An illustrated key to seventeen species of Bostrichidae recorded in association with rubberwood in Th ailand is provided. A checklist is given of nine species infesting rubberwood sawn timber in sawmills in southern Th ailand, with information on distribution, host trees and biology. Th ree species are recorded for the fi rst time from Th ailand: Cephalotoma tonkinea Lesne, Lyctoxylon dentatum (Pascoe), and Minthea reticulata Lesne.
An annotated synopsis of Iranian Bostrichidae (Coleoptera: Bostrichoidea) is provided as a basis for future studies, with notes on distribution, host plants, biology and economic importance. In total, 31 species from 18 genera and 4 subfamilies (Bostrichinae, Dinoderinae, Lyctinae and Psoinae) are listed from Iran. Sinoxylon anale Lesne, 1897, Sinoxylon perforans (Schrank, 1789, Stephanopachys linearis (Kugelann, 1792) and Xylopertha retusa (Olivier, 1790) are new records for Iran.
Abstract.A new genus and species of bostrichid beetle, Octomeristes gen. nov. and Octomeristes pusillus gen. et sp. nov., in the tribe Xyloperthini is described from litchi (Litchi chinensis Sonn.) wood in Thailand. The genus is compared to Octodesmus Lesne, 1901, the only other xyloperthine genus with eight-segmented antennae, and to the xyloperthine genera, Xylion Lesne, 1901, Xylionulus Lesne, 1901 and Xylobosca Lesne, 1901 (Lesne, 1932). A key is provided to the species of Octodesmus and Octomeristes gen. nov.
Thirty-three species belonging to the bostrichid subfamilies Lyctinae and Dinoderinae were examined by low vacuum ESEM without sputtering. Eight types of microsculpture, five types of hair insertion, and 14 types of hair were found on the elytral disc and declivity. The different types of microstructure are described and illustrated with ESEM photos of each type. Surface microstructures provide additional taxonomically useful characters which can help to distinguish easily confused species. The study also showed that specimens can be examined under ESEM without any damage.
This paper reviews the genera Xylothrips Lesne, 1901 and Calophagus Lesne, 1902, and their species, and proposes that Calophagus should be reinstated as a full genus from a subgenus of Xylothrips (contra Borowski & Węgrzynowicz 2019). The genera and their included species are diagnosed and redescribed, and a summary of information on the distribution and biology of all species is provided. The importance of characters of the antennal club and pronotum in separating the two genera is stressed. A key to the two genera and the two species of Xylothrips is provided.
We provide an annotated synopsis of all the Eurasian Lyctinae with a key to all three tribes, seven genera and thirty-eight species. We provide for each species a summary of what is currently known about its taxonomic status, distribution, host plants, biology, and economic importance as a baseline for future studies of the fauna, particularly in relation to the growing importance of lyctines as economically important pests in the region.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
