Subgenus Teloganodes Eaton 1882

( Figs 1–12 , 20–105 )

Genus Macafertiella Wang in Wang & McCafferty 1996: 15. Type species M. insignis Wang & McCafferty 1996 .

Part of genus Teloganodes: Sartori, Peters & Hubbard 2008: 9 .

Subgenus Teloganodes: Kluge 2023 .

Type species: Cloe tristis Hagen 1858 .

Diagnosis. Tergalii II–VI (5 pairs) present; tergalii III–V with ventral lobe and with cleft on dorsal lobe; tergalius VI normally without ventral lobe and without cleft on dorsal lobe ( Figs 1–5, 7–12 ); individual tergalius can bear vestigial ventral lobe ( Fig. 6 ). Differs from all other subgenera by retention of tergalii VI.

Indian representatives. Three species, Teloganodes (Teloganodes) dentatus Navás 1932 , T. (T.) kodai Sartori in Sartori et al. 2008 and a new species, T. (T.) velutinus sp. n.
