Description of holotype.

Habitus narrowly elongate-oval, with slight discontinuity between pronotum and elytra (Fig. 5B); pronotum widest before base (Fig. 5B). Total length 2.0 mm; length without head 1.8 mm; maximum width 0.9 mm.

Color. Very dark brown to blackish dorsally and ventrally; lighter on anterior head, lateral pronotum, and bases of meso- and metatibia (Fig. 5B).

Surface sculpture. Head with a few setiferous punctures in front of a distinct occipital line; fine yet distinct microreticulation present on the entire head. Pronotum and elytron shiny, with moderately dense, coarse, setiferous punctation (Fig. 5B).

Structures. Head with distinct occipital line, with rounded clypeus. Antenna stout. Pronotum with distinct lateral bead and distinct, long, deep basal striae (Fig. 5B). Elytron with distinct, short basal striae.

Genitalia. Median lobe of aedeagus typical of the L. bogotensis complex, with slight variation in curvature among individuals in lateral view (Figs 8B, 10B); parameres simple, of the " Bidessini " type, 2-segmented.

Variation.

Measurements (N = 20). Total length 2.1-2.3 mm (mean 2.18); length without head 1.8-2.0 mm (mean 1.89); maximum width 0.9-1.0 mm (mean 0.96).

Occipital line in a few specimens interrupted, presence still evident.

Color. Usually darkly colored, but a few specimens with paler band-like markings on elytra.

Microreticulation on head sometimes hardly visible on anterior part or frons.

Metathoracic wings. Short, 2/3 of elytral length (in one dissected male paratype).

Female. Elytron with microreticulation on about the posterior 1/2 to 2/3.

Etymology.

Named after the type locality, Páramo del Almorzadero. The word “almorzadero” is a noun in the nominative singular standing in apposition.

Distribution.

Only known from the Páramo del Almorzadero (Fig. 1).

Habitat.

Exposed, shallow, densely vegetated, stagnant water bodies.
