Figs 12, 14D
Diagnosis
Similar to Coilodes punctipennis, it is distinguished by the presence of finer punctures on elytra and by the presence of a sharp lobe on the right side of the tegmen, reaching the base of parameres.
Etymology
Noun in the genitive singular. Coilodes ravii Basílio & Vaz-de-Mello sp. nov. is named after Ravi Basílio Dantas, nephew of the first author.

MEASUREMENTS. Length 6.4 mm. Width 3.7 mm. Body (Fig. 12A–B) convex, oval and shiny.
COLOUR. Body, yellowish brown; elytra with outer margins black.
HEAD (Fig. 12C–D). Surface slightly strigulate. Frons, in dorsal view, subrectangular; two small tubercles merged, in the middle; proximal border rounded; posterior margin as wide as the anterior one; lateral margin, straight and darker; surface without punctures. Eye barely visible dorsally. Canthus strong; distinct area expanded downwards. Clypeus subrectangular; lateral margins weakly rounded; anterior borders rounded; apex straight; setae thin and sparse, throughout the anterior margin dorsally; surface without punctures. Labrum semicircular; setae sparse, spreading along the entire dorsal border. Mandibles dorsally excavated, protruding beyond the apex of labrum. Labium with mentum subquadrate; inferior and lateral margins straight and superior margin slightly curved in the middle; disc strigulate, long setae on the margins. Maxilla subtriangular; long setae throughout surface. Antenna with 10 antennomeres; antennal club with three antennomeres; club with basal antennomere cupuliform.
PRONOTUM (Fig. 12E). Convex; strongly excavated medially; subtrapezoidal, posterior margin wider than anterior one; anterior margin straight, angles subacute; posterior margin rounded and weakly produced medially; lateral margin convex, setae and punctures absent.
SCUTELLAR SHIELD. Subtriangular; setae and punctures absent; apex punctate.
ELYTRA. Double row of longitudinal punctures, sutural stria complete, formed by thicker punctures.
VENTER (Fig. 12B). Hypomeral surface strigulate, setose; prosternum (Fig. 12B, D) elevated at midlength, transversally grooved; anterior margin straight and flat, mesoventrite and metaventrite smooth.
LEGS. Procoxa conical; surface strigulate. Protrochanter joint with the procoxa rounded, distally angulate. Profemur with posterior margin carinate. Protibia with inner margin convex; carinate; single spur, slightly curved at the apex; external margin with three larger teeth and series of smaller denticles along the entire margin. Protarsi with tarsal insertion beneath the protibial second tooth. Mesothoracic and metathoracic legs smooth. Mesotrochanter and metatrochanter subtriangular with bifurcated apex. Mesofemur and metafemur carinate on posterior margin. Mesotibia and metatibia with erect setae; apex weakly expanded; pair of spurs with sharp apex. Tarsi with five tarsomeres; tarsal claws toothed medially.
ABDOMEN. Six ventrites with recumbent setae.
GENITALIA (Fig. 12F–K). Lobe of tegmen triangular on right side, reaching the paramere bases; sclerotized region next to paramere bases; parameres asymmetrical; right paramere longer than wide, straight base and apex rounded; left paramere dislocated to ventral region, straight apex strongly curved outward.
