A new genus of archidermapteran earwigs is described for Brevicula teres Tihelka (Dermapteridae) from Sinemurian deposits of the Black Ven Mudstone Member, Charmouth Mudstone Formation, Dorset, United Kingdom. Dacryoderma Engel, new genus, is distinct from Brevicula Whalley in the broadly rounded anterior tegminal border lacking a submedial hump and overall teardrop shape, with the anterior margin tapering gradually in a comparatively straight line to the more acutely rounded apex. The following new combination is established: Dacryoderma teres (Tihelka).

Based on the morphology of workers, gynes and males, we revise the taxonomy of nominal taxa traditionally included by authors in the fungus-growing ant genus Mycetophylax. Our results indicate that Mycetophylax Emery (Myrmicocrypta brittoni Wheeler, 1907, type species, by designation of Emery, 1913; junior synonym of Cyphomyrmex conformis Mayr, 1884 by Kempf, 1962) includes M. conformis, M. simplex (Emery, 1888), and M. morschi (Emery, 1888) new combination (formerly in Cyphomyrmex), with several synonymies. Mycetophylax bruchi (Santschi, 1916) does not belong to the same genus and is diagnosed, in addition to other characters, by a psammophore arising at the anterior margin of the clypeus. For this species we are resurrecting from synonymy Paramycetophylax Kusnezov, 1956 (Mycetophylax bruchi as type species, by original designation, with M. cristulatus as its new synonym). Myrmicocrypta emeryi Forel, 1907 is the only attine in which females lack the median clypeal seta and have the antennal insertion areas very much enlarged and anteriorly produced, with the psammophore setae arising from the middle of the clypeus and not at its anterior margin as in Paramycetophylax. Notwithstanding its inclusion in Mycetophylax by recent authors, it is here recognized as belonging to a hitherto undescribed, thus far monotypic genus, Kalathomyrmex new genus (Myrmicocrypta emeryi as its type species, here designated). We redescribe workers, gynes and males of all species in the

‘Megalosaurus’ hesperis from the Inferior Oolite (Bajocian, Middle Jurassic) of Dorset, UK is redescribed. Several features of ‘M.’ hesperis demonstrate that it is distinct from the lectotype dentary of Megalosaurus: an enlarged, subcircular third alveolus and subcylindrical, anteriorly inclined anterior dentary teeth; an anterior Meckelian foramen located almost directly anterior to the posterior Meckelian foramen; low interdental plates; and a prominent lip bounding the Meckelian groove ventrally, anterior to the Meckelian fossa. Therefore a new genus, Duriavenator, is erected to form the new combination D. hesperis. D. hesperis possesses two autapomorphies of the maxilla: a deep groove on dorsal surface of the jugal process containing numerous pneumatic foramina; and an array of small foramina in the ventral part of the articular surface for the premaxilla. Several features confirm the tetanuran affinities of D. hesperis: a prominent anterior process of the maxilla; the presence of band-like dental enamel wrinkles; the maxillary 'fenestra' is present but takes the form of an imperforate fossa (a spinosauroid synapomorphy); and the paradental groove is wide anteriorly, defining a distinct gap between the interdental plates and the medial wall of the dentary (a synapomorphy of Spinosauridae + Megalosauridae). Older records of tetanurans have been proposed, but most of these have been refuted and detailed re-examination of other early reports is warranted to establish the date of origin of this clade. An early Middle Jurassic origin of tetanurans is preferred.

A new genus, Dozierana gen. nov., is erected for Thionia gibbicollis Dozier, 1931 which is transferred from the family Issidae Spinola, 1839 to the family Nogodinidae Melichar 1898, subfamily Colpopterinae Gnezdilov, 2003. This new combination increases the fauna of Colpopterinae of Haiti Island up to 3 genera with 5 species. Accordingly, the family Issidae is no longer formally known from the island. Dozierana gen. nov. is characterized by wide metope, with distinct median carina and very weak sublateral carinae, upper margin of metope concave; coryphe 3 times as wide as long medially; large ocelli present; pronotum short, with 4 lateral carinae, its anterior margin strongly convex and posterior margin strongly concave; mesonotum 7 times as long as pronotum along midline, greatly elevated along median carina, with two lateral carinae joined with median one in shape of inverted “V”; fore wings wide, with wide hypocostal plate and rich cross-venation through whole wing, except subcostal area; basal cell large oblong-oval; costal vein with distinct upper keel appearing as a separate vein; clavus as long as whole wing, open; hind tibiae with single lateral spine subapically.

