on the territory of Ukraine. Studia Biologica, 18(4), 203–210. doi:10.30970/sbi.1804.803
Background. Dryudella is a Holarctic genus, which includes 58 species. The
majority of them, however, 29 species in particular, are common in Palearctic. On
the territory of Ukraine the genus was represented by four species, collected in the
Eastern, Southern and Central Ukraine. The biology of the species of this genus has
been insuciently studied; its certain aspects having been studied only for a few
representatives of the genus.
Materials and Methods. A specimen of a wasp was captured with the help of
an entomological net using the method of selective catching on the territory of the
Hrabunske department of Nature Reserve “Rivnenskyi” (https://www.inaturalist.org/
observations/250256988). The species of the wasp was identied using appropriate
descriptions and keys. The biotope in which the wasp was captured was identied with
the help of the National Catalogue of Biotopes of Ukraine.
Results and Discussion. A new species of wasp of the genus Dryudella was
registered in the territory of Ukraine – Dryudella lineata Mocsáry, 1879 of the family
Crabronidae (Apoidea: Crabronidae: Astatinae). The specimen female D. lineata was
captured in July 2024 in the territory of Nature Reserve “Rivnenskyi”, in a pine forest in
a sandy area. D. lineata is a rare and scarce species of wasp. It has only been recorded
in the territory of eight countries.
Conclusions. First discovery of D. lineata in Ukraine, in particular in Nature Reserve
“Rivnenskyi”. The sample was inventoried (E20 – 3375) and stored in the entomological
collection of the Zoological Museum of the Ivan Franko National University of Lviv.

INTRODUCTION
The genus Dryudella Spinola, 1843 belongs to the family Crabronidae, subfamily
Astatinae. Until 1969, genus Dryudella was considered synonymous and equated to the
genus Astata Latreille (Parker, 1969). It was only in 1969 that Parker distinguished the
genus from synonymy, 1796 (Olszewski et al., 2021).
Dryudella is a Holarctic genus, while the majority of species (29) occur in Palearctic
(Bohart & Menke, 1976). In the world’s fauna, the genus is represented by 58 species
(Pulawski, 2024). Of these, four species have been recorded in the territory of Ukraine:
Dryudella picticornis (Gussakovskij, 1927), D. pinguis (Dahlbom, 1832), D. stigma
(Panzer, [1807–1809]), D. tricolor (Vander Linden, 1829). The specimens were collected
on the territories of Kyiv, Cherkassy, Kharkiv, Kherson and Crimea regions by 2010
(Pulawski, 2024).
Three species (D. pinguis, D. stigma, D. tricolor) were included in the list of Male
Polissia wasp species, but their exact location was not mentioned (Voblenko et al., 1996).
The biology of most representatives of the genus Dryudella has been little studied
(Bohart & Menke, 1976). It is known that representatives of the Astatini build their nests
in the form of burrows in the ground and ll them with paralysed prey (Olszewski et al.,
2021). These wasps build their nests in dierent types of soil. They can be single or
multiple cell. Among the prey, nymphs of Heteroptera were most common, especially
representatives of the Lygaeidae family, and less often Alydidae, Coreidae, Cydnidae,
Pentatomidae, Reduviidae, Rhopalidae and Scutelleridae (Bohart & Menke, 1976).
The species of wasp Dryudella lineata Mocsáry, 1879 – was recorded by us for
the rst time in the territory of Ukraine, in particular on the territory of Nature Reserve

“Rivnenskyi”, the Hrabunske department. The reserve is located in the north of Ukraine
(Rivne region). It belongs to Male Polissia. It consists of four distant massifs: Biloozerskyi,
Somyne, Syra Pogonia and Perebrody with the total area of 42288,7 ha. Within the massif
there are six departments: Biloozerske, Bilske, Hrabunske, Karasynske, Starosilske
and Pivnichne. The territory of the reserve is characterised by the predominance of
swamps, which occupy 20,287.8 ha of the total area and the remaining 21,292.2 ha are
forests (Chronicle of nature, 2020).
D. lineata was rst described by Mocsáry, A. in 1879 (Mocsáry, 1879). The specimen
was captured in the territory of Hungary.
MATERIALS AND METHODS
The specimen of D. lineata was collected by the author S. Pytel-Huta using an
entomological net by the method of selective catching in the territory of Nature Reserve
“Rivnenskyi”, Hrabunske department, quarter 25 (Fig. 1).
Fig. 1. Map of Hrabunske department (Nature Reserve “Rivnenskyi”), the site of the discovery
The National Catalogue of Biotopes of Ukraine and the Habitats Directive
(classication EUNIS) were used to determine the type of biotope in which the wasp was
captured (Onyshchenko, 2016; Kuzemko et al., 2018). Wasp species were identied
using appropriate descriptions and keys using Konus Crystal 7x–45x binoculars (Konus,
Italy) (Bitsch et al., 2007; Dollfuss, 1991; Pulawski, 1955).
The captured specimen of D. lineata complies with the limits for the use of natural
resources within the reserve for the year 2024 (No. 523/2024).
D. lineata are stored in the entomological collection of the Zoological Museum of
Ivan Franko Lviv National University (ZMD). The inventory number is E20 – 3375.
RESULTS AND DISCUSSION
Hrabunske department is part of the Syra Pohonya massif in the Rokytniv district.
It covers an area of 4,499.0 hectares. The massif lies in the proximity of Vezhitsa, Bilsk,
Hrabun and Stare Selo villages (Fig. 2).

