Key to species of Sphaerobelum View in CoL View at ENA (based mainly on male characters):
1. Anterior telopod with 3 telopoditomeres................................................................... 2
- Anterior telopod with 4 telopoditomeres.................................................................... 5
2. Tergites shiny, glabrous. Process of podomere 2 of posterior telopod swollen only at inner margin. Endotergum with 3–4 dense rows of short marginal bristles.................................................... S. clavigerum Verhoeff, 1924
- Tergites hairy, process of podomere 2 of posterior telopod strongly swollen apically, spherical, broader than base of podomere.................................................................................................... 3
3. Inner margin of femur extended, with teeth. Lateral margin of prefemur with a sharp projection juxtaposed to coxal process. Body coloration black. Head smooth. Process of podomere 2 of posterior telopods truncated. Operculum of vulva two-horned, both horns blunt.................................................................... S. bicorne Attems, 1938
- Inner margin of femur smooth, prefemur without a process. Body coloration dirty olive-brown; head punctured and densely hirsute......................................................................... S. hirsutum Verhoeff, 1924
4. Inner margin of femur extended, with teeth ( Figs 2D View FIGURE 2 , 5D View FIGURE 5 ). Locking carina on anal shield short......................... 6
- Inner margin of femur smooth. Locking carina on anal shield very long........................................... 7
5. Body coloration dark olive, posterior margin uniformly light brown, antennae and legs conspicuously orange ( Fig. 1A View FIGURE 1 ). Prefemur without lateral projection ( Fig. 2D View FIGURE 2 ). Apical margins of vulval operculum equally converging towards a mesal tip ( Fig. 2I View FIGURE 2 ). Tip of laterotergite 1 slightly extended, well-rounded. Male antennomere 6 thickened ( Fig. 3A View FIGURE 3 )......... S. cattiense sp. nov.
- Body coloration dark chestnut brown, posterior tergal margins black, legs dark brown, tips light brown ( Fig. 1B View FIGURE 1 ). Lateral margin of prefemur with a sharp projection juxtaposed to coxal process ( Fig. 5D View FIGURE 5 ). Apical margin of vulval operculum recessed centrally ( Fig. 5H View FIGURE 5 ). Tip of laterotergite 1 slightly extended, sharp. Male antennomere 6 axe-shaped ( Fig. 6A View FIGURE 6 ).............................................................................................. S. konkakinhense sp. nov.
6. Podomere 3 of anterior telopod distally with a lateral extension; podomere 4 of posterior telopod distally with an incurved process overlapping with process of podomere 2. Marginal setae of terga not reaching posterior margin.................................................................................................... S. separatum Attems, 1953
- Podomere 3 of anterior telopod cylindrical, without lateral extension; podomere 4 of posterior telopod without incurved pro- cess, but with 3 separate spines. Marginal setae of terga reaching the posterior margin................................................................................................... S. truncatum Wongthamwanich et al., 2012
