E t y m o l o g y: The holotype was collected near the Save-river, Mozambique.

R e c o g n i t i o n: The female of Cerceris saveensis is characterized in having the coxa III without longitudinal carina on coxa III, the apical margin of the clypeus is triangularly erected medially and the latero-clypeal area is emarginate ( Fig. 21a,b,c ), the mandible has a double tooth internally ( Fig. 21d ) and the mesopleuron has a tubercle. Additionally, the body is black, ferruginous and yellow colored, the wings are hyaline and behind the radial cell of forewings fuscous. The similar female of cratocephala differs from C. saveensis in having the wings fuscous with violaceous shine, the thorax and the legs are black, the scutum is longitudinally rugose with punctures between rugae and the gaster is ferruginous except petiolus. The female of C. chimoio is similar to C. saveensis but differs in having the apical of clypeus with five, teeth slightly erected and the body length is 9-10 mm ( C. saveensis has a body length of 11.5-12.5 mm).

The male of Cerceris saveensis is characterized in having the coxa II without longitudinal carina, the apical margin is ferruginous and tridentate ( Fig. 22a ), the flagellomeres IX-XI have tyloidea ( Fig. 22c ), the mandible has a rounded tooth internally, the sternum VI a nearly rectangular tooth apico-laterally and the genitalia are charcteristically shaped ( Fig. 22e ). The male of C. iniqua differs from C. saveensis by having the mandible with acute tooth internally, a broad clypeal brush and black and differently shaped genitalia.

D e s c r i p t i o n: ♀, 11.5-12.5 mm. Sculpture: apical margin of clypeus triangularly erected medially lateral with small tooth ( Fig. 21a,b,c ); latero-clypeal areas emarginate; mandible with double tooth internally, interantennal carina broad; prosternum without tranverse carina; mesopleuron with tubercle; epimeron without crest; propodeal enclosure obliquely rugose with distinct not crenulate medio-longitudinal furrow; petiolus wider than long, apico-medial with fossa; sternum II without basal plate; pygidial plate ( Fig. 21e ). Puncturation: clypeus micropunctate and finely punctate; frons micropunctate and punctate; vertex densely rugose-punctate; pronotal collar densely punctate; scutum with densely longitudinally elongate punctures; mesopleuron densely reticulate-punctate; scutum sparsely punctate; metanotum finely punctate; propodeal sides densely punctate; terga densely punctate; pygidial plate irregularly strulptured; sterna laterlally punctured. Pilosity: latero-clypeal areas covered with dense erect setae; rest of body covered with sparse setae. Coloration: black, following parts yellow: clypeus, frons, interantennal carina, mandible basal half, gena partly, pronotal collar, tegula anterior half, scutellum, metanotum, mesopleuron partly, epimeron, propodeal sides, petiolus lateral, terga II-IV partly, tergum V all and fore- and midlegs partly; following ferruginous: anterior margin of clypeus, flagellum (dorsally darkened), head partly, tegula partly, terga partly, pygidial plate, sterna predominantly, mandible apical half, fore- and midtibia partly, hindlegs; wings hyaline, apically fuscous.

♁, 11.5 mm. Sculpture: anterior margin of clypeus produced and tridentated ( Fig. 22a ); latero-clypeal areas emarginate; clypeus in lateral view nearly straight ( Fig. 22b ); mandible with rounded tooth internally; flagellomeres IX-XI with tyloidea ( Fig. 22c ); prosternum without transverse carina; propodeal enclosure obliquely rugose and medio-longitudinal furrow not crenulate; mesopleuron without tubercle; epimeron without crest; petiolus as long as wide; sternum VI with nearly rectangular tooth; pygidial plate ( Fig. 22d ), genitalia characteristically shaped ( Fig. 22e ). Puncturation: median part of clypeus shining and sparsely punctate; latero-clypeal area and frons micropunctate and punctate; vertex densely punctate; prosternum sparsely punctate; pronotal collar densely punctate; scutum and scutellum densely rugose-punctate; metanotum punctate; propodeal sides densely rugose-punctate; terga densely coarsely punctate; pygidial plate punctate. Pilosity: latero-clypeal areas covered with dense erect setae; clypeal brush small ( Fig. 22a ); rest of body covered with sparse erect setae. Coloration: black, following parts yellow: clypeus, frons, mandible basal half, spots behind ocelli, gena partly pronotal collar, mesopleuron partly, epimeron, tegula partly, scutellum, metanotum, propodeal sides, terga II-V apico-lateral (variably), tergum VI, sterna III-V apico-lateral, legs partly; following ferruginous: apical margin of clypeus, petiolus, tergum II partly, pygidial area, flagellum (dorsal fuscous), sterna predominantly, legs partly; wings hyaline, apical fuscous.

D i s t r i b u t i o n: Mozambique.
