Abstract

Four new species are described: Pseudepipona (Deuterepipona) kostylevi Fateryga, sp. nov. (Turkmenistan, Uzbekistan, Kazakhstan), P. (D.) nikolayi Fateryga, sp. nov. (Kazakhstan), P. (D.) popovi Fateryga, sp. nov. (Turkmenistan), and P. (D.) vladimiri Fateryga, sp. nov. (Kazakhstan). A new synonymy is proposed: Pseudepipona (Deuterepipona) superba (Morawitz, 1867) = P. (D.) tricolor Gusenleitner, 1976, syn. nov. Lectotypes are designated for two species: Pseudepipona (Deuterepipona) herzi (Morawitz, 1895) and P. (D.) superba. Two species, both not occurring in the region under study, are transferred to the subgenus Deuterepipona from the nominotypical one: Pseudepipona (Deuterepipona) priesneri Gusenleitner, 1970 and P. (D.) pseudominuta Gusenleitner, 1971. An identification key to all six species of the subgenus Deuterepipona from Central Asia is provided.

Introduction

Pseudepipona de Saussure, 1856 is a genus of solitary wasps in the subfamily Eumeninae with 39 hitherto described species. Most of them occur in the Palaearctic region except two Afrotropical species; one species is also found in India and another one is present in both the Palaearctic and Nearctic region (Carpenter et al. 2010; Girish Kumar et al. 2017; Kim 2020; Bai et al. 2021; Fateryga 2022). The genus Pseudepipona includes two subgenera: Deuterepipona Blüthgen, 1951 and Pseudepipona s. str. Seven Palaearctic species were hitherto recognized in the subgenus Deuterepipona (Giordani Soika 1970; van der Vecht and Fischer 1972; Fateryga et al. 2017). The bionomics of the genus were recently summarized by Fateryga (2022); those of the subgenus Deuterepipona are unknown. Two species of the subgenus Deuterepipona have been reported from Central Asia: Pseudepipona herzi (Morawitz, 1895), distributed in Israel, Turkmenistan, Kyrgyzstan, Kazakhstan, Mongolia, and China (Kurzenko 1977; Oehlke 2012), and P. tricolor Gusenleitner, 1976, distributed in Russia, Iran, and Kazakhstan (Dvořák and Castro 2007; Gusenleitner 2013).

In this paper, four new species of Pseudepipona (Deuterepipona) are described from Central Asia and one species is synonymized; lectotypes of two species are designated. Two species, both not occurring in the region under study, are transferred to the subgenus Deuterepipona from the nominotypical one. As a result, 42 species of the genus Pseudepipona are currently recognized: 12 in Deuterepipona and 30 in Pseudepipona s. str.

Materials and methods

The material for the present study was mainly from the collection of the Federal Scientific Center of the East Asia Terrestrial Biodiversity of the Far Eastern Branch of the Russian Academy of Sciences, Vladivostok, Russia [FSCV]. Type material was also studied in the Zoological Institute of the Russian Academy of Sciences, Saint Petersburg, Russia [ZISP]. Some additional type specimens were examined by photos from the collections of the Naturalis Biodiversity Center, Leiden, The Netherlands, and the Stuttgart State Museum of Natural History, Stuttgart, Germany.

Photographs of the specimens were taken with a Canon EOS 550D digital camera and a Yongnuo YN-14EX macro flash attached to an Olympus SZ60 stereomicroscope. Multifocus images were created from stacks of photographs using CombineZP software. The final illustrations were postprocessed for sharpness, contrast, and brightness using Adobe Photoshop CS2 software. Male genitalia were extracted after re-softening the specimens and were then boiled in 10% NaOH for 5 min. After that, they were rinsed in 80% ethanol and only then stored and studied in glycerin.

Species delimitation is based on the external morphology and the structure of the male genitalia. No subspecies based on different coloration are recognized within species according to Carpenter (1987) and Fateryga et al. (2021).

In morphological descriptions, the letter “F” refers to antennal flagellomeres, the letter “T” to metasomal terga, and the letter “S” to metasomal sterna.

Distribution

Remarks

This species is very variable in coloration. Females from Southern Kazakhstan (Fig. 2A, B) differ from the typical form (Fig. 1A, B, D) by the absence of the spot on the dorsal mesepisternum and a completely black clypeus while females from Southeastern Kazakhstan (Fig. 2C, D) differ from the typical form by a completely yellow clypeus. Females from Eastern Kazakhstan (P. herzi kozlovi, Fig. 2E, F) differ from all other forms by an orange-yellow pattern instead of a pure yellow. No differences were found in the male genitalia between specimens from Turkmenistan and Southern Kazakhstan while males of the form from Eastern Kazakhstan were not examined, nor were males of P. herzi enslini. Both subspecies are probably conspecific with P. herzi but need further study.

