The complete samples include 203 specimens of this fragile species, of which only one third of them have been listed as paratypes. Remaining specimens were taken into account for seasonality (Graph. 2).  
 Description. Male (Fig. 10). General aspect slender; integument testaceous with dark areas on femora; posterior edge of profemora, apex of mesofemora, and metafemora (except posterior edge) mostly dark.   
Head finely punctate, with very short recumbent setae. Mandibles short, black at inner face and apex. Labrum trapezoidal, depressed at anterior margin. Clypeus very narrow. Frons triangular and transverse, slightly depressed. Antennal tubercles barely elevated. Coronal suture visible towards superior interocular space. Eyes with inferior lobe nearly reaching the inferior side of head; upper lobe reduced, joined to lower margin by five rows of ommatidia; upper interocular space 3 times wider than one upper lobe. Antennae surpassing elytral apex at antennomere VII, covered with long setae, more numerous on inner side; scape slightly enlarged dorsally, coarsely punctate; antennomeres more finely punctate, cylindrical, barely enlarged apically; antennal formula reported to scape: I=1.0; II=0.3; III=2.5; IV=2.7; V=2.5; VI=2.1; VII=1.8; VIII=1.6; IX=1.4; X=1.3; XI=1.3; XII=1.1.  
Prothorax 1.4 times longer than wide; base slightly constricted, covered with homogeneous punctures (except anterior half of prosternum), and short, sparse yellowish setae, with only a few long erect setae in central area of disc and laterally; disc with two small depressions and two longitudinal darker stripes (integument more sclerotized), not reaching apex nor base; basal margin emarginate in front of scutellum. Procoxae rounded and prominent. Prosternum transversally sulcate, distinctly depressed at anterior half. Prosternal process basally triangular, then laminiform, reaching 3/4 length of procoxae.  
Scutellum small, sub-quadrangular with rounded apex. Elytra long, 3.8 times longer than humeral width; sides parallel on basal half, then regularly narrowing towards apex; apex emarginate and barely dehiscent; integument covered with thin, golden recumbent setae emerging from thin and dense punctures, sparse long erect setae from deeper punctures. Metasternal sulcus visible on posterior 2/3.  
First ventrite acuminate between metacoxae; ventrites with fine punctures and sparse semi-erect setae. Legs covered with long semi-erect setae; protibiae with short and fine setae on underside; tarsal formula: I> II+III; protibiae curved; mesotibiae and metatibiae slightly sinuate near base. Parameres of tegmen (Fig. 16). Totally fused small parameres with rounded apex and 2 thin brushes of setae at apex.  
 Female (Fig. 11). Habitus more robust; antennae shorter, antennomere IX surpassing elytral apex; prothorax wider, 1.2 times longer than wide; elytra wider, 3.7 times longer than humeral width.   
 Graph 1. Seasonal occurrence (wet season from January to June; dry season from July to December) for Atenizus apicalis sp. nov. and Atenizus simplex Bates, 1884.   
 Dimensions. In mm (male/female): total length, 6.8–9.0/7.2–10.3; humeral width, 1.3–1.5/1.4–2.0.   
 Etymology. Allusive to the color of the legs.   
 Remarks. All specimens of this new species have been collected on two close places located on the first hills after the coastal plain. It could be either a rather common species not well attracted to usual traps, as most specimens have been collected with a new kind of light trap described in material and methods, or a species associated with localized host tree. Another reason for its apparent scarcity in collections is that it shows a low peak (Graph 2) during the end of the wet season, a particularly unfavorable (and uncomfortable) period for longhorn collecting (Dalens and Touroult 2010).
