Diagnosis. The species can be differentiated by the body coloration, with elytra yellow, and elytral suture light brown at basal ¼, that is similar to the following species but having smaller eyes, maxillary palpomere 2 twice longer than palpomere 3, and branch of the third antennomere 1.5× longer than antennomere. The main diagnostic character is the shape of male genitalia with phallus constricted at distal 2/3 and parameres with apical and subapical hooks.

Redescription. Pronotum yellow with centered dark brown spot. Elytra yellow, elytral suture light brown at basal ¼ (Fig. 16). Trochanters light brown, femur dark brown with basal 1/3 light brown. Tibiae dark brown.

Eyes medium-sized, eye diameter 1.3× longer interocular distance. Antennomere 4 as long as 5, 1.5× longer than 3. Branch of antennomere 3 1.5× longer than antennomere. Mandibles hooked. Labial palpi short, terminal palpomere rounded apically. Maxillary palpi elongate, palpomere 2 twice longer than palpomere 3 and 1.3× longer than 4, palpomere 4 distally rounded. Pronotum 1.1× wider than long medially, anterior angles slightly projected forward (Fig. 3). Elytra 3.8× longer than humeral width. Trochanters as long as quarter of femur length. Phallus constricted at distal 1/3, broad medially as wide as phallobase in ventral view, forming phallic folding projected ventrally in lateral view. Phallus distally narrow and pointed. Parameres with apical and subapical hook-like projections. Phallobase as long as half of phallus (Figs. 6–7). Body length: 5.5 – 6.2 mm, humeral width: 1.2 – 1.4 mm.

Distribution: Panama.

Comments: The syntype series on which the species was based includes members of 2 species. Therefore, according to ICZN (1999, Art. 74.1, 74.7) the lectotype (male) is here designated to become the name-bearing type of Calocladon chiriquense Gorham, 1884 . Simultaneously, 3 paralectotypes (2 males, 1 female) are designated, while remaining syntypes belong to a new genus a description of which is in preparation.
