Type species

Aptyctosmilax helenae gen. et sp. nov.

Other included species

None.

Diagnosis

Differs from other genera of Prionopetalini by the combination of a moderately extended torsotope, a post-torsal spine, a long taeniate telomere forming a full (> 180°) coil, a slender solenomere as long as

the telomere and coiling with it, a long slender spine associated with the solenomere, and a strongly striated limbus partially divided into shallow lobes.

Etymology

The genus name (gender feminine) is an anagram of Calyptomastix and refers to the similarities between the two genera.

Remarks

In the key to genera of “ Odontopyginae ” of Kraus (1966), the new genus runs to Patinatiopsis , but differs in having a post-torsal spine and a much less compact telomere. If the other alternative of the limbus character in couplet 7 of this key is chosen, the new genus runs all the way through the remaining key to Odontopyge , cf. Enghoff (2016a). The extended torsotope is shared with Calyptomastix Hoffman & Howell, 2012 , but in the latter genus, the torsotope extension is more pronounced, and the solenomere is completely hidden with a compact telomere. Many characters, including the structure of the limbus, are also shared with Antipustia gen. nov., but in the latter genus, the gonopod coxa is strongly angled and has a stout lateral spine, the telomere is much shorter and does not form a full coil, and there is no long basal solenomeral spine (although the short, stout basal telomeral spine may be its homologue).
