Podischnus cleidecostae sp. nov.

( Figs. 1E View Figure 1 ; 2E View Figure 2 ; 4B, D View Figure 4 ; 5E View Figure 5 ; 6E View Figure 6 ; 7E View Figure 7 ; 10 View Figure 10 )

Type material: HOLOTYPE ♂ ( DZUP), not dissected, labeled: “ BRASIL: Acre: Cruzeiro do Sul , IX.1956, R. L. GonÇalves ( DZUP)” . PARATYPES: 4 males with same data as the holotype (2 ♂ DZUP; 2 ♂, CERPE) .

Diagnosis: Podischnus cleidecostae sp. nov. is distinguished from other Podischnus species by the following combination of characters: cephalic horn in major males with broad, compressed apex, or with a small subapical tooth in lateral view ( Fig. 2E View Figure 2 ); prosternal process short, confined below the anterior coxae ( Fig. 4D View Figure 4 ); stridulatory apparatus separated by a medial row of setose punctures confined to the base of tergite VIII ( Fig. 5E View Figure 5 ); parameres laterally convergent on basal half ( Fig. 6E View Figure 6 ).

Holotype, male description

Body length: 45.26 mm.

Body width: 20.28 mm.

Color: Surface dark reddish brown.

Head: Clypeus subtrapezoidal in shape, bidentate at apex; teeth lobed, raised, separated by an emargina- tion in dorsal view; horn at the subapical clypeal area strong, curved backwards; horn apically compressed, expanded in lateral view, with a small, subapical tooth ( Fig. 2E View Figure 2 ); horn base setose at sides, glabrous medially. Frons weakly rugose near the eyes, smooth medially. Eye canthus glabrous,subtriangular in shape, slightly arched backwards. Antennae with 10 antennomeres; club subequal in length to antennomeres 2-7. Mandibles bidentate at apex. Mentum eliptical in shape, disc smooth, moderately covered by setose punctures on sides; apex widened.

Pronotum: Anterior angles strongly acute ( Fig. 4B View Figure 4 ); medial portion of discal area obtusely declivous in lateral view, with a weakly marked ridge extended to horn base in dorsal view; posterior area with a horn, project- ed backwards in lateral view, apically broad; horn apex finely punctate, strongly emarginated anteriorly, densely setose ventrally, at middle with a pit, extending posteriorly in a medial sulcus ( Fig. 1E View Figure 1 ). Lateral surface strongly rugopunctate at the midline.

Scutellum: Moderately punctate; punctures C-shaped, irregularly scattered.

Elytra: Surface almost completely covered by fine punctures; area above humerus with a row of six large, C-shaped punctures; lateral area bellow humerus with three incomplete rows of punctures; first and second rows extending until posterior area, punctures decreasing in size towards posterior area; third row with large punctures only.

Legs: Protibiae quadridentate. Mesotibiae with three medial and two distal teeth on external surface. Metatibia with four medial and three distal teeth on external surface.

Venter: Prosternal process short, triangular, confined below mesocoxae;central area with a small,setose tubercle.

Abdomen: Ventrite II with a complete medial row of transverse, setose punctures; ventrites III-V with rows confined to sides; ventrite VI covered by setae on posterior margin. Ventrites II-V rugose on sides, smooth on disc; ventrite VI rugose near anterior margin. Tergite VII with stridulatory apparatus formed by two parallel carinate bands; carinae well-marked and tubercle-like in shape near the base, gradually becoming finely marked and more transverse towards apex; basal area between carinae with a medial row of setose punctures, becoming irregularly scattered towards apex ( Fig. 5E View Figure 5 ). Tergite VIII strongly rugose on sides near apical margin; discal area weakly punctate; transversal area near basal margin moderately rugopunctate.

Paratypes, male variation

Differing from holotype in the following characteristics.

Body length: 44.99-37.27.

Body width: 19.77-16.92.

Head: Minor male with clypeal apex deeply emarginated; cephalic horn short, with no modifications; frons strongly punctate on sides.Cephalic horn in major males lacking apical expansion in lateral view, only with a small subapical tooth, or only with enlarged apex, with no subapical tooth.

Pronotum: Minor male with horn not as broad as in major males, tubercle-like shaped; dorsal horn surface with pit sometimes absent.
