5. Rhynchortalia iongai sp. n.

( Figs. 5 View FIGURES 1–12 , 22 View FIGURES 18–29 , 46–49 View FIGURES 30–56 )

Diagnosis: This species is similar to R. papuana in general appearance, but can be distinguished from it by the laterally more broadly rounded pronotum, more broadly yellowish apices of the elytra ( Fig. 5 View FIGURES 1–12 ), and the absence of a distinct pronotal hypomeral shelf. Males can be identified by the last two ventrites which are apically more deeply emarginate than those in R. papuana . The male genitalia in both species are superficially similar, but the penis guide is distinctly narrower in R. papuana and the penis is diagnostic. Besides, in R. papuana , the head is more elongate with narrower eyes, less concave frons with fine, mostly obsolete punctation, the pronotum is more finely punctate, and elytra have much fewer larger punctures on disc.

Description: Male: Length: 4.0–4.5 mm; width: 2.5–3.0 mm. Form ( Fig. 5 View FIGURES 1–12 ) elongate oval, moderately convex. Head and pronotum yellow, elytra black with iridescent hues, apices broadly yellowish. Antenna, mouthparts, pro- and mesothoracic legs, abdominal ventrites 3–6 yellowish, metatibiae dusky brown or infuscate, metathoracic legs dark brown except tarsi lighter, testaceous. Head with frons depressed, medially concave, eyes with inner margins lenticular below antennal insertions, posteriorly divergent, punctures separated by 2–4 diameters on inner ocular margins, middle of frons and vertex with few punctures, interspaces smooth, shiny. Pronotum with punctures separated by 1–3 diameters on disc, denser on posterior margin and sides, more widely separated towards anterior margin, interspaces smooth. Elytra with dual punctures, large punctures not more than 2x as large as smaller ones on disc, smaller ones separated by 2–4 diameters on interstices, larger punctures on lateral sides more deeply impressed, but not much larger than those on disc. Hypomera deeply depressed anteriorly, with hypomeral shelf barely developed or apparently absent. Abdominal postcoxal lines shallow, approximating metacoxal cavity. Posterior margin of ventrite 5 ( Fig. 23 View FIGURES 18–29 ) medially deeply emarginate, ventrite 6 more deeply emarginate, U–shaped, both ventrites densely setose. Male genitalia ( Figs. 46–49 View FIGURES 30–56 ) with tegmen possessing long, apically broad parameres, densely setose on inner and outer margins, penis guide narrow, elongate conical, gradually narrowed from base to acuminate apex in ventral view, ~3/4 as long as parameres. Female: Similar to male except meso- and metathoracic legs more or less completely brown except mesotibiae and all tarsi lighter brown. Abdominal ventrite 5 apically shallowly emarginate, ventrite 6 conical.

Specimens Examined: Holotype, male: New Guinea: SE, Iongai, 1700–1900m, 9.XI.1965 / J. Sedlacek ( BPBM) . Paratypes: with same data as holotype, 1 male and 2 females ( BPBM); NE, Iongai , 10km E of Mt. Albert Edward, 1450–1800m, 8–10.XI.1965 / J. Sedlacek, 1 male, 2 females ( BMNH, BPBM) .

Etymology: The specific epithet is a noun in apposition, and refers to the type locality.

Distribution: New Guinea.
