Furth, David G., 2019, A new species of the Neotropical mimetic genus Cerichrestus Clark from Costa Rica (Coleoptera: Chrysomelidae: Alticinae): An example of how unknown is biodiversity, Israel Journal of Entomology (Oxford, England) 49 (2), pp. 179-194 : 186-188

Scutellum : triangular and black.

Elytra: elongate-rectangular, parallel-sided; humeral calli evident but not bulging; punctation striate with one sutural short stria and 10 distinct striae of medium coarse punctures. Color black centrally with sublateral, longitudinal, yellow/orange stripe [6 specimens with this yellow sublateral stripe melanized indicated in the material examined section], extreme lateral and epipleural areas black, extending to apex and joining narrowed medial black band. In dorsal view wide (from suture to striae 6) solid black, median, longitudinal stripe parallel-sided with lateral yellow longitudinal stripes much narrower ( Figs 1, 2).

Venter: usually entirely black or dark brown, sometimes abdominal sternites lighter (yellow) with sparse, fine pubescence; front coxal cavities closed; front coxae yellow, prominent, bulging, sub-conical. Male 5 th sternite only with slight medial, apical, rounded lobe, often difficult to see unless apical sternite separated from apical tergites (7 and 8), 8 th tergite with apparent medial, V-shaped, apical invagination (notch), often curled ventrally over apex of 5 th sternite. Female: apex of 5 th sternite, 7 th, 8 th tergite continuously rounded or slightly pointed.

Legs ( Fig. 2): fore and middle tibiae usually black dorsally, usually lighter (yellow) ventrally, rarely all yellow, hind tibia yellow; fore and middle femora yellow, usually darkened dorsally; metafemora with ventral half to two-thirds yellow, darkened dorsally. Male first foretarsal segment not swollen or enlarged. Metatarsal length more than two-thirds as great as metatibial length; apical metatarsal segment dark brOwn, verY glObOselY swOllen; fOretarsus ca. 40–50 % as lOng as fOretibiae; middle tarsi ca. 60 % as lOng as middle tibiae; metatibial apeX enlarged with inner (medial) lobe extended, somewhat rounded but with short teeth, with outer/lateral large prominent dark spine metatibial apex, also with ca. 6 or more serrate teeth; metatibia with dorsal margins sulcate. Metatarsi inserted subapically onto metatibiae. Tarsi dark brown.

Genitalia: Male: aedeagus, symmetrical in ventral view ( Figs 4), although in ventral view it appears rotated slightly left giving a somewhat asymmetrical impression: Female: spermatheca as in Fig. 5. Vaginal palpi as in Fig. 6.
