A new weevil genus of the tribe Metrioxenini (Coleoptera: Belidae) in Eocene Baltic amber

A new genus, Succinometrioxena n. gen., and a new species, S. poinari n. sp. (Metrioxenini: Oxycoryninae), are described from Baltic amber. This new genus resembles the recent genus Wallacexena Legalov, 2009 but differs from it by the frons with horn-like tubercles on either side, the absence of a middle pronotal carina, teeth on the side of the pronotum, the anterior margin of the pronotum lacking teeth and two long carinae on the elytra. From the fossil genus Paltorhynchus Scudder, 1893 the present fossil differs by possessing a frons with horn-like tubercles on either side, the absence of a middle pronotal carina, teeth on the sides of the pronotum, two long carinae on the elytra and short temples. From the fossil genus Archimetrioxena Voss, 1953, the new genus differs by the frons with horn-like tubercles on either side, the absence of the two truncated elytral carinae, the sides of the pronotum with teeth, short temples and a larger body size.     

New species of the genus Glaesotropis (Insecta: Coleoptera: Anthribidae) from Rovno amber

A new species of the fungus weevil genus Glaesotropis is described from the Late Eocene Rovno amber. G. diadiasashai sp. nov. differs from G. weitschati and G. minor described from Baltic amber in having a longer rostrum and in the structure of its antennae, with the third and fourth antennomeres being longer than the first and second ones. Additionally, the new species differs from G. weitschati in being smaller, in having unswollen frons, and weakly and smoothly concave elytral margin near hind coxae. The new species also differs from G. minor in having an uninterrupted posterior transverse carina on the pronotum, elytra less convex longitudinally, and a slightly broadened rostrum at the attachment of antennae.     

New species of chalcidoid wasps of the family Eurytomidae (Hymenoptera,Chalcidoidea) from arid Palaearctic regions

Five new species of chalcidoid wasps of the family Eurytomidae are described: four from Israel and one from Kazakhstan. Tetramesa pavliceki Zerova, sp. n. (cylindrica species group) is closely related to T. scheppugi Schlecht., but differs in the more elongate flagellar segments, longer genae, and smooth metasomal tergites. Eurytoma nevoi Zerova, sp. n. is similar to E. sabulosa Erd. and E. bicolorata Zer. (phragmiticola species group), differs from these species in the longer marginal vein, punctate propodeum, and longer flagellar segments. E. oreni Zerova, sp. n. belongs to the fumipennis species group. It is closely related to E. monticola Zer., but differs in the more convex scape, longer postmarginal vein, and yellow legs. E. simutniki Zerova, sp. n. belongs to the robusta species-group. It resembles E. heriadi Zer., but differs in the longer flagellar segments of the female and in the shorter postmarginal vein. Nikanoria mamayevi Zerova, sp. n. is similar to N. stigma Zer., but differs in the more elongate metasoma, longer flagellar segments of both sexes, and larger yellow spots on the pronotum.     

A new species of Triatominae from Tamil Nadu, India

Abstract A new species of the genus Linshcosteus Distant, 1904 (Hemiptera: Reduviidae: Triatominae) is described from specimens collected near Kalakkadu, Tamil Nadu state, southern India. Specimens were found in deep crevices between rocks, in a region of semi‐arid scrub jungle. The distinctiveness of the new species was demonstrated by a morphometric analysis including the five previously described species of Linshcosteus, all from India. Nine measurements of the head were used in an isometric size‐free principal component analysis. In terms of discrete morphology the new species, Linshcosteus karupus sp.n. Galvão, Patterson, Rocha & Jurberg differs from the most similar one, L. kali Lent & Wygodzinsky, 1979 , by its very prominent anterolateral projections of the pronotum, by the length to width ratio of the pronotum, by the pilosity of the head and several other characters, including phallic structures. A revised key is presented for the six species of the genus.     

