Abstract: Scutigerella sinensis Jin & Bu, sp. nov. from China is described and illustrated. It is characterized by a deeply emarginated posterior margin of tergite 2, less differentiated marginal setae on all tergites, absence of seta a3 around the antennal base, and 6–8 setae on the first tergite. The complete mitochondrial genome of the new species is also analyzed and compared with the mitogenome of Scutigerella causeyae. In the reconstructed Neighbor-Joining tree based on COI gene sequences, S. sinensis sp. nov. clusters with S. causeyae, however, with big distances. The genetic divergence among S. sinensis sp. nov. and congeners, species of Hanseniella and Scutigerella, and both families of Symphyla was analyzed using COI gene sequences.

Two new species of the genus Symphylella (Symphyla, Scolopendrellidae) from China and the significance of the frons chaetotaxy https://zookeys.pensoft.net/article/96424/ ZooKeys 1138: 143-160

DOI: 10.3897/zookeys.1138.96424

Authors: Ya-Li Jin, Yun Bu

Abstract: Symphylella macrochaeta sp. nov. and Symphylella longispina sp. nov. from China are described and illustrated. Symphylella macrochaeta sp. nov. is characterized by 10 extremely long macrosetae arranged as 4/4/2 on the frons, tergites with broad triangular processes, and 4+4 setae on the first tergite. Symphylella longispina sp. nov. is characterized by a thick and prominent labrum, distinctly long proximal spines on the mandible, eight macrosetae arranged as 4/2/2 on frons, 3+3 setae on first tergite, and narrow triangular processes on the tergites. Detailed comparisons of the new species with similar species are presented. In addition, the frons chaetotaxy of Symphylella is illustrated and discussed for the first time and proposed as a significant diagnostic character for the taxonomic study of the genus.

Two new species of the genus Symphylella (Symphyla, Scolopendrellidae) from East China https://zookeys.pensoft.net/article/60210/ ZooKeys 1003: 1-18

DOI: 10.3897/zookeys.1003.60210

Authors: Ya-Li Jin, Yun Bu

Abstract: Symphylella minuta sp. nov. and Symphylella communa sp. nov. from China are described and illustrated. Symphylella minuta sp. nov. is characterized by the delicate and minute body, a well-developed and thin central rod with a vestige of a transverse suture in the middle, eight setae on the first tergite, pointed processes on the tergites, and short cerci with sparse setae. Symphylella communa sp. nov. is characterized by the chaetotaxy of the first tergite with 4+4 setae, processes of the tergites somewhat longer or the same length with broad, most of lateromaginal setae long, anterolateral setae of tergites 2–4, 6, 7, 9, and 10 distinctly longer than other lateromarginal setae, approximately as long as the process of the same tergite, and cerci with numerous subequal and slightly curved setae. In addition, the chaetotaxic variation on the tergites, the distribution, the habitat, and the feeding habit of the genus Symphylella are discussed.

Subterranean biodiversity and depth distribution of myriapods in forested scree slopes of Central Europe https://zookeys.pensoft.net/article/48914/ ZooKeys 930: 117-137

DOI: 10.3897/zookeys.930.48914

Authors: Beáta Haľková, Ivan Hadrián Tuf, Karel Tajovský, Andrej Mock

Abstract: The shallow underground of rock debris is a unique animal refuge. Nevertheless, the research of this habitat lags far behind the study of caves and soil, due to technical and time-consuming demands. Data on Myriapoda in scree habitat from eleven localities in seven different geomorphological units of the Czech and Slovak Republics were processed. Based on previous studies, as well as knowledge of cave and soil fauna, it was hypothesised that the occurrence of a varied and peculiar fauna would show a pattern of depth distribution with variations due to local specificities. From 2005–2016 (at least one year on each site), macrofauna was collected via sets of three long-term exposed subterranean traps consisting of 110 cm long perforated tube, with ten cups located in a gradient at 5–95 cm below the soil surface. In total, 14 symphylans (not identified to species level), 271 centipedes (23 spp.) and 572 millipedes (32 spp.) were sampled. The overall depth distribution of centipedes and millipedes appeared to have relatively similar pattern, with both groups being found at all depth levels. Nevertheless, this pattern depends on locations. The depth distribution trend lines are mostly in the form of an asymmetric ‘U’, with decreased abundance until the middle of the gradient, followed by increase in the deepest levels. Epigeic species were sporadically distributed along the whole depth gradient, but concentrated at the soil surface, while some subterranean species, such as the centipede Lithobius lucifugus and the millipedes Geoglomeris subterranea, Cibiniulus slovacus and Archiboreoiulus pallidus, were recorded in the deepest parts of the gradient. This characterises the debris community as a mixture of soil and subterranean species with an absence of species exclusively found in caves. The use of different fixation methods in traps had a significant and selective impact on samples; millipedes were either attracted by ethylene glycol or repelled by formaldehyde. Centipedes were also captured more frequently in ethylene glycol; however, the species composition varied in each of the fixatives. Depth distribution of myriapods was similar in both fixative solutions. Traps with these fixatives could be recommended for similar ecological studies.

