“…Later, Throckmorton (1975) recognized it as a paraphyletic taxon, and named it the immigrans-Hirtodrosophila ''radiation'' stating that it forms the basis ''out of which, at different times and levels, other groups arose''. Subsequent studies supported the scenario first envisioned by Throckmorton (1975) of an immigranstripunctata clade closely related to other genera in Drosophilidae (DaLage et al 2007; Kwiatowski and Ayala 1999;Robe et al 2005;Robe et al 2010;Tatarenkov et al 2001; van der Linde and Houle 2008), although its phylogenetic affinity to the Hirtodrosophila genus was not so thoroughly recovered (Remsen and O'Grady 2002;Robe et al 2010). Furthermore, the different phylogenetic hypotheses suggested for the immigrans-tripunctata clade usually involve topologically intermingling of many of its groups and subgroups (Hatadani et al 2009;Robe et al 2005Robe et al , 2010Yotoko et al 2003), with most agreement concerning ''brushy'' phylogenies, with deep nodes and/or Electronic supplementary material The online version of this article (doi:10.1007/s10709-010-9453-0) contains supplementary material, which is available to authorized users.…”

Despite previous efforts, the evolutionary history of the immigrans-tripunctata clade remains obscure in part due to its hypothesized origin through a rapid radiation. We performed a supermatrix analysis (3,243 base pairs) coupled with richness patterns, environmental phylogenetic signal and radiation tests in order to address phylogenetic relationships and macro-evolutionary hypotheses within this complex group of species. We propose a well-supported evolutionary scenario for the immigrans-tripunctata clade species, in which the tripunctata "radiation" was monophyletic and subdivided into three main lineages: the first including D. pallidipennis (pallidipennis group) imbedded among members of the tripunctata group; the second clustering the cardini and guarani groups; and the third grouping representatives from the tripunctata, calloptera and guaramunu groups. Therefore, we hypothesize that the tripunctata group encompasses a diphyletic taxon, with one clade including the pallidipennis group and the other showing a close affinity to the calloptera and guaramunu groups. Our results also suggest that niche evolution seems to have played a central role in the evolutionary history of the tripunctata species "radiation" allowing effective dispersion and diversification in the Neotropics, possibly in a southwards direction. Although the data as a whole support the notion that this occurred through rapid and successive speciation events, the radiation hypothesis remains to be further corroborated.

“…Among the 18 analyzed groups from genus Drosophila, only the melanogaster group has these sequences. Nevertheless, hosimary sequences were found in Zaprionus indianus, a species that is distantly related to the melanogaster group (Remsen and O'Grady 2002;Robe et al 2005). The high sequences similarity present (more than 90% at the nucleotide level) suggests a new probable case of horizontal transfer (HT) involving some species from the melanogaster group and Z. indianus.…”

hosimary: a new hAT transposon group involved in horizontal transfer

et al. 2010

A PCR screening approach was used to search for sequences homologous to a previously described hAT transposon found in Drosophila simulans and Drosophila sechellia, named here as hosimary. In this study, 52 Drosophilidae species were analyzed and these sequences seem to be restricted to some species of the melanogaster group and Zaprionus indianus. These species present variable number of copies and most of those appear to be putatively encoding. The high hosimary sequences similarity among different species and the patchy distribution presented by this transposon strongly support the hypothesis that hosimary was horizontally transferred between the melanogaster group species and Z. indianus.

“…Moreover, several authors have pointed out that the tripunctata group is not monophyletic [Kastritsis et al, 1970;Throckmorton, 1975]. Two recent studies covering the molecular systematics of the tripunctata radiation [Yotoko et al, 2003;Robe et al, 2005] reinforced the hypothesis that the tripunctata group and subgroups proposed by Frota-Pessoa [1954] cannot be considered monophyletic groups. Yet both studies showed, in accordance with Throckmorton's ideas, that the tripunctata radiation is a large and speciose monophyletic lineage.…”

The location of rDNA on chromosomes has been found to be highly variable in different groups of insect families of various orders. Yet, in other insect families the rDNA position is relatively constant. This contrast so far has received limited attention. We investigated the rDNA position on mitotic chromosomes in 18 species of Drosophila, 16 of which are from the tripunctata radiation, subgenus Drosophila, through fluorescent in situ hybridization (FISH). All species showed fluorescent signals only on the sex chromosomes. On the X chromosome a single fluorescent mark, but with variable locations, was found. On the Y, we observed variation both in location and in number of fluorescent marks (from 1 to 5). This constancy of chromosome location, in contrast to the great variability found in other groups, is consistent with the work carried out in other species of Drosophila. This suggests that the presence of a nucleolus organizer region (NOR) on each sex chromosome is probably an ancestral condition in the genus. Moreover, this difference in the variation of rDNA position among groups points out an interesting evolution question, which deserves further study.
