The additional records confirm the continued presenceof this species within its recorded range.Pontonia margarita Smith, 1869Material examined.- Guaymas (ca. 27°56’N, 111°5’W), 4specimens, date unknown, intertidal (coll. L.T. Findley) (EMU-8830). Mazatlan harbour (23°10’41”N, 106°25’29”W), 2 specimens,23/Mar/1983, 7 m (coll. Gustavo Klein Barreda) (EMU-8855).

There are three previousrecords of this species in the Southern Gulf of California: two inBahía Mazatlán (EMU-876; EMU-1097) and one in La Paz (EMU-875) (Hendrickx, 1994).Pontonia simplex Holthuis, 1951Material examined.- Isla Puercos, Barra de Navidad(19°11’20”N, 104°40’34”W), 1 specimen, 8/Sep/1983, intertidal(coll.

The materialfrom Cabo San Miguel was collected simultaneously with thespecimens reported by Hendrickx & Hermoso-Salazar (2005). Inwestern Mexico, A. utriensis also is known only from Isla Isabel(Kim & Abele, 1988), Puerto Escondido (Wicksten, 1983), and theIslas Tres Marías (Hendrickx & Hermoso-Salazar, 2005, previousrecords in Mexico as A. cristulipes).Alpheus umbo Kim & Abele, 1988Material examined.- Guaymas (27°56’N, 111°5’W), 1 specimen,3/Feb/1986, intertidal (EMU-8858).

The specimens fromVol. 21 No. 1 • 2011
30 Hendrickx, M. E. and Wicksten, M.

Because the specimen was not in a very good stateof conservation and due to unresolved taxonomic difficulties, theidentification of this material is tentative.Automate rugosa Coutière, 1900Material examined.- Off Teacapan, SIPCO III, St. A1(22°24’12”N, 105°54’24”W), 2 specimens, 15/Jan/1982, 40 m (EMU-8845).
