Dolichoderus dibolia, new species 
(Fig. 1) 
Diagnosis {worker). Similar to the living species D. attelaboides 
and D. imhecillus, particularly in its attenuated occipital “neck” and 
overall body shape (including especially the alitrunk and propodeal 
spines) but differs from both forms in its somewhat larger size; 
proportionately thicker mesothorax; lower, more rounded petiolar 
node (quadrate in side view in the case of attelaboides and imbecil- 
lus ), and much longer anterior petiolar peduncle. 
The name dibolia, Greek for lance, refers to the strongly devel- 
oped propodeal spines. 
Holotype worker. Length of alitrunk 3.7 mm. With moderately 
abundant, coarse, erect hairs, especially on the antennal scape. 
Sculpturing not determinable due to the obscuring of much of the 
body surface. 
The genus Monads may eventually be fused with other blocks of 
the Dolichoderini (see Brown, 1973, who synonymizes it under 
Dolichoderus ), but until a thoroughgoing revision of the tribe is 
completed I regard it as both prudent and convenient to treat this 
genus as a separate entity. For the moment all the New World 
species placed in Monads (Kempf, 1959) are distinguished by their 
possession of angulate or spiny pronotal humeri and laterally mar- 
Monacis
