(Fig. 2)
Type material. Holotype: male (Fig. 2 A, B), CAMBODIA, Siem Reap, Kbal Spean, light trap, 28 V 2005, I. Var & P. Grootaert (IRSNB). Paratypes: 1 female, same data as holotype (IRSNB); 1 female, CAMBODIA, Siem Reap, Angkor Tom, light trap, 18 VII 2003, D.R. Jump (IRSNB); 1 female (Fig. 2 E, F), CAMBODIA, Siem Reap, Kbal Spean, Phom Kulen National Park, 24 VII 2004, P. Grootaert (IRSNB); 1 female, CAMBODIA, Siem Reap, Angkor Tom, 25 VII 2004, P. Grootaert (IRSNB); 1 male, CAMBODIA, Siem Reap, Angkor Thom, VIII 2006, D.R. Jump (IRSNB).
Etymology. The new species is named for the country of Cambodia, from which the types were collected.
Measurements of types (in mm, 2 males, 3 females). Length of body: male 16.7 (15.2–18.2), female 20.1 (19.9–20.2); width of head including eyes: male 7.0 (6.8–7.1), female 7.5 (7.2–7.6); wing span: male 48.4 (47.0–49.8), female 52.8 (51.2–54.9).
Diagnosis. This species is closely allied to Lemuriana apicalis from India in body pigmentation as well as body size but is distinguished by the following characters: fore wing without infuscation (L. apicalis with apical fuscous spot on fore wing); coastal vein of fore wing castaneous (ochraceous in L. apicalis); male operculum mostly ochraceous except fuscous lateral and inner margins (operculum with castaneous margins or entirely fuscous in L. apicalis); male abdomen with a pair of lateral white marks only on tergite 3, transverse white fascia along anterior margin of tergite 3, and sometimes indistinct transverse white fascia along anterior margin of tergite 7, all consisting of silvery hairs with white pollinosity (in L. apicalis, this kind of lateral white mark larger and extending to tergite 2, and transverse fasciae present on tergite 7 and sometimes 6, not on tergite 3). In male genitalia, shapes of uncus, aedeagus, and processes on ventrolateral margin of pygofer different.
Description of male (Fig. 2 A, B). Head black with small triangular median light ochraceous spot on posterior margin of head. Distance between lateral ocelli and compound eyes about as long as or slightly longer than distance between lateral ocelli. Postclypeus considerably swollen. Antenna brown to dark brown. Postclypeus castaneous with black medial area and black transverse fasciae along transverse grooves except marginal areas. Anteclypeus black. Rostrum dark ochraceous with black apical area; reaching anterior margin of hind coxae. Lorum black except dark ochraceous anterior margin. Gena black.
Inner area of pronotum reddish castaneous with medial longitudinal black fasciae. Pronotal collar mostly black except ochraceous lateral areas. Lateral pronotal collar not developed. Mesonotum black with following indistinct castaneous marks: a pair of paramedian marks surrounding submedian sigilla, extending posteriad to be connected to anterior angles of cruciform elevation; a pair of large lateral spots; three to four delicate transverse branches derived from paramedian marks toward lateral spots. Cruciform elevation dark ochraceous. Thoracic sternites ochraceous to brown. Legs brown to castaneous partly with darker areas. Fore femur with small subapical spine as well as primary and secondary spines.
Wings hyaline. Fore wing venation castaneous to ochraceous basally and fuscous apically, without distinct infuscation. Coastal vein mostly castaneous. Basal cell weakly tinged with yellow. Basal membrane grayish. Hind wing jugum yellowish gray.
Operculum mostly ochraceous except fuscous or slightly darker inner and lateral margins; slightly oblique inward; much longer than wide; widest at apex; lateral length about twice the width at apex; not reaching posterior margin of sternite II. Two opercula not meeting medially.
Abdomen shorter than distance from head to cruciform elevation. Abdomen black with narrow reddish castaneous band along caudal margin of each tergites 3–7; with broad reddish castaneous band posteriorly on tergite 8; with a pair of lateral white marks on tergite 3, transverse white fascia along anterior margin of tergite 3, and sometimes indistinct transverse white fascia along anterior margin of tergite 7, all consisting of silvery hairs with white pollinosity. Timbal cover absent. Abdominal sternites castaneous with broad longitudinal median black fascia.
Male genitalia (Fig. 2 C, D): Pygofer ovate with long, triangular, acute dorsal beak. Upper lobe of pygofer triangular, acutely projecting toward uncus. Uncus separated into two leaf-like or roof-like lobes, longitudinally long and nearly straight in ventral view to surround aedeagus, with truncated apex in lateral view. Aedeagus with two spine-like processes, one very long and the other one short.
Description of female (Fig. 2 E, F). Operculum brown with narrow fuscous lateral margin and densely covered with silvery hairs; inner posterior corner pointed toward inner side; not reaching posterior margin of sternite II. Abdomen black with narrow reddish castaneous band along caudal margin of each tergites 2–7; with broad reddish castaneous band posteriorly on tergite 8. Abdominal sternites castaneous with broad longitudinal median black fascia. Abdominal segment 9 castaneous dorsally and laterally with a pair of longitudinal paramedian fuscous fascia and mostly fuscous ventrally. Gonapophysis IX (valvula 2) dark castaneous to fuscous. Ovipositor sheath fuscous, with its protruding part about twice the length of dorsal beak. Dorsal beak about twice the length of anal styles.
