We have tried to assess the morphological changes in insects under conditions of global warming using the example of three mass species. We analyzed collection funds for 140 years from the same territory in Western Siberia. We found out that the climate of Siberia is systematically drying up and the average temperatures are increasing, and as a result, the species composition of the fauna of Western Siberia changes, as well as the morphology of some insect species.

Genus ChalybionDahlbom, 1843 Chalybion has the most complex and differentiated cocoon among genera of Sceliphrinae, apparently due to the retention of ancestral traits, as discussed below. Rau (1915) commented that cocoons of C. californicum are similar to those of Sceliphorn, but have an additional external silken wall, which is a feature not observed in other Sceliphrinae. Pham (2017, fig. 1d) illustrated a cocoon of Chalybion malignum (Kohl, 1906) in which the external layer of silk is denser than observed in species of Sceliphron.

In this study, forewing teratology in 42 species of solitary wasps belonging to the family Sphecidae (Hymenoptera) collected from various provinces of Turkey were investigated for the first time. In total, 20 cases of wing venation anomalies, classified as: a) irregular vein course, b) supernumerary veins, c) defective veins and d) supernumerary cells, were observed in 112 of 1682 specimens. The most encountered wing venation anomalies were: a spur protruding from 1 m-cu to 1st discoidal cell (n = 42, 37.50%), an incomplete 1r-m cross-vein (n = 21, 18.75%), and completely reduced 1r-m cross-vein (n = 10, 8.92%). The anomalies were rather common in the species Podalonia fera (n = 19, 36.53%), P. luffi (n = 11, 33.33%), P. hirsuta (n = 18, 33.33%) and Chalybion walteri (n = 1, 33.33%). In general, anomalies were more frequently observed in male wasps (n = 65, 58.03%). Teratology could be caused by genetic, environmental or pathogenic factors.

The nesting biology ofChalybion turanicum(Gussakovskij, 1935) has been studied, with a total of 31 nests being examined. All studied nests were located inside the old nest cells ofSceliphron destillatorium(Illiger, 1807). Each nest ofCh. turanicumconsisted of a single cell. Females hunted for spiders, with 18 species in five families being identified among their prey. Two most abundant victim groups were Theridiidae (eight species, 54% of specimens) and Araneidae (seven species, 33% of specimens) spiders. A spider number stored in a cell varied from five to 31 (mean = 17.6 ± 5.4). In the Crimea,Ch. turanicumhas one generation per year with reproductive success of 67%. Two species of the nest parasites were reared from cells ofCh. turanicum:Chrysis taczanovskiiRadoszkowski, 1876 andAcroricnus seductor(Scopoli, 1786).Chalybion turanicumis the seventh invasive species of Sphecidae naturalized in Europe.

The genus Chalybion Dahlbom, 1843 from northwest Vietnam is studied. Six species of the genus are recorded for the area. Of these, C. dolichothorax (Kohl, 1918) and C. gracile Hensen, 1988 are new records, whereas C. tanvinhensis sp. nov. is described as a new species. Notes on the nest of the new species and keys to both sexes of the six species reported from northwest Vietnam are provided.

Chalybion tanvinhensis Pham & Ohl, sp. nov. (Figs. 1‒10) Material examined: Holotype, ♀, pinned (deposited in IEBR, VAST), VIETNAM: Hoa Binh, Tan Vinh, Luong Son, 2.v.2017, Phong Huy Pham [IEBR]. Paratypes (IEBR, VAST): VIETNAM: Son La: 2 ♂♂, Chieu Village, Muong Thai, Ham Yen, 11.viii.2017, Phong Huy Pham [IEBR]. Diagnosis: Chalybion tanvinhensis is a member of the C. fabricator species-group because of the following combination of characters: Anterior margin of clypeus with five distinct teeth (median three close together, lateral teeth sharp and rather distant from others), integument dark blue, tarsi without plantulae, lower metapleuron area without angular carina, a rim at propodeal base only behind metanotum, metapleuron distinctly depressed below level of mesopleuron and side of propodeum, sixth metasomal sternum of female flat and apically broadly truncate. This species can be easily distinguished from the other seven species of the C. fabricator species-group known so far by the following combination of characters: forewing homogenously, light brownish; fourth metasomal sternum of female without micropubescence; median and submedian teeth of clypeus well separate; vertex finely, sparsely punctate; mesoscutum weakly transversely strigose, interspaces shallowly punctate; petiole markedly curved, much shorter than the hindbasitarsus; antenna black; mesopleuron coarsely, densely punctate; metasoma with violaceous reflections. Because males of the fabricator species-group are known only for C. hainanense, C. malignum and C. sulawesii, the male of this new species can easily be separated from them by having the clypeus without teeth and no placoids on seventh to ninth flagellomeres. This new species is similar to C. lividum and C. sulawesii, but it can be distinguished from the first by having black antenna, the median tooth of the clypeus much narrower than submedian teeth, the metasoma with violaceous reflections; from the latter by having lateral teeth of the clypeus in the female rather sharp; the forewing slightly, rather unevenly brownish; the medial and submedial cells most uniformly hyaline; petiole markedly curved, much shorter than the hindbasitarsus. The male of C. tanvinhensis is unique in Chalybion in having the following characters: clypeus without lateral tooth, median and submedian tooth fused into single protruding lobe, placoids on seventh to ninth flagellomere (similar to C. japonicum (Gribodo, 1882), C. ohli Dollfuss, 2016 and C. zimmermanni Dahlbom, 1843).

