Getting more pieces of Mosaics on West Sumatran Spiders (Araneidae): Inventory from Mount Marapi in West Sumatra

Abstract

Abstract The field survey had been regulated from September until December 2019 by deploying an array of hand collection, sieving, sweeping and beating techniques applied simultaneously along three pairs of 120 m transect positioned at both sides of mountain hiking tracks. This exploration aimed to survey and inquiry the diversity of spiders (Araneidae) in Mount Marapi, West Sumatra Province. There were 25 spider individuals collected in this study; they were then identified and classified into 15 species which associated with 8 genera. Gasteracatha was a genus with the most species found (3 species, 9 individual), followed by Argiope (3 species, 7 individual) and Cyclosa (3 species, 5 individuals). Without minimizing the role of other collecting techniques, the hand collection technique was seemed to be more effective in doing the inventory on either spider individuals or species than the beating, sweeping or sieving techniques. The latter technique yielded the least result in this study.
