Types	Holotype: lost, was ZSI 8028 (fide Vogel et al. 2020). Other material: MZMU
Diagnosis	Diagnosis: Pareas modestus differs from all other members of the genus Pareas by the combination of the following morphological characters: slender black body, small size (total length 226–357 mm); two anterior temporals, elongated; frontal scale is hexagonal with shield-shaped with the lateral sides converging posteriorly; anterior pair of chin shields is longer than broad; loreal not contacting the eye; prefrontal contacting the eye one subocular and one postocular; not enlarged median vertebral; 7–8 infralabial scales; 15 dorsal scale rows slightly keeled in 3–5 scale rows at midbody; 151–159 ventrals; 35–46 subcaudals, divided; body pattern uniform greyish black to black dorsum lacking cross-bands of bicolored spots and markings on the head; no collar; ventral surface uniform light greyish-white (Vogel et al. 2020: 562). Additional details (257 characters) are available for collaborators and contributors. Please contact us for details.
Comment	Behavior: nocturnal. Synonymy: See also Pareas macularius. Wall (1922) synonymized P. modestus (and P. andersonii) with P. macularius and most authors have followed this position, until Vogel et al. 2020 revalidated modestus. Distribution: see map in Vogel et al. 2020: 554 (Fig. 1).
