A synopsis of the pin-hole borers of Thailand (Coleoptera: Curculionidae: Platypodinae)

The bark and ambrosia beetles of Bhutan (Coleoptera: Curculionidae: Scolytinae and Platypodinae): a synopsis with three new species of Scolytinae

The present state of knowledge of the bark and ambrosia beetles of Bhutan is summarised as a basis for future studies of the fauna, and its economic importance in forestry, timber production and crop tree plantations. We describe three new species of Scolytinae: Cyclorhipidion druk Smith & Beaver, Euwallacea insolitus Smith & Beaver, and Xylosandrus geduensis Smith & Beaver. Thirty-four species of Scolytinae, and 13 species of Platypodinae are now known to occur in Bhutan, of which 14 species of Scolytinae, including the three new species, and four species of Platypodinae, are recorded for the first time. A checklist of the fauna is provided, with information on local and world distribution, host trees and biology, and taxonomy.  

A new species, a new combination, and a new record of Crossotarsus Chapuis, 1865 (Coleoptera, Curculionidae, Platypodinae) from China

This study describes a new species, Crossotarsusbeaveri Lai & Wang, sp. nov., designates a new combination, C.brevis (Browne, 1975, comb. nov. from Platypus Herbst, 1793), and notes a new record, C.emorsus Beeson, 1937, from China. Genetic data from four genes indicate that the new species and C.brevis form a clade clustered with other Crossotarsus species. Molecular phylogeny and morphological characters support their taxonomic placement.
