Rhynchortalia moresby
sp. n.
(
Figs. 6
,
29
,
73–76
)
Diagnosis
: Similar to
R. insueta
and
R. riedeli
and is distinguished only by male genitalic features (
Figs. 73– 76
). Externally similar to
R. insueta
, but larger with somewhat dull violet iridescent elytra, and hypomeral shelf scarcely or not visible in dorsal view. Males can be separated from other
Rhynchortalia
species
by the angularly notched last abdominal ventrite (
Fig. 29
).
Description
:
Male
: Length: 3.5–4.0 mm; width: 2.0–2.5 mm. Form elongate oval, dorsum moderately convex. Head and pronotum yellow, elytra dull iridescent violet or dull brown to black with a metallic hue and yellowish–testaceous apices. Antenna, pronotal hypomera, prosternum, pro- and mesothoracic legs, and abdominal ventrites yellowish, mesocoxae and tibiae slightly infuscate to darker brown, metathoracic legs dark brown with lighter tarsi. Head with inner margin of eys gradually divergent posteriorly, lenticular below antennal insertion, frons shallowly depressed; punctures fine, interspaces smooth, shiny. Pronotum finely punctate, punctures separated by 1–3 diameters, interspaces shiny. Elytra with dual punctures, large ones on disc about 2x as large as smaller ones, somewhat shallowly impressed and widely separated, smaller ones on interstices separated by 2–3 diameters, large punctures more numerous laterally than on disc, only slightly coarser, denser and more deeply impressed than those on disc. Pronotal hypomeral shelf scarcely visible above anterolateral corners of pronotum, lobe–like, deeply impressed medially. Abdominal postcoxal lines shallow. Apex of ventrite 5 (
Fig. 29
) broadly, shallowly emarginate, ventrite 6 apex deeply emarginate with angular notch. Male genitalia (
Figs. 73–76
): penis guide about 0.65x as long as parameres in ventral view (
Fig. 73
), apically narrowed to conical apex; parameres broad, outer margins and inner surface densely setose; penis (
Fig. 75
) and penis apex (
Fig. 76
) as illustrated.
Female
: Similar to male, but with the following differences: prothoracic legs yellow; mesocoxae and femora dark brownish, mesotibiae light brown;
metathoracic legs dark brown; ventrite 5 apically subtruncate, ventrite 6 conical.
