03F91146D877AB5BFEA1F92FC5CDE510.taxon	materials_examined	Type species. Stenozonium exile Shelley, 1998, by original designation. Diagnosis. As presented by Shelley (1998). Components. Three allopatric species are known; others may exist in moist coastal environments north of San Francisco Bay. Distribution. Occupying widely segregated areas in the Coast Range of northern California, central Oregon, and the Olympic Peninsula of Washington; the Oregon species also ranges eastward onto the western slope of the Cascades (Fig. 2). Remarks. While additional species of Stenozonium may yet be encountered and the ranges of the known ones will surely expand with additional samples, the lacunae between the three components will surely never be completely filled because of their sizes (180 & 235 mi (288 & 376 km )). We therefore suspect that Stenozonium truly consists of allopatric species, in contrast to the continuous distributions of species and populations in the other Pacific polyzoniid genera, excepting the Monterey County, California, population of Bdellozonium cerviculatum, and in contrast to the continuous pattern in the Pacific species of Octoglena (Shelley 1995, 1998). Allopatry patterns are indicators of age, evidence that a taxon has existed long enough for extinctions to generate anatomical and geographical discontinuities and isolate populations and species from each other. That Stenozonium alone among west­Nearctic polyzoniidan genera exhibits allopatry suggests greater age and that it antedates the other genera. We cannot hypothesize time periods, but the geographic evidence suggests that Stenozonium is a product of an early dichotomy in the Polyzoniidae and that both Bdellozonium and Buzonium / Buzoniini are comparatively " young " taxa.	en	Shelley, Rowland M., Shear, William A.

03F91146D876AB5EFEA1FB02C16FE4F8.taxon	materials_examined	Type specimens. ♂ holotype and juvenile paratype (North Carolina State Museum of Natural Sciences [NCSM]) collected by W. P. Leonard and C. Richart, 5 March 2005, along Queets River Rd. ca. 6 mi (9.6 km) NE jct. US hwy. 101, in Olympic National Park, Jefferson County, Washington (N 47 º 34.330 ', W 124 º 08.206 '). One ♂ and one ♀ paratypes (Field Museum of Natural History) and another ♀ paratype (NCSM) taken by same collectors on 13 February 2005 on Queets River Rd. ca. 5.8 mi (9.3 km) NE jct. US hwy. 101 (N 47 ° 39.34 ', W 124 ° 8.16 '). These sites are in the southwestern corner of Jefferson County approximately 9.2 mi (14.7 km) ENE of the town of Queets. Etymology. We are pleased to name this species for our colleague Bill Leonard, who has, by his assiduous collecting, more than doubled the number of milliped species known from the state of Washington. Diagnosis. Ocelli 3 or 4 pairs; sternum of anterior gonopods elevated in midline, with two short lobes; anterior gonopod coxa without sclerotized flap, with flattened, medial extension; ultimate podomere complex, hirsute basally and narrowly rounded apically, with spiniform projections and a trapezoidal prolongation on anterior surface, and a quadrate flange on caudal margin. Color in life (Fig. 3). Dorsum generally light yellowish with mottled brownish patterns, tergites becoming progressively fainter and more indistinct caudad; collum and succeeding 3 – 4 tergites with strongest mottling but depigmented, without yellowish base color; venter pale. Description. Body form normal for genus, long, narrow, and tapering at both ends, more strongly so on anterior end; dimensions of available specimens as follows: Holotype (36 segments including epiproct), 7.4 mm long (L), 1.4 mm wide (W), W / L ratio 18.9 %; ♂ paratype (33 segs.), 6.0 mm L, 1.0 mm W, W / L ratio 16.7 %; ♀ paratype (38 segs.), 9.5 mm L, 1.6 mm (W), W / L 16.8 %; ♀ paratype (48 segs.), 15.8 mm L, 1.9 mm W, W / L 12.0 %; juvenile paratype (29 segs,), 3.8 mm L, 0.9 mm W, W / L 23.7 %. Head subpyriform, smoothly continuing anterior tapering, labrum narrowly rounded. Ocelli darkly pigmented, either 3 pairs arranged linearly in slanted rows or 4 pairs with second ocellus (counting caudad from interantennal region) displaced slightly laterad. Antennae extending backwards to anterior margin of 5 th tergite, composed of seven articles, 2 – 5 clavate, relative lengths of antennomeres 6> 5> 3> 4> 2> 1> 7. Midbody tergites normal for genus, with faint ozopores at caudolateral corners; epiproct rounded, protruding slightly caudad. Opposing legs separated by relatively broad sterna, legs extending laterad and terminating short of lateral segmental margins, invisible in dorsal perspective. Sternum of anterior gonopods (Figs. 4 – 5) elevated in midline and expanding into two short, subquadrate lobes. Anterior gonopod coxa with flattened medial extension, podomeres 2 – 4 with narrow, elongate, medial lobes; ultimate podomere elongate and complex, directed anteriad, hirsute basally and glabrous thereafter, hirsute basal part terminating in rounded shoulder proximal to quadrate flange on caudal surface, with three slender, spiniform projections on anterior margin opposite flange, middle one longest, podomere curving slightly laterad distally with narrowly rounded tip overhanging shallowly bifurcate, trapezoidal prolongation on anterior margin distal to spines. Posterior gonopod sternum (Fig. 6) broad, expanding slightly laterad, ultimate gonopodal podomere strongly falcate with suggestion of subapical barbs (difficult to discern clearly even at 400 x). Ecology. The specimens were encountered in winter in leaf litter and under woody debris and rocks in second­growth rainforest approximately 40 m south of the Queets River. The canopy was nearly closed and dominated by western hemlock (Tsuga heterophyla), western red­cedar (Thuja plicata), red alder (Alnus rubra), and sword fern (Polystichum munitum). Mr. Leonard's diplopod discoveries have generally come in winter or early spring (Shelley, 2003 b; Shear & Leonard 2003, 2004), a time that past collectors avoided because of the inevitable cold, damp weather. Consequently, he has unearthed an entirely unknown fauna in this part of the continent. Distribution. Known only from the type locality, which is approximately 180 mi (288 km) north of S. benedictae Shelley in Lincoln County, Oregon, and 90 mi (144 km) north of the Columbia River. Remarks. Stenozonium leonardi exhibits the light yellowish coloration and long narrow body form of the congeneric species in Oregon and California, so these features truly diagnose the genus. However, the absence of the base color on the anteriormost segments in S. leonardi, photographed alive in fig. 2, is striking, and these segments also exhibit the heaviest mottling. Whether this depigmentation exists in S. exile and benedictae is unknown, as all the available material had been preserved in alcohol for at least 21 years when Shelley (1998) described them. The W / L ratio drops noticeably with age, as the millipeds add segments and grow longer but do not become proportionally broader.	en	Shelley, Rowland M., Shear, William A.
