Discussion. When again examining some specimens from the type locality of Larnaca (Larnaca) nigrifrons Pang, Zhang & Bian, 2023 , I found they are very similar to the holotype and paratypes of the species in details of the male and female abdomens, but slightly differ from the latter in coloration in the following: especially face and dorsal surface of head yellow brown ( Figs. 1A , 2A ), and the black pattern of pronotal disc not widened at anterior margin ( Figs. 1B , 2B ). Herein, I treated as an intraspecific variation of Larnaca (Larnaca) nigrifrons and gave a brief description.

Description. Male. Hind femora with 7–8 pairs of ventral spines. Subgenital plate with ventral surface elevated in middle area; basal margin straight, lateral margins of basal half convex, then strongly approaching from middle area; posterior margin with a V-shaped concavity, the lateral lobes obtuse with external margins more obliquer and longer than internal margins ( Fig. 1L ).

Coloration. Body yellowish brown. Face and dorsal surface of head yellowish brown ( Figs. 1A , 2A ), with a longitudinal blackish stripe on each side behind eye. Pronotum yellowish brown with anterior margins black followed by 1 pair of longitudinal blackish stripes, which reaching the posterior transverse sulcus ( Figs. 1B , 2B ).

Measurements (mm). Male: BL 16.11–17.64, PL 4.57–4.78, HFL 9.36–9.53, TL 1.93–2.05; Female: BL 10.13–19.32, PL4.13–5.11, HFL 9.15–11.07, TL 1.87–2.0, OvL 9.69–11.51.
