Material examined.

CAMBODIA (all coll. RBINS): 4 males, Siem Reap prov., Angkhor, Preah Khan Temple, 24 January– 21 February 2006, Malaise trap in secondary forest (leg. Oul Yothin); 1 male, Siem Reap prov., Angkhor, Preah Khan Temple, 12 May 2006, sweep netting (leg. Oul Yothin).

THAILAND: 1 male (coll. RBINS); Loei prov., Na Haeo Field Research Station (17°29'27.1"N, 101°03'34.6"E), 769 m, 16 May 2003, sweep netting along stream and water fall in secondary forest (leg. P Grootaert).

Diagnosis.

Costa swollen before and at the level where R1 joins the costa (Figure 4). Wing clear. Hind coxa yellow. Tip of phallus ventrally with a number of denticles. Hypandrium unarmed. Cercus (Figure 5) with weakly digitated margin. Marginal bristles on cercus brown. Apical marginal bristle longest, blunt-tipped inserted on a long tubercle; subsequent two marginals flattened and blunt-tipped, subsequent bristles with simple tip; 6th bristle fine, pale; subsequent bristles long, brown. A long blunt-tipped interior, longer than the apical marginal.

Description.

We refer to the detailed description of L. dentalis in Zhang et al. 2009.

Comments.

The specimens from northern Thailand and central Cambodia correspond entirely to the description and figures given by Zhang et al. (2009). Especially the widening of the costa where the R1 joins the costa as is drawn by Zhang et al. (2009) but not mentioned in the description. The new records are not unlikely since the locality in the Loei province (Thailand) and the one in Cambodia are not so far from the southern Yunnan province (China) that is the type locality of this species.

L. dentalis is very closely related to L. semakau sp. n. from Singapore and we refer to the comments under the latter species.

Distribution.

China, Cambodia, Thailand.
