About Cupiennius Chiapanensis

Cupiennius Chiapanensis has red hairs on its chelicerae.The Banana Spider species in particular, Cupiennius chiapanensis, have bright red hairs on the chelicerae of their bodies. It is likely that the confusion was caused by the fact that Cupiennius chiapanensis was described only in 2006, so only a few arachnologists were aware of it. Another species, Cupiennius getazi, has also been transported to North America in bananas. Cupiennius live exclusively in Central America, where they are frequently found in banana shipments to North America.

Classification and description

This spider belongs to the Ctenidae family of the Order Araneae. In comparison with other species of the genus, this species is distinguished by the bright red or pale red pattern found on the chelicerae of the females and males. There are curves inside the lateral epigininal plates in the female. From the side, the male has an apophysisistibialis that is triangular from the side, long and thinner; the canal overlaps the terminal process, and the embolar base has keels marked on the top and bottom sides of its extension. 

Females are between 22mm and 27mm long. There is an orange-brown band behind the posterior eyes and continues across the carapace to reach the posterior border; the surface is covered with short white setae, except for small spots around the eye area and behind the posterior Short black setae cover these spots; the enditos are black with long white setae defining the leading edge, edged with white; long black setae curve from lateral edge of endito; light brown sternum with black edges, covered with long mixed black setae with small white setae; with small sets, coxa of the same color as the sternum, and opisthoma of a grayish brown color, covered with long and thick white setae. 

The back of the shirt has a black band with sinuous edges and a short white band in the middle. Long brown setae cover the sides of the opistosome. There is a dark longitudinal band extending from the epigastric sulcus to the spinettes and surrounding regions on the ventral surface. In the male, the carapace is an orange-brown color with a black band that starts behind the posterior medial eye and reaches the posterior edge; the surface is covered with small grayish setae that are separated by two black lines. An opistosoma generally covers with light brown setae, except for a few smaller dots. A dark band running from the epigastric sulcus to the area of the spinettes appears on the ventral surface.
