Crickets (Orthoptera: Grylloidea) are a highly diverse and successful group that due to their chirping are often heard more often than they are seen. Their omnivorous diet allows them to exist in a variety of terrestrial habitats around the world. In some environments, cricket populations can build up and become plagues, resulting in significant damage to seedling crops. A new genus and species of cricket, Pherodactylus micromorphus gen. et sp. nov. (Orthoptera: Gryllidae) is described from mid-Cretaceous Myanmar amber. The new genus is characterized by the following features: head without prominent bristles, pronotum longer than wide, middle of pronotal disk with two distinct large dark “eyespots”, fore leg robust and 3 apical spurs arranged on inner side of fore leg tibia. Shed portions of a lizard skin adjacent to the specimen reveal possible evidence of attempted predation.

One new tropiduchid genus, Neotaxilanoides gen. n., with type species Neotaxilanoides orientalis sp. n., is described and illustrated from China. The new genus is externally similar to Neotaxilana Synave 1979, but can be distinguished from the latter by the differences in the head structure, forewing venation and male genitalia. A checklist along with a revised key to the known genera in the tribe is provided.

Renefouqueosis peruviensis gen. et sp. nov., a new tenebrionid genus and species of the tribe Stenosini (subtribe Stenosina) is described from the arid mountains of Northern Peru. Including the new genus Renefouqueosis gen. nov., the tribe Stenosini now includes 40 valid genera of which nine are from the New World. The genera are placed in six subtribes (two worldwide, two New World and two Old World). Type species and subtribal assignment for each genus is presented. Notes on the placement of the genera Anchomma LeConte, 1858 and Fitzsimonsium Koch, 1962 are given. The proper placement of these genera is uncertain. Because of numerous morphological similarities to the Stenosini, we have decided to place these in a key to the world genera of Stenosini, which we provide.

AbstractThe Angosto de Lampazar, a classic locality for the study of lower Paleozoic successions in the Cordillera Oriental, NW Argentina, has yielded a late Cambrian relatively diverse, lingulate brachiopod fauna. Sandy lenses with calcareous cement from the uppermost levels of the Lampazar Formation have yielded abundant remains of articulate and phosphatic brachiopods. Among the latter, the new speciesEurytreta harringtoniMergl and Herrera,Lingulella?melonicaMergl and Herrera,Libecoviella lenticularisMergl and Herrera, andSchizambon cardonalisMergl and Herrera, as well as the new genus and speciesSaltaia lampazarensisMergl and Herrera are formally introduced. Trilobites and conodonts from the same horizons characterize theCordylodus proavusZone, allowing a correlation with Stage 10 of the Furongian Series. Although the information on lingulate brachiopods from theC.proavusZone is scarce across the world, the composition of the studied association displays a relationship with coeval and slightly younger faunas of Utah and Kazakhstan. The Argentine brachiopods, the first described from the late Cambrian Proto-Andean margin of Gondwana, are more closely related to temperate Laurentian faunas than to those from the high latitude North African margin of Gondwana.

Abstract Enigmatic and rarely collected, ambush bugs of the tribe Macrocephalini (Heteroptera: Reduviidae: Phymatinae) encompass a diverse group of predatory bugs armed with subchelate raptorial forelegs, a greatly enlarged scutellum, and elongate head. Macrocephalini is the most specious of the four tribes of ambush bugs, consisting of 20 genera and 154 species. They are represented in the Caribbean by several remarkable taxa that bear foretarsi, a trait unassociated with macrocephalines found elsewhere in the world. I here describe a new genus and species of Macrocephalini, Capricephala chiaroscuro gen. et sp. nov., native to the island of Hispaniola and one that bears striking differences to other phymatines known from that region.

Problematic sclerites are common in Cambrian rocks around the world, but much less so in those of the Ordovician. Eurytholia prattensis new genus and species and E. elibata new species, described herein, are rare but widely distributed faunal elements in a narrow stratigraphical interval (Pygodus serra and P. anserinus conodont biozones) within Ordovician beds in an area bordering Iapetus (South Wales, UK; Alabama, USA; Dalarna, Sweden; and North Estonia). Specimens are minute plates (usually less than 1 mm wide), transversely ovoid, and hollow. They are not closely comparable with any previously described fossils. Eurytholia plates are interpreted as dorsal dermal sclerites from an animal of uncertain affinities. The scleritome is provisionally reconstructed as ovoid in form, with sclerites arranged in sub-longitudinal rows.

Birjandtrombella farniae Noei gen. et sp. nov. (Acari: Trombidiformes: Prostigmata: Trombellidae) is described and illustrated from larvae ectoparasitic on moths (Lepidoptera: Crambidae, Noctuidae, Pyralidae), from Birjand city, South Khorasan province, Iran. Moth families Crambidae and Pyralidae are recorded as the host of Trombellidae larvae, for the first time. Also, a key to genera of Trombellinae Thor, 1935 of the world (larva) is presented.

The largest documented cimolestid, Alveugena carbonensis new genus and species, is both morphologically and temporally intermediate between small, early cimolestids (such as Procerberus and Cimolestes) and the earliest documented conoryctid taeniodont Onychodectes tisonensis; this represents a transition between the suborders Didelphodonta and Taeniodonta. Diagnosis and description of A. carbonensis is based upon a partial skull and two isolated upper molars recovered from fluvial sandstones at UW locality V-91005, in upper parts of the Ferris Formation, western Hanna Basin, Wyoming. An earliest middle Puercan age for UW locality V-91005 is based upon: presence of taxa that are morphologically intermediate between characteristic early and middle Puercan species; presence of a species of Ectoconus morphologically more primitive than Ectoconus ditrigonus; and co-occurrence of taxa characteristic of Pu1 and Pu2 stratigraphically below and above it. Morphologic trends in evolution of the upper dentition of cimolestids reflect a relative broadening of the crown. A trend toward increasing body size amongst Puercan cimolestids appears to have coincided with a change from a carnivorous (or perhaps insectivorous) to an omnivorous diet, suggested by increased grinding function of the cheek teeth. Cladistic analyses support A. carbonensis as the sister group to O. tisonensis. No known autapomorphies preclude A. carbonensis from having been a plausible ancestor to O. tisonensis.

AbstractA new genus and species of mites of the family Caraboacaridae (Acari: Heterostigmata),Intercaraboacarus clivinusKatlav and Hajiqanbarnew genus,new species, associated withClivina ypsilonDejean, 1829 (Coleoptera: Carabidae), is described from Iran. It is the third genus of the family Caraboacaridae in the world. The new genus represents a combination of shared character states with the two previously described genera. An illustrated key to world genera of the family is provided. Differentiation of the new genus from other genera and distribution and host range of all known genera and species of the family are discussed.
