description: Chiriquibia Bates, 1889   
 Chiriquibia Bates 1889: 344. Type species: Allorrhina insignis Janson 1888: 119, by monotypy.   
 When Bates (1889) described this genus, he knew only males. He distinguished Chiriquibia by its large size, color, distinctive markings, and absence of a central, horizontal frontal horn that precluded it from being included in Allorrhina Burmeister, 1842 and Tiarocera Burmeister, 1842 where males have such a horn. The horn is also present in females of Chiriquibia and Tiarocera but not in the females of Allorrhina. Bourgoin (1912) was the first to describe the female of C. insignis, and he indicated his small female was concolorous.   
 Description. Form elongate, subparallel, robust, dorsoventrally flattened. Length 28–33 mm. Color shiny dark reddish brown with creamcolored marks on lateral margins of pronotum, a single spot on each elytron, 2 spots on the pygidium, and transversely elongated lines on abdominal sternites 1–5; tarsi and abdominal sternites piceous to black. Head: Frons and clypeus with long, dense, tawny setae (1 male with black setae) and with weakly tumescent, longitudinal ridge at center, surface slightly depressed either side of tumescence. Frons on each lateral margin above antennal insertion with short, pointed, anteriorly projecting horn or acute tooth in both sexes. Clypeus transversely subquadrate, apex subtruncate and with short, erect, bifurcate horn in both sexes. Antenna with 10 antennomeres, club distinctly longer than antennomeres 2–7. Pronotum: Subtrapezoidal, widest near base, gradually convergent to anterior angles, basomedian lobe strongly produced posteriorly, lobe covering all but tip of scutellum. Sides with slender, completae marginal bead. Elytra: Widest at base, posthumeral emargination distinct. Bead present on lateral margins. Surface with punctate rows on median half, becoming rugopunctate on lateral half. Pygidium: Surface with dense, concentric, strigae, setigerous, setae long, dense, tawny; 1 male with black setae. Venter: Mesometasternal process, in lateral view, moderately protuberant, subparallel with ventral axis of body, apex narrowly rounded (Fig. 7). In ventral view, mesometasternal process broad with broadly rounded apex. Abdominal ventrites 1–5 nearly impunctate in central third, lateral thirds with sparse, moderately large, ocellate punctures. Legs: Males with protibia slender and with apical tooth only, protibia if females distinclty tridentate. Parameres (Figs. 9–10): In caudal view, form subrectangular, elongate, apices broadly rounded with small, subapical tooth on lateral edge.
