description: Smicromorpha Girault, 1913
Smicromorpha Girault 1913: 89. Type species: Smicromorpha doddi Girault, by original designation and monotypy. Smicromorphella Girault 1930: 2. Type species: Smicromorphella minera Girault, by monotypy (synonymy by Naumann
1986).
Description. Body non-metallic yellow to orange with brown or black markings. Head with eyes usually very large, in profile occupying majority of face (e.g. Fig. 1) except in S. banksi (Fig. 16), S. minera (Naumann 1986, fig. 38), and S. eudela (Fig. 32); margin of antennal scrobe deeply impressed and carinate (e.g. Fig. 4) except in S. eudela (Fig. 33); toruli at level with or above ventral margin of eyes (e.g. Fig. 24). Mandibles asymmetric, right mandible with inner rounded lobe and acute sclerotized tooth, and left mandible with inner, stout, acute tooth and outer weakly sclerotized process. Antenna with scape translucent, pedicel swollen, and flagellum much shorter than length of eye in profile, slender and somewhat fusiform, with 5 (♂)‒6(♀) flagellomeres, and mostly bearing sparse, suberect, hair-like setae; clava (terminal flagellomere) not differentiated, 1-segmented (e.g. Fig. 26) except 2-segmented in S. attenboroughi sp. nov. (Fig. 2). Mesosoma with pronotum dorsally transverse, with or without transverse carina dorsally; mesoscutum with complete but narrow and weakly impressed notauli; prepectus minute, hardly visible; propodeum rugose-punc- tate, with petiolar foramen at dorsal margin. Hind coxa quite slender, subequal in length to hind femur; hind femur greatly enlarged, most often ventral margin serrulate without an inner tooth (e.g. Fig. 10). Wings densely setose; MV short, at most as long as STV; PMV absent or reduced to a stub; STV divergent from costal margin (e.g. Fig. 11). Metasoma elongate; base of petiole with dorsal condyle providing articulation with propodeum (Figs 31, 56); body of petiole delimited anteriorly by ventrobasal and dorsobasal laminae; postpetiolar segments unsclerotized.
Hosts. Oecophylla smaragdina (Fabricius) (Hymenoptera: Formicidae) (Girault 1913; Naumann 1986; Darling 2009). African species possibly parasitizing African weaver ant species Oecophylla longinoda (Latreille) (Naumann 1986).
Distribution. Afrotropical, Australia, India, Indonesia and Vietnam (Girault 1913, 1915, 1930; Narendran 1979; Naumann 1986; Bouček 1988, Ubaidillah & Kojima, 2004; Darling 2009; Noyes 2019; R. Copeland, pers. comm.) (Fig. 62).
Key to world species. Naumann (1986) & Darling (2009).
