Morphological Studies 
Comparison of the type material of E. kraussei, E. vandeli, and E. 
foreli with new material 
The types of E.v. and E.f are deposited in the Naturhistorisches 
Museum Basel, Switzerland. We could study 1$ E. foreli, and 1? E. 
vandeli, both from the type series. The Museo Civico di Storia 
Naturale “Giacomo Doria” in Genova, Italy, has provided us with 
the types (1$, lj) of E. kraussei. 
With a close examination of these types we could only confirm 
the similarity of all 3 “species” as was already stated by Kutter 
(1973). We therefore refrain from a detailed presentation of mea- 
surements and structures compared. We also did not find any con- 
stant differences between the types and specimens from our newly 
collected material, with respect to size, shape of petioli, head and 
thorax, length of body hairs etc.; just the coloration was slightly 
variable between different populations. Thus, the population from 
Calabria (E. foreli), and one from Spain (pop. no. 3) exhibit a quite 
light, yellowish brown coloration of $ and $. Other E.k. popula- 
tions appear brownish, whereas a dark brown or nearly black is 
typical for 9 E. vandeli (pop. no. 5), for a colony from La Couronne 
(no. 6), and for population no. 9 from Corsica. Young 9 9 are 
darker in coloration than old queens, and callow 9 2 usually exhibit 
some darker spots in the thorax, and a yellow base of the gaster,
