    [Fungi • 2017] Gymnosporangium przewalskii (Pucciniales, Basidiomycota) from China and Its Life Cycle

    Gymnosporangium przewalskii  Y. M. Liang & B. Cao


    Abstract

    In an investigation of rust fungi in Qinghai Province, northwestern China, the novel rust species Gymnosporangium przewalskii was identified based on morphology and phylogenetic analyses. Phylogenetic analyses using the internal transcribed spacers (ITS) and the large subunit (LSU) rRNA partial gene revealed that G. przewalskii is monophyletic and distinct from other Gymnosporangium species. The life cycle of this new taxon was clarified based on molecular data. Its spermogonial and aecial stages occurred on Sorbus koehneana, and its telial stage was found on Juniperus przewalskii.

    Padhye, Dahanukar, Sulakhe, Dandekar, Limaye & Jamdade, 2017  


    Abstract
    Sphaerotheca pashchima, a new species of burrowing frog, is described from western India. It can be diagnosed from all its congeners based on a combination of characters including interorbital width less than upper eyelid width, snout to nostril distance less than half of eye diameter, nostril nearer to snout than to eye, internarial distance greater than inter orbital distance, snout rounded, dorsum rough and warty, finger 2 length equal to or less than finger 4 length, finger 1 less finger 3 length, outer metatarsal tubercle absent, tibio tarsal tubercle absent, length of inner metatarsal tubercle more than three times the inner toe length and reduced webbing. We also provide 16S rRNA gene sequence for S. pashchima sp. nov. and show that it is genetically distinct from species of Sphaerotheca for which genetic data is available.

    Keywords: Amphibia, molecular phylogeny, taxonomy.

    Sphaerotheca pashchima sp. nov.
     Suggested common name: Western Burrowing Frog

    Holotype: BNHS 6000, male (41.0mm SUL), 05.vi.2016, India: Maharashtra: Saswad-Waghapur Road, Ambodi Village (18.3500N, 74.0410E, 747m), coll. S. Sulakhe et al.

    Diagnosis: Sphaerotheca pashchima sp. nov. differs from all other congeners based on the following combination of characters: interorbital width less than upper eyelid width; snout to nostril distance less than half of eye diameter; nostril nearer to snout than to eye; internarial distance greater than inter orbital distance; snout rounded; dorsum rough and warty; finger 2 length equal to or less than finger 4 length; finger 1 less finger 3 length; outer metatarsal tubercle absent; tibio tarsal tubercle absent; length of inner metatarsal tubercle more than three times the inner toe length; and webbing formula I1--2-II1-3-III2-3½IV3½-2+V.

    Etymology: Pashchim’ (Sanskrit), means ‘west’ and is used to signify the distribution of the species in western India. Name is noun in apposition.

    Habitat and ecology: S. pashchima is found widely distributed in western India. It inhabits variety of habitats from high to low rainfall areas. In high rainfall areas it is sympatric to S. dobsonii. It is also found in semi arid and arid parts of Deccan plateau. In semi arid and arid areas it breeds in temporary rain water pools immediately after the first flash rains. Adults gather in large numbers at potential breeding habitats. Tadpoles are bottom dwelling and frequently come to the surface of water for breathing. Juveniles are cannibalistic; a larger one devours the smaller one of its own species.

    Distribution: Western parts of peninsular India from the states Gujarat, Maharashtra and Karnataka (Image 3).

    DISCUSSION: 
    Dahanukar et al. (2017) provide a review of the species under the genus Sphaerotheca and identify three morphological groups for eight valid species in the genus. They also assign genetic barcode for S. breviceps, S. dobsonii and S. pluvialis so as to aid future studies in unambiguous identification of these three species. We describe S. pashchima sp. nov. from the S. breviceps group, which is morphologically distinct from all its congeners. We also provide genetic barcode as identity of the new species.
    It is essential to note that earlier reports of S. breviceps by Padhye & Ghate (2002), Padhye et al. (2002), Dharne et al. (2004), Dahanukar & Padhye (2005), and Padhye & Ghate (2012) should be attributed to S. pashchima sp. nov. based on current study.
    Dahanukar et al. (2017) mention that the sequence GU191122 for specimen identity as S. rolandae from Rajasthan is not of good quality and with several gaps; however, partial sequence comparison suggests that the species is misidentified and is likely to be S. pashchima sp. nov. indicating its presence in Rajastan.

    [Herpetology • 2017] Rediscovery and Range Extension of the Guinean Skink Trachylepis keroanensis (Chabanaud, 1921) (Squamata: Scincidae)

    Trachylepis keroanensis  (Chabanaud, 1921)


      Abstract

     We report the rediscovery of the skink Trachylepis keroanensis (Chabanaud, 1921) 90 years after its description. For the first time pictures of live specimens are shown and the known, now extended, distribution is presented. The clear morphological differences (body shape, colouration and most notably ratio tail length to body length) towards Trachylepis perrotetii (Duméril & Bibron, 1839), which justify the species status, are confirmed.

