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.
