Diagnosis. Superficially, males of Archipimima clarkei are most similar to those of A. hamata Razowski & Wojtusiak and A. tylonota (Meyrick) , with a mostly fawn ground color with ill-defined forewing pattern elements, and an evenly arched costa of the forewing ( Fig. 19 ); the forewing is slightly to markedly undulate in males of other congeners and dramatically so in most females. The male genitalia of A. clarkei can be distinguished by the longer sacculus with a triangular spine near its distal end.

Description. Head: Scales of vertex and frons mixed cream and pale rust; ocellus small; length of labial palpus ca. 1.5 times diameter of compound eye, with brownish-orange scales on outer surface, paler on inner surface; scaling of antenna pale brown on dorsum, sensory setae ca. 3.0 times width of flagellomere in male, much shorter in female.

Thorax: Dorsum scaling pale tan with narrow rust line at anterior margin, continuing onto basal ca. 0.1 of costa. Male foreleg with short atteriine hairpencil lying along femur ( Brown 1990). Forewing length 9.5‒11.0 mm (n = 4), in males, 12.0 mm (n = 1) in female; forewing apex falcate in both sexes, costa strongly arched in basal 0.15, then nearly straight in male ( Fig. 19 ), costa weakly undulate in female ( Fig. 20 ); forewing ground color pale cream, mostly overscaled with irregular tawny strigulae and specks; short, brown, subrectangular, subbasal dash from costa in male, narrower and paler in female ( Fig. 20 ); pale brown, median fascia extending obliquely outward from near mid-costa, irregular in width and interrupted in male, rather uniform in width and uninterrupted in female; male with pale brown, subtriangular blotch in costal 0.3; female with short, faint, semicircular, postmedial patch from costa; fine, wavy whitish lines extending from near of hind margin extending toward costa, outlining irregular pale bands of speckled ground color; fringe pale brown with narrow, cream outer margin. Hindwing pale yellowish, with faint diffuse patch of pale orange scales at cubital pecten, with pale brown mottling along outer 0.5, most dense at outer margin; three or more small, faint, pale brown spots somewhat evenly spaced between outer margin and base of hindwing; fringe pale brown in apical region, pale cream along lower margin; frenulum with one spine in male, three in female.

Abdomen: Male genitalia ( Fig. 37 ) with tegumen slightly narrowed dorso-posteriorly, vinculum broadly Ushaped; uncus stout, rod-like, curved ventrad in distal 0.25, slightly flattened apically with small ventral brush of fine setae; socii slender, nearly as long as tegumen, with long densely arranged scales; gnathos arms slender with long, upcurved terminal spine-like process at junction of arms; transtilla subrectangular with well sclerotized dorsoposterior margin, a small U-shaped notch medially subtended on each side by a small patch of tiny spines; valva broad, mostly membranous, with broad, well-sclerotized costa and sacculus; sacculus confluent with ventral margin of valva in basal ca. 0.3, then extending into middle of valva, with a small, free, triangular spine near its termination; juxta shield-like; phallus slender, ca. 0.75 length of valva curved at ca. 0.33 distance from base, straight in distal ca. 0.6; vesica lacking cornuti (single preparation—cornuti possibly deciduous and lost). Female genitalia ( Fig. 48 ) with papilla analis simple, mostly parallel-sided, slightly broadened posteriorly, ca. 4 times as long as wide; apophyses relatively long, slender, anteriores slightly longer than posteriores; sterigma membranous medially, with a pair of large, semi-sclerotized lateral ovate lobes nearly meeting at ostium; ductus bursae slender, ca. 2 times as long as corpus bursae, weakly sclerotized and elongate-funnel-shaped in posterior 0.35, only slightly broadened to distinct junction with corpus bursae; corpus bursae round, finely punctate throughout, signum a rather broad, short, hollow fin, with narrow sclerotized margin at junction with wall of corpus bursae, a small membranous lobe-like external capitulum near signum.

Paratypes (13♂, 1♀). Argentina: Tucumán: Ciudad Universitaria , 17 Feb 1959 (8♂, 1♀), 20 Feb 1959 (5♂), USNM slides 154,860, 154,864, J. F. G. Clarke ( USNM).

Distribution and biology. Archipimima clarkei is known from a series of specimens collected at the type locality of Ciudad Universitaria, Tucumán, Argentina, 65 years ago. The life history remains unknown.

Etymology. The specific epithet is a patronym for the late John (Jack) F. Gates Clarke ( USNM), the collector of the type series, who's early work on the fauna of Argentina helped lay the foundation of our knowledge of its microlepidoptera fauna.