New and little known weevils (Coleoptera: Curculionoidea) from the Paleocene of Menat (France)

Two new genera Petropsis gen. n., and Menatorhis gen. n., and two species, Petropsis rostrata gen. et sp. n. (Ithyceridae) and Perapion menatensis sp. n. (Brentidae), are described from the Paleocene of Menat (France). Petropsis rostrata gen. et sp. n. is similar to Cretocar luzzii Gratshev et Zherikhin (2000) but differs from it in the comparatively short ventrites 1 and 2, almost straight and not dilated metatibiae, short precoxal portion of the prosternum, slightly convex elytra and antennae inserted more closely to the middle of the rostrum. Perapion menatensis sp. n. is similar to Perapion antiquum (Gyllenhal, 1833) but differs from it in the straight rostrum, sparser and finer punctures of the pronotum, and somewhat larger body. The families Ithyceridae and Brentidae are recorded for the first time in the Paleocene of Menat. The systematic positions of Balaninus elegans Piton (1940) (type species of Menatorhis gen. n.) and Hipporhinus ventricosus Piton (1940) are discussed.     

A new species of the genus <Emphasis Type="Italic">Anthonomus</Emphasis> Germar (Curculionidae) in Mexican amber

A new species, Anthonomus dilatofemurus Poinar et Legalov, sp. nov., from Mexican amber is described and illustrated. The new species is close to A. cruraluma Poinar et Legalov and differs from it in the wider elytra with narrow striae and strongly swollen pro- and metafemora. It differs from A. browni Poinar et Legalov in the wide and short elytra, shorter and thicker weakly curved rostrum, and strongly swollen metafemur. It is distinguished from A. camoiranensis Clark by the metatitibia with uncus and from A. sulcatus Kirsch by the protibia with uncus, metatibia with ventral fringe of medium scales, narrower elongate pronotum, weakly convex elytra and weakly curved rostrum.     

Revision of the genus Adorodocia Brenske 1893 (Coleoptera: Scarabaeoidea: Rutelinae: Adoretini) endemic to Madagascar

Summary. The Adoretini of the Malagasy endemic genus Adorodocia Brenske 1893 is revised. Fourteen new species and one new subspecies are described and compared with their most closely related species: A. constricta n. sp., A. cuccodoroi n. sp., A. flava n. sp., A. liliae n. sp., A. marginata n. sp., A. peyrierasi n. sp., A. pseudoconstricta n. sp., A. pseudoflava n. sp., A. pseudostrigata n. sp., A. recta n. sp., A. robusta n. sp., A. sogai n. sp., A. vadoni n. sp., A. viettei n. sp. and A. vittaticollis flavipes n. ssp. The synonymy between Adoretus strigatus Waterhouse 1878, and Pseudadorodocia aenigma Arrow 1901, is confirmed. Thus, based on the results of this study, the genus Adorodocia includes 16 species, and one of them is represented by two subspecies. Diagnostic characters to separate the species in the genus deal mostly with the shape of parameres, color of body and legs, shape of pronotum and female eighth tergite, setation of pronotum and elytra. Key to species, diagnoses and distribution for each species are provided. Endophallus and female genitalia are illustrated for the first time for this genus.     

Multivariate discrimination among cryptic species of the mite genus Chaetodactylus (Acari: Chaetodactylidae) associated with bees of the genus Lithurgus (Hymenoptera: Megachilidae) in North America

Twenty-seven morphological characters from 111 heteromorphic deutonymphs of the mite genus Chaetodactylus Rondani (Acari: Chaetodactylidae) were analyzed. The mites were collected from four species of bees of the genus Lithurgus Berthold (Hymenoptera: Megachilidae) in continental North America. Principal component and canonical variates analyses on Darroch and Mosimann shape and size-and-shape variables revealed the presence of three cryptic species. Chaetodactylus gibbosi sp. n. (Florida) is geographically isolated from C. lithurgi sp. n. distributed in Texas, New Mexico, Arizona, Colorado, and Idaho. Sympatric C. lithurgi and C. abditus sp. n. (USA: Arizona, Mexico: Socorro Is.) are seasonally isolated in Arizona. Chaetodactylus gibbosi is associated with a single bee species, Lithurgus gibbosus Smith in Florida. The host range of C. lithurgi includes bees flying predominantly in the spring: L. apicalis Cresson, L. littoralis Cockerell, and western L. gibbosus. Chaetodactylus abditus sp. n. is associated with L. planifrons Friese and L. echinocacti Cockerell, flying predominantly in the fall in Arizona. No distinct groups separated by geographic locality or size were detected in any species. A six-variable model developed by the canonical variates analysis and estimated using jackknife resampling and external validation (n=100) is capable of classifying the three species with 100% accuracy. Factors that influenced speciation of cryptic species of Chaetodactylus associated with Lithurgus are discussed. Based on morphological and geographical data and data on mite associates, the western and eastern populations of the bee L. gibbosus are distinct. Therefore, the taxonomic status of L. gibbosus s. lat. should be reevaluated.     

