The Megophthalmidia (Diptera,Mycetophilidae) of North America including eight new species

Megophthalmidia Dziedzicki is a small leiine genus (Mycetophilidae) with seven species described from the Neotropics and ten species from the Palearctic region. Two species of Megophthalmidia have been reported for North America. Recent collecting of Mycetophilidae in California and Arizona, however, shows current North American diversity of Megophthalmidia is at least on par to other regions of the world. Eight new species of Megophthalmidia are described here, increasing the number of Nearctic Megophthalmidia species to nine. Included is a particularly atypical member of the genus, M. saskia sp. n., which expands the genus concept of Megophthalmidia. Of the two species previously recorded for North America, only one actually belongs in the genus. Megophthalmidia occidentalis Johannsen, is fully described and illustrated. The other named species, M. marceda (Sherman) is illustrated and transferred to the genus Ectrepesthoneura Enderlein. A lectotype is designated for this species. A key to the species of Megophthalmidia of North America is provided. The biology of these flies is not yet known. Three of the new Megophthalmidia species – M. lenimenta, M. misericordia, and M. radiata – are only known to occur within small protected areas within the California State Park and UC Natural Reserve systems.     

A new genus and species of Urodidae (Lepidoptera: Urodoidea) from Sri Lanka

A new genus of Urodidae, Geoesthia gen. nov., is described with the type species, Geoesthia ceylonica sp. nov. from Sri Lanka. This is the second urodid genus from the Oriental Region. The new species is the only urodid recorded from Sri Lanka. The new genus is distinguished from all the known genera within Urodidae by a combination of four characteristics: the lack of scale tufts on the labial palpi; the absence of raised scales of two subbasal spots on the forewings; the presence of M-stem on the hindwings; and the female corpus bursae bearing five signa. Key to the genera and species of Urodidae from the Oriental Region is provided.     

Sucrea (Poaceae: Bambusoideae), a new genus from Brazil

Sucrea, a new genus of herbaceous bambusoid grasses is based on the newly described species,S. monophylla. Also belonging to this genus is another new species,S. maculata, and the taxon originally namedOlyra sampaiana. The new genus is contrasted in a key with others of its tribe Olyreae, and a key is given to its three species.     

Description of Muscotabanus gen. nov. and Muscotabanus rafaeli sp. nov. (Diptera: Tabanidae: Diachlorini) from Amazon Basin,Brazil

A new genus of Tabanidae mimetic of flies is described: Muscotabanus new genus, Muscotabanus rafaeli new species, based on 12 females collected in the state of Amazonas, Brazil. It is presented a discussion for separating the new genus from Diachlorini species which resemblance with sarcophagids flies. It is characterised by striped thorax, banded abdomen, long slender palpus subequal antenna length, labella predominantly membranous, except for a narrow sclerotised plate, basicosta bare, wing hyaline and stigma brown.     

Family Linoproductidae Stehli, (Brachiopoda) from the Upper Moscovian of the Middle Carboniferous of the Moscow Region

Species from the family Linoproductidae sensu str. from the Podolskian-Myachkovian deposits of the Moscow Region are revised and redescribed. The peculiarities of the arrangement of spines on the ventral valve are used as a basis for a new taxonomic structure. A new genus Linipalus, which appeared in the Podolskian time and was widespread in the Late Carboniferous and Early Permian, is established. Three new species of the genus Linispinus Lazarev, 2006, and one new species of the genus Linipalus gen. nov. are described.     

New taxa of compositae (Eupatorieae) from Brazil

A new genus and speciesMonogereion carajensis and a new species ofAgeratum, A. glomemtum, are described from Para, Brazil. The relationships of the new genus and species are discussed.     

A new genus Heppneralis Park of Lecithoceridae (Lepidoptera: Gelechioidea) from Is. Sulawesi,Indonesia, with descriptions of two new species

A new genus, Heppneralis Park, gen. nov., of the subfamily Torodorinae, is described based on the type species, H. decorella sp. nov., and an additional new species, H. dumogaensis sp. nov., from Is. Sulawesi, Indonesia is described. The new genus is distinguished from all known genera of the subfamily by unique wing color markings on both wings, with R₅ and M₂ absent in the forewing and M₂ absent in the hindwing.     

A New Species of Skin-Feeding Caecilian and the First Report of Reproductive Mode in Microcaecilia (Amphibia: Gymnophiona: Siphonopidae)

A new species of siphonopid caecilian, Microcaecilia dermatophaga sp. nov., is described based on nine specimens from French Guiana. The new species is the first new caecilian to be described from French Guiana for more than 150 years. It differs from all other Microcaecilia in having fewer secondary annular grooves and/or in lacking a transverse groove on the dorsum of the first collar. Observations of oviparity and of extended parental care in M. dermatophaga are the first reproductive mode data for any species of the genus. Microcaecilia dermatophaga is the third species, and represents the third genus, for which there has been direct observation of young animals feeding on the skin of their attending mother. The species is named for this maternal dermatophagy, which is hypothesised to be characteristic of the Siphonopidae.     

New species and records of Charisius Champion from Mexico and Central America (Coleoptera,Tenebrionidae, Alleculinae)

The species of the genus Charisius Champion, from Mexico and Central America are reviewed. The flightless genus Narses Champion, with one included species, N. subalatus Champion, is placed in synonymy with the genus Charisius. Four new species are described and illustrated, C. granulatus and C. punctatus (from Guatemala) and C. apterus and C. howdenorum (from Mexico). Charisius subalatus (Champion) is redescribed and illustrated. The species C. interstitialis Champion is placed in synonymy with C. zunilensis Champion. The genus is redescribed to include the four new species and N. subalatus. New distributional records are presented for all other species of the genus and a revised key is presented for identification of all the species of the genus.     

Descriptions of a new Brazilian Tacora species and the female of Tacora saturata, and a key to the species of the genus (Insecta, Hemiptera, Cicadellidae, Cicadellini)

Tacora johanni, a new species from Rondônia State, North Brazil, is described and illustrated. The new species can be recognized by the male genital features, especially the subgenital plates with the basal half distinctly expanded and with outer lateral margin round, the long and slender preapical pygofer process, and the styles with apical half strongly curved. Also, the genus is recorded for the first time from Venezuela, based on specimens of Tacora saturata Young, 1977, while the female of this species (here described in detail for the first time) shows two unusual features of the genitalia. A key to males of all known Tacora species and a map showing the known distribution of the genus are provided.
