Cheiracanthium torsivum, commonly known in Mandarin Chinese as "旋距紅螯蛛" or Twisted spur red chelate spider, is a species of yellow sac spider endemic to Taiwan. [1]
Description
[edit]C. torsivum have a yellowish-brown carapace and yellow abdomen.[1] Their abdomen has a pale grayish brown cardiac pattern. They are distinguished from similar species by the shape of the male's pedipalps; the palpal bulb sports a spiniform apophysis and distally-intorted cymbial spur. Females are distinguished from those of other species by dark, globular markings that can be seen through the tegument of the epigynum.
Distribution
[edit]C. torsivum is found in northern and southeastern Taiwan at elevations between 500m and 1800m.[1]
Etymology
[edit]"Torsivum," from the species name Cheiracanthium torsivum, means "spiral-twisted" and refers to the spiriform cymbial spur on the male's pedipalp.[1]
