A new species of potamid crab of the genus Badistemon Yeo & Ng, 2007, is described from Kamjong district of Manipur, India. Badistemon fulvum n. sp., can be distinguished from congeners by a distinct combination of carapace and gonopod characters: carapace subquadrate, convex, dorsal surface glabrous, cervical groove superficial, anterolateral margin longer than posterolateral margin; cornea relatively large; sixth male pleonal somite trapezoidal in shape, male telson broader than long; terminal segment of male first gonopod relatively long, outwardly bent, sub cylindrical with low and short dorsal flap, tip pointed, groove for male second gonopod terminal. Holotype and paratypes of Potamiscus pealianus (Wood-mason, 1871) are re-examined, and the species is here referred to Badistemon as carapace morphology and male gonopods characters are found congeneric with the genus. A key for all the three species of Badistemon are provided.

Osborne-Cotterill lesion is an osteochondral fracture located in the posterolateral margin of the humeral capitellum, which may be associated with a defect of the radial head after an elbow dislocation. This lesion causes instability by affecting the lateral ulnar collateral ligament over its capitellar insertion, which is associated with a residual capsular laxity, thereby leading to poor coverage of the radial head, and hence resulting in frequent dislocations. We present a 54-year-old patient, a physician who underwent trauma of the left elbow after falling from a bike and suffered a posterior dislocation fracture of the elbow. The patient subsequently presented episodes of instability, and additional work-up studies diagnosed the occurrence of Osborne-Cotterill lesion. An open reduction and internal fixation of the bony lesion was performed, with reinsertion of the lateral ligamentous complex. Three months after surgery, the patient was asymptomatic, having a flexion of 130º and extension of 0º, and resumed his daily activities without any limitation. Currently, the patient remains asymptomatic 2 years after the procedure. Elbow instability includes a large spectrum of pathological conditions that affect the biomechanics of the joint. The Osborne-Cotterill lesion is one among these conditions. It is a pathology that is often forgotten and easily overlooked. Undoubtedly, this lesion requires surgical intervention.

Ryukyua circularis (Pillai, 1954) is recorded here for the first time on the host Amblygaster clupeoides Bleeker, 1849 from Indian waters. The species is redescribed with illustrations of the gravid female, adult male and manca from its type locality, and the known hosts and geographical records of the species are reviewed. Ryukyua circularis is readily identified from the oval to rounded body shape, widest at pereonite 3–5; cephalon deeply immersed in pereonite 1; mandible palp with the spiny surface, article 3 with a long terminal setae; pleonite 1–3 partially overlapped by a posterolateral margin of pereonite 7; pleotelson anterior lateral margins weakly convex, posterior margin evenly rounded, without median point.

Two new Brazilian Protoneurinae damselflies,Forcepsioneurareguasp. nov. (holotype male deposited in DZRJ: Brazil, Rio de Janeiro State, Cachoeiras de Macacu municipality, RPPN Reserva Ecológica de Guapiaçu) andForcepsioneuraserrabonitasp. nov. (holotype male deposited in DZRJ: Brazil, Bahia State, Camacan municipality, RPPNs Serra Bonita) , are described, illustrated and diagnosed based on males and females. The bluish and smallerF.reguasp. nov. has been confused with at least three previously described species, being very similar to the type species ofForcepsioneura,F.garrisoniLencioni, 1999, but lacking a defined tubercle-like process on the posterolateral margin of the median lobe of the prothorax in both sexes, which allows it to be distinguished from all other known species. The shape of the cercus of the male ofF.serrabonitasp. nov. is similar to that ofF.grossiorumMachado, 2001 andF.luciaMachado, 2000, two species with very short ventrobasal process. However, it differs from them mainly by the mediobasal process of the cercus, which is rounded in dorsal view and almost not visible in lateral view. The taxonomic status ofForcepsioneurais discussed and a comparison with the other species of the genus is provided. Based on size, habitat and coloration,Forcepsioneuracan be informally divided into two groups: (1) large, orange-black and montane species, includingF.grossiorum,F.itatiaiae(Santos, 1970),F.luciaandF.serrabonitasp. nov.; (2) small, bluish and lowland species, includingF.garrisoni,F.haerteliMachado, 2001,F.reguasp. nov. andF.sancta(HageninSelys, 1860). Our findings highlight the urgency in directing collecting efforts to unexplored areas, as well as the importance of private preserves that harbor the type localities as guardians of the threatened and diverse Atlantic Forest diversity. Together these two localities surveyed account for more than 210 species of odonates, representing almost 24% of the number of Brazilian species. Brazil has the greatest number of known species of odonates in the world. This study shows that further research is required in order to fully understand the diversity ofForcepsioneura.

