Dindymus (Dindymus) baliensis sp. nov.

( Figs. 29, 32)

Type material. HOLOTYPE: J, INDONESIA: BALI: Badinkau , 300-500 m a.s.l., 10.-14.xi.1991, I. Löbl lgt.( MHNG). Antennae and left middle and hind leg of the holotype missing.

Description. Colouration ( Fig. 29). Body dorsally mostly pale red. Scutellum black with only apex red. Membrane grey, translucent, with median rounded black spot near level of half-length of posterior corial margin, but not reaching it. Red colouration on ventral suface of head, pronotal epipleuron, pleuron I and posterior pleural flange I in dorsal half, and ventrites (except of large lateral spot). Black colouration on legs, entire labium, pleura II and III and large lateral spot on ventrites reaching nearly posterior margin of ventrite VI. Posterior pleural flange II dark, somewhat lightened; posterior pleural flange III and epicoxal lobe III whitish.

Structure. Body slender. Head somewhat elongated in front of eyes, frons narrower, eyes less gibbous; lower margin of head only slightly rounded in lateral view. Pronotum narrower; callar lobe only slightly gibbous; lateral pronotal margins rather narrow, near level of callar lobe base slightly concave, narrowing towards pronotal base, not gibbous sideways; pronotal lobe rather flat. Profemora ventrally on apices with one small denticle. Labium reaching base of ventrite III.

Pygophore ( Fig. 32). Ventral rim posteriorly gibbous in lateral view; in frontal view detached from ventral wall by distinct furrow, regularly widely incised, with one prominent tooth on both ends of the incision. Ventral rim infolding nearly horizontal, medially with high longitudinal ridge, its upper edge sharp, narrowly black. Divided parts of ventral rim infolding dish-shaped, parameres placed near the end of ridge. Parameres medially nearly flat, this part directed forward and sideways; apically projected into acicular, rather long and thin processus hamatus directed medially, in apical part rounded and pointing even more medially. Parameres touching but not crossing each other. Dish-like depression on ventral rim infolding laterally emarginated by high, widely rounded ridge extended towards middle of pygophore; with slightly dish-like lateral rim infolding behind it. Anal tube wide.

Punctation on pronotal lobe, scutellum, clavus, and corium very fine, less dispersed on pronotal lobe than on other parts.

Measurements (all in mm). Male (holotype). Body length 9.94; head: length 1.78; width (including eyes) 1.67, interocular width 1.00; pronotum: total length 1.89, width 2.86; scutellum: length 1.13, width 1.29; corium: length 4.86, width 1.73.

Differential diagnosis. Dindymus (D.) baliensis sp. nov. ( Fig. 29) is unique within the nominotypical subgenus Dindymus Stål, 1861 , by the parameres, whose apices are only touching but not crossing each other, which is possibly caused by the presence of a sharp median ridge ( Fig. 32), also unique within all known Dindymus species. Dindymus (D.) rubiginosus (Fabricius, 1787) further differs from D. (D.) baliensis sp. nov. in the following characters: pronotal base with pale margin; scutellum red; small black spot on the membrane base and an oval black spot between apices of corium, which is touching these apices (in some rare cases extended nearly towards the apical margin of the membrane which is only narrowly rimmed with grey); labial segment I red except apex; all posterior pleural flanges and epicoxal lobes creamy, pleuron I (except of dorsal margin) red; large black lateral spot on ventrites reaching only posterior margin of ventrite V; ventral rim of pygophore with two large teeth and laterally sometimes with one small denticle; ventral rim without high median ridge; aciculate processi hamati of both parameres crossed ( Fig. 33).

Etymology. Patronymic, named after the Bali Island.

Distribution. Indonesia, Bali.
