Description

provided by Zookeys
Size and shape: Beetle small (TL-H 3.45–3.75 mm, TL 3.8–4.1 mm, MW 1.9–2.1 mm), with oblong-oval habitus, broadest at elytral middle. Coloration: Teneral beetles yellow to yellowish red, mature ones reddish-brown to brown with reddish anterior part of head, pronotal sides, and sutural bands of elytra; head appendages yellow to red, legs darker distally, especially hind legs (Fig. 31). Surface sculpture: Head with very dense punctation (spaces between punctures 1–2 times size of punctures), evidently finer and sparser anteriorly; diameter of punctures equal diameter of cells of microreticulation. Pronotum and elytra with finer, sparser, and more evenly distributed punctation than on head. Pronotum and elytra with rather strongly impressed microreticulation, dorsal surface, thus, submatt. Head with microreticulation stronger. Metaventrite and metacoxa distinctly microreticulate, metacoxal plates with longitudinal strioles and transverse wrinkles. Abdominal sternites with distinct microreticulation, strioles, and fine, rather dense punctation, coarser and denser on two last abdominal sternites. Structures: Pronotum with distinct lateral bead. Base of prosternum and neck of prosternal process with distinct ridge, smooth and slightly rounded anteriorly, with small anterolateral extensions. Blade of prosternal process lanceolate, rather narrow, slightly convex, with distinct bead and few setae; neck and blade of prosternal process evenly jointed. Abdominal sternite 7 slightly truncate apically. Male: Antennomeres 3–5 enlarged, 6–8 slightly enlarged (Fig. 5A). Protarsomere 4 with middle-sized, slender, evidently curved anterolateral hook. Protarsomere 5 ventrally with anterior row (double apically) of 21 short setae and posterior row of 5 short setae (Fig. 5B). Abdominal sternite 7 with 3–8 lateral striae on each side. Median lobe with strong submedian constriction and proximal part narrower in ventral view, apex of median lobe rather broad in lateral view (Figs 5C, D). Paramere with shallow notch on dorsal side and subdistal part elongate, with less numerous, long, thin setae (Fig. 5E). Female: Antennae simple, abdominal sternite 7 without striae.
