Land snails of the family Orthalicidae from Venezuelan Guayana are revised and the following new species are described: Drymaeus (D.) rex, Plekocheilus (Eurytus) huberi, P. (E.) nebulosus, P. (E.) sophiae, and P. (E.) tepuiensis. Drymaeus (D.) griffini Haas, 1955 is now placed in the synonymy of D. (D.) extraneus (Haas, 1955). In addition, the genitalia of Plekocheilus (Eurytus) tatei Haas, 1955 are described for the first time. Plekocheilus (Eudolichotis) gibber (Oberwimmer, 1931) is now considered a member of P. (Eurytus). As a consequence, Antitragus Oberwimmer, 1931 is now regarded a junior synonym of Eurytus Albers, 1850. Of the 16 taxa treated here, 14 are endemic to the table-top mountains (‘tepuis’) of this area. A Principal Component Analysis has been used to study the biotic and abiotic factors that may influence species diversity and distributions. Habitat diversity explained 65% of the variability and was mainly influenced by plant diversity, number of forest types, elevation and slope area of the tepuis.

The land snails of the family Amphibulimidae occurring within northwestern South America are critically examined and notes on their distribution are given. The total number of taxa discussed is 61 (7 Dryptus, 54 Plekocheilus); of these, four Colombian Dryptus and 32 Plekocheilus species are included. The following new species are described: Plekocheilus (P.) bigener, P. (P.) incognitus, Plekocheilus (Eurytus) camaritagua, P. (E.) labiosus, and P. (E.) paraguas. The following nominal taxa are now synonymized: Plekocheilus (P.) speciosus (Pfeiffer, 1854) = P. (P.) plectostylus (Pfeiffer, 1848); Plekocheilus (Eurytus) couturesi Ancey, 1900 = P. (P.) glandiformis (Lea, 1838); Plekocheilus (Aeropictus) latilabris (Pfeiffer, 1855) = P. (A.) succineoides (Petit de la Saussaye, 1840); Plekocheilus (Eurytus) virgatus (Pilsbry, 1935) = P. (E.) mabillei (Crosse, 1867) = P. (E.) pulicarius (Reeve, 1848). Also, Simpulopsis fulguratus Miller, 1878 is now considered a junior subjective synonym of Simpulopsis (Eudioptus) citrinovitrea (Moricand, 1836). For the following species, precise localities are given for the first time: Dryptus stuebeli (Martens, 1885), Plekocheilus (Aeropictus) cathcartiae (Reeve, 1848), P. (E.) cardinalis (Pfeiffer, 1853), P. (Eurytus) episcopalis auriformis (Da Costa, 1904), P. (E.) episcopalis corticosus (Sowerby, 1895), and P. (E.) lynciculus (Deville & Huppé, 1850). Newly recorded for the Colombian malacofauna are the following taxa: Plekocheilus (P.) couturesi (Ancey, 1900), P. (Eurytus) piperitus (Sowerby I, 1837). The following taxa are excluded from the Colombian fauna: Dryptus funckii (Nyst, 1843), Plekocheilus (Aeropictus) veranyi (Pfeiffer, 1848), Plekocheilus (Eurytus) jimenezi (Hidalgo, 1872).

This study reviews the family Macrochelidae in Turkey, with new information about species diversity. Nothrholaspis scutivagus sp. nov., Macrocheles niksarensis sp. nov. and Holostaspella bidentata sp. nov. are described as new species from Turkey. Nothrholaspis scutivagus has a characteristic dorsal shield chaetotaxy, and post-genital platelets that are sometimes fused to the ventri-anal shield. Macrocheles niksarensis has 29 pairs of pilose dorsal shield setae and a machete-like cheliceral dorsal seta. The genus Holostaspella is recorded from Turkey for the first time, on the basis of H. bidentata. Macrocheles peniculatus and M. insignitus are reported from Turkey for the first time. Also, Macrholaspis recki and M. evansi are presented here with some notes on the Turkish specimens.

The subfamily Beridinae of the family Stratiomyidae contains about 280 known species globally, and distributed all over the biogeographical areas except polar region. In the Korean peninsula, the species diversity of this subfamily has been poorly known so far, in accordance with National species list of Korea by National Institue of Biological Resources. In this paper, the soldier fly genus Beris Latreille is reported for the first time from Korea based on following three species: B. fuscipes Meigen, B. hirotui Ôuchi, and B. tigris Lee and Suh, sp. nov. Among them, B. tigris Lee and Suh, sp. nov. was confirmed to be newly discovered. Consequently, three species within this genus have been identified from the Korean peninsula. The identification key, description, external photographs, and taxonomic notes of these Korean species are presented herein.

AbstractMorphological, life history, and distributional data are presented for North American species of the subgenus Stygomomonia (sensu stricto) Szalay, 1943. Adults of the seven previously recognized species are redescribed, and deutonymphs of five of these species are described for the first time. Two species, S. (s.s.) neomexicana Cook and S. (s.s.) occidentalis Cook are substantially revised on the basis of an examination of the types and extensive series of newly collected specimens. Three new species are described, S. (s.s.) californiensis on the basis of deutonymphs and adults, and S. (s.s.) imamurai and S. (s.s.) cooki on the basis of adults. A new diagnosis of the subgenus is proposed and discussed, the relationships of the various species are discussed, and a key to deutonymphs and adults of North American species is presented. New distributional data are presented for all species, and dispersal patterns from Pleistocene refugia are discussed.

Leaves are plant structures that express important traits of the environment where they live. Leaf description has allowed identification of plant species as well as investigation of abiotic factors effects on their development, such as gases, light, temperature, and herbivory. This study described populations of Dalbergia ecastaphyllum through leaf geometric morphometrics in Brazil. We evaluated 200 leaves from four populations. The principal component analysis (PCA) showed that the first four principal components were responsible for 97.81% of variation. The non-parametric multivariate analysis of variance (NPMANOVA) indicated significant difference between samples (p = 0.0001). The Mentel test showed no correlation between geographical distances and shape. The canonical variate analysis (CVA) indicated that the first two variables were responsible for 96.77 % of total variation, while the cross-validation test showed an average of 83.33%. D. ecastaphyllum leaves are elliptical and ovate.
