Uhlias limbatus Stimpson, 1871

( Figs. 6B–C )

Uhlias limbatus Stimpson 1871: 118 [type-locality: St. Thomas; type in USNM]; Rathbun 1897: 38; 1937: 150, pl. 36, figs. 3–5; Abele & Kim 1986: 37; Lira et al. 2005: 95–97, fig. 1; Ng et al. 2008: 94; Poupin 2018: 183, fig. 197.

Distribution. Western Atlantic: USA (Florida, Key West), Cuba, Jamaica, Haiti, St. Thomas, Barbados, Tortuga, Colombia, Venezuela, and Guyana ( Lira et al. 2005; Poupin 2018; present study).

Material examined. Barbados, Coconut Court , Christ Church, nearshore rubble, 13°04’31.59”N, 59°36’13.78”W, 1 ♀ CW: 6.2 mm ( BLSZ 193 ) .

Remarks. This is the first record of Uhlias limbatus from Barbados. This specimen was collected in nearshore rubble habitat at low tide, under rubble rock, in a tidal pool on the south coast of Barbados. The frontal margin, orbitals, protogastric, mesogastric, and hepatic regions of the carapace of this specimen (BLSZ 193) are covered with crustose coralline algae ( Figs. 6D, E ). Rathbun (1921: 67) reported two species from the family Leucosiidae that were collected in Barbados by the Barbados-Antigua Expedition in 1918. One male specimen of Ebalia stimpsonii A. Milne-Edwards, 1880 was collected at depths of 63–135 m (35–75 fathoms) (USNM 77147) and specimens of Iliacantha subglobosa Stimpson, 1871 , (three juvenile females and one male, USNM 1460420, 1460419, 110228, 1460421) were collected at depths of 90–360 m (50–200 fathoms). This study did not find any specimens of Ebalia stimpsonii or Iliacantha subglobosa .
