( Figs 13–16 , 106–136 )

Genus Dudgeodes + part of genus Teloganodes: Sartori in Sartori, Peters & Hubbard 2008: 25 .

Subgenus Dudgeodes: Kluge 2023 .

Type species: Dudgeodes pescadori Sartori in Sartori, Peters & Hubbard 2008.

Diagnosis. Tergalii II–V (4 pairs) present; tergalii III–IV with ventral lobe and with cleft on dorsal lobe; tergalius V without ventral lobe, either with cleft on dorsal lobe ( Fig. 16 ), or without it ( Kluge 2023: figs 59–60); tergalius VI absent. Differs from Teloganodes by loss of tergalii VI; differs from Derlethina by retention of tergalii V.

Indian representatives. Two species, among which Teloganodes (Dudgeodes) palnius (Selvakumar et al. in Selvakumar et al. 2014) is distributed in Southern India, and T. (D.) selvakumari (Martynov & Palatov in Martynov et al. 2022) is described from the Indian Himalayas.