Allolarinus,a new genus and species of Lixini (Coleoptera: Curculionidae: Lixinae) from Congo

A new weevil genus, Allolarinus n. gen., with type species, Allolarinus demeyeri n. sp., is described from Congo in the tribe Lixini. The illustrations and diagnostic characteristics of this genus have been presented in a table and figure plates. This new genus is related to Larinus Dejean in terms of the type of elytra and general shape of the prothorax but clearly differs from Larinus with respect to its tooth-bearing femora and granulose pronotum. The trapezoidal short-neck prothorax and general shape of the elytra of this new genus are similar to those of Larinus; the granulose pronotum to that of Lixomorphus Faust; the dentate femora to that of Holcolixus Voss, Erilixus Voss, and Sublarinus Petri; while the existing cubito-anal vein on metathoracic wings to those of Allolixus Voss.     

A NEW BANGIOPHYCIDEAN ALGA FROM ALABAMA1

A new species of red algae, Boldia angustata sp. nov., was discovered near Tuscaloosa, Alabama, during the spring of 1968. It differs significantly from the only previously described species, Boldia erythrosiphon Herndon, in length and width of young and mature thalli, cell size, shape of nuclei in first-order cells, shape of intercalary filaments, morphology of filaments derived from monospores, ontogenetic development of erect plants, morphology of the basal system, and regularity of first-order cells.     

The oldest genus of the subfamily Sagrinae (Coleoptera: Chrysomelidae) from the Paleocene of Menat (France)

The new oldest representative of the subfamily Sagrinae, Gallopsis perita gen. et sp. n. from the Paleocene of Menat (France), is described and illustrated. It is distinguished from the genus Neodiaphanops Blackburn, 1899 by the metafemora without teeth, wider pronotum, weakly widened tibiae, bilobed tarsomere 2, subparallel elytra, and narrower metanepisterna. It differs from the Australian genus Carpophagus Macleay, 1826 in the head without rostrum, weakly widened metafemora without teeth, and gently sculptured pronotum and elytra. The new genus differs from the Eocene genus Eosagra Haupt, 1950 in the longer antennomere 2, wider pronotum and elytra, dense and diffuse elytral puncturation, and weakly inflated metafemora.     

<Emphasis Type="Italic">Tibouchina xochiatencana</Emphasis> (Melastomataceae), una nueva especie de la Sierra Madre del Sur de Guerrero,México

Tibouchina xochiatencana, a new species of Melastomataceae collected near Xochiatenco, municipality of Malinaltepec, in the Sierra Madre del Sur of Guerrero, is described and illustrated. This species is part of an informal group of Mexican species with large, strongly dimorphic stamens. Its distant relatives are Tibouchina araneicalyx and T. durangensis, both of which have bractlets and calyx lobes that are adaxially glabrous, and short, appressed hypanthial trichomes.     

A remarkable new genus of Procercopidae (Hemiptera: Cercopoidea) from the Middle Jurassic of China

Jurocercopis grandis, a new genus and species belonging to Procercopidae (Hemiptera: Cercopoidea), is described, based on seven specimens from the Middle Jurassic of Daohugou, China. It differs distinctly from other genera as follows: body and wings obviously large; pronotum with posterior margin straight; tegmen with costal margin convex at about basal 0.4 wing length; hind basitarsomere with a row of apical small teeth.     

A new species, <Emphasis Type="Italic">Orphnus drumonti</Emphasis> sp. n. (Coleoptera,Scarabaeidae), from the Democratic Republic of Congo

Three new scarab-beetle species are described. Aphodius moronensis sp. n. (northern Mongolia) and A. kozlovi sp. n (eastern Tibet) with modified spurs on fore tibiae in males are placed in the falcispinis group of the subgenus Agolius but are similar to the grafi group of the subgenus Chilothorax in the shape of parameres and elytral pattern. The new species differ from A. falcispinis in the shape of the spur; A. moronensis sp. n. also differs in the shape of the body and parameres. Orphnus transvaalensis sp. n. is the second apterous Orphnus species found in Southern Africa. It differs from the closely related O. harrisoni in the shape of parameres, position of the hornlike clypeal process, and in a smaller body size.
