Description.

Female body length: 1.00-1.15 mm (n=19). Male body length: 0.94-1.12 mm (n=20). Male antenna: apically clubbed. Number of antennomeres in male club: 4. Number of female clavomeres: 4. Setation of frons anterior to ocellar triangle: absent or sparsely present only along inner orbit of eye. Setation of vertex posterior to lateral ocellus: very sparse or absent. 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: absent. Setation of pronotal cer vical 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: absent. Rs +M in fore wing: nebulous. Wings: macropterous. Rs+M in hind wing: nebulous. Color of legs: brownish. Foamy structures of lateral propodeum: larger than hairy metapleuron. Median tubercule on T2: absent. Setation of anterior T2: continuous across tergal midline. Lateral patch on T2: present. 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 carinata belongs to the cluster of species with large propodeal foamy structures that includes H. alticola , H. allomera , and H. samanthae . It can be separated from H. alticola and H. samanthae by the setation of the upper frons and posterior vertex, which is either absent or very sparse. In H. alticola the upper frons is glabrous or nearly so, and then abruptly setose posterior to the ocelli; the dorsal head in H. samanthae is setose throughout. Helava carinata can be separated from H. allomera by the absence of dense setation on the posterior part of the lateral pronotum (compare Figures 9 and 29 ).

Etymology.

The Latin adjectival epithet " Helava carinata " refers carinate vertex of the head.
