ARJUNINI SONG & SZWEDO TRIB. NOV.

Type genus

Arjuna Muir, 1934 .

Diagnosis

This new tribe can be distinguished by the following combination of characters: clypeus distinctly elongate, extending to apex of middle coxae; rostrum distinctly elongate, beyond apex of hind femora; tegmina submacropterous and transparent, apical one-third not overlapping, apex somewhat pointed; corium without fold; veins with long setae, Sc+R and M veins on tegmina with a long common stem; claval suture extending to posterior margin; hindwings with anal area reduced, only a very small portion folded inwards, secondary fold absent; ACL of gonapophysis VIII with seven large teeth of varying sizes and shapes from base to apex; basal four teeth with base transversally prolonged and strongly ridged; and Gp1 of gonoplacs with filmy edging, without sensory appendage.

Diversity and distribution

Arjunini includes eight species in two genera restrict- ed to the southern Sunda Islands and New Guinea only ( Fig. 25 ). This group may be distributed widely in Wallacea, New Guinea, and the western Pacific, which