    [Ornithology • 2017] Amazona gomezgarzai • A New Parrot Taxon from the Yucatán Peninsula, Mexico — Its Position within Genus Amazona based on Morphology and Molecular Phylogeny

    Amazona gomezgarzai
     Silva​, Guzmán, Urantówka & Mackiewicz, 2017


    Abstract

    Parrots (Psittaciformes) are a diverse group of birds which need urgent protection. However, many taxa from this order have an unresolved status, which makes their conservation difficult. One species-rich parrot genus is Amazona, which is widely distributed in the New World. Here we describe a new Amazona form, which is endemic to the Yucatán Peninsula. This parrot is clearly separable from other Amazona species in eleven morphometric characters as well as call and behavior. The clear differences in these features imply that the parrot most likely represents a new species. In contrast to this, the phylogenetic tree based on mitochondrial markers shows that this parrot groups with strong support within A. albifrons from Central America, which would suggest that it is a subspecies of A. albifrons. However, taken together tree topology tests and morphometric analyses, we can conclude that the new parrot represents a recently evolving species, whose taxonomic status should be further confirmed. This lineage diverged from its closest relative about 120,000 years ago and was subjected to accelerated morphological and behavioral changes like some other representatives of the genus Amazona. Our phylogenies, which are so far the most comprehensive for Amazona taxa enabled us to consider the most feasible scenarios about parrot colonization of the Greater and Lesser Antilles and Central America from South America mainland. The molecular dating of these migrations and diversification rate were correlated with climatic and geological events in the last five million years, giving an interesting insight into Amazon parrot phylogeography and their evolution in general.

    Amazona gomezgarzai, sp. nov. (Figs. 2–7)

    Holotype. Adult male, MEXICO, the Yucatán Peninsula, south of Becanchén in Tekax Municipality. The holotype is represented by the feathers of the male, which were deposited in the collection of the Laboratorio de Ornitología, Facultad de Ciencias Biologícas, Universidad Autonóma de Nuevo León, Mexico and were assigned catalog number: MGG01-Amazona gomezgarzai-holotipo. Article 72.5.1 of the Code of Zoological Nomenclature (henceforth CODE) permits the use of animal parts in the designation of a type specimen. Upon death of the living bird, its preserved body will be paired to the feathers for a complete body. This complies with Article 16.4.2 of the CODE, which states that where the holotype is an extant individual, a statement of the intent to deposit the individual in a collection upon its death accompanied by a statement indicating the name and location of that collection is sufficient.

    Paratype. Adult female collected in the same locality as the holotype. Like the holotype, feathers from this specimen have been deposited in the collection and have assigned catalog number: MGG02-Amazona gomezgarzai-alotipo. Upon its death, it will be added to the collection in Laboratorio de Ornitología, Facultad de Ciencias Biologícas, Universidad Autonóma de Nuevo León, Mexico.

    Etymology. We take extreme pride in naming this parrot after Miguel Angel Gómez Garza, a Mexican veterinarian born in Monterrey (Nuevo León, Mexico) in 1960. Gómez Garza’s interest in the ecology of the parrots of Mexico spans decades and culminated in the publication of a work specifically dealing with the psittacines of that country (Gómez Garza, 2014). During his professional lifetime, Gómez Garza has been deeply involved in rehabilitating confiscated wildlife. For the last thirty years, in his private veterinary clinic (Veterinaria del Valle) in Monterrey, he has honorably supported the wildlife protection agency of the Republic of Mexico, Procuraduría Federal de Protección al Ambiente (PROFEPA), providing medical attention to confiscated wildlife suitable for being returned to their natural habitat. As a researcher in the Facultad de Medicina Veterinaria y Zootecnia of the Universidad Autonóma de Nuevo León, he is presently working on a veterinary protocol for confiscated psittacines intended for reintroduction to the wild. He brought the existence of this unique member of the genus Amazona to our attention and to him science and we owe a debt of gratitude. We suggest the common name in English: blue-winged Amazon and in Spanish: Loro de alas azules.

    Distribution. The new Amazona is endemic to the Yucatán Peninsula in southern Mexico. To date, its presence is confined to an area roughly 100 km2 that is centered south of Becanchén in Tekax Municipality, Yucatán. No part of the range is presently protected in any form.

    Habitat. The new Amazona is found in tropical caducifolius and subcaducifolius forest. It is also found in disturbed patches of native vegetation and in small, cultivated fields with scattered trees. It is found below 300 m above sea level.

    Natural history. Miguel A. Gómez Garza first sighted this parrot in the field in trees of the Leucaena genus at heights of approximately 6 m in the beginning of 2014 during a visit to the south of Becanchén, in the municipality of Tekax. The parrots occurred in small flocks of three to five individuals and fed on the tender pods produced by this tree. During a follow up visit in August 2014, Gómez Garza also sighted pairs with their fledged young. This field work confirmed the rarity of the species and that it was far less common than the other two species found in the same area, Amazona albifrons nana and Amazona xantholora.

    In normal parrot fashion, the new Amazona is diurnal, beginning the day at sunrise. It is generally secretive when resting, using its plumage as camouflage. In contrast, it is vocal and noisy in flight. The flight is moderately fast with the mechanism that is typical of the genus Amazona with wing-beats never exceeding the horizontal axis.

    The new Amazona is found in small flocks of less than 12 individuals, which were studied in the field. Pairs and their progeny have a tendency to remain together and are discernible in groups. Like all members of the genus Amazona, this parrot is herbivore. Its diet consists of seeds, fruits, flowers and leaves obtained in the tree canopy. It also consumes tender shoots of native trees and the pods of leguminous trees including uaxim (Leucaena glauca), bukut (Cassia grandis) and katsín (Acasia gaumeri).

    Very little is known about this parrot’s biology. There is no conservation program currently in effect to preserve this parrot but its long-term existence impinges on the local communities and making them aware of this parrot’s value as a result of its uniqueness, its potential as a bird watching attraction and the fact that it is present only locally. Its small range and rarity should make its conservation a priority.
