Significant Step

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 two new species are endemic to Madagascar and we report the presence of D. seguyi and D. curta in Mayotte and Madagascar, respectively. The results hence represent a significant step towards understanding the diversity and evolution of this species group in Africa and the islands of the Western Indian Ocean.

Time Information

Mite predators of synanthropic flies similar to Macrocheles kraepelini (Berlese) are described as a new complex of species belonging to the Macrocheles glaber species group. Two new species in the kraepelini complex are described, M. tantalus and M. hallidayi. The male of M. kraepelini is described for the first time. Information on the distribution and phoretic associations of all three species is presented. Macrocheles hallidayi and M. kraepelini are sibling species, which, when sympatric, differ in adult body size by the same ratio as the holarctic sibling species pair of M. perglaber and M. glaber.

The aim of this study is to conduct a detailed taxonomic revision of the Poecilimon (Poecilimon) zonatus species-group (Orthoptera: Phaneropterinae) using both morphology and bioacoustics. Two new species (Poecilimon (Poecilimon) salmani, P. (P) azizsancar) and one new subspecies (P. (P) zonatus datca) are described. Based on the data, we conclude that the species complex can be separated into two subgroups (P. tauricola and P. zonatus). Within the P. zonatus subgroup, song structures indicate P. variicercis as basal branch since producing two syllable types is possibly a derived character. From both, from bioacoustics and morphology, it is concluded that the relationships between species of the group are as follows: P. tauricola subgroup (P. tauricola + P. azizsancar) + P. zonatus subgroup (P. variicercis + (P. varicornis + (P. zonatus zonatus+P. zonatus datca)) + (P. salmani+P. vodnensis)))). Except for two species (P. vodnensis and P. varicornis), the other species of the group are all distributed in Anatolia. P. vodnensis is known only from Macedonia, whereas, P. varicornis has been recorded only from Syria and Lebanon. We assume that the group originated from an Anatolian ancestral stock and expanded its distribution to the Balkans through Taurus Way and Dardanelles. Other ancestral populations may have also spread in the north-south directions through the appropriate steppe corridors in the Anatolian Diagonal Mountains and in its vicinity.

Three species of the pagurid hermit crab genus Pagurixus Melin, 1939, are reported from Europa Island in the Mozambique Strait, western Indian Ocean: P. haigae Komai & Osawa, 2007, P. annulus n. sp., and P. europa n. sp. Pagurixus haigae is recorded from the western Indian Ocean for the first time. Pagurixus annulus n. sp. and P. europa n. sp. are referred to the P. boninensis (Melin, 1939) species group and P. anceps (Forest, 1954) group, respectively. Diagnostic characters of these two new species are discussed.

A New Species

A new species of the copepod genus Tortanus (Atortus) (Copepoda: Calanoida), T. (A.) insularis, is described from the coastal region of Rodrigues Island, Mauritius, an isolated island in the south-western Indian Ocean. This new species can be assigned to an Indian faunal element, the recticauda species group, in the Indo-West Pacific recticauda species complex. It exhibits the closest relationship to T. (A.) recticauda recorded from the southern Red Sea and Arabian Gulf, rather than the closer distributed T. (A.) capensis, recorded from off South Africa.

High Diversity

A new species of the planktonic copepod Tortanus (Atortus) (Calanoida: Tortanidae), T. (A.) magnonyx is described from the Seychelles, Mauritius and Madagascar. This is the sixth species of the Indian Ocean recticauda species group, of the Indo-West Pacific recticauda species complex, that has been described from the western Indian Ocean. The inshore areas where these copepods are found have been poorly surveyed, so the number of species found implies a high diversity.
