On the identificaton of Cynotliapia afra On the identificaton of Cynotliapia afra
By Juan Miguel Artigas Azas

A new paper by Patrick Tawil about Cynotilapia has been just published in Cybium. It turns out that the fish we have been widely knowing as Cynotilapia afra has been wrongly identified, its real identification being Cynotilapia zebroides, previously considered a junior synonym of C. afra. The paper also offers the scientific description for C. sp 'mbamba', which we will now know as C. aurifrons, a proper specific name for it. One debatable aspect of the paper includes the proposed resurrection of the genus Microchromis, which has been considered a junior synonym of Cynotilapia.

Invisible pair bonds detected by molecular analyses Invisible pair bonds detected by molecular analyses
By Juan Miguel Artigas Azas

A new paper by Tetsumi Takahashi, Haruki Ochi, Masanori Kohda and Michio Hori has been published in the electronic magazine Biological Letters, showing that in the Lake Tanganyika school forming cichlid Microdontochromis rotundiventralis, whose schools are comprised by both mouth-brooding and non mouth-brooding individuals, it is more likely that the biological father holds larger fry passed by the female, which shows that the pair bond is maintained by this species at least until that point in the school, without apparent physical proximity of the pair.

By Juan Miguel Artigas Azas

A new species of Cichlasoma, Cichlasoma zarskei by Felipe Ottoni (Federal University of Rio de Janeiro) has been published today in the electronic version of Vertebrate Zoology. The new species, closely related to Kullander's Cichlasoma orientale, was previously known as Cichlasoma cf. orientale 'Maranhão' and differs from C. orientale among other aspects; by having a longer snout, wider head and shorter lower jaw. It is restricted to the Maranhão River basin in northern Brazil.

By Juan Miguel Artigas Azas

A new species of Apistogramma, Apistogramma playayacu has been described and published today in the electronic version of Vertebrate Zoology. The new species inhabits in the Ecuadorian Napo River system and probably belongs to the Apistogramma macmasteri species complex. It is the 71th species of Apistogramma described.

New paper published on the role of egg-spots in haplochromine cichlids New paper published on the role of egg-spots in haplochromine cichlids
By Juan Miguel Artigas Azas

A new paper by Bernd Egger., Yuri Klaefiger., Anya Theis & Walter Salzburger has been published in the digital magazine Plos One. The paper deals with the role of egg-spots on haplochromine male cichlids anal fins as an attractor for females. Males of about 1500 mouth-brooding species utilize these conspicuous egg-dummies during courtship apparently to attract females and to maximize fertilization success. The purpose of the experiment is to test the hypothesis that the evolution of haplochromine egg-spots was triggered by a pre-existing bias for eggs or egg-like coloration. The results of the tests indeed revealed that females are attracted by egg-spots, and those colors preferred are yellow, orange or red.

New behavior paper on Neolamprologus pulcher published New behavior paper on Neolamprologus pulcher published
By Juan Miguel Artigas Azas

One new behavior study by Bruintjes, Rick, D. Bonfils, D. Heg M. Taborsky on the highly researched Neolamprologus pulcher has been published in PLoS ONE. The study shows that in the colony cooperative breeding species, subordinate males (those that are not the dominant male in a colony) can gain paternity mating with individuals in the colony. Such paternity makes them more eager to defend the colony against potential egg predators than those males not participating in reproduction.

Two new species of Stigmatochromis from southern Lake Malaŵi have been described by Jay R. Stauffer Jra, Rachel M. Cleaver-Yodera, and Ad Konings, namely Stigmatochromis macrorhynchos and Stigmatochromis melanchros, the paper appearing today in the Proceedings of the Biological Society of Washington.
