DESCRIPTION. Female (nova). General appearance similar to that of female of L. bispinosa , but: body more diverse in size, from rather large for this genus to moderately small;

rostral tubercle usually with darker (brown to dark brown) apical and ventral parts; scape and pedicel often partly darkened; antennal flagellum almost always uniformly light brown;

clypeus with upper half dark brown to black ( Fig. 4 ); all femora with darkened apical parts;

all tibiae with darkened basal parts and more or less darkened dorsal surfaces; rostral tubercle somewhat shorter (not reaching apex of scape) and with slightly more rounded apical part (as in Figs 4, 5 ); genital plate with median and posterior parts distinctly more convex (these parts often somewhat darker than rest of this plate; Fig. 29), with shallowly rounded or almost angular posteromedian notch, and with intermediate (between L. bispinosa and L. buonluoiensis ) length of posterolateral lobules (compare Figs 19, 27, 29); ovipositor as in Fig. 30.

MEASUREMENTS. Length (in mm). Body: ♂ 25–33, ♀ 24–32; pronotum: ♂ 10.2–12,

♀ 7.5–10; tegmina, visible parts: ♂ 2.8–3.5, ♀ 0.6–1; hind femora: ♂ 15.8–20, ♀ 15–19;

ovipositor 9.5–11.

COMPARISON. From the other congeners, L. natalicium differs in the upper half of clypeus strongly darkened, pronotal lateral lobe with a ventral denticle, male tegmina almost as in L. bispinosa (i.e. more protruding beyond pronotum than in L. buonluoiensis ; Fig. 5 ),

last male tergite almost not bilobate (i.e. with very small posteromedian notch and narrow concavity before it; Fig. 28), male cerci with the apical part of dorsal branch having three rather thick and short angular lobules directed medially, and/or some characters of the female genital plate named above.

Figs 14–30. Liaromorpha : 14–20 – L. bispinosa sp. n.; 21–25 – L. nitida Ingr. ; 26, 27 –

L. buonluoiensis Gor. ; 28–30 – L. natalicium Gor. Male abdominal apex from above (14,

21), from below (15, 22), from side (16, 23) and from behind (18, 25, 26, 28); male genital sclerite (sclerites) from above (17, 24); female genital plate from below (19, 27, 29); ovipositor from side (20, 30).

REMARK. This species, described from the Bokor National Park ( Cambodia), is recorded from Vietnam and from a new locality in Cambodia for the first time. Vietnamese specimens are usually larger than Cambodian ones and may belong to a new subspecies, but this question is in need of additional study.
