Abstract

Background

The Catalogue of Crane Flies of the World accounts for 196 recent species of subgenus Tipula (Vestiplex) Bezzi, 1924 distributed in Nearctic, Palaearctic and Oriental Regions (Oosterbroek 2024). The current paper provides taxonomic review of T. (V.) balioptera with designation of two new synonyms.

New information

Tipula (Vestiplex) perretti Alexander, 1928 is designated as junior synonym of T. (V.) balioptera Loew, 1863. Tipula (V.) bo Mannheims, 1967 is removed from synonymy with T. (V.) tchukchi Alexander, 1934 and designated as the second junior synonym of T. (V.) balioptera. Tipula (V.) tchuckhi Alexander, 1934 is exluded from the list of fauna of Norway, Sweden and Finland and from West Palaearctic Region subsequently.

Introduction

The Catalogue of Crane Flies of the World accounts for 196 recent species of subgenus Tipula (Vestiplex) Bezzi, 1924 distributed in Nearctic, Palaearctic and Oriental Regions (Oosterbroek 2024). Amongst them, 26 species were described as new to science from East Palaearctic and Oriental Regions in the last 8 years (Men et al. 2017, Starkevich et al. 2019a, Starkevich et al. 2019b, Men et al. 2021a, Men et al. 2021b, Men et al. 2021c, Ren et al. 2021, Yang et al. 2021 ,Men et al. 2021a, Men et al. 2021b, Men et al. 2021c ,Men et al. 2023, Starkevich and Young 2023). The current paper provides taxonomic review of T. (V.) balioptera with designation of two new synonyms.

For morphological analysis, terminalia of adult crane flies were removed and boiled in 10% sodium hydroxide (NaOH) for 5–10 minutes and observed in glycerine under an Olympus SZX10 stereomicroscope (Olympus, Japan). Photographs of adult specimens were taken with a Canon EOS 6D camera and Canon MP-E65 mm lens using the MJKZZ automated focus stacking rail set. Pictures of dissected terminalia were taken with an Infinity1 camera mounted on a Nikon Si-L stereomicroscope. The obtained layers were stacked using the programme ZereneStacker and edited with Photoshop. The Norwegian specimen of T. (V.) balioptera was imaged by using a Leica M205C stereomicroscope, Flexacam C1 camera and LAS X software. Digital images were stacked by using Helicon Focus software. Swedish specimens of T. (V.) bo were imaged by using a Canon EOS R and Canon MP-E65 mm lens. A stack was obtained by using Cognisys Stackshot 3X automated focus stacking rail and was processed with Helicon Focus 8 and edited in Photoshop.

Descriptive terminology of the adults generally follows that of Cumming and Wood (2017). The term genital bridge was adopted from Dobrotworsky (1968) which is equal to sclerites sp1 and sp2 (Neumann 1958).

Taxon discussion

The first record of T. (V.) balioptera out of the Nearctic Region was published by Starkevich and Paramonov (2016) with taxonomic account as follows:

= Tipula (Vestiplex) laccata laccata: Savchenko 1964 nec Lundstrom and Frey 1916 (partim), after Starkevich and Paramonov (2016).

A single male specimen from Yakutyia, Russia was detected amongst material identified as T. (V.) laccata by E. N. Savchenko (Savchenko 1964). Another partim of the T. (V.) laccata material belonged to T. (V.) aldrichiana, a species which was also recorded in the Palaearctic for the first time (Starkevich and Paramonov 2016). Later, T. (V.) balioptera was recorded in Mongolia (Starkevich et al. 2020) and Norway (Kolcsár et al. 2023).

Following Mannheims (1971), all material published by Savchenko (1964) as T. (V.) laccata was synonymised with T. (V.) tchukchi Alexander, 1934, including some other material listed below:

Tipula (Vestiplex) tchukchi Alexander, 1934

= laccata Lackschewitz 1936 (partim), Mannheims 1953 (partim), Savchenko 1964, nec Lundstrom and Frey 1916, after Mannheims (1971).

Finally, another species T. (V.) bo Mannheims, 1967 was synonymised by Mannheims and Savchenko (1973) with the taxonomic list as follows:

Tipula (Vestiplex) tchukchi Alexander, 1934

= laccata Lackschewitz 1936, Mannheims 1953, Savchenko 1964, nec Lundstrom and Frey 1916, after Mannheims and Savchenko (1973).

