Four new species of the chordeumatidan millipede genus Nepalella Shear, 1979, family Megalotylidae, are described from caves in southern China: N. troglodytes sp. nov., N. lobata sp. nov., N. jinfoshan sp. nov., and N. wangi sp. nov. Three of them (except N. lobata sp. nov.) are presumed troglobites. Additional locality records of two cave congeners, N. caeca Shear, 1999 and N. grandoides Golovatch, Geoffroy & Mauriès, 2006, are also provided. DNA-barcoding based on the COI mitochondrial gene is documented in this genus and for species of the order Chordeumatida outside Europe for the first time. Interspecific p-distances between Nepalella species amount to 8.5–15.9%, while intraspecific p-distances are 0–6.8%. The species of Nepalella are found to show a surprisingly low genetic distance from the European genus Atractosoma Fanzago, 1876, family Craspedosomatidae Gray in Jones, 1843, potentially based on the very limited number of barcoding sequences of the order Chordeumatida being available.

A New Species

A new species of glomeridellid millipede is described from Guizhou Province, southern China: Tonkinomeris huzhengkunisp. nov. This new epigean species differs very clearly in many structural details, being sufficiently distinct morphologically and disjunct geographically from T. napoensis Nguyen, Sierwald & Marek, 2019, the type and sole species of Tonkinomeris Nguyen, Sierwald & Marek, 2019, which was described recently from northern Vietnam. The genus Tonkinomeris is formally relegated from Glomeridae and assigned to the family Glomeridellidae, which has hitherto been considered strictly Euro-Mediterranean in distribution and is thus new to the diplopod faunas of China and Indochina. Tonkinomeris is re-diagnosed and shown to have perhaps the basalmost position in the family Glomeridellidae. Its relationships are discussed, both morphological and zoogeographical, within and outside the Glomeridellidae, which can now be considered as relict and basically Oriental in origin. Because of the still highly limited array of DNA-barcoding sequences of the COI mitochondrial gene available in the GenBank, the first molecular phylogenetic analysis of Glomerida attempted here shows our phylogram to be too deficient to consider meaningful.

Three new species of the genus Coecobrya are described from caves in the Thai Peninsula for the first time: C. cavicta sp. nov. and C. polychaeta sp. nov. from Satun Province, and C. chumphonensis sp. nov. from Chumphon Province. These species differ in antennal length, clypeal chaetae, labial palp, sublobal chaetae of maxillary outer lobe, labial and postlabial chaetae, claw, ventral tube, manubrial plaque, and dorsal cephalic and tergal chaetotaxy. They are similar to C. annulata Zhang, Bedos & Deharveng, 2016 but differ from the latter in the combination of antennal length, claw and dorsal chaetotaxy. DNA barcoding COI sequences are provided for two species and three populations and key to the Thai species is also given. One population, which exhibits a great genetic distance (0.219–0.239) and minor but stable morphological differences from C. polychaeta sp. nov., cannot be accepted as a full species as the evidence is insufficient.

Six new species of the spider genus Tonsilla Wang & Yin, 1992 are described from southern China: T. jinyunensis sp. nov. (♂♀) from Chongqing, T. jiugongensis sp. nov. (♂♀) from Hubei, T. subtruculenta sp. nov. (♂♀), T. rutunda sp. nov. (♂♀) and T. yueliangensis sp. nov. (♂) from Guizhou and T. subrostrum sp. nov. (♂♀) from Hunan. In addition, T. yanlingensis (Zhang, Yin & Kim, 2000) is redescribed and its male is described here for the first time. Tonsilla subyanlingensis Liu & Xu, 2020 is transferred to Draconarius Ovtchinnikov, 1999, hence the new combination Draconarius subyanlingensis (Liu & Xu, 2020) comb. nov. is established. The female of T. subyanlingensis Liu & Xu, 2020 should be treated as T. yanlingensis (Zhang, Yin & Kim, 2000). Detailed descriptions, photographs of copulatory organs and somatic features, a distribution map and comparisons with closely related species are presented.

Leuctra adjariae sp. n. and Leuctra georgiae sp. n. (Plecoptera: Leuctridae) are described as two new apterous stonefly species from the Meskheti Range (Lesser Caucasus) in southwestern Georgia. Descriptions and illustrations are provided for both sexes and diagnostic characters are discussed. Males and females of the two species are associated by DNA barcodes. Comparisons with corresponding regions of COI between L. adjariae sp. n. and L. georgiae sp. n. produced K2P genetic distances of 8.38%, values well associated with interspecific variation. The well-supported monophyly as well as results of an ABGD analysis confirms the validity of both new species. Capnioneura gouanerae Vinçon & Sivec, 2011, previously described and known only from Turkey, is reported for the first time for the Caucasus.

