Duvaliopsis pilosellus: Jeannel 1928: p. 110, figs. 1354, 1346, and 1347. 
Anophthalmus Bielzi Stobieckii Csiki: 1907: p. 574. 
Trechus (Duvalius) Bielzi Stobieckii: Knirsch 1925: p. 91. 
Duvaliopsis pilosellus Stobieckii: Jeannel 1928: p. 111. 
Jeannel’s key to species ( Monographic , III, p. 108) is erroneous 
because bielzi is said to have angular humeri with the prehumeral 
border perpendicular to the median line. However, only in pilosellus 
are the humeri sharply angular and the prehumeral borders perpendicu- 
lar. This is amply confirmed by Knirsch’s long series of both pilosellus 
and stobieckii. I can find no taxonomically significant differences be- 
tween these two supposed subspecies. The male genitalia are identical. 
Pseudanophthalmus rybinskii (Knirsch) new combination 
Trechus (Duvalius) Bielzi Rybinskii Knirsch 1924: p. 63; figs. 5 and 6; 
Knirsch 1925 : p. 91. 
Duvaliopsis pilosellus Rybinskii: Jeannel 1928: p. 111. 
P seudanophthalmus calimanensis (Knirsch) new combination 
Trechus (Duvalius) Bielzi calimanensis Knirsch 1924: p. 65, figs. 4 and 7. 
Duvaliopsis pilosellus calimanensis : Jeannel 1928: p. Ill, fig. 1353. 
These two species, P. rybinskii and P . calimanensis , are quite distinct 
from pilosellus in characters given in the key as well as in genitalic 
differences. Judging from strictly morphological criteria, they are 
probably more closely related to meliki and transylvanicus than they 
are to either bielzi or pilosellus. 
P seudanophthalmus meliki (Csiki) new combination 
Anophthalmus Bielzi Meliki Csiki 1912: p. 537. 
Duvaliopsis Meliki: Jeannel 1928: p. 114, figs. 1355, 1356, and 1357. 
Trechus (Duvalius) pauperculus Knirsch 1925: p. 91. 
Duvaliopsis Meliki pauperculus : Jeannel 1928: p. 114. 
In the distinctive boot-shaped enlargement of the apex of the 
aedeagus, this species recalls a similar feature in P. valentinei Jeannel 
and P. vanburenensis Barr (Tennessee, U. S. A.). The other species 
of the bielzi group are possibly more closely related to each other than 
to P. meliki , but the transfer apparatus confirms their affinity with the 
latter species. 
Pseudanophthalmus transylvanicus (Csiki) new combination 
Anophthalmus Bielzi transylvanicus Csiki 1902: p. 52. 
Trechus (Duvalius) transylvanicus: Knirsch 1925: p. 91. 
Duvaliopsis transylvanicus : Jeannel 1928: p. 113.
