Data from: Hidden island endemic species, and their implications for cryptic speciation within soil arthropods
<p><strong>Aim:</strong> Specialisation to the soil environment is expected to constrain the spatial scale of diversification within animal lineages. In this context, the existence of flightless arthropod lineages, adapted to soil environments, but with broad geographic ranges, represent something of an anomaly. Here we investigate the diversification process within one such 'anomalous' soil specialist: <em>Geomitopsis franzi </em>Coiffait, 1978, an eyeless and flightless beetle species strongly adapted to the endogean environment but distributed across several oceanic islands.</p> <p><strong>Location:</strong> Canary Islands</p> <p><strong>Taxon:</strong> <em>Geomitopsis</em> (Coleoptera, Staphylinidae)</p> <p><strong>Methods:</strong> We performed an integrative study, including molecular phylogenetics, population genomics, and morphometry. Four DNA regions (two mitochondrial and two nuclear) were amplified and sequenced for 159 specimens from 58 localities sampled across five islands for phylogenetic analyses, and a dated phylogenetic tree was obtained using a mitogenome dataset<em>. </em>ddRAD-seq data was generated to evaluate mtDNA lineages in sympatry against the biological species concept.</p> <p><strong>Results:</strong> We found high levels of genetic differentiation (>8% COI gene divergence) among populations from different islands and among geographically coherent lineages within single islands. Lineages within Tenerife presented significant patterns of isolation by distance, with ddRAD-seq providing evidence that lineages represent biological species. Morphometric analyses revealed limited variation, with most lineages lacking diagnostic characters.</p> <p><strong>Main conclusions:</strong> <em>Geomitopsis franzi</em> is comprised of at least seven lineages that merit consideration as biological species, and is best considered as a complex of cryptic species. The limited morphological variation across these lineages is consistent with adaptation to the endogean environment placing strong constraints on morphological change. The evolution of cryptic species should be favoured when such constraints are coupled with limited dispersal ability, which characterises <em>G. franzi</em>, and is a trait that broadly characterises the soil mesofauna. We suggest that cryptic species diversity is likely to be a recurrent feature across soil adapted arthropod species with range sizes that appear inconsistent whith a low potential for dispersal.</p>

Distribution. Endemic to the Rwenzori Mountains in W Uganda. Distribution is not believed to overlap with other duikers in the C. nigrifrons group as once thought; records of C. rubidus from Rwanda likely refer to the Black-fronted Duiker subspecies (C. maigrifrons kivuensis); this latter species is absent from the Rwenzoris. in Bovidae

FIGURE 23 in A new, narrowly endemic species of swamp-dwelling dusky salamander (Plethodontidae: Desmognathus) from the Gulf Coastal Plain of Mississippi and Alabama
FIGURE 23. Possible specimen of Desmognathus pascagoula (AUM 10543) from near Tensaw, Baldwin Co., Alabama in dorsal (a) and ventral (b) views. Key features suggesting conspecificity with the Pascagoula populations are a relatively blunt or brachycephalic snout; distinct postocular stripe (faded in preservative, but of an apparently bright color in life); distinct dorsal color pattern; jagged but noticeable ventrolateral and lateral "portholes" on the trunk and tail(appearing as light areas devoid of melanin); ventral melanophores in the "stellate" condition; and heavily keeled, "fin-like" or "blade-like" tail with distinct dorsal coloration.

FIGURE 21. Larger specimen (MMNS 19993/RAP1112) of Desmognathus valentinei from headwaters of West Creek, Harrison Co., Mississippi, beginning to showing typical adult coloration of "dark auriculatus" sensu Valentine (1963) more typical of southeastern Mississippi populations. Note the more uniform and darker dorsal coloration and more brightly contrasting "portholes" in all three rows on the trunk.

FIGURE 22. Large specimen (MMNS 19994/RAP1113) of Desmognathus valentinei from headwaters of West Creek, Harrison Co., Mississippi, showing typical adult coloration of "dark auriculatus" sensu Valentine (1963). Note the uniform melanistic dorsal coloration and brightly contrasting ventrolateral "portholes" on the trunk, nearly indistinguishable postocular stripe, and strongly keeled "fin-like" or "blade-like" tail, with lateral row of "portholes" barely visible.

FIGURE 19. Small specimen (MMNS 19990/RAP1109) of Desmognathus valentinei from Thompson Creek, Wayne Co., Mississippi, showing typical juvenile form and color of "pale auriculatus" sensu Valentine (1963), notably a blunt snout; indistinct postocular stripe; indistinct dorsal color pattern; distinct ventrolateral and lateral "portholes" on the trunk and tail; and distinctly keeled, "fin-like" or "blade-like" tail (partially regrown).

FIGURE 20. Large adult specimen (MMNS 19991/RAP1110) of Desmognathus valentinei from Thompson Creek, Wayne Co., Mississippi, showing typical adult coloration of "pale auriculatus" sensu Valentine (1963). Note overall distinctiveness in body form and coloration from D. pascagoula, including muted coloration of the postocular stripe, girth of the trunk and tail, distinctiveness of all three rows of "portholes" on the trunk, and lack of distinct dorsal color pattern.
