Danilo also mentioned Blandicinae - Parablandex from Madagascar could also be related - externally Dacnodes is a less good match than Cranopygia or Parablandex probably...
It is Nesolabia longicollis certainly, it has Pygidicranid-like appearance, it is endemic for Reunion
Steinmann (1990) mentions it as in a doubtful position without description, Steinmann (1986) also mentions it, for Mauritius and Réunion.
By the habitus I would expect the genus to belong to Pygidicraninae instead of Geracinae, so I will move the thread to a discussion about taxonnomic issues instead of discussions about new species
Probably genital examination, molecular barcoding and morphological examination of specimens could help here
As far as I know, no Pygidicraninae has ever been reported for Réunion On iNaturalist, 2 specimens of Dacnodes (?) sp. have been found The next species is Dacnodes malgassica from Madagascar, in Steinmanns books, only females were known, who are also apterous So it could be D. malgassica, which is further distributed or an endemic island species?
Thank you for the hint! I will delete the entry for -> Allodahlia ochroptera Brindle, 1972 – Myanmar
Eulithinus is the sister genus of Pseudochelidura or even a part of Pseudochelidura, so in the forum I will list it for Anechurinae - the status quo can be found in DSF, in the forum I want to be a step correcter/moderner when possible, even if it has been not changed officially in some cases
It's also probably a good idea to wait for the taxonomic changes in Petrs study about phylogeny. Since Anisolabididae and Spongiphoridae are highly paraphyletic, there might be a lot of changes.
This Cranopygia was found in Chongqing, Beibei, National Scenic Area of Jinyun Mountains It's not C. vitticollis and no species should occur this far north - the nearest species towards the south are for Yunnan: C. siamensis, C. proxima, C. dravida, C. modesta, C. marmoricrura and C. tonkinensis Maybe one of these
Chou (1998) lists in his species list for Taiwan Gonolabis cavaleriei (Borelli, 1921), Gonolabis formosae (Borelli, 1927) and Gonolabis marginalis (Dohrn, 1864). Taipnet (Catalogue of Life in Taiwan) lists the same species, possibly the data are exclusively from Chou (1998)
However, on iNaturalist and facebook several different Anisolabella-species have been observed. Nishikawa identified a few of them as Anisolabella ryukyuensis (Nishikawa, 1969), previously known for the Ryukyu-Islands. Petr Kočárek told me in an e-mail from the 25th November 2024, regarding Euborellia arcanum Matzke & Kočárek, 2015: "The alien occurrence of E. arcanum in Mauritius is interesting! By the way, E. arcanum is molecularly identical to A. ryukyuensis... We compared molecularly specimens collected by Masaru Nishikawa in Ryukyu many years ago, but have not synonymized it yet. But this is in the plan..." This would match expectations from Boris Eliseev and me, since on iNaturalist in East Asia many morphologically similar earwigs are observed regularly (yellow legs, very blackish, two white antennal segments, habitus etc.) and E. arcanum is distributed widely throughout the southeastern USA, probably introduced there a long time ago from East Asia and then spreaded to european greenhouses. The alien occurence on Mauritius was next to a hotel, with lot of asian tourists. Anisolabella is also known for North Africa and the Arabian Peninsula. On the other hand, Danilo Matzke told me in e-mails, that E. arcanum and A. ryukyuensis are morphologically two separate species and only the US and european specimens would match, not the east asian ones. 1st December 2024: "Aber das dauert noch ein wenig da sie sich morphologisch doch etwas unterscheiden somit nicht ganz identisch sind." and on 17th February 2025: "Das kann alles möglich sein muss man sich überraschen lassen. [...] Ja in dieser Facebookgruppe bin ich auch vertreten. ;-)) Ist ganz interessant und mit den neuesten Funden und Bildern. [...] Genau, und P. Kocarek hat die Tiere aus Florida mit den Gewächshaustieren genetisch verglichen und Bingo [...] Und die haben sich dann über Florida über den Süden der USA verbreitet und kamen dann auch nach EU. ;-)). [...] Ist schon ganz schön interessant nun muss man abwarten wie es sich weiter entwickelt."
For a comparison of some species with informations from Steinmann (1989): G. cavaleriei: 13-15,5mm, 16 antennal joints, 2 joints yellowish A. ryukyuensis: 17-22mm, 17 antennal joints, 1-4 joints whitish E. arcanum: 20-26mm, 21 antennal joints, usually 2-3 joints whitish G. formosae: 26-27,5mm, 22 antennal joints, ? A. marginalis: 17,5-30mm, 15 antennal joints, 1-4 joints whitish
To make things even more complicated, in Texas, there are very few specimens on iNat with a pronotum resembling rather Euborellia antoni (Dohrn, 1864) than Euborellia arcanum: https://www.inaturalist.org/observations/260214019 So a dispersal from the neotropics to the USA would also be possible, in this case it would be interesting to compare DNA barcodes of Euborellia antoni and Euborellia peregrina (Mjöberg, 1904) with those of Anisolabella-species of East Asia and typical Euborellia species (annulipes, annulata, femoralis, plebeja, moesta, andreinii etc.)
But in this case, those morphotypes should be collected and analyzed for potential new species, endemic to Taiwan.
1) Chelidura gansuensis (maybe still in press) 2) (Diplatys) Diplatys chowdhuryi Srivastava, 1987 is missing 3) (Diplatys) Diplatys carinatus Srivastava, 1988 is missing 4) (Diplatys) Diplatys tikadari Srivastava, 1988 is missing 5) Isolaboides immsi is still listed as Parisolabis immsi, but Srivastava (2013) mentions it as I. immsi 6) missing Anataelia troglobia Martín & Oromí, 1988 and Anataelia lavicola Martín & Oromí, 1988 7) Haplodiplatys tianpingensis Ma & Chen, 1991 is missing (ref. Fauna Sinica) 8) Haplodiplatys kurseongensis Srivastava, 1988 is missing (ref. Fauna of India) 9) indian Parisolabis 10) in Srivastava (2003) Metisolabis punctata was synonymized with Metisolabis fulgens, in DSF they're still two species. 11) Metresura flavipes is missing 12) Carcinophora joliveti & Forficula pierrei Albouy, 2002 are missing 13) Paralabella rehni 14) Pygidicrana staphylinoides
For the Euenkrates brindlei-problem, it is probably necessary to look up and compare the holotypes and museum specimens, the descriptions and then do a paper about them with suggesting a new name...much work, but maybe somebody is interested in that, we could maybe reach out to Kamimura, Nishikawa, Kocárek or somebody else
