Paratypes: Coleccion de Practicas Zoologicas Universidad del Valle, Cali, Colombia (CPZ-UV 5304), adult, sex undetermined, collected near the town Cerrito, Valle del Cauca, Colombia, by WB-G in the morning of September 28, 2017 (3.68483, 76.31340, 990 MASL) [armandoi]
|Diagnosis||Diagnosis: Liotyphlops bondensis can be distinguished from other Liotyphlops by the following combination of characters: (a) eyes always visible due to a transparent ocular scale (Figures 1–3); (b) narrow preocular scale (third scale from the first vertical row) with a marked square angle (Figures 2–4); (c) pre-subocular scale blocks the contact between the third supralabial and the ocular scales; (d) third supralabial scale taller than the rest, reaching the posterior margin of the third scale from the first vertical row (Figures 2–4 and Tables 1 and 2); (e) superior preocular scale about 1⁄2 the width of the ocular scale (Figures 2–4); (f) posterior edges of the pre- frontals not extending beyond the posterior edge of the rostral (as indicated in Santos, 2018 for L. albirostris); (g) large frontal scale wider than longer; and (h) posterior edge of the scales of the first vertical row even (i.e., all with the same posterior extent, Figure 4) (Linares-Vargas et al. 2021).|
Diagnosis (bondensis): In addition to the characters mentioned above for L. bondensis, members of Liotyphlops b. bondensis can be distinguished by having: (a) rostral scale circular and (b) frontal scale width three times its length (Figure 2a–c) (Linares-Vargas et al. 2021).
Diagnosis (armandoi): In addition to the characters mentioned for L. bondensis, members of Liotyphlops b. armandoi can be distinguished by having: (a) rostral scale spatulated, or rectangular with a rounded end and (b) frontal scale width four times its length (Figures 2 and 4) (Linares-Vargas et al. 2021).
|Comment||Synonymy. L. bondensis was considered a synonym of L. albirostris for most of its history but resurrected by Linares-Vargas et al. 2021.|
Distribution: see map in Linares-Vargas et al. 2021. The species distribution models also project the possible presence in Venezuela, in areas surrounding Lago de Maracaibo in the Estados of Zulia, Trujillo, Mérida (especially along the Mérida Mountain range) and Falcon.
|Etymology||armandoi: The subspecific epithet is named after our friend Armando Carabalí Vanin, who died while hiking the Puracé volcano in the year 2000. We (AH-M, WB-G, DOD, JDD), who had the opportunity to interact with Armando during his short life will always remember him for his unconditional friendship during our years as undergraduate students at Universidad del Valle. Armando is survived by his mother Oliva Vanin.|