Chalybion tanvinhensis Pham & Ohl, sp. nov. (Figs. 1���10) Material examined: Holotype, ♀, pinned (deposited in IEBR, VAST), VIETNAM: Hoa Binh, Tan Vinh, Luong Son, 2.v.2017, Phong Huy Pham [IEBR]. Paratypes (IEBR, VAST): VIETNAM: Son La: 2 ♂♂, Chieu Village, Muong Thai, Ham Yen, 11.viii.2017, Phong Huy Pham [IEBR]. Diagnosis: Chalybion tanvinhensis is a member of the C. fabricator species-group because of the following combination of characters: Anterior margin of clypeus with five distinct teeth (median three close together, lateral teeth sharp and rather distant from others), integument dark blue, tarsi without plantulae, lower metapleuron area without angular carina, a rim at propodeal base only behind metanotum, metapleuron distinctly depressed below level of mesopleuron and side of propodeum, sixth metasomal sternum of female flat and apically broadly truncate. This species can be easily distinguished from the other seven species of the C. fabricator species-group known so far by the following combination of characters: forewing homogenously, light brownish; fourth metasomal sternum of female without micropubescence; median and submedian teeth of clypeus well separate; vertex finely, sparsely punctate; mesoscutum weakly transversely strigose, interspaces shallowly punctate; petiole markedly curved, much shorter than the hindbasitarsus; antenna black; mesopleuron coarsely, densely punctate; metasoma with violaceous reflections. Because males of the fabricator species-group are known only for C. hainanense, C. malignum and C. sulawesii, the male of this new species can easily be separated from them by having the clypeus without teeth and no placoids on seventh to ninth flagellomeres. This new species is similar to C. lividum and C. sulawesii, but it can be distinguished from the first by having black antenna, the median tooth of the clypeus much narrower than submedian teeth, the metasoma with violaceous reflections; from the latter by having lateral teeth of the clypeus in the female rather sharp; the forewing slightly, rather unevenly brownish; the medial and submedial cells most uniformly hyaline; petiole markedly curved, much shorter than the hindbasitarsus. The male of C. tanvinhensis is unique in Chalybion in having the following characters: clypeus without lateral tooth, median and submedian tooth fused into single protruding lobe, placoids on seventh to ninth flagellomere (similar to C. japonicum (Gribodo, 1882), C. ohli Dollfuss, 2016 and C. zimmermanni Dahlbom, 1843)., Published as part of Pham, Phong Huy, Ohl, Michael & Truong, Lam Xuan, 2019, The genus Chalybion Dahlbom, 1843 (Hymenoptera: Sphecidae) from Northwest Vietnam, with description of a new species, pp. 202-210 in Zootaxa 4712 (2) on page 205, DOI: 10.11646/zootaxa.4712.2.2, http://zenodo.org/record/3587019, {"references":["Gribodo, G.

