and the members of the genus by two major characters: 1) the shape of the pleotelson (as long as broad; all other species are broader than long), and 2) the short spiniform seta on the mandibular palp terminus. Mesokalliapseudes thalasispeleus appears to be unique in having longer than normal simple setae on the anterior and posterior corners of the pereonites (approximately as long as the associated pereonite).
