(Figures 5 a-d)  
 Description. Female. Length 12.0-14.0 mm (measured from vertex to elytral apices), width 4.8-5.3 mm (measured across humeri). Habitus as in Fig. 5a. General form elongate-oblong, moderate-sized. Integument generally ferrugineous, dark brown or black, with whitish, gray, ferrugineous, and brown pubescence; pronotal disk with whitish and ferrugineous pubescence; elytral with central band of whitish and gray pubescence; basal 1/3 and apical 1/3 of elytra with variegated whitish, gray, and ferrugineous pubescence; mesepimeron, mesepisternum, and lateral margins of humeri with dark brown or black pubescence; tibiae and metafemora with band of dark brown or black pubescence near middle.   
Head with frons roughly subquadrate, about 3 times width of one lower eye lobe (as in Fig. 5c). Eyes with lower lobes moderate-sized, oblong; narrowest area connecting upper and lower eye lobes about 2 ommatidia wide. Genae elongate, slightly shorter than lower eye lobes.  
Antennae slightly longer than body; antennal tubercles prominent, moderately separated; tubercles armed at apex with short projection; scape robust, clavate, with feeble basal groove on inner face; antennomeres III-XI slightly curved. Antennal formula based on antennomere III: scape=0.8; II=0.22; III=1; IV=0.81; V=0.81; VI=0.73; VII=0.64; VIII=0.62; IX=0.62; X=0.57; XI=0.63.  
Pronotum roughly conical, slightly narrower at base, transverse, about 1.6 times as wide as long, sides irregular, with a moderate-sized, blunt protuberance each side behind middle (Fig. 5a, d); disk with median, oval, glabrous region at basal half, adjacent to basal transverse sulcus; disk with two feebly elevated lateral tubercles; each lateral tubercle adjacent to apical transverse sulcus.  
Scutellum transverse, apex rounded; central 1/3 glabrous, outer margins fringed with grayish or whitish or ferrugineous pubescence.  
Elytra about 1.7 times as long as width at humeri (Fig. 5a, d), about 3.3 times as long as pronotal length, about 1.2 times broader basally than pronotum at widest (at middle); sides roughly parallel, slightly attenuate to apices, gradually rounded to apices at apical 1/3, apices jointly rounded; basal 1/3 of elytra with dense punctation, surface granulate-punctate; humeri prominent, anterior margin arcuate, angle with moderate-sized, obtuse tubercle.  
Venter with procoxae large, globose, not uncate; narrowest area of prosternal process between procoxae about 1/4 as wide as procoxal cavity; apex of prosternal process not visible (specimens mounted on card). Mesosternal process not visible (specimens mounted on card). Fifth abdominal sternite about 2 times as long as IV, with a median triangular impression  
Legs moderate in length; femora robust; metafemora clavate apically; tibiae slightly expanded apically; metafemora about 1/3 as long as elytra; tarsomere V about as long as I-IV combined.  
 Male. Length 11.0- 14.5 mm (measured from vertex to elytral apices), width 4.2-5.0 mm (measured across humeri). Similar to female except antennae longer, about 1.3 times as long as body; scape with distinct basal groove on inner face; genae transverse, distinctly shorter than lower eye lobes; pronotum less strongly transverse; mesosternal process subtruncate, about 1/2 as wide as mesocoxal cavity; fifth abdominal sternite about 1.5 times longer than IV, without median triangular impression.

 Etymology. We take pleasure in naming this species for Denis Faure, with appreciation for his collaboration. The epithet is a noun in the genitive case.   
 Diagnosis and Remarks. This species is distinguished from its congeners by the combination of the following characters: eyes with lower lobes slightly taller than gena (females) or distinctly taller than gena (males); pronotum with a moderate-sized, blunt protuberance each side behind middle; antennomere III in male specimens not distinctly swollen (strongly clavate). Psyllotoxus faurei is described from 18 specimens: 11 males and seven females. All known specimens were collected in French Guiana, either at light or reared from girdled branches.
