“…The sex comb teeth of both D. bipectinata and D. parabipectinata are thicker and more prominent than in D. pseudoananassae and D. malerkotliana, where teeth are slightly tougher and thicker than the bristles (Figs 1a-4c). Species similarities in sex comb patterns are consistent with the phylogenetic relationship derived from cytological (Bock, 1971b), biochemical (Yang et al, 1972Hegde & Krishnamurthy, 1976), morphological (Mishra & Singh, 2006) and molecular studies (Kopp & Barmina, 2005). Further, the sex comb patterns of these four species is well in line with the hypothesis that "as far as phylogeny may be reconstructed, malerkotliana, pseudoananassae and a population ancestral to bipectinata and parabipectinata are derived directly from a common ancestral population" (Bock, 1971b).…”

Abstract. Understanding the genetic mechanisms of morphological evolution is one of the greatest challenges in evolutionary biology and for such studies sexually dimorphic traits in closely related species are of prime interest. In the Drosophila bipectinata species complex, which consists of four closely related species, namely D. bipectinata, D. parabipectinata, D. malerkotliana and D. pseudoananassae, the pattern of sex combs (a sexually dimorphic trait) is found to be highly diversified. The present investigation documents some unique and new sex comb phenotypes and demarcates intra-and interspecific variations in the sex comb pattern among the four species and their hybrids. There is remarkable similarity in sex comb pattern of D. bipectinata and D. parabipectinata but it differs from that of D. malerkotliana and D. pseudoananassae, which is in consistent with the phylogenetic relationships among the four species traced out by cytological, biochemical and molecular studies. The genetic basis of inheritance of sex comb patterns, its plausible implication with biogeographical distribution of species and the relationship between degree of hybridization and phylogenetic proximity have been addressed.

“…Although each two of the species are distinguished by almost the same number of fixed interspecific inversions, pairing between homologous polytene chromosome arms in interspecific hybrid larvae is very good in bipectinataparabipectinata, bipectinata-malerkotliana and parabipectinata-maferkotliana hybrids, but poor in the three hybrids involving pseudoananassae (Bock 1971), suggesting that the latter species is genetically somewhat removed from the other three. The same situation was indicated independently by the results of Yang et af.…”

“…Preliminary attempts at intercrossing the species of the bipectinata complex revealed that successful crosses could be effected in the laboratory, and analysis of the polytene chromosomal rearrangements in the hybrid larvae yielded some phylogenetic information concerning the species (Bock 1971). This paper reports the results of detailed systematic crosses and discusses the additional phylogenetic information that may be inferred from their results.…”

Although there is no evidence of hybridization in nature, interspecific crosses in all six possible pairwise combinations may be effected in the laboratory amongst the four species of the Drosophila bipectinata complex (D. bipectinata, D. parabipectinata, D. malerkotliana and D. pseudoananassae) of the Oriental-Australian biogeographic zones. Results range from a high degree of crossability in one direction with production of large numbers of sterile male and fertile female offspring in a 1 : 1 ratio (bipectinata x parabipectinata) to almost complete isolation in both directions; in the latter case (malerkotlianaxpseudoananassae) the very small proportion of successful crosses yielded only a few females oflow viability. These results combined with those previously obtained in polytene chromosomal and electrophoretic investigations suggest very close phylogenetic relationships among bipectinata, parabipectinata and malerkotliana, with a greater degree of divergence between these species and pseudoananassae.

A detailed comparison of its breakpoints and cytological configuration revealed that this inversion resembles the inversion 4 of Bock (1971), which was detected in laboratory populations originated from Thailand and the Philippines.…”

Drosophila bipectinata, a member of the melanogaster species group, is a common and wide-spread species in the Indian subcontinent. A geographic survey of inversion polymorphism has been carried out in Indian populations. Altogether, nine paracentric inversions are detected in the populations examined during this study. Of the nine inversions, two have been described earlier by Bock from laboratory populations established from Borneo, Thailand and the Philippines. The possible relationship between inversions and different environmental conditions is discussed.