Two new species of the genus Symphylella (Symphyla, Scolopendrellidae) from Tibet, China https://zookeys.pensoft.net/article/33566/ ZooKeys 845: 99-117

DOI: 10.3897/zookeys.845.33566

Authors: Ya-Li Jin, Yun Bu, Yue Jiang

Abstract: The Symphyla of Tibet are studied for the first time. Symphylella macropora sp. n. and Symphylella zhongi sp. n. from southeastern Tibet are described and illustrated. Symphylella macropora sp. n. is characterized by large, elongated oval openings of the Tömösváry organ with its inner margins covered by minute irregular teeth, rudimentary spined sensory organs present on the dorsal side of most antennal segments, and cerci with numerous long and slightly curved setae. Symphylella zhongi sp. n. is characterized by a globular Tömösváry organ with a small and roundish opening, mushroom-shaped sensory organs present on apical antennal segments, and by having tergal processes longer than their basal width with ovoid swollen ends. The newly described species are compared to the morphologically closest congeners: S. javanensis, S. asiatica, S. multisetosa, and S. simplex. A key for 43 species of the genus is also provided.

A synopsis of Estonian myriapod fauna (Myriapoda: Chilopoda, Diplopoda, Symphyla and Pauropoda) https://zookeys.pensoft.net/article/28050/ ZooKeys 793: 63-96

DOI: 10.3897/zookeys.793.28050

Authors: Kaarel Sammet, Mari Ivask, Olavi Kurina

Abstract: The data on Estonian Myriapoda are scattered in various publications and there has been no overview of the fauna up to the present. A critical summary of the previous information on Estonian Myriapoda is given, supplemented by new records and distribution maps. Altogether, 5784 specimens from 276 collecting sites were studied. To the hitherto recorded 14 centipede species are added Lithobius melanops, L. microps, Geophilus carpophagus, G. flavus, Strigamia transsilvanica and Stenotaenia linearis, a probably introduced species. Of the 27 published Estonian millipede species, the data on two species proved erroneous, and two new species were recorded (Craspedosoma raulinsii and Cylindroiulus britannicus). Two previously recorded millipede species – Brachyiulus pusillus and Mastigophorophyllon saxonicum – were not found in the recent samples, the latter may have become more rare or extinct. Pauropoda and Symphyla lack previous reliable records. Combined with published data, the number of myriapod species known from Estonia is now set at 52. Some changes in species distribution and frequencies were detected comparing the published data with new records. Some data about habitat preferences of the more common species are also given. The majority of species have a western Palaearctic distribution, while six species are at the northern limit of their ranges.

Morphological and molecular study of Symphyla from Colombia https://zookeys.pensoft.net/article/4851/ ZooKeys 484: 121-130

DOI: 10.3897/zookeys.484.8363

Authors: Diego Alberto Salazar Moncada, Jaime Calle-Osorno, Freddy Ruiz-Lopez

Abstract: The symphylans are a poorly studied group. In Colombia the number of symphylan species is unknown with only Scutigerella immaculata (Symphyla: Scutigerellidae) being reported previously. The aim of this research was to collect and identify the symphylan pests of flower crops in Colombia. Morphological descriptions showed that our specimens shared more than one of the characters that define different genera within Scutigerellidae. The COI barcode haplotype showed interspecific level genetic divergence with S. causeyae (at least 23%) and Hanseniella sp. (22%). Furthermore, our Colombian symphylans shared the same COI haplotype as some Symphyla found in Cameroon indicating a wide geographical distribution of this taxon. Our results suggest the presence of a new genus or subgenus in the class Symphyla.
