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.

Amphilophus citrinellus (Günther, 1864)

Common name: Midas Cichlid

Synonyms and Other Names: Cichlasoma citrinellum, C. granadense, Heros citrinellus, red devil cichlid, mojarra rayada

Taxonomy: available through www.itis.govITIS logo

Identification: Amphilophus citrinellus is a member of the Midas cichlid species assemblage (Amphilophus spp.), a group of closely related, morphologically similar species thought to comprise a recent adapative radiation (Barluenga and Meyer 2010). Distinguishing characteristics were provided by Loiselle (1980) and Page and Burr (1991). Color photographs appeared in Loiselle (1980), Konings (1989) and Conkel (1993). Although morphologically very similar to Cichlasoma labiatum, the species is considered distinct (Barlow and Munsey 1976; Villa 1976).

Size: 24 cm.

Native Range: Tropical America. Atlantic Slope drainages in Central America from Great Lakes and crater lakes of Nicaragua to Río Coto in southeastern Costa Rica (Bussing 1987). Distribution maps given in Bussing (1987) and in Conkel (1993).

Ecology: Generally found in lakes and estuaries over a variety of substrate types; uncommon to rare in rivers and streams. Usually associated with some sort of structure or cover (e.g., rocky outcrops, logs). Primarily omnivorous, opportunistically consuming algae, insect larvae, benthic invertebrates, and fishes (Barlow 1976). Midas cichlids are substrate spawners, with reproduction generally occurring during the rainy season with breeding pairs defending a small territory around some form of cover (Noakes and Barlow 1973; Barlow 1976). Parental care is provided through protection of eggs and schooling fry from predators and through 'contacting' behavior, where fry will consume dermal mucus of the parents as part of their diet (Noakes and Barlow 1973; Barlow 1976)

Means of Introduction: Introductions into Florida were via aquarium or fish farm releases. In other states, introductions most likely represent aquarium releases.

Status: Established in Florida, Hawaii, and Puerto Rico. Failed in Massachusetts and Minnesota.

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 exhibits two basic color morphs, gray and orange. Most Florida fish are the orange morph (Anderson et al. 1984). A small specimen taken in Hillsborough County, Florida, in 1976 was reported as C. labiatum (Courtenay and Stauffer 1990), but was later tentatively re-identified as A. citrinellus (Smith-Vaniz, personal communication; UF 92199).

The Midas cichlid species assemblage is thought to be an example of sympatric speciation and adaptive radiation. Multiple new forms and species have recently been described from within the crater lakes of Nicaragua (McKaye et al. 2002; Stauffer et al. 2008; Barluenga and Meyer 2010).

Midas cichlid, along with red devil cichlid (A. labiatus) were introduced to, and are established in, Queensland, Australia in 1992 (Lintermans 2004).

Voucher specimens: Florida (CAS 76581; UF 31651, 77515, 91875, 92165), Hawaii (UF 119744).
