“…The phylogeny of the ant genus Aphaenogaster in the Iberian Peninsula has been recently revised (Lorite et al 2017). Six species present in the Iberian Peninsula (A. iberica Emery, A. senilis Mayr, A. gibbosa, A. subterranea (Latreille), A. dulciniae Emery and A. cardenai) and one Mediterranean species not present (A. spinosa Emery) were included in that analysis.…”

Phylogeny of the ant genus Aphaenogaster (Hymenoptera: Formicidae) in the Iberian Peninsula, with the description of a new species

A phylogenetic tree of the Iberian Aphaenogaster species - except for A. splendida (Roger) - and a key to the worker caste of all Iberian Aphaenogaster species are proposed. The position of A. striativentris Forel and A. cardenai Espadaler is discussed, stating the possibility that this second species may belong to a new, undescribed genus. Aphaenogaster ulibeli n. sp. is described from the Iberian Peninsula. Its closest relatives are A. gibbosa (Latreille) and A. striativentris. Its habitat seems to be restricted to caducifolia forests in the Western Central Massif.

“…They were found in HargM-2 (tract located between sites 18-414), HargM-80 (located between sites 18-414 and 118-493), HargM-PCR-281 (located between sites 60-164) and HargM-70 (located between sites 433-450), among others. Several authors have recently highlighted the importance of gene conversion processes in satellite DNA evolution (Khost et al, 2017;Lorite et al, 2017), supporting the theoretical models that suggest that the unequal crossing-over and gene conversion processes are the most important and widespread mechanisms involved in the evolutionary dynamics of satellite DNAs (Talbert & Henikoff, 2010). The high conservation of HargM mono-mers together with the detection of putative gene conversion processes indicates that concerted evolution has been important in the evolution of the satellite DNA in H. argus.…”

Satellite DNAs are the major repetitive DNA components in eukaryotic genomes. Although satellite DNA has long been called "parasite DNA" there is substantial evidence that it could be associated with some functions of chromosome biology. Ladybird beetles (Coccinellidae) are one of the largest and most important groups of beetles. Many ladybirds are of economic interest as biological control agents because they eat some agricultural pests such as aphids and scale insects. However, other species are phytophagous and can damage crops. Despite the ecological importance of the latter group there are no studies on their satellite DNA. A satellite DNA family was isolated and characterized in the ladybird Henosepilachna argus. This satellite DNA is organized in tandem repeats of 658 bp and is A + T rich (67.3%). The recorded high sequence conservation of the monomers together with the detection of putative gene conversion processes indicate concerted evolution. Reverse transcription polymerase chain reaction (RT-PCR) revealed that this satellite DNA is transcribed and in situ hybridization its location in the subtelomeric regions of all chromosomes except the long arm of the X chromosome. The presence of this satellite DNA in other species of the genus Henosepilachna and Epilachna was also tested using PCR. The results indicate that this satellite DNA sequence is so far specifi c to H. argus.

“…In conclusion, a broad revision of the Mediterranean Aphaenogaster, aided by the use of molecular data, is surely required in order to establish a reliable framework of phylogenetic relationships among the species. Actually, only a small number of Mediterranean species have been subjects of molecular studies (BRANSTETTER et al 2016, LORITE et al 2017, GÓMEZ et al 2018, CENTORAME et al 2018. However, morphological elements suggest that A. fi orii stat.…”

Abstract More than 100 years ago, the Italian myrmecologist Carlo Emery described two endemic Sicilian ants: Aphaenogaster sicula Emery, 1908, which he originally considered a subspecies of A. crocea André, 1881, and A. fiorii Emery, 1915 stat. nov., which he believed was a subspecies of A. gibbosa (Latreille, 1798). Males of the two species and the queen of A. fiorii were never described. The scarcity of information contained in the original description led to several misunderstandings by subsequent authors: for example, A. sicula was later elevated to species-rank on the basis of misidentified material of A. fiorii stat. nov. We redescribe the two species, adding the descriptions of their missing castes and designating their lectotypes. We also describe a third related species of the genus: A. trinacriae sp. nov. from Sicily. The ecology and distribution of the three are illustrated. Their relationship with the other congeneric species of the Mediterranean basin is discussed considering the morphology of all three castes, with attention to the often-overlooked males. Despite the fact that A. fiorii and A. sicula were lately believed to be close relatives of A. subterranea (Latreille, 1798), the morphological elements available suggest that they probably belong to a separate, hitherto unrecognized clade from the Maghreb (North-Western Africa), together with A. trinacriae sp. nov.
