Diagnosis.

Male. Clypeus dorsally elevated, sloping ventrally. Mandible with sharp subapical and large inner subbasal teeth (Fig. 18 View Figures 13–18 ), ventrally deeply excised with large basal tooth (Fig. 24 View Figures 19–36 ). Scape ventral carinae divergent apically (Fig. 35 View Figures 19–36 ), densely punctate between them; F1 apical 1/3, F2 and F3 basal 1/3 whitish yellow on ventral half; F1 strongly depressed, F1 height ~0.8 × pedicel diameter (Fig. 36 View Figures 19–36 ). T3 orange (Fig. 12 View Figures 7–12 ); cuspis strongly widened on posterior 1/3 with rounded apex (Figs 64 View Figures 49–66 , 72 View Figures 67–72 ); digitus posteriorly expanded, forming triangular projection (Fig. 47 View Figures 37–48 ); paracuspis slightly tuberculate (Fig. 72 View Figures 67–72 ); penis valve weakly expanded ventrally (Figs 65 View Figures 49–66 , 66 View Figures 49–66 ). Female. Unknown.

Material examined.

2♂. Indonesia: Bali: Tabanan, Bengkel, Pura Batu Salahan , 08°23'31.8"S, 115°05'E, 682 m alt., 12.VIII.2006, K. Watanabe leg. [1♂ TUA] GoogleMaps .

Identification source.

Keyed using Mickel (1935) and compared with the original description. No differences were found between the specimen examined herein and Zavattari’s description.

Distribution.

Indonesia: Bali, Java ( Zavattari 1914; Mickel 1935; Lelej 1996b).

Remarks.

Only three mutillid species have been recorded from Bali, namely Arkaditilla nallinia , Krombeinidia griseomaculata ( André, 1898), and Mickelomyrme pusillaeformis (Hammer, 1962) ( Zavattari 1914; Lelej 2005; Okayasu 2020; current data), although Zavattari’s record of K. griseomaculata was not accepted by Lelej (2005) and Mickel (1935). Field surveys in this small island will be useful for discovery of the female of Arkaditilla .
