I spot another jumping spider, and this one I caught around mid-June east of my town, Lhokseumawe. I'm pretty sure this is another type of jumping spider I've never seen in the past.
Based on the spider's characteristics, I'm fairly certain it's a Nicylla sundevall, the only species of the genus Nicylla found in Sumatra, as first described by Tamerlan Thorell in 1890.
The jumping spider is black with shimmering blue stripes on its head and four front legs, while half of the four rear legs are transparent. Blue stripes in a V-shape are found on its abdomen. With its two longer front legs, I'm confident that the spider is a male.
