Diagnosis.
This species is nearly indistinguishable externally from A. glabra except for the lack of the depressed lateral 1/3 of the pronotum present in A. glabra (Fig. 43 View Figures 43, 44 ), and its smaller size. Also, it is smaller than A. tethys , whose male has setae on ventrite 6. See diagnosis above. The aedeagus is decisively different (Fig. 28 View Figures 22–31 ), with a relatively long and moderately, narrowly rounded tip.
Description.
Habitus. Very small sized, BL: 4.90 mm and BW: 2.45 mm (range, BL: 4.75-5.00 mm, BW: 2.45-2.60 mm), with rather oval and convex body (Fig. 41 View Figures 41, 42 ). Color and luster. Head dark reddish brown; pronotum, elytra and ventral surface of body black, pronotum marginally diaphanous reddish black; legs deep reddish brown. Deep reddish black medially at the very apical edge of ventrite 6; antennae and palpi brown. Integument moderately dull, with slight, diffused spectral iridescence dorsally and ventrally. Microsculpture and punctation. Dorsal surface of head and pronotum with prominent isodiametric meshes; elytra with irregular mesh of more or less transversely stretched sculpticells; ventral surface with scarcely-visible sculpticells on ventrite 6 and prosternum, otherwise sculpticells mostly not apparent. Head lacking macropunctation or wrinkles on vertex; head, pronotum and elytra without micropunctation. All abdominal ventrites very shallowly wrinkled to nearly smooth. Head. Slightly more than 1/4 as wide as pronotum (Suppl. material 2: Table S1). Eye moderate sized, somewhat protruded, EyW/HW: 1.31. Frontoclypeal sutures not evident. Mentum tooth without paramedial border. Thorax. Pronotum 1 2/3 wider than long (PW/PL: 1.67 (range, 1.71-1.76)), with sides evenly, very shallowly rounded from anterior angles to posterior ones; maximal width in posterior 1/5; width at apex ~ 1/3 that of widest point (PW/PA: 2.88 (range 2.82-3.00)). Posterior angles ~ right angled, broadly rounded. Mesosternum with single, very prominent, medial tubercle. Metepisternum 1 1/2 × wider than long, with lateral margin straight, coadunation with epipleuron along entire length. Elytra. Broad, as wide as long (EL/EW: 1.00 (range, 1.00-1.02)). Basal margin distinct, forming small, sharp tooth at shoulder, ended medially at level of parascutellar punctures, joined to parascutellar puncture fovea by a short, shallow striole. Apical sinuation not evident. Female genitalia. Female specimens unknown. Male genitalia. Median lobe of aedeagus in lateral view long, almost straight (Fig. 38 View Figures 32–40 ); lobe in dorsal view with apical lamella moderately long, rounded, triangular and oriented to right (Fig. 28 View Figures 22–31 ); sclerotized portion of endophallus visible in repose, with two sclerites.
Etymology.
The specific epithet Adelopomorpha tuberculata draws attention to the relatively large, median mesosternal tubercle in these beetles. It is treated as an adjective in the nominative singular.
