Junior Synonym

There are 22 genera and more than 100 described species of Ectrichodiinae in the New World (Gil-Santana et al. 2015). Intraspecific variation in coloration and body size have been recorded in several species of the subfamily. These characteristics can occur in the same population or can suggest geographic variation of the same species (Wygodzinsky 1951, Dougherty 1995, Gil-Santana & Baena 2009, Gil-Santana et al. 2013). Sexual dimorphism is also common: females are almost always more or less larger than males, frequently have thicker fore femora and smaller eyes and ocelli (Dougherty 1995).

AbstractWe quantified sexual dimorphism and allometric changes in the lung morphology of 160 juvenile and adult specimens of prairie rattlesnake, Crotalus viridis viridis, from a single population. In virtually all lung components, those of males are located more posteriorly than are those of females of the same body size. Males display a longer vascular component than females but there is no sexual dimorphism in size of the avascular component. Thus, males generally have longer lungs than do females at all body sizes. With increasing body size, the lung components are found more anteriorly, relative length of the vascular lung decreases, and relative length of the avascular lung increases in both sexes. However, total lung length increases isometrically with body size. These sexual and allometric differences suggest that intraspecific variation should be taken into account when lung size characters are used in snake systematic studies.

Polymorphism and sexual dimorphism are common in insects. Thrips have been reported to exhibit intraspecific variation in body size, color and wing length (Mound 2005), also sexual dimorphism in abdominal pore plates, antennal sensoria and fore leg armature (Tyagi et al. 2008). Chilothrips Hood is a small genus that currently comprises seven species (ThripsWiki 2017), three from USA, one from Japan, and three from China. No male has been reported in the three species from China, C. strobilus, C. jiuxiensis and C. hangzhouensis (Hu & Feng 2015), and C. strobilus was described on three female specimens from cones of Pinus in Liaoning Province, northeastern China (Tong & Zhang, 1994). Recently, we have surveyed different parts of northeastern China and collected many male individuals of C. strobilus. We have observed that this species shows sexual dimorphism in mouth cone length, and remarkable variation in form of abdominal segment X among females.

AbstractHermann's tortoise (Testudo hermanni) is widely distributed in western and southern Europe. Most populations in the western part of the distribution range (e.g. Spain, France, Italy) are severely reduced, and relatively well studied, whilst the species is still abundant in eastern areas (i.e. the Balkans). However, essential biological information (e.g. main morphological, ecological, and behavioural characteristics) for the Balkans are still extremely limited. As reptiles exhibit strong geographic variation in most morphological, as well as life history traits, gathering data from distant areas is important. We present data from two populations of T. hermanni in Serbia, focusing on sexual dimorphism in body size and body shape. We found that almost all of the 43 morphological traits analysed were significantly different between sexes and that sexual size and sexual shape dimorphisms were not expressed in similar ways. Notably, sexual size dimorphism (SSD) was more pronounced than sexual shape dimorphism (SShD). Our analyses suggested that SShD is more stable than SSD, and that the scale of the focus (i.e. whole body proportions versus morphological details) is a key factor to test this notion. When general measurements were considered, the expected consistency of SShD between populations was verified; nevertheless, when more specific morphological attributes were considered, substantial variations were observed. These results provide a baseline for comparisons between populations to further examine geographic variation of sexual dimorphism.

Specific Variation

AbstractUnderstanding inter-specific variation in social systems is a major goal of behavioural ecology. Previous comparative studies of mammalian social organisation produced inconsistent results, possibly because they ignored intra-specific variation in social organisation (IVSO). The Artiodactyla have been the focus of many comparative studies as they occupy a wide diversity of habitats and exhibit large variation in life history patterns as well as other potential correlates of social organisation. Here we present the first systematic data on IVSO among Artiodactyla, infer their ancestral social organisation, and test whether habitat, sexual dimorphism, seasonal breeding, and body size predict inter- and intraspecific variation in social organisation. We found data on social organisation for 110 of 226 artiodactyl species, of which 74.5% showed IVSO. Using Bayesian phylogenetic multilevel models, the ancestral artiodactyl population was predicted to have a variable social organisation with significantly higher probability (0.77, 95% CI 0.29-1.00) than any non-variable form (i.e. solitary, pair-living, group-living). Greater sexual dimorphism and smaller body size both predicted more IVSO; smaller body size also predicted a higher likelihood of pair-living. Our results challenge the long-held assumption that ancestral Artiodactyla were pair-living and strongly imply that taking IVSO into account is crucial for understanding mammalian social evolution.

