Rm. Shelley, THE MILLIPEDE ORDER CALLIPODIDA IN WESTERN NORTH-AMERICA (SCHIZOPETALIDAE, TYNOMMATINAE), AND A SUMMARY OF THE NEW-WORLD FAUNA, Entomologica Scandinavica, 27(1), 1996, pp. 25-64
In western North America, the milliped order Callipodida is represente
d by the Colactidini, Tynommatini stat. n., and Diactidini tribus n.,
in the subfamily Tynommatinae, family Schizopetalidae; a coordinate tr
ibe, the Texophonini, occurs on the Gulf Coast of south Texas. The Tyn
ommatini consists of two genera and four species: Tynomma mutans (Cham
berlin), T. magnum Buckett & Gardner, and T. gardneri sp. n., occurrin
g around Monterey and San Pablo/San Francisco Bays, California, and Id
rionaria dineh gen. n. & sp. n., in Washington County, Utah. The Colac
tidini ranges from Durango, Mexico, to central Utah and California eas
t of the Sierra Nevada, with disjunct areas in southern California and
Baja California, the latter extending northward to metropolitan San D
iego. It is represented by two genera and 6 species: Colactis Loomis:
C. tiburona (Chamberlin), utorum (Chamberlin), and protenta and quadra
ta, both by Loomis; and Heptium Loomis: H. carinellum and scamillatum,
both by Loomis. The Diactidini, occupying coastal southern California
and the adjacent fringe of Baja California, is comprised of three gen
era and 10 species: Diactis Loomis: D. soleata, triangula, and frondif
era, all by Loomis, and amniscela, cupola, jacinto, procera, and strum
ella, all spp. n.; Florea sinuata gen. n. & sp. n.; and Caliactis bist
olata gen. n. & sp. n. The following new synonymies are proposed: C. y
uma Chamberlin, sideralis Loomis, and loomisi Hoffman under C. tiburon
a; C. briggsi Shear and saxetana and baboquivari, both by Loomis, unde
r C. utorum; H. canum Chamberlin under H. carinellum; and Etiron paroi
cum and pearcei, both by Chamberlin, under D. triangula and T. mutans,
respectively. The eastern Nearctic callipodid fauna is summarized and
significant new localities are reported; Tetracion antraeum Hoffman,
stat. n., is elevated from a subspecies of T. jonesi Hoffman.
