Prosternum transversely striate; with yellow pubescence close to procoxal cavities laterally, and on posterior half centrally; remaining surface with moderately sparse yellowish-white pubes- cence. Prosternal process with yellow pubescence partially obscuring integument. Mesoventrite with yellowish pubescence, not obscuring integument on wide central area (denser centrally, including mesoventral process), yellow, denser laterally; mesanepisternum with dense yellow pubescence close to metaventrite, darker, less conspicuous on remaining surface; mesepimeron with dark, slightly conspicuous pubescence, except more distinct narrow yellow pubescent band close to metanepisternum. Metanepisternum and sides of metaventrite with pale-yellow pubescence partially obscuring integument; remaining surface of metaventrite with sparse pale-yellow pubescence; metaven- trite with very small, moderately abundant tubercles on entire wide central area. Scutellum glabrous along central area, with tawny pubescence nearly obscuring integument laterally. Elytra. Moderately finely, abundantly punctate on basal half, gradually sparser on distal half; humeri projected forward; surface entirely irregular, with small, shin- ing tubercles throughout (some of them with short brownish seta), slightly larger, distinctly more abundant on edge between dorsal and lateral areas (especially in basal half); black semicircular macula in dorsal surface of posterior half concave, with margins slightly elevated, more so in anterior margin; apex with outer angle distinctly projected, inner margin slightly concave, and sutural angle slightly projected. Pubescence as follows: tawny, dense across basal area; brownish, interspersed with irregular tawny maculae in remaining anterior third; wide semicircular grayish-white pubescent band, from anterior third to posterior quarter, not reaching suture, starting and finishing at epipleural margin, centrally interrupted by black macula; black areas with dark, slightly conspicuous pubescence; remaining surface of posterior 2/3 irregularly variegated with grayish-white, yellowish-white, and yellowish-brown pubescence; with isolated tufts of pale-yellow pubescence at posterior 2/3 along epipleural margin (more abundant in posterior third). Legs. Pro- and mesofemora with yellowish-white pubescence not obscuring integument on peduncle and most of inferior side of club, with distinctly sparser and shorter yellowish-white pubescence on entire ventral surface, with intermixed dense pale-yellow and tawny pubescence on remaining surface; peduncles slightly arched. Metafemora with pale-yellow pubescence and tawny pubescence intermixed, with scattered small, irregular, glabrous areas, except inferior surface of club with distinctly shorter grayish-white pubescence not obscuring integument; peduncle distinctly arched. Ventral surface of protibiae sinuous, with distal area distinctly projected; metatibiae strongly arched; pubescence mostly pale-yellow interspersed with scattered small, irregular glabrous areas, except distal area with pubescence more brownish.

Abdomen. Ventrites with abundant grayish-white pubescence, not obscuring integument, except anterocentral area of ventrite I with yellow pubescence. Apex of ventrite V deeply concave, with lateral apices spined.

Material examined. PERU (New country record), Junín: Satipo province (11.4596S / 74.7915W; 1650 m), 1 male, 19.01.2017, A. Kozlov & Y. Kovaleva col. ( MZSP) .

Remarks. Paranisopodus granulosus was originally described from Panama (Chiriquí), based on a single female specimen ( Fig. 11 ). It was deposited at MNRJ and unfortunately destroyed during the recent fire (2 September 2018).

Comparing the photograph of the holotype with the male examined, it is possible to find only a minor difference (excluding those considered sexual dimorphism, as for example, the antennal length): the apex of the lateral prothoracic tubercle is distinctly truncate in the examined male ( Fig. 14 ), while it is acute in the holotype female ( Fig. 11 ). However, with only a single specimen of each sex, it is impossible to know whether this difference represents another sexual dimorphism, or is simply a variable character in the species.

As occurs in some males of P. heterotarsus Monné & Martins, 1976 , it is possible that some males of P. granulosus have the metatibiae strongly arched too. However, probably, the most common metatibial shape in males of P. granulosus should be straight, as occurs in P. heterotarsus .

According to Monné & Monné (2007) on P. hovorei Monné & Monné, 2007 (translated): “Metatarsomere I as long as II+III.” However, examination of the photograph of the holotype female shows that the metatarsomere I is longer than II–III together, apparently, about 1.3 times longer. Furthermore, males of P. heterotarsus have the metatarsomere I about twice longer than II–III together. This observation makes part of the alternative of couplet “4” from Monné & Monné (2007) problematic. However, the other differences pointed out in the same alternative of couplet allow separating the species.
