Description.

Female body length: 0.94-1.24 mm (n=12). 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: present mostly as lateral shoulders. 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: about equal ventrally and dorsally to 1.5 times as wide ventrally. Longitudinal striation on dorsal mesopleuron: present. Transepisternal line: present. Mesofurcal pit: present. Notaulus: absent. Rs+M in fore wing: absent. Wings: macropterous. Rs+M in hind wing: absent. Color of legs: yellow; 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 simplex is the only macropterous species in the genus without a pigmented basal vein in the fore wing (Figure 60 ).

Etymology.

The epithet " Helava simplex " is given to this species in reference to the absence of several character states (notaulus, foamy structures).
