Fig. 2 in First Records of a Rare Deep-sea Anglerfish, Himantolophus azurlucens, from the Western North Pacific, with Comments on the DNA Barcodes of the Genus (Lophiiformes: Himantolophidae)
Fig. 2. Neighbor-joining tree based on sequence variations of the partial mitochondrial DNA COI gene and escal appendages of representative specimens. Sequences indicated by catalog numbers of specimens (determined here in bold italic) or INSDIC/BOLD registration numbers (determined in previous studies—see Table 1). Numbers at branches indicate bootstrap probabilities following 1000 bootstrap replications. Scale bar equals 0.01 of uncorrected p-distance. Photos were provided by the CSIRO Australian National Fish Collection (CSIRO specimens) and A. L. Stewart (NMNZ specimens).

Species delimitation with limited sampling: an example from rare trapdoor spider genus Cyclocosmia (Mygalomorphae, Halonoproctidae)
<p>The outcome of species delimitation depends on many factors, including conceptual framework, study design, data availability, methodology employed, and subjective decision-making. Obtaining sufficient taxon sampling in endangered or rare taxa might be difficult, particularly when non-lethal tissue collection cannot be utilized. The need to avoid overexploitation of the natural populations may thus limit the methodological framework available for downstream data analyses and bias the results. We test species boundaries in rare North American trapdoor spider genus <em>Cyclocosmia</em> Ausserer (1871) inhabiting the Southern Coastal Plain biodiversity hotspot with the use genomic data and two multispecies coalescent model methods. We evaluate the performance of each methodology within a limited sampling framework. To mitigate the risk of species over-splitting, common in taxa with highly structured populations, we subsequently implement a species validation step via genealogical diversification index (gdi), which accounts for both genetic isolation and gene flow. We delimited eight geographically restricted lineages within North American <em>Cyclocosmia</em>, suggesting that major river drainages in the region are likely barriers to dispersal. Our results suggest that utilizing BPP in the species discovery step might be a good option for datasets comprising hundreds of loci, but fewer individuals, which may be a common scenario for rare taxa. However, we also show that such results should be validated via gdi, in order to avoid over-splitting.</p>

Rare and widespread: Integrating Bayesian MCMC approaches, Sanger sequencing and Hyb-Seq phylogenomics to reconstruct the origin of the enigmatic Rand Flora genus Camptoloma
<p class="MsoCommentText">Premise</p> <p class="MsoCommentText">Genera that are widespread but have a geographically discontinuous distribution and are represented by few species are intriguing. Did they achieve their disjunct distribution recently, or is it ancient in origin? Why are they species-poor? The Rand Flora is a continental-scale floristic pattern in which closely related species appear co-distributed in isolated regions over the edges of Africa and nearby archipelagos. Genus <i>Camptoloma</i> (Scrophulariaceae) is the most notable example, comprising three species isolated from each other at the ends of the African continent: <i>C. canariense </i>in the west, endemic to the Canary Islands; <i>C. lyperiiflorum </i>in the east, endemic to the Horn of Africa - Southern Arabia; and <i>C. rotundifolia</i>, restricted to Southern Africa.</p> <p class="MsoCommentText">Methods</p> <p class="MsoCommentText">Here, we employed Sanger sequencing of nuclear and plastid markers, together with genomic target sequencing of 2190 low-copy nuclear genes, to infer interspecies relationships and the position of <i>Camptoloma</i> within Scrophulariaceae, using supermatrix and multispecies-coalescent approaches. Lineage divergence times and ancestral ranges were inferred with Bayesian MCMC approaches. Population history was estimated with phylogeographic structured coalescent methods.</p> <p class="MsoCommentText">Key Results</p> <p class="MsoCommentText">Our results support <i>C. rotundifolia</i> as sister to the disjunct clade formed by <i>C. canariense</i> and <i>C. lyperiiflorum.</i> Stem divergence was dated in the Late Miocene, while the origin of extant diversification within the genus was inferred as Early Pliocene.</p> <p class="MsoCommentText">Conclusions</p> <p>We show that the current disjunct distribution of <i>Camptoloma </i>across Africa was likely the result of fragmentation and extinction/population bottlenecking events associated to historical aridification cycles, consistent with the "climatic refugia" hypothesis.</p>
