Diagnosis

Body length 2.4–3.3. Pronotum slightly shorter than median head length. Dorsum generally greyish. Pronotum with a transverse brown stripe, sometimes broken in the middle. Hemelytron with numerous dark brown spots; embolium with three dark spots.

Males: Fore femur, palar claw ( Fig. 20A ), median lobe of sternite VII, and free lobe ( Fig. 20B ) as in diagnosis of subgenus. Fore tibia with two spines ventrodistally. Left paramere: shaft stout, with knoblike apex; basal lobe tongue-shaped, directed towards apex of paramere ( Fig. 20D ). Right paramere: shaft relatively slender, curved at distal third, slightly widened, then tapering towards a narrowly rounded apex ( Fig. 20C ).

Distribution

Vietnam: Hanoi, Quang Ninh, Ha Tinh ( Wróblewski 1962, 1967, as M. punctata ); first records for Ninh Binh and southern provinces of Vietnam. Other countries: widespread from India and Sri Lanka through Southeast Asian mainland to Sumatra, Java, and Bali ( Nieser 2002b).

Remarks

Micronecta haliploides can immediately be recognised by the distinct dark spots scattered on the hemelytra. In this species the knob-like apex of the left paramere is also unique within Micronecta .
