Detection of cantharidin-related compounds in Mylabris impressa (Coleoptera: Meloidae) J. Venom. Anim. Toxins incl. Trop. Dis.
Nikbakhtzadeh,M. R.; Ebramihi,B..
Cantharidin is mainly found in the beetle families Meloidae and Oedemeridae (Insecta: Coleoptera) which are the natural producers of this terpene anhydride. Most studies to date have focused on cantharidin distribution in blister beetles, with few reports on recently found cantharidin-related compounds (CRCs). Using gas chromatography-mass spectrometry (GC-MS), the present work reported cantharidin and two CRCs, palasonin and cantharidinimide from Mylabris impressa stillata (Baudi, 1878) which was collected from Toyserkan county, Hamedan Province, Iran. Ionization provided mass spectra with characteristic fragments of cantharidin at m/z 96 and 128, demethylcantharidin at m/z 82 and 114, and cantharidinimide at m/z 70, 96 and 127. This is the first time...

Medically important beetles (insecta: coleoptera) of Iran J. Venom. Anim. Toxins incl. Trop. Dis.
Nikbakhtzadeh,MR; Tirgari,S.
This study focused on coleopteran species that are responsible for the emergence of recent cases of dermatological manifestations in Iran. To the best of our knowledge, five species of the family Meloidae and nine species of the genus Paederus are by far the only beetles recognized as medically important in Iran. The staphylinids consists of Paederus ilsae, P. iliensis, P. fuscipes, P. kalalovae, P. balcanicus, P. lenkoranus, P. littoralis, P. carpathicus, P. nigricornis, while the meloids are Mylabris impressa, M. guerini, Muzimes iranicus, Alosimus smyrnensis and Epicauta sharpi. Most cases of linear dermatitis in this country occur in areas bordering the Caspian Sea. This problem is caused by beetles of the genus Paederus which are present as adults...

Origin, transfer and distribution of cantharidin-related compounds in the blister beetle Hycleus scabiosae J. Venom. Anim. Toxins incl. Trop. Dis.
Nikbakhtzadeh,MR; Vahedi,M; Vatandoost,H; Mehdinia,A.
Cantharidin provides chemical protection for the coleopteran families Meloidae and Oedemeridae. In the present study, it was observed that cantharidin concentration in Hycleus scabiosae was slightly decreased from mated females (mean = 0.011 mg/mg of dry weight) to males (mean = 0.010 mg/mg) and considerably diminished in relation to virgin females (mean = 0.005 mg/mg). Significant concentrations of palasonin (21.69 ng/mg among virgins and 17.49 ng/mg in mated females) and palasoninimide (14.62 ng/mg in virgins and 9.17 ng/mg in mated females) were found in H. scabiosae. Palasonin, palasoninimide and cantharidinimide content of eggs were measured as 5.61, 7.69 and 7.80 ng/mg respectively. Surprisingly, males showed no trace of cantharidin-related compounds...

Revision of the genus Diaphorocera Heyden, 1863 (Coleoptera, Meloidae, Cerocomini) Naturalis
Turco, F.; Bologna, M.A..
Diaphorocera, a Saharo-Sindian genus belonging to the tribe Cerocomini, is revised and a new synonymy is proposed. A cladistic classification is proposed as well, on a set of adult morphological characters. The available bionomical records, both original and from literature, concerning phenology, elevation, habitat preference, and host plants, are summarised. Adult morphology of all species is described and figured, the catalogue of localities with maps of distribution is reported, and a biogeographical analysis is proposed.
Tipo: Article / Letter to the editor Palavras-chave: Coleoptera; Meloidae; Diaphorocera; Taxonomy; Phylogeny; Morphology; Faunistics; Biogeography; Palaearctic region; 42.75.

Types of Meloidae (Coleoptera: Tenebronoidea) housed at the Museo de La Plata entomological collection(Argentina) Rev. Soc. Entomol. Argent.
Campos Soldini,Paula M.; Suárez,Sonia M.; Lanteri,Analía A..
This contribution provides information on the type material of 36 species (eight genera) of Meloidae housed at the Museo de La Plata collection, collected in Argentina, Bolivia, Brazil, Paraguay, Peru and Uruguay. The types herein stated mainly correspond to species described by the Coleopterist Pedro Denier (20 spp), from 1930 to 1940, but also by the specialists Fritz Borchmann (6 spp), Federico G. C. Berg (7 spp) and Antonio Martínez (3 spp). We have examined almost 200 specimens regarded as types, but after the comparison of their label information with the original descriptions of the species, only 70 can be considered as true types (they are holotypes, allotypes, paratypes and syntypes). For each species we give the following information: original...
