Morphological traits of spiders (Araneae) and ants (Formicidae) collected from Northern Ghanaian mango orchards and forest savanna

This dataset contains the values of morphological traits measured from mature spiders and ants collected in northern Ghana October/November 2022. The six measured morphological traits for spiders are Total body length (mm), Prosoma length (mm), Prosoma width (mm), Prosoma height (mm), Tibia I length (mm) and Fang length (mm) and the four measured morphological traits for ants are Total body length (mm), Head length (mm), Scape length (mm) and Eye Distance (mm).

Methods
Adult spiders and ants were sorted from standardized pitfall and Malaise trap material collected in Oct/Nov 2022 Tamale, Ghana. Individuals were identified as accurate as possibly to species, morphospecies, genus etc. by Luís Crespo (spiders) and Veikko Yrjölä (ants). A maximum of ten individuals (5 females and 5 males or 10 worker ants) were selected randomly and mesured under microsope. The six measured morphological traits for spiders were Total body length (mm), Prosoma length (mm), Prosoma width (mm), Prosoma height (mm), Tibia I length (mm) and Fang length (mm) and the four measured morphological traits for ants were Total body length (mm), Head length (mm), Scape length (mm) and Eye Distance (mm). Finally, selected and measured spiders were preserved in the ethanol collection at the Finnish Museum of Natural History and the rest of the material was sent back to University for Development Studies, Ghana. All occurences are digitized and available separately on GBIF.