A New Species

The genus Aspidistra is the most diverse in southern China and northern Vietnam. We describe a new species Aspidistra xuansonensis from northern Vietnam including two varieties: A. xuansonensis var. xuansonensis with greenish white perianth and A. xuansonensis var. violiflora with purple perianth. We present DNA barcoding data of plastid psbA-trnH and nuclear 5SNTS regions for these two varieties in comparison with three other species of Aspidistra. Morphology of monopodial shoots of A. xuansonensis is described in detail. A. xuansonensis resembles recently described A. lingyunensis but differs in longer leaf petioles, longer lamina, perianth tube shape (tubular, widened at the base vs. funnel-shaped), higher anther position, and pistil shape (suddenly obconic to nearly umbrella-shaped vs. obconic gradually widened to stigma).

In DNA barcoding, a short standardized DNA sequence is used to assign unknown individuals to species and aid in the discovery of new species. A fragment of the mitochondrial gene cytochrome c oxidase subunit 1 is emerging as the standard barcode region for animals. However, patterns of mitochondrial variability can be confounded by the spread of maternally transmitted bacteria that cosegregate with mitochondria. Here, we investigated the performance of barcoding in a sample comprising 12 species of the blow fly genus Protocalliphora , known to be infected with the endosymbiotic bacteria Wolbachia . We found that the barcoding approach showed very limited success: assignment of unknown individuals to species is impossible for 60% of the species, while using the technique to identify new species would underestimate the species number in the genus by 75%. This very low success of the barcoding approach is due to the non-monophyly of many of the species at the mitochondrial level. We even observed individuals from four different species with identical barcodes, which is, to our knowledge, the most extensive case of mtDNA haplotype sharing yet described. The pattern of Wolbachia infection strongly suggests that the lack of within-species monophyly results from introgressive hybridization associated with Wolbachia infection. Given that Wolbachia is known to infect between 15 and 75% of insect species, we conclude that identification at the species level based on mitochondrial sequence might not be possible for many insects. However, given that Wolbachia -associated mtDNA introgression is probably limited to very closely related species, identification at the genus level should remain possible.

Two new species of Hemileucinae are described from the region of Muzo (Boyaca department) in the Eastern Cordillera of Colombia. Leucanella bonillensis, new species, is a small greyish species whose closest relatives are L. newmani (Lemaire) and L. acutissima (Walker). It can be distinguished from those two species by several subtle differences in wing pattern and coloration as well as a few characters of the male genitalia, which are overall very conserved within the genus. Cerodirphia zulemae, new species, belongs to the very uniform species-group of C. speciosa (Cramer), characterised by a pink ground colour and the presence of a “Y”-shaped discal mark on the forewing. Based on its male genitalia, the new species is related to C. brunnea (Draudt) and C. apunctata Dias & Lemaire. It may be distinguished from the former by its more vivid ground colour, but detailed examination of the male genitalia are necessary to differentiate it from C. apunctata. Colour pictures of the habitus of the new species and their relatives are provided, and their genital structures are figured as well, including both sexes for C. zulemae. We also provide additional support to these descriptions based on genetic data obtained in the context of a global DNA barcoding campaign recently initiated for saturniid moths. Both L. bonillensis and C. zulemae are unambiguously distinguished from closest relatives based on genetic distances (no intraspecific distances in either case; interspecific distance ranges 5.6–6.6% and 6.7–12.5%, respectively) and inference of phylogenetic hypotheses based on partial sequences of the COI mitochondrial gene. These results emphasize the potential of DNA barcoding to support taxonomic work in species-groups considered difficult to address through morphology.

Recent collecting in northern Vietnam yielded specimens of several new leafhopper species, two of which represent new monotypic genera, and several additional species not previously recorded from Vietnam. The two new genera (Hochiminus n. gen. and Pseudocestius n. gen.) and 15 new species (Abrus digitatus n. sp., Aeternus ninhbinhensis n. sp., Drabescoides bispinosa n. sp., Tenompoella vietnamensis n. sp., Uzelina (Uzelina) vietnamensis sp. n., Hochiminhus tamdaoensis n. sp., Pseudocestius cucphuongensis n. sp., Phlogothamnus pseudorugosus n. sp., Scaphoidella albopunctata n. sp., Bundera onukiiformis n. sp., Carinata arcuata n. sp., Traiguma hamocauda n. sp., Signoretia tamdaoensis n. sp., Amrasca (Quartasca) curvata n. sp., Amrasca (Quartasca) excavata n. sp.) are described and illustrated and comparative notes are provided. An additional 28 species representing 20 genera are newly recorded from Vietnam. Most of the latter were previously recorded only from southern China. The enigmatic species, Tardrabassus pakneunensis Dai & Dietrich, previously known from two males collected in Laos in 1918, is newly recorded from Vietnam based on recently collected female specimens. The ovipositor structure of the female confirms placement of Tardrabassus in Iassinae. The female pregenital sternite and ovipositor of Hamulotettix ungulatus Dai & Zhang are also illustrated for the first time. A new synonymy is also proposed: Ujna consors Distant, 1908 equals Mileewa puerana Yang & Meng, 2010, n. syn.
