GENUS NEOKAPALA Girault. 
1. NEOKAPALA FURCATELLA Girault. Female. Genotype. 
Length, 3.25 mm. 
Dark metallic green, the propodeum, abdomen and head blue; legs fuscous, the 
antenne black with brownish club and scape, 11-jointed, no ring-joint. Fore wings infuscated 
distad of the distal end of the marginal vein (more proximad at caudal margin), the infusca- 
tion accented under the end of the marginal vein. Scutellum produced into a prong like the 
two arms of a tuning-fork, each prong about as long as the scutellum, brownish toward tip, 
flattened, the edges carinated; scutellum longitudinally striate. Head shining, thorax umbili- 
cately punctate. Abdominal petiole not as long as the arms of the scutellar process. 
Antenne with the funicle joints produced from one side at apex, flattened, the club solid, 
ovate, the pedicel small and cup-shaped, funicle joints 2 and 5 longest, subequal, the first 
funicle joint longer than the pedicel by far but cylindrical oval, not produced. 
Habitat: Cairns, Queensland. 
Type: No. I. 1278, South Australian Museum, Adelaide. 
This genus differs from Kapala Cameron by the scutellar processes which are short, 
blunt at end and forming a prong which is high up over the base of the abdomen.
