The Nonindigenous Occurrences section of the NAS species profiles has a new structure. The section is now dynamically updated from the NAS database to ensure that it contains the most current and accurate information. Occurrences are summarized in Table 1, alphabetically by state, with years of earliest and most recent observations, and the tally and names of drainages where the species was observed. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. References to specimens that were not obtained through sighting reports and personal communications are found through the hyperlink in the Table 1 caption or through the individual specimens linked in the collections tables.

Protemblemaria punctata Cervigón, 1966

Common name: Warthead Blenny

Taxonomy: available through www.itis.govITIS logo

Identification: The species has an elongate body with a rounded blunt head that lacks spines, two bushy branched cirri over each eye, and three dark bars under the jaw (Robertson and Van Tassell 2015).  Orange spots cover the body and are larger anteriorly (Robertson and Van Tassell 2015).  The iris has wedge-shaped markings and a pair of ridges extends from between the eyes to the dorsal fin (Humann and Deloach 2002). Colors may be variable.

Distinguished from other similar appearing native blennies by a dark or clear ocellus on the foredorsal (males) or a dark flag on the upper foredorsal (females), wedge-shaped markings on the iris and, occasionally, a pale bar angled downward and posteriorly from the eye continuing across preoperculum and operculum. Often, though not always, exhibit two fleshy ridges extending from between eyes to foredorsal.

Size: up to 5.1 cm (Robertson and Van Tassell 2015)

Native Range: Along the coast of northeast Venezuela (Williams and Craig 2015).

Nonindigenous Occurrences: One specimen was collected in Tampa Bay, Florida, on the northwest side of a small island just outside of Port Manatee in January 2017 (FSBC 30436).  Additional individuals were seen in 2019 and 2020 on the south end of the Sunshine Skyway Bridge, Manatee County, Florida.  Eight adults were collected in Veracruz, Mexico in November 2019 (Argüelles-Jiménez et al. 2020).  There is a record from Trinidad in February 2016 near Port of Spain.

Ecology: This species lives in empty mollusk shells, on reefs, and in mangroves (Robertson and Van Tassell 2015).  This is the only blenny in the Chaenopsid family known to inhabit mangroves (Humann and Deloach 2002).  They are found in up to 20 m depth and feed on benthic crustaceans, gastropods, bivalves, and zooplankton (Robertson and Van Tassell 2015).

Means of Introduction:  Unknown, but possibly by hitch-hiking on towed oil/gas platforms or ships.

Status: Possibly established.

Impact of Introduction: The impacts of this species are currently unknown, as no studies have been done to determine how it has affected ecosystems in the invaded range. The absence of data does not equate to lack of effects. It does, however, mean that research is required to evaluate effects before conclusions can be made.
