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.
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.

Abbreviations for institutional collections used herein:
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
Tipula balioptera Loew, 1863 -
Tipula (Vestiplex) balioptera:
= Tipula (Vestiplex) laccata laccata:
= Tipula (Vestiplex) tchukchi:
= Tipula (Vestiplex) tchukchi:
Tipula (Vestiplex) bo Mannheims, 1967 -
Tipula perretti Alexander, 1928 -
The first record of T. (V.) balioptera out of the Nearctic Region was published by
= Tipula (Vestiplex) laccata laccata:
A single male specimen from Yakutyia, Russia was detected amongst material identified as T. (V.) laccata by E. N. Savchenko (
Following
Tipula (Vestiplex) tchukchi Alexander, 1934
= laccata
Finally, another species T. (V.) bo Mannheims, 1967 was synonymised by
Tipula (Vestiplex) tchukchi Alexander, 1934
= laccata
As can be seen from the taxonomic records (
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 -
= laccata
Subsequently, T. (V.) tchukchi is exluded from the list of fauna from Norway, Sweden and Finland.
Tipula (V.) perretti was described from single male collected in Labrador, Canada by
Hypopygium of male Tipula (Vestiplex) perretti, holotype. A Tergite 9, dorsal view; B. Left gonocoxite, outer and inner gonostyli, lateral view; B. Left outer gonostylus, lateral view; C Right outer gonostylus, lateral view; D Right inner gonostylus, lateral view; E Genital bridge, dorsal view; F Adminiculum, lateral view; G Sperm pump, dorsal view; H Distal part of aedeagus, lateral view. Abbreviations: aa, anterior apodeme; aia, anterior immovable apodeme; ca, compressor apodeme; gcx, gonocoxite; pa, posterior apodeme; pia, posterior immovable apodeme; sp1, sclerite sp1. Scale bars: a (A, C–G) = 0.5 mm, b (B) = 0.5 mm, c (H) = 0.25 mm.

We are grateful for the following Museum curators for their help and assistance for obtaining specimens: B. Sinclair and F. Brodo, CNC, Canada; J. Gelhaus, ANSP, USA.
Sabima partially financed the trip to northern Norway in 2022, which initiated this revison. Biofokus financed the revision of the Tipulomorpha material in TROM, which led to the discovery of six Norwegian specimens of T. balioptera from 1924.
The visit of P. Starkevich to CNC was supported from the European Social Fund (project No 09.3.3.-LMT-K-712-07-0103) under grant agreement with the Research Council of Lithuania (LMTLT) and visit to ANSP was supported by the Jessup Fund award.
