Type material (1).

Holotype: COSTA RICA: Alajuela; Est. Biol. Alberto Brenes; nr. San Ramon; 29 JUN 1999, 900m; MA Ivie. Malaise ( USNM).

Etymology.

The species was named after VSF’s friend, Felipe Francisco Barbosa, a.k.a. Cidão, for his priceless advice and discussions on beetle taxonomy and systematics.

Diagnosis.

The weak black discal macula that does not reach any margin is unique in this species, as most other species with bicolored pronota have the strong discal macula reaching the hind margin. The exception is L. opaca  , which has a strongly demarcated discal macula. They are further distinguished by a black antennomere XI (white in L. cidaoi  ). The unique male genitalia have a stout median lobe which is 1.3 × longer than parameres and a rounded apex (Figure 32).

Description.

General dorsal coloration dark brown, pronotum and antennomere XI yellow, pronotum bearing weak discal black macula (Figure 7). Antennae subserrate; antennomeres IV–IX dorsoventrally flattened (Figure 16); scape subconical, antennomeres II and III short, subequal in length, approx. 1/4 length of I; antennomere IV elongate, approx. 1/3 longer than I; antennomeres V–IX gradually decreasing in length. Mandibles elongate. Labrum wider than long. Maxillary palpomere I short, approx. 1/3 length of II, which is cylindrical, palpomere III approx. half length of II, IV elongate, subequal in length of II, acuminated, densely setose. Labial palp 3-segmented, palpomere I and II subequal in length, palpomere III elongate and cylindrical, acuminated, densely setose.

Pronotum trapezoidal, not constricted medially, with posterior margin straight, anterolateral angles rounded, with posterolateral angles and pronounced and acute, divergent, with weakly visible longitudinal carina in anterior portion of pronotum, bifurcate posteriorly forming an areola, hardly visible. Prosternum V-shaped; posterior margin rounded; laterally reaching hypomeron.

Elytra approx. 11 × longer than pronotum, slightly expanded in 2/3 portion; costae I, II and IV strongly visible. Humeral region rounded, non-pronounced (Figure 7). Legs slender, elongate. Pro- and mesocoxae bearing stemmata. Aedeagus with median lobe stout, apex rounded, 1.3 × longer than parameres; parameres 1.3 × length of phallobase; phallobase elongate with posterior margin rounded (Figure 32).

Length (pronotum+elytra): 4.5 mm. Width (across humeri): 1.1 mm.
