Macrothele is a genus of mygalomorph spiders in the family Macrothelidae, and was first described by A. Ausserer in 1871.[3] It is the only genus in the family Macrothelidae, and most species occur in Asia, from India to Japan, and Java, with four found in Africa, and two in Europe.[1] The name is derived from Ancient Greek μακρός ("makro-"), meaning "big", and θηλή ("thele"), referring to the spinnerets.[citation needed]
Description
Spiders of this genus are fairly large, with females of some Chinese species ranging from 1 to 3 centimetres (0.4 to 1.2 in) in body length. Males are smaller, sometimes only half that length.[4] Macrothelids can be distinguished from other mygalomorph spiders by their larger posterior sigillae on the sternum, and the arrangement of the rows of teeth on the margin of the chelicerae: larger front-facing margin and smaller rear-facing.[5]
These spiders build tube-webs or funnel-webs under rocks or logs, or in crevices in the ground.[4]
Taxonomy
The genus Macrothele was erected by Anton Ausserer in 1871, with the type species being Macrothele calpeiana, formerly Mygale calpeiana.[1] [citation needed] Ausserer placed the genus in the then very broadly defined family Theraphosidae. It was later placed in the Dipluridae and the Hexathelidae before being transferred to the Macrothelidae in 2018.[1] A molecular phylogenetic study in 2018 suggested that Macrothele was a distinct, early diverging lineage within the Mygalomorphae. Accordingly, Simon's subfamily Macrothelinae was elevated to the family Macrothelidae. There is some doubt if the western and eastern species should be grouped in the same genus.[6]
