Diagnosis
Similar to Coilodes humeralis and to C. lunae sp. nov. Distinguished from both by the presence of a perpendicular laminar structure on the internal region of the tegmen. It is distinguished from C. humeralis by the absence of a dorsal lobe on the tegmen, and from C. lunae sp. nov. by the sharp constriction next to the base of the right paramere and by the absence of a transparent region on the superior half of the right paramere.
Etymology
Noun in the genitive singular. Coilodes mayae Basílio & Vaz-de-Mello sp. nov. is named after Maya Basílio Dantas, younger niece of the first author.

Description
Male (holotype)
MEASUREMENTS. Length 5.6 mm. Width 3.6 mm. Body ( Fig. 7A–B View Fig ) convex, oval and shiny.
COLOUR. Head and pronotum dark brown; scutellar shield, venter and legs yellowish brown; elytra yellowish brown, margins dark brown.
HEAD ( Fig. 7C–D View Fig ). Surface strigulate. Frons, in dorsal view, subrectangular; one small tubercle in the middle; proximal border rounded; posterior margin as wide as the anterior one; lateral margin slightly arched; sparse punctures, restricted to region next to clypeus. Eye barely visible dorsally. Canthus strong; distinct area expanded downwards. Clypeus subquadrate; lateral margins weakly rounded; anterior borders rounded; apex straight; setae thin and sparse, throughout the anterior margin dorsally; sparse punctures. Labrum semicircular; slight medial projection; setae sparse, spreading along the entire dorsal border. Mandibles dorsally excavated, protruding beyond the apex of labrum. Labium with mentum subquadrate; inferior margin arched; lateral margins slightly rounded and superior margin 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. 7E View Fig ). Convex; strongly excavated medially; subtrapezoidal, posterior margin wider than anterior margin; anterior margin straight, weakly produced medially, 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 punctures.
VENTER ( Fig. 7B View Fig ). Hypomeral surface strigulate, setose; prosternum ( Fig. 7B, D View Fig ) elevated at midlength, transversally grooved; anterior margin rounded and slightly jagged, 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. 7F–K View Fig ). Lobe of tegmen absent; region with strongly sclerotized projection next to right paramere base, sclerotized laminar structure on inferior ventral region of tegmen, parallel to the sides of tegmen; parameres asymmetrical; right paramere longer than it is wide, base as wide as apex, strong constriction next to paramere base, gradually increasing towards the apex, rounded vertices; left paramere, wide base and apex strongly curved outward.
