Cosmophasis lami, also known as the Lami Beach northern jumping spider, is a species of jumping spider in the genus Cosmophasis, probably native to South East Asia and some pacific islands, and possibly introduced to Japan and Okinawa Islands by humans.[1] It was first described by Berry, Beatty & Prószynski in 1997 and has one synonym, Cosmophasis squamata (Saaristo,2002)[nb 1][2][3][4] Both the female and the male have been described.
Description
Exact description may vary, but the species displays sexual dimorphism, with females' coloration being more vibrant. Adult C. lami's carapace is orange-brown.[5] a dark-brown area around the eyes, and coated in orange hairs and the clypeus is orange-brown. The males are coated in orange hairs, cephalothorax are dull orange, abdomen is orange and slender, clypeus orange-brown, black apex and spinnerets and a dark-brown area around the eyes.[2][6] Females are almost similar, with the only difference being a grayish brown sternum and different abdominal markings.[2] It is similar to C. hortoni, but is smaller, the chelicerae shorter, with a longer embolus of the male palp, which is southeast from the bulb.[7] There is a iridescencent morph.[8]
Entomology
The first recorded specimen of C. lami is a male collected on 3 May 1987 by Joseph Beatty and E.R. Berry from Fiji on shrub foliage in Lami, Fiji and the species was named after it (the location). The name was first published in January 1997 along with Ascyltus similis, Ascyltus rhizophora, Bavia fedor, Bavia sonsorol, Cosmophasis arborea, Cosmophasis muralis, Flacillula nitens, Ligurra opelli, Thorelliola dumicola, and Trite ponapensis.[9] Cosmophasis lami has no subspecies.[citation needed]
Distribution
Considered the most widely distributed salticid from Cosmophasis, Cosmophasis lami was first observed in Fiji and is native to South East Asia and Cocos Islands, Mauritius, and the Marquesas Islands.[1][9][10][11] The World Spider Catalog says that it is introduced to Seychelles, Marquesas Island , Society Islands and Fiji. [4]In 2013, it was first recorded in Japan by Tatsumi Suguro.[2] Eight years later, it was recorded in Okinawa Island on roadside vegetation in an residential area, probably by artificial introduction.[2] In 2021, specimens were recorded in Taiwan.[4]
Ecology
Although little is known about its ecology,[10] it is known that Cosmophasis lami are peridomestic carnivorous arthropod predators.[12] Males do not exhibit stereotypical behavior while in a fight between other males in a study.[8] Common behaviour of the males include vertical “pumping” movements of the pedipalps and continual vertical movement of the abdomen.[8]
Relations with humans
Cosmophasis lami is called homura-haetori (flame fly-removal) in Japanese,[2] and is not considered a pest.
