The carnivorous plant Pinguicula filifolia occurs in western Cuba and shows a restricted distribution due to habitat specificity associated with poor wet soils. Its populations are distributed mainly in south Pinar del Río (Cuba) and in Isla de la Juventud. Plants from one isolated location in NW Pinar del Río shows morphological differences with respect to the rest of the known populations observed in nature. Subsequent detailed morphological analysis of specimens led to the description of Pinguicula filifolia subsp. alba as a new subspecies. It differs from the typical subspecies in several reproductive traits involving flower, fruit and seed characters and is so far known only from the type locality.

Introduction: The relationships within the Pyrrhura species complex are partly unresolved. In this study, a comprehensive phylogenetic analysis of the Pyrrhura picta-leucotis complex was carried out, covering all species except P. subandina. Material and Methods: We made a morphological analysis of 745 preserved specimens of all the taxa in different museums. Nucleotide sequences of the mitochondrial cytochrome gene were generated and used to reconstruct a molecular phylogeny of Pyrrhura. Results and Discussion: Our results show that the complex is divided into 6 main groups comprising 15 species. P. dilutissima, regarded up to now as a subspecies of P. peruviana, acquires species status and three new subspecies are described. We also provide evidence that P. roseifrons is a paraphyletic group, indicating the existence of probably 3 lineages of which 2 deserve species status.

The frog genus Atelognathus is currently represented by nine species distributed in Argentinean and Chilean Patagonia. It is mainly distributed in Argentina, and there are only three species in Chile (A. ceii, A. grandisonae and A. jeinimenensis). Regarding the morphological relationships among Atelognathus species, Meriggio et al. (2004) suggest that A. jeinimenensis is more related to A. salai than other species. A. salai was described from Laguna Los Gendarmes (Argentina), 90 km air line from the type locality of A. jeinimenensis. This paper presents a morphological analysis and a study of population genetics using mtDNA nucleotide data from Argentinean and Chilean localities to assess the genetic distance between A. salai and A. jenimenensis. We obtained 477 bp-long d-loop sequences from 51 Atelognathus specimens collected in four localities. According to our results, the morphological differences between A. salai and A. jeinimenensis populations are limited to size, and there are no distinctive characteristics that would separate two species, in addition to which a simple geographic pattern of genetic diversity suggests a single species of Atelognathus. Also, the populations from Chile (Cerro Castillo, RN Lago Jeinimeni and Chile Chico) and Argentina (Laguna de Los Gendarmes) have low levels of genetic divergence that may be consistent with glaciations during the Late Pleistocene. We propose Atelognathus jeinimenensis as a junior synonym of A. salai and that the Chilean populations should be assigned to A. salai.

Trunk Limb

Sequencing of the CO1 mitochondrial gene (barcoding) highlighted a possible different species in the semi-desert region of Mexico. After a detailed morphological analysis we describe Scapholeberis duranguensis n. sp. (Cladocera: Anomopoda: Daphniidae). Specimens from the type locality, El Chupadero, Durango, were compared with specimens of S. armata armata Herrick, 1882 and S. armata freyi Dumont and Pensaert, 1983 from Canada and southeastern, central and northern Mexico. The main characters that differentiate the new species are: (1) a thicker denticulate membrane with a conspicuous underlying hyaline membrane at the posterior rim of the valves, (2) fewer setae in the gnathobase of trunk limb II and (3) longer and more rectilinear ejector hooks in trunk limb I. The presence of a pore-like structure at the top of the head was also observed, however we are not certain whether this can be considered as a distinctive character, as it was not consistent in all SEM scanned organisms. The denticulate membrane, the number of setae in the gnathobase of trunk limb II and the length of the ejector hooks are characters shared with other species, however, the combination of them and in particular the structure and thickness of the double membrane at the posterior rim of the valves lead us to conclude that S. duranguensis is a species different from S. armata and from other members of this genus. The CO1 sequences of S. armata freyi and S. duranguensis n. sp. showed a mean divergence of 12.02%, thus supporting the morphological differences between them. Finally, a comparison of the CO1 sequences of Scapholeberis duranguensis n.sp. with other Scapholeberinae available in GenBank supported our results.

Two genera of Euconnus-like Stenichnini are reported to occur in Japan: Himaloconnus Franz, 1979 and Nogunius gen. n. Specimens of Himaloconnus collected on islands of the Ryukyu archipelago are identified as H. klapperichianus (Franz), previously known to inhabit Taiwan, but morphological differences were found among disjunctive populations and in consequence three new subspecies are proposed: H. klapperichianus yaeyamanus ssp. n. (Yaeyama Islands), H. klapperichianus amamianus ssp. n. (Amami-Ôshima), and H. klapperichianus okinawanus ssp. n. (Okinawa Island). Morphological structures of Japanese Himaloconnus are illustrated in detail and the diagnosis of this genus is emended, to exclude variable characters. Nogunius gen. n. is established to accommodate four species known only from Japan: N. sokani sp. n. (Okinawa Island), N. aogashimanus sp. n. (Aogashima, Izu Islands), N. kerri sp. n. (Ishigaki Island), and N. fukuuzanus sp. n. (Okinawa Island). Identification key to Japanese genera of Stenichnini is updated.

