A new species of Dryophthorus and two new species of Stenommatus (Coleoptera: Dryophthoridae ) are described from Dominican amber. Dryophthorus microtremus n. sp. is characterised by monochrome dorsal scales, nearly parallel sides of the pronotum, wide elytral intervals and the elytral apex only slightly narrowed. Stenommatus tanyrhinus n. sp. is characterised by an elongate rostrum 4.5 times as long as wide in the middle. S. leptorhinus is characterised by small body size, a thin rostrum 3.0 times as long as wide in the middle, wide striae and a narrow prosternal process. This brings the total number of species of Dryophthorini in Dominican amber to five, which is more than half the number of extant species. http://www.zoobank.org/urn:lsid:zoobank.org:pub:4329D0DA-57BD-4CEA-9464-ABD5D1577FC9 相似文献

A new genus and species, Espanoderus barbarae gen. et sp. nov., belonging to the family Tanyderidae (Diptera, Nematocera), is described from Lower Cretaceous amber of Spain (Álava amber). The new genus is the smallest member of Tanyderinae and the first member of the family from the Álava amber. The position of the new genus in a phylogenetic tree of Tanyderidae is presented. http://zoobank.org/urn:lsid:zoobank.org:pub:EC3284BA-C07F-48AC-8AF5-4F9D2EF4EA6C 相似文献

Pulchellaranea pedunculatan. gen., n. sp. (Araneae: Araneidae), a new genus of orb web spiders, is described from Cenozoic Dominican amber. Fossil representatives of the Araneidae are uncommon, even though the family is widely distributed today. An arboreal ant adjacent to Pulchellaranea pedunculata indicates the likely habit of the fossil spider in the Dominican amber forest. The encounter with the ant may have resulted in both specimens falling into fresh resin on the trunk of the Algarroba tree. A key to araneid spiders reported in Dominican amber is provided. http://www.zoobank.org/urn:lsid:zoobank.org:pub:D7F92A3C-46BB-48C0-9BA1-0496038F04A5 相似文献

A new genus and species of belid weevils, Pleurambus strongylus Poinar and Legalov, n. gen., n. sp. (Coleoptera: Belidae) in the tribe Allocorynini is described from Dominican amber. Belid fossils are quite rare and the new species is the first fossil member of the family from the Neotropics. This discovery suggests that belid diversity in Hispaniola during the Tertiary was higher than at present since no extant belids have been reported from the West Indies. http://www.zoobank.org/urn:lsid:zoobank.org:pub:DF79FF39-634D-4BD7-AD0B-F5FB3BBE1081 相似文献
