Paratrichapus javanus (Pic, 1937) Figs 13���25 Xylographus javanus Pic 1937: 304 (original description); Sandoval-G��mez et al. 2014: 40 (transference to Paratrichapus). Type-locality: Goenoeng Tangkoeban Prahoe, Java, Indonesia. Xylographus javanus var. rufomarginatus Pic 1937: 304 (original description); Sandoval-G��mez et al. 2014: 40 (junior synonym of Xylographus javanus). Type-locality: Goenoeng Tangkoeban Prahoe, Java, Indonesia. Diagnosis. Paratrichapus javanus can be distinguished from all other known species of the genus by the combination of the following features: comparatively larger body (length at least 3.50 mm); metatibiae very expanded and rounded with around 26 spines separated from each other by less than half spine-width (Fig. 18) and males bearing two tubercles in the anterocephalic edge with two tufts of bristles between them (Fig. 16). Redescription, male lectotype (Figs 13���18). Adult fully pigmented; lacking both antennae, both profemur, both protibiae and all tarsi. Measurements in mm: TL 4.19, PL 1.65, PW 1.98, EL 2.55, EW 2.13, GD 1.95. Ratios: PL/PW 0.83, EL/EW 1.20, EL/PL 1.55, GD/EW 0.92, TL/EW 1.97. Body elongate, convex, shiny, dorsum black; venter brownish black; palpi reddish brown; dorsal vestiture of pale yellowish minute decumbent and long suberect setae easily discernible in medium magnifications (70x); ventral vestiture of pale yellowish slender setae easily discernible in medium magnifications (70x). Head (Fig. 16) concealed by pronotum when seen from above; dorsum with coarse punctures, separated from each other by one puncture-width or less, with a slender seta (0.06��� 0.07 mm) arising from each puncture; interspaces, smooth; anterocephalic edge bearing two tubercles with two tufts of bristles between them. Antennae lost in all examined male specimens. Eyes coarsely faceted; each bearing about 115 ommatidia; GW 0.28 mm. Gula 0.56 times as wide as head. Pronotum (Fig. 17) with moderately deep, single punctation; punctures distributed irregularly, separated from each other by one puncture-width or less; interspaces, smooth; vestiture consisting of short (0.03���0.04 mm) decumbent setae in all dorsum and long (0.09��� 0.17 mm) suberect setae just near lateral edges, representing a transition zone between dorsal and ventral vestiture; anterior edge rounded with an slight emargination in the middle; lateral edges not crenulate, not explanate and not visible when seen from above. Scutellar shield triangular, bearing a few minute punctures and apparently devoid of setae; BW 0.26 mm and SL 0.14 mm. Elytra with non-seriate, moderately deep, single punctation; punctures separated from each other by two punctures-widths or less; interspaces, smooth; vestiture consisting of short (0.03��� 0.04 mm) decumbent setae in all dorsum and long (0.09���0.17 mm) suberect setae just near lateral edges, representing a transition zone between dorsal and ventral vestiture. Metathoracic wings developed, apparently functional. Hypomera with sparse, coarse punctation; each puncture bearing a slender seta (~ 0.12 mm) and microreticulate interspaces. Prosternum in front of coxae concave; interspaces, microreticulate. Prosternal process laminate, 1.05x as long as prosternum at midline; apex acute. Protibiae in a male paralectotype, approximately three times as long as broad and expanded near apex; devoid of a clear distinction between outer and apical edges; bearing socketed spines (around 16) from about the middle of the outer edge to the apical edge. Meso- and metatibiae (Fig. 18, left metatibia) approximately three times as long as broad; widest at middle; with distinct apical and outer edges; outer edge almost straight; apical edge very expanded and rounded, bearing socketed spines (around 26) separated from each other by less than half spine-width. Metaventrite with sparse, coarse punctures; interspaces, microreticulate; discrimen absent. Abdominal ventrites with moderately deep, coarse punctures, separated from each other by one puncture-width or less and each bearing a slender seta; interspaces, microreticulate; length of ventrites (in mm, from base to apex at the longitudinal midline) as follows: 0.45, 0.17, 0.15, 0.14, 0.25; first abdominal ventrite without a sex patch. Male terminalia in a paralectotype (Figs 22���25) with sternite VIII (Fig. 22) with posterior edge rounded, bearing short setae at middle and long setae at corners; anterior portion membranous. Tegmen (Fig. 24) about 3x as long as wide, concave; sides straight and almost parallel, converging to apex which is rounded and covered by sensillae; base subtriangular. Basal piece (Fig. 23) semicircular, about 1.5x as wide as long. Penis (Fig. 25) subparallel-sided, about 0.6x as long as tegmen and about 4x as long as wide; bearing two struts not linked at base, curved inwardly and with two-thirds the length of penis; base and apex membranous and with a row of sensillae along each side of the ejaculatory duct. Female paralectotype. Similar to males but devoid of anterocephalic tubercles and tuft of bristles. Variation. Males and female, measurements in mm (n = 3, including the lectotype): TL 3.72���4.19 (4.03 �� 0.27), PL 1.49���1.65 (1.55 �� 0.09), PW 1.79���1.98 (1.88 �� 0.10), EL 2.22���2.69 (2.48 �� 0.24), EW 1.88���2.13 (2.01 �� 0.13), GD 1.80���1.95 (1.88 �� 0.08), PL/PW 0.81���0.83 (0.82 �� 0.01), EL/EW 1.18���1.33 (1.24 �� 0.08), EL/PL 1.47��� 1.81 (1.61 �� 0.18), GD/EW 0.89���1.00 (0.94 �� 0.06), TL/EW 1.97���2.07 (2.01 �� 0.05).

Paratrichapus javanus is the largest species of the genus. Unfortunately, only the type-series is known. The male paralectotype (Fig. 20) is the smallest individual of the species and it is in better condition than the lectotype. The female paralectotype was examined in the MNHN and carefully compared to the lectotype and paralectotype loaned by us.
