Genus Mioscarta Breddin, 1901

Mioscarta Breddin, 1901: 123 (new genus), 183 (Zoogeography).

Type species

Mioscarta forcipata Breddin, 1901 .

Diagnosis

The genus can be identified by the following combination of characters:

Habitus general shape dorso-ventrally flattened, in lateral view total length nearly 4 times height ( Figs 2 , 4–11A ). Pronotum angle not more than 25° ( Figs 2 , 4–11A ). Distance between ocellus and compound eye 2 times ocellus diameter ( Fig. 1A ). Ocelli large, distance between eyes less than 8 times ocellus diameter ( Fig. 1A ). Apical reticulation of the tegmen generally developed and reduced in few cases ( Figs 4–11A–C ). Widest part of postclypeus in frontal view is at midheight ( Fig. 1A ). Apical curve of tegmen visible in dorsal view ( Figs 4–11C ). Widest part of habitus in dorsal view at midlength of tegmen ( Figs 4–11C ). Male subgenital plates is at least 1.5 times longer than pygofer height. Male subgenital plates appendage always present, longer than main plate ( Figs 5 , 7–8 , 10–11F ).

Among the Rhinaulacini , Mioscarta closely resembles Trigonoschema Crispolon & Soulier-Perkins gen. nov. with respect to the distance between ocelli, postclypeus shape in frontal view, postclypeus longitudinal groove, apical cells of the tegmen, Rp posterior wing, absence of r-m crossvein, and presence of sterno-lateral plate between subgenital plate and pygofer while Peociloterpa with respect to postclypeus longitudinal groove, absence of r-m crossvein, presence of sterno-lateral plate between subgenital plate and pygofer and paramere general shape, but they differ by the following characters presented in Table 2 below.

Distribution

India, Indonesia (Borneo, Flores and Sulawesi), Malaysia (Borneo), and Philippines.
