Leptothorax nevadensis subsp. rudis Wheeler   HNS 1917a: 508. Six syntype workers, Camp Curry, Yosemite , California [ MCZC] [Examined]. Note: original description also includes dealate queen, and cites the type locality as Tenaya Canyon, Yosemite Valley . Incorrectly synonymized under T. nevadensis   HNS by Mackay 2000: 376.

Comments. This is a distinct species that occurs sympatrically with T. nevadensis   HNS in many parts of northern and central California, without showing any sign of intergradation. T. rudis   HNS is readily distinguished from T. nevadensis   HNS by petiole shape. In T. rudis   HNS the petiole is broader in profile, with the anterior and posterodorsal faces meeting at approximately 90º, and the posterodorsal face declining gently (Fig. 10). In T. nevadensis   HNS the petiole is more slender in profile, with the anterior and posterodorsal faces forming an acute angle (Fig. 9). In addition T. rudis   HNS has coarser body sculpture and is lighter in color than T. nevadensis   HNS . T. rudis   HNS is common in mixed coniferous forests of California, up to about 1750m elevation. Colonies can be found in rotten wood, under stones, in fallen acorns, and in the leaf litter.

Bolton (1995) stated that rudis Wheeler   HNS 1917a, then combined with Leptothorax   HNS , was a primary junior homonym of rudis Mayr   HNS 1868c. Mayr’s species, a fossil taxon, was originally combined with Macromischa   HNS , however, and then later with Nothomyrmica (Wheeler   HNS 1915i), prior to Macromischa   HNS being subsumed under Leptothorax   HNS . Mayr’s rudis   HNS was never treated as a species of Leptothorax   HNS , so no homonymy arises.
