Spermatozoa and phylogeny of Curculionoidea (Coleoptera)

In the examined families of Curculionoidea (Coleoptera), the sperm, although characteristic of typical pterygote insects, shows a few peculiarities that suggest Curculionoidea to be a homogeneous group. The curculionid sperm, in fact, always follows a similar structural design, without any variation. For example, it has 2 mitochondrial derivatives of different sizes, the larger of which is almost completely filled with a crystalline protein, the other being more moderately crystallized and almost completely occupied by cristae, and 2 accessory bodies of different sizes that are made up of a crystalline portion, crescent-shaped in section, and a “puff”-like expansion that is of different consistency, shape, and symmetry in various cases. The different extensions of the accessory bodies seem, therefore, to compensate for the high degree of asymmetry due to the largely different sizes of the 2 mitochondrial derivatives.The examined families and subfamilies can be arranged in 2 groups: Rhynchitidae appear drastically isolated, because they have a peculiar “9 + 9 + 0” axoneme, and show, moreover, a limited degree of asymmetry in the tail organelles. The remaining families and subfamilies are more closely related to one another by the presence of a “9 + 9 + 2” classical axoneme and by the same degree of asymmetry in the tail, typical of curculionid sperm. Among them, Apionidae are distinguished for the space containing the extraacrosomal layer, which may be hollow or absent, a twice-stepped nucleus-tail connection, and a thick glycocalyx at the end of the tail.The Curculionidae conserve primitive characters, such as the 3-layered acrosomal complex and “9 + 9 + 2” axoneme, but also present a high degree of differentiation in the shape of the asymmetrical tail organelles. There appear to be 3 clusters: the first cluster includes Brachyderinae, Leptopiinae, Gymnetrinae, Cryptorhynchinae, Rhynchophorinae. The second cluster includes Scolytidae, Cleoninae, Hylobiinae. The third cluster is more numerous and heterogeneous and shows 3 subgroups. The first of these includes only Otiorhynchinae. The sum of their characters shows that they have most of the common features of primitive curculionids; however the differences between a genus and another are so large that they could be assigned to different subfamilies. The second subgroup includes Hyperinae, Pissodinae, Magdalinae, Ceutorhynchinae and Cossoninae, and the third group includes Cioninae, Anthonominae, and Barimae.It is difficult to arrange these subfamilies (frequently recognizable for a different combination of the same recurrent characters) in a phylogenetic tree. However, we observed signs of primitiveness in Brachyderinae (small crescents) and their cluster; advanced ones in the third and fourth clusters all evolved with different patterns of the puff-like expansion of one of the accessory bodies, the latter being the most peculiar character of the superfamily. A tentative reconstruction is given.The functional significance of the variations seems to be that Rhynchitidae seem to be evolving towards immotility (their spermatozoon, in fact, is able to produce only a series of vibrations, not the progressive series of waves as in all other species studied), while all the other families and subfamilies show no signs of alterations in axonemal pattern and motility. The main evolutionary pathways observed in them are towards compensating for an exaggerated lengthening and a greater degree of asymmetry in the tail organelles: one of them, the major mitochondrial derivative, acts as a rigid axis, while the axoneme produces undulations in the opposite portion of the axonemal section.     

New curculionoid beetles (Coleoptera: Curculionoidea) from the Baltic amber

New genera and species of curculionid beetles from the Baltic amber, Pseudoglaesotropis martynovi gen. et sp. nov. (Anthribidae), Palaeometrioxena zherikhini gen. et sp. nov. (Belidae), Eocenorhynchites vossi gen. et sp. nov. (Rhynchitidae), and Archaeosciaphilus marshalli gen. et sp. nov. (Curculionidae), are described.     

A new genus of nemonychid weevil from Burmese amber (Coleoptera,Curculionoidea)

The first fossil nemonychid (Nemonychidae) in Burmese amber, belonging to the subfamily Rhinorhynchinae, is described and figured as Burmonyx zigrasi Davis & Engel, gen. n. and sp. n. While this specimen also comprises the first definitive record of the subfamily in the Asian continent, other compression fossils exist at least from the Yixian Formation of China and the Karatau site of Kazakhstan which may also deserve placement within this group. Although several important areas of the body are obscured by the shape and fragmented condition of the amber piece, a sufficient number of features are visible to consider adequate placement within Rhinorhynchinae, including the fairly strongly punctate elytral striae and appendiculate, nearly bifid pretarsal claws.

