The paper describes two new species of feather mites collected from the blue-throated blue flycatcher Cyornis rubeculoides (Vigors) (Passeriformes: Muscicapidae) in India (Meghalaya): Trouessartia kharkhanensis Constantinescu et al. sp. nov. (Trouessartiidae) and Proterothrix cyornissimilis Constantinescu et al. sp. nov. (Proctophyllodidae: Pterodectinae). Both sexes of T. kharkhanensis differ from the closest species, T. rubecula Jablonska, 1968 by having setae si and c2 lanceolate and setae c3 and sRIII with acute apex. In males of the new species, the adanal apodemes have a hook-like retroverse apophysis and the internal margins of terminal lamellae have a shallow invagination at the level of setae h3. Both sexes of P. cyornissimilis differ from the closest species, P. cyornis Mironov and Tolstenkov, 2013, mainly by the ornamentation of the dorsal shields: it is absent on the prodorsal shield and poorly expressed on the hysteronothal shield. In males of the new species, the supranal concavity is triangular and the genital arch has a pair of small ovoid sclerites at its tips. http:/zoobank.org/urn:lsid:zoobank.org:pub:1671D6D4-8895-467B-A124-05EDBB0DF406 © 2017 Informa UK Limited, trading as Taylor & Francis Group

Two new species of the feather mite family Pteronyssidae (Acariformes: Analgoidea) from passerines of the families Leio-thrichidae and Pycnonotidae in India (Meghalaya, East Jaintia Hills District) are described: Timalinyssus actinodurae Constantinescu sp. nov. from Actinodura cyanouroptera (Hodgson) (Leiothrichidae) and Pteroherpus meghalayensis Constantinescu sp. nov. from Hemixos flavala Blyth (Pycnonotidae). Timalinyssus actinodurae differs from all of the oth-er species of the genus due to a particular shape of the opisthosomal lobes in both sexes and having a strong sclerotised band in postero-median area of the hysteronotal shield in male. The male of Pteroherpus meghalayensis differs due to a very long genital apparatus and unusual length of the tips of epiandrum that extend the level of the genital apparatus.

The article describes a new species of the feather mite subfamily Pterodectinae from the Little Spider-hunter Arachnothera longirostra Temminck, 1826 (Passeriformes, Nectariniidae) in India. Pedanodectes angustilobus sp. n. differs from all known Pedanodectes species by having opisthosomal lobes short, at base wider than long, roughly rounded apically in males, and strongly elongated and narrowed lobar region with wide terminal appendages in females. A key to species of the genus Pedanodectes is presented. © Ioana Cristina Constantinescu et al.

The article describes a new species of the feather mite family Pteronyssidae (Acarina: Psoroptidia) from the Gray Sibia Heterophasia gracilis (McClelland) (Passeriformes, Leiothrichidae) in India (Meghalaya, Jaintia Hills, Shnongrim village). Males of Timalinyssus wahlangi sp. n. differ from those of all Timalinyssus species by having the horseshoe-shaped epiandrum with a short anterior extension. Females of the new species differ from those of all previously known species of the genus in having the hysteronotal shield with deep lateral incisions between e2 and f2 setae. A key to all species of the genus Timalinyssus is presented. Copyright Ioana C. Constantinescu et al.

Two new feather mite species of the genus Trouessartia Canestrini are described from laughingthrushes (Passeriformes: Leiothrichidae) captured in Meghalaya (India): Trouessartia cyanouropterae sp. n. from Actinodura cyanouroptera (Hodgson) and Trouessartia alcippeae sp. n. from Alcippe nipalensis (Hodgson). It is the first time when species of the genus Trouessartia are described from leiothrichids. © Ioana C. Constantinescu et al.

Two new feather mite species of the genus Trouessartia Canestrini are described from birds captured in Meghalaya (India): Trouessartia longidenticulata Constantinescu sp. n. from Pycnonotus cafer (Linnaeus) (Passeriformes, Pycnonotidae) and Trouessartia dicruri Constantinescu sp. n. from Dicrurus aeneus (Vieillot) (Passeriformes, Dicruridae). In the genus Trouessartia, males of T. longidenticulata show a unique character state in having the lamellae of the opisthosomal lobes with long and sharp denticles. Both sexes of T. dicruri differ from closely related T. delicatula Gaud, 1952 by smaller body size (T. dicruri males are 420-452 long, females 500-532 long, vs. c. 575 and 595, respectively in T. delicatula); males have the adanal apodemes without apophyses and the terminal lamellae in a shape of a parallelogram (vs. the adanal apodemes have a pair of apophyses and the terminal lamellae are semi-ovate); the opisthosomal lobes do not touch each other at the inner margins (vs. the opisthosomal lobes touch each other at the inner margins, at the level of setae h3); in females, setae h1 are lanceolate (vs. spiculiform).

Objectives: To evaluate the toxicity levels of the aqueous extract of Allium sativum on Cyprinus carpio. Methods: Fresh garlic (A. sativum) was procured from a local market in Shillong, Meghalaya, India; and the crude aqueous extract of which was used in the acute toxicity tests to determine the 96 hrs median lethal concentration 50% (96 hrs LC50) on juvenile common carp (C. carpio) via bath immersion treatment. Results: The 96 hrs LC50 of the aqueous garlic extract for juveniles of C. carpio was estimated to be 253.19 mg/L. Furthermore, fish exposed to the different concentrations of the aqueous garlic extract exhibited abnormal behavior. The susceptibility of C. carpio to the lethal effects of the aqueous garlic extract was duration and concentration-dependent. Fish mortality was found to be associated with the decrease in pH values. Conclusion: The current study indicates that the aqueous garlic extract has a low toxicity on C. carpio and therefore can be safely used in this species for any experimental purpose. Besides this, it also provides baseline information on the dosage for the aqueous garlic extract to be used as a potential management tool in aquaculture. © 2016, Innovare Academics Sciences Pvt.

Probiotics are live microbes which when administered in adequate amounts as functional food ingredients confer a health benefit on the host. Their versatility is in terms of their usage which ranges from the humans to the ruminants, pigs and poultry, and also in aquaculture practices. In this review, the microorganisms frequently used as probiotics in human and animal welfare has been described, and also highlighted are the necessary criteria required to be fulfilled for their use in humans on the one hand and on the other as microbial feed additives in animal husbandry. Further elaborated in this article are the sources from where probiotics can be derived, the possible mechanisms by which they act, and their future potential role as antioxidants is also discussed.
