Rd. Price et Ra. Hellenthal, TAXONOMIC IMPORTANCE OF FIRST-INSTAR CHEWING LICE (PHTHIRAPTERA, TRICHODECTIDAE) FROM POCKET GOPHERS (RODENTIA, GEOMYIDAE), Annals of the Entomological Society of America, 89(4), 1996, pp. 510-518
A study of 1st-instar nymphs representing 119 of the 122 currently rec
ognized taxa of pocket gopher lice of the genera Geomydoecus and Thomo
mydoecus resulted in the recognition of numerous valuable taxonomic fe
atures enabling reliable differentiation for a surprisingly large numb
er of these lice. These characters are discussed primarily at the spec
ies complex level, with mention of specific differences where pertinen
t. A key is given for the identification of the currently recognized 2
6 complexes of pocket gopher lice.