Description

Female. Body length (from head to apical margin of tergum 2) 6.5–7.0 mm; fore wing length 6.0 mm.

Head about 1.1× as wide as long in frontal view. Clypeus as wide as long; its apical emargination very shallow, about 0.2× as deep as wide, taking 1/4 of clypeal width, apical teeth blunt. Cephalic fovea shallow but well developed, as broad as distance between lateral ocelli; distance between lateral ocellus and occiput 1.1× as distance between lateral ocelli. Pronotal carina well developed, forming blunt angle at anterolateral corner of pronotum. Epicnemial carina developed. Scutellum and metanotum convex.

Frons and vertex with punctures coarser than those on clypeus, interstices usually less than puncture diameter; punctures on gena slightly smaller and sparser. Pronotum dorsally with punctures similar to those on vertex; lateral part of pronotum with denser and smaller punctures and dull interstices with distinct microsculpture. Sculpture on scutum coarser than that on dorsal surface of pronotum, interstices usually less than puncture diameter. Tegula nearly smooth, with few minute punctures. Punctures on mesepisternum, scutellum, and metanotum similar in size to those on dorsal surface of pronotum, interstices usually approximately equal to puncture diameter except whitish parts where they exceed puncture diameter. Mesepimeron with coarse punctures forming longitudinal rows. Metapleuron dull, weakly longitudinally rugose. Dorsal and dorsolateral surfaces of propodeum with shallow irregular, indistinct but coarse punctures similar in size to those on metanotum. Lateral surface of propodeum longitudinally rugose, more distinctly than metapleuron, without punctures. Propodeal concavity transversally rugose. T1 and T2 with dense coarse punctures similar to those on frons and vertex, interstices usually less than puncture diameter except apical bands where punctures are smaller. T3–T5 with sparser and smaller punctures. T6 mostly with microsculpture only. Sculpture of S1 similar to that of lateral part of T1. Basal part of S2 before transverse furrow dull, with microsculpture only. Sculpture of distal part of S2 after transverse furrow and S3–S6 as that of corresponding terga but interstices larger and microsculpture more distinct.

Setation weakly developed. Frons, vertex, dorsal surface of pronotum, scutum, and tarsi with sparse setae less in length than diameter of scapus at base. Posterior margin of gena with very short setae equal in length to puncture diameter on gena. Most other parts of body bare or with very minute setae.

Basal color black. The following parts whitish: spot on frons between antennal sockets, anterior and lower faces of scapus, small band along inner margin of eye from clypeus to ocular sinus, small spot on gena, large lateral spots on dorsal surface of pronotum, spot on dorsal mesepisternum, tegula and parategula, bands on scutellum and metanotum, lateral spots on propodeum, front leg from middle of femur onwards, middle leg from apex of femur onwards, hind leg from tibia onwards, apical bands on T1 and T2 enlarged laterally, apical bands on T3–T4, spot on T6, apical band on S2, apical spots laterally on S3. Ventral side of flagellum ferruginous. Wings transparent, without infuscation.

Male. Body length (from head to apical margin of T2) 5.5 mm; fore wing length 5.0 mm.

Structure as in female but clypeus with apical emargination taking about 1/3 of clypeal width. F11 rather acute, straight, and small, narrowing towards apex, hardly reaching apical margin of F8. Cuspis without the dorsal process typical of some species in the nominotypical subgenus (see Fateryga 2022). Aedeagus as in Fig. 3B, G, median expansion comparatively narrow, ventral lobe in lateral view saddle-shaped, with distinctly emarginated ventral side.

Sculpture similar to that in female but punctures on clypeus shallower. T6 and S6 punctate similarly to previous segments. T7 and S7+8 mostly with microsculpture only.

Setae as in female.

Coloration mostly as in female but mandible, labrum, and clypeus whitish-yellow, spot on frons and band along inner margin of eye larger, entire scapus and ventral side of pedicel whitish-yellow, all legs whitish-yellow from femur; whitish spots on dorsal mesepisternum and propodeum reduced. Entire F10 and F11 ferruginous. T7 and S7+8 black.

Etymology

The new species is named after the Soviet entomologist Georg Kostylev, also known as Yuriy A. Kostylev (1889–1942), in recognition of his great contribution to the systematics of Central Asian Vespidae.

