( Figs 23–28 , 29 )

Etymology. The specific epithets is derived from the name of locus typicus of the species—Ilakaka, a small town in Ihorombe Region in the south western part of Madagascar.

Diagnosis. The species differs from Kelyflata capensis by the following characters of male terminalia: anal tube club-like (anal tube elongate end ensiform in K. capensis ); genital style ovoid (genital style triangular in K. capensis ); periandrium stout, with rounded apex (periandrium elongate, tapering apicad in K. capensis ); dorsal part of periandrium with median lobe long and narrow (dorsal part of periandrium with median lobe short, club-like in K. capensis ); aedeagus with 2 long processes placed in apical part (aedeagus with 1short process placed medially in K. capensis ).

Description. Measurements. Total length— 6.25 mm. Vertex: ratio A/B = 25.00 Frons: ratio C/E = 0.93; D/E = 1.11. Pronotum: ratio F/B = 11.00. Mesonotum: ratio G/F = 4.36; G/B+F = 4.00; G/H = 0.87. Tegmina: I/J = 4.25; I/K = 2.50.

MALE TERMINALIA. Anal tube, in dorsal view, club-like ( Fig. 24 ). Pygofer, in lateral view, with bluntly rounded antero-ventral angle; anterior margin shallowly concave, dorsal margin descendent and shallowly concave, posterodorsal angle sharp, posterior margin with breaking point before midlength. Genital style ovoid ( Fig. 23 ). Phallic complex. Periandrium stout, with rounded apex ( Fig. 25 ). Dorsal part of periandrium, in lateral view, a bit shorter than ventral part, median lobe long and narrow ( Figs 25, 27 ). Ventral part of periandrium, in dorsal view, club-like ( Fig. 27 ). Aedeagus with 2 long processes placed in apical part ( Figs 26, 28 ).

FEMALE TERMINALIA. Female unknown.

COLORATION. Similar to that of K. capensis .
