For at least the past 80my, Madagascar, a major biodiversity hotspot, has been isolated from all other landmasses. This long-term isolation, along with geologic and climatic factors within Madagascar and throughout the Indian Ocean, has undoubtedly influenced the evolution of the island's biota. However, few systematic analyses incorporating modern divergence dating and biogeographic analyses have focused on Madagascan insects. The diverse Madagascan millipede assassin bugs (Heteroptera: Reduviidae: Ectrichodiinae) offer an opportunity to contribute to a limited body of insect-related research that explores Madagascar's historical biogeography. A molecular dataset (COI mtDNA and 18S, 28S D2 and D3-D5 rDNAs) for 56 taxa (39 ingroup) and a combined morphological (145 characters) and molecular dataset for 110 taxa (93 ingroup) are analyzed with maximum likelihood (ML) and parsimony approaches. Based on the molecular ML phylogeny, divergence times were estimated using fossil and secondary calibrations and biogeographic analyses performed using DIVA, DEC, and DEC+j models to determine the role and patterns of vicariance and dispersal in the origin of Madagascan Ectrichodiinae. Results indicate that Ectrichodiinae in Madagascar do not form a monophyletic group, different clades are closely related to Afrotropical and Oriental lineages, and have colonized the island via transoceanic dispersal at least twice from the Oriental region and once from the Afrotropical region in the last ∼68my. Additionally, the DEC+j and DIVA models infer a single out-of-Madagascar dispersal event to the Afrotropical region. Oceanic and geologic factors that may have facilitated dispersal between these three regions are discussed. Results of the combined analyses are used to explore character support for Madagascan taxa and inform taxonomic diagnoses. Our results are congruent with the small but growing body of biogeographic research supporting Cenozoic transoceanic dispersal for Madagascan invertebrates to and from Oriental and Afrotropical regions.

“…Fungus-growing termites in Madagascar originated from a single colonization event ~7-11 mya (Nobre et al, 2010). Other studies on carpenter bees (Rehan et al, 2010), mayflies (Monaghan et al, 2005), pierid butterflies (Nazari et al, 2011), and dytiscid beetles (Bukontaite et al, 2015) have also supported Cenozoic colonization.…”

“…Supposed cases of dispersal into or out of Madagascar among insects were found, for multiple colonization events out of Africa in the case of the butterfly genera Charaxes Ochsenheimer (apart from the one Polyura Billberg of possible Asian origin) (Aduse‐Poku et al ., ) and Colotis Hübner (Nazari et al ., ), whereas cases of Malagasy generation of evolutionary novelty have been noted in the Papilio demoleus Linnaeus group of swallowtails (Zakharov et al ., ) and for diving beetles (Bukontaite et al ., ). Syntomines seem to provide yet another case where both trajectories have been followed, with the stepwise origin of evolutionary novelty in the case of the massive syntomine radiation on the island.…”

“…These findings suggest a significant role for Madagascar as a distribution source for organisms, influencing the biodiversity of the African continent, as was postulated by Bukontaite et al . (). Further studies will be needed to investigate these findings, which suggest a much more complicated taxonomic structure of the tribe and multiple hidden events reflecting its current distribution patterns across the Old World continents.…”

The Old World tribe Syntomini is the most neglected of the three major groups of the subfamily Arctiinae -the most megadiverse lineage (c. 11 000 species) of the superfamily Noctuoidea, comprising about a quarter of its entire species diversity. In none of the previous morphogenetic studies was Syntomini (which are often conspicuously spotted, aposematic moths) sampled adequately enough to provide information about the tribe's systematic diversity and relationships above species level. As such data are of crucial importance for a comprehensive understanding of arctiine diversity and evolution, we have investigated the relationships of the major lineages of Syntomini based on up to eight mitochondrial and nuclear genes and 91 species, representing 39 genera. We cover most of the known genera and major geographic regions, including, for the first time, Madagascar, where there is a significant syntomine radiation. We find that the thyretines, in particular, which are restricted to the Afrotropical region, are paraphyletic. As a result we propose to treat Thyretina syn.n. (Thyretini sensu Przybyłowicz, 2009) as an artificial assemblage and synonymize it under Syntomini. Thyretes Boisduval and Pseudothyretes Dufrane stand on their own close to the Madagascan radiation, whereas all but one of the Madagascan syntomines comprise a monophylum, with the genus Fletcherinia Griveaud instead being related to at least one species of Ceryx Wallengren in Africa. Also surprising from a biogeographical point of view is that the genus Dysauxes Hübner, which includes the European Handmaiden moth, is nested within the Madagascan radiation. Our study also makes it clear that much more detailed studies are needed to revise not only Ceryx from Asia and Africa but the Afrotropical syntomine genera, many of which do not form clades in our phylogenetic reconstruction, and to further inventory the diversity that is present in the Afrotropics. Based on our results, we consider Thyretarctia Strand stat. rev., Daphaenisca Kiriakoff stat.n. and Callobalacra Kiriakoff stat.n. as valid genera. We also move Anapisa Kiriakoff and return Meganaclia Aurivillius and Nacliodes Strand to Syntomini. 624

Leptotina butterflies (Lycaenidae, Polyommatiinae) are found mostly in tropical and subtropical areas around the globe, marginally penetrating into temperate regions. Here, we investigated phylogenetic and biogeographical relationships of most representatives of the subtribe, using both likelihood and Bayesian approaches. We also estimated the timing of their diversification. And lastly, we studied phylogeographic patterns of the most widespread species, Leptotes pirithous. DNA sequences from two mitochondrial (COI, COII) and two nuclear genes (wingless, Ef1 ) were analysed for 13 species of the genus Leptotes Scudder and one species of the genus Cyclyrius Butler. Both genera together form a monophyletic clade, and Cyclyrius is rooted deep inside Leptotes. Therefore, we designate Cyclyrius to be a junior synonym of Leptotes. According to our study, the genus Leptotes originated between the late Eocene and early Oligocene (35-31 Ma). During the Miocene it dispersed to the rest of the southern hemisphere, with further speciation events within the Indo-Australian region, and separate radiations in the Americas and the Afrotropics. Leptotes webbianus from the Canary Islands turned out to be sister to the American clade from which it split c. 12 Ma. Leptotes pirithous originated in Madagascar c. 4 Ma and invaded the whole of Africa and southern Europe, including numerous surrounding islands. Populations of L. pirithous from Mauritius and Madagascar turned out to represent a distinct species (Leptotes durrelli sp.n.) and the same applies to the Australasian populations of Leptotes plinius (Leptotes lybas stat. rev.).