S t a t u s: This is the type species of the genus Chalybion. It is the second species of the genus to have been studied minutely in Vietnam (see PHAM and DANG 2017), in fact, the first wasp to have been studied in north Vietnam. Specimens collected in my study course were found to note with C. japonicum (GRIBODO, 1882) and Sceliphron madraspatanum (FABRICIUS, 1781) in aspects of distribution. O c c u r r e n c e: C. bengalense is a common domestic species in India (JAYAKAR & SPURWAY 1964). This species was firstly described by FABRICIUS in 1775 but there was a clear mislocality. DAHLBOM (1845) redescribed the insect and showed its exact locality. To before 2001, although several field trips in north Vietnam had been produced by numerous oversea legmans such as A. WEISS in 1901 at Tuyen Quang and R. VIRALIS de SALVAZA in 1924 (see HENSEN 1988), JENDEK in 1995 at Tam Dao, Vinh Phuc, PACHOL��TKO & DEMBICK�� in 1996 at Tam Dao, Vinh Phuc and SOLD��N in 1984 at Hanoi (see DOLLFUSS 2016), no records of the species were documented. This leads me to suggest that whether or not C. bengalense is an exotic species, but the occurrence time and the manner of immigration of the species are not determined. And it is not impossible to mention the present large distribution of the wasp and miscollections of legmans. That HENSEN (1988) took field trips in north Vietnam, Hanoi and Ha Giang, for examble, and collected only specimens of C. japonicum but not those of C. bengalense showed that at that time C. japonicum is a common and abundant species in north Vietnam. My data collected for a long duration from 2001 to 2017 show that although the number of specimens of the species collected is limited because of no quantification, C. bengalense is a common and abundant species in north Vietnam. Most of the areas of study that I took, only either the presence of C. bengalense or that of C. japonicum. It means that both species are not active at the same site. To my knowledge, in two recent decades, abundance of C. bengalense has limited the number of C. janponicum as clearly evidenced in Hanoi area, and between these two species may be to contain interactional relationships that it is really different to explain in the present study. The occurrence of C. bengalense is very closely related to that of S. madraspatanum, a common and largely distributed mud dauber wasp of the genus Sceliphron, because it is known as a reuser of old S. madraspatanum nests. D i s t r i b u t i o n: Vietnam: Sai Gon, Vung Tau (DOLLFUSS 2016), Da Nang (TANO & KUROKAWA 2015), Hanoi, Thai Binh, Vinh Phuc, Nam Dinh, Son La, Hoa Binh, Ninh Binh, Thai Nguyen, Hung Yen, Quang Ninh, Bac Ninh, Lao Cai, Hai Duong, Phu Tho, Thanh Hoa, Nghe An, Quang Ngai, Kon Tum, Dac Lak.

Five provinces in which adult specimens of C. bengalense has been taken including Thanh Hoa, Nghe An, Quang Ngai, Kon Tum, and Dac Lak are new records for the Center Vietnam. Most of studied localities with an altitude of less than 400 m conducted at various habitats recorded the presence of C. bengalense. In all urban habitats C. bengalense occurred in abundance. It is, therefore, interesting to judge that this is an urban sphecid wasp. V a r i a t i o n: Examination results on 268 specimens of C. bengalense in the present study that are compared to those of HENSEN in 1988 reveal that the wasp has the following some variations: Female forms varied 13-17 mm in length of the body, and 9.5-11.5 mm in length of forewings; male forms 8.5-15 mm in length of the body and 6.5-10 mm in length of forewings. In most of specimens examined the pedicel and the scape are blue. In a female specimen collected from Thanh Hoa, the ninth and tenth flagellomeres of an antenna are yellow and brownish yellow, respectively. In most of cases the integument is without violaceous, excepting a female specimen collected from Thanh Hoa and a male specimen collected from Hanoi (the metasoma and legs are violaceous reflections). Anterior part of the metapleuron is with finely small punctate, and posterior part of that with denser, larger punctate., Published as part of Pham, Phong Huy, 2018, Chalybion bengalense (D, 1845) (Hymenoptera, Sphecidae) first reported in north Vietnam, pp. 681-685 in Linzer biologische Beitr��ge 50 (1) on pages 682-684, DOI: 10.5281/zenodo.4004358, {"references":["DAHLBOM A.

The sphecid fauna of French Polynesia, limited until now to Sceliphron caementarium (Drury), is increased by three species recently introduced in the Society Islands : Sceliphron laetum (Smith), S. curvatum (Smith) and Chalybion bengalense (Dahlbom). The presence of S. curvatum in French Polynesia considerably broadens the known distribution of this species which is native to Asia and introduced into Europe and both North and South America. Chalybion bengalense is also reported from New Caledonia for the first time, as well as Sceliphron laetum from Wallis and Futuna. The distribution, biology and potential impact of each species on the arachnofauna are discussed. An identification key to the Sphecidae of French Polynesia is provided., Les Aculéates de Polynésie française. III. Les Sphecidae, avec le premier signalement de trois espèces pour les îles de la Société (Hymenoptera). La faune des Sphecidae de Polynésie française, limitée jusqu’à présent à Sceliphron caementarium (Drury), est ici augmentée de trois espèces récemment introduites dans les îles de la Société : Sceliphron laetum (Smith), S. curvatum (Smith) et Chalybion bengalense (Dahlbom). La présence de S. curvatum en Polynésie française agrandit considérablement la répartition connue de cette espèce originaire d’Asie et introduite en Europe comme aux Amériques. Chalybion bengalense est également cité de Nouvelle-Calédonie pour la première fois, de même que Sceliphron laetum de Wallis-et-Futuna.

