Diagnosis
. This species is distinct from any other
Platyderus
from the Apennines by the median lobe of aedeagus, that is wider and appreciably humpedbacked in middle, with apex markedly inclined ventrally (
Figs. 4
,
8
) and the copulatory piece with single right-sided lobe protruding in front (
Figs. 10
,
14
).
Description
. A micropterous
Platyderus
species with microsculpture of tegument isodiametric, distinct on labrum, vertex and elytra. Colour dark brown; antennomeres, palpomeres and legs yellow-red. Size measurements and ratios are shown in Table 1.
Head round, dorsal surface impunctate. Eyes moderately big, flat, moderately prominent. Labrum slightly emarginate anteriorly. Mandibles shorter than half length of head (with mandibles). Antennae pubescent from article 4, article 11 and half of article 10 exceeding base of pronotum. Disc smooth, frontal impressions distinct, obliquely shaped. Pronotum subrectangular, widest before and in middle. Lateral, anterior (excluding medial tip) and posterior margins beaded. Sides more convex towards apex, less convex to base; anterior margin emarginate; posterior margin convex near angles, emarginate in middle. Basal impressions short, longitudinal, sublinear.
Hind
angles obtuse, more or less distinct. Disc slightly vaulted, midline distinct, not reaching anterior and posterior margin. Elytra coalesced along suture, widest after middle, narrower at apical third. Shoulders obtusely angulate, not denticulate. Basal bead complete; scutellar striae and scutellar SP present; elytral striae impunctate, equally deep anteriorly and posteriorly, all reaching basal margin; intervals flat, without punctuation.
Hind
wings reduced. Pro-, meso- and metasternum smooth; anterior and internal margins of metaepisternae of equal length. Abdomen smooth. Legs relatively long, slender.
Male genitalia (genitalia of
9 specimens
studied): Median lobe of aedeagus in lateral view thinner basally and apically, widest and appreciably humpedbacked in middle, apex distinctly inclined in front (inclination of apex at 35º–45º in relation to medial part of ventral margin) (
Figs. 4
,
8
); same ventrally thinner in base (
Fig. 14
). Copulatory piece convex laterally, ventrally with single right-sided lobe protruding in front (
Figs. 4
,
10
,
14
).

Chaetotaxy: the arrangement of the dorsal setae of elytra varied. Usually, interval 3 of each elytron with 3 SP, first SP and second SP situated in stria 3, and third SP - in stria 2. However, in one specimen first SP on one elytra is missing, and in another specimen – the second SP. Other two specimens possess 4 dorsal SP on one of two elytron (as last two SP are situated in last third of elytron), and right elytron of
holotype
before middle with one additional SP at stria 4.
Etymology
. Dedicated to the late Mr. Gustav Paganetti-Hummler (
1871–1949
) who collected the new species. Paganetti-Hummler was a prominent Austrian collector in the early part of the XX century, particularly working in Southern Europe.
