Abstract. The following three new species from Eocene Baltic amber are described and illustrated: Ptinus
(Gynopterus) electron sp. nov., Ptinus (Gynopterus) fantii sp. nov. and Ptinus (Gynopterus) groehni sp. nov. Three
other species are recorded: Ptinus (Gynopterus) balticus Bellés & Vitali, 2007 (Poland), Ptinus (Gynopterus)
burukovskyi Alekseev, 2014 (Russia), Ptinus (Gynopterus) scalovicus Alekseev, 2014 (Russia) and Sucinoptinus
sucini Bellés & Vitali, 2007 (Russia).
INTRODUCTION
The family Ptinidae, subfamily Ptininae, tribe Ptinini from Eocene Baltic amber was
recently studied and new articles were published (Alekseev 2012, 2014, Bellés & Perkovsky
2016, Bellés & Vitali 2007, Bukejs et al. 2018, Alekseev, Bukejs & Bellés 2019). The
subfamily contains 10 species from Baltic and Rovno ambers. The present contribution
summarizes material of ambers inclusions with Ptinini from collection of Carsten Gröhn
(Germany) and offers descriptions of three new species.
The article follows preceding articles dealing with Ptinidae, recently published by the
present authors (Zahradník & Háva 2014, 2017 and Háva & Zahradník 2019).
MATERIAL AND METHODS
Species described here were compared with other species from Baltic amber or with
data in descriptions. The type material of the newly described species are deposited in the
following collections:
GPIH Geologische-Palaentologische Institut of University Hamburg, Germany (coll.
Carsten Gröhn);
JHAC Jiří Háva, Private Entomological Laboratory & Collection, Únětice u Prahy,
Prague-West, Czech Republic.
The following measurements were made:

Total length (TL) - linear distance from head to apex of elytra.
Elytral width (EW) - maximum linear transverse distance.
Specimens of the presently described species are provided with a red, printed label with
the text as follows: „HOLOTYPE (or PARATYPE, respectively) species name sp. nov. J.
Háva & Petr Zahradník det. 2019”.

Ptinus (Gynopterus) fantii sp. nov.

bought from amber traders C4053, (GPIH). Paratypes: (4 spec., not sexed): the same data but C8022 (JHAC);

Description. Body: TL 2.8 mm, EW 1.6 mm, subparallel-sided, integument uniformly
piceous, tarsi dark brown (Figs. 1-2).
Head: antennal insertions close to each other, interantennal space narrow and flat, eyes
hemispherical, prominent, finely facetted, ommatidial setae absent, antennae 11-segmented,
comparatively long (Fig. 3).
Pronotum (Fig. 3): short and broad with four bumps covered by brown setation.
Scutellum: large, subtriangular, rounded apically, covered by dense and very short
accumbent yellowish setation.
Elytra: subparallel in basal part, ovate behind, widest in the middle, 1.1 times as long
as wide, humeri with long, narrow bump, surface shining, with fine punctures arranged
in regular striae, strial punctures large, round and shallow, regularly spaced, distances
between punctures equal to two lengths of each puncture, setation sparse, formed by rows of
semierect hairs on intervals and by accumbent hairs in strial punctures.
Abdomen: all five abdominal ventrites delimited, with suture lines well apparent, surface
smooth, covered with short, thin and pale hairs.
Legs: tarsal formula 5-5-5, legs relatively robust, trochanter short, its apex not reaching
elytral margin, tarsi with broad and equal in length tarsomeres I-IV, penultimate tarsomere
not lobed, ultimate tarsomere longer than each of previous, claws simple, long and equal in
length.

Differential diagnosis. The new species differs from the known fossil amber species by the
four bumps on pronotum and structure of antennae.
Etymology. Dedicated to colleague Fabrizio Fanti (Piazze, Italy) well known specialist in
fossil Cantharidae (Coleoptera).
