Description: Habitus (Figs. 33–34) 3 4.4 mm (mean=4.4, n=2) in length; 2.1 mm (mean = 2.1, n=1) in width. Head: 0.52 as wide as pronotum; punctures small, glabrous; gena glabrous; eyes large finely faceted; frons 0.24 as broad as head across eyes; punctures small, with long erect hair-like scales along margin of eye. Rostrum: 3.6 mm in length; 0.8 as long as body; derm fuscous; base to insertion of scape subcylindrical, then more tubular to apex; continuous with frons; median carinae from base to insertion of scape, lateral carinae dorsal to scrobe flanked by large slit-like punctures; almost straight to insertion of scape then gently deflected to apex; scrobe ventral; scape inserted just past midpoint. Antennae: Scape 1.7 mm, funicle 1.4 mm, club 0.7 mm in length; scape 1.2 longer than funicle; antennomeres 1 and 2 same length; 3 longer than 4, 4–7 same length; club oval-acuminate, as long as 4–7, antennomere 1 of club longer than funicular antennomere 7. Thorax: 1.5 mm in length; 1.5 mm in width; as long as wide; derm rubiginose; disc slightly convex in lateral view; punctures moderately large with moderately long, narrow, erect, fuscous seta-like scales; base sinuate, with small luteous macula of clavate scales anterior to scutellum, widest in middle, gradually rounded to constriction; pleuron with seta-like scales shorter than on disc; mesosternal intercoxal process prominent, clothed with luteous scales; scutellum not as long as wide, densely clothed with clavate luteous scales; mesepimeron derm piceous, glabrous, reticulate; mesepisternum piceous, clothed with short narrow elongate fuscous scales with small macula of clavate luteous scales on distal 1/3; metepisternum piceous and glabrous to distal 1/3, there with macula of clavate luteous scales; metasternum piceous, clothed with small narrow elongate white scales; anteroventral prothorax with macula of clavate, recumbent, luteous scales. Elytra: Striae not deep, with large punctures; shallow scutellar declivity; humeri slightly convex; intervals narrow, clothed with 2 rows of moderately long, erect, fuscous, seta-like scales; interval 1 with short vittae of clavate, luteous scales distad of scutellum; stria 2 with small cluster of clavate, recumbent, luteous scales just past middle; crosshatched setae long, erect, piceous; area piceous from interval 1–5 basally reaching to interval 1 distally to midpoint, with area laterad rubiginose, suture piceous to apex. Legs: Pro-, meso-, and metafemoral teeth medium-sized, thorn-like, metafemur with prominent dorsal node on inner margin of clava; clothed with very small, narrow, elongate, fuscous scales; metafemur exceeding apex of elytra by approximately 1/ 3 of femoral length; tibiae subsinuate, pro-, and mesouncus large; metatibiae with inner shelf, with short tooth on anterior margin. Abdomen: Derm piceous; sternum I as long as II behind coxal cavity; II ascending to III posteriorly; I with broad, deep, median declivity with long, narrow, dirty-white scales along margin; II with median declivity; III–IV equal in length; V longer than III+IV, with median declivity with long, narrow, elongate, testaceous scales along margin. Pygidium: Large; convex; clothed with long, narrow, elongate, fuscous, seta-like scales. Genitalia: Median lobe 1.0 mm in length, almost straight for basal half length then deflexed to apex in lateral view (Fig. 56); in dorsal view, margin wide medially, to before expanded apex (Fig. 55), 0.3 mm in width; apodeme 0.9 mm in length. Female: 4.0 mm in length (n=1); 1.9 mm in width (n=1). Rostrum 4.2 mm in length; femur lacks dorsal node. Genitalia: Dissected but spermatheca not found.
Differential diagnosis: This species can be separated from the others in this genus by the long, erect, seta-like scales; macular pattern; scape longer than funicle and median lobe.
Specific epithet: Name “ crinitus ” derived from the Latin for “having hair, hairy.”
