Onthophagus aeneopiceus d’Orbigny, 1902 (Coleoptera: Scarabaeidae: Scarabaeinae: Onthophagini) is recorded for the first time for Yemen and for the Palaearctic region. An integration into the key to the Onthophagini from the Arabian Peninsula (Ziani et al. 2019), is provided.

The genus Ochodaeus in Italy: taxonomy and distribution (Coleoptera: Scarabaeoidea: Ochodaeidae)
(2020)
The author provides a taxonomic, nomenclatural and distributional review of the genus Ochodaeus Dejean, 1821 (Coleoptera: Scarabaeoidea: Ochodaeidae) in Italy. All Italian populations have been confirmed to belong to a single species, O. chrysomeloides (Schrank, 1781). After the study of a syntype, O. cychramoides Reitter, 1892, formerly considered an Italian endemic, is confirmed to be a junior synonym of O.chrysomeloides. Type material of O. chrysomeloides is believed to be destroyed, therefore a neotype is here designated and deposited at the Natural History Museum of Vienna, Austria. A lectotype is here designated for O. cychramoides and deposited in the Hungarian Natural History Museum of Budapest, Hungary. The Italian distribution of O. chrysomeloides is given in detail and illustrated by a map.
Deep-sea ophiuroids were collected by the manned submersible ‘Shenhaiyongshi’ from the South China Sea at depths of 500–3550 m, in 2017 to 2020. A total of 18 species were identified, including three new species and eight new records, increasing the total number of species known from the South China Sea to 304. Most of the ophiuroids recorded from the South China Sea were found in shallow waters (77.9%) and a few of them occurred only in deep water (20.4%). Three new species are described as Ophiacantha aster sp. nov., Ophiomoeris petalis sp. nov. and Ophiopristis shenhaiyongshii sp. nov. We provide comprehensive descriptions of morphological features, including characteristics of the arm skeletons, and a phylogenetic analysis based on COI and 16S sequences. Overall intraspecific and interspecific genetic distance variations among the families found in this study were 0.5% to 2.47% and 1.16% to 44.16%, respectively, along the South Pacific region to the South China Sea. Our phylogenetic analysis suggested that COI partial genes resolved the interspecies complexity in the class Ophiuroidea better than 16S partial genes. The order Euryalida had low interspecies genetic distance variation within the class Ophiuroidea. The present study suggests a high probability that species of Asteroschema and Gorgonocephalus are more widely spread around the Indo-Pacific region than previously expected.
The subgenus Indonthophagus Kabakov, 2006 of Onthophagus Latreille, 1802 (Coleoptera: Scarabaeidae: Scarabaeinae: Onthophagini) is reviewed. A morphological definition of it is provided. A diagnosis, based both on external and internal characters, of the seven species deemed to belong to the group according to literature, is supplied. As a result, Onthophagus spinifex (Fabricius, 1781), previously placed with some uncertainty in the subgenus, is definitively excluded. A key to Indonthophagus species is also provided, as well as images of male, aedeagus and endophallus for each species. New country records of Onthophagus turbatus Walker, 1858 for Pakistan, Nepal and Bhutan are given.
