Figs 3, 14A
Diagnosis
Similar to Coilodes punctipennis and some C. parvulus specimens, it is distinguished from both by the presence of a dorsal lobe on the tegmen. It is also distinguished from C. parvulus by the presence of strong punctures on the elytra.
Etymology
Noun in the genitive singular. Coilodes edeiltae Basílio & Vaz-de-Mello sp. nov. is named after Edeilta Silva Basílio, mother and the main supporter of the first author.

Description
Male (holotype)
MEASUREMENTS. Length 4.9 mm. Width 3.0 mm. Body (Fig. 3A–B) convex, oval and shiny.
COLOUR. Body yellowish brown.
HEAD (Fig. 3C–D). Surface slightly strigulate. Frons, in dorsal view, subrectangular; one long tubercle in the middle; proximal border rounded; posterior margin as wide as the anterior one; lateral margin slightly arched and darker; sparse and slightly defined punctures. Eye barely visible dorsally. Canthus strong; distinct area expanded downwards. Clypeus subtrapezoidal; lateral margins weakly rounded; anterior borders rounded; apex straight; setae thin and sparse, throughout the anterior margin dorsally; punctures sparse and weakly defined. Labrum semicircular; inconspicuous medial projection; setae sparse, along the entire dorsal border. Mandibles dorsally excavated, protruding beyond the apex of labrum. Labium with mentum subquadrate; inferior margin arched; lateral and superior margins slightly rounded; disc strigulate, long setae on the margins. Maxilla subtriangular; long setae throughout its surface; maxillary palp with four palpomeres; basal palpomere curved; second and third palpomeres longer than their width; distal palpomere barrel-shaped, length equivalent to the sum of the previous three. Antenna with 10 antennomeres; antennal club with three antennomeres, basal antennomere cupuliform.
PRONOTUM (Fig. 3E). Convex; slightly excavated medially; subtrapezoidal, posterior margin wider than anterior margin; anterior margin straight, angles subacute; posterior margin rounded and weakly produced medially; lateral margin convex, setae absent; punctures thin and sparse.
SCUTELLAR SHIELD. Subtriangular; setae and punctures absent; apex punctate.
ELYTRA. Double row of longitudinal and thick punctures, sutural stria complete, formed by thicker punctures.
VENTER (Fig. 3B). Hypomeral surface strigulate, setose; prosternum (Fig. 3B, D) elevated at midlength, transversally grooved; anterior margin rounded and jagged, slight invagination in the middle; mesoventrite and metaventrite weekly strigulate.
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. 3F–K). Lobe of tegmen reaching the paramere base, slightly dislocated to left side; parameres asymmetrical; right paramere with rounded edges, base wider than apex; left paramere with wide base and sickle shaped apex.
Female
