The genus Paratymolus Miers, 1879, currently contains nine described species. Paratymolus apelin.sp. is described herein, based upon a male from the Persian Gulf. The new species is close to Paratymolushastatus Alcock, 1895, but can be distinguished from the all congeners by carapace characters and particularly by the unique morphology of the male first gonopod. http://zoobank.org/urn:lsid:zoobank.org:pub:81E29FA2-2AA7-40DA-B7D1-E80D231A997B

The purpose of this study is to provide information on the leech fauna of North Africa. This overview is based primarily on collected material, data from the literature and material in museum collections. A total of 37 species belonging to 6 families and 19 genera are presently known. Among these species, eight represent new records for North African countries. This report includes the first records for Tunisia of one freshwater leech, Helobdella stagnalis (Linneaus, 1758), and one marine leech, Trachelobdella lubrica (Grube, 1840). Four taxa are reported as new for Algeria: two marine species (Pontobdella muricata Linnaeus, 1758 and Branchellion torpedinis Savigny, 1822) and two freshwater subspecies (Dina punctata punctata Johansson, 1927 and Dina punctata maroccana Nesemann & Neubert, 1994). Pontobdella muricata is reported for the first time from Morocco and Alboglossiphonia iberica Jueg, 2008, previously known only from the Iberian Peninsula, is now reported from Morocco.

The nest of Minixi suffusum offers a rare form of mimicry: bird dropping masquerading of the nest by the potter wasp was recorded in mid-western Brazil, in the municipality of Dourados MS. Nesting biology of M. suffusum and the material involved in the action of the camouflage were observed. Eleven nests were sampled, with a total of 38 cells. Use of uric acid for staining the cell was evident in all nests. The way that the wasp stains the cells was observed. Substrate nest site, seasonality, larvae biology, sex ratio, prey and parasitoids of M. suffusum were reported. Nest camouflage may be related to defense against natural enemies.

The genus Hieroglyphus Krauss, 1877 is reviewed and a key to all the species is given. Diagnoses of all the previously known species from India are given. Four species are redescribed and illustrated along with description and illustration of one new species (H. acuticercus) from western Uttar Pradesh. The characteristic feature of the new species is the presence of acute male cercus which makes it different from the other species. The finding of this study will be useful in making predictions about the relationships of this group and for accurate identifications of the species in the future.http://zoobank.org/urn:lsid:zoobank.org:pub:986059C4-CB77-F27-A937-DB6F51AC7DAC

In this study, the sex ratio, habitat use, and diet of free-ranging Kinixys nogueyi are examined. Sex ratio and habitat use were examined in Togo and Nigeria (West Africa), and food habits only in Nigeria. Sex ratios were equal in both populations. Tortoises had clear habitat preferences in both countries, and the Nigerian population exhibited seasonal but not inter-sexual differences in habitat selection. The present study demonstrated that this species inhabits not only Guinea savannahs and relatively wet savannahs, as already reported in the literature, but also rainforest patches and hilly forests, especially in Togo. Food remains in the feces of Nigerian specimens belonged to plants and fungi as well as to animals, with inter-seasonal but not inter-sexual differences in dietary composition. In particular, there was a significant shift from a diet based mostly on animal food in the dry season towards a mainly vegetarian diet in the wet season.

This study was conducted to determine the population dynamics of Penaeus merguiensis stock in the coastal waters of the Persian Gulf. A total of 4994 male and 5264 female prawns were collected monthly by a bottom-trawl net, from July 2010 to September 2012. The carapace length and weight relationship demonstrated that growth in both sexes was allometric. The asymptotic carapace length (CL∞) was estimated at 48 mm for males and 54 mm for females. The growth parameter K was calculated as 1.6 Yr− 1 for males and 1.8 Yr− 1 for females. The total mortality rate for males was more than that for females. And the exploitation rates were 0.75 for males and 0.69 for females. The sex ratio identified that it was not a constant 1:1 throughout the year, with 51.3% females. Banana prawns can spawn all year round and have a spawning peak from February to May. The Lm50% was estimated at a carapace length of 33.64 mm. The exploitation of P. merguiensis in the area is intended to protect spawners and juvenile stock for renewal. Also, the results showed that long-term monitoring is still required to better understand P. merguiensis population dynamics.
本研究旨在确定波斯湾沿岸水域merguiensis种群的种群动态。2010年7月至2012年9月，每月采用底拖网法捕获雄对虾4994尾，雌对虾5264尾。甲壳长度与体重的关系表明两性的生长都是异速生长。雄性的渐近甲壳长度(CL∞)为48 mm，雌性为54 mm。计算的生长参数K为男性1.6 Yr - 1，女性1.8 Yr - 1。男性的总死亡率高于女性。雄虫的剥削率为0.75，雌虫的剥削率为0.69。性别比确定它不是全年不变的1:1，有51.3%的女性。香蕉对虾全年可产卵，2月至5月为产卵高峰。据估计，l50%的甲壳长度为33.64 mm。在该地区开发麦桂鱼是为了保护产卵和幼鱼种群的更新。同时，还需要进行长期的监测，以更好地了解麦桂水杨的种群动态。