As can be seen from the taxonomic records (Mannheims 1971, Mannheims and Savchenko 1973), besides T. (V.) bo, three partims of T. (V.) laccata material were listed as T. (V.) tchukchi.

After examination of type material of T. (V.) bo and based on morphology analysis, we found that this species belongs to T. (V.) balioptera and thus is a junior synonym:

Tipula (Vestiplex) bo Mannheims, 1967 - Mannheims 1967: 148 syn. nov. stat. res.

= laccata Lackschewitz 1936 (partim), Mannheims 1953 (partim), Savchenko 1964 (partim), nec Lundstrom and Frey 1916.

Subsequently, T. (V.) tchukchi is exluded from the list of fauna from Norway, Sweden and Finland.

Discussion

Discussion on morphology results

Tipula (V.) perretti was described from single male collected in Labrador, Canada by Alexander (1928). No additional material was published after the original description. The specimen was not dissected and limited drawing of male genitalia showing the caudal part of tergite 9 was only provided. In addition, the specific position of tergite 9 was omitted by Alexander, but described in his another work (Alexander 1934): “In a number of species of Vestiplex, the tergal saucer tends to swing ventrad so as to lie on the lower face of the tergite, in which case the only part of the sclerite visible from above is feebly sclerotized cephalic portion, together with the cephalic rim of the saucer, where this is developed. In such cases, when treated with caustic soda, the saucer swings dorsad and cephalad so as to assume its normal position. This curious occurrence was first noted by Mr. Edwards, and unless appreciated may cause confusion in separation of allied species”. The holotype of T. (V.) perretti represents described specific position of tergite 9 (Fig. 1B and C). In addition, inner gonostyli were also not visible due to the specific position of tergite 9. This possibly caused the issue with identification, so that the specimen was described as new species. After specimen examination and genitalia dissection, it turned out that the morphology is identical to that of T. (V.) balioptera, a species widely distributed throughout the Nearctic and Palaearctic (Oosterbroek 2024). The new record of T. (V.) balioptera in Europe stimulated revision of existing literature and material of local T. (Vestiplex) species and, as a consequence, the type material of T. (V.) bo was revised uncovering its identity with T. (V.) balioptera. Males of T. (V.) balioptera can be separated from its nearest ally T. (V.) laccata by details of tergite 9, outer and inner gonostyli. They can be also distinguished by the genital bride. Tergite 9 of T. (V.) balioptera posteriorly has a broad median notch, lateral angle extended, horn-shaped (Fig. 2A and Fig. 3A). In T. (V.) laccata, the posterior margin has a deep and narrow median notch and obtuse lateral angles (Starkevich et al. 2020: fig. 75).

(V.) balioptera can be easily separated by sternite 9 having additional lateral incisions (Starkevich et al. 2020: fig. 48) which are absent in T. (V.) laccata (Starkevich et al 2020: fig. 84).

Hypopygium. Tergite 9 forming a concave sclerotised saucer (Fig. 2A and Fig. 3A). Posterior margin of tergite 9 emarginated, with broad median V-shaped notch, with 2 yellow oblong projections and black median spinous tooth, additional small denticles on either side. Lateral angle of tergite 9 extended, horn-shaped. Anterior part of tergite 9 raised into sclerotised border, its lateral angle terminating into obtuse tooth. Gonocoxite unarmed (Fig. 2B). Outer gonostylus flattened, nearly parallel-sided with apex oblique (Fig. 2C and Fig. 3B). Inner gonostylus in shape of curved plate, dorsally with small acute spine, beak extended into rostrum with distal margin blackened, tipped with small tooth (Fig. 2D and Fig. 3C). Genital bridge with its sp1 forming anterior apodeme, posterior apodeme nearly triangular; sclerite sp1 well developed, bilobed (Fig. 2E and Fig. 3D). Aedeagal guide relatively narrow tube-shaped structure (Fig. 2F). Sperm pump with compressor apodeme having median incision (Fig. 2G). Posterior immovable apodeme slightly longer than compressor apodeme and slightly broadened. Anterior immovable apodeme irregularly-shaped. Aedeagus with distal part ventrally membranous, shovel-shaped (Fig. 2H).

Variation. The tergal median denticle on posterior margin of tergite 9 shows some variations, from single, obtuse (Fig. 2A) to stout (Fig. 3A) or split (Fig. 4A and B).
