Atractus marthae Meneses-Pelayo & Passos, 2019

Materials examined. COLOMBIA • 1 adult ♂; Santan- der, municipality of Sucre, La Pradera, Fontibón ; 05° 51ʹ53″N, 073°54ʹ37″, 2574 m a.s.l.; 03 Feb. 2018; María Estupiñan leg.; UPTC­R 0594 • 3 adults ♀; Santander, municipality of Sucre, La Pradera, Colegio ; 05°52ʹ05″N, 073°54ʹ15″W, 2574 m a.s.l.; 23 Jun. 2017; Juan Carva- jal leg.; UPTC-R 0591 to UPTC-R 0592 , UPTC-R 0602 .

Identification. Atractus marthae was identified by: dor- sal scale rows 17/17/17, smooth; postoculars two, loreal long, temporals 1 or 2; and hemipenis moderately bilobed, with lobe size equivalent to the capitulum length, semicapitated and semicalyculated ( Meneses-Pelayo and Passos 2019).

Remarks. This species occurred in the grassland habitat, where it was found under rocks ( Fig. 9D ). No individuals were detected in other habitats ( Fig. 2C ), which would make their detection difficult. We observed much variation in color intrapopulation, with the ground color blackish ( Fig. 9A, B ) to reddish with dark longitudinal lines ( Fig. 9C ). In February 2018, we observed eggs and hatchlings under a fallen tree trunk, which is the first ob- servation of reproduction for this species.
