(Figs. 1–15)
Etymology. The species is named after the Andes, where the type series was collected.
Diagnosis. This species is quite easily distinguishable from other Mada species by the glabrous surface of elytra and characteristic colouration (for most of the specimens) with light-brown elytra with base, lateral margins and suture black. Male genitalia, with penis apically truncate (not pointed) and penis guide pointed and widest in mid part, are distinctively different from other described species.
Description. Length 3.5–4.3 mm; width 3.0– 3.4 mm; TL/EW = 1.17–1.26; PL/PW = 0.43–0.57; PL/EL = 0.24–0.28; PW/EW = 0.50–0.62; EL/EW = 1.00–1.09.
Body oval, convex; pronotum pubescent, elytra with sparse pubescence at basal and lateral margins only. Head black with anterior margin brown (Fig. 2); pronotum and scutellum black; mouthparts yellowish-brown; elytra light-brown with base, humeral angles, suture and lateral margin black (Fig. 1). Ventral side black with legs and abdomen light-brown. Head and pronotum punctate; elytron dually punctate with punctures almost the same size. Variation: two females totally brown with only pronotum and scutellum black, and posterior angles of elytron darkened (Figs. 3, 4).
Head exposed, transverse; ventral antennal grooves present. Eye finely faceted, with inner orbits emarginated antero-medially. Antennal insertions exposed in front of eyes, close to inner eye margins, with distance between antennal sockets more than six times the distance between antennal socket and inner margin of eye. Antenna shorter than width of head, 11-segmented; scape large, swollen, about twice as long as pedicel; pedicel longer than wide, swollen; antennomere 3 elongate, about as long as antennomeres 4–6 combined; antennomeres 4 and 5 subquadrate; antennomere 6 small, transverse, shorter and narrower than antennomere 5; antennomeres 7 and 8 transverse; antennal club relatively compact, 3-segmented, asymmetrical. Clypeus transverse; labrum transverse with anterior part membranous, covered with setae, anterior margin shallowly emarginate.
Pronotum transverse, widest at base and gradually narrowing anteriorly; anterior and hind margins not bordered; disc convex, finely punctate. Prothoracic hypomeron smooth; notosternal suture distinct; prosternal process with weak grooves along its lateral margins, apex round. Mesoventrite (Fig. 13) with anterior edge emarginate with raised border for entire length; mesoventral process smooth, broader than coxal diameter; mesometaventral articulation with suture straight. Scutellum small, triangular. Elytra at base broader than pronotum; dually punctate with punctures almost the same size; humeral angles well developed; lateral margins narrow, visible from above throughout; elytral epipleuron complete, smooth, with submarginal carina complete; metaventrite with intercoxal process broadly bordered; metaventral postcoxal lines forming straight line with two rounded, setose projections, laterally complete, straight; metaventrite with discrimen complete (Fig. 13).
Legs short and stout (Fig. 13), not protruding from outer margin of elytral epipleuron. Trochanters roundly produced, with cavities on their inner surfaces for receiving tip of tibiae in repose. Femora cylindrical with weak grooves throughout for receiving tibiae. Tibiae with apical spurs of formula 1–2–2, protibiae with weak grooves along entire length for receiving tarsi, mid and hind tibiae on outer edge near apex with oblique carina; tarsal claw double with additional large, subquadrate basal tooth (Fig. 10).
Abdomen with six ventrites in males and five ventrites in females (ventrite 6 detached from male abdomen in Fig. 8). Abdominal postcoxal lines recurved angulately and incomplete, reaching 3/4 length of ventrite 1 (Figs. 5, 7). In males apical margin of ventrite 5 weakly truncate (Fig. 7); ventrite 6 emarginate medially (Fig. 8); tergite VIII rounded (Fig. 9). Apodeme of male sternum IX simple, thin, rod-like. Tergite X subtriangular. In females apical margin of ventrite 5 rounded (Fig. 5); sternite VIII weakly truncate medially (Fig. 6), tergite VIII rounded. Proctiger (TX) membranous, sclerotized only at apical part, transverse, weakly truncate apically.
Male terminalia and genitalia (Fig. 11, 12). Penis guide symmetrical, widest in mid part in lateral view, with pointed apex; slightly longer than parameres. Parameres well developed, simple, setose apically. Penis base with Tshaped capsule. Penis rod-like, slightly curved apically, with truncate and slightly broadened apex.
Female genitalia (Fig. 14). Coxites suboval, about as broad as long, with inner margins rounded, styli present. Bursa copulatrix ending with sperm duct; sperm duct short, simple; spermatheca small, membranous, vermiform, without clear nodulus and ramus; accessory gland longer than spermatheca. Oviduct diverges in mid part of spermatheca, with symmetrical sac-like structures.
