Eyes: eight, rounded, all approximately equal size; ocular region on protuberance; AME separated by their diameter, AME-LE touching; ALE-PLE contiguous, LE-PME separated by their diameter; PME separated by their radius. Abdomen: oval, dark grey chevron pattern flanked by white and with white patches (Figs 113, 114). Legs: femur I dark orange-brown; femur II light brown with dark band basally and apically; femora III-IV light yellow with dark ventral band basally, medially and apically; tibiae and metatarsi I-IV light yellow with dark band apically, tarsi light yellow; femur and tibia I enlarged, metatarsus I slightly curved.
