Eupomatus humilis .— Hernández-Alcántara et al. 2008: 48 (mentioned only).

Material examined. Four specimens.

Oaxaca: UMAR-Poly 770, 4 spec. ( Salina Cruz , angler pier, main dock, sta. 4, 1 m, May 26, 2011, coll. SGM et al.).

Habitat. Subtidal, 1–10 m (Bastida-Zavala 2008). Found on an angler pier in Salina Cruz , Oaxaca. Also on mangrove, rock and spiny oysters ( Ostrea iridescens Hanley , O. columbiensis Hanley and Spondylus calcifer [now S. limbatus ]) and cobbles on sand (Bastida-Zavala 2008). Occasionally part of fouling fauna.

Distribution. Tropical Eastern Pacific. Baja California to Panamá (Bastida-Zavala & ten Hove 2003).

Remarks. Hydroides humilis is a tiny and rare species; it probably has gone unseen or has been confused with juveniles of other species as H. brachyacantha , H. inermis or H. deleoni , whose opercula are somewhat similar to those of H. humilis . However, the former species have bayonet collar chaetae with two main teeth only, while H. humilis has collar chaetae with two teeth and a proximal rasp (Bastida-Zavala & ten Hove 2003, Fig. 15h). The specific morphological and chaetal characters should be revised in juveniles of Hydroides spp. to evaluate if the specific status of H. humilis is supported or if the nominal taxon represents a semaphoront (juvenile stage) of some, or several, Hydroides species.

Hydroides humilis View in CoL was found on mangrove, rocks and oysters. Two specimens revised by Bastida-Zavala & ten Hove (2003: 92), presumably from Panamá or Costa Rica, were found together with Spirobranchus minutus View in CoL and Ficopomatus miamiensis ( Treadwell 1934) View in CoL ; the last is a Caribbean species that was recorded as exotic in Mazatlán, Sinaloa and the Pacific of Panamá (Bastida-Zavala 2008).
