First report of Austroporus doctus (Blackburn) from New Zealand and description of its larva (Coleoptera: Phalacridae)

The Australian species Austroporus doctus (Blackburn) is reported from New Zealand for the first time. Adults are illustrated and diagnosed, and late-instar larvae are fully described and illustrated. In addition, a summary of prior larval descriptions of Phalacridae is provided. This represents the first description of the morphology and habitat of the larvae within the genus Austroporus Gimmel and the Olibroporus-group of genera. Austroporus doctus is native to eastern Australia, where adults are distinguished from similar species by characters of the male genitalia and by a suite of external morphological features. There are no native members of Phalacridae known from New Zealand, but A. doctus represents the second introduced and established species there. A key is given to differentiate adult and larval A. doctus from the other introduced New Zealand species, Phalacrus uniformis (Blackburn)

Epuraea imperialis (Reitter, 1877). New invasive species of Nitidulidae (Coleoptera) in Europe, with a checklist of sap beetles introduced to Europe and Mediterranean areas

Australian species Epuraea imperialis (Reitter, 1877), previously introduced to New Zealand, is recorded as a new invasive species from the Canary Islands, Continental Spain, Portugal, France, Belgium, and Italy. It is redescribed and figured, and its taxonomic position in the genus Epuraea Erichson, 1843 is discussed. A tentative checklist of sap beetles introduced to Europe and the Mediterranean areas is finally included

Integrated phylogenomics and fossil data illuminate the evolution of beetles

Beetles constitute the most biodiverse animal order with over 380,000 described species and possibly several million more yet unnamed. Recent phylogenomic studies have arrived at considerably incongruent topologies and widely varying estimates of divergence dates for major beetle clades. Here we use a dataset of 68 single-copy nuclear protein coding genes sampling 129 out of the 193 recognized extant families as well as the first comprehensive set of fully-justified fossil calibrations to recover a refined timescale of beetle evolution. Using phylogenetic methods that counter the effects of compositional and rate heterogeneity we recover a topology congruent with morphological studies, which we use, combined with other recent phylogenomic studies, to propose several formal changes in the classification of Coleoptera: Scirtiformia and Scirtoidea sensu nov., Clambiformia ser. nov. and Clamboidea sensu nov., Rhinorhipiformia ser. nov., Byrrhoidea sensu nov., Dryopoidea stat. res., Nosodendriformia ser. nov., and Staphyliniformia sensu nov., Erotyloidea stat. nov., Nitiduloidea stat. nov., and Cucujoidea sensu nov., alongside changes below the superfamily level. Our divergence time analyses recovered a late Carboniferous origin of Coleoptera, a late Paleozoic origin of all modern beetle suborders, and a Triassic–Jurassic origin of most extant families, while fundamental divergences within beetle phylogeny did not coincide with the hypothesis of a Cretaceous Terrestrial Revolution

The beetle tree of life reveals that Coleoptera survived end-Permian mass extinction to diversify during the Cretaceous terrestrial revolution

