Four New Species of Tetrigidae (Orthoptera)

Four new species of Tetrigidae (Orthoptera) from Anhui province, China, are described, namely Paragavialidium anhuiensis n. sp. of Scelimeninae, Bolivaritettix jinzhaiensis n. sp. of Metrodorinae, Bannatettix anhuiensis n. sp., and Formosatettix albomaculatus n. sp. of Tetriginae.     

A new species of the Pantepui endemic genus Riolama (Squamata: Gymnophthalmidae) from the summit of Murisipán‐tepui,with the erection of a new gymnophthalmid subfamily

The gymnophthalmid lizard R iolama inopinata sp. nov. is described from the summit of Murisipán‐tepui, Bolívar State, Venezuela. The new species is characterized by its small size, slender body, short neck, chestnut brown dorsum with two conspicuous orange‐brown dorsolateral stripes, 30 or 31 mid‐dorsal scales, and 18 or 19 ventral scales in transverse rows, 28 scales around midbody, seven supralabials, five or six infralabials, subdigital lamellae divided in small granular scales, ten or 11 small femoral pores in males, dorsal surface of tongue covered with oblique chevron‐shaped plicae interrupted by a small midsection of imbricate scale‐like papillae, and a small weakly bilobed hemipenis having the sulcus spermaticus flanked by an extensive nude area on each side, and the asulcate and lateral faces of the organ with short series of small roughly equidistant, feebly developed flounces, each bearing a single medial hook‐shaped spine. Molecular phylogenetic analyses based on one nuclear and two mitochondrial DNA genes confirm the allocation of the new species to the genus Riolama, but do not support the assignation of Riolama to the subfamily Cercosaurinae as previously suggested based on overall morphological similarities, nor to any other known subfamily of the Gymnophthalmidae. Therefore, a new subfamily, the Riolaminae, is proposed to accommodate the genus. © 2015 The Linnean Society of London     

Taxonomic Study of Korean Chrysochraontini (Orthoptera: Acrididae: Gomphocerinae)

Five species of Korean Chrysochraontini are recognized through the taxonomic investigation. Among them Chrysochraon dispar major Uvarov, 1925 is newly recorded from North Korea, and Euthystira pavlovskii Bey‐Bienko, 1954 is synonymized under Mongolotettix japonicus (Bolívar, 1898). A key is provided, and morphological variations of M. japonicus are discussed.     

应用COⅠ基因序列探讨中国蚱总科四亚科部分物种的系统发生关系(英文)

通过测定蚱科26种蚱的线粒体DNA细胞色素c氧化酶Ⅰ基因的部分序列,分析了蚱亚科、短翼蚱亚科、刺翼蚱亚科及股沟蚱亚科部分物种的系统发育关系。以蜢总科的Vandiemenella viatica和Proriferasp.作为外群,构建了MP树和Bayes树。在获得的598bp的序列中,有289个变异位点,253个简约信息位点; A、T、G和C的碱基平均含量分别为31.6% ,32.7% ,19.5% ,16.2% , A+T含量高于G+C含量。分子系统树显示:蚱亚科尖顶蚱属和该亚科其他属的亲缘关系较远,而与短翼蚱亚科的狭顶蚱属有较近的亲缘关系。尖顶蚱属的广西尖顶蚱聚在短翼蚱科内,与该亚科的尖翅狭顶蚱形成姐妹群且支持两者关系的置信度很高,广西尖顶蚱不应属于蚱亚科尖顶蚱属。龙滩柯蚱与蚱属的桂南蚱形成姐妹关系,而庭蚱属的细庭蚱聚在柯蚱属中,且蚱亚科柯蚱属的防城柯蚱与刺翼蚱亚科的二刺羊角蚱形成姐妹关系,因此柯蚱属不是单系群,作为一个单独的属是可疑的;蚱属不是单系群,日本蚱也不是蚱属中的原始物种,锯齿股蚱和粗体蚱碱基序列完全相同,再次证明二者为同一物种。

Phylogeny and taxonomic revision of Heteropachylinae (Opiliones: Laniatores: Gonyleptidae)

Heteropachylinae Kury, 1994 is currently considered an early lineage of Gonyleptidae Sundevall, 1833 and includes small harvestmen that occur in the Atlantic Forests, mainly in the Northeast Region of Brazil. The species of Heteropachylinae were spread in different subfamilies until the establishment of the group. As a result of that, until now there were no comparative works on the subfamily in the literature. In this study, the first systematic review for Heteropachylinae was carried out and the first phylogenetic hypothesis for their taxa is proposed, by means of a cladistic approach. A total of 102 morphological characters was coded for 21 terminal taxa: 11 species of Heteropachylinae, two species from the genus Mangaratiba Mello‐Leitão, 1940 (considered as Heteropachylinae before this paper), seven other gonyleptids, and one cosmetid. The data were analysed using heuristic search algorithms, resulting in one most parsimonious tree (280 steps, consistency index = 0.47, retention index = 0.63). A parsimony analysis under implied weights was also performed, resulting in three trees. According to the results, Heteropachylinae is a monophyletic and well‐supported group if Mangaratiba is excluded. This genus should be returned to where it was originally described – Pachylinae. The subfamily distribution is restricted from Ceará to Espírito Santo Brazilian states. Pseudopucrolia Roewer, 1912 is considered a senior synonym of Melloa Roewer, 1930, Thaumatoleptes Roewer, 1930, and Tribunosoma Roewer, 1943. Two species of Heteropachylus Roewer, 1913, Heteropachylus ramphonotus sp. nov. and Heteropachylus gracilis sp. nov. , from Bahia and Espírito Santo Brazilian states, are newly described. Heteropachylus is considered a senior synonym of Chavesincola Soares & Soares, 1946 and Aesotrinoma H. Soares, 1977. A new genus is also described for a new species from Bahia and Espírito Santo Brazilian states, Magnispina neptunus gen. et sp. nov. Lectotypes are designated for the following species: Pseudopucrolia incerta (Mello‐Leitão, 1928) comb. nov. , Pseudopucrolia discrepans (Roewer, 1943) comb.nov. , Pseudopucrolia rugosa (Roewer, 1930) comb. nov. , Heteropachylus inexpectabilis (Soares & Soares, 1946) comb. nov. and Heteropachylus spiniger Roewer, 1913. © 2011 The Linnean Society of London, Zoological Journal of the Linnean Society, 2011, 163 , 437–483.     

A cladistic analysis of the Stygnicranainae Roewer, 1913 (Arachnida,Opiliones, Cranaidae) – where do longipalp cranaids belong?

A character survey compiling the morphological information of the subfamily Stygnicranainae was carried out. Two new species of Stygnicranaus Roewer, 1913 are described from Colombia and the new genus Agathocranaus is described from Ecuador. All known species of the subfamily are included in a matrix of 46 morphological characters. Parsimony analysis under implied weights recovered a monophyletic Stygnicranainae including Tryferos Roewer, 1931 plus Stygnicranaus and Agathocranaus. However, the usage of the four subfamilies of Cranaidae as currently defined is abandoned because the two largest subfamilies of Cranaidae – Cranainae and Prostygninae – represent paraphyletic groups (grades), whereas Heterocranainae is a superfluous subfamily, including only the genus Heterocranaus Roewer, 1913. © 2009 The Linnean Society of London, Zoological Journal of the Linnean Society, 2009, 157 , 470–494.
