Figs 1–12View FIGURES 1–10View FIGURES 11–12

Xylographus dentatus Pic 1922: 7  (original description); Sandoval-Gómez et al. 2014: 39 (new replacement name). Typelocality: Republic of the Congo.

Diagnosis. Pronotum bearing an impunctate region at midline in both sexes. Anterocephalic edge in males laterally and slightly produced forward forming two subtriangular plates ( Figs. 2–4 View Figure ); pronotal anterior portion devoid of concave impression and anterior edge projected forward into two subtriangular plates ( Figs 1–2 View Figure ). The most remarkable feature is the morphology of male genitalia, with penis about twice as long as tegmen, very elongate, subparallel-sided, with apex hook-shaped and base spatula-shaped ( Figs 9–10 View Figure ).

Redescription, male lectotype ( Figs 1–5 View Figure ). Adult apparently not fully pigmented, but in good conditions. Measurements in mm: TL 2.84, PL 1.10, PW 1.47, EL 1.74, EW 1.46, GD 1.13. Ratios: PL/PW 0.75, EL/EW 1.19, EL/PL 1.58, GD/EW 0.77, TL/EW 1.95. Body elongate, convex, dorsum and venter reddish dark brown; antennae a bit lighter (except for the slightly darker antennal club), palpi and tarsi a bit lighter; dorsal vestiture dual, consisting of yellowish suberect bristles and decumbent setae, both in the pronotum and elytra, the suberect bristles easily discernible in low magnifications (<50x); ventral vestiture of yellowish decumbent setae, most abundant on abdominal ventrites. Head ( Fig. 4 View Figure ) concealed by pronotum when seen from above; dorsum forming a kind of elevate triangular zone at the center of the disc; the punctures closer to the anterocephalic area are shallower and separated from each other by one to two puncture-widths, the punctures closer to the occipital region are deeper and separated from each other by one puncture-width or less, both punctures with a suberect bristle (~ 0.02 mm) arising from each one; interspaces, microreticulate; anterocephalic edge projected forward into two subtriangular plates with rounded apex; epistomal sulcus complete and very easily distinguishable. Antennae with ten antennomeres, lengths as follows (in mm, left antenna measured): 0.11, 0.07, 0.06, 0.04, 0.03, 0.02, 0.02, 0.09, 0.09, 0.12 (FL 0.15 mm, CL 0.20 mm, CL/FL 1.33). Eyes coarsely faceted; each bearing about 90 ommatidia; GW 0.22 mm. Gula 0.30 times as wide as head. Pronotum ( Fig. 5 View Figure ) with coarse, moderately deep and single punctation, with a short impunctate region at midline beginning about four punctures from the posterior edge and extending until center; punctures distributed irregularly, separated from each other by one puncture-width or less; interspaces, smooth; vestiture distinctly dual, consisting of yellowish short (~ 0.02 mm) decumbent setae and long (0.03–0.04 mm) suberect bristles; anterior edge projected forward into two subtriangular plates with rounded apex; lateral edges barely crenulate and explanate, not visible when seen from above, except for the posteriormost portion. Scutellar shield subtriangular, bearing a few punctures and decumbent bristles; BW 0.20 mm and SL 0.10 mm. Elytra with non-seriate, dual punctation; macropunctures coarse, irregularly distributed, moderately deep, about twice as large as micropunctures; punctures separated from each other by one macropuncture-width or less; interspaces, smooth; vestiture distinctly dual, consisting of yellowish short (~ 0.02 mm) decumbent setae and long (0.03–0.04 mm) suberect bristles, both arising from micropunctures. Metathoracic wings developed, apparently functional. Hypomera with sparse, shallow punctation; each puncture bearing a fine decumbent seta; interspaces, microreticulate. Prosternum in front of coxae carinate; subglabrous; interspaces, microreticulate. Prosternal process conspicuously narrow near base and noticeably expanded to apex; width about half of its length and about as long as prosternum disc at midline; apex rounded. Protibiae with maximum width about one-fourth of its length; apical edge devoid of spines; outer apical angle projected into a small tooth. Meso- and metatibiae without spines in apical edge, outer apical angle not project into a small tooth. Metaventrite with sparse, shallow punctures; interspaces, microreticulate; discrimen about half the length of metaventrite at midline. Abdominal ventrites with moderately deep, coarse punctures, separated from each other by one puncture-width or less and each bearing a yellowish decumbent seta; interspaces, microreticulate; length of ventrites (in mm, from base to apex at the longitudinal midline) as follows: 0.22, 0.16, 0.15, 0.15, 0.20; first abdominal ventrite bearing a margined, circular sex patch located posterad of center, with a transverse diameter of 0.07 mm. Male terminalia ( Figs 7–10 View Figure ) with sternite VIII ( Fig. 7 View Figure , in a specimen from Kisantu) subquadrate, bearing long setae at posterior corners; anterior portion membranous. Tegmen ( Figs 9–10 View Figure , tegmen and penis shown together; extracted from lectotype and from a male from Kisantu, respectively) about 3.7x as long as wide, sides straight and almost parallel; base subrounded. Basal piece ( Fig. 8 View Figure , in a male from Kisantu) triangular. Penis ( Figs 9–10 View Figure , shown together with tegmen) subparallel-sided, about 2x as long as tegmen and about 19x as long as wide; apex hookshaped and base spatula-shaped.

Female, paralectotype ( Figs 11–12 View Figure ). Similar to males but devoid of an abdominal sex patch, or cephalic and pronotal plates; cephalic anterior edge truncate; pronotal anterior edge rounded.

Variation. Males, measurements in mm (n = 6, including the lectotype): TL 2.33–3.00 (2.76 ± 0.29), PL 0.83– 1.25 (1.03 ± 0.17), PW 1.18– 1.60 (1.43 ± 0.18), EL 1.50–1.88 (1.72 ± 0.15), EW 1.18–1.60 (1.44 ± 0.17), GD 0.90–1.15 (1.08 ± 0.12), PL/PW 0.68–0.78 (0.72 ± 0.04), EL/EW 1.08–1.28 (1.20 ± 0.19), EL/PL 1.38–1.91 (1.69 ± 0.19), GD/EW 0.72–0.77 (0.75 ± 0.02), TL/EW 1.86–1.98 (1.92 ± 0.05).