New and little known weevils (Coleoptera: Curculionoidea) from the Paleocene of Menat (France)

Two new genera Petropsis gen. n., and Menatorhis gen. n., and two species, Petropsis rostrata gen. et sp. n. (Ithyceridae) and Perapion menatensis sp. n. (Brentidae), are described from the Paleocene of Menat (France). Petropsis rostrata gen. et sp. n. is similar to Cretocar luzzii Gratshev et Zherikhin (2000) but differs from it in the comparatively short ventrites 1 and 2, almost straight and not dilated metatibiae, short precoxal portion of the prosternum, slightly convex elytra and antennae inserted more closely to the middle of the rostrum. Perapion menatensis sp. n. is similar to Perapion antiquum (Gyllenhal, 1833) but differs from it in the straight rostrum, sparser and finer punctures of the pronotum, and somewhat larger body. The families Ithyceridae and Brentidae are recorded for the first time in the Paleocene of Menat. The systematic positions of Balaninus elegans Piton (1940) (type species of Menatorhis gen. n.) and Hipporhinus ventricosus Piton (1940) are discussed.     

Notes on chromosome numbers and C-banding patterns in karyotypes of some weevils from central Europe (Coleoptera, Curculionoidea: Apionidae, Nanophyidae, Curculionidae)

Chromosome numbers and C-banding patterns of sixteen weevil species are presented. The obtained results confirm the existence of two groups of species with either a small or large amount of heterochromatin in the karyotype. The first group comprises twelve species (Apionidae: Oxystoma cerdo, Eutrichapion melancholicum, Ceratapion penetrans, Ceratapion austriacum, Squamapion flavimanum, Rhopalapion longirostre; Nanophyidae: Nanophyes marmoratus; Curculionidae: Centricnemus (=Peritelus) leucogrammus, Sitona humeralis, Sitona lineatus, Sitona macularis, Sitona suturalis). In weevils with a small amount of heterochromatin, tiny grains on the nucleus during interphase are visible, afterwards appearing as dark dots during mitotic and meiotic prophase. The second group comprises four species from the curculionid subfamily Cryptorhynchinae (Acalles camelus, Acalles commutatus, Acalles echinatus, Ruteria hypocrita) which possess much larger heteropycnotic chromosome parts visible during all nuclear divisions. The species examined have pericentromeric C-bands on autosomes and on the X chromosome.     

Fossil history of Mesozoic weevils (Coleoptera: Curculionoidea)

Abstract The first synopsis of Mesozoic weevils (Curculionoidea: Coleoptera) is presented. Changes of family, genera and species abundance during the Mesozoic revealed three distributional patterns. The Jurassic (Karatau) fauna was dominated by the Nemonychidae. During the Early Cretaceous (beginning at the Jurassic/Cretaceous border), the Ithyceridae was the prevalent group with a significant role played by the Nemonychidae. In the Late Cretaceous (Cenomanian and Turonian), the major groups were the Curculionidae and Brentidae. Obviously, the change of weevil fauna during this period was due to the expansion of the angiosperms, which provided multiple niches in their vegetative and reproductive organs for weevil development.     

New data on the distribution and host plants of weevils (Coleoptera,Curculionoidea: Apionidae,Curculionidae) in the south of Baikal Siberia and in Mongolia

Two weevil species, Rhinoncus autumnalis Korotyaev, 1980 and Orchestes medvedevi (Korotyaev, 1995), comb. n. (from Rhynchaenus), both described from Mongolia, are recorded from Russia (Buryatia) for the first time. A key to five Orchestes species associated with elms in Eastern Siberia, the Russian Far East, and Mongolia is provided. Aizobius sedi (Germar, 1818) is recorded for the first time from Eastern Siberia based on the recent findings in Buryatia and on older collections from Tuva where it is associated with Orostachys spinosa (L.) C.A. Mey. (Crassulaceae); it is also recorded for the first time from Kyrgyzstan and Mongolia. Magdalis (Aika) margaritae Barrios, 1984, native of Mongolia, Northern China and the south of the Russian Far East, is recorded from Buryatia. Lixus (Broconius) korotyaevi Ter-Minassian, 1989, formerly known in Russia only from southern Tuva, is recorded from Buryatia where it was collected on Suaeda ?prostrata Pallas, which is the first known host of this species. Rhamphus ?oxyacanthae (Marsham, 1802) is reported from Buryatia where it was collected from Cotoneaster melanocarpa, and from Mongolia.

