Type specimen examined. LECTOTYPE HERE DESIGNATED. (MNHN – Figure 36) First label [green]: ‘goyaz’ [handwitten]. Second label [light brown with black border]: ‘Ex-Musӕo / 1892/ 1892’ [vertically]. Third label [blue, handwritten]: ‘gemingeri / Harold’. Fourth label [white, typeset]: ‘MUSEUM PARIS / 1952 / coll. R. OBERTHÜR’. Fifth label [red, typeset]: ‘SYNTYPE’. Sixth label [white, typeset]: ‘ SYNTYPE / Polynoncus / gemmingeri (Harold 1872) ’. Seventh label [white, typeset]: ‘MNHN / EC9641’. Eighth label [red with black border, printed]: “ LECTOTYPE / Trox gemmingeri / Harold, 1872 / des. V. Costa-Silva, 2022” (Figure 36c). Type locality: ‘Goyaz’ [Goiás], Brazil. Probably in the east, near the territorial limit between Goiás and Minas Gerais. The type series was collected by the German naturalist Johann Baptist Ritter von Spix (1781– 1826) during his travels to South America between 1817 and 1820 (Papavero 1971; also see von Spix and von Martius 1823, 1828, 1831).
Differential diagnosis. This species is most similar to P. brasiliensis,but the two can be easily separated by the following characteristics:absence of subhumeral carina,which is present in P. brasiliensis (Figure 14b); tubercles on the odd-numbered costae rounded and punctate, while they are elongate in P. brasiliensis; the pronotal ridges not fused with the basal tubercle in P. gemmingeri and fused in P. brasiliensis; the meso- and metatarsus with claws longer than first respective tarsomere in P. gemmingeri and of the same length or less in P. brasiliensis. The male genitalia of the two species are also distinctive. For details of description, see Vaurie (1962, p. 128) and Scholtz (1990, p. 1440).
Geographic distribution. This species is widely distributed in the southern half of South America. It is recorded from Brazil, Peru, Bolivia, Paraguay, Uruguay and Argentina (Figure 37). The geographical distribution of P. gemmingeri in those countries matches with the earlier revisions of the group conducted by Vaurie (1962) and Scholtz (1990). However, this study expands the geographical distribution of this species based on more than 450 examined specimens.
Ratcliffe (2002) cited this species from Panama, but without further information on the specific locality or the repository where the specimen is housed. To date we have not seen or studied specimens of P. gemmingeri occurring north of 10°S. We thus treat this record from Panama as dubious.
