Data from: The first record of a trans-oceanic sister-group relationship between obligate vertebrate troglobites

Prosanta Chakrabarty, Matthew P. Davis & John S. Sparks
We show using the most complete phylogeny of one of the most species-rich orders of vertebrates (Gobiiformes), and calibrations from the rich fossil record of teleost fishes, that the genus Typhleotris, endemic to subterranean karst habitats in southwestern Madagascar, is the sister group to Milyeringa, endemic to similar subterranean systems in northwestern Australia. Both groups are eyeless, and our phylogenetic and biogeographic results show that these obligate cave fishes now found on opposite ends of...

Data from: Correlated evolution of mating system and floral display traits in flowering plants and its implications for the distribution of mating system variation

Carol Goodwillie, Risa D. Sargent, Susan Kalisz, Richard H. Ree, David A. Moeller, Mario Vallejo-Marin, Christopher G. Eckert, Alice A. Winn, Elizabeth Elle, Monica A. Geber & Mark O. Johnston
Reduced allocation to structures for pollinator attraction is predicted in selfing species. We explored the association between outcrossing and floral display in a broad sample of angiosperms. We used the demonstrated relationship to test for bias against selfing species in the outcrossing rate distribution, the shape of which has relevance for the stability of mixed mating. Relationships between outcrossing rate, flower size, flower number and floral display, measured as the product of flower size and...

Data from: New species and new records of Mydidae from the Afrotropical and Oriental regions (Insecta, Diptera, Asiloidea)

Torsten Dikow
New Mydidae species are described from the Afrotropical and Oriental regions including the first records of this family from several countries in eastern Africa (Kenya, Tanzania, and Uganda) and Mauritania in western Africa as well as Nepal and Thailand in Asia. The new species are, Leptomydinae: Leptomydas notos sp. n. (south-western India), Leptomydas rapti sp. n. (south-central Nepal), Leptomydas tigris sp. n. (north-central Thailand); Syllegomydinae: Mydaselpidini: Mydaselpis ngurumani sp. n. (south-eastern Kenya, north-eastern Tanzania), Vespiodes...

Data from: Two new species of Lecanora sensu stricto (Lecanoraceae, Ascomycota) from east Africa

Paul Kirika, Sittiporn Parnmen & Thorsten Lumbsch
The new sorediate species Lecanora kenyana from Mount Kenya and Lecanora orientoafricana from the Rift Valley in Kenya are described. Lecanora kenyana has red-brown apothecia with a constricted base, a melacarpella–type amphithecium, pulicaris–type epihymenium, a hyaline hypothecium, and contains usnic acid as major constituent. Lecanora orientoafricana is characterized by having a dark hypothecium, pulicaris-type amphithecium, chlarotera-epihymenium, and contains atranorin and gangaleoidin. A phylogenetic analysis using maximum likelihood and a Bayesian approach based on DNA sequence...

Data from: Taxonomic revision of Ectyphus Gerstaecker, 1868 and Parectyphus Hesse, 1972 with a key to world Ectyphinae (Insecta, Diptera, Mydidae)

Kathleen Lyons & Torsten Dikow
The Afrotropical Mydidae genera Ectyphus Gerstaecker, 1868 and Parectyphus Hesse, 1972 are revised. Six species of Ectyphus are recognised (E. abdominalis Bezzi, 1924, E. armipes Bezzi, 1924, E. capillatus Hesse, 1969, E. pinguis Gerstaecker, 1868, and E. pretoriensis Bezzi, 1924), of which one is newly described from Kenya, E. amboseli sp. n. Two species, E. bitaeniatus Hesse, 1969 and E. flavidorsalis Hesse, 1969, are newly synonymised with E. pinguis. The monotypic genus Parectyphus Hesse, 1972...

Data from: Millipede taxonomy after 250 years: classification and taxonomic practices in a mega-diverse yet understudied arthropod group

Michael S. Brewer, Petra Sierwald & Jason E. Bond
BACKGROUND: The arthropod class Diplopoda is a mega-diverse group comprising >12,000 described millipede species. The history of taxonomic research within the group is tumultuous and, consequently, has yielded a questionable higher-level classification. Few higher-taxa are defined using synapomorphies, and the practice of single taxon descriptions lacking a revisionary framework has produced many monotypic taxa. Additionally, taxonomic and geographic biases render global species diversity estimations unreliable. We test whether the ordinal taxa of the Diplopoda are...

Data from: Biodiversity inventories and conservation of the marine fishes of Bootless Bay, Papua New Guinea

Joshua A. Drew, Charlene L. Buxman, Darcae D. Holmes, Joanna L. Mandecki, Augustine J. Mungkaje, Amber C. Richardson & Mark W. Westneat
BACKGROUND: The effective management and conservation of biodiversity is predicated on clearly defined conservation targets. Species number is frequently used as a metric for conservation prioritization and monitoring changes in ecosystem health. We conducted a series of synoptic surveys focusing on the fishes of the Bootless Bay region of Papua New Guinea to generate a checklist of fishes of the region. Bootless Bay lies directly south of Port Moresby, the capital of Papua New Guinea,...
