Type specimens. ɗ holotype and Ψ paratype (NCSM) collected by R. M. Shelley, 21 August 2006, in Tlingit Park, Haines, Haines Borough, Alaska; coordinates are N 59 ° 13 ’55.4”, W 135 ° 26 ’38.1”.
Diagnosis: A small depigmented species with three depigmented ocelli arranged in single row; mesal angiocoxites of gonopods with three long, attenuated, sigmoidally curved, immobile macrosetae apically, lateral angiocoxites with both long and short, hooklike immobile macrosetae distad (Fig. 1).
Holotype. Length 5.0 mm, width ca. 0.35 mm. Segments with small paranota; segmental setae clavate, longer anteriorly and posteriorly, becoming less clavate and more acuminate posteriorly. Antennae with 5 th article inflated. Gonopods (Figs. 1,2) of typical structure; lateral angiocoxites (la) basally swollen, setose, with three or four long, attenuated, immobile macrosetae anterodistad and three strong, decurved, hooklike, immobile macrosetae on posterior surfaces of apices; mesal angiocoxites (ma) narrow, projecting anteriorly, closely appressed and basally fused, bases bulbous, shafts setose with long, attenuated, gently curved, immobile macrosetae arising from anterior surfaces at about 2 / 3 lengths, apices with three attenuated, sigmoidally curved, immobile macrosetae each. Anterior division of colpocoxite divided into three processes (Fig. 3, a, b, c), posterior division poorly sclerotized, bulbous and constricted in midline, lower part with fine, apparently unsocketed hairs. Ninth legs (Fig. 3) with broad, short coxae bearing anterior cuticular fimbriae and short, medially toothed processes; prefemora about twice as long as distal articles, latter pyriform.
1. According to Shear (1981), these two nominal species are likely synonyms.
Female paratype: Length 5.2 mm, width ca. 0.40 mm, nonsexual characters as in male.
Habitat. The type specimens were discovered in Tlingit Park under logs and debris on damp, "mucky" substrate in a shallow ditch that appears to carry overflow water periodically. The ditch runs down a slope into a small wooded area but is bordered on each side by a row of cottonwood trees (Populus balsamifera) along the stretch where RMS discovered the specimens.
Distribution. Known only from the type locality.
Etymology. The species epithet is an adjective referring to the Tlingit tribe of native Alaskans.
