Equus (genus)
Equus is a genus of mammals in the family Equidae, which includes horses, donkeys, and zebras. Within Equidae, "Equus" is the only recognized extant genus, comprising seven living species. The term equine refers to any member of this genus, including horses. Like Equidae more broadly, "Equus" has numerous extinct species known only from fossils. The genus most likely originated in North America and spread quickly to the Old World. Equines are odd-toed ungulates with slender legs, long heads, relatively long necks, manes (erect in most subspecies), and long tails. All species are herbivorous, and mostly grazers, with simpler digestive systems than ruminants, but able to subsist on lower-quality vegetation.
Empusidae
Empusidae belong to the superfamily Mantoidea, (“higher” mantises), together with Mantidae and Hymenopodidae [5]. Phylogenetic studies place Empusidae as a sister group to Hymenopodidae. Empusidae and Hymenopodidae are in turn placed as sister groups to all other ambush mantids [3]. There are two subfamilies within Empusidae, Blepharodinae and Empusinae. The Blepharodinae subfamily holds three genera, Blepharodes, Blepharopsis and Idolomantis. The Empusinae subfamily is divided into two tribes, Empusini and Idolomorphini. The Empusini tribe holds five genera, Dilatempusa, Empusa, Gonglyus and Hypsicorypha (see List of mantis genera and species). The Idolomorphini tribe holds the three remaining genera,Hemiempusa, Idolomorpha (see List of mantis genera and species) and Chopardempusa [6]. The latest phylogeny was revised by Svenson et al. 2015 [1].Svenson, Gavin J., et al.
