Non-type material. Zelurus abalosi Lent & Wygodzinsky, 1951 . 1 male [ CTIOC, 13182], Bolivia, Santa Barbara , Nor Yungas, XII / 1997, Sanchez, P. leg., Gil-Santana det., 2021.

Since Zelurus montivagus , the species which shows more morphological similarities with Zelurus galvaoi sp. nov., was considered by Lent and Wygodzinsky (1955) as proximate to Z. abalosi , the latter was included in this study for a more thorough comparison. Zelurus abalosi was described based on 12 type specimens (9 males and 3 females) from Argentina ( Lent and Wygodzinsky 1951), without further records so far ( Maldonado 1990). Photographs of a male paratype deposited in CTIOC are presented here ( Figs. 1-4 ).

In their description, Lent and Wygodzinsky (1955) presented only schematic drawings of some portions of Z. abalosi . Therefore, the first photographs of the species are presented here ( Figs. 1-3, 5 ). Additionally, Z. abalosi is recorded from Bolivia for the first time, based on a male specimen from this country ( Fig. 5 ).

Comments. The paratype and the male from Bolivia ( Figs. 1-3, 5 ) agree well with the original description ( Lent and Wygodzinsky 1951). Lent and Wygodzinsky (1955) briefly stated that the differences between Z. abalosi and Z. montivagus were the following: interocular distance, size of eyes, apical process of scutellum longer in relation to those of pronotum, absence of abdominal denticle and coloration of hemelytra.

In relation to each species, these differences are: 1 - interocular distance smaller ( Z. abalosi ) or somewhat larger ( Z. montivagus ) than the width of an eye; 2 – eyes larger in Z. abalosi ; 3 – processes of pronotum smaller in Z. montivagus and therefore smaller in relation to the process of scutellum; 4 – spiniform process on apicolateral angle of first connexival segment present ( Z. abalosi ) or absent ( Z. montivagus ); 5 – corium of hemelytra darkened with the basolateral portion pale and a subapical large yellow rounded spot in Z. abalosi ( Figs. 1, 5 ) and pale orange to pale yellowish with basolateral portion (in less extent), inner portion of corium, and apices brownish in Z. montivagus ( Figs. 37 , 42 ).

Distribution. Argentina, Bolivia (new record).
