Description. Length (from apex of vertex to tip of fore wings): 3 (N=1), 15.0 mm; Ƥ (N=1), 15.5 mm . Body length (from apex of vertex to tip of anal tube): 3, 9.1 mm ; Ƥ, 9.4 mm . Colour. General color ochraceous; frons with anterior and lateral margins and medial line suffused with orange stripes, apex of rostrum, eyes and antennal pedicel, suffused with brown; vertex and pronotum dark green, vertex with posterior marginal carinae, pronotum with median disc and lateral portion, and mesonotum with median carina, all suffused with orange; fore wings hyaline, veins and stigma brown; fore tibia and mid tibia with apices and bases, hind tibia with bases, lateral spines with apices, long stripes on hind femora and tarsi with apical segments all suffused with black. Head and thorax . Head ( Figs. 1 A, 2A) projecting beyond eyes for 0.39 times longer than length of eye. Frons ( Figs. 1 B, 2C) without median carina, lateral carinae slightly carinate, disc smooth, median length 1.02 times longer than greatest width and 1.45 times longer than breadth at anterior margin of frons. Vertex ( Figs. 1 A, 2A) distinctly shorter than greatest width (0.37:1), slightly longer than pronotum at midline (1.11:1). Pronotum ( Figs. 1 A, 2A) distinctly shorter than mesonotum in midline (0.18:1). Mesonotum ( Figs. 1 A, 2A) with median carina uniting with lateral carinae; lateral carinae curvulate for their posterior half and converging sharply anteriorly in anterior half; pronotum and mesonotum together medially 5.9 times as long as median length of vertex. Fore wings ( Figs. 1 A, 2D) hyaline, surpassing extremity of abdomen about 0.65 times as long as length of body and 2.8 times as long as maximum breadth; with 18–20 apical cells. Hind tibiae usually with 4 distinct lateral spines, if with 5 spines then often on one leg only and with basal spine very fine. FIGURE 3.

Male genitalia. Xth segment with lateroventral margin with two pair of distinctly long spines, one pair situating at apical 1/3 and other situated at level of extremity of apical dorsal margin ( Figs. 2 F, 2H); anal style short and small, only slightly surpassing extremity of apical dorsal margin of anal tube. Left gonostylus ( Figs. 2 F, 2G, 2I ) 3.18 times as long as maximum breadth in lateral view (see Fig. 2 F), basal dorsal edge with a dorsoposteriorly directed prominence, followed by a finger-like, dorsoposteriorly directed process (see Fig. 2F). Right gonostylus 3.23 times as long as maximum breadth in lateral view, basal dorsal edge with a clublike, dorsolaterally directed process (see Fig. 2 G). Periandrium ( Figs. 3 A, 3B) with apical margin with a thin and sinuous branched process at ventral side, with apical part curved dorsally, process forked at middle part, protruding anteriorly, apex curved posterodorsally. Aedeagus ( Figs. 3 A, 3B) with a long, sinuous process at basal part, lateroventrally directed, with ventral margin with many denticles, apical part curved posterodorsally; basal 1/4 to 1/2 of aedeagus with three projections at left side: one lamelliform projection I small and short, directed dorsally at dorsal side, one lamelliform projection II relatively long, stout and twisted, directed ventrally at ventral side and one global projection III arising from middle part between two lamelliform projections; with a tooth-like dorsoposteriorly directed prominence arising from dorsal edge at right side; endosoma with three projections: right projection abruptly extended into a falciform plate, directed dorsally, ventral projection spine-like, directed anteroventrally, and apical projection reaching to level of dorsal margin of anal tube, stout and cylindrical, apical part twisted with apex oblique and lanceolate in form, with margin denticulated. Female genitalia . Gonopophyses VIII ( Figs. 3 C, 3F) asymmetrical at base in ventral view ( Fig. 3 F), left produced into lobe with large globular apex, right produced into lobe with smaller globular apex. Gonopophyses IX ( Fig. 3 E) with apical ends not confluent; gonospiculum ( Fig. 3 E) slightly shorter than median length of triangular part (0.95:1), indistinctly flattened laterally. Gonoplacs ( Figs. 3 C, 3D, 3F) with 4 teeth at dorsal margin, dentition complex, not forming one line, with 3 outer teeth at apical part, followed by 12–13 teeth from apical to ventral margin. Sternite VII with median part sinuous at ventral side ( Fig. 3 F). Material examined. Philippines : 13, P. I. MISAMIS OR., Mt. Empagatao, 1050–1200 m , Rain forest, 19–30.IV.1961 , H. Torrevillas ( BPBM ); 1Ƥ, P. I., MINDANAO, Agusan, Esperanza, 4–11.XI.1959 , C. M. Yoshimoto ( BPBM ). Remarks. L. philippina was described from a single specimen ( holotype ).
