tenebrae are: the dark legs, antennae and weakly metallic thoracic 
dorsum, black T-II, striate scapal basin and smooth propodeal 
enclosures. 
Anadelphe Kimsey, new genus 
Diagnosis. Malar space without vertical sulcus; occipital carina 
complete and well-developed; scapal basin flattened and smooth; 
flagellum short and fusiform in both sexes (figs. 2, 3); male mandi- 
bles broad and flattened with 2 small apical teeth (fig. 3); pronotum 
about as long as scutum, without medial groove or pit and without 
pit before lateral lobe; scutum with well-developed parapsides and 
deep notauli; mesopleuron with omaulus and without scrobal sul- 
cus; metanotum 0.7X as long as scutellum, with elevated medial 
area without differential sculpturing or punctation (fig. 9); propo- 
deum with long dorsal surface evenly rounded to steep posterior 
declivity, laterally rounded; tarsal claws with slender medial tooth; 
hindcoxa without dorsobasal carina; both sexes fully winged; fore- 
wing (fig. 8) RS extended by evenly curved dark streak, R1 0.5X as 
long as stigma or longer, medial vein arising before cu-a; terga 
rounded laterally. 
Type: Anadelphe simplifacies Kimsey 
Etymology: An = not, Adelpha — sister (Greek, feminine). 
Discussion. Anadelphe appears to be most similar to Adelphe 
based on the unusual male mandibles, complete occipital carina, 
long ocular setulae, thickened clypeal apex, dentate tarsal claws, 
and propodeum with long dorsal surface. However, the absence of a 
pronotal carina and scrobal sulcus and no lateral propodeal angles 
immediately distinguish Anadelphe from Adelphe. In addition, 
Anadelphe differs from all the other American amisegines due to the 
long metanotum and the malar space with an obsolescent vertical 
sulcus.
