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

## Description of the data and file structure

Pitfall and Malaise trapped ants and (mature) spiders from northern Ghana were identified and measured for biodiversity research of SustInAfrica WP3 ([https://sustinafrica.com/](https://sustinafrica.com/)). Sorting of bulk material, identification of ants and all of the morphometric measures were executed by VY (University of Helsinki) while spider identification was executed by LC (University of Helsinki). A maximum of five male and five female spiders were measured for total body length, prosoma length, prosoma, width, prosoma height, tibia I length and fang length in millimeters. A maximum of five worker ants were measured for total body length, head length, scape length and distance between the compound eye and the base of...,

本数据集收录了2022年10月/11月在加纳北部采集的成熟蜘蛛与蚂蚁的形态性状测量值。蜘蛛的六项测量形态性状为：总体长（mm）、头胸部（Prosoma）长（mm）、头胸部宽（mm）、头胸部高（mm）、第一胫节（Tibia I）长（mm）以及螯肢长（mm）；蚂蚁的四项测量形态性状为：总体长（mm）、头长（mm）、柄节（Scape）长（mm）以及复眼间距（Eye Distance）（mm）。

成熟蜘蛛与蚂蚁样本从2022年10-11月在加纳塔马利采集的标准化陷捕器（pitfall trap）与马氏陷阱（Malaise trap）样本中分拣得到。样本由Luís Crespo（蜘蛛类群）与Veikko Yrjölä（蚁类类群）尽可能精准地鉴定至物种、形态种、属等分类阶元。随机选取最多10个个体（5雌5雄蜘蛛，或10头工蚁），在显微镜下完成测量。

经选取与测量的蜘蛛样本保存于芬兰自然历史博物馆乙醇馆藏中，其余样本则送回加纳发展研究大学。所有记录均已数字化，可在GBIF（Global Biodiversity Information Facility）平台单独获取。

## 数据与文件结构说明

本数据集针对SustInAfrica WP3项目（[https://sustinafrica.com/](https://sustinafrica.com/)）的生物多样性研究需求，对加纳北部通过陷捕器与马氏陷阱采集的成熟蚂蚁及蜘蛛样本进行了鉴定与形态测量。批量样本分拣、蚂蚁鉴定及所有形态测量工作由赫尔辛基大学的VY完成，蜘蛛鉴定工作由赫尔辛基大学的LC完成。

针对蜘蛛，随机选取最多5雄5雌个体，测量其总体长、头胸部长、头胸部宽、头胸部高、第一胫节长及螯肢长，单位为毫米。针对蚂蚁，最多选取5头工蚁，测量其总体长、头长、柄节长以及复眼基部间距……
