Ebrechtella concinna

E. concinna has a wide distribution across the Oriental region. It has been recorded from Pakistan, India, Bangladesh, Myanmar, Thailand, Malaysia, Singapore, Indonesia (Sulawesi, New Guinea), and the Philippines.^[1][3]

Ebrechtella concinna is a medium-sized crab spider with the smaller males measuring approximately 2.5 millimeters in body length.^[4] The cephalothorax is yellowish-brown to brownish-yellow in coloration, with the front portion being broader and slightly truncated. There is often an arrow-head-shaped yellow marking on the back portion of the cephalothorax.^[4]

The abdomen is oval and moderately convex above, broadest toward the rear. In males, the upper surface is dull yellowish, covered with scale-like spots of silvery-white coloration. Five impressed spots form a triangle on the front half of the abdomen, with the forward-pointing apex surrounded by dull reddish yellow-brown coloration. Rows of reddish yellow-brown blotches extend backwards from these spots toward the spinnerets.^[4]

Females are generally lighter in coloration than males, with less distinct markings on the abdomen apart from the five impressed spots and patches near the spinnerets.^[4] The legs in both sexes are relatively long, with the first and second pairs being the longest and strongest. The legs are brownish-yellow with darker reddish-brown markings that give them an annulated appearance.^[4]
