Figures 9-13

Description.

Female body length: 0.89-1.33 mm (n=20). Male body length: 0.99-1.33 mm (n=20). Male antenna: filiform. Number of female clavomeres: 3. Setation of frons anterior to ocellar triangle: absent or sparsely present only along inner orbit of eye. Setation of vertex posterior to lateral ocellus: dense. Hyperoccipital carina: continuous across vertex. Pronotum in dorsal view: present mostly as lateral shoulders. Dorsoventral band of dense setation on posterior part of lateral pronotum: present. Setation of pronotal cervical sulcus: dense. Width of dorsal mesopleuron in lateral view: about equal ventrally and dorsally to 1.5 times as wide ventrally. Longitudinal striation on dorsal mesopleuron: absent. Transepisternal line: present. Mesofurcal pit: present. Notaulus: percurrent. Rs+M in fore wing: nebulous. Wings: macropterous. Rs+M in hind wing: nebulous Color of legs: bright orange yellow. Setation of coxae: dense Foamy structures of lateral propodeum: larger than hairy metapleuron. Median tubercule on T2: present. Setation of anterior T2: interrupted medially. Lateral patch on T2: absent. Foamy structures on S1: present at lateral margin of sternite. Transverse felt field on anterior S2: present. Shape of S2 in lateral view: broadly convex.

Diagnosis.

Helava allomera can be differentiated from other species in the genus by the combination of the well-developed hyperoccipital carina, percurrent notauli, and foamy structures on the propodeum that are larger than the visible part of the metapleuron in lateral view. Within Helava , this is the only species with a dorsoventral band of dense setae along the posterior margin of the lateral pronotum (Figure 9 ).

Etymology.

The epithet " Helava allomera " is given to this species in reference to the unusual form and segmentation of antennae in both sexes.
