Vetufebrus ovatus n. gen., n. sp (Haemospororida: Plasmodiidae) vectored by a streblid bat fly (Diptera: Streblidae) in Dominican amber

Creator:: Poinar, George O., Jr.
Abstract:: Background: Both sexes of bat flies in the families Nycteribiidae and Streblidae (Diptera: Hippoboscoidea) reside in the hair or on the wing membranes of bats and feed on blood. Members of the Nycteribiidae transmit bat malaria globally however extant streblids have never been implemented as vectors of bat malaria. The...

Halophilanema prolata n. gen., n. sp. (Nematoda: Allantonematidae), a parasite of the intertidal bug, Saldula laticollis (Reuter)(Hemiptera: Saldidae) on the Oregon coast

Creator:: Poinar, George O., Jr.
Abstract:: Background: It is rare to find terrestrial nematode lineages parasitizing arthropods inhabiting the intertidal or littoral zone of the oceans. During an ecological study along the Oregon dunes, an allantonematid nematode (Tylenchomorpha: Allantonematidae) was discovered parasitizing the intertidal shore bug, Saldula laticollis (Reuter) (Hemiptera: Saldidae). This shore bug is adapted...

New fossil nematodes in Dominican and Baltic amber

Creator:: Poinar, George O., Jr.
Abstract:: Four new species of fossil mermithids (Nematoda: Mermithidae) are described from amber: Heydenius arachnius n. sp. from a spider (Arachnida: Araneae) in Dominican amber, Heydenius phasmatophilus n. sp., from a walking stick (Phasmatodea: Phasmatidae) in Baltic amber, Heydenius podenasae n. sp. from a moth (Lepidoptera) in Baltic amber and Heydenius...

Silica bodies in the Early Cretaceous Programinis laminatus (Angiospermae: Poales)

Creator:: Poinar, George, Jr.
Abstract:: Silica bodies in short cell epidermal leaf cells of the Early Cretaceous Programinis laminatus (Poales) in Burmese amber are characterized. The great majority are rondels and elongated quadrates aligned horizontally in relation to the leaf axis. Rondel types include circular, elliptical, oblong, long and short forms. Quadrate types include short...

A primitive triatomine bug, Paleotriatoma metaxytaxa gen. et sp. nov. (Hemiptera: Reduviidae: Triatominae), in mid-Cretaceous amber from northern Myanmar

Creator:: Poinar, George, Jr.
Abstract:: The present study describes a primitive kissing bug (Hemiptera: Reduviidae: Triatominae) in mid-Cretaceous amber from northern Myanmar. The fossil, which is described as Paleotriatoma metaxytaxa gen. et sp. nov., contains a predominance of features of the Triatominae as well as some characters of the Reduviinae and is considered an intermediate...

First record of the genus Baris Germar, 1817 (Coleoptera: Curculionidae), in Dominican amber

Creator:: Poinar, George O., Jr. and Legalov, A. A.
Abstract:: A new weevil species – Baris grossacavis Poinar and Legalov, sp. nov. (Coleoptera: Curculionidae) – is described from Dominican amber. The new species is close to Baris rubripes Casey, 1892, but differs by possessing large punctures over much of its body, including the pronotum; elytral intervals with rows of narrow...

A mid-Cretaceous ambrosia fungus, Paleoambrosia entomophila gen. nov. et sp. nov. (Ascomycota: Ophiostomatales) in Burmese (Myanmar) amber, and evidence for a femoral mycangium

Creator:: Poinar, George O., Jr. and Vega, Fernando E.
Abstract:: An ambrosia fungus is described from filamentous sporodochia adjacent to a wood-boring ambrosia beetle (Coleoptera: Curculionidae: Platypodinae) in mid-Cretaceous Burmese amber. Yeast-like propagules and hyphal fragments of Paleoambrosia entomophila gen. nov. et sp. nov. occur in glandular sac mycangia located inside the femur of the beetle. This is the first...

Parasitylenchus bifurcatus n. sp. (Tylenchida: Allantonematidae) parasitizing Harmonia axyridis (Coleoptera: Coccinellidae)

Creator:: Poinar, George O., Jr. and Steenberg, Tove
Abstract:: Background: The harlequin ladybird, Harmonia axyridis Pallas (Coleoptera: Coccinellidae) is native to central and eastern Asia and was purposely introduced into Europe to control aphids. While it proved to be a good biological control agent, its rapid spread and buildup of large populations made it a nuisance, since it overwinters...

Tripius gyraloura n. sp. (Aphelenchoidea: Sphaerulariidae) parasitic in the gall midge Lasioptera donacis Coutin (Diptera: Cecidomyiidae)

Creator:: Poinar, George, Jr. and Thomas, Donald B.
Abstract:: A new nematode, Tripius gyraloura n. sp., is described from the arundo gall midge, Lasioptera donacis Coutin (Diptera: Cecidomyiidae). This gall midge is being considered as a biological control agent for use in North America against the introduced giant reed Arundo donax (L.) (Poaceae: Cyperales). Thus the present study was...

First record of the genus Pseudopilolabus Legalov, 2003 (Coleoptera: Attelabidae) in Dominican amber

Creator:: Poinar, George O., Jr., Brown, A. E., and Legalov, A. A.
Abstract:: A new weevil species (urn:lsid:zoobank.org: act:2D5E9E4A-A250-4D0A-AF69-CF4753436686), Pseudopilolabus othnius Poinar, Brown and Legalov, sp. nov. (Coleoptera: Attelabidae), is described from Dominican amber. The new species is close to the extant P. viridanus (Gyllenhal, 1839) and P. splendens (Gyllenhal, 1839) but differs by having a bronzed body, narrower and more convex elytral...
