MALE. Description: Head, mesosoma and metasoma dark castaneous; antenna, mandible, palpi, legs, tegula, wing veins, anterior and median legs castaneous; wings hyaline and ocelli translucent.
Head: Inconspicuously punctate (Fig. 53). Mandible with two apical teeth. Eye large, elliptical, HE 1.75 x WE (Fig. 54). Malar space strigulate (Fig. 53). Face above of clypeus with reduced protuberance (Fig. 54). Gena bulging in frontal view, wide in lateral view, WG 1.50 x WTO, genal carina incomplete or interrupted (Fig. 54). Lateral of vertex evenly convex in frontal view (Fig. 53). Ocellus large, DAO 1.00 x WTO; ocellar triangle not raised in frontal view (Fig. 53). Anterior ocellus not aligned in dorsal view of head. Clypeus wide (Fig. 53). Occipital area narrow (Fig. 54). Subocullar groove with inconspicuous carina (Fig. 53). Toruli polished around them (Fig. 54). Antenna inserted at reaching level of eye top (Fig. 53). Antennal segments evenly wide; pubescence subappressed, without some setae outstanding; scape short, scape LS 0.81 x HE; flagellomere I long, LF 1.83 x LP (Fig. 58).

Mesoscutum linear, lateral carina incomplete anteriorly; notaulus sulcate, arched (Fig. 55). Lateral scutellar region umbilicated; posterior region of scutellum gibbous in profile (Fig. 59). Median region of scutellar groove with small fovea. Metanotum conspicuous medially. Propodeum shallowly areolate; median region of dorsal propodeum polished; posterior region flat in profile; small ridge posterolaterad of insertion of petiole absent (Fig. 59). Mesepimeron weakly scrobiculate. Mesepisternum wide; anterior region partially areolate; posterior margin irregularly areolate; upper region evenly areolate; lower region polished, anterior area of lower region with fovea evenly sparse; central region weakly concave (Fig. 60). Metapleuron areolate-umbilicate; metepimeron almost flattened. Distal region of metafemur not dilated. Tarsal claw with two teeth. Basitarsal projection of hind leg long, with blunt apex. Wing LFW 3.20 x LM. Basal cell setose.

Comments. Decevania hemisphaerica sp. nov. differs from the others species by having head with inconspicuous punctate; eye elliptical; torulus inserted at top height eye level; gena dilated frontally, wide lateraly and genal carina incomplete; subocular groove with inconspicuous carina; flagellomere I long; M+CU, 1CUa, 1CUb and 2CU very sinuous and petiole strigate dorsally.
Distribution. Bolivia.
Etymology. The name refers to the globose shape of head in profile.
