MADAGASCAR: Toliara Province [ Anosy Region ]: 4 ♂, 4 ♀, 9 nymphs (CAS 9071509 [BLF4984]), Parc National d’Andohahela, Forêt d’Ambohibory, 24°55′48″S 46°38′44″E, 16-20 January 2002, Fisher, Griswold et al .; 1 ♂, 1 ♀ (CAS 9071516 [BLF4815]), Parc National d’Andohahela, Foret de Manantalinjo , 24°49′1″S 46°36′36″E, 12-16 January 2002, Fisher, Griswold et al .

Diagnosis.

Differs from T. pumila sp. nov. in different cheotaxy: est on fixed finger situated between sb and t of the movable finger on sagittal level (est on same sagittal level with sb in T. pumila sp. nov.); most compact carapace of the southern feaellid members (1.27/1.23 ♂/♀ times longer than broad versus 1.31-1.37/1.31-1.39 ♂/♀).

Etymology.

This species is a patronym honoring Charles Griswold who collected many Malagasy feaellids.

Description.

The following description is based on holotype and allotype. - Carapace (Fig. 22A ): Very compact, heavily granulate, 1.20-1.31 (♂), 1.18-1.31 (♀) times longer than broad. - Pedipalps (Fig. 22C, D ): Similar trichobothrial pattern as T. pumila sp. nov. but the following difference: est on fixed finger situated between sb and t of the movable finger on sagittal level. Chelal fixed finger with 9-10 chelal teeth in the OR, 12-14 in the MR and 9-11 in the IR; movable finger with 6-8 in the OR, 7-11 in the MR and 7-8 in the IR.