Distribution

Turkmenistan, Uzbekistan, Kazakhstan (Kyzylorda Province).

Diagnosis

The new species can be easily recognized among other representatives of the subgenus Deuterepipona by the pronotal carina rounded laterally, a nearly indistinct cephalic fovea in the female, a robust F11 in the male, and a triangle-shaped ventral lobe of the male aedeagus (see Key).

Description

Female. Body length (from head to apical margin of tergum 2) 6.0–7.0 mm; fore wing length 5.5–6.0 mm.

Head about 1.1× as wide as long in frontal view. Clypeus as wide as long; its apical emargination shallow, about 0.2× as deep as wide, taking 1/4 of clypeal width, apical teeth blunt. Cephalic fovea nearly indistinct; distance between lateral ocellus and occiput 1.2× as distance between lateral ocelli. Pronotal carina weakly developed, pronotum rounded at anterolateral corner. Epicnemial carina developed. Scutellum convex, slightly impressed at center; metanotum convex.

Frons and vertex with punctures much denser and coarser than those on clypeus, interstices reaching puncture diameter; punctures on gena slightly smaller and sparser. Pronotum dorsally with punctures similar to those on gena; lateral part of pronotum rather longitudinally wrinkled, with interstices dull due to microsculpture. Sculpture on scutum coarser than that on frons and vertex, interstices reaching puncture diameter; punctures sometimes form longitudinal rows, especially posteriorly. Tegula nearly smooth, with few minute punctures. Punctures on mesepisternum similar in size and density to those on scutum. Punctures on scutellum similar in size to those on dorsal surface of pronotum but interstices larger, reach several puncture diameters, shining; metanotum with similar punctures in proximal half and nearly smooth distally. Mesepimeron with coarse punctures similar in size to those on mesepisternum but interstices narrower, sharp. Metapleuron longitudinally rugose, with microsculpture but slightly shining. Dorsal and dorsolateral surfaces of propodeum with shallow irregular, indistinct but coarse punctures. Lateral surface of propodeum longitudinally rugose, dull.

Remarks

Examination of the photos of the holotype (Fig. 8A–D) and the paratype of P. tricolor from the Naturalis Biodiversity Center in Leiden revealed no significant differences between this species and P. superba besides the coloration. Although the lectotype of P. superba has a reddish clypeus (Fig. 7D), the clypeus of all other specimens examined (including the ones from the type locality) is either entirely black or with basal reddish spots laterally as corresponds to P. tricolor. Pseudepipona superba is closely related to P. herzi and these two species are distributed allopatrically. The differences between them are mainly in the coloration.

Remarks on two extralimital species

Pseudepipona priesneri Gusenleitner, 1970

Pseudepipona priesneri Gusenleitner inBlüthgen and Gusenleitner 1970: 5, 10–11, ♀ ♂; type locality: “Jarrahi Ufergebiet, 18 km nordöstl. Shadegan, Khuzistan” [Iran].

Distribution

Saudi Arabia, Iran (Blüthgen and Gusenleitner 1970).

Remarks

This species was described without indication of the subgenus and thus was then placed in the nominotypical one by default. However, P. priesneri fits the diagnosis of the subgenus Deuterepipona. Particularly, the male mandible is without a notch between the basal and preapical teeth (Blüthgen and Gusenleitner 1970). Photos of a female and a male paratypes of this species from Iran (Stuttgart State Museum of Natural History, Stuttgart, Germany) were examined to confirm this. It is also of note that P. priesneri is very closely related (or may be even conspecific) to P. herzi; the differences between them are only in the coloration. Therefore, a further study of the specimens (not photos) is necessary to confirm the taxonomic independence of P. priesneri.

Pseudepipona pseudominuta Gusenleitner, 1971

Pseudepipona pseudominuta Gusenleitner inBytinski-Salz and Gusenleitner 1971: 295, ♀; type locality: “Israel, Jericho”.

Distribution

Turkey, Israel (Gusenleitner 2013).

Remarks

Pseudepipona pseudominuta was also described without indication of the subgenus and thus was then placed in the nominotypical one by default. However, this species is “very similar to P. niveopicta” (Bytinski-Salz and Gusenleitner 1971) and the latter taxon has been already transferred to the subgenus Deuterepipona by Fateryga et al. (2017). A female and a male of P. pseudominuta from Turkey (FSCV) were examined to confirm that it fits the diagnosis of the subgenus Deuterepipona. Particularly, the male mandible is without a notch between the basal and preapical teeth.
