(For extensive synonymy list, see Jansson 1995 .) Diagnosis Body length 3.6–4.4; only macropterous form known. Pronotum distinctly longer than median head length. Hemelytron ( Fig. 1A ): corium with three longitudinal brown stripes, sometimes in broken pattern or indistinct; embolium with a set of four short brown stripes, sometimes confluent into a long unbroken stripe. Males: fore femur with three spines on proximal third ventrally, one spine on middle third and three spines on distal margin; fore tibia with two spines on distal third; palar claw slender, slightly sinuate ( Fig. 2A ). Free lobe sub-rectangular, posterior margin concave, lateral angle produced, with ca 30 long setae ( Fig. 2B ). Left paramere: shaft stout, tapering distally, apical part slightly bent and twisted ( Fig. 2D ). Right paramere: shaft bent and slightly enlarged at distal third, then tapering towards narrowly rounded apex; basal lobe sub-rectangular ( Fig. 2C ).

Other countries: from Africa through Arabia, Palestine , southern Asia to Southeast Asia and southern China ( Wróblewski 1968 ; Nieser 2002b ; Zettel et al. 2017 ). Remarks This is the largest species of Micronecta occurring in Vietnam . It has some similarities with M. sedula Horváth, 1905 and M. siva (Kirkaldy, 1897) in the structures of the male genitalia, but can easily be recognised by its larger body (also see Remarks under M. siva ).
