Hylesininae

Belongs within: Curculionidae.Contains: Hylesinini, Hylurgini, Hylurgops, Polygraphini, Crypturgini, Hypoborini, Dryocoetini, Xyleborini, Ipini, Corthylini, Xyloctonini, Cryphalus. The name Hylesininae is available for a clade of bark beetles usually classified in recent years within the subfamily Scolytinae but suggested to be distinct by recent molecular phylogenies (e.g. Mugu et al. 2018). Subgroups include the Cryphalina, characterised by… Continue reading Hylesininae

Cryphalus

Belongs within: Hylesininae. Cryphalus is a genus of monogamous, phloeophagous bark beetles found in the Old World and North America (Wood 1986). Characters (from Wood 1986): Antennal funicle four-segmented, antennal club strongly flattened with aseptate, recurved (occasionally weakly procurved) sutures clearly marked by grooves and setae; eye emarginate; both basal and basal third of lateral… Continue reading Cryphalus

Ipini

Belongs within: Hylesininae. The Ipini are a cosmopolitan genus of bark beetles with the rear face of the elytra more or less excavated, with the lateral margin typically armed by tubercles or spines. All are phloeophagous and the majority are heterosanguineously polygynous. The African genus Dendrochilus is distinguished having the eyes short, oval and entire… Continue reading Ipini

Corthylini

Belongs within: Hylesininae.Contains: Araptus, Conophthorus, Pityophthorus, Corthylus. The Corthylini are a cosmopolitan group of bark beetles (not found in Australia) characterised by emarginate eyes, a strongly flattened antennal club, and relatively slender tibiae. A small transverse groove on the rear of the metepisternum allows the elytra to be locked into place when closed. Corthylins may… Continue reading Corthylini

Dryocoetini

Belongs within: Hylesininae. Cyrtogenius is a genus of bark beetles found from Africa to Micronesia; members of this genus are phloeophagous and heterosanguineously polygynous (Wood 1986). <==Dryocoetini [Dryocoetina, Dryocoetoideae, Taphrorychini, Thamnurginae] |–Toxophthorus Wood 1986 [=Toxophorus Eggers 1920 (preoc.)]W86 | `–*T. africanus (Eggers 1920) [=*Toxophorus africanus]W86 |–Taphramites Schedl 1947W86 | `–*T. gnathotrichus Schedl 1947W86 |–Thamnurgus Eichhoff… Continue reading Dryocoetini

Xyleborini

Belongs within: Hylesininae. Xyleborus is a cosmopolitan genus of xylomycetophagous (i.e. feeding on fungi growing on wood) bark beetles. Members of this genus are consanguineously polygynous, with haploid flightless males (Wood 1986). <==Xyleborini [Webbinae, Xylebori, Xyleborina] |–Xyleborites Wickham 1913W86 | `–*X. longipennis Wickham 1913W86 |–Sampsonius Eggers 1935W86 | `–*S. sexdentatusW86 |–Schedlia Browne 1950W86 | `–*S.… Continue reading Xyleborini

Conophthorus

Belongs within: Corthylini. Conophthorus is a North American genus of bark beetles feeding on seeds in cones of Pinus species (Wood 1986). Characters (from Wood 1986): Body length 2.2–4.1 mm. Sutures 1 and 2 of antennal club aseptate and clearly marked by grooves and rows of setae; basal margins of pronotum marked by a finely… Continue reading Conophthorus

Hylurgops

Belongs within: Hylesininae. Hylurgops is a Holarctic genus of monogamous bark beetles breeding in phloem tissues of Pinaceae (Wood 1986). Characters (from Wood 1986): Pronotum usually constricted anteriorly, usually about equal numbers of small and large punctures intermixed on disc; striae 10 obsolete behind level of posterior coxae, only striae 9 continuing caudad; third tarsal… Continue reading Hylurgops
