Thalthybius (Prionothalthybius) Perrieri Brölemann, 1909a:334 (nomen nudum); Brölemann, 1909b:415-417.
Thalthybius (Prionothalthybius) perrieri: Chamberlin, 1914:153, 204; Bücherl, 1942a:205; Bücherl, 1942b:352; Kraus, 1957:367.
Thalthybius perrieri: Attems 1929:105; Verhoeff, 1941:70.
Ityphilus perrieri: Pereira et al., 1994:163, 166, 167; Pereira et al., 1995:413; Pereira & Minelli, 1996:110; Pereira et al., 2000:8; Foddai et al., 2000:155; Bonato et al., 2007:3.
Remarks: In the original description of the species, Brölemann (1909b:417) says of the ultimate leg-bearing segment: “Sternite en trapèze, large de base; sa surface est semée de sétules courtes et clairsemées”. “Son prétergite n’est pas divisé, il porte une rangée de sétules”. But the latter statement is apparently a mistake, and should refer to the presternite.
Pereira et al. (1994:165) say of the internal edge of the forcipular tarsungulum of I. perrieri: “with ca. 6 well developed teeth, fig. 29”, but the number 6 was an involuntary mistake, because it refers to the lectotype male of the species which has 5 teeth (Fig. 60).
Pereira & Minelli (1996:110) adding data on I. perrieri state “ lectotype female”, but this was in error: this specimen is a male, as correctly stated when it was designated as the lectotype of the species by Pereira et al. (1994:166, 167).
Besides the type locality, Foddai et al. (2000:155) also give for the geographical distribution of I. perrieri “ Peru: Atiquipa bei Chala”. But this latter locality corresponds in reality to I. krausi Pereira & Minelli, 1997 which was described on the basis of a single specimen from that locality (erroneously identified by Kraus (1957) as I. perrieri).
Type locality: Brazil: Haut Carsévène. Distribution: Only known from the type locality.
