R. Robles, J. Cuesta & F. Mantelatto, 4 Dec 2001 (ULLZ 10195); ovigerous female (4.8 mm), mature male (2.0 mm), ex left branchial chamber of immature U. dawsoni (5.0 mm CL), Bahia de Los Angeles, Baja California Norte, coll. F. Mantelatto, J. Cuesta & R. Robles, 6 Dec 2001 (ULLZ 10197).
Nicaragua: mature female (6.0 mm; incomplete, sampled for molecular analysis), mature male (2.3 mm) (USNM 1437636 ex ULLZ 10194), ex right branchial chamber of male Upogebia spinigera (6.0 mm CL) (ULLZ 10194), Santa Julia, between Potosi and El Rosario, coll. J. A. Cuesta, R. Robles & J. T. Rodriguez, 19 Nov 2002.
Distribution. Gulf of California from San Felipe, Baja California Norte to Laz Paz, Baja Californa Sur; Tortugas Bay, west coast of Baja California Sur and Todos Santos Bay, Ensenada, Baja California Sur, Mexico; Nicaragua (herein).
Hosts. Upogebia dawsoni Williams, 1986 (type host), U. spinigera (Smith, 1871), U. macginitieorum Williams, 1986, Pomatogebia rugosa (Lockington, 1878).
Remarks. Although often cited as being published in 1989, the original description of this species was in an issue marked as “dépot légal 1er trimestre 1990.” This species appears to be widely distributed throughout the Gulf of California, as well as on the west coast of Baja California. Its absence from the eastern coast of the Gulf of California may be an artifact of fewer hosts being collected in that region, either due to undersampling or less suitable habitats.
The Nicaraguan specimen reported on here resembles P. bruscai in all details of the female except that none of the bases of the pereopods have swollen dorsal knobs (e.g., Salazar-Vallejo & Leija-Tristán 1990: fig 2F; Campos & de Campos 1998: fig. 1L–M). The male likewise shows all the characters of P. bruscai although the pleotelson has fused rather than articulated posterolateral lobes as described and illustrated by Salazar-Vallejo & Leija-Tristán (1990: fig. 3 A, C). However, the fusion of posterolateral lobes of the pleotelson in males is known to be variable in this species (see Campos & de Campos 1998).
Identification of these specimens as P. bruscai greatly extends the known range of the species southward from Mexico. The host, U. spinigera, was previously known to bear Orthione mesoamericana Markham, 2004, in Costa Rica and Colombia.
