The male has three strips on its abdomen while the female has a more complex pattern of dark bands and light patches.

The female epigyne has two shallow depressions and short seminal ducts that lead to long receptacles.

Mexcala synagelese is a jumping spider that was first described by the Polish arachnologist Wanda Wesołowska in 2009, one of over 500 species she identified during her career.

[2][3] The genus was a member of the tribe Heliophaninae alongside Pseudicius and Cosmophasis, which was absorbed into Chrysillini by Wayne Maddison in 2015.

The abdomen has a pattern of dark bands and four light patches that is typical of the genus.

[10] The copulatory openings lead relatively short seminal ducts and long receptacles.

[15][16] Like other jumping spiders, it is mainly a diurnal hunter that uses its good eyesight to spot its prey.

[18] The chelicerae have short thick spines on them which may be used for digging holes to act as underground hiding places.

[19] It uses visual displays during courtship and transmits vibratory signals through silk to communicate to other spiders.

[19] Mexcala synagelese lives in Angola, Democratic Republic of the Congo, Ivory Coast, Nigeria and Sudan.
