Description. Body elongate, parallel-sided. Length 6.6–9.2 mm.

Body yellow, elytra with elongate black spot on each humerus and common transverse preapical black spot; apical 1/5 length of elytra yellow, lateral margins entirely yellow. Humeral spots always emarginate internally, preapical spot always emarginate centrally. Elytral pattern quite constant and only varies in depth of emargination of individual spots.

Frons with broad and low carina extending from clypeus and slightly projecting to vertex. Frons and vertex smooth, shiny, and moderately and sparsely punctate. Vertex flat and transverse, with moderately large and oval basal impression. Head moderately constricted beyond eyes. Eyes normal, large, not projecting from dorsal outline of head. Gena large, smooth, shiny and finely punctate. Mouthparts typical, not modified. Antennae moderately long, thick with two basal antennomeres sparsely pubescent, remainder densely pubescent. Antennomere I elongate, densely pubescent on ventral side and with apex slightly projecting anteriad on ventral side. Antennomere II distinctly triangular in males and globose in females. Antennomeres III–IV elongate with distinctly projecting apices on inner side, thus appearing subtriangular; V–VI with very minutely projecting apices, remaining antennomeres unmodified. In females all antennomeres from III on unmodified with rounded apices. Length ratio of antennomeres: 100: 54: 59: 52: 54: 41: 51: 45: 54: 56: 87. Antennomere III 1.1× as long as II, antennomeres IV, V, VII, VIII, X subequal in length, VI and IX distinctly shorter. Antennomeres thicker from VIII onwards, VIII–XI subquadratic, 1.2× as long as wide. Antennomere XI 0.8× as long as I and with rounded apex.

Pronotum 1.1–1.2× as wide as long, subparallel-sided, more or less distinctly constricted around midlength and slightly diverging before anterior corners. Basal corners sharp and slightly divergent, thus pronotum appears slightly wider at base than around midlength. Anterior 1/6 regularly narrowing anteriad and forming anterior corners. Anterior corners subacute, broad, and distinctly depressed thus separated from disc. Anterior margin deeply emarginate between corners, regularly convex. Setigerous pores not on tubercles, barely visible, situated anteriorly in curved points, and bearing single very long seta. Due to weakly delimited setigerous pores and quite fragile setae pronotum appears to lack setae in many paratypes. Lateral margins not explanate, slightly swollen and forming narrow and barely canaliculate ridge. Disc weakly and regularly convex without any impressions, shiny, moderately and sparsely macropunctate. Surface smooth with fine but quite visible shagreen. Basal margin bisinuate and smooth.

Scutellum subtriangular, smooth and distinctly less shiny than pronotum due to faint shagreen.

Base of elytra distinctly wider than base of pronotum. Basal margin smooth and bisinuate. Humeral angles broadly rounded and not projecting. Humeral calli distinctly convex, smooth, shiny and impunctate, not separated by explanate margin and thus forming anterior corners of elytra. Elytra overall regularly and weakly convex, smooth, moderately shiny with faint shagreen and without impressions. Punctation moderately large, arranged in ten mostly regular and not impressed rows plus scutellar row, apical 1/5 of elytra (yellow portion between apical margin and transverse black spot) irregularly punctate. Scutellar row long, formed by ca. 14 punctures and reaching to basal 1/4 of elytra. Punctures in rows more or less regularly arranged, interspaces as wide as puncture diameter or narrower. Internal rows similar, penultimate row with larger punctures and ultimate with smaller and denser punctures. Ultimate row regular without distinct vacancies. Intervals smooth and shiny, 1–2× as wide as rows, not elevated or impressed. Interval 5 and mainly 7 with several additional irregular punctures. Lateral margins narrow, barely explanate and canaliculate in central part 3/5 of length. Explanate part smooth and shagreen, impunctate. Outer margin moderately swollen and smooth, in apical 1/5 declivous. Elytral apices rounded and slightly emarginate at suture.

Prosternal collar smooth and shiny. Prosternal process broad, strongly expanded apically and with weak medial impression. Epipleura smooth, shagreen, and bare. Thoracic ventrites finely and sparsely punctate, and shagreen. Abdominal ventrites densely micropunctate and pubescent with long semiadherent setae. Ventrites I and II fused, suture indicated only laterally.

Sexual dimorphism distinct, antennomeres II–III triangular in males and globose in females. Apical margin of ventrite V emarginate in males and bisinuate with slightly pronounced central part in females.

Legs normal, unmodified, last tarsomere elongate, projecting beyond sole of penultimate. Claws simple, divergent.

Variability. Specimens from lowlands always have antennomere I with long dense pubescence on underside, while specimens from mountains have short pubescence but otherwise are morphologically similar.

Differential diagnosis. Cephaloleia fouquei sp. nov. can be easily distinguished from the two similar species by densely pubescent ventral side of antennomere I while C. renei sp. nov. and C. kolbei Weise, 1910 have antennomere I only with fundamental short and adherent pubescence. Cephaloleia kolbei ( Fig. 11 ) also differs in thick antennae with antennomeres II–IV strongly triangular and larger in size (above 10 mm). Cephaloleia fouquei has slender antennae with antennomeres II–III weakly triangular. Cephaloleia renei ( Fig. 10 ) has similar size as C. fouquei but differs also (except antennomere I) in humeral spot on elytra always emarginate and antennomeres II–III more triangular. It also has coarser and denser punctation of pronotum.

Host plant. Maranthaceae : Calathea lutea (Aubl.) E. Mey. ex Schult. ( JALINSKY et al. 2014, as C. kolbei ).

Etymology. The species is dedicated in loving memory to René Fouquè (1980–2016), friend and enthusiastic entomologist, who was world specialist on the tenebrionid tribe Stenosini .

Remarks. STAINES & GARCÍA- ROBLEDO (2014) published numerous specimens from Bolivia, Brazil, Ecuador and Peru having size 7–10 mm, yellow body with black humeral and common preapical spot on elytra, and attributed them to C. kolbei , which was until that time known only from Colombia. However, they did not examine the holotype. I did study the holotype and compared it to additional specimens with similar pattern as well as to the part of material published by STAINES & GARCÍA- ROBLEDO (2014). The holotype clearly differs from other populations published by STAINES & GARCÍA- ROBLEDO (2014) as it has very robust antennae with antennomeres II–IV strongly triangular while the other populations have antennae slen- der and antennomeres II–III barely triangular, basically only II has more or less triangular shape. Cephaloleia kolbei is also stouter and larger (length above 10.0 mm vs. 7.0– 8.5 mm, exceptionally exceeding 9.0 mm). Further comparison of specimens revealed that the material belongs to two similar yet distinct species here described as C. fouquei sp. nov. and C. renei sp. nov. Therefore all subsequent records of C. kolbei belong to one of the newly described species and C. kolbei seems to be restricted to Pacific versant of the Cordillera Occidental in Colombia.

Records from Bolivia and Peru belong to C. fouquei sp. nov. Subsequently the same specimens from Peru were again published by JALINSKY et al. (2014) and CHABOO & STAINES (2015). The record from Brazil is based on a single specimen from São Paulo de Olivença deposited in USNM, which belongs to a different species group. The specimen is most similar to C. alternans Waterhouse, 1881 but not identical.

Distribution. Bolivia: Beni, Cochabamba and Peru: Cuzco, Madre de Dios, Pasco, Ucayali.
