Remarks. Giordani Soika (1960) and van der Vecht (1963) respectively compared L. vandervechti with L. amoenus and L. spiniger de Saussure 1867 distributed in Java. The differences between these species and L. rufomaculatus are given in Table 1 .

FEMALE. Head in frontal view nearly circular; frontal foveae circular, deep but not well defined (deep and distinctly defined in L. spiniger ); pronotal spines long, sharp (Fig. 69); metasomal segment 1 relatively stout, in lateral view evenly convex dorsally in posterior half (Fig. 65) (relatively long and slender, in lateral view clavate, swollen dorsally near posterior end in L. amoenus (Fig. 66) and L. rufomaculatus ).

MALE. Clypeus (Fig. 68) more narrowed dorsally, dorsal margin more emarginate medially than in female (Fig. 67).

The female specimen from Lombok slightly differs from Sumbawa and Flores ones by lacking yellow spot on mesepisternum; by black median part of tegula; by lacking apical yellow spot on fore femur.

Distribution. Indonesia: * Lombok, Sumbawa, Flores.
