Occam's razor

It is desirable for each taxonomist to follow the rule of Occam's razor: "Entities are not to be multiplied without necessity" (Non sunt multiplicanda entia sine necessitate). The purpose of Taxonomy-science is to understand and restore order, and not to describe as many new species as possible.

Two new species of Pterostichus Bonelli subgenus Pseudoferonina Ball (Coleoptera, Carabidae, Pterost

Abstract
Two new species of Pterostichus Bonelli subgenus Pseudoferonina Ball, are described from the mountains
of central Idaho: Pterostichus bousqueti Bergdahl [type locality = small tributaries of South Fork of Payette
River watershed, ca. 1170 m (3840 ft), 44.0675°/-115.6822°, near Lowman, Salmon River Mountains,
Boise County, Idaho, U.S.A.] and Pterostichus lolo Bergdahl [type locality = Cottonwood/Orogrande
Creek, ca. 870 m (2850 ft), 46.5528°/-115.5522°, North Fork of Clearwater River watershed, Clearwater
Mountains, near Bungalow, Clearwater County, Idaho, U.S.A.]. Males of P. bousqueti and P. lolo are easily
distinguished from each other and the seven previously described Pseudoferonina species by the form of the
median lobe of the aedeagus, and from most individuals of the other species of Pseudoferonina in Idaho by
features of pronotal shape and macrosculpture. Both species appear to be obligate ripicolous hygrophiles,
restricted in distribution primarily to the margins of small montane streams in forested areas. Widespread
intensive stream surveys for Pseudoferonina over many years indicate the geographic ranges of both species
are highly localized, and additional undescribed species may occur in Idaho.
