Diagnosis Body length 1.2–2.4. Pronotum about as long as median head length, slightly narrower than head width. Hemelytron ( Fig. 1F ) generally pale, with four indistinct, broken longitudinal brownish stripes. Males: fore femur with a row of seven spines in proximal and middle third; fore tibia with three spines distally; palar claw narrow, apical part slightly recurved. Median lobe of sternite VII with two long setae and a pointed apex. Free lobe sub-rectangular, posterior margin nearly straight, angles rounded, lateral angle with ca eight long setae ( Fig. 3D ). Left paramere: shaft styliform, apical part slightly constricted Fig. 3. Morphological features of species of Micronecta Kirkaldy, 1897 , ♂♂. A–C . M . decorata Lundblad, 1933 (ZVNU). D–F .
