diagnosis
Diagnosis. Males of N. lachonta n. sp. resembles those of N. buruti n. sp. by the length of copulatory bulb (tegulum + embolus) being more than two times the palpal tibia length (Figs 8 B – C; 9 B – C), differing by having a slender large bulb with a wider tegulum basal section (Fig. 8 J). The strongly swollen palpal tibia, 1.8 times wider than proximal and distal portions (Fig. 8 B – C) is also diagnostic.
