Mexcala fizi

Mexcala fizi 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.{{cite web|author=World Spider Catalog|year=2017|title=Mexcala fizi Wesolowska, 2009|website=World Spider Catalog|publisher=Natural History Museum|place=Bern|url=http://www.wsc.nmbe.ch/species/30837|version=18.0|access-date=9 June 2017}}{{sfn|Wiśniewski|2020|page=6}} She allocated the species to the genus Mexcala, first raised by George and Elizabeth Peckham in 1902 as part of a thorough revision of the genus.{{sfn|Wiśniewski|2020|page=6}}{{sfn|Wesołowska|2009|page=149}} The genus was a member of the tribe Heliophaninae alongside Pseudicius and Cosmophasis, which was absorbed into Chrysillini by Wayne Maddison in 2015.{{sfn|Maddison|Bodner|Needham|2008|page=57}}{{sfn|Maddison|2015|page=252}} The tribe is a member of the clade Saltafresia within the subfamily Salticoida.{{sfn|Maddison|2015|page=278}} A year later, in 2016, Jerzy Prószyński allocated the genus to the Heliophanines group of genera, which was named after the genus Heliophanus. The genera share characteristics, including having a rather uniform, mainly dark appearance.{{sfn|Prószyński|2017|page=29}} The species itself has a name that is derived from Fizi, the name of the town {{convert|9|km}} away from the place where the first example was collected.{{sfn|Wesołowska|2009|page=162}}

Like all Mexcala spiders, the species is slender and medium-sized.{{sfn|Wesołowska|2009|page=152}} The female has a dark brown hairy carapace that ranges from {{convert|2.7|to|2.9|mm|in|abbr=on}} long. The chelicerae has a serrated front edge and a single tooth. The labium, maxilla and sternum are light brown. The abdomen is between {{convert|3.1|and|3.4|mm|in|abbr=on}} long and brown with a pattern of three black bands in the middle. The spider has long thin legs and brown pedipalps.{{sfn|Wesołowska|2009|page=162}} The palpal bulb is convex and the tibial apophysis is short.{{sfn|Wesołowska|2009|page=163}} The embolus is fixed to the tegulum.{{sfn|Maddison|2015|page=252}} The female has not been described.

Like many jumping spiders, Wesołowska and Tamás Szűts noted that Mexcala spiders mimic ants.{{sfn|Wesołowska|Szűts|2001|page=523}} It lives amongst various different species of ant and ant-like wasp that it mimics, and preys upon.{{sfn|Wesołowska|2009|page=152}}{{sfn|Pekár|Petráková Dušátková|Haddad|2020|page=6}} Like other jumping spiders, it is mainly a diurnal hunter that uses its good eyesight to spot its prey.{{sfn|Richman|Jackson|1992|page=33}} It attacks from the front and captures its prey behind the head.{{sfn|Pekár|Petráková Dušátková|Haddad|2020|page=5}} The chelicerae have short thick spines on them which may be used for digging holes to act as underground hiding places.{{sfn|Wesołowska|2009|page=153}} It uses visual displays during courtship and transmits vibratory signals through silk to communicate to other spiders.{{sfn|Richman|Jackson|1992|page=34}}

Mexcala spiders can be found across Africa and the Arabian peninsula.{{sfn|Wesołowska|2009|page=153}} Mexcala fizi was first discovered in Sud-Kivu District in Democratic Republic of the Congo at an altitude of {{convert|1320|m|ft|abbr=on}} above sea level, the holotype being collected in 1958. The first example found in Tanzania was seen in 1957 near Seronera in Serengeti National Park at an altitude of {{convert|1500|m|ft|abbr=on}} above sea level.{{sfn|Wesołowska|2009|page=162}}
