| ABSTRACT. Coptochilus Amyot & Serville, 1843 is distinguishable from the other Neotropical Scutelleridae by the dorsally concave head, with lateral margins of mandibular plates elevated. Here we describe and revise the species of Coptochilus based on general and genital morphological traits. Coptochilus castaneus (Dallas, 1851), once synonymous with C. ferrugineus Amyot & Serville, 1843, is revalidated, and a new species, C. morrisi, is described from French Guiana. A key to the five species in the genus is provided. |
