Molecular and Morphological Evidence for the Occurrence of Two New Species of Invasive Slugs in Kentucky, Arion intermedius Normand and Arion hortensis Férussac (Arionidae: Stylommatophora)

A molecular phylogeny of the western Palearctic weevil genus Kyklioacalles Stüben, 1999 is presented, combining two mitochondrial genes (CO1 and 16S) in a Bayesian analysis. Based on molecular data, the validity of the subspecies Kyklioacalles punctaticollis punctaticollis (Lucas, 1849) and Kyklioacalles punctaticollis meteoricus (Meyer, 1909) is discussed and the morphological differentiation of the endophalli and known distributions of both subspecies are verified. Glaberacalles subg. n. (formerly Kyklioacalles punctaticollis-group) and two new species are described, Kyklioacalles atlasicus sp.n. from Morocco and Kyklioacalles plantapilosus sp.n. from Spain. Kyklioacalles berberi (Stüben, 2005), comb. n. and Kyklioacalles olcesei (Tournier, 1873) comb. n. are transferred from Acalles Schoenherr. The molecular results further advocate a transfer of Onyxacalles pyrenaeus (Boheman, 1844) to Kyklioacalles; however this is not supported by morphological evidence. Kyklioacalles almadensis Stüben, 2004 syn. n. (Spain) is synonymized with Kyklioacalles bupleuri Stüben, 2004 (Tunisia). A catalogue of all 40 (sub-)species of Kyklioacalles is given and a key of the species of the subgenus Glaberacalles is presented.

Crotalus Durissus

Members of the Crotalus durissus species complex are widely distributed from Mexico to Argentina in areas with mainly seasonally dry tropical deciduous forest. Although four species (C. culminatus, C. durissus, C. simus and C. tzabcan) are currently recognized, species limits remain to be tested. Previous genetic studies suggest that C. durissus and C. simus may be paraphyletic and that at least one cryptic species may be present. We analyzed 2596 bp of DNA sequence data from three mitochondrial and one nuclear gene to infer phylogenetic relationships in the Neotropical rattlesnakes. We also examined museum and wild specimens as well as captive animals to analyze morphological characters. Our results suggest that the current taxonomy of the Crotalus durissus species complex does not reflect evolutionary history. We found strong support for five independent lineages within Crotalus simus (sensu lato), with genetic and morphological evidence for three previously recognized taxa and two new species, as well as three major lineages within C. durissus that each represent species hypothesis to be tested with additional evidence. We also found support to retain C. totonacus in the Crotalus molossus species complex. We suggest conservative taxonomic changes to the complex and related species, but more evidence is needed (e.g., morphology, ecology and venom composition) to clarify relationships among species.

Insect Fossils

A radiometrically dated Pliocene fossil locality in western Alaska contains specimens representing two new species of insects: Micropeplus hoogendorni n. sp. and Micropeplus hopkinsi n. sp. (Coleoptera: Staphylinidae, Micropeplinae). Fossils of the extant Micropeplinae species Kalissus nitidus LeConte and Micropeplus tesserula Curtis occur with the fossils of the newly described species. Other insect fossils and plant fossils from the locality suggest that M. hoogendorni and M. hopkinsi lived in a coniferous forest somewhat similar to those in present-day British Columbia or Southeastern Alaska.The holotype and paratypes of Micropeplus hopkinsi provide morphological evidence for the evolutionary sequence of elylral puncture development in the genus Micropeplus. This and other information is used to construct a provisional phylogeny for the subfamily Micropeplinae. The probable derivation of the species groups of Micropeplus is discussed.

Two new wood-inhabiting fungi, Mycorrhaphium subadustumsp. nov. and Trullella conifericolasp. nov., are proposed and described from Asia based on ITS, nrLSU and tef1 molecular phylogeny and morphological characteristics. Mycorrhaphium subadustum is characterized by a stipitate basidiocarp, velutinate pileal surface concentrically zoned, hydnoid hymenophore, a dimitic hyphal system in spine trama and monomitic in context, absence of gloeocystidia, presence of cystidioles and the non-amyloid, cylindrical to ellipsoid basidiospores. Trullella conifericola is characterized by a laterally stipitate basidiocarp with flabelliform to semicircular pileus, hirtellous pileal surface with appressed coarse hair and concentrically zoned and sulcate, tiny pores (10–12 per mm), a dimitic hyphal system, absence of any type of cystidia, short clavate basidia and thin-walled, smooth, cylindrical to allantoid basidiospores. Phylogenetic analyses based on a three-marker dataset were performed using maximum likelihood and Bayesian inference methods. The two new species formed isolated lineages with full support in Steccherinaceae. The distinguishing characters of the two new species as well as allied species are discussed, and a key to species of Mycorrhaphium is provided.

