Zelurus singularis Lent & Wygodzinsky, 1947

( Figs. 45-48 )

Zelurus singularis was described based on four males from Argentina. The species presents a conspicuous elevated pair of large prominences on the posterior lobe of pronotum, what was considered very characteristic by Lent and Wygodzinsky (1947), since it had never been recorded to other species of Zelurus so far. Probably because of that Lent and Wygodzinsky (1947) did not compare the species with any other, besides naming it as they did.

Considering some characteristics of Zelurus singularis , such as the corium of hemelytra mostly pale, orange ( Fig. 45 ), similar to those of Z. galvaoi sp. nov. ( Figs. 6-7 , 30-31) and Z. montivagus ( Figs. 37 , 42 ), the species was also included in this study.

Type material. Zelurus singularis Lent & Wygodzinsky, 1947 [ CTIOC]. Holotype male: [bordered label:] [handwritten:] Zelurus singularis / n. sp. 10/946 / Wygod. & [printed:] H. LENT DET. // [bordered label:] [printed:] N. [handwritten:] 599 / [printed:] HEMIPTERA / [printed:] Inst. Oswaldo Cruz // [bordered printed label:] CTIOC / N°. 3174 // [written on typewriter:] Bosq // [handwritten:] San Juan // [handwritten:] fotografado [photographed] // [printed red bordered label:] HOLÓTIPO [holotype].

Comments. Zelurus singularis has a general similarity with the species studied here such as the dense and long setosity of the body, particularly on the legs; the general coloration, including corium mostly pale orange with dark portions on basal, medial and distal portions; pale legs; and fore and middle femora and tibiae with a similar armature as recorded in the other species ( Lent and Wygodzinsky 1951, 1955; this work) ( Figs. 45- 47 ). On the other hand, apart from the conspicuous large prominences on posterior lobe of pronotum, unique in the genus, the longer process of scutellum ( Fig. 47 ) is prone to separate Z. singularis from the other species studied here.
