Pseudoproscopia scabra; Bentos-Pereira (2006b)

Examined material. Holotype ♀ (pres. desig.): “ Syntypus ”, “2218”, “Scabra Pará Sieber ”, “ BA000614 S01 DORSA” (MfN).

Diagnosis. Fastigium very wide in all views, with apex slightly wider than base; in dorsal view slightly convex, seemingly truncated (Figs. 96A–C). Third pair of valves very wide, with, with dorsal margin conspicuously emarginating towards apex (Fig. 96E). Basivalvular sclerite ellipsoid, with constant width (Fig. 96E).

Description. ♀ (Figs 95A–C; 96A–F). Coloration only known from dry specimen, which mostly light brown with darker areas on the thorax and abdomen (Figs. 95A–C). Head. Slightly rugose, slightly widened at the occipital margin (Figs. 96A–B). Fastigium very wide in all views, with apex slightly wider than base; in dorsal view slightly convex, seemingly truncated; nearly reaches the apical margin of the last antennomere (Figs. 96A–C). Gena gradually lightens in color towards the mouthparts (Figs. 96B–C). Transverse crest of the frons with conspicuous punctuations (Fig. 96C); subocular suture inconspicuous. Thorax. Prothorax cylindrical, slightly granular, 2.5 times longer than meso- and metathorax combined (Figs. 95A–B). Pleurosternal suture conspicuous (Fig. 95B). Mesoscutum with straight anterior margin; convex lateral margin that widens from base to apex, posterior margin convex (Fig. 95A). Metascutum with sinuous anterior margin; lateral margin nearly straight; posterior margin medially emarginated (Fig. 95A). Prosternum with two parallel vertical lines in the first and second halves. Meso- and metasternum rugose, with small granules, with anterior margin straight, lateral conspicuously sinuous, posterior margin straight (Fig. 95C). Anterior and middle leg with small spines on all margins (Figs. 95A–C). Anterior half of the posterior femur slightly widened (Fig. 95B). Posterior tibia with 9 anterodorsal spines and 15 posterodorsal spines. Abdomen. Tergite 1 rugose, trapezoidal (Fig. 95A). Tergites 2–7 rectangular in dorsal view, with all margins straight, gradually decreasing in length and width (Fig. 95A). Tergite 8 recntagular in dorsal view (Fig. 96D). Tergite 9 subtrapezoidal, with anterior margin much shorter than posterior margin; posterior margin sinuous (Fig. 96E). Tergite 10 narrow, gradually widening towards the apex (Fig. 89G). Epiproct very wide, forming a conspicuous border (Fig. 89F). Sternite 1 rugose. Sternites 2–7 rectangular in ventral view, with all straight margins, gradually decreasing in length and width. Subgenital plate with the shape of the genus, with longitudinal medial spots (Fig. 96F). Third pair of valves very wide, with, with dorsal margin conspicuously emarginating towards apex (Fig. 96E). Basivalvular sclerite ellipsoid, with constant width (Fig. 96E).

Comments. This species is now being redescribed based on the holotype specimen. It is important to highlight that Klug (1820) only mentions a single specimen for the description he used, which is the same we are providing images and we know it from the matching data in the label, same as disclosed in the original work. Furthermore, the description mentions the antenna and this is the only specimen with an antenna. There is other specimens in the MfN collection that are attributed as syntypes of Pseudoproscopia scabra. However, as the author only explicitly cited one specimen and for the reasons above, these should not be regarded as types. The “ syntype ” labels does not seem to be from the original author, as they were printed instead of handwritten. As in Proscopia, several authors attempted to describe males of this species and resulted in several synonyms. Due to this, all of the synonyms must be revised in the future, as they are very likely to belong to other species.
