Origin of dorsal fin slightly posterior to opercular margin; dorsal fin continuous, with only a slight notch between the spinous and soft portions. Caudal fin slightly emarginated; anal fin rounded; pectoral fin pointed and reaching the level of anus, length longer than the distance from tip of snout to posterior edge of preopercle, and 3.0-3.6 (3.5) times in SL. Nostrils small, posterior nostril elongate and at level of pupil, anterior nostril more rounded and located slightly below the level of the posterior one. Preopercle serrate, its lower margin with visible but weak notch and knob. Scales small, ctenoid, not extending dorsally on head above upper margin of orbit nor onto interorbital and internarial space; scales above lateral line (between dorsal-fin origin and lateral line) 6; transverse scale rows between upper edge of opercle and caudal base 37-47 (39); scale rows on cheek 6-7 (7); soft dorsal and anal fins scaled; dorsal scale rows parallel to the longitudinal body axis. Reddish body cast in life (Figure 2), becoming light brown dorsally and pale ventrally in preserved specimens (Figure 1). Body scales with more intense pigmentation on margins, paler in centers. Sides with six pale, thin, vertical lines dorsally. First band on the nape in front of the dorsal fin, fifth under the junction of spiny and soft portion of dorsal fin, and sixth bellow soft dorsal fin. These pale lines are still visible in some preserved specimens but, as observed by Starck (1970) for

, some specimens may lack these lines. Conspicuous spots (blue in life) are present on the cheek and preopercle, 7-10 of these typically present on snout and ventral portion of head, most below ventral margin of orbit and above superior margin of premaxilla. Median fins red, with more dense pigment on the margins, becoming pale brown in preserved specimens. Live individuals with thin blue distal margins on ventral, anal, and soft dorsal fins (Figure 2) that are not apparent in preserved specimens (Figure 1). Pupils black, iris reddish copper.

Between 2-3 cm SL, specimens from shaded mangrove areas have dense melanophore rows on body, 6-8 pale vertical bands, and an oblique, black eye stripe (Figure 3). Distal portions of first dorsal and pelvic fins dark red. Caudal, soft dorsal, posterior elements of anal, and pectoral fins transparent. Two thin blue lines from maxilla to posterior margin of opercle. Short, oblique blue line from posterior orbit to opercular margin (Figure3). Specimens from unshaded rocky areas or tidepools can also exhibit pale yellow pigment dorsally and on the distal portions of the soft dorsal and caudal fins. Newly settled individuals from softbottom adjacent to mangroves lack red fin pigment, instead with melanophores concentrated distally on first dorsal, pelvic and anterior anal fins. Remaining fins transparent. Lateral bands on body, and blue and black lines on head begin development by 15 mm.</paragraph>

Etymology. The specific name honors the pioneer Brazilian naturalist Alexandre Rodrigues Ferreira (1756-1815), whose many years of field work in Brazil during the late 18th Century remain underrecognized due to the confiscation of his and others’ collections at Lisbon’s Museu da Ajuda in 1808 (Oliveira & Daly 2001). Ferreira collected many specimens that were ultimately described as new without any reference to his efforts. The common name Brazilian snapper is proposed for

Habitats of the Brazilian snapper include coral reefs, rocky shores, coastal lagoons with brackish water, mangroves and other shallow habitats with a mixture of soft- and hard-bottom. Recorded depths range from intertidal (early stages only) to at least 54 m (Feitoza et al. 2005 - identified as

<paragraph id="B75F044A0AB34801EE65BD5F2B6891D2" pageNumber="37">Recent discoveries of new species belonging to major coastal fish families in Brazil (referenced in Introduction) suggest a considerable level of isolation between Caribbean and Brazilian populations of coastal fishes, especially those that associate with reefs. Genetic studies also indicate limited gene flow between these two zoogeographic areas, even within groups with a high potential for dispersion such as surgeonfishes (Rocha et al. 2002). Mechanisms of speciation and faunal enrichment in another group of coastal fishes (Scaridae) were recently studied in the Atlantic by Robertson et al (2006), based on mtDNA and nDNA sequences to assess the effects of two major geographic barriers (the>30 million year old Atlantic ocean and the ~11 million year old Amazon -Orinoco outflow). Fluctuations in sea level, climate, and ocean-current dynamics over the past ~10 million years likely produced marked variation in the effectiveness of the Amazon barrier, allowing intermittent dispersal leading to establishment and allopatric speciation. This dynamic Amazon barrier represents a major engine of West Atlantic faunal enrichment that has repeatedly facilitated bi-directional dispersal, allopatric speciation, and remixing of the Caribbean and Brazilian faunas (Moura & Sazima 2003, Rocha 2004, Robertson et al. 2006).</paragraph>

<paragraph id="568BE4F7D273127787C5ED8FB9DFC320" pageNumber="37">Because of this considerable isolation, caution should be used when management decisions are based on populations from different sides of the Amazon-Orinoco barrier. Moreover, several of the recently discovered species are relatively abundant on coastal habitats such as reefs and mangroves, but were frequently misidentified(see Rocha & Rosa 1999, Moura et al. 2001). This amplifies the need for depositing voucher specimens from ecological and fishery studies in major collections, supports the call for collection building in developing countries, and stresses the need for additional analyses of the numerous systematic problems peculiar to tropical coastal ichthyofaunas.</paragraph>
