Ascyltus are a genus of jumping spiders in the family Salticidae that was first described by Ferdinand Anton Franz Karsch in 1878.[2] As of 2020, this Genus contained 10 species [3]and is a part of the largest family of spiders. The Ascyltus spiders utilize their vision in courtship, hunting, and navigation. Ascyltus are usually large to medium sized Salticids and often move relatively slow. However, they are capable of agile jumps when moving, hunting, or to avoid predators. They have well developed book lungs and tracheal systems, and they are capable of utilizing both systems (bimodal breathing). Ascyltus have four pairs of eyes. Three secondary pairs and one pair that is moveable. Like other spiders in their family, the anterior median pair is particularly large. One distinguishable characteristic of the Ascyltus include their antero-lateral carapace, which is iridescently colored.[4]
Distinguishing characteristics
Ascyltus are relatively large to medium sized salticids. They are famous for their remarkably large eyes, which function to help them spot potential prey from longer distances. Distinguishable from other Pacific salticids by the antero-lateral carapace, which is iridescently colored. The antero-lateral carapace is widened in adults and late juveniles alike. The eyes in three rows instead of four and the first metatarsal spines being absent. [4]
Size
- Males average 13-19 millimeters
- Females average 16-20 millimeters
Habitat
The majority of Ascyltus live in the oceania, oceanic islands, and pacific islands. Some Ascyltus have also been found in the Hawaiian islands.[5]
Diet
Ascyltus are carnivorous, so their diet mainly consists of insects around the tropical region. They capture the majority of their food by stalking or hunting prey. This includes many flies, crickets, and small grasshoppers.
Hunting methods
The Ascyltus jumping spider relies on visual stimuli when catching prey. The anterior-lateral eyes function to track moving objects. The anterior-median eyes are essential for the stalking of prey because of their telescopic abilities.[6]
Species
As of June 2019[update] it contains ten species, found only in Oceania, on the Pacific Islands, and Sulawesi:[1]
- Ascyltus asper (Karsch, 1878) – Australia (New South Wales), New Caledonia
- Ascyltus audax (Rainbow, 1897) – Tuvalu (Funafuti)
- Ascyltus divinus Karsch, 1878 – Australia (Queensland), Fiji
- Ascyltus ferox (Rainbow, 1897) – Tuvalu (Funafuti)
- Ascyltus lautus (Keyserling, 1881) – New Guinea, Samoa
- Ascyltus minahassae Merian, 1911 – Indonesia (Sulawesi)
- Ascyltus opulentus (Walckenaer, 1837) – Tonga
- Ascyltus pterygodes (L. Koch, 1865) (type) – Pacific Is.
- Ascyltus rhizophora Berry, Beatty & Prószyński, 1997 – Fiji
- Ascyltus similis Berry, Beatty & Prószyński, 1997 – Fiji, Samoa
