Small dark lake-like craters and low-albedo regions, lettered by the IAU
(this list needs to be updated).
- Drebbel E (part of the semi-circle shaped formation of dark spots southwest of Mare Humorum) (seems to have been called Nobelarii by Langrenus).
- Fourier A (very near the "centre" of the semi-circle shaped formation of dark spots southwest of Mare Humorum).

- Lacroix R (west of Harold Hill's Basaltic Lava Areas south-southwest of Vieta).
- Lehmann E (part of the semi-circle shaped formation of dark spots southwest of Mare Humorum).
- Lepaute E (in the Dark V feature south of Mare Humorum).
- Mees Y (immediately north of Mees itself)(see LAC 54 and LAC 72 in the Clementine Atlas of the Moon)(pages 108 and 144).
- Rocca A (immediately east of Rocca itself)(see LAC 73 and LAC 74 in the Clementine Atlas of the Moon)(pages 146 and 148).
- Schubert N (a typical dark lunar lake at 1.8° North/ 72.7° East, frequently photographed during the orbital mission of Apollo 10)(see also the lower left corner of LAC 63 in the Clementine Atlas of the Moon)(page 126).
Catalog of small dark lake-like regions, named or nicknamed by dedicated moon observers (not IAU-related)
(to get a good overview of the moon's low-albedo spots and craters, see the LROC ACT-REACT QUICK MAP, WAC MOSAIC - NO SHADOWS).
- Dark "V" (a nickname from D.Caes for the curious dark V-shaped area at 36°30' South/ 35° West)(between Lacus Excellentiae and Elger).
- Lacus Apollo 1 (an unofficial name from D.Caes for the rather large dark region in the triangle of craters Grissom, White, and Chaffee, at the southern part of farside basin Apollo).
- Lacus Apollo 8 (an unofficial name from D.Caes for the small dark region in the triangle of craters Lovell, Borman, and Anders at the southeastern part of farside basin Apollo).
- Lacus Bose (an unofficial name from D.Caes for the dark region immediately northeast of Bose, in which a curious system of wrinkle ridges is detectable; called Dorsa Bose).
- Lacus Daly (an unofficial name from D.Caes for the small dark area to the north-northeast of Daly).
- Lacus Laplace (an unofficial name from D.Caes for the "flat" region about halfway between Promontorium Laplace and Maupertuis).
- Lacus Risus Felis (the Smiling Cat, an unofficial name from C.A.Wood for the three dark regions between Mare Crisium and Mare Marginis) (and indeed, they look very much like a "smiling cat"!).
- Lacus Rook (an unofficial name from D.Caes for the dark region in the northern part of Mare Orientale's Montes Rook, in which a dark halo crater is located, at 10° South/ 96°30' West).
- Harold Hill's Basaltic Lava Areas (a couple of dark spots at 34° South/ 58° West, also called Honey Lake). These dark Basaltic Lava Areas were described and depicted by Harold Hill in his book A Portfolio of Lunar Drawings, pages 156 and 157.
- The dark streak across the floor of Hahn, which was probably called Mare Trans Hahn by J.H.Franz.
Nameless dark spots and regions on the moon's near side (not to be confused with dark-halo craterlets)
- The dark region at de Gasparis - Liebig - Palmieri, near Mare Humorum's southwestern rim (seems to have been called Arabiae paludes by Hevelius).
- The elongated dark region south of Piazzi B and several attached dark regions northwest, west, and southwest of Piazzi C
- The dark spot on the floor of Schluter, once called Mare Hiemis by Franz (Schluter is the crater once named Malvasia by Schroter).
- The tiny dark spot at 2°50' South/ 81°20' West, northeast of Schluter (see LAC 73 in the Clementine Atlas of the Moon).
- The dark spot immediately west of Fourier A (which is more-or-less the centre of the semi-circle shaped arc of dark spots southwest of Mare Humorum).
- The elongated dark spot south of De Gasparis A
- Several dark spots east of Lagrange Y
- The dark lake south of Vitello. It should be noted that, in this lake, near craterlet Vitello R, a small section of an officially unnamed lobate scarp was transformed into a short wrinkle ridge. It's interesting to try to locate the beginning (start) and end (finish) of this lobate scarp! I don't know if I'm the first one who noticed this remarkable feature (?). I would like to know if there's a map of this region, with the pinpoint locations of the entire scarp. - DannyCaes DannyCaes Dec 17, 2015
- The two dark craters near the northern eye of the Smiling Cat (Lacus Risus Felis).
- The dark dish shaped crater northwest of Bartels A.

- The dark spot southwest of Golitsyn
- Several dark spots south-southeast of Levi Civita F
- The dark region in the (rather pronounced) unnamed crater about halfway between Voskresenskiy and Struve H (this pronounced crater seems to be nameless on the LROC Act-React Quick Map, and it has also no name or letter designation on LAC 37 in the Clementine Atlas of the Moon) (strange).
