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.

Common name: wolf cichlid

Synonyms and Other Names: Heros dovii Günther 1864, Cichlasoma dovii (Günther 1864), Nandopsis dovii (Günther 1864); Dow's cichlid, guapote, guapote blanco, lagunero.

Taxonomy: available through www.itis.gov

Identification: In general, cichlids (Cichlidae) are superficially similar to sunfishes and black basses (Lepomis and Micropterus; family Centrarchidae). Cichlids can be distinguished from centrarchids by a single nostril opening on each side of the head (vs. two in centrarchids) and the presence of a discontinuous or two-part lateral line (vs. a continuous in centrarchids).

An identification key, description, and color photograph are provided by Bussing (1987)

Size: to 50 cm SL (Kullander 2003)

Native Range: The Wolf Cichlid is native to Central America including the Atlantic slope, from the Aguan River (Honduras) to the Moín River (Costa Rica); and the Pacific slope, from the Yeguare River (Honduras) to the Bebedero River (Costa Rica) (Glaser et al. 1996; Kullander 2003; Froese and Pauly, 2012).

Ecology: The Wolf Cichlid inhabits lakes but also thrives in various lower and middle river valleys. It prefers tropical temperatures of 21–37 °C (Froese and Pauly, 2012). This species is an avid cavern digger.  Parachromis dovii, similar to other guapotes, is highly piscivorous, consuming characins, other cichlids, and poecilids, with aquatic invertebrates comprising a smaller portion of the diet, primarily in juveniles (Bussing 1987).  It is considered to have medium fecundity with a minimum population doubling time of 1.4–4.4 years (Froese and Pauly, 2012).

Means of Introduction: Aquarium release.

Status: Established in Loiza Reservoir in eastern Puerto Rico since at least 2009.

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.

Remarks: This species is also introduced in El Salvador (McMahan et al. 2013)
