Diagnosis
Coilodes humeralis is similar to C. lunae sp. nov., C. mayae sp. nov., and C. niger stat. rev. It differs from them by presenting a subtrapezoidal clypeus with angulate anterior margin, pronotum with rounded lateral margins, and base as wide as apex, besides the presence of a lobe of the tegmen reaching the paramere base.

Redescription
Male
MEASUREMENTS. Length 5.5–8.7 mm. Width 3.0– 5.1 mm. Body (Fig. 5A–B) convex, oval and shiny.
COLOUR. Body ranging from black to dark brown; elytral disc might have yellowish brown spots throughout surface or just on humerus.
HEAD (Fig. 5C–D). Surface slightly strigulate. Frons, in dorsal view, subrectangular; two small tubercles in the middle or one long tubercle formed by the fusion of the small ones; proximal border rounded; posterior margin narrower than the anterior; lateral margin straight; sparse punctures. Eye visible dorsally. Canthus strong; distinct area expanded downwards. Clypeus subtrapezoidal; lateral margins weakly rounded; anterior borders angulated; apex straight; setae thin and sparse, throughout the anterior margin dorsally; sparse and slightly defined punctures. Labrum semicircular; setae sparse, spreading along the entire dorsal border. Mandibles dorsally excavated, protruding beyond the apex of labrum. Labium with mentum subquadrate; superior and inferior margin straight; lateral margins slightly rounded; 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. 5E). Convex; excavated medially; posterior margin as wide as anterior margin; lateral margins strongly convex; midlength usually longer than the anterior and posterior margins; anterior margin strongly arched, angles subacute; posterior margin rounded and weakly produced medially; setae absent; punctures thin and sparse.
SCUTELLAR SHIELD. Subtriangular; setae and punctures absent; apex punctate.
ELYTRA. Double row of longitudinal punctures, sutural stria complete, formed by thicker punctures.
VENTER (Fig. 5B). Hypomeral surface strigulate, setose; prosternum (Fig. 5B, D) elevated at midlength, transversally grooved; anterior margin rounded and 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. 5F–K). Lobe of tegmen reaching the paramere base, slightly curved to left side; parameres asymmetrical; right paramere base as wide as apex, edge rounded; left paramere with wide base and apex sickle-shaped.
Female
Length 5.7–8.3 mm. Width 3.2–4.6 mm.
Geographical distribution
Brazil (Distrito Federal, Minas Gerais, Espírito Santo, Mato Grosso do Sul, São Paulo, Rio de Janeiro, Paraná, Santa Catarina, Rio Grande do Sul); Chile? [questionable distribution]; Paraguay (Amambay, Caazapá, Misiones); Argentina (Misiones) (Fig.14 B) (Mannerheim 1829; Perty 1830; Westwood 1846; Ocampo & Ballerio 2006; Rodrigues et al. 2013; Santos et al. 2017; Uchoa & Rodrigues 2019; label data).
Biological data
Species collected in: human and bovine faeces; and direct association with decomposing meat of pig, chicken, and fish (Rodrigues et al. 2013; label data). Collected during the day. Many specimens were collected in suspended traps using fish as bait, FIT; and with ovitrap for mosquitoes. This demonstrates that C. humeralis has a good flight ability (Santos et al. 2017; label data; first author’s personal observation). In addition, the species seems to have stridulating behaviour and the ability to bury itself (probably as a defense mechanism) (first author, personal observation).
Remarks
Hybosorus gibbus Perty, 1830 is the type species as designated by Westwood (1846), although it is a junior synonym of C. humeralis (Mannerheim, 1829).
Coilodes chilensis Westwood, 1846 was described from a single specimen with distribution attributed to Chile. After this, no other Coilodes was collected at this locality. Due to the absence of non-type material from this country, and to the Chilean ecological particularities, different from the rest of the Neotropical Region, this distribution is considered suspicious. There is a possibility that the specimen was collected in another South American country during an expedition, and it was mislabelled.
Coilodes testaceus Pic, 1928 was cited as a variation of C. gibbus (see Art. 45.6.4. of the ICZN Code, ICZN 1999) and Ocampo & Ballerio (2006) synonymized it with Coilodes gibbus.
A lectotype of C. humeralis is here designated because the original description (Mannerheim 1829) did not designate a holotype or specify how many specimens were examined.
