The ‘D. bakoue species complex’ Rafael, 1984 (‘D. montium species group’ Da Lage et al., 2007) comprises seven Afrotropical species. Using complete mitochondrial genome sequences and detailed morphological analysis, we revised the phylogenetic relationships between these species including two new ones. We found the ‘D. bakoue species complex’ to be a junior synonym of the ‘D. seguyi species complex’ Lachaise, 1971 and its seven species polyphyletic. We thus classified the species into three complexes, the ‘D. seguyi species complex’ comprises D. seguyi Smart, 1945, D. malagassya Tsacas & Rafael, 1982, D. curta Chassagnard & Tsacas, 1997 and D. chocolata sp. nov., the new ‘D. tsacasi species complex’ comprises D. tsacasi Bock & Wheeler, 1972 and D. seguyiana Chassagnard & Tsacas, 1997, and the new ‘D. vulcana species complex’ comprises D. vulcana Graber, 1957 and D. mylenae sp. nov. Drosophila bakoue Tsacas & Lachaise, 1974 could not be assigned to any of the defined complexes. The t...

large part of this work was done by the late Daniel Lachaise. The energy and knowledge of our former colleague and teacher has been a major driving force behind much of the research into Drosophilidae of islands of the western Indian Ocean and, indeed, the rest of Africa and to him we owe an enormous debt. [2003][2004][2005][2006] with the objective of assessing the current status of the biodiversity of the species of Drosophilidae in Seychelles.

We describe three new species of the Drosophila obscura species group, D. hypercephala, D. hideakii and D. quadrangula Gao & Toda, spp. nov., all discovered from high altitudes (>1500 m) on Mt Kinabalu, Sabah, Malaysia. These are the southernmost distribution records of the D. obscura group in the Oriental Region. The three new species are each morphologically similar to different species of the Old World D. obscura species subgroup. This suggests that they are descendants of different founder species that independently colonized the tropics from the subtropical or temperate zones during the glacial ages. The new species D. hypercephala is hypercephalic not only in males but also, although less distinct, in females, unlike other hypercephalic drosophilid species in which only males are hypercephalic. This new finding of a hypercephalic species from the subgenus Sophophora, of which species are relatively easy to culture in the laboratory and include the model species such as D. melanogaster and D. pseudoobscura, will promote genetic analyses on the development and the evolution of hypercephaly.
A survey of the genus Phortica Schiner from Kenya, Africa (Diptera: Drosophilidae)
Zootaxa, 2008
Nine species of the genus Phortica are found from Kenya, African, including two known and seven new species: Phortica (Allophortica) sexpunctata (Séguy, 1938), P. (Phortica) sobodo Burla, 1954, P. (P.) angulata sp. nov., P. (P.) curvispina sp. nov., P. (P.) machoruka sp. nov., P. (P.) manjano sp. nov., P. (P.) melanopous sp. nov., P. (P.) vinywelea sp. nov. and P. (P.) unispina sp. nov. The seven new species belong to the foliiseta species complex that is early found from the Oriental Region. A key to all Kenyan species is provided.

Accepté le 4 décembre 2019) Summary. The Drosophilid fauna has been less investigated in the Atlantic Afrotropical islands than in the Indian Ocean. Located about 250 km from the continent, the volcanic island of São Tomé has been colonized mostly by natural means, probably by the wind, since the emergence of the island about 15 million years ago, and presumably also by anthropogenic transportation of invasive and domestic species. To date, 37 different Drosophilid species have been mentioned from São Tomé. The present work extends this list to 80 species. The genera Zygothrica, Phorticella and Hypselothyrea are newly recorded from the island. Among these 80 species, only 12 are putatively introduced by human activities, suggesting the preponderance of natural arrivals. Compared to other islands, São Tomé harbours a high diversity of drosophilids. At least 14 species are supposed to be endemic. Future molecular comparisons between the island flies and their continental relatives will probably help to identify other endemic species. The high diversity observed in São Tomé is certainly due to the large size of the island, and to the presence of vast natural altitudinal forests offering a variety of possible habitats. Further collections are likely to lead to an increase of the species list. From now, São Tomé island appears as an excellent laboratory for studying the ecology and evolution of the Drosophila model. Résumé. Des collectes de terrain révèlent que São Tomé est l'île afrotropicale avec la plus grande diversité de drosophiles (Diptères : Drosophilidae). La faune de Drosophilidae a été moins étudiée dans les îles afrotropicales de l'Atlantique que dans l'océan Indien. Située à environ 250 km du continent, l'île volcanique de São Tomé a été colonisée principalement de façon naturelle, probablement à l'aide du vent, depuis l'émergence de l'île il y a environ 15 millions d'années, et par le transport supposé d'espèces domestiques et invasives par l'activité humaine. Jusqu'à présent, 37 espèces de Drosophilidae étaient mentionnées à São Tomé. Le présent travail accroît cette liste à 80 espèces. Les genres Zygothrica, Phorticella et Hypselothyrea sont nouvellement cités de l'île. Parmi ces 80 espèces, seulement 12 pourraient avoir été introduites par les activités humaines, révélant la prépondérance des colonisations naturelles. Comparée à d'autres îles, São Tomé abrite une plus grande diversité de drosophiles. Au moins 14 espèces sont supposées être endémiques. Il est probable que d'autres espèces endémiques seront identifiées lorsque les études moléculaires permettront de comparer les individus de São Tomé avec les espèces apparentées du continent africain. La diversité observée à São Tomé est certainement due à la grande taille de l'île et à la présence d'une vaste forêt d'altitude offrant une grande variété d'habitats. De futures collectes permettront d'accroître la liste d'espèces. L'île de São Tomé apparaît comme un excellent territoire pour l'étude de l'écologie et de l'évolution du modèle drosophile.

This paper describes the composition and abundance of Drosophila species found in three forest remnants in the State of São Paulo. A well-standardized sampling procedure applied on four collecting trips to the same sites on four areas resulted on 944 samples. All males collected were identified by analyses of the genitalia, this being the only data set used. One hundred and twenty five species were detected amongst the 29,289 males analyzed. From them 57,6% could be identified as described species. Thirteen of the species found were absent from the previous species list for the state of São Paulo State, thus represent an increase of 13% on the number known. We argue that the majority of the 53 unidentified species are in fact undescribed. The sites studied did not differ significantly in the proportion of identified species. On average identified species were almost seven times more abundant than unidentified ones, and this difference was significant. Rarefaction curve analysis confirmed that the proportion of unidentified species increase with sample size, and did not reach a plateau with our data set. These results illustrate the large richness of Drosophila species in forest remnants of São Paulo State. It also indicates that about half of the species in this region remain to be described. This conclusion is particularly important when one considers that this is a well studied genus of Diptera, on the best sampled region of Brazil.
Two new Neotropical species of Drosophila peruensis species group (Diptera, Drosophilidae)
Iheringia. Série Zoologia, 2011
The Drosophila peruensis species group was recently proposed and includes four taxa: D. atalaia Vilela & Sene, 1982, D. boraceia Vilela & Val, 2004, D. pauliceia Ratcov & Vilela, 2007, and D. peruensis Wheeler, 1959. All these species have most of setae or setulae of mesonotum arinsing from dark spots, wings with crossveins darker (except in D. atalaia) and hypandrium squared-shaped mostly fused to gonopods. Here, we describe two new species, Drosophila itacorubi sp. nov. and Drosophila paraitacorubi sp. nov., belonging to this species group. The male genitalia of these species are figured. An identification key to the D. peruensis species group is provided.
