183 
dorsally; distitarsi without ventral spines; claws toothed. Metasoma 
with first segment of typical agenioid form in dorsal view, sides 
concave, expanded at insertion on mesosoma, in lateral view 
without a suture separating an epipleurum; second sternum with 
transverse suture in extreme anterior position, connate medially 
with posterior margin of first sternum; pygidial area undifferen- 
tiated, dull, densely clothed with long, uniformly fine setae. 
Male. Similar to female in most details, but head with clypeus 
and occipital carina unmodified; apex of labrum exposed in frontal 
view; mandibles slender, bidentate; anterior tibial spur barely 
exceeding apex of tibia; anterior and middle legs with distitarsi 
longer than preceding three segments taken together. Metasoma 
with first sternum convex; second sternum swollen anteriorly, swell- 
ing bordered posteriorly by curved, deeply impressed transverse 
groove; apical margin of sixth sternum (fig. 3) with large, rectangu- 
lar emargination and paired apical spines; genitalia (fig. 4) with 
aedeagus bearing pair of accessory apodemes; basal hooklets single. 
Type species. Atopagenia menkei Wasbauer, new species. 
Etymology. Gr.: Atopos — odd or strange; agenia — beardless. 
Atopagenia menkei Wasbauer, new species. 
Holotype female. Black with faint blue to violet reflections 
imparted by appressed pubescence; small spots under compound 
eyes, apex of clypeus and apex of mandibles, ferrugineous. Length 
29 mm. Anterior wing length 31 mm; both pairs uniformly dark to 
apex with strong violaceous reflections. Erect hair black, long, fine 
and abundant over most of body, absent on following areas: 
mesonotum, except for a few scattered hairs anteriorly, femora dor- 
sally, anterior and middle tibiae and tarsi, the latter with a few short 
hairs dorsally, first metasomal tergum except at apex. Appressed 
pubescence dense, fine and dark on head and mesosoma, imparting a 
dull, velvety appearance, more dilute on somewhat shining meta- 
soma. Head (fig. 1) rounded, about as wide as long, FD/TFD 1.05; 
ocelli forming a compact right triangle, laterals much closer to each 
other than to compound eyes, POL/OOL 0.57; front moderately 
narrow, MID/TFD 0.56; compound eyes nearly parallel, LID/UID 
0.95; length of clypeus 0.59 times its width, apical margin strongly 
convex; length of malar space 0.56 width of mandible at base; 
antennae very long, slender, third segment 10.8 times as long as
