Supplementary description

Male ( Fig. 2I )

Similar to female (= holotype). Body narrower than in female. Eyes somewhat larger than in female, ratio of eye diameter to interocular space 1:4.5. Antennomeres IV to VII longer than in female, VIII to XI unavailable, ratio of antennomere lengths: 15: 10: 12:15: 15: 15: 12: -: -: -: -.

PRONOTUM. About 0.95 times as wide as head, nearly as long as wide. Elytra conjointly about 1.6 times as wide as pronotum, about 2.8 times as long as wide. Legs moderately slender; femora mostly straight; tibiae mostly straight, with basal part feebly arcuate; claws simple.

AEDEAGUS ( Fig. 4 C–D). Ventral process moderately expanded and rounded apically, apex curved inwards, basal part broad and extending inwards onto ventral side; dorsal plate of each paramere as long as ventral process, broad, apical margin rounded, with some hairs on it. Laterophyse very short, invisible in lateral view. Inner sac swollen, shorter than tegmen.

Remarks

This species should be attributed to the L. hanatanii species group as its morphological characteristics match the definition of this species group, in agreement with the cladogram ( Fig. 9 ); however, the female genitalia remain unexamined.

Distribution

China (Fujian Province).
