Colobothea darienita sp. nov. holotype female: 1. dorsal habitus; 2. ventral habitus; 3. lateral habitus; 4. head, frontal view; 5. abdomen, ventrite 5. 6. Colobothea aleata Bates, 1885 , dorsal habitus. 7. Colobothea parcens Bates, 1881 , dorsal habitus. Measurements (mm) ( Holotype female): —Total length, 12.0; —Prothoracic length, 2.0; —Anterior Prothoracic width, 3.4; —Posterior and maximum prothoracic width, 4.7; —Elytral length, 8.7; —Humeral width, 5.0. Etymology. Named after the province ( Darién , Panama ) where the holotype was collected. Remarks. Colobothea darienita sp. nov. looks similar to two other Central American species: Colobothea aleata Bates, 1885 ( Fig. 6 ) and Colobothea parcens Bates, 1881 ( Fig. 7 ) ( Giesbert 1979 ; Figs. 10 and 15 , dorsal habitus). However, the prothoracic and elytral shapes are very different between them. In C. aleata , pronotum is slightly rounded, slightly wider at base, elytra more than twice as long as width across humeri, sides vertical, nearly straight, defined above by distinct carinae, elytral apices with outer angles stoutly spined, inner angle feebly rounded. In C. parcens , pronotum is nearly rounded, widest behind middle, elytra twice as long as width across humeri, sides vertical not straight, humeral carinae obtuse, nearly straight, tapering feebly to elytral apex. Another important difference is the pattern and thickness of the maculae on the pronotum and elytra. In C. darienita , the pronotum have a central whitish pubescent spot, and two linear series of four whitish pubescent spots on either side of the middle. In C. aleata , pronotum has a long, moderately wide antemedial pubescent vittae with a linear series of four whitish pubescent spots on either side of middle and two whitish pubescent bands on the posterior half, while in C. parcens , the pronotum has a pair of nearly parallel white vittae which are transversely connected at base, and a slender white vitta at lateral margin of disc on each side, not reaching base or apex. The elytral pubescent pattern in C. darienita is similar to that of C. parcens ; however, the elytral pubescent maculae in C. darienita are narrower.
