Additional material examined.

MADAGASCAR: Antsiranana Province [Sava Region]: 10 ♂, 8 ♀, 15 nymphs (CAS 9072435 [BLF9556]), Foret de Binara , 13°15′18″S 49°37′00″E, 1 December 2003, B.L. Fisher ; 1 ♂, 6 ♀, 8 nymphs (CAS 9072455 [BLF9872]), Foret de Bekaraoka , 13°10′00″S 49°42′36″E, 7 December 2003, B.L. Fisher .

Diagnosis.

Very similar to A. lorenzorum sp. nov. but has the largest female body size of Antsirananaella gen. nov. (e.g., body length 2.47 (♀) versus 2.17 (♀) in A. faulstichi sp. nov., 2.21 (♀) in A. marlae sp. nov., 2.33 (♀) in A. lorenzorum sp. nov.; carapace length 0.77 (♀) versus 0.65 (♀) in A. faulstichi sp. nov., 0.70 (♀) in A. lorenzorum sp. nov., 0.71 (♀) in A. marlae sp. nov.); most slender chelal hand of females in Antsirananaella gen. nov. (0.85 (♀) × longer than wide versus 0.71-0.81 in other species of Antsirananaella gen. nov.). Difference in trichobothrial pattern: sb on the same sagittal level as est (more distal in A. lorenzorum sp. nov. and A. faulstichi sp. nov.); it between eb and et equidistant to both of them (closer to eb than to et in all other species of Antsirananaella gen. nov.); et midway between dt and eb on fixed finger (in the distal third between them in A. marlae sp. nov. and A. faulstichi sp. nov.).

Etymology.

This species is a patronym for DH’s beloved daughter.