Here we present a phylogeny of beetles (Insecta: Coleoptera) based on DNA sequence data from eight nuclear genes, including six single-copy nuclear protein-coding genes, for 367 species representing 172 of 183 extant families. Our results refine existing knowledge of relationships among major groups of beetles. Strepsiptera was confirmed as sister to Coleoptera and each of the suborders of Coleoptera was recovered as monophyletic. Interrelationships among the suborders, namely Polyphaga (Adephaga (Archostemata, Myxophaga)), in our study differ from previous studies. Adephaga comprised two clades corresponding to Hydradephaga and Geadephaga. The series and superfamilies of Polyphaga were mostly monophyletic. The traditional Cucujoidea were recovered in three distantly related clades. Lymexyloidea was recovered within Tenebrionoidea. Several of the series and superfamilies of Polyphaga received moderate to maximal clade support in most analyses, for example Buprestoidea, Chrysomeloidea, Coccinelloidea, Cucujiformia, Curculionoidea, Dascilloidea, Elateroidea, Histeroidea and Hydrophiloidea. However, many of the relationships within Polyphaga lacked compatible resolution under maximum-likelihood and Bayesian inference, and/or lacked consistently strong nodal support. Overall, we recovered slightly younger estimated divergence times than previous studies for most groups of beetles. The ordinal split between Coleoptera and Strepsiptera was estimated to have occurred in the Early Permian. Crown Coleoptera appeared in the Late Permian, and only one or two lineages survived the end-Permian mass extinction, with stem group representatives of all four suborders appearing by the end of the Triassic. The basal split in Polyphaga was estimated to have occurred in the Triassic, with the stem groups of most series and superfamilies originating during the Triassic or Jurassic. Most extant families of beetles were estimated to have Cretaceous origins. Overall, Coleoptera experienced an increase in diversification rate compared to the rest of Neuropteroidea. Furthermore, 10 family-level clades, all in suborder Polyphaga, were identified as having experienced significant increases in diversification rate. These include most beetle species with phytophagous habits, but also several groups not typically or primarily associated with plants. Most of these groups originated in the Cretaceous, which is also when a majority of the most species-rich beetle families first appeared. An additional 12 clades showed evidence for significant decreases in diversification rate. These clades are species-poor in the Modern fauna, but collectively exhibit diverse trophic habits. The apparent success of beetles, as measured by species numbers, may result from their associations with widespread and diverse substrates – especially plants, but also including fungi, wood and leaf litter – but what facilitated these associations in the first place or has allowed these associations to flourish likely varies within and between lineages. Our results provide a uniquely well-resolved temporal and phylogenetic framework for studying patterns of innovation and diversification in Coleoptera, and a foundation for further sampling and resolution of the beetle tree of life.This is the publisher’s final pdf.

Laricobius caucasicus Rost 1893

3. Laricobius caucasicus Rost, 1893 (figs 3) Diagnosis. Body bicolored. Head dark; ocelli present. Prothorax transverse with well developed lateral carina and sides explanate. Pronotum light; posterior tooth absent. Scutellum dark. Surface of elytra not incurvate; elytral punctures not confluent. Epipleura light. Ventrites dark. Femora light. Tibiae light. Description. Length 2.56 mm. Body bicolored, mostly dark tan above, head, scutellum, and ventrites black, hypomeron and epipleuron tan; antenna and legs tan with AI darker. Dorsal surfaces subglabrous. Head with ocelli; u-shaped furrow present; interocular distance about 4 x the width of the eye; macropunctures ovate or fused, small to lineate and shallowly impressed, absent from central area of frons; micropunctures coarse; setation short, erect to suberect, length about half the width of the eye. Antenna with length of A 3 about equal to A 4, ratios 2.1: 2.1: 1.4: 1.4: 1.4: 1.3: 1.2:1.0: 1.5: 1.6: 2.3; A 11 not strongly asymmetrical. Prothorax transverse and dorsoventrally flattened, widest at middle, sides gradually narrowing anteriorly and more steeply convergent posteriorly; about 0.72 x as long as wide (pronotal length/greatest pronotal width = 0.72); depth = 0.24 mm; pronotum laterally broadly explanate with well developed lateral carina with a distinct sharp edge; anterior angle about 65 ° and not forming a tooth (may be obscured by setae); posterior angle indistinct and broadly rounded and without a short tooth; foveae visible in dorsal view; macropunctures ovate, deep, and well-separated; micropunctures coarse; setae erect and elongate, longer than half the width of eye. Elytra about 3.30 x as long as wide (elytral length/greatest elytral width = 3.30) and 3.41 x as long as pronotum (elytral length/pronotal length = 3.41); surface not incurvate at basal third; macropunctures not coalescing posteriorly to form grooves, separated by an average of 1 puncture diameter; micropunctures fine; microsculpture not visible; vestiture biseriate, mostly consisting of suberect setae, with scattered erect setae, elongate and about 2 / 3 the length of the eye. Comments. Among the species that have an explanate pronotal margin, L. caucasicus is one of three species that has the head darker than the pronotum. It can be distinguished from L. laticollis and L. baoxingensis by the shape of the pronotum. Rost (1893) mentions in the description that L. caucasicus that there is a shallow impression before the middle of the elytra; this feature is lacking in the specimen here examined. Háva (2006) listed the type deposition of Rost’s specimen(s) of L. caucasicus as questionably in the MFNB, and queries for types to Berlin and Dresden where some of the Rost material was eventually deposited, either by direct deposition or by exchange (Horn et al. 1990), did not yield specimens. A single specimen that is provisionally identified as L. caucasicus based on the original description and matching the distribution recorded in Rost (1893) is described here. I decided not to name this specimen as a neotype because the abdomen and hind legs of the female specimen (N. Havill, pers. com.) were removed for DNA work prior to this study. Hosts.

