“…and 9 calibration points) the polychaeta lineage is the sister group to all other species groups, a topology consistent with previous studies [15], [54], [58]. On the other hand, the remaining BI and ML analyses place the polychaeta as the sister group to the clade comprising the repleta , annulimana , nannoptera , dreyfusi , canalinea and mesophragmatica , a relationship observed previously with mitochondrial markers [54]. The sister relationship between the Hawaiian Drosophila and the virilis group recovered in the BI analysis (218 spp., 9 calibration points) is novel, nevertheless this is not supported by the BPP.…”

Colonisation of new geographic regions and/or of new ecological resources can result in rapid species diversification into the new ecological niches available. Members of the subgenus Drosophila are distributed across the globe and show a large diversity of ecological niches. Furthermore, taxonomic classification of Drosophila includes the rank radiation, which refers to closely related species groups. Nevertheless, it has never been tested if these taxonomic radiations correspond to evolutionary radiations. Here we present a study of the patterns of diversification of Drosophila to test for increased diversification rates in relation to the geographic and ecological diversification processes. For this, we have estimated and dated a phylogeny of 218 species belonging to the major species groups of the subgenus. The obtained phylogenies are largely consistent with previous studies and indicate that the major groups appeared during the Oligocene/Miocene transition or early Miocene, characterized by a trend of climate warming with brief periods of glaciation. Ancestral reconstruction of geographic ranges and ecological resource use suggest at least two dispersals to the Neotropics from the ancestral Asiatic tropical disribution, and several transitions to specialized ecological resource use (mycophagous and cactophilic). Colonisation of new geographic regions and/or of new ecological resources can result in rapid species diversification into the new ecological niches available. However, diversification analyses show no significant support for adaptive radiations as a result of geographic dispersal or ecological resource shift. Also, cactophily has not resulted in an increase in the diversification rate of the repleta and related groups. It is thus concluded that the taxonomic radiations do not correspond to adaptive radiations.

“…Our age estimates correlate well with geological events that could have been responsible for putative allopatric speciation events. The origin of the virilis group has been placed in East Asia (Throckmorton, 1982;Vieira and Charlesworth, 1999;Wang et al, 2006). According to our age estimates, the ancestral species of the montana phylad (represented by D. montana in the present analysis), formed by Nearctic species with the exception of D. montana that has a Nearctic and Palearctic distribution, started to diverge from the other species around 10 Mya (6.2-15.9 Mya 95% confidence interval; Fig.…”

“…Total DNA was extracted from muscle tissue with the method of Boom et al (1990). For amplifying ND2 from H. diekei and for sequencing, primers ND2-H (5Ј-AAGCTACTGGGTTCATACC-3Ј) (Wang et al 2006) and ND2-sub9.5r (5Ј-TYATY CAYTTRGGGAARAATCCTAA-3Ј) (Kobayashi et al 2009) were used. Polymerase chain reaction (PCR) conditions were 94ЊC for 7 min; 35 cycles of 94ЊC for 45 s, 42ЊC for 90 s, and 72ЊC for 2 min; and 72ЊC for 7 min.…”

Divergent natural selection on different host plants may be a crucial factor in promoting the remarkable diversity of phytophagous insects, and might occur in any geographical context. Because the intensity and consequences of divergent selection on different hosts can vary depending on the degree of gene flow between conspecific insect populations, elucidating the geographical context and degree of host specificity in the incipient phase of differential host use is indispensable to understanding the diversification process in phytophagous insects. Henosepilachna diekei Jadwiszczak & Węgrzynowicz (Coleoptera: Coccinellidae) is a tropical ladybird beetle occurring mainly on two host species from different plant families, Asteraceae and Lamiaceae. We investigated the geographical distribution of H. diekei across Java, Indonesia, in relation to the availability of the two hosts, and examined the host specificity of beetles in the laboratory. We also investigated genetic relationships among local populations of beetles using mitochondrial NADH dehydrogenase subunit 2 gene sequences. Geographic variation in host use by H. diekei was largely determined by skewed geographical distributions of the hosts, although there was a synergistic effect with extremely divergent host specificity by the beetles. The molecular analyses suggested that genetic differentiation among the beetle populations has occurred and has been maintained by the effects of both geographical distance and divergent host specificity. The geographical distribution of H. diekei populations differing in host specificity suggests that geographical distance, local host-plant availability, and divergent host specificity contribute synergistically to promote the genetic differentiation and subsequent diversification of phytophagous insects on different hosts.
