MATERIAL. Holotype – ♂, Indonesia: central part of Sulawesi I., Sulawesi

Tengah Prov., Lore Lindu National Park, ~ 75 km SE of Palu City, environs of

Wuasa Vill., ~ 1000 m, 7–12.II 2011, A. Gorochov. Paratypes: 7 ♂, 2 ♀, same data as for holotype .

DESCRIPTION. Male (holotype). Body slightly smaller than in L. (P.) h.

wartabone . Coloration of body more or less similar to that of this subspecies, but pronotum yellowish with only three light brown spots in anterior half of disc, hind femur almost without darkened dots and with lighter (brown) areas on distal and dorsal parts, tibiae and tarsi almost yellowish but with brown to light brown marks on hind tibia similar to those of L. (P.) h. wartabone , tegmina and abdomen yellowish with a pair of brown lateral longitudinal bands on abdomen as well as with light brown anal plate and styles of genital plate, and cerci also light brown having apical parts and proximedial hooks slightly darker (almost brown; Figs 68, 69 ). External structure of body also similar to that of L. (P.) h. wartabone and L. (P.) h. hamatus ,

but posterior pronotal edge reaching apex of tegminal mirror (as in holotype of L. h.

wartabone ), left tegmen with distal part (including apical area) somewhat narrower than in L. (P.) h. wartabone (compare Figs 85 and 86 ), anal plate with lobules more similar to those of L. (P.) h. hamatus , cercus with apical part distinctly truncate (even barely notched) but with proximedial hook almost as in L. (P.) h. wartabone , and genital plate with short (as in L. h. hamatus ) distal thickenings and with straight posterior edge between styles ( Fig. 42 ). Genitalia membranous but with a pair of short semimembranous lobules located near each other ( Fig. 72 ).

Variations. Some males barely lighter or barely darker; sometimes their posterior pronotal edge slightly not reaching apex of tegminal mirror; genital plate varied from hardy concave to slightly convex between styles (in latter case, this plate rather similar to that of L. h. hamatus ; Fig. 43 ).

Female. General appearance as in males, but pronotum short and with three brown to light brown longitudinal bands, tegmina absent, metanotum with a pair of brown spots in posterolateral corners and with light brown median area turning into almost interrupted median band along dorsum of abdomen ( Figs 70, 71 ), and abdominal apex without any sexual specializations except for small and roundly triangular genital plate as well as moderately short but rather high and acute ovipositor lacking distinct denticles on dorsal and ventral edges.

MEASUREMENTS. Length (in mm). Body: ♂ 9–10, ♀ 10–11; pronotum: ♂

3.7–4, ♀ 2.6–2.7; tegminal parts visible behind pronotum, ♂ 0.8–1.2; hind femora:

♂ 9–10, ♀ 10–10.5; ovipositor 5.6–5.8.

COMPARISON. The new subspecies is distinguished from all the other subspecies of this species by the male cercus clearly truncate (even slightly concave) apically

(this cercal apex is rounded in L. h. hamatus and very thin in L. h. wartabone ), from

L. (P.) h. wartabone by a shorter (or absent) posteromedian notch of the male genital plate and by the presence of semimembranous lobules in the male genitalia,

and from L. (P.) h. hamatus with unknown genitalia by the body coloration less uniformly light (except for the hind leg which is similar to that of this subspecies but almost lacking distinct darkened dots on the femur; in L. h. hamatus , these dots are more distinct).

ETYMOLOGY. This subspecies is named after Lore Lindu National Park, in the eastern part of which it was collected.