The “Probetoriformes” species group of Symmachia Hübner, [1819] proposed by Stichel (1910; 1930) is redefined based on morphological evidence, and the species herein included in the group are revised. Two new species from the Brazilian Atlantic Forest are described: S. atlantica Dias, Dolibaina & Mielke sp. nov. and S. uirassu Dolibaina, Dias & Casagrande sp. nov. Additionally, one restituted status, S. championi Godman & Salvin, 1886 stat. rest., one revalidated status, S. belti Godman & Salvin, 1886 stat. rev., and one new status, S. meyi Brévignon, 1998 stat. nov., are proposed; therefore, the “Probetoriformes” species group, as herein conceived, includes 10 of the about 60 species of the “catch-all” genus Symmachia. A neotype for Papilio probetor Stoll, 1782 and lectotypes for S. probetor form astiama Seitz, 1913, S. belti and S. championi are designated. The female of the recently described species S. divisora Dolibaina & Leite, 2012 is recognized and described for the first time. Additionally, morphologic illustrations and a dichotomous key for species of the “Probetoriformes” species group are provided.

Two species of Apiaceae are described as new to science: Zeravschania khorasanica from the Khorasan Province, eastern Iran, and Z. podlechii from the Ghor Province, central Afghanistan. Zeravschania khorasanica is related to Z. regeliana and Z. scabrifolia, but differs in rigid remains of petioles and sheaths, deeply laciniate ultimate segments of leaves, and broad-keeled ribs of mericarps. Zeravschania podlechii differs from other species of the genus in multiple stems, short internodes, dichotomous branching, and an unusual life form (сushion plant). In addition, Z. knappii is transferred to the genus Dichoropetalum on the basis of morphological evidence.

Erythrophylloporus is a lamellate genus in the family Boletaceae that has been recently described from China based on E.cinnabarinus, the only known species. Typical characters of Erythrophylloporus are reddish-orange to yellowish-red basidiomata, including lamellae, bright yellow basal mycelium and smooth, broadly ellipsoid, ellipsoid to nearly ovoid basidiospores. During our survey on diversity of Boletaceae in Thailand, several yellowish-orange to reddish- or brownish-orange lamellate boletes were collected. Based on both morphological evidence and molecular analyses of a four-gene dataset (atp6, tef1, rpb2 and cox3), they were recognised as belonging in Erythrophylloporus and different from the already known species. Two new species, E.paucicarpus and E.suthepensis are therefore introduced from Thailand with detailed descriptions and illustrations. Moreover, two previously described Phylloporus species, P.aurantiacus and P.fagicola, were also revised and recombined in Erythrophylloporus. A key to all known Erythrophylloporus species is provided.

Two New Species

Two new species of the genus Cyrtodactylus are described based on collections from Northeast India, and descriptions and diagnoses of previously described species and synonyms from the region are provided. One of the new species from lowland habitats in Tripura is medium sized, with a continuous series of precloacal pores, and is allied to C. ayeyarwadyensis from Myanmar; while the other new species from West Bengal is smaller, with both femoral and precloacal pores, and is related to C. gubernatoris from West Bengal and Sikkim. We designate a lectotype for Cyrtodactylus khasiensis and recognize the C. khasiensis synonym Gymnodactylus himalayicus as a valid species of Cyrtodactylus based on morphological evidence, and suggest the recognition of the last remaining subspecies of C. khasiensis, C. k. cayuensis, as a valid species based on geography and morphology. The stabilization of the taxa Cyrtodactylus khasiensis and C. gubernatoris with a limited subset of characters and specific distributional data, as well as the elevation of Cyrtodactylus himalayicus comb. nov. from synonymy, will allow the descriptions of many more Cyrtodactylus species from the region.
