... NEW GENUS OF SPIDER BEETLE Etymology. The specific epithet honors the parents of the first author, whose efforts and motivation helped to make his studies at Western Kentucky University and elsewhere possible. Diagnosis. This species can be characterized by: a moderately V-shaped visible cuticle on the pronotum anteriorly between the setal tufts (Fig. 28); abrupt upward curvature of the visible cuticle to the base of the pronotal tufts (P. harrisoni curves up more gradually); apex of parameres distinctly expanded (Fig. 36) (P. harrisoni has the apex more parallel ...

... patches of recumbent white setae located anteriorly within puncture rows 6-8 and posteriorly within rows 3-4 and 7-8. Male genitalia with parameres thinnest near apical 1/3, strongly curved inwards near apex, apices distinctly expanded; median lobe with sides parallel sided except near apex total length 83% of that of parameres measured from base (Fig. ...

Cryptopeniculus nigrosetus, a new genus and species of spider beetle from Namaqualand, western South Africa, is described. It is characterized by a unique pronotal vestiture composed of a "V" shaped flocculant pale brown setal tuft covering most of the dorsal surface that is partially obscured by an outer layer of thick darker colored setae forming...

... La condición no voladora no es recurrente dentro de Ptinidae, aunque está registrado apterismo y braquipterismo en la familia, especialmente en hembras (Philips y Bell 2010). En ambientes xéricos, la subfamilia Ptininae es particularmente diversa en especies no voladoras (Akotsen-Mensah y Philips 2009;Philips et al. 2020). ...
Se describe la hembra de Desertinastes rotundus Honour (Coleoptera: Ptinidae), se señalan las diferencias con respecto al macho, entre otros caracteres por su condición braquíptera, y se entregan los primeros registros de plantas hospedantes para la especie.
... As of today, there are 14 endemic genera, four widespread genera, and 48 species of South African spider beetles described (for the most recent works, see Irish, 1996a,b;Philips and Foster, 2004;Borowski, 2006aBorowski, ,b, 2009Bell and Philips, 2008;Akotsen-Mensah and Philips, 2009;Smiley and Philips, 2011;Trimboli and Philips, 2011;Wood and Philips, 2013), making South Africa home to some of the highest spider beetle diversity currently known in the world. Undoubtedly many species still remain undocumented due to their small size, perhaps small populations, and certainly for some, limited distributions. ...
Six new species of spider beetle are described from southwestern Peru: Cordielytrum silvae, sp. n., C. inca, sp. n., C. fimbriatum, sp. n., C. obscurum, sp. n., C. adustum, sp. n., and C. globuloides, sp. n. The potential for undescribed diversity in this genus is discussed, as well as the geographic distribution and biology of species.
... About 25 percent of the described genera of the family Ptinidae, sensu stricto (i.e., including only the spider beetles and not the anobiids) are found in South Africa. This currently includes 13 endemic genera, four additional widespread genera, and 47 documented species (see Irish 1996aIrish , 1996bPhilips & Foster 2004;Borowski 2006aBorowski , 2006bBorowski , 2009Bell & Philips 2008;Akotsen-Mensah & Philips 2009;Smiley & Philips 2011;Trimboli & Philips 2011). ...
A unique new genus and species of spider beetle from Namaqualand from the Succulent Karoo Biodiversity Hotspot in South Africa is described. The genus Carinomezium gen. n. is characterized by pronounced longitudinal carinae on the elytra, four large rounded setal tufts that cover the pronotum, and the very small body size. The single representative species, Carinomezium namaquaensis sp. n. is diagnosed, described, and illustrated. The phylogenetic placement of this taxon is also discussed.
A catalogue of all the known genera and subgenera of the Coleoptera series Derodontiformia and Bostrichiformia, each with a single superfamily (Derodontoidea and Bostrichoidea, respectively), is provided. The following new tribes are established and type genera are designated: Apphianini Háva trib. nov., Ranolini Háva trib. nov. (all Dermestidae); Ochinini Zahradník trib. nov., Phanerochilini Zahradník trib. nov. (all Ptinidae). The subgenus Paranovelsis has been
removed as a synonym and has been reelevated to generic rank. The following new synonymies are proposed: Megatoma Herbst, 1791 (= Perimegatoma Horn, 1875 syn. nov., Caucasotoma Mroczkowski, 1967 syn. nov.); Trinodes Dejean, 1821 (= Trinodus Gistl, 1856 syn. nov.); Nosodendron Latreille, 1804 (= Nosodendrium Gistl, 1856 syn. nov.); Casapus Wollaston, 1862 (= Pithodes Wollaston, 1862 syn. nov.).
Nine new species of Pseudomezium are described, and the two previously documented species are included. The unique morphological characteristics of each species, including genitalia, are illustrated. The morphological characteristics of the genus, including mouthparts and ventral structures are also illustrated. Lastly, a discussion of the potential of spider beetles for conservation efforts in South Africa is presented.

Meziomorphum montagu Trimboli and Philips, new species, from Montagu Cave near the town of the same name in South Africa is described. This species, like all others within the genus, is characterized by an unusual pronotal setal structure composed of a thin inflated shell covering the surface to various degrees, as well as stout, erect leg and elytral spines. It is suspected to be a cave endemic, the only species in this genus with this characteristic currently known.
Nine new species of Pseudomezium are described, and two previously described species are also considered. The unique morphological characteristics, including genitalia, of each species are illustrated and a key is given for all taxa. The morphological characteristics of the genus, including mouthparts and ventral structures are also illustrated. A brief discussion of the spider beetle diversity of South Africa and the potential of spider beetles for conservation efforts is also presented.
