Diagnosis.

Coptocarpus erwini , C. lescheni , and C. magnus all have completely impressed elytral striae. Of these three only C. erwini lacks both the elytral submarginal carina (Fig. 46 View Figures 46, 47 ) and the apicolateral setae of the clypeus (present in C. magnus ). In C. erwini the antennae are pubescent from antennomere 4 (pubescent from antennomere 2 in C. lescheni ).

Description.

Habitus. Medium sized, BL: 8.55 mm and BW: 3.65 mm (range, BL: 8.35-8.80 mm, BW 3.55-3.65 mm) ovate, convex body. Color and luster. Head and pronotum reddish black, elytra black to dark reddish black; ventral surface of body reddish brown to black; legs deep reddish brown, tarsomeres paler brown. Abdominal ventrites reddish black medially and apical edge of ventrite 6; antennae and palpi brown. Integument moderately dull, without spectral iridescence except irregularly ventrally. Microsculpture and punctation. Dorsal surface of head, pronotum, and elytra with prominent isodiametric meshes; ventral surface with scarcely-visible sculpticells or mostly sculpticells not apparent except on ventrite 6 and apically on prosternum. Head lacking macropunctation or wrinkles on vertex; head, pronotum and elytra with scattered micropunctation; abdominal ventrites 1-3 laterally with coarse punctures, becoming finer and less extensive on 3; ventrites 3-5 very shallowly wrinkled laterally, 4 and 5 smooth medially, and 6 smooth throughout. Chaetotaxy. Labrum with six setae, each in its own socket, lateral setae longer than medial four, which are set more closely to each other than to the lateral setae. Clypeal setae absent. Single supraorbital seta absent. Elytron with two discal setiferous punctures in interval 3 ( some× represented by only a puncture). Abdominal ventrites 3-5 with ambulatory setae. Head. Approximately 1/3 as wide as pronotum (Suppl. material 2: Table S1). Eye size moderate, eye somewhat protruded, EyW/HW: 1.30 (range 1.24-1.30). Labrum with anterior margin deeply emarginate. Frontoclypeal sutures not evident. Antenna moderate length, with last segment nearly reaching pronotal base and pubescence starting from antennomere 4. Last labial palpomere elongate, blunt at apex, length ~ equal to penultimate one. Mentum tooth without paramedial border. Thorax. Pronotum elongate, 1 1/2 × wider than long (PW/PL: 1.54, (range, 1.48-1.54)); width at apex 2 2/3 × less than at widest point (PW/PA: 2.37 (range, 2.22-2.41)). Disc with midline fine, well impressed, and ended well before apical and basal margins, without apical transverse impression; anterior angles scarcely convex, anterior margin shallowly concave, submarginal sulcus present near angles, lacking in middle 3/5. Prosternal process acuminate, bordered throughout. Mesosternum with single, low medial tubercle. Metepisternum 1 1/3 × wider than long, with lateral margin produced posteriorly, coadunation with epipleuron along entire length. Elytra. Approximately 1/3 longer than wide (EL/EW: 1.27 (range 1.25-1.30)). Basal margin forming prominent, sharp tooth at shoulder, ended medially at level of stria 3. Humeral submarginal carina absent. Elytral apical sinuation not evident. Disc with all striae impressed; parascutellar striole absent or marked by a small, shallow remnant. Elytral intervals flat; granulation in marginal furrow discontinuous, interrupted broadly at midlength. Legs. Mesotibia slightly curved and moderately dilated apically. Basomesotarsus and basometatarsus glabrous dorsally; basomesotarsus in male constricted basally, apically flattened, with 11 or 12 short, stout setae ventrally and many smaller setae scattered on lateral portions. In female, basomesotarsus cylindrical and with scattered, fine dorsal setae and rows of moderately thicker ventral setae. Female genitalia. Gonocoxite 2 elongate. Spermatheca narrow and long, coiled in distal 1/2, undifferentiated; spermathecal gland connected near medial 1/3 of spermatheca. Male genitalia. Median lobe of aedeagus in lateral view long, almost straight, with thin apex slightly flexed ventrally on the left lateral edge (Fig. 33 View Figures 32–40 ); lobe in dorsal view with apical lamella well bent to right, with right side deeply concave and left side straight (Fig. 23 View Figures 22–31 ); basal bulb forming edge dorsally with evident crest; sclerotized portion of endophallus visible in repose with one evident sclerite.

Etymology.

The specific epithet Coptocarpus erwini is treated as a noun in the genitive case and is in honor of Terry Erwin and his amazing, life-long contribution to carabidology.
