The stout antennae and rounded anterior margin of the pronotum are unique to this species (Figure 1). The strong pronotal macula that does not reach the base of the pronotum is also diagnostic. The scaliform setae on antennomeres IV-XI are likewise unique in the genus (Figure 18). The male genitalia (Figure 34) can be used to confirm the identification. Redescription. General dorsal coloration dark brown, pronotum and antennomere XI yellow, pronotum bearing weak strong black macula (Figure 1). Antennae subserrate, bearing sparse scaliform setae on antennomerrs IV-XI ; antennomeres IV-IX dorsoventrally flattened (Figure 19); 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. Pronotum trapezoidal, not constricted medially, with posterior margin slightly arcuate, anterolateral angles rounded, with posterolateral angles and pronounced and round, divergent, with weakly visible longitudinal carina in anterior portion of pronotum, bifurcate posteriorly forming an areola, hardly visible. Elytra approx. 10 x longer than pronotum, slightly expanded in 2/3 portion; costae I, II, and III strongly visible. Humeral region rounded, non-pronounced (Figure 1). Aedeagus with median lobe elongate, apex acuminate, twice longer than parameres; parameres half length of phallobase; phallobase elongate with posterior margin rounded (Figure 34). Length (pronotum+elytra): 3.6 mm. Width (across humeri): 0.9 mm. Distribution. Guatemala (Figure 37).
