Key to the southern South American Eurhopalothrix species
1 Dorsum of head, mesosoma and metasoma entirely covered on appressed squamose setae. Small species (HW 0.38–0.45) ( Fig. 3 View FIGURE 3 )................................................. E. bruchi View in CoL (ARG; BRA: SC, PR, SP, RJ, MG, ES, BA; PAR)
- Pilosity never as above, species either mostly glabrous having conspicuous standing setae, sparsely distributed, easily countable, forming symmetrical pairs and ground pilosity never squamose. Various sizes, usually larger than above................ 2 2 Transverse arched ridge present on face.................................................................... 3
- Transverse arched ridge absent on face.................................................................... 4
3 Transverse arched ridge on clypeal region ( Fig. 4 View FIGURE 4 , A)...................................... E. clypeata View in CoL (BRA: BA)
- Transverse arched ridge on frontovertexal region ( Fig. 4 View FIGURE 4 , B).......................... E. depressa (BRA: SP, SC, RS) 4 Dorsum of head, mesosoma and metasoma devoid of standing setae ( Fig. 5 View FIGURE 5 , A)................................................................................................. E. spectabilis View in CoL (BRA: BA, MG, SP, PR, SC; PAR).
- Dorsum of head, mesosoma and metasoma having standing “pompon-like” setae ( Fig. 5 View FIGURE 5 , B)......................... 5 5 Infradental propodeal lamella expanded at least in its upper portion ( Fig. 6 View FIGURE 6 , A).................................... 6
- Infradental propodeal lamella small and adjunct to the curvature of the propodeal descending surface ( Fig. 6 View FIGURE 6 , B).......... 7
6 Projecting setae on anterior margin of scape considerably different from those on its dorsal surface. Infradental lamella expanded across its entire length. Large species (HW 0.96)..................................... E. lenkoi View in CoL (BRA: BA, ES, SP)
- Scape without differentiated setae on its anterior margin when compared to those on its dorsal surface. Infradental lamella becomes thin on its lowermost level ( Fig. 6 View FIGURE 6 , A). Small species (HW 0.53–0.58)........ E. pilulifera View in CoL (BOL; BRA: BA, GO)
7 Dorsum of head with three pairs of standing setae; promesonotum with two pairs (both at the mesonotal level). Eye large, easily larger than diameter of tip of pompon-like seta as seen from above ( Fig. 7 View FIGURE 7 , A)......... E. speciosa View in CoL (BRA: MG, RJ, SP, SC)
- Dorsum of head with nine pairs of standing setae; promesonotum with four pairs (two at the pronotum level and two at the mesonotum level). Eye small, not much larger than diameter of tip of pompon-like seta as seen from above ( Fig. 7 View FIGURE 7 , B)......................................................................... E. reichenspergeri (BRA; MG, SP, SC)
With the revival of E. reichenspergeri , registers of E. gravis View in CoL from southern South America which were not studied, such as that of Silva & Brandão (2014), might in fact represent E. reichenspergeri populations. Only two Eurhopalothrix species, E. clypeata View in CoL and E. pilulifera View in CoL , remain occurring both in the southern and in the northern portions of South America ( Fig. 8 View FIGURE 8 ).
