Black mildews belong to a wide range of leaf inhabiting fungal genera, which causes severe damage to the living leaves, affect photosynthetic efficiency, cause physiological imbalances, and reduces the plants’ aesthetic value. During a survey of foliicolous fungi in Vagamon hills of Kerala state’s Western Ghats region, an endemic medicinal plant Xanthophyllum arnottianum was found infected with an undescribed species of black mildew causing fungal genus Echidnodella.  Their mycelia are non-appressoriate and devoid of hypostroma. Thyriothecia are oval, ellipsoidal, X or Y shaped, elongated producing eight uniseptate brown coloured ascospores in each bitunicate asci. Echidnodella was distinguished from the allied genus Echidnodes in the absence of paraphyses and from the genera Lembosia and Morenoella in the lack of appressoria (haustoria). This new species, Echidnodella vagamonensis is described and illustrated in detail to provide the consolidated account of the species known on this host genus.

A new species of the oriental shrub frog genus Philautus is described from Kakkayam Reserve Forest of Calicut district, Kerala state, in the southern Western Ghats. This species is distinguished from congeners by the combination of characters such as body small, elongate, squat and flat; head arched, wider than long; snout short rounded, equal or sub equal to diameter of eye; canthus rostralis rounded; tympanum indistinct but visible; eyes protruding, pupil with striking golden yellow dentition like marks; belly granular; vocal sac unpigmented; fleshy brown to cream yellow dorsum with two distinct golden yellow lateral bands bordered by dark brown from upper eyelid to the posterior part of flanks. A description of the advertisement calls and ecology and natural history notes are also provided for the new species which so far is only known from the type locality.

A new species of Tyrannomyrmex (Hymenoptera, Formicidae), T. alii sp. nov., is described from the Western Ghats of Kerala State in southern India. This new species can be distinguished from other Tyrannomyrmex species using morphological characters, from T.dux by the petiolar shape, and from T. legatus and T.rex by surface sculpture and pilosity. The gyne of the genus is described for the first time. We provide detailed morphological descriptions of the gyne and worker castes, images from scanning electron microscopy, a key to all four known species of Tyrannomyrmex, and a note on the ecology of this rare genus.

Utricularia sunilii, a new species of Utricularia Sect. Oligocista from Kerala state of Western Ghats is described here. The new species shows similarities with U. graminifolia in having 3-nerved foliar organs and thickened capsule wall along the margin of dehiscence but differs by deeply 3-lobed lower lip of corolla.

Abstract The late Paleozoic temnospondyl Sclerocephalus formed an aquatic top predator in various central European lakes of the late Carboniferous and early Permian. Despite hundreds of specimens spanning a wide range of sizes, knowledge of the endocranium (braincase and palatoquadrate) remained very insufficient in Sclerocephalus and other stereospondylomorphs because even large skulls had unossified endocrania. A new specimen from a stratigraphically ancient deposit at St. Wendel in southwestern Germany is recognized as representing a new taxon, S. concordiae new species, and reveals a completely ossified endocranium. The sphenethmoid was completely ossified from the basisphenoid to the anterior ethmoid region, co-ossified with the parasphenoid, and the basipterygoid joint was fully established. The pterygoid bears a slender, S-shaped epipterygoid, which formed a robust pillar lateral to the braincase. The massive stapes was firmly sutured to the parasphenoid. In the temnospondyl endocranium, character evolution involved various changes in the epipterygoid region, which evolved distinct morphologies in each of the major clades.
