description: 4. Rhynchortalia papuana sp. n.   
(Figs. 4, 21, 42–45)  
 Diagnosis: This species can be distinguished by the iridescent black elytra with yellowish apices, hypomeral shelf not visible in dorsal view and the male genitalia (Figs. 42–45).   
 Description: Length: 3.0–4.5 mm; width: 2.5–3.0 mm. Body (Fig. 4) elongate oval, dorsum moderately convex, elytra broadest at humeri, posteriorly narrowed toward apices, covered with silvery white pubescence. Head and pronotum yellow, elytra black with an iridescent sheen, apically yellowish or testaceous, mouthparts, antenna, prosternum, legs and abdomen yellow to yellowish brown, meso– and metaventrites, metacoxae, and middle of abdominal ventrite 1 dark brown to black, epipleura black with testaceous apices, occasionally mesothoracic legs anteriorly infuscate or darker, abdominal ventrite 1 infuscate around postcoxal lines.   
Head with fine, shallow punctures separated by 2–4 diameters, becoming obsolete towards clypeal margin, impunctate and glossy, interspaces shiny; eyes narrow, elongate, with inner margins lenticular or strongly obtusely divergent below antennal insertions. Pronotum with fine, shallowly impressed, dense punctures separated by 2–4 diameters, interspaces smooth and shiny. Elytra with dual punctures, fine, shallow punctures on disc interspersed with few larger ones separated by 2–5 diameters, lateral sides with coarser, deeper and more closely spaced punctures than those on disc, 2–4x as large as finer ones, interspaces shiny. Pronotal hypomera with an obtriangular shelf–like projection on anterior inner half, its anterior edge not projecting beyond anterolateral margin of pronotum. Anterior margin of mesoventrite medially shallowly emarginate. Abdominal postcoxal lines extremely shallow, closely associated with metacoxal cavity. Posterior margin (Fig. 21) of ventrite 5 and 6 in male broadly, shallowly emarginate and deeply emarginate with a broad, U–shaped notch, respectively, and fringed with long, heavy pubescence. Ventrite 5 and 6 posteriorly broadly arcuate and elongate conical, respectively, in female. Male genitalia (Figs. 42–45) with tegmen possessing long, apically broad parameres, inner surface with long setae denser than those on inner and outer margins, penis guide narrow, elongate conical, gradually narrowed from base to an acuminate apex in ventral view, about 3/4 as long as parameres; penis (Fig. 44) and penis apex (Fig. 45) as illustrated.
