Description. Body length 0.9–1.3 mm. Brown along dorsum, yellow to light brown ventrally. Face and frons brown; head appearing longitudinally flattened, head height 1.5–1.9 times head length. Interfrontal bristles in 4 subequal pairs, postocellar bristles straight or slightly convergent, 2 pairs of small postocellar setulae. Eye small. Gena striate and devoid of microsetae on dorsal half, with light, reflective polinosity present on ventral half, eye to gena ratio approximately 1.4:1; 2 enlarged genal setae, 2–3 more scattered genal setae.

Thorax light brown dorsally, yellow ventrally. Scutellum with 10–13 discal setae arranged in 2 rows between basal 1/3 and basal 2/3; 2 lateral setae between anterior and posterior marginal bristles. Katepisternum with 2 small, subequal dorsal bristles, each approximately 1/5 as long as distance between katepisternum and wing base. Legs and fore coxa yellow. Mid tibia with 1 proximal posterodorsal bristle at 2/5. Mid basitarsus with anterior row of small, stout bristles, a sub-basal ventral pair of bristles, and 2 ventral rows of small setae along entire length of mid basitarsus. Second costal sector 0.7–0.9 times as long as third costal sector. Costal bypass short, terminating within 5 vein widths of R 4+5.

Male terminalia: Sternite 5 rectangular, with patch of microtrichia posteromedially; discal bristles uniform in size. Sternite 6 straight medially. Epandrium with enlarged pair of dorsolateral bristles; subanal plate present, robust; ventral margin of cercus rounded but unmodified. Surstylus with quadrate posterior process, process covered in dense setae and separated from rest of surstylus by ridge, anterior portion with ventral 90˚ angle. Postgonites straight, narrow on distal 2/5. Basiphallus arched, tubular, closed posteriorly; epiphallus bulbous. Lateral sclerites of distiphallus narrow, with elongate, membranous proximal dorsal process, a bifurcate dorsal process, and a subapical process emerging from medial surface; central process fused with lateral sclerites ventral to bifurcate process. Apical membranes short.

Female terminalia: Tergite 8 unmodified, sclerotized dorsally. Tergite 10 pollinose, narrowly fused to cerci laterally; cerci pollinose, apical bristles long and sinuate. Sternite 7 broad, with blunt posterior point. Sternite 8 rounded, triangular, with lateral groups of 4 small bristles. Sternite 10 convex and rounded, with pair of enlarged medial bristles, posterior margin not curved dorsally. Spermathecae pear-shaped; duct length 3–4 times as long as spermathecal bulb.

Distribution: Nearctic: USA (FL).

Etymology. The specific name is derived from the Latin word testudo, which means “tortoise,” and reflects the biology of this species.

Comments. Coproica testudinea is a rare species only known from gopher tortoise burrows in Florida, and from traps set near their burrows. Small eyes, and the highly specific habitat, make this species easily identifiable.