The small lacewing genus Apertochrysa comprises species from Africa, Asia and Australia. All lack a tignum, but otherwise resemble distantly related genera. We show that Apertochrysa does not form a monophyletic clade, based on analyses of molecular sequence data and morphological traits such as the presence and shape of the male gonapsis, wing venation, and larval setae. Apertochrysa kichijoi forms a clade with Eremochrysa, Suarius and Chrysemosa, whereas A. albolineatoides belongs to a clade that includes Cunctochrysa. Apertochrysa albolineatoides should become a new combination as Cunctochrysa albolineatoides, while A. kichijoi will have to be transferred to a new genus. The Australian A. edwardsi, the African A. eurydera and the type species of the genus Apertochrysa, A. umbrosa, join the large Pseudomallada group. Relationships of A. umbrosa are less certain, because for it we could amplify only one of the three nuclear genes used in the overall analysis. However, in all morphological traits tested, that species strongly resembles A. edwardsi and A. eurydera and thus is very likely just another exceptional Pseudomallada lacking a tignum. The fate of the genus name Apertochrysa depends on additional molecular and morphological analyses of A. umbrosa.

A new genus and species of the cockroach family Caloblattinidae, Dazhublattella lini gen. et sp.n., is described from the Upper Triassic Xujiahe Formation of Sichuan Province, in southwestern China. The new taxon is similar to the Triassic Caloblattina mathildae (Geinitz, 1883) (Vršanský & Ansorge 2007) in the venation and pattern, but differs in the less elongated forewing with arched anterior margin. An elemental analysis of the wing is undertaken using Energy Dispersive X-ray analysis.

AbstractThe crustose lichen genus Mycoblastus in the Northern Hemisphere includes eight recognized species sharing large, simple ascospores produced 1–2 per ascus in strongly pigmented biatorine apothecia. The monophyly of Mycoblastus and the relationship of its various species to Tephromelataceae have never been studied in detail. Data from ITS rDNA and the genes coding for translation elongation factor 1-α and DNA replication licensing factor mini-chromosome maintenance complex 7 support the distinctness of Mycoblastus s. str. from the core of the Tephromelataceae, but recover M. fucatus and an undescribed Asian species as strongly supported within the latter group. We propose accommodating these two species in a new genus, Violella, which is characterized by its brownish inner ascospore walls, Fucatus-violet hymenial pigment granules and secondary chemistry, and discuss the position of Violella relative to Calvitimela and Tephromela. We describe the new species Violella wangii T. Sprib. & Goffinet to accommodate a new species with roccellic acid from Bhutan, China, India and the Russian Far East. We also exclude Mycoblastus indicus Awasthi & Agarwal from the genus Mycoblastus and propose for it the new combination Malmidea indica (Awasthi & Agarwal) Hafellner & T. Sprib.

AbstractNeotherevella n.gen. is proposed as a replacement for Neothereva Kröber sensu Lyneborg (1976). Neothereva Kröber, 1912, is placed in new synonymy with Thereva Latreille, 1796, as the consequence of an overlooked designation of a type-species for Neothereva Kröber, 1912, by Kröber (1935). Neotherevella is fully described. Five specific names are placed in new combination with Neotherevella, which is known from Namibia, Mauritania, Algeria, Sudan, Egypt, Israel, Uzbechistan and Mongolia. It is demonstrated that two species described in combination with Neothereva by Zaitzev (1970) do not belong to Neotherevella.

Iljinskaea is described as a new monospecific genus based on a critical evaluation of morphology and in light of the extensive molecular phylogenetic data. The new combination I. planisiliqua is proposed, and the distinguishing characters separating the new genus from Conringia are discussed. The new tribal assignment of Iljinskaea in the Isatideae is discussed and compared with the previous placement in the Conringieae.
