安徽省兽类一属和种新纪录——侯氏猬

Two specimens of Mesechinus hughi were collected from Pingshan, Yi County, Huangshan (29°56'23"N, 117°58'48"E) and Xikou, Xuanzhou, Xuancheng (30°34'42"N, 118°41'47"E) in Anhui Province, in July and September 2018, respectively. Ears of the two specimens are similar, in length, to the surrounding spines. The two specimens have few wholly white spines, and most spines (>95%) have four sections; white constituting the basal two-thirds, followed by a black ring, narrow light ring, and black tip. These characters are similar to those of the specimens from the type locality (Baoji, Shaanxi Province). The P-distance of Cyt b between the population in Anhui and that of Shaanxi is from 4.9% to 5.3%, and maximum likelihood phylogenetic analyses support the two populations as monophyletic (BS = 95%). This was the first recorded distribution of Mesechinus in Anhui Province and Mesechinus hughi south of the Changjiang River.     

Taxonomic revision of shrews of the genus Crociduras from the Sunda Shelf and Sulawesi with description of two new species (Mammalia: Soricidae)

The skulls of 387 shrews of the genus Crocidura sampled in peninsular Malaysia, Sumatra, Borneo, Java and Sulawesi were submitted to principal component and stepwise discriminant analyses. These analyses helped to delineate morphological taxa in this species-rich genus of mammals. Most morphologic groups could be attributed to described species, except one taxon from Sumatra and one from Sulawesi, which are described and named as new. Most of the 21 species recognized in this paper are endemic to one major island. Although Sulawesi has never been connected to the mainland, it supports at least six species, followed by Sumatra (5–6 species), Java and the Malay Peninsula (4 spp) and Borneo (3 spp). C. monticola is apparently the only widespread species whose distribution range covers the entire Malay Archipelago except the Philippines and Sulawesi. In contrast, the continental C. fuliginosa enters only marginally into the Sunda Shelf: its southernmost record is on the Malay Peninsula. This interpretation is completely different from the classical view that C. fuliginosa is a cosmopolitan species occupying the whole of Southeast Asia. Identification keys, tables of measurements and discriminant functions provided in this work may aid in identification of the various species and subspecies of Crocidura living in the Malaya Archipelago.     

Taxonomic study of the genus Deltonotus Hancock (Orthoptera: Cladonotidae) with description of a new species

The genus Deltonotus Hancock, 1904 was reviewed, including one new species, D. wuzhishanensis sp. nov. A key to species of the genus Deltonotus Hancock, 1904 is given. The type specimens are deposited in the Institute of Zoology, Shaanxi Normal University.     

Taxonomic revision of the South American fish genus Chalceus Cuvier (Teleostei: Ostariophysi: Characiformes) with the description of three new species

The Neotropical characid fishes of the genus Chalceus Cuvier, 1817, are reviewed. In total, five species are recognized (including three new species). Chalceus epakros sp. nov. is the most widespread geographically, occurring in many rivers of the Amazon basin, the Río Orinoco and in the Essequibo River drainage in Guyana. Chalceus guaporensis sp. nov. is restricted to the upper Rio Madeira, Rio Guaporé and Río Madre de Dios, of Brazil, Bolivia and Peru, respectively. Chalceus spilogyros sp. nov. occurs only in the Rio Trombetas, lower Rio Tapajós and lower Rio Madeira drainages. Chalceus macrolepidotus Cuvier occurs in the Rio Negro drainage, middle and lower Río Orinoco basin and in the rivers of the Atlantic slopes of the Guianas, and Chalceus erythrurus Cope in the Rio Amazonas and Rio Solimões to Río Ucayali drainage in Peru. Chalceus ararapeera Cuvier & Valenciennes and Creagrutus pellegrini Puyo are considered synonyms of C. macrolepidotus , and Pellegrinina heterolepis Fowler is placed into the synonymy of C. erythrurus . Characters pertaining to the monophyly of Chalceus are discussed and a key to species is presented.  © 2004 The Linnean Society of London, Zoological Journal of the Linnean Society , 2004, 140 , 103−135.     

Taxonomic revision of the genus Gynecaptera Skorikov, 1935 from Egypt,with description of a new species (Hymenoptera: Bradynobaenidae,Apterogyninae)

The genus Gynecaptera Skorikov (Bradynobaenidae: Apterogyninae) is revised from Egypt, based on specimens collected from the Sinai Peninsula and those deposited in Egyptian insect collections as well as recorded data from the literature. Three species were previously recorded from Egypt, G. alexandri (Invrea), G. alfierii (Invrea) and G. trimaculata (Skorikov). Gynecaptera sinaitica sp. n. is described here. An illustrated key and a faunistic list comprising all Gynecaptera species recorded from Egypt are also given.

Taxonomic revision of the olingos (Bassaricyon), with description of a new species,the Olinguito

We present the first comprehensive taxonomic revision and review the biology of the olingos, the endemic Neotropical procyonid genus Bassaricyon, based on most specimens available in museums, and with data derived from anatomy, morphometrics, mitochondrial and nuclear DNA, field observations, and geographic range modeling. Species of Bassaricyon are primarily forest-living, arboreal, nocturnal, frugivorous, and solitary, and have one young at a time. We demonstrate that four olingo species can be recognized, including a Central American species (Bassaricyon gabbii), lowland species with eastern, cis-Andean (Bassaricyon alleni) and western, trans-Andean (Bassaricyon medius) distributions, and a species endemic to cloud forests in the Andes. The oldest evolutionary divergence in the genus is between this last species, endemic to the Andes of Colombia and Ecuador, and all other species, which occur in lower elevation habitats. Surprisingly, this Andean endemic species, which we call the Olinguito, has never been previously described; it represents a new species in the order Carnivora and is the smallest living member of the family Procyonidae. We report on the biology of this new species based on information from museum specimens, niche modeling, and fieldwork in western Ecuador, and describe four Olinguito subspecies based on morphological distinctions across different regions of the Northern Andes.

Taxonomic revision of the marbled skink (Cyclodina oliveri,Reptilia: Scincidae) species complex,with a description of a new species

Abstract

We have completed a taxonomic revision of the New Zealand marbled skink (Cyclodina oliveri) species complex. Morphological analyses and mitochondrial sequence data (ND2, ND4, Cytochrome b; Total 1933 bp) are used to describe a new taxon (commonly known as the “Mokohinau” skink) and redefine C. oliveri. The morphological and molecular data indicate that C. oliveri is distributed on the Poor Knights Islands, Mercury Islands and Aldermen Islands. The new species is restricted to the Mokohinau Islands, Hen and Chickens group, Little Barrier Island and Great Barrier Island. Our data demonstrate that there is no support for the separation of the Poor Knights Islands population of C. oliveri from those on the Mercury Islands and Aldermen Islands. The genetic data indicate that C. whitakeri is part of the C. oliveri species group. Divergence time estimates indicate that the C. oliveri species complex diverged during the late‐Miocene, with further divergences among island groups in C. oliveri including the origin of the new taxon during the late‐Pliocene and mid‐Pleistocene. We present a diagnostic key for Cyclodina.     

A revision of the genus Lomaantha, with the description of a new species

Lomaantha phragmitis sp. nov. is described and illustrated from a specimen collected on dead culms of Phragmites communis in southern China. The fungus differs from other described Lomaantha species in its conidiophores, conidiogenous cells and conidial appendages. Conidial morphology and presence or absence of percurrent proliferation of conidiogenous cells are the main characters distinguishing species within this genus. We provided a key and synoptic table of morphological characters of all three Lomaantha species.
