Family Tingupidae Loomis, 1966

Tingupidae Loomis, 1966:227 . Shear, 1969:140; 1972:264; 1981:5­6. Loomis & Schmitt, 1971:128. Peck & Lewis, 1977:49. Hoffman, 1980:135; 1999:253. Kevan, 1983:2967. Gardner, 1986:34. Shear & Hubbard, 1998:86 ­88. Shelley et al., 2000:79.

Diagnosis. Chordeumatida with two pairs of setose angiocoxites on the gonopods; 9th legs reduced to one, two, or three podomeres, coxae without prominate coxites; 10th and 11th legs with coxal glands.

Components. Tingupa Chamberlin, 1910 ; Buotus Chamberlin, 1940 ; Blancosoma Shear & Hubbard, 1998 .

Distribution. The Alaskan Panhandle; the Queen Charlotte Islands (QCI), BC, Canada; coastal Oregon; the Sierra Nevada of central California; northern Idaho and western Montana; northwestern Colorado; northern, southwestern, and southeastern Utah; southeastern Arizona; southwestern Illinois to northern Arkansas; and eastern West Virginia to northcentral North Carolina ( Fig. 4 ) ( Chamberlin 1910, 1925, 1928, 1940; Chamberlin & Hoffman 1958; Loomis & Schmitt 1971; Shear 1972, 1981, map 1; Shear & Hubbard 1998; Hoffman 1999). Southeastern Utah is based on the obscure record of two females from Devil's Canyon, San Juan County ( Chamberlin 1928) that has been missed by previous authors; its generic and specific identities are unknown.

Remarks. Tingupidae , an endemic North American milliped family, was revised by Shear (1981). He and Hoffman (1980) recognized two genera, Tingupa and Buotus , the latter being monotypic and transferred into the family by Shelley (1976) after being misplaced in the order Polyzoniida , family Polyzoniidae ( Chamberlin 1940; Chamberlin & Hoffman 1958). Shear and Hubbard (1998) added a second monotypic genus, Blancosoma , and provided a key to the three component genera. Tingupidae is closely related to the monotypic family, Niponiosomatidae Verhoeff, 1941 , in Japan, and the two belong to the superfamily Brannerioidea Cook, 1896, suborder Craspedosomatidea Brolemann, 1935, along with eight other families ( Shear 2000; Shelley 2003). Shear (1988) maintained both Tingupidae and Niponiosomatidae primarily because of somatic apomorphies of Tingupa (paranota and tergal microsculpture), even though the gonopod structure of Niponiosoma Verhoeff, 1941 , is closer to that of Tingupa than those of either Buotus or Blancosoma . However, Blancosoma does not possess these somatic features and thus resembles Niponiosoma . Niponiosomatidae holds taxonomic priority over the more widespread and utilized Tingupidae , so synonymization would have the undesirable consequence of submerging this continental North American taxon under the geographically restricted and little­used Japanese name.
