Description.

Female body length: 0.98-1.31 mm (n=9). Male body length: 1.11 mm (n=1). Male antenna: apically clubbed. Number of antennomeres in male club: 3. Number of female clavomeres: 4. Setation of frons anterior to ocellar triangle: present. Setation of vertex posterior to lateral ocellus: dense. Hyperoccipital carina: absent. Pronotum in dorsal view: large, collarlike. Dorsoventral band of dense setation on posterior part of lateral pronotum: absent. Setation of pronotal cervical sulcus: sparse to absent. Width of dorsal mesopleuron in lateral view: half as wide dorsally. Longitudinal striation on dorsal mesopleuron: absent. Transepisternal line: present. Mesofurcal pit: uncertain, present. Notaulus: absent. Wings: brachypterous. Color of legs: yellowish brown. Foamy structures of lateral propodeum: smaller than hairy metapleuron. Median tubercule on T2: present. Setation of anterior T2: interrupted medially. Lateral patch on T2: absent. Foamy structures on S1: absent. Transverse felt field on anterior S2: present as transverse strip. Shape of S2 in lateral view: broadly convex.

Diagnosis.

Helava microptera and H. reducta are the only species without fully developed wings. They are easily separable by the presence of ocelli, a transepisternal line, and a scutoscutellar sulcus in H. microptera , all of which are absent in H. reducta .

Etymology.

The Greek name " Helava microptera " refers to the small size of the wings in males and females of this species.
