DIFFERENTIAL DIAGNOSIS. The two known species of
Ronhuberia
Moravec, Kudrna, 2002
are characterized by their elytral surface which is almost smooth and chatoyantcoloured posteriad of discal impression with widely diffusing, velvety black central zone that may change to iridescent gold-bronze (depending on light-angles).
Ronhuberia fernandezi
(
Cassola, 2000
)
, the
type
species of the genus, differs in a complex of diagnostic characters [
Moravec, Kudrna, 2002
;
Moravec, 2020
], yet immediately in having immaculate elytra and an extremely coarse sculpture on the elytral base and pronotal surface.
New data about some morphological features as (Table) well as the basic measurements of newly recorded specimens of this extremely rare species are presented below. The coloration and measurements of the
types
are given after
Moravec, Kudrna [2002]
; it must be noted here that the
type
specimens are partly tarnished and faded as usual in very old specimens (
Figs 10–20
).
DIMENSION. With the data on newly collected exemplars the sizes (mm) and proportions of all known specimens of
R. eurytarsipennis
are as follows (males/females): TL — 8.0/7.8–8.5; HW — 2.1–2.15/2.1–2.3; LL — 0.8/0.9–1.05; LW — 0.9/0.9–1.0; LL/LW — 0.89/1.0–1.11;
PL
— 1.5/ 1.4–1.6;
PW
— 1.25/1.1–1.25;
PL
/
PW
— 1.2–1.3/1.24– 1.28; EL — 4.9–5.0/4.8–5.2; EW — 2.2–2.3/2.2–2.4; EL/ EW — 2.13–2.27/2.17–2.18; SL — 0.2–0.25/0.2–0.25; AL — 1.97–2.2.
REMARKS. It is noteworthy that
Wiesner [1992]
catalogued
R. eurytarsipennis
(with a question mark) in a diagnostically very different genus
Pentacomia
Rivalier, 1969
. Similarly,
R. fernandezi
was originally described by
Cassola [2000]
as
Pentacomia
, despite its distinct characters of which he stressed the metallic coloured labrum only.
Moravec, Kudrna [2002]
thoroughly re-described and additionally illustrated these two species, and for their remarkable diagnostic characters, the authors transferred them to a separate genus
Ronhuberia
.
It must be noted here that the genus
Pentacomia
Bates, 1872
diagnostically differs from all other genera of the subtribe
Odontocheilina W. Horn, 1899 sensu
Moravec [2012]
, including all genera which were originally described as subgenera of
Pentacomia
by
Rivalier [1969]
, as demonstrated by
Moravec [2018a
–b, 2020]. The illustrations of the
two type
specimens of
R. eurytarsipennis
(
Figs 10–20
) are the originals taken by the second author of this present paper, also published in
Moravec, Kudrna [2002]
and
Moravec [2020]
