03E7878FFFD39664D3B0FA5FFB55FE82.taxon	diagnosis	Diagnosis. A genus of Striariinae composed of a single species, distinct from other small striariids in having a single ommatidium on each side of the head (om, Fig. 2), a notch in the collum at the position of the outermost metazonital seta (cn, Fig. 2), absence of coxal flasks on the third legs (L 3, Fig. 6), characteristically modified coxae of the fifth legs (Fig. 7) and the telopodites of the ninth legs enveloping the gonopods at rest (Fig. 9). None of these characters are found in previously described genera of striariids.	en	Shear, William A., Marek, Paul E., Bond, Jason E., Wesener, Thomas (2022): The millipede family Striariidae Bollman, 1893.

03E7878FFFD39664D3B0FA5FFB55FE82.taxon	discussion	Notes. This genus is part of a complex of genera yet to be described that includes very small species (<5 mm long) with subequal crests, distributed from northern California to the Puget Sound region of Washington, but is a geographic outlier found in northern Idaho. The biogeographic connections between northern Idaho and the Cascade and Coast Ranges further west, despite the intervening arid Snake River Plain, are well known and extend to both floristic and faunistic evidence (Brunsfeld et al. 2011; Richart & Hedin 2013; Shelley 1990).	en	Shear, William A., Marek, Paul E., Bond, Jason E., Wesener, Thomas (2022): The millipede family Striariidae Bollman, 1893.

03E7878FFFD09665D3B0F99EFB6CFBD2.taxon	description	Description. Based on male holotype from Beauty Creek. Length, 3.8 mm, greatest width 0.56 mm. Twentyeight rings (collum + 26 leg-bearing rings + telson). Head (Figs 1, 2, 5) densely setose, with single ommatidium (om, Fig. 2) on each side. Lateral corners of labrum (lab, Fig. 5) rounded. Mandibular stipes (m, Fig. 5) with distal, short, acute process. Collum (col, Fig. 1) with distinct anterior rim, notched at position of lateralmost segmental seta (cn, Fig. 2), crests short, limited to posterior fourth of collum, sixth crest marginal. Subsequent rings (Figs 1, 3) with crests extending full length of metazonite, subequal in height. Metazonital setae long, with brush-like tips. Telson (tel, Fig. 4) short, lacking crests, lateral lobes suppressed but middle lobe obvious. Spinnerets directed posterioventrad. Paraprocts (pp, Fig. 4) with three setae, ornamented with elongate tubercles. Hypoproct (hp, Fig. 4) with two setae, similar tubercles. First leg pair (L 1, Fig. 5) encrassate, without needle-like setae, few flattened, twisted setae on distal podomeres. Second leg pair (L 2, Fig. 1) reduced, femora clavate. Leg pairs 3 – 7 strongly encrassate, third leg pair (L 3, Fig. 6) lacking coxal flasks; fourth leg pair (L 4, Fig. 6) the largest, coxae slightly excavated anteriorly; coxae of fifth leg pair (L 5, Fig. 6) enlarged, with blunt anterior lobes set with acute tubercles (Fig. 7); sixth and seventh leg pair coxae unmodified. Proximal segments of all legs ornamented with typical flattened setae (Fig. 8). Gonopods (Figs 9, 10, 12, 13) with broad sternum (s, Fig. 9) bearing lobes extending laterally. Coxae (cx, Figs 9, 13) with 3 – 5 setae, long coxal process (cxp, Figs 10, 12, 13) parallels anterior angiocoxites (aac, 9, 10, 12, 13). Posterior angiocoxae (pac?, Fig. 12) sheaths single, large flagellocoxite (fc, Figs 12, 13). Colpocoxite (cc, Figs 10, 12, 13) as elongate, fimbriate, weakly sclerotized branch. Tips of gonopod elements insert into cavities in ninth leg pair telopodites (see Fig. 9). Ninth leg pair (Figs 11, 14) with weak, narrow sternum, coxae and telopodites appearing fused; coxal part with mesal group of acute setae, telopodite portion laterally heavily tuberculate, with setae somewhat ensiform, mesally a large, smooth lobe envelopes tips of gonopods. Tenth coxae unmodified, with gland openings. Female paratype similar to male but lacking secondary sexual modifications, 4.2 mm long.	en	Shear, William A., Marek, Paul E., Bond, Jason E., Wesener, Thomas (2022): The millipede family Striariidae Bollman, 1893.
