Description: body; elongate-oblong, slender. Dorsal colouration metallic greenish-black, ventral colouration similar; femora glossy black, tibiae red.  Head unique to this genus; base of the head constricted into a neck; head very short, but rather broad; surface of the head mostly smooth; eyes very large, bulbous, strongly bulging laterally. Clypeus very small, located between the antennal bases (the base of the scapus is orange); labrum roughly the same size, with reddish front and lateral margins. Mandibles strongly curved, short; flattish, usually reddish in colour. Palpi pale. Antennae setose (lined with many very long setae, often used to hunt springtails); the scapus is considerably longer than any of the other antennal segments, glossy black in colour, with a greenish hue; pedicel reddish, very small, with a large frontal notch at the base; the second and third antennomeres following the pedicel are cylindrical, rough; all remaining antennomeres should look like normal carabid antennae, but are still setose, and the shorter antennal pubescence begins on the third segment following the pedicel. Pronotum ovate, flattish. Front angles obtuse-rounded; lateral margins strongly rounded; hind angles obtuse; basal margin usually straight. Lateral margins beaded, with one marginal seta just above each hind margin. Median line thin; the pronotal disk on either side of the median should be elevated, smooth, glossy greenish-black. The basal dorsal margin should be heavily punctate; one slender, elongated dimple may be found on either side of the lower median. Scutellum small, exposed. 12 well-defined, pitted striae per elytron, intervals flattish. The 4th elytral interval should possess three well-spaced pits. Humeral shoulders round, apices round, somewhat pointed.

Males and females within the genus Loricera can be told apart by the width of the protarsi.
