Cerapeplus siamensis gen.n., sp.n. from Thailand is described and illustrated. The new genus is characterized by filament-based lamellar secretions arising from the lateral body margin, a feature observed for the first time in Coleoptera. Possible autapomorphies for the micropeplid genera are discussed. It is concluded that Cerapeplus and Kalissus are monophyletic; Micropeplus and/Or Peplomicrus are probably polyphyletic but both genera together form a monophyletic group. A number of characters support the family status of the micropeplids recently proposed by some authors. A revised family diagnosis is provided. 相似文献

Eleven species of Omaliinae are newly recorded from New Brunswick, bringing the total number of species known from the province to 32 described species. Supporting data are presented for the New Brunswick record of Geodromicus strictus (Fauvel) reported by Majka et al. (2011). Micropeplus browni Campbell, Micropeplus laticollis Mäklin (Micropeplinae), Charyhyphus picipennis (LeConte) (Phloeocharinae), Olisthaerus substriatus (Paykull) (Olisthaerinae), Habrocerus capillaricornis (Gravenhorst), Habrocerus magnus LeConte, and Habrocerus schwarzi Horn (Habrocerinae) are also newly recorded for New Brunswick. These are the first records of the latter four subfamilies from New Brunswick. Collection and bionomic data are presented for each species and discussed. 相似文献

Two new species are described inArberella, one from Panama (Arberella lancifolia) and one from Bahia, Brazil (a. bahiensis), the latter representing a considerable extension of the known range of the genus.Cryptochloa decumbens, described from Panama, brings to ten the species recognized in this genus andRaddia angustifolia, from Bahia, increases to five the number of species in that genus. Each new species is fully illustrated and keyed. 相似文献

Sucrea, a new genus of herbaceous bambusoid grasses is based on the newly described species,S. monophylla. Also belonging to this genus is another new species,S. maculata, and the taxon originally namedOlyra sampaiana. The new genus is contrasted in a key with others of its tribe Olyreae, and a key is given to its three species. 相似文献

Two new species are added toCryptochloa,C. unispiculata from Peru andC. capillata from Brazil, the latter transferred from the genusOlyra. The genusPiresia is also augmented by two new species,P. macrophylla from Peru andP. leptophylla from Bahia, Brazil. These species represent, respectively, the westernmost and easternmost limits of distribution of the genus. 相似文献

A new genus and species from Mexico,Metastevia hintonii, is described. The genus, considered to be closely related to and derived fromStevia, differs in seven morphological features from all known species ofStevia. The reasons for recognizing the new genus are discussed in detail. 相似文献

A revision is presented, of the neotropical genusIsertia Schreber.Cassupa Humb. & Bonpl. is given a new status asIsertia sectionCassupa (Humb. & Bonpl.) B. M. Boom, based on differences in fruit type, number of locules in the ovary, and number of lobes of the stigma. A new combination is made at the species level,I. laevis (Triana) B. M. Boom, and a new species from Panama is described and illustrated,I. scorpioides B. M. Boom. Altogether, fourteen species and one variety are recognized in the genus. 相似文献

Pseudosasa xishuangbannaensis is described and illustrated as a new species of Arundinarieae (the temperate woody bamboos) from southern Yunnan, China. It belongs to Pseudosasa subg. Sinicae. The new species is characterized by glabrous culm leaf sheaths with dense setae at the base, several to many spikelets, and 5–7 glumes, and it can be distinguished from closely related species by these morphological features and molecular evidence. 相似文献

A new species of the genus Achalinus is described based on five specimens collected from the villages of Huangjialing and Fuxi, Huangshan, Anhui, China. It can be morphologically differentia ted from all the other species in Achalinus except for A. spinalis and A. werneri by the presence of a dotted black streak in the middle of the subcaudal. It can be distinguished from A. spinalis in that its two anterior temporals are in contact with eye, and A. werneri by its light brown flanks. The phylogenetic rela tionship of Achalinus was reconstructed using the mitochondrial locus of cytochrome coxidase subunit 1(CO1). The five new specimens form a monophyletic clade with strong support. The uncorrected p-dista nces between the new species and other representatives of Achalinus range from 13.6% to 21.7%. The recognition of the new species increases the number of described Achalinus species to 14. 相似文献

A new grasshopper genus and species of the subfamily Eyprepocnemidinae, Ogasawaracris gloriosus, is described from the Ogasawara Islands, oceanic islands south of Japan. This species has unique characteristics, such as an extraordinarily large body, rugose and very coarse punctation on the lateral surface of the pronotum, and very strong pronotal lateral carinae. Specimens of this new species have rarely been collected and they are known only from the Ogasawara Islands. The species may already be extinct. 相似文献

It is evident to any biologist that small-bodied species within a given higher taxon (order, class, phylum, etc.) tend to be represented by more individuals. Hence small-bodied species are generally more abundant than large-bodied species. We analyzed large herbivore species data collected in Kenyan rangelands. An index of biological diversity derived from the negative relation between animal species body size and its local abundance is proposed. We compared the new index with species abundances at landscape scale (10 × 10 km) in individual districts, as well as in the combined regional data. The results show a consistently strong positive relation between the new diversity index and species abundances. The proposed diversity index has the advantage of incorporating information on species abundances without the need for time-consuming surveys. 相似文献
