 Nylander's (1856b)
description of opaca is at  ; he recognises opaca
as described in manuscript by Dufour and from Savignyi, Atl. Aegyt,
X, 20, f.7. Roger's (1862b) description of the queen and male is at  ;
Emery's (1916b key) description including the worker is at  ; Leach, W. E. 1825. Descriptions of
thirteen species of Formica and three species of Culex,
found in the environs of Nice. Zool. J. 2, 289-293 [HNS
unavailable]. Santschi's (1931a) descriptions of cruentior and lindbergi
are at  ; he attributes the
species to Olivier (presumably Olivier, 1792) but this appears to be an
error.

 Cagniant
(1985b) studied a range of populations and describes cruentatus
as polymorphic, with a considerable size range, TL 6-14 mm;
His general description of the worker was - colour head, scape and
promesonotum blueish-black, scape, propodeum, petiole and base of legs
reddish brown, rest of legs very dark brown, funiculus clearer,
posterior gaster black.
Leach (1825) had head and alitrunk evenly dark, base of scapes fuscous;
gaster segments with the bases reddish; base of femora intensely red,
tibiae fuscous. Latreille noted the petiole scale was brown with fawn
hairs.
