Scutellar groove narrow, fused with axilla, arched, not dilated at ends; scutoscutellar sulcus inconspicuous; scutellum long, coriaceous, plane, not touching propodeal disc; axilla polished, deep. Metanotum overlapping lateral region of scutellum. Propodeal disc as long as half width, with central fovea fused with propodeal triangle fovea; median carina incomplete; without longitudinal ridge between median and inner discal carinae; spiracle elliptical; inner discal carina complete; sublateral carina absent; lateral carina present; lateral margin sculpture followed by short striae; posterior carina complete; posterior spine of propodeum absent.

Legs. Metacoxa with dorsal spine, with ventral expansion. Protibia short [1.5× first tarsomere length], with protibial spur short [shorter than half length of first tarsomere]. Tarsi with tarsomeres 1–4 progressively shorter distad, cylindrical; tarsal claw with two sharpened teeth, curved posterad; arolium simple, apex straight, and large.

Metasoma. 1.86 × longer than wide; tergum 1 with ventral region coriaceous, with lap of lateral margin, without lateral pilosity; tergum 2 with dorsal region polished, without lateral pilosity, with ventral region polished; terga 3–6 with dorsal region polished, with ventral region polished; with posterior margin of tergites straight, with sparse setae at posterior margin of terga 2–6. Hypopygium ( Fig. 60 ) wider than long; with hypopygial median stalk undivided; lateral margin parallel, and slightly convex; with posterior margin bilobate with median indentation, concave, with lobate branch.

Genitalia ( Figs 75, 76 ). Genital ring protruding dorsally, with distal margin rounded and emarginated. Basivolsella fully outlined from basiparamere, with sparse line of hairs. Paramere fully divided into two arms; dorsal arm of paramere as long as ventral arm, club-shaped, and with basal margin thin; ventral arm of paramere wide at apex, apex sparse hairy, inner margin straight. Cuspis birramous, with arms slightly indistinct; ventral arm aligned with dorsal arm apex, slender, and thin, with apex rounded; dorsal arm wide, and with apex rounded. Aedeagus slender; with apex aligned with paramere apex, lobes touching each other, with apical margin rounded, lateral of margin of basal portion straight; apodeme parallel, with base straight.

Variations. Body length 2.0– 2.25 mm; fore wing length 1.28–1.71 mm. Head dark castaneous; scape light castaneous; pedicel light castaneous; mesosoma dark castaneous; fore coxa castaneous; hind coxa castaneous; fore tibia light castaneous; mid tibia castaneous; metasoma castaneous. Head with frons with weak carina. Propodeal disc with inner discal carina inconspicuous at ends.

FEMALE unknown.

Remarks. This species is similar to Clytrovorus exaggeratus Barbosa & Azevedo, 2011 by having the frons coriaceous; the ocellar triangle acute, compact with ocelli large; the antenna with first flagellomere as long as pedicel and other flagellomeres; the scutellar groove narrow and arched; the propodeal disc without longitudinal ridge between median and inner discal carina; the posterior spine of propodeum absent. However C. zafimaniry sp. nov. has the head longer than wide; the clypeal carina complete and arched in profile; the longitudinal pronotal furrow present; the propodeal disc with inner discal carina complete; the declivity of propodeum with median carina present; the mesopleural sulcus polished; the hypopygium without lateral projection anteriorly, whereas C. exaggeratus has the head wider than long, the clypeal carina incomplete and straight in profile; the longitudinal pronotal furrow absent; the propodeal disc with inner discal carina incomplete; the declivity of propodeum with median carina absent; the mesopleural sulcus foveolate; the hypopygium with lateral projection anteriorly.
