Iphita varians rubra subsp. nov.

( Fig. 10 View Figs ) Type material. HOLOTYPE: ♀ (brachypterous), INDONESIA: MENTAWAI ISLANDS: NIAS: Lawalo , 16.iii.1980, E. Diehl lgt. ( EHIA).

Description. Colouration ( Fig. 10 View Figs ). Body predominately black with red clypeus, anterior pronotal margin (slightly) and lateral pronotal margins (distinctly), anal vein and claval comissure, corium (except median spot), apices of femora (narrowly), and bases of tibiae. Black median spot on corium large, oval, indistinctly delimited, reaching inner corial margin and merging with blackish colouration of clavus.

Measurements (all in mm). Female (holotype, brachypterous). Body length 19.44; head: length 2.65, width (including eyes) 2.65, interocular width 1.62; lengths of antennomeres: 1 – 4.05, 2 – 4.27, 3 – 2.54, 4 – 3.83; pronotum: total length 3.83, pronotal collar length 0.86, callar lobe length 1.08, pronotal lobe length 1.89, width 5.29; scutellum: length 2.92, width 2.65; corium: length 9.94, width 3.35.

Differential diagnosis. The nominotypical subspecies, I. varians varians ( Fig. 9 View Figs ), differs in having the corium completely black with only the costal margins whitish yellow with an orange tinge.

Etymology. The subspecies epithet is the Latin adjective ruber (= red), referring to the colouration of the corium.

Distribution. Indonesia, Mentawai Islands, Nias. The nominotypical subspecies occurs in Sumatra ( BREDDIN 1909, BLÖTE 1931).

Note. The morphological characters of the examined brachypterous female from Nias fully correspond with brachypterous females of I. v. varians from Sumatra. It is interesting that some of the Sumatran populations of I. v. varians consist only of macropterous specimens, while others (e.g., a population from Soekaranda) are morphologically variable with common occurrence of brachypterous and cryptobrachypetrous specimens; this variability inspired BREDDIN (1909) to name this species as ‘varians’. Brachyptery and cryptobrachyptery are manifested in smaller-sized specimens, especially by a distinctly narrowed pronotum, lateral pronotal margins nearly straight and only hardly concave medially, shortened hemelytra and developed membrane that does not usually surpass the apex of abdomen.