Pelage Color

Abstract Mammalian pelage color can vary among individuals of many species, although this intraspecific variation is often overlooked by researchers, perhaps because of its sometimes subtle nature and difficulty in assessing it quantitatively. Thus, such variation is rarely studied in mammals, and this is especially true within the order Chiroptera, where there has been very little empirical research. We examined museum specimens of red bats (Lasiurus borealis, family Vespertilionidae) from Georgia, USA, to determine the extent of sexual dimorphism in pelage color and to explore possible associations between body size and pelage color. We photographed 54 specimens under uniform lighting, and used an image analysis program to measure pelage hue on the uropatagium region, which is fully furred in members of the genus Lasiurus. Statistical analyses of pelage hue scores showed males had significantly redder pelage than females when considered alone, but when examined together with effects of body size and collection year, sex was not significant, and collection year and body size were. More recent specimens tended to be less red than older specimens, which might indicate a wearing of the buffy tips of hairs from older specimens, and smaller bats of both sexes tended to be more red. These interesting findings are encouraging and we suggest that future explorations into intraspecific variation in pelage color of bats using this or similar approaches are warranted to clarify the significance of the patterns. This study also demonstrated that care must be taken in analyses of mammalian pelage color from older museum skins, or at least that researchers must take into account the age of the specimens.

New Synonymy

The hyperdiverse ant genus Pheidole has its center of diversity in the New World, where over 600 species occur. In spite of recent revisonary work (Wilson 2003) new species continue to be discovered and understanding of geographic variation of named species continues to improve. In this report new species and taxonomic changes are proposed for the Central American fauna. The following new species are described: P. bigote, P. branstetteri, P. carinote, P. debilis, P. eowilsoni, P. epiphyta, P. fossimandibula, P. gymnoceras, P. janzeni, P. karolmorae, P. karolsetosa, P. lagunculinoda, P. leoncortesi, P. mesomontana, P. pararugiceps, P. phanigaster, P. picobarva, P. purpurea, P. rhinomontana, P. sebofila, P. sparsisculpta, P. synanthropica, and P. tenuicephala. The following new synonymy is proposed, with the senior synonym listed first and the junior synonym(s) in parentheses: P. angusticeps Wilson (= P. gradifera Wilson); P. arachnion Wilson (= P. iracunda Wilson); P. bilimeki Mayr (=P. rectiluma Wilson); P. boliviana Wilson (= P. mincana Wilson, P. scitula Wilson); P. boltoni Wilson (= P. humida Wilson); P. deceptrix Forel (=P. chiapasana Wilson, P. variceps Wilson); P. erratilis Wilson (= P. petersoni Wilson); P. exarata Emery (= P. grantae Forel); P. harrisonfordi Wilson (= P. prolixa Wilson, P. ruida Wilson, P. tenebra Wilson); P. laselva Wilson (=P. ebenina Wilson); P. mooreorum Wilson (= P. fariasana Wilson); P. nebulosa Wilson (= P. scabriventris Wilson); P. nitidicollis Emery (= P. sagana Wheeler); P. perpusilla Emery (= P. breviscapa Forel); P. pubiventris Mayr (= P. variegata Emery, P. indistincta Forel); P. radoszkowskii Mayr (= P. medialis Wilson); P. sculptior Forel (= P. tayrona Wilson); P. susannae Forel (= P. obscurior Forel and its synonym P. partita Mayr); P. texticeps Wilson (= P. perdiligens Wilson); P. vorax (Fabricius) (= P. cephalica F. Smith and its synonyms P. opaca Mayr, P. incrustata Forel, P. sarrita Forel, P. apterostigmoides Weber); P. walkeri Mann (= P. arietans Wilson, P. glyphoderma Wilson, P. triumbonata Wilson). Pheidole innupta Menozzi is removed from synonymy under P. alfaroi and revalidated.
