Key to males of the Sphecapatodes ornata group [modified from Zhang et al. (2014)]

1. Posterior (upper) part of frontal vitta about 1.50× as broad as anterior (lower) part, frontal setae long and crossed..................................... [species formerly assigned to the genus Turkmenisca (see Rohdendorf 1975; Verves 1980)]

- Posterior part of frontal vitta about 3.0× as broad as anterior part, frontal setae fine and not crossed.................... 2

2. Proclinate orbital bristles 2, gena ground color brown, presutural acrostichal bristles 1 or 2, dorsocentrals 2 + 3, fore first tarsomere with sparse setulae on the anteroventral surface........................................................ 3

- Proclinate orbital setae four (two strong), gena ground color dark red, presutural acrostichal setae absent, dorsocentrals 3 + 4, fore first tarsomere with dense setulae on the anteroventral surface.............................. S. ornata Villeneuve

3. Fore first tarsomere with more than one or dense basal setulae, parafacial plate with more than ten setulae, black spots or vitta on the abdomen distinctly separate. WIP with a well-defined band along the posterior margin........................ 4

- Fore first tarsomere with one elongated ventral seta, parafacial plate with about ten setulae, the black spots on tergites 1 to 4 almost fused together. WIP with only a single, rather ill-defined magenta band along the posterior margin ( Fig. 30D ). Surstylus with tip curving posteriorly, phallus apically slightly broadened in lateral view ( Fig. 28D )............................................................................................. S. xuei Zhang, Chu, Pape & Zhang 2014

4. Fore first tarsomere with dense basal setulae. WIP with magenta spot on the apical part ( Figs 30E, F ).................. 5

- Fore first tarsomere with four elongated ventral setulae. WIP ( Fig. 30A ) with a clearly demarcated green band between an inner magenta band and an outer blue/magenta band ( Fig. 30A ). Surstylus with apex straight (not curving posteriorly), phallus apically narrower in lateral view ( Fig. 28C )....................................... S. kaszabi Rohdendorf & Verves

5. The fore second tarsomere about 0.60× as long as the fore tarsomere, the fore first tarsomere straight; fore tarsus with basal dense setulae on the ventral surface. WIP with a clearly demarcated green band between an inner magenta band and an outer blue band, with a narrow yellow band along posterior wing margin, and with a magenta spot on the apical part ( Fig. 30E ). Distiphallus distinctly swollen, with a constriction before the membranous tip................... S. superciliosa sp. nov.

- The fore first tarsomere curved and with dense ventrobasal setulae curving downwards, the tip is bent forward, the length of second fore tarsomere equal or subequal to the fore tarsomere; syntergite 1 + 2 with one inverted mountain-like vitta. WIP with a broad yellow band along posterior wing margin and with a broad magenta spot on the apical part ( Fig. 30F )............................................................................................ S. xinjiangensis sp. nov.
