DIAGNOSIS. FEMALE. T2 basally without setal spots. Pygidial area long triangular. MALE. Unknown.

DESCRIPTION. FEMALE. Body length 4.4-7.2 mm. Head black, except antennal tubercle, clypeus and mandible partly reddish brown. Mesosoma and coxae ferruginous, remainder of legs brownish. Metasoma black, except T1 basally brownishred and S1 ferruginous. Body setae generally sparse and silvery, except frons black and mesosomal dorsum with reddish setae; T2 disc, T4 and T5 setae densely black; and T1 apex, T2 apical band, T3 entire and T6 basal tuft with dense yellowish setae. Head. Width behind eye 1.1 × width of pronotum. Frons, vertex and genal punctures dense to confluent. Mandible apex bidentate. Clypeus with preapical curved carina, ending anterad with weak lateral tubercle; basomedial portion with weak tubercle. Antennal scrobe with curved lateral carina. Genal carina weak, obscured by punctures and setae. F1 2.0 × pedicel length, F2 1.6 × pedicel length. Mesosoma. Length 1.25 × maximum width. Dorsum of mesosoma with coarse confluent punctures; weak interrupted carina separating dorsal and lateral surfaces of mesonotum. Side of mesosoma smooth with short setae. Mesopleural lamella with indistinct interrupted carina. Humeral carina simple. Scutellar scale nail-like, ~3 punctures wide, surrounded by few interconnected tubercles. Posterior propodeal face reticulate, lateral and posterior propodeal faces separated by row of teeth. Metasoma. S1 with longitudinal wave lamella. T2 felt line 0.35 × total length of T2. T6 with long triangular pygidium, with lateral carina; smooth throughout.

DISTRIBUTION. Indonesia (Lombok).

ETYMOLOGY. I am pleased to name this new species in honour of Alfred Wallace, the pioneering evolutionary biologist who collected many mutillids during his exploration of the Malay Archipelago in 1854-1862. Treat as noun in apposition.

REMARKS. I place this species in the genus Krombeinidia because of the apical setal band on T2 and the shape and structure of the pygidial plate, despite the absence of basal setal spots on T2.
