Laniger bat tick (Ixodes lanigeri), new hard tick species (Ixodidae) from mouse-eared bats (Myotis) in Vietnam

NEWS - Researchers have identified Ixodes ticks from Vietnam based on morphological and molecular characteristics of females, nymphs and larvae as a new species, laniger bat tick ( Ixodes lanigeri ), which like other members of the Ixodes ariadnae complex appears to show a preference for vesper bats as a typical host. Historically, for more than a century and a half, only one species has been called the “long-legged bat tick”: Ixodes vespertilionis Koch. However, over the past decade, it has been molecularly recognized that long-legged ixodid ticks associated with bats may represent at least six species. Host associations and geographic separation may explain the evolutionary divergence of the new species from its closest living relative Murina hilgendorfi Peters in East Asia, Japan, as no Myotis or Murina spp. have overlapping distributions between Vietnam and the Japanese mainland. On the other hand, assuming that I. lanigeri may be present in other myotine bats and knowing that s

Whipple’s Cryptantha (Cryptantha whippleae), serpentine-adapted species endemic to northern California

NEWS - Whipple’s Cryptantha ( Cryptantha whippleae ) is described as a new species from a meandering barren area in the Shasta-Trinity National Forest in Siskiyou County, California, with one outlier population in a meandering area possibly in Lake County, California. Cryptantha is a genus of perennial herbs in the Boraginaceae (Amsinckiinae) and has been non-monophyletic in several molecular phylogenetic studies. It is currently recognized with 109 species and 124 minimum-ranked taxa, of which 63 are in North America and 47 are in South America, with one taxon found on both continents. Serpentine soils, particularly in northern California, are formed from ultramafic (meta-igneous) rocks that formed millions of years ago on the seafloor. These soils are very high in heavy metals (e.g., nickel, iron, and magnesium) and low in calcium and potassium. Serpentine soils are unsuitable for plants that have not evolved to tolerate the harsh conditions. Species that adapt to serpentines have h

Large pro rotifer (Proales amplus), new monogonont with large epipharynx from Korea (Rotifera, Proalidae)

NEWS - Large pro rotifer ( Proales amplus ) is the 42nd species in the genus Proales that exhibits unique morphological characteristics on the trophy, especially the unmatched epipharynx that prevents misidentification with other species. The epithet amplus is derived from the Latin word meaning large or wide, referring to the size and shape of the epipharynx. Proalidae Harring & Myers 1924 includes 4 genera and 53 species that are distributed throughout the biogeography and inhabit a variety of environments, including freshwater, saltwater and terrestrial environments. The genus Proales includes 41 species that are characterized by various morphological features. In Korea, the presence of Proalidae has been documented with 5 species: Bryceella perpusilla (Wilts, Martínez Arbizu & Ahlrichs, 2010), B. stylata (Milne, 1886), B. tenella (Bryce, 1897), Proales fallaciosa (Wulfert, 1937) and Proalinopsis caudatus (Collins, 1872). The habitus of P. amplus has some similarities w

Lilliput brittlegill (Russula lilliputia) and Pakaraimaea brittlegill (Russula pakaraimaeae)

NEWS - Two new species of Russula from Guyana with small basidiomata: lilliput brittlegill ( Russula lilliputia ) and Pakaraimaea brittlegill ( Russula pakaraimaeae ) found in association with the hosts Dicymbe altsonii and Pakaraimaea dipterocarpacea were identified as new species based on a combined approach of morphological characterization and molecular analysis. Ectomycorrhizal fungi (ECM) have historically been considered underrepresented in Neotropical forests, however, pockets of forest occupying the white sands region of the central Guiana Shield of Guyana are dominated by leguminous ECM trees that support an extraordinary diversity of fungi. Russulaceae comprise the largest number of species in this region. The discovery of two new species of Russula expands our understanding of fungal diversity and the genus Russula in particular, along with the biogeography and ecosystem dynamics of often undercollected tropical forests. R. lilliputia has small basidiomata and a fruiting