The paper presents new information about the occurrence of Chalybion omissum (KOHL, 1889) in central part of Balkan Peninsula (southern Bulgaria). Seven specimens were caught at 4 sites: N of Kurdzhali (UTM: LG61), Usstrem village (MG55), NE of Kalimantsi village (GL09), NE of Madzharovo (MG01).

Some aspects of the biology of the wasp Chalybion spinolae are documented. This includes behaviour relating to life cycles, nesting, mating, oviposition and prey interaction of this wasp. The physical appearance of the wasps and their prey are described and some measurements are given. The prey of C. spinolae are two species of spiders, Latrodectus indistinctus and Latrodectus geometricus (Araneae: Theridiidae). The observations spanned a period of 5 years, and involved approximately 200 wasp nests. This study serves to provide more observational information about the biology of the wasp and its predatory behaviour.

An animal's body size plays a predominant role in shaping its interspecific interactions, and, in encounters between two predators, often determines which shall be predator and which shall be prey. Spiders are top predators of insects, yet can fall prey to mud-dauber wasps that provision their larval nests with paralyzed spiders. Here we examined predator-prey interactions between Chalybion californicum (Saussure) (Sphecidae), a mud-dauber wasp, and Parasteatoda tepidariorum C. L. Koch (Theridiidae), a cobweb spider. We examined whether a spider's size influences its response to an attacking wasp, and report a size-dependent change in spider behavior: small-sized spiders fled, whereas medium- and large-sized spiders fought in response to wasp attacks. From the wasps' perspective, we examined whether spider size influences a wasp's hunting behavior and capture success. We found that wasps commonly approached small spiders, but were much less likely to approach medium and large spiders. However, wasp capture success did not vary with spider size. We also report a strategy used by Chalybion wasps toward cobweb spiders that is consistent with an interpretation of aggressive mimicry.

A new species of the blue mud-dauber genus Chalybion, C. sulawesii sp. n., is described from Sulawesi (Indonesia). The new species belongs in the C. fabricator species group, which up to now consisted of five rarely collected species. An identification key to the females of all species of the group is provided. Males are not keyed, because only a single male of the group, belonging to C. malignum, is known in addition to C. sulawesii. The last instar larva of C. sulawesii is described, although not all relevant characters could be reliably studied. We could show that the larva of the new species shows most of the relevant characters of the Sceliphrini, but differs from the larvae of other Sceliphrini studied yet in two characters. The majority of over 600 specimens of the new species have been reared from artificial trap nests, set up in different habitats and at different heights in the Lore Lindu National Park, Sulawesi. Of the 812 nests found, 606 provided adults, 64 provided pupae, and 40 provided larvae. 113 were just provisioned. The nesting activity of C. sulawesii showed a clear seasonality and was strongly influenced by the flowering plant diversity. Female activities were also significantly higher in lower strata. We assume that all three ecological factors studied influence the nesting activity of C. sulawesii via the spider prey density. (© 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)

Notes on nesting and gregarious behavior of the blue nest renting wasp Chalybion japonicum (Gribodo) are presented. Three focal nests, freshly attached to the walls of an abandoned house belonging to the mud dauber wasp Sceliphron madraspatanum were occupied by C. japonicum, suggesting that the wasp is a nest invader of S. madraspatanum. Aggregation of C. japonicum males on the string of the sack, which hung loosely beneath the ceiling, undoubtedly plays a role to help males finding females easily rather than by having to take flight. Discussion on relationship of occurrence between C. japonicum and C. bengalense is included. The new appellation “nest renting wasps” for Chalybion species is suggested.

The Podiinae are composed of Dynatus, Penepodium, Trigonopsis and Podium, the monophyly of which is strongly supported. They form the sister group of the monophylum comprising Chalybion and Sceliphron. Podium contains four probably monophyletic taxa, namely the fumigatum, the rufipes and the agile species groups and Podium eurycephalum sp. n. The new species is inferred to be the sister taxon of the rufipes + the agile group. There is less evidence for the monophyly of the fumigatum group, whereas that of the rufipes and the agile group is strongly supported by some striking autapomorphies. The detailed similarities in the habitus of the agile group and Trigonopsis are interpreted as an independent development as a result of adaptation to their hunting habits. The second ‘syntype’ of Podium agile Kohl hitherto regarded as destroyed, was rediscovered.
