Abstract
Species of Tetraserica chafers (Coleoptera: Scarabaeidae: Sericini) can easily be distinguished by the distinct shape of strongly divergent male genitalia; however, it was so far unclear if such divergent copulation organs may avoid hybridisation. Here, we analysed an 826 bp fragment of the mitochondrial cytochrome c oxidase subunit 1 (COI) for a total of 113 Tetraserica individuals out of 38 morphospecies from 33 localities in Southeast Asia. DNA-based species delimitation was performed using statistical parsimony network analysis (TCS), Poisson tree processes (PTP) model, Automatic Barcode Gap Discovery (ABGD) and the generalised mixed Yule-coalescent (GMYC) model. The different approaches for DNA-based species delimitation revealed different numbers of molecular operational taxonomic units (MOTUs) and showed low congruence with a priori assigned morphospecies. GMYC and PTP generally tended to lump morphospecies while ABGD and TCS more often split morphospecies. TCS revealed the highest congruence between MOTUs and morphospecies. While incongruence of species hypotheses was discussed in the context of incomplete lineage sorting and introgression, we could identify two unexpected cases in which introgression occurred between species with highly dissimilar morphology of the male genitalia and that resulted in lumping with DNA-based species delimitation. Most other cases of not matching morphospecies and MOTUs represent young speciation in which standard markers (CO1) do not yet fit the morphological signal of divergence, as reflected by male copulation organs.

El genero Neotropical Pseudopimelodus es el segundo con la mas amplia distribucion de la familia Pseudopimelodidae en Sur America y comprende cuatro especies validas que habitan en diferentes rios trans y cis-andinos. De estas cuatro especies, dos se encuentran registradas en Colombia: P. schultzi distribuida en las cuencas Magdalena-Cauca y Caribe y P. bufonius en el rio Atrato y en las cuencas Amazonas y Orinoco. Diversos procesos paleogeograficos resultantes de la orogenia Andina en Surameric...

: Accurate delimitation of species is crucial for a stable taxonomy, which provides the foundation for the study of evolutionary biology, ecology, and essentially all biological disciplines. Several approaches toward impartial and repeatable taxonomic practices are available but all existing methods have potentially unacceptable shortcomings. In particular, problems can arise when the underlying model assumptions are violated, for instance, in the presence of reduced gene flow. This is observed ...

The standard bootstrap (SBS), despite being computationally intensive, is widely used in maximum likelihood phylogenetic analyses. We recently proposed the ultrafast bootstrap approximation (UFBoot) to reduce computing time while achieving more unbiased branch supports than SBS under mild model violations. UFBoot has been steadily adopted as an efficient alternative to SBS and other bootstrap approaches. Here, we present UFBoot2, which substantially accelerates UFBoot and reduces the risk of ove...

External male reproductive structures have received considerable attention as a cause of reproductive isolation (RI), because the morphology of these structures often evolves rapidly between populations. This rapid evolution presents the potential for mechanical incompatibilities with heterospecific female structures during mating and could thus prevent interbreeding between nascent species. Although such mechanical incompatibilities have received little empirical support as a common cause of RI...

Megadiverse insect groups present special difficulties for biogeographers because poor classification, incomplete knowledge of taxonomy, and many undescribed species can introduce a priori sampling bias to any analysis. The historical biogeography of Sericini, a tribe of melolonthine scarabs comprising about 4000 species, was investigated using the most comprehensive and time-calibrated molecular phylogeny available today. Problems arising through nomenclatural confusion were overcome by extensi...

Abstract The multispecies coalescent model underlies many approaches used for species delimitation. In previous work assessing the performance of species delimitation under this model, speciation was treated as an instantaneous event rather than as an extended process involving distinct phases of speciation initiation (structuring) and completion. Here, we use data under simulations that explicitly model speciation as an extended process rather than an instantaneous event and carry out species d...

Motivation: In recent years, molecular species delimitation has become a routine approach for quantifying and classifying biodiversity. Barcoding methods are of particular importance in large-scale surveys as they promote fast species discovery and biodiversity estimates. Among those, distance-based methods are the most common choice as they scale well with large datasets; however, they are sensitive to similarity threshold parameters and they ignore evolutionary relationships. The recently intr...
