Material examined. Six specimens.

Baja California Sur: UANL 7857, 4 spec. (Puerto Escondido, sta. 1: 25°48’51.8”N, 111°18’41.2”W, April 2, 2011, coll. JAL & ARB); UANL 7858, 2 spec. (same, sta. 2: 25°48’53.1”N, 111°18’40.5”W, April 2, 2011, coll. JAL & ARB).

Habitat. Intertidal to subtidal (18 m, Moore 1923). Fine gray sand and rock ( Moore 1923); also from anthropogenic substrates in marinas (from Puerto Escondido , Baja California Sur and Mazatlán , Sinaloa). Fouling species.

Distribution. California to Gulf of California (only in marinas).

Remarks. Moore (1923) described this species in Parasabella and Perkins (1984) transferred it to Demonax ; however, all species in Demonax were synonymized with Parasabella ( Tovar-Hernández & Harris 2010) . This species is a new record for the Gulf of California, it is possibly an exotic species introduced by yachts from California.
