“…Apistogramma females were regularly observed in extremely shallow, warm (up to 35 °C), nearly anoxic, and acid water. Here numbers of large predators were low to zero, and, as usually only one Apistogramma species was observed in such physiologically extreme environments, it is possible that even interspecific competition is lacking, creating conditions that constitute safe territory for brooding dwarf cichlid females (RöMeR et al, 2012). Nevertheless, in addition to continuous predation, interspecific competition may be a key factor in developing mouth-brooding behaviour against a given environmental background.…”

“…All specimens were initially preserved in 95 % ethanol to permit the taking of DNA samples, with most individuals being transferred into 75 % ethanol later. DNA samples were taken and preserved as described in and stored as detailed in RöMeR et al (2012). The description is based on observations on all type specimens.…”

“…In recent decades numerous new species of the genus Apistogramma Regan, 1913 have been discovered in Brazil, Venezuela, and especially Peru. Some of these forms have been scientifically studied and the vast majority of them described for the first time only in recent years (BRitzke et al, 2015;kullandeR, 1980, 1986kulland-eR & FeRReiRa, 2005; Mesa & lasso 2011a-b; Ready & kullandeR, 2008;RöMeR, 1994RöMeR, , 1997RöMeR & HaHn, 2008, 2013RöMeR et al, 2003RöMeR et al, , 2004aRöMeR et al, -b, 2006bRöMeR et al, -d, 2011RöMeR et al, , 2012RöMeR et al, , 2013scHindleR & staeck, 2013;staeck, 1991staeck, , staeck & scHindleR, 2008VaRella & BRitzke, 2016;VaRella & saBaj PéRez, 2014), bringing the total number of valid species to significantly over 90 and making Apistogramma the largest genus among the Neotropical cichlids. However, there are still several forms awaiting formal description.…”

Description of a new maternal larvophilic mouth-brooding cichlid species, Apistogramma megastoma sp. n. (Teleostei: Perciformes: Geophaginae), from Loreto, Peru

Apistogramma megastoma sp. n. is described based on a total of 18 specimens from small forest streams in the Departamento Loreto, Peru, tributaries of the Río Jutai in the border area between Peru and Brazil south and west of the city of Leticia (Colombia) (near 04°12′ S / 70°06′ W). Apistogramma megastoma sp. n., which may be confused only with A. barlowi, is distinguished from all other Apistogramma species by the combination of: noticeably disproportionately large head; exceptionally massive jaws, lyrate densely vertically banded caudal fin, extended dorsal-fin membranes in males; in aggressive females sooty head pattern and up to 8 series of small black dashes on flanks; small round caudal spot; and, exceptional for Apistogramma, maternal mouth-brooding behaviour. Distinguished from A. barlowi, by differences in colour pattern and by higher number of scale rows on cheeks. Apistogramma megastoma sp. n. inhabits in small fastflowing streams.

Apistogramma payaminonis Kullander, 1986 is redescribed based on the only two type specimens available, and two new, closely-related Apistogramma species are described from Peru. Data from the original description of A. payaminonis are supplemented with information on phenotypic appearance, which is important for differentiating the taxon from several other species discovered in the last few years. Apistogramma feconat sp. n. is described from four specimens from the catchment of the Río Tigre, Loreto; information on its ecology, biology, and current conservation status is summarised. Apistogramma wolli sp. n. is described from six specimens from the catchment of the Napo river, Loreto, close to the Peru-Ecuador border; information on its ecology and biology is sparse. Both newly described species are representatives of the Apistogramma nijsseni complex that live in small forest streams influenced by blackwater. Information on differentiating females of some members of this group of related species is presented. At present no clear information based on voucher specimens is available regarding the possible distribution of the two species in Ecuador. Man-made environmental hazards potentially endangering the aquatic fauna in the western catchment of the Río Marañón and the Rio Amazonas, between their tributaries the Rio Pastaza and the Rio Napo, are discussed.

1. Assessing biodiversity and understanding how it works is a prerequisite for species conservation. The Amazon basin is one of the main biodiversity hotspots where fish are heavily exploited for ornamental purposes.2. The ornamental trade heavily exploits the genusApistogramma, which is one of the most species-rich among Neotropical cichlids with 94 formally described species. This number is certainly underestimated owing to the limitations of conventional taxonomy, which is still too often based solely on morphological criteria and sometimes on few individuals.3. Most species of this genus have a high degree of endemism and are highly prized on the ornamental market, which could put them at risk. A few species are supposed to have extensive distributions, and in particularApistogramma agassizii, present from the Amazon estuary up to the Ucayali and Maranon rivers in Peru.Please note that this is an author-produced PDF of an article accepted for publication following peer review. The definitive publisher-authenticated version is available on the publisher Web site.5. According to the molecular calibrations, these three species would have diverged during the Plio-Pleistocene. Two of them seem to be endemic from small sub-basins, one from the Nanay River and the other from the Apayacu/Ampiyacu systems. A possible scenario that may explain the evolutionary history of these species is proposed.6. The conservation implications of these results on the estimation of the diversity ofA. agassizii, ofApistogrammaspecies in general, and of other Amazonian cichlids are discussed.
