Beetles (Order Coleoptera) are the largest order of animals. a group insects that make up Coleoptera. Estimates total number living beetle species millions whose features it difficult to visually identify species. Currently, classification process is still carried out using direct observation and personal assumptions. CNN model ResNet50 one ResNet variants has 50 layers VGG16 utilizes convoluti...

In the current paper the first fossil representatives of leaf-beetles from the subfamily Lamprosomatinae (Coleoptera: Chrysomelidae) are described and illustrated from Upper Eocene Baltic amber: Succinoomorphus warchalowskii gen. et sp. nov., Archelamprosomius balticus gen. et sp. nov., and Archelamprosomius kirejtshuki sp. nov. A key to fossil Lamprosomatinae is provided.

Hypoaspis elegans sp. nov. was collected on adult female Oryctes elegans Prell. (Coleoptera: Scarabaeidae) in Bam, Kerman province, Iran. The new species is described and illustrated from adult females. Hypoaspis surii Khanjani et. al., 2013 is a junior synonym of Hypoaspis maryamae Joharchi & Halliday, 2011. A key to the Western Palaearctic species of Hypoaspis is presented. 

The species Rhoptrocentruspiceus Marshall (Hymenoptera: Braconidae) was reared from the larvae of the xylophagous beetle Psacotheahilarishilaris (Pascoe) (Coleoptera: Cerambycidae), an exotic pest of Ficus and Morus species native to eastern Asia. It was recorded in the north of Italy in September 2005. This discovery is the first report of this species as parasitoids of the yellow spotted long...

Copulation, observed in 6 species of Passalidae, occurred with one beetle up-side-down in relation to the other. In Odontotaenius they were end to end (known for Coleoptera only in Scolytidae); in Passalus they were venter to venter facing nearly the same direction (known for no other beetles and only for certain Diptera and Mecoptera among other insects).

The history of the genus Trichocnemis LeConte, 1851 (Coleoptera, Cerambycidae, Prioninae) is discussed. Its taxonomic status in relation to the genera Ergates Audinet-Serville, 1832 and Callergates Lameere, 1904 is clarified. The synonymy of Macrotoma californica White, 1853, Macrotoma spiculigera White, 1853, and Trichocnemis spiculatus LeConte, 1851 is confirmed. A key to all three genera and...

Ptomaphagus (s. str.) chenggongi sp. n. and Ptomaphagus (s. str.) tingtingae sp. n. (Coleoptera, Leiodidae, Cholevinae, Ptomaphagini) are described from Taiwan Island. In addition, a new subjective synonym is proposed, Ptomaphagus (s. str.) yasutoshii Nishikawa, 1993 = Ptomaphagus (s. str.) smetanai Perreau, 1996, syn. n. Relevant morphological characters of the examined Ptomaphagus species are...

A new Cotinis Burmeister (Coleoptera: Scarabaeidae: Cetoniinae: Gymnetini) species from Venezuela is described and illustrated. The new species is compared with Cotinis barthelemyi (Gory & Percheron) from Colombia. The Neotropical distribution of Cotinis is expanded to Venezuela. A revised key to the species of Cotinis is provided in both English and Spanish.
