Description. Body length 1.6–2.1 mm. Body brown or light brown. Face light brown, frons brown. Interfrontals in 4 pairs, postocellar bristles slightly convergent, 1 pair of small postocellar setulae. Eye to gena ratio approximately 2:1; 3 small genal setae arranged in a longitudinal row posterior to vibrissa with anterior seta approximately 1.5 times as long as posterior 2.

Scutellum with approximately 15 setae arranged in 2–3 sparse rows between basal 1/4 and basal 1/2; 2 lateral setae between larger anterior and posterior marginal scutellar bristles. Katepisternum with 2 dorsal bristles, anterior and posterior bristles each approximately 1/5 and 1/2 as long as the distance between dorsal margin of katepisternum and wing base respectively. Legs and fore coxa light brown. Mid tibia with posterodorsal bristles at 1/4 and 1/2. Mid basitarsus with stout subapical anterior bristle, a stout sub-basal posteroventral bristle paired with a smaller anteroventral sub-basal bristle, and stout anteroventral bristle at 1/2 paired with a smaller posteroventral bristle. Second costal sector 0.8–1.0 times as long as third costal sector. Costal bypass short, terminating within 5 vein widths of R 4+5.

Male terminalia: Sternite 5 rounded rectangular with posteromedial patch of microtrichia, bristles uniform in size. Sternite 6 without medial bend, but right apex gently curved posteriorly. Epandrium without enlarged pair of dorsal bristles; subanal plate apparently absent, epandrium not clearly delimited from perianal field ventromedially; ventral margin of cercus with long rounded medial process. Surstylus with claw-like posteroventral process, posterior and ventral margins lined with short bristles, claw-like process composed of pointed posteroventral process, and rounded anterior process. Postgonites symmetrical, clubbed and curved laterally at apex. Basiphallus gently curved, open posteriorly; epiphallus with elongate, acute crest. Lateral sclerites of distiphallus with posterodorsal angle reduced, with 1 sharp medially deflected dorsal process, lateral surface covered in small membranous warts distally; central sclerite not fused to lateral sclerites, and with paired, dorsally deflected apical processes. Membranous sheets narrow, with few sclerotized ridges subapically.

Female terminalia: Tergite 8 long laterally, short dorsally. Tergite 10 pollinose, narrowly fused to cerci laterally; cerci conical and pollinose, apical bristles long and sinuate. Sternite 7 broad and rounded. Sternite 8 rounded, trapezoidal, and wider anteriorly, with 3–4 posterior bristles. Sternite 10 with medial pair of large bristles, posterior margin curved dorsally. Spermathecae cylindrical; duct length 5–7 times as long as spermathecal bulb.

Type material. Holotype male: ECUADOR: Galapagos, Española Bahia Manzanillo , 7–10.vi.1985, sand beach, carrion tp., S.&J. Peck ( QCAZ) . Paratypes: ECUADOR: Same as holotype (6♂ *–ill–w, 8♀ *–ill, QCAZ) .

Distribution: Neotropical: Galapagos Is. ( Ecuador).

Etymology. The specific name refers to the Galapagos Islands, the only collection locality for this species.
