Type species. Hershkovitzia primitiva Guimar „es & D’Andretta, 1956, by monotypy.
Diagnosis. Head laterally compressed. Vertex membranous. Mesonotum hexagonal, thorax wider than long. Sternal plate with two sutures. Each pair of legs of different size and morphology. Female abdomen with six ventral plates and six dorsal plates, with tergites smaller than sternites. Male abdomen with six ventral plates and five dorsal plates, with tergites wider than sternites. Both syntergite 1+2 and sternite 1+2 present in male and female. Sternite 1+ 2 in both sexes with a ctenidium covering the entire posterior margin of the sternite or its middle third.
Redescription. Head covering part of mesonotum at rest. Funnel-shaped, with narrower base. Dorsal view: eyes with a single lens, present or absent; palps widening distally or not, with varying number of setae; vertex Vshaped and membranous. Lateral view: 0–6 genal setae; antenna with pedicel developed, straight and lined with small setae; flagellum straight and entirely lined with setae; arista dendriform; 0–5 postgenal setae. Ventral view: labella shorter than thecae.
Thorax dorsoventrally flattened, wider than long. Dorsal view: pleurae and mesonotum membranous; lateral plates absent; scutellum absent; mesonotum hexagonal; 2–4 notopleural setae; thoracic spiracle present; thoracic ctenidium composed of 10–14 spines, located between coxae I and II. Ventral view: sternal plate wider than long, with anterior margin arched and posterior margin straight; oblique suture right-, obtuse- or acute-angled; median sternal suture absent; two sutures on lateral margin of sternal plate; legs inserted on dorsal portion of body, each pair of different size and morphology: first pair inserted anterior to head insertion, second pair inserted posterior to thoracic ctenidium, third pair inserted anterior to halter.
Abdomen. Female. Dorsal view: syntergite 1+2 and tergites 3 to 7 sclerotized; arrangement and chaetotaxy of tergites varied. Lateral view: seven pairs of spiracles. Ventral view: sternites (1+2, 3 to 7) sclerotized; sternite 1+2 with a ctenidium of 30 to 58 spines on posterior margin; sternites wider than tergites; shape and chaetotaxy of sternites varied.
Male. Dorsal view: syntergite 1+2, tergites 3 to 6 and anal plate sclerotized. Ventral view: sternites (1+2, 3 to 5) sclerotized; sternite 1+2 with a ctenidium of 30 to 53 spines on posterior margin; tergites wider than sternites; format and chaetotaxy of tergites and sternites varied; anal segment conical, with associated setae.
