Diagnosis. L. nicobarensis can be easily separated from other Chinese Lispe by its shining black body color and the higher locaton of vibrissae (at half distance between oral margin and base of antenna). Other diagnostic characters include: frons black, parafacial and gena with silver pruinosity; few setae on thorax and legs; dc 0+1.

Male: body length 4.2–4.5 mm. Fore femur with 2 or 3 pv; mid femur swollen on basal half; hind femur with 3 long and curled v on basal half (the basal one more or less situated on av surface), with 1 short pv row; hind tibia short, with 1 v row; abdomen black, tergite 4 with a pair of lateral white spots and sternite 4 modified, with a asymmetric pointed process on right posterior side ( Fig. 6D ); apex of abdomen with curled setulae ( Fig. 5F ); cerci merged into one plate at 2/3 upper side, with a curved edge at lower side ( Fig. 6C ).

Female: body length 6.0– 6.2 mm. Syntergite 1+2 and tergites 4 and 5 with silvery white lateral spots; and tergite 4 with a slim white median stripe posteriorly ( Fig. 7 ).

Remarks. Wei & Yang (2007) published L. leigongshana from southern China. Their description and illustration ( Wei & Yang, 2007: 497–498) show that all main characters of L. leigongshana fall into the characterization of L. nicobarensis : 1) thorax shining black without dense pruinosity; 2) dc 0+1; 3) fore femur with 3 pv on apical half; 4) mid femur distinctly thinner on apical half; 5) hind femur with 3 curled and long v; 6) sternite 5 with a process on the right side (actually, it is sternite 4); and finally, by comparing the male terminalia we can observe they have same shape ( Fig. 6 ). We compared the terminalia dissected from specimens recognized here as L. nicobarensis with the original drawings of L. leigongshana by Wei & Yang (2007). The comparisons above convinced us to synonymize L. leigongshana under L. nicobarensis .

Distribution. Widespread from northern Australia to eastern India. Distribution in CHINA: Fujian, Guangdong, Guangxi, Taiwan and Yunnan.