A new species of rhizopine crab of the genus Typhlocarcinus Stimpson, 1858 (family Pilumnidae), is described from southwestern India. Typhlocarcinus kerala sp. nov. is characterised by its granular carapace with the dorsal regions well demarcated and the gastro-cardiac grooves deep, the anterolateral margin entire and prominently granulated, the posterolateral margin lacks a low granulated lobe, proportions of the ambulatory legs and shape of the female telson.

We review the endemic Australian bee fly genusEusurbusRoberts (Bombyliidae, Bombyliinae) and recognize two described species and three new species. The monotypic genusBromoglycisHull is identified as a new junior synonym ofEusurbus. Another species,E. nigracinctusRoberts, is designated as the type species of a new genusZentamyiagen. nov. This new genus is similar toEusurbusbased on several combined external characters including two-segmented palp, one-segmented flagellomere, open anal cell and cellr5, and the cellbrmuch longer than cellbm. However,Zentamyiagen. nov. has a more flattened scutum, and the apex of the flagellum is tapered. Moreover, the male genitalia are very different fromEusurbus, the male epandrium is narrow and long, and its posterolateral margin has a cluster of dense hairs; the female lacks a sand chamber, and the sperm pump is long and strong. A morphological phylogeny toEusurbusspecies is provided.

A new species of the temnospondyl tetrapod, Sclerocephalus stambergi n. sp., is described from the early Permian deposits of the Boskovice Basin in Moravia (Czech Republic). The length of the skull of the only known specimen is about 50 mm. Characters including the well-ossified quadrate, septomaxilla and scapulocoracoid, presence of the maxilla-nasal suture and a free posterolateral margin of the supratemporal suggest an early adult age. This new species of Sclerocephalus is distinguished from the others on the basis of the following characters: nasal and maxillary processes of the premaxilla of equal width; absence of the alary process of the premaxilla; distinct pointed process on the lacrimal between the maxilla and jugal; narrow interclavicle; and very peculiar tabular presenting a quadrangular, plate-like process extending from its posterolateral portion, an almost right angle between its lateral and posterior margins, and a long posteromedial process. The new species represents the smallest and possibly the most basal Sclerocephalus species. The specimen described here sheds new light on the anatomy and taxonomy of Sclerocephalus. It completes the biodiversity of the tetrapod fauna from the Boskovice Basin, and our knowledge on the evolution of the European Paleozoic temnospondyls.

<em>Kemkemia auditorei</em> Cau &amp; Maganuco, 2009 was recently described as a new genus and species of theropod dinosaur on the basis on an isolated distal caudal vertebra. The holotype and only known specimen comes from Kem Kem beds (Upper Cretaceous) of Morocco. In the present paper we review the phylogenetic position of <em>Kemkemia</em> and we conclude that this taxon belongs to Crocodyliformes. It shares with crocodyliforms the presence of a concavity at the posterolateral margin of neural spines, an inflated neural canal, and reduced prezygapophyses, among other traits. This combination of characters clearly distinguishes <em>Kemkemia</em> from theropod dinosaurs. In this way, <em>Kemkemia</em> is here considered as a Crocodyliformes <em>incertae sedis</em>, and based on the absence of unique characters, the genus and species <em>Kemkemia</em> auditorei is proposed as a nomen <em>dubium</em>.