Biotope D2.2.1 is represented by dry pine forests on sandy soils with a considerable
amount of lichen (Kuzemko et al., 2018). The most characteristic biotope type for the
north of Volyn and Zhytomyr Polissia. The specimen was captured in a sandy area.
D. lineata is a rare species of wasp. It has been recorded in only eight countries: the
Czech Republic, Hungary, Kazakhstan, Romania, russia, Serbia, Slovakia, Switzerland
(Józan, 1986; Lukáš, 2003; Bogusch et. al., 2007; Smetana et. al., 2010; Józan, 2011;
Pulawski, 2024).
Description: Dryudella lineata – female: body length 6–7 mm, black, the front
tibia and tarsus are light red in colour, while the middle and hind tibia and tarsus are
a much darker shade of dark brown. Lower hind femur with long setae (Fig. 4).
The mandibles are light red at the base and dark at the tip. Antennae are black.
The frons is slightly dotted, shiny. Pronotum weakly punctate, glossy, with a yellow spot
anteriorly. The dorsal feid of the propodeum is irregularly transversely slightly wrinkled,
punctate.

The pronotallobus is yellow. Tegulas are light red. Forewings with three submarginal
cells. The marginal cell is short. The veins of the wings are brown at the base and yellow
at the front of the pterostigma. The rst submarginal vein terminates at the border of
submarginal cells I and II. Metanotum wrinkled, slightly depressed behind.
The abdomen is black, shiny. The pygidial eld is broad, rounded at the end, light
brown at the end, shiny (Fig. 4).
CONCLUSIONS
A rare species of wasp – D. lineata (Hymenoptera: Crabronidae) – was discovered
on the territory of the Nature Reserve “Rivnenskyi” as part of the author's dissertation
research. This is the rst discovery for the territory of Ukraine.

ПЕРША РЕЄСТРАЦІЯ ВИДУ DRYUDELLA LINEATA MOCSÁRY, 1879 р.
(HYMENOPTERA: CRABRONIDAE) НА ТЕРИТОРІЇ УКРАЇНИ

Вступ. Dryudella – голарктичний рід, що включає 58 видів. Проте більшість із
них, зокрема, 29 видів, поширені в Палеарктиці. На території України рід був пред-
ставлений чотирма видами, зібраними у східній, південній та центральній Україні.
Біологія роду мало вивчена, і окремі певні особливості біології дослідженні лише
для небагатьох представників роду.
Матеріал і методи. Екземпляр оси спіймали за допомогою ентомологічного сачка
методом вибіркового відлову на території Грабунського відділення Рівненського при-
родного заповідника (https://www.inaturalist.org/observations/250256988). Визначення
виду оси здійснили за відповідними описами та ключами. Біотоп, у якому спіймали
D. lineata, визначили за допомогою Національного каталогу біотопів України.
Результати. На території України зареєстровано новий вид ос роду Dryudella –
Dryudella lineata Mocsáry, 1879 родини Crabronidae (Apoidea: Crabronidae: Astatinae).
Самку D. Lineata зловили в липні 2024 року на території Рівненського природного
заповідника, в сосновому лісі на піщаній дюні. D. lineata – нечисленний вид ос.
Зафіксований на території лише восьми країн.
Висновки. Перша реєстрація виду D. lineata в Україні, зокрема, на території
Рівненського природного заповідника.
Зразок інвентаризовано (Е20 – 3375) та передано на зберігання в ентомоло-
гічній колекції Зоологічного музею Львівського національного університету імені
Івана Франка.