Chilean Populations

Central Chilean populations of the mouse Loxodontomys Osgood were traditionally (e.g., Pine et al., 1979) included as part of the single species recognized in the genus, L. micropus (Waterhouse). Later, Spotorno et al. (1998) considered that they belong to an up to then undescribed species for which they coined the name L. pikumche. This taxon, with type locality in “... Cajón del Río Maipo, sector Cruz de Piedra (34º 10’ S 69º 58’ W, 2.450 msnm), a 55 km S de la Central Hidroeléctrica de Las Melosas... en la Cordillera de la Región Metropolitana” is characterized by a 2n = 32 (NF = 34) and some subtle morphological differences with L. micropus (that, in turn, has a 2n = 34, NF = 36; Spotorno et al., 1998; Teta et al., 2009). More recently, Novillo et al. (2009) reported the first record of L. pikumche in the Argentinean province of Mendoza and added some putative morphological differences with L. micropus to those previously listed by Spotorno et al. (1998). As discussed by Cañon et al. (2010), the morphological characters  documented as differences by Novillo et al. (2009) have some degree of variation within populations of L. micropus s.s. (e.g., zygomatic plate morphology, lateral profile of nasals, development of posterior palate process; see Hershkovitz, 1962; Steppan, 1995) or were based on misinterpretation of some features (e.g., both specimens studied by Novillo et al. [2009] has posteriorly divergent toothrows, and not only that of micropus). Indeed, the distinction of L. pikumche was recently put in interdict by Cañon et al. (2010) on the base of molecular and morphological evidence. These authors remarked that several putative diagnostic characters (e.g., molar root numbers, incisor orientation, shape of upper incisor dentine fissure) vary within and among populations of L. micropus s.s. Further, Cañon et al. (2010) suggested that L. pikumche may be a junior synomyn of L. m. alsus (Thomas, 1919).

Morphological Differences

Proper processes of hematopoiesis have a major impact on the results of blood morphological analyses in healthy animals. The aim of this study was to evaluate bone marrow smears of female fallow deer kept in captivity and comparing them to morphological analysis of peripheral blood. To achieve the aim of this study bone marrow was collected from 10 nonpregnant, 2-year-old female fallow deer. Smears stained by the May-Grünwald Giemsa method were analyzed. Bone marrow samples were collected using a biopsy needle from the 3rd – 4th rib in the sternal region into test tubes without coagulant. Whole blood for hematological analysis was sampled from the external jugular vein into 2 ml test tubes containing K2EDTA. The results of the research indicate significant morphological differences of white blood cells line and red blood cells line of fallow deer in comparison to other ruminants. Proerythroblasts of fallow deer appear to have a higher number of nuclei that stain more clearly in the MGG method. In red the blood cells line a high percentage of polychromatic erythroblasts (17.2%) and basophilic erythroblasts (8.19%) was noted. In granulocyte line only 0.97% of myeloblasts was observed in bone marrow smears. The percentage of segmented and band granulocytes was determined at 6.86% and 2.27% consequently. In the lymphoblastic line of fallow deer a low percentage of plazmocytes was observed (1.16%). In the platelets line the percentage of megakaryoblasts (5.85%) was lower than megakaryocytes (7.9%). This report is the first study concerning hematopoiesis in female fallow deer.

Guilan Province

This article, in line with “The National Project of the Dialectology”, aims to provide a linguistic atlas in the East of Guilan province. Due to the large number of speakers in the southern edge of the Caspian Sea and many differences between dialects and accents, this area has great importance linguistically and providing the linguistic atlas in representation and introduction of dialects in this land can be an important achievement to access the indigenous, cultural, social and historical studies among linguistics and persons who are interested in culture. In order to achieve this principal issue, there has been investigated the morphological differences and similarities (lexical - inflectional) of language varieties in the East of Guilan province with the standard Persian- even more than phonetic and syntactic analysis- and they can have the principal role in providing the linguistic atlas. So in this article, through presenting the morphological evidences (lexical - inflectional) and comparing them with standard Persian, there has been marked a dialect with different accents- the Guilaki dialect from the East of Guilan province and it has been depicted for linguistic atlas. The study was conducted by library and field method and by collecting data from a questionnaire consisting of 100 words and sampling from 20 villages in the East of Guilan province- from Astaneh Ashrafieh to the end of the eastern border of Guilan province (Chaboksar). The data obtained by each village has been considered in the tables related to each word and has been moved on the map of region after comparing with the standard Persian and finally the linguistic atlas has been made. To achieve genuine accents, the speakers of middle-aged who spent much of their life in the area have been helped and villages have been considered with more phonetic differences in accent.
