We provide an annotated checklist of species of bark and ambrosia beetles (Curculionidae: Platypodinae and Scolytinae) recorded from Iran, with information on distribution, host trees, biology and taxonomy. Two species of Platypodinae and 79 species of Scolytinae are recorded. Hypothenemus crudiae (Panzer, 1791), Scolytus koenigi Schevyrew, 1890 and Xy-leborus monographus Fabricius, 1792 are recorded for the first time from Iran. Previous records of three further species are considered dubious and require confirmation. © 2016 Magnolia Press.

The present state of knowledge of the scolytine ambrosia beetles of Thailand is summarised to provide a basis for future studies of the fauna and its economic importance in forestry, timber production and crop tree plantations. A checklist of the fauna is provided with information on local and world distribution, host trees, biology and taxonomy. Six faunal elements based on geographical distribution, and the host tree and altitudinal preferences of species are discussed. One hundred and sixty-one species are recorded from Thailand, 67 of them for the first time. The following new synonym is proposed: Euwallacea wallacei (Blandford) (= Xyleborus barbatomorphus Schedl n.syn.). The following new combinations are given: Ambrosiophilus cristatulus (Schedl), Ambrosiophilus latisulcatus (Eggers), Beaverium dihingensis (Eggers), Beaverium lantanae (Eggers) and Immanus desectus (Eggers) are transferred from their present position in Ambrosiodmus; Ancipitis depressus (Eggers) and Ancipitis punctatissimus (Eichhoff) are transferred from Leptoxyleborus; Cyclorhipidion armipenne (Schedl), Cyclorhipidion inarmatum (Eggers), Euwallacea semiermis (Schedl), Fortiborus macropterus (Schedl), Microperus nudibrevis (Schedl) and Wallacellus minutus (Blandford) are transferred from Xyleborus. © 2014 Magnolia Press.

The genus Diapus Chapuis was erected (Chapuis 1865) for four species of pinhole borer (Curculionidae: Platypodinae) from the Oriental region and New Guinea. It was distinguished from other platypodine genera primarily by the widely separated procoxae (Chapuis 1865). Hopkins (1914) designated Diapus quadrispinatus Chapuis, 1865 as the type species of the genus. The genus is currently placed in the platypodine tribe Tesserocerini, subtribe Diapodina (Alonso-Zarazaga & Lyal 2009). Only two genera are included in the Diapodina, Diapus and Genyocerus Motschulsky (Alonso-Zarazaga & Lyal 2009, Jordal 2015). Diapus is distinguished from Genyocerus by the following characters (Wood 1993, Beaver & Liu 2007): 1. In Diapus, the scutellum is narrower and more sunken, not flush with the elytral surface posteriorly as it is in Genyocerus. 2. The mycangial pores of Diapus are sometimes fused to form a transverse or crescentic bar on each side of the midline of the pronotum. This does not occur in Genyocerus. 3. The antennal club of Diapus sometimes has a median testaceous strip lacking sensillae on the anterior face. This strip is never present in Genyocerus. 4. The males of Diapus never possess a membranous extension of the apical margin of the fourth abdominal ventrite, present in some species of Genyocerus. 5. The females of Diapus often bear deciduous mandibular appendages, which are never present in Genyocerus (Beaver & Liu 2007).

Pristapenesia asiatica sp. nov. is described and illustrated from two female specimens collected in China and Thailand. This species is readily recognized by the absence of a tubular radial vein in the fore wings. A key to world fossil and living species of Pristapenesia is provided Copyright © 2011 Magnolia Press.


The four species included by Wood and Bright (1992) in the Palaeotropical scolytine genus Phloeosinopsioides Schedl are reviewed. The following new synonymy is proposed: Phloeosinopsioides formosanus (Schedl) (=Phloeosinopsis triseriata Schedl). A diagnosis of the genus and a key to the three species now included in the genus are provided. The taxonomy, distribution and biology of the species are briefly reviewed and some new records included. Copyright © 2011 - Magnolia Press.

The present state of knowledge of the pin-hole borers of Thailand is summarised to provide a basis for future studies of the fauna and its economic importance in forestry and timber production. A checklist of the fauna is provided with infor-mation on local and world distribution, host trees, biology and taxonomy. Six faunal elements based on geographical dis-tribution, and the host preferences of species are discussed. Ninety-two species have now been recorded in Thailand, of which forty-three are recorded here for the first time. Three species are endemic to Thailand. The following new combi-nations are given: Dinoplatypus piniperda (Schedl), Treptoplatypus fulgens (Schedl), both transferred from Platypus. Copyright © 2013 Magnolia Press.


Taxonomic confusion among the afrotropical scolytine genera Hapalogenius Hagedorn, Hylesinopsis Eggers and Rhopalopselion Hagedorn, and their synonyms is discussed with especial reference to the catalogues of Wood and Bright (1992), and Alonso-Zarazaga and Lyal (2009). A key is given to separate the three genera recognised, and the species considered to be included in each genus are listed. Hylesinopsis is resurrected from synonymy with Hapalogenius, and shown not to be closely related to it. Chilodendron Schedl is considered to be a synonym of Hylesinopsis and not of Xylechinus Chapuis. The following new synonymy is proposed at specific level: Hapalogenius africanus (Eggers) (= Hapalogenius lesnei Eggers, = Metahylesinus brincki Schedl); Hapalogenius fuscipennis (Chapuis) (= Hapalogenius bimaculatus Eggers); Hapalogenius oblongus (Eggers) (= Metahylesinus striatus Schedl); Hylesinopsis fasciata (Hagedorn) (= Kissophagus punctatus Eggers); Phrixosoma niger Eggers (= Hapalogenius niger Schedl). The following species are returned to Hylesinopsis from Hapalogenius to which they were transferred by Alonso-Zarazaga and Lyal (2009): Hylesinopsis alluaudi (Lepesme), H. angolensis (Schedl), H. arabiae (Schedl), H. atra (Nunberg), H. confuse (Eggers), H. decellei (Nunberg), H. dubia Eggers, H. emarginata (Nunberg), H. fasciata (Hagedorn), H. ficus (Schedl), H. granulata (Lepesme), H. hirsuta (Schedl), H. joveri (Schedl), H. pauliani (Lepesme), H. punctata (Eggers), H. saudiarabiae (Schedl). The following new combination is given: Hylesinopsis leprosula (Browne) from Cryphalus Erichson. New distributional records are given for some species. © Roger A. Beaver.


The eight species included by Wood and Bright (1992) in the Palaeotropical scolytine genus Hadrodemius Wood are reviewed. The following new synonymy is proposed: Hadrodemius comans (Sampson) (= Xyleborus amorphus Eggers syn.n., = Xyleborus metacomans Eggers syn.n.), Hadrodemius globus (Blandford) (= Xyleborus tomentosus Eggers syn.n.), Hadrodemius pseudocomans (Eggers) (= Xyleborus artecomans Schedl syn.n.). Hadrodemius (Xyleborus) pubifer (Schedl) is transferred to the genus Coptodryas Wood. Xyleborus melli Schedl is misplaced by Wood &Bright (1992) as a synonym of Hadrodemius amorphus and is here transferred to Xylosandrus Reitter. The following new synonymy is proposed: Xylosandrus amputatus (Blandford) (= Xyleborus melli Schedl syn.n.). A key to the females of the three species now included in the genus is provided. The taxonomy, distribution and biology of the species are briefly reviewed, and some new records included. Copyright © 2010 • Magnolia Press.