Two new genera of Nanophyidae with six desmomeres (Coleoptera, Curculionoidea)

A new genus Lyalia is described in Nanophyidae and three species are included in it: Lyalia curvatasp. n. (Vietnam), Lyalia robusta (Pic, 1921), comb. n. (from Nanophyes) (Java, Bali, Laos) and Lyalia albolineata (Pajni & Bhateja, 1982), comb. n. (from Ctenomerus) (India: Assam). Ctenomerus lagerstroemiae G. A. K. Marshall, 1923 is a syn. n. of Lyalia robusta. Thus, the genus Ctenomerus Schoenherr, 1843 is restricted to the Afrotropical Realm. Kantohiagen. n. is erected for Kantohia taiwana (Kantoh & Kojima, 2009) (from Shiva) (Taiwan). A key to the Nanophyinae genera with six desmomeres is presented.     

New tribes of the superfamily Curculionoidea (Coleoptera) in Burmese amber

Two new tribes in the Curculionoidea are described as the Anchineini Poinar and Legalov, n. trib. (Ithyceridae: Carinae) and Paleocryptorhynchini Poinar and Legalov, n. trib. (Curculionidae: Erirhininae). The genus Anchineus Poinar and Brown, 2009, n. placem. is transferred from the subfamily Curculioninae of the family Curculionidae to the subfamily Carinae of the family Ithyceridae. The genus Paleocryptorhynchus Poinar, 2009, n. placem. is transferred from the subfamily Cryptorhynchinae to the subfamily Erirhininae. The placement of the genus Mesophyletis Poinar, 2006 in the family Ithyceridae was confirmed. http://www.zoobank.org/urn:lsid:zoobank.org:pub:0C0039DD-7BC6-4A54-9282-F43C5606D68B     

Revision of the subgenus Neosynaptops Voss of Euops Schoenherr (Coleoptera, Curculionoidea, Attelabidae) from the Papuan region

The subgenus Neosynaptops Voss of Euops Schoenherr is revised. It contains two previously described species, E. cupreosplendens Macleay and E. viridiceps Voss, plus seven new ones: E. doertheae sp. n., E. gladiator sp. n., E. paraviridiceps sp. n., E. punctaticeps sp. n., E. similis sp. n., E. waigeoensis sp. n. and E. wapogae sp. n. A lectotype is designated for E. viridiceps Voss. The species are described and the characters relevant for their identification, especially the male genitalia, are illustrated. A key to the species is provided. Three distinct types of proventriculi found in species of Neosynaptops are illustrated. A cladistic analysis is performed which confirms the monophyly of Neosynaptops . The most important apomorphies are the punctate-rugose sculpture of the gena and the longitudinal costae on the ventral surface of the rostral base. The group is restricted to New Guinea and some small neighbouring islands.     

A new genus of the tribe Acratini from the continental Neotropical region (Coleoptera: Curculionoidea,Brentidae)

A group of 10 species belonging to the Neotropical tribe Acratini Alonso-Zarazaga, Lyal, Bartolozzi & Sforzi 1999, is shown to be monophyletic by a phylogenetic analysis based on 48 morphological characters. A new genus, Pertusius n. gen., is described, based on three derived characters of external and genital morphology: venter of prorostrum of males with fine median longitudinal carina, base of elytra with deep pit at the place of insertion on mesonotum, and proximal sclerite of endophallus more or less horseshoe-shaped. Eight species were previously known and, according to former authors, belonged to the genera Acratus Lacordaire 1865 [Pertusius apicalis (Sharp 1895), n. comb., P. errabundus (Kleine 1927), n. comb., P. extrarius (Kleine 1927), n. comb., P. fidus (Kleine 1927), n. comb. and P. telesi (Soares & Meyer 1959), n. comb.] and Proteramocerus Kleine 1921 [Pertusius chalcites (Perty 1832), n. comb., P. filum (Sharp 1895), n. comb., and P. laevis (Germar 1824), n. comb.].
