'''''Sia ferox''''' (also known as Riokku (リオック, loanword from the Indonesian name) or Obakekorogisu (オバケコロギス, "[[Obake]] raspy cricket") in Japan) is a [[species]] of [[cricket (insect)|cricket]] that lives in Indonesia. It belongs to the [[family (biology)|family]] [[Stenopelmatidae]] and the [[genus]] ''[[Sia (insect)|Sia]]''.<ref>[http://orthoptera.speciesfile.org/Common/basic/Taxa.aspx?TaxonNameID=1132187 ''Sia ferox'']</ref>
==Appearance==
The length is {{convert|65|-|80|mm}}. Although its basic form is similar to other [[Stenopelmatoidea]], it is relatively elongated. Its body-color is brown. The female has a rudimentary [[ovipositor]], unlike true [[Gryllacrididae]] or [[Anostostomatidae]] species. It is similar to [[Jerusalem cricket]]s, but it is the only species of Stenopelmatidae that lives in Indonesia, and the related species ''[[Sia incisa]]'' occurs in [[Malaysia]].
==Ecology==
The species is a [[nocturnal]] predatory cricket that presumably [[predation|preys]] on other small organisms found in the rainforest litter such as other [[arthropod]]s including [[spider]]s, smaller [[Cricket (insect)|crickets]] and [[grasshopper]]s.<ref>{{Cite web |title=Bulldog Raspy Cricket (Sia ferox) - JungleDragon |url=https://www.jungledragon.com/specie/26339/bulldog_raspy_cricket.html |access-date=2024-04-22 |website=www.jungledragon.com |language=en}}</ref> Like other [[Stenopelmatidae]] species, ''Sia ferox'' usually hides in its burrow during the day. At night, it comes out from its burrow and searches for prey. The detailed ecology of ''S. ferox'' is not known due to insufficient research.
