Type species.

Barinas flava González-Sponga, 1987, by original designation.

Emended diagnosis.

DS Epsilon type 1. Ocularium low, smooth, or with paired high spines ( Barinas piragua ). Mesotergal areas I-IV with paired paramedian spines (AHF: I <II = III = IV in B. flava , I = II <IV <III in B. piragua , II = I<III = IV in B. virginis comb. nov., and I = IV <II = III in B. guanenta sp. nov.). Posterior margin, free tergites, and anal operculum armed (with tubercles in B. flava , B. virginis comb. nov. and B. guanenta sp. nov.; with spines in B. piragua ). Pedipalps concolor with the body ( B. flava and B. virginis comb. nov.; lighter than the body in B. piragua and B. guanenta sp. nov.). Coxae I-IV with one anterolateral tubercle dorsally projected. Fe IV length/DSL ratio: less than three in B. virginis comb. nov (1.93) and B. flava (2.58); more than three in B. piragua (3.4) and B. guanenta sp. nov. (3.38). Lamina parva crescent-shaped (in B. flava seems heart-shaped) and with very short corners that do not exceed the insertion point of the MS-A2. Malleus with two pairs of trifid MS-A, one pair of trifid MS-B, two pairs of MS-D, one pair of large and trifid MS-E2, and one pair of MS-E1 (in B. piragua short an conical, in B. guanenta medium-sized and elongated; unknown in B. flava and B. virginis comb. nov.). Stylus elongated, curved dorsally at distal portion (straight in B. guanenta sp. nov.), smooth (in B. flava and B. virginis comb. nov.; with a dorsal hump close to the union of the DP with the stylus in B. piragua and B. guanenta sp. nov.), and with a sharp proximal DP (blunt in B. virginis comb. nov.).

Included species.

Barinas flava González-Sponga, 1987, Barinas guanenta sp. nov., Barinas piragua Ahumada-C. & García, 2020, Barinas virginis ( González-Sponga, 1987) comb. nov.

Remarks.

An emended diagnosis comparing Barinas with the remaining genera of Leiosteninae was offered by Ahumada-C. et al. ( 2020) and we decided not to repeat such information here. However, we want to emphasize that the presence of paired armature on mesotergal areas plus the basal DP of the stylus and the LP with very short corners not exceeding the insertion point of the MS-A2 are characters exclusive of Barinas .