Head with ocelli; u-shaped furrow present but weakly impressed; interocular distance about 4 x the width of the eye; macropunctures weakly to strongly impressed, ovate; micropunctures coarse; setation elongate, erect, average length about 2 / 3 to full width of the eye. Antenna with length of A 3 about equal to A 4, ratios 1.9: 1.7: 1.4: 1.3: 1.4: 1.2: 1.2:1.0: 1.3: 1.4: 1.8; A 11 not strongly asymmetrical. Prothorax transverse and dorsoventrally flattened, widest at middle, sides weakly sinuate or unevenly convex, with margin converging more sharply posteriorly than anteriorly; about 0.75 x as long as wide (pronotal length/greatest pronotal width = 0.67–0.81, x = 0.75); depth = 0.25–0.39 mm (x = 0.30); pronotum laterally broadly explanate, lateral carina with a distinct sharp edge; anterior angle variable from 90 º to about 65 °, acute but not forming a tooth; posterior angle distinct and marked by a short tooth that may be weakly formed; foveae visible in dorsal view; macropunctures ovate, deep, usually wellseparated but sometimes contiguous; micropunctures coarse; setae erect and elongate, length about 2 / 3 to full width of eye. Elytra about 3.22 x as long as wide (elytral length/greatest elytral width = 2.75–3.65, x = 3.22) and 3.25 x as long as pronotum (elytral length/pronotal length = 3.00– 3.67, x = 3.25); surface strongly to weakly incurvate at basal third; macropunctures not coalescing posteriorly to form grooves (apart from those of striae 1 along the suture at the apical 1 / 3 in some specimens), separated by an average of 1 / 2 puncture diameter; micropunctures fine; microsculpture visible or not; vestiture mostly consisting of suberect setae with scattered erect setae, elongate and average length about 2 / 3 to full width of eye. Aedeagus with phallobase transverse (wider than long), about 2 / 3 the length of the median lobe, median carina absent; median lobe projecting beyond apices of parameres, relatively broad with its greatest width larger than the width of the parameres, gradually tapering apically with apex subacute, median carina or groove absent, ostium subapical; parameres moderately broad, apex angulate, short setae present on apices and absent along inner margin, internal subapical ridge present. Spiculum gastrale apically acute. Comments. Laricobius rubidus can be distinguished from other bicolored species with ocelli and explanate pronotal margins (especially the similar looking L. erichsonii) by the dark-colored tibiae which is the same color as the femora, by the punctures on the head shallowly impressed, the anterior angle not forming a tooth, and most easily by the aedeagal characters. The internal subapical ridge on the parameres is shared only with the species L. nigrinus. Preliminary genetic data suggest that L. nigrinus and L. rubidus can successfully reproduce in the field (Havill et al. in press).

Comments. Laricobius baoxingensis is the only species of the genus with a subparallel-sided explanate margin (fig 1). The pronotal shape is somewhat similar to L. taiwanensis, but can easily be distinguished from it by the coloration of the head and elytra and presence of ocelli. The holotype in IZAS was not examined. The dissected male for this study was not part of the type series and the illustrations published in Háva (2009 a, Fig. 3; 2009 c, Fig. 4) of the genitalia do not match the specimens here. The pinned specimens of the type series were covered with a residue making some of the cuticular and setal characters difficult to observe. The spiculum gastrale was not observed. Hosts.
