(Figs. 1k, 2c)  
 Description. Small size, 7–9.5 mm long; 4–5 mm wide at humeri; integument mottled light and dark brown and black (appearing uniformly gray-brown to naked eye) except for uniformly tawny scutellum. Integument covered with moderately dense coating of tawny appressed pubescence. Head with broad, nearly flat interantennal tubercle region, antennal tubercles only slightly raised. Head with a faint, median, shallow groove just beyond vertex. Head throughout with moderately dense, shallow punctures and covered with dense appressed tawny pubescence (in places obscuring surface) and sparse, long, erect, mostly pale hairs on frons, vertex, and eye margins. Eyes average in size, coarsely faceted (about 14 facets at greatest height of lower lobe; about 6 facets across greatest width of upper lobe), deeply emarginate at insertion of antenna, lower lobe comprising about one-half of head thickness. Narrowest point between upper and lower lobes about width of 2 facets. Antenna 11-segmented, without spines, with vestiture mixture of short, tawny brown and white pubescence, with sparse, stiff, suberect hairs along most antennomeres. Antennomeres 4–11 with basal one-fifth to one-fourth distinctly annulate with pale pubescence. Scape with small, dense, confluent punctures throughout. Antennae of both sexes similar in length and form, just surpassing elytral apices in male, and slightly shorter than body in female. Third antennomere about 1.3 times as long as scape, fourth about as long as scape, and nearly twice as long as fifth. Antennomeres 5–11 short and gradually decreasing in length. Pronotum much broader than long (1.3 times as broad as long); an acute, post-medial and posteriorly directed lateral spine on each side; distinctly narrowed at base behind tubercle; width of pronotum at base about three-fourths width of elytra at base. Pronotum densely covered with small, shallow punctures, mostly separate from each other; with moderately dense vestiture of pale or tawny pubescence, in places obscuring surface. Prosternum with punctures and pubescence similar to pronotum. Prosternal process moderately broad between procoxae, strongly expanded at apex, closing procoxal cavities posteriorly. Elytra with mottled light and dark brown integument (appearing mostly uniform gray-brown to naked eye). Elytral surface covered with dense vestiture of appressed tawny and white pubescence, in places concealing surface. Elytral surface with moderately dense, regularly placed, longer, semiappressed bicolored hairs, dark at base, white at apex, arising from deeper punctures. Punctures moderately dense, deep, mostly separate. Elytral apices narrowly rounded. Scutellum subtruncate posteriorly, broadly covered with dense off-white pubescence. Legs moderate to short in length, femora extending to base of fifth ventrite; with moderately dense pubescence, including longer, appressed bicolored hairs (dark at base, white at apex); femora clavate. Venter moderately pale pubescent throughout, in places obscuring surface which has punctures of slightly smaller size, more shallow and more densely distributed than those of dorsal surface. Mesosternum with moderately broad mesocoxal process, about as wide as mesocoxa, and without lateral projections into mesocoxae. Ventrite 1 as long as 2–4 combined, which are each short, and of similar length. Fifth ventrite about as long as 2–3 combined. Fifth ventrite of female with a short, longitudinal groove at middle of base (lacking in males). Apex of fifth ventrite sinuate in females and subtruncate in males.   
 Etymology. This species epithet is a participle that refers to the uniform, ordinary appearance of the species, without any maculae, bright colors, or striking morphological features.   
 Discussion. The tribe Calliini contains many species that greatly resemble those of Desmiphorini, however, the presence of appendiculate tarsal claws in Calliini readily distinguishes them. Like Desmiphorini, the generic limits in Calliini are somewhat diffuse, and this tribe could benefit from a phylogenetic analysis that would also serve to better define (and perhaps synonymize) some genera.   
 Martins and Galileo (1990) reviewed the South American species of Drycothaea and provided a diagnosis for the genus. Based on their study, we place this new species in that genus. Characters supporting our decision include: presence of appendiculate tarsi; pronotum with an acute, post-medial and posteriorly directed lateral spine on each side; antennal scape without an apical cicatrix; third antennomere longer than the scape; elytra convex, without a longitudinal carina; and rounded elytral apices. The only other species of Drycothaea known from the Caribbean is Drycothaea guadeloupensis Fleutiaux and Sallé 1889, recorded from Guadeloupe and Dominica, Lesser Antilles (Chalumeau and Touroult 2005; Monné 2005 b; Monné and Hovore 2005). Drycothaea guadeloupensis differs from D. indistincta by having more sparse pubescence dorsally exposing most punctures, especially on the pronotum (dense and mostly uniform gray-tawny pubescence in D. indistincta); by having the pronotum only slightly broader than long (much broader than long in D. indistincta); and by having the antennae more broadly annulate at the base of most antennomeres (narrowly annulate in D. indistincta).
