Congruent phylogenetic and fossil signatures of mammalian diversification dynamics driven by Tertiary abiotic change

Computational methods for estimating diversification rates from extant species phylogenetic trees have become abundant in evolutionary research. However, little evidence exists about how their outcome compares to a complementary and direct source of information: the fossil record. Furthermore, there is virtually no direct test for the congruence of evolutionary rates based on these two sources. This task is only achievable in clades with both a well‐known fossil record and a complete phylogenetic tree. Here, we compare the evolutionary rates of ruminant mammals as estimated from their vast paleontological record—over 1200 species spanning 50 myr—and their living‐species phylogeny. Significantly, our results revealed that the ruminant's fossil record and phylogeny reflect congruent evolutionary processes. The concordance is especially strong for the last 25 myr, when living groups became a dominant part of ruminant diversity. We found empirical support for previous hypotheses based on simulations and neontological data: The pattern captured by the tree depends on how clade specific the processes are and which clades are involved. Also, we report fossil evidence for a postradiation speciation slowdown coupled with constant, moderate extinction in the Miocene. The recent deceleration in phylogenetic rates is connected to rapid extinction triggered by recent climatic fluctuations.     

First record of Stigmatijanus Wei (Hymenoptera: Cephidae)from South Korea with description of a new species

The genus Stigmatijanus Wei, 2007 is recorded from Korea for the first time. A diagnosis of the genus is briefly discussed. A new species, Stigmatijanus koreanus sp. nov., is described from Mt. Homyeong, Gyeonggi-do, South Korea. A key to the three species of the genus is provided.

The genus Scapheremaeus (Acari,Oribatida, Cymbaeremaeidae) in the oribatid mite fauna of New Zealand,with description of two new species

Two new species of oribatid mites of the genus Scapheremaeus (Oribatida, Cymbaeremaeidae), Scapheremaeus gibbus sp. n. and Scapheremaeus luxtoni sp. n., are described from New Zealand. Scapheremaeus gibbus sp. n. is morphologically most similar to Scapheremaeus humeratus Balogh & Mahunka, 1967, but differs from the latter by the number of notogastral, genital and adanal setae, morphology of bothridial setae, position of adanal lyrifissures and absence of humeral processes. Scapheremaeus luxtoni sp. n. is morphologically most similar to Scapheremaeus yamashitai Aoki, 1970, but differs from the latter by the morphology of notogastral and rostral setae, morphology of leg solenidia φ₂ and development of humeral processes. The species Scapheremaeus zephyrus Colloff, 2010 is recorded for the first time in New Zealand. An identification key to the known New Zealand species of Scapheremaeus is provided.     

Taxonomic studies on the ant genus Ponera Latreille, 1804 (Hymenoptera,Formicidae), with the description of a new species from India

Four species of the ant genus Ponera Latreille, 1804, are recorded from India. The present study reports one new species Ponera sikkimensis sp. n., a divergent population of Ponera indica Bharti & Wachkoo, 2012 and one new record, Ponera paedericera Zhou, 2001 from India. An identification key and distributions for the four known Indian species of Ponera based on the worker caste are provided.     

Contributions to the knowledge of oribatid mites (Acari,Oribatida) of Indonesia. 3. The genus Galumna (Galumnidae) with description of a new subgenus and seven new species

Seven new species of oribatid mites of the genus Galumna are described from litter and soil materials of Sumatra, Indonesia. A new subgenus, Galumna (Atypicogalumna) subgen. n., is proposed; it differs from all galumnid genera and subgenera by the simultaneous presence of porose areas and sacculi on the notogaster (vs. either porose areas or sacculi present). Galumna (Galumna) calva Starý, 1997 is recorded for the first time in the Oriental region, and Galumna (Galumna) sabahna Mahunka, 1995 is recorded for the first time in the Indonesian fauna.     

A review of the omicrine genera Omicrogiton,Mircogioton and Peratogonus of China (Coleoptera,Hydrophilidae, Sphaeridiinae)

The Chinese species of the genera Omicrogiton Orchymont, 1919, Peratogonus Sharp, 1884 and Mircogioton Orchymont, 1937 are reviewed, diagnosed and keyed. Mircogioton and Omicrogiton are reported for the first time from China, Peratogonus for the first time for mainland China. Five species are recognized: Omicrogiton coomani Balfour-Browne, 1939 (Guangdong, Hongkong), Omicrogiton hainanensis sp. n. (Hainan), Omicrogiton roberti sp. n. (Hainan), Mircogioton coomani Orchymont, 1937 (Yunnan), and Peratogonus reversus Sharp, 1884 (Guangdong, Jiangxi, Taiwan). Lectotype of Omicrogiton coomani is designated. Mircogioton cognitus (Malcolm, 1981), syn. n. is considered a junior subjective synonym of Mircogioton coomani Orchymont, 1939. Species of Mircogioton and Omicrogiton inhabit decaying banana trunks, whereas Peratogonus reversus was always collected from moist forest leaf litter.

贵州蕨类植物一新记录属——乌木蕨属Blechnidium Moore

本文报道了贵州蕨类植物一新记录属——乌木蕨属Blechnidium Moore,该属为乌毛蕨科Blechnaceae一单种属,仅乌木蕨Blechnidium melanopus（Hook.）Moore一种。此物种分布区狭窄,数量有限,在贵州的发现对研究其地理与区系很有意义。
