Material Examined. Holotype female (coll. no. Ch 2), CHINA, Hainan Island, Chengmai, Laocheng, Longji Hill, 24 April 2012, ATBarrion, JLACatindig and SCVillareal.

Diagnostic Features. Closely similar in body markings to N. snazelli Deeleman-Reinhold, 2001 but differs from the latter in terms of (1) large body size, (2) shorter legs, (3) wider eye width, (4) lyreshape trachea, (5) presence of a black posterior spot on abdomen, (6) tibia IV with only three ventral spines, and (7) ventral spine in metatarsus I almost as long as the segment itself.

Etymology. Name derived from the combination of the host plant and lyre-shaped trachea (pandan + lira) in Tagalog.
