Note. In the first comprehensive revision of South American trogids, Vaurie (1962) mentioned that the type specimen of Trox gemmifer Blanchard, 1847, presumably deposited in MNHN, was ‘not located’ (Vaurie 1962, p. 120). During the examination of trogid material housed in MNHN by the first author (VCS), the type specimen of T. gemmifer was found based on the typical green label with Blanchard’s handwriting ‘ gemmiferus ’ and d’Orbigny’s labels indicating where the material was collected. Curiously, this type specimen was found as a paratype of Trox haafi, described by Vaurie (1962).
Considering that the description of T. gemmifer by Blanchard (1847) is vague, and its diagnosis could potentially apply to several species,such Trox argentinus, Polynoncus burmeisteri, and P. pittinoi, Vaurie (1962) noticed numerous morphological features that led her to describe Trox haafi as a new species. The presence of hypemeron covered by black setae (Figure 31c), for example, is one of the diagnostic characteristics for T. haafi presented by Vaurie (1962), but earlier omitted by Blanchard (1847) when T. gemmifer was described.
Here, after 60 years, we document this mistake carried out by Vaurie (1962), proposing Trox haafi as a junior synonym of T. gemmifer. Also, we here describe Polynoncus pseudogemmifer sp. n. to accommodate the species historically identified as ‘ Polynoncus gemmifer ’ by several authors (ie Scholtz 1982, 1990; Diéguez and Gómez 2004; Diéguez 2008; Gómez 2008; Zidek 2013, 2017; Smith 2017; Costa-Silva and Diéguez 2020).
Differential diagnosis. Polynoncus pseudogemmifer is morphologically similar to P. argentinus. However, the two species can be separated considering the shape of medial ridges of pronotum: the pronotal ridges in P. pseudogemmifer do not form a remarkable triangle in the middle (Figure 4h), while in P. argentinus, the shape of pronotal ridges form a well-defined triangle with a shallow fovea in the middle (Figure 4g).
Polynoncus pseudogemmifer can be easily separated from P. argentinus by the male genitalia, where the former species has the lateral margins of median lobe symmetrical in dorsal view (asymmetrical in P. argentinus) and notably constricted near the apex in lateral view (vs no such constriction in P. argentinus). Drawings and photographs of the male genitalia of P. pseudogemmifer can be found in Pittino (1987, p. 381, figs. 12–13 and 20–21; referred to as P. haafi) and Costa-Silva and Diéguez (2020, p. 269, figs. 10–11; referred to as P. gemmifer), respectively.For details of species description, see Vaurie (1962, p. 120) and Scholtz (1990, p. 1430).
Description of holotype. Size: Length: 12.6 mm, width: 7.0 mm (Figure 60). Colour: dark brown. Body covered by velutinous surface and shiny elytral tubercles. Head: apex of clypeus bent down, forming right angle with the disc; posterior margin of clypeus slightly emarginate in dorsal view (Figure 60a). Antennae and mouthparts with black setae. Pronotum: transversal, about 1.72 times wider than long; pronotal surface sparsely but distinctly punctate. Pronotal ridge incomplete, not forming a well-defined triangle at the middle (Figure 4h); basal and lateral-basal tubercles obsolete; antero-lateral tubercles visible, distinct. Lateral margin smooth. Hypomeron glabrous. Scutellum: elongate, almost twice as long as wide, margins recurvate. Elytra: Length almost 3 times longer than pronotum; humeral calli proeminent. Tubercles of the 3°, 5°, 7° and 9° (odd-numbered) elytral costae bigger than others. Second elytral costae also tuberculate; fourth elytral costae tuberculate near the base and granulate in rest; sixth and eighth elytral costae all granulate. Legs: Protibia with apex bidentate. Outer margin with one median tooth and poorly crenulated until base. Right protarsus missing. Apex of mesotibia with pointed apical tooth on outer ventral margin (as in Figure 4c); outer margin of mesotibia and metatibia slightly arched; serrate. Male genitalia: Symmetrical. Median lobe flattened laterally and constricted near to the apex in lateral view. Pars basalis widely membranous dorsally. For a comprehensive and complementary description, see Vaurie (1962, p. 120) and Scholtz (1990, p. 1430) plus the genitalia drawings and high-quality images by Pittino (1987, p. 381) and Costa-Silva and Diéguez (2020, p. 269), respectively.
Geographic distribution. Polynoncus pseudogemmifer seems to be widely distributed in Argentina between Salta and the Patagonian Steppes of Chubut (Figure 61). Vaurie (1962) mentioned records from Brazil and Chile, without further information about the specific locality. Diéguez (2008) refutes the occurrence of this species in Chile, noticing that this report was based on a misidentified specimen. We studied one specimen with an old label from Chile housed in MNHN that corresponds to P. pseudogemmifer sp. n., probably the same one earlier studied by Vaurie (1962). Even though it became a paratype of P. pseudogemmifer sp. n., this specimen was probably mislabelled and the record from Chile should be treated with caution until new data is acquired for the country.
The specimen examined by Vaurie (1962) from Brazil (Santa Catarina) was not found, nor was any specimen from Brazil examined during this study.
Scholtz (1990) included Uruguay in the geographical distribution of ‘ P. gemmifer ’ (now P. pseudogemmifer) based on two specimens studied. After examining the same specimens earlier studied by Scholtz (1990) housed in MCZ, we confirm that both specimens are P. argentinus.
Etymology. The specific name is a combination of the Greek ‘ pseudo ’ (false) and ‘ gemmifer ’, the epithet of Polynoncus gemmifer. The name is referring to the species having been historically misidentified as Polynoncus gemmifer.
