“…However, they are very similar in morphology, hardly distinguishable from each other even by a few characters designated as the diagnosis, especially between D. lini and D. ohnishii , implying that they are still in the process of species differentiation, even though having reached almost to the level of good species. This is supported also by partial crossability and fertility of F 1 hybrids between them (Kim et al ., 1989;Oguma et al ., 1995).…”

“…In this study, we examined morphological differences among three sibling species that had proved to be biologically good species reproductively isolated from each other almost completely (Kim et al ., 1989;Oguma et al ., 1995). Of those three species, two were described as new species, i.e .…”

“…This subgroup includes a variety of species at different stages of speciation process and provides very useful materials for studies of evolutionary genetics. The relationships among members of this subgroup have been investigated by various methods; hybridization (cross experiment) tests (David et al , 1978;Kim et al ., 1989), two dimensional electrophoresis and conventional starch gel electrophoresis (Ohnishi et al, 1983a, b;Ohnishi and Watanabe, 1984), chromosomal (metaphase karyotype) analysis (Baimai and Chumchong, 1980;Baimai et al, 1986), and eco-physiological comparison (Kimura, 1987). Through these studies several groups of very closely related species have been recognized as species-complexes: the D. auraria, the D. bakoue , the D. bocqueti, the D. jambulina , the D. kikkawai , the D. nikananu and the D. serrata complex.…”

“…They placed MMY326 as a member of the kikkawai complex and tentatively named it as Drosophila lini -like. Then, Kim et al (1989) examined the crossability between D. lini and D. linilike (MMY326), and revealed that the premating isolation between them was almost complete. Furthermore, Kim et al (1993) examined restriction enzyme patterns of mitochondrial DNA in 18 species of the montium subgroup, and placed D. lini -like (MMY326) closest to D. lini .…”

-Morphological differences are investigated using several culture strains of three sibling species collected from Taiwan and Guangdong in China and Pyinoolwin and Yangon in Myanmar. Careful examination of male terminalia reveals distinguishable differences in the paramere and the aedeagal basal process among the three species. In addition, a number of quantitative characters are compared. KruskalWallis tests with Bonferroni correction, which are carried out separately for each sex, detect significant differences in 15 characters, of which two are male-specific, among the three species. Canonical discriminant analysis using these characters reveals that the three species can be distinguished from each other with high confidence for both sexes. The results clearly show the presence of three good species, Drosophila ( Sophophora ) lini Bock & Wheeler, 1972 and its two new siblings. The new species are described as Drosophila ( Sophophora ) ohnishii sp. nov. from Pyinoolwin and Drosophila ( Sophophora ) ogumai sp. nov. from Yangon. The morphological differentiation among the three sibling species does not coincide with the degree of reproductive isolation (based on a previous study). The premating isolation pattern suggests two possibilities that premating isolation has been evolved or reinforced in sympatric populations between D. ohnishii and D. lini and between D. ohnishii and D. ogumai or that it has evolved in a very restricted local population of D. ohnishii , possibly by a few mutations.

Phylogenetic utility of the mitochondrial COI (cytochrome oxidase subunit I) and nuclear Gpdh (glycerol-3-phosphate dehydrogenase) genes was studied in the Drosophila melanogaster species group. The rate of substitution was higher in the COI gene than in the Gpdh gene. In addition, multiple substitutions, not only for transitional but also for transversional substitutions, occurred faster in the COI gene. None of the trees obtained using the COI gene supported the well-established monophyly of the ananassae subgroup. In addition, the incongruence length difference test, Templeton test, and partitioned Bremer support revealed that the trees based on the COI data are considerably different from those based on the Gpdh and the combined data set. Thus, the COI gene did not show good phylogenetic performance in the melanogaster group. The present analyses based on the Gpdh gene and the combined data set revealed that the ananassae subgroup branched off first in the melanogaster group followed by the montium subgroup and further by the melanogaster subgroup in contrast to the most recent phylogenetic hypothesis based on Amy multigenes.