Knowledge about habitat requirements of wildlife is a basic need for conservation. We characterized the roost sites of the spotted owlets Athene brama evaluating 134 open limb and 95 cavity roost trees during 2007–2009 from Madurai district, southern India. Roosts occurred most often in banyan trees Ficus benghalensis (47.0% of open limb and 36.8% of cavity roosts). Number of cavity openings and height of lowest limb differed significantly between open limb and cavity roosts (Mann–Whitney U test, P < 0.05). The spotted owlets used larger trees with a wider basal circumference and canopy volume for open limbs, while roost height, diameter at breast height, total limbs, number cavity openings, and height of lowest limb were larger in cavity roosts. The roost trees were closer to human settlements than other habitat types. Based on our results, we concluded that the spotted owlets preferred roost trees closer to foraging areas and large tree with dense canopy because the roosts located in larger trees are protected from sunlight exposure and provide cover from predators.

First and foremost, forensic entomology requires the correct identification of the specimens found on a corpse. Among the fly families of greatest forensic importance, the Sarcophagidae (flesh flies) has fewer published keys for the identification of species. Also, identification of flesh flies is not a trivial task due to the complexity of the diagnostic characters found in the male genitalia. To fill this lacuna, here we provide a pictorial key to the species of Sarcophagidae of potential forensic importance found in the central Amazon region of Brazil. This key includes pictures of the main diagnostic characters for 23 species in four genera of Sarcophaginae. As a consequence of preparing this key, we discovered and present new species records for central Amazon.

One new genus (Quatuordillo) and two new species (Quatuordillo caecus and Buddelundia eberhardi) are described from subterranean habitats in Western Australia. Both species show troglomorphic traits, such as body depigmentation, reduction or absence of eyes, and elongation of appendages. Buddelundia eberhardi is the only troglobiont in the genus, which up to date includes 26 species from Australia. Armadillo brevicauda Dollfus, 1898 from Flores Island, Indonesia, is transferred to Buddelundia. http://zoobank.org/urn:lsid:zoobank.org:pub:35F61AC8-F76D-49E8-A8D8-278B58C2FE31

This study focuses on evaluating the pattern of shell utilization by the hermit crab Clibanarius zebra collected from the intertidal zone of four different sites along the Saurashtra coast, Gujarat, India. Specimens were collected monthly from March 2012 to August 2013 during low tide; hermit crab weight (HW) and their shield length (SL) were measured. Gastropod shells were identified and different morphological variables were recorded [dry weight (DW), shell length (SHL), shell aperture length, and shell aperture width]. A total of 804 hermit crabs occupying 23 gastropod species were collected. Cerithium scabridum (41.8%) was the shell most occupied by the crabs followed by Turbo intercostalis (10.6%), Astrea stellata (7.8%), Lunella coronata (6.6%), and Chicoreus brunneus (5.6%). Significant difference was obtained in the percentage of shell occupation between sexes. Regression analysis showed a high correlation between the different morphological variables of hermit crabs and gastropod shells; the highest values of correlation were obtained between HW and DW. The high values of correlation coefficient and regression models between the different morphological variables of hermit crabs and gastropod shells suggest that shell architecture has a huge impact on shell utilization pattern of C. zebra.

Specimens were collected monthly from March 2012 to August 2013 during low tide; hermit crab weight (HW) and their shield length (SL) were measured. Gastropod shells were identified and different morphological variables were recorded [dry weight (DW), shell length (SHL), shell aperture length, and shell aperture width]. A total of 804 hermit crabs occupying 23 gastropod species were collected. Cerithium scabridum (41.8%) was the shell most occupied by the crabs followed by Turbo intercostalis (10.6%), Astrea stellata (7.8%), Lunella coronata (6.6%), and Chicoreus brunneus (5.6%). Significant difference was obtained in the percentage of shell occupation between sexes. Regression analysis showed a high correlation between the different morphological variables of hermit crabs and gastropod shells; the highest values of correlation were obtained between HW and DW. The high values of correlation coefficient and regression models between the different morphological variables of hermit crabs and gastropod shells suggest that shell architecture has a huge impact on shell utilization pattern of C. zebra.","PeriodicalId":54409,"journal":{"name":"Tropical Zoology","volume":"27 1","pages":"129 - 139"},"PeriodicalIF":0.9,"publicationDate":"2014-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03946975.2014.964923","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59381924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
