Hanseniella lanceolata sp.n. (Myriapoda: Symphyla) found in a European hothouse

Abstract

A new species of the symphylan genus Hanseniella Bagnall, 1913 is described. It was found in a hothouse of a small zoo at Almere, the Netherlands. Hanseniella oligomacrochaeta Scheller, 2002 was recorded, for the first time since its description, in another Dutch hothouse. A bibliographic catalogue of all 82 Hanseniella species known to date is presented. How to cite this article:

Redescription of the enigmatic myriapod Hanseniella chilensis (Hansen, 1903) (Symphyla, Scutigerellidae) based on scanning electron microscope images of Chilean specimens

“…Investigation of complete specimens of H. chilensis collected in central Chile allowed us to conclude that this species shares important morphological similarities with only one other congeneric species. Particularly, we noted that H. chilensis exhibits macrochaetae on all tergites (excluding the rudimentary first), a trait shared only with H. capensis ( Hansen 1903 ; Soesbergen 2019 ). Although it can be easily distinguished from H. capensis by the shape of the claws of the last pair of legs, as in this last species, the claws are distinctively thicker basally ( Hansen 1903 ).…”

“…Additionally, Soesbergen (2019) described in his appendix that H. arborea Scheller, 1979 possesses macrochaeta on all tergites; however, in the original description, Scheller (1979) explicitly describes that the species exhibit macrochaeta on tergites 2–4, 6, 7, 9, 10, 12, 13 and 14. This last author also mentions that the distribution of macroseta or “large setae” on the fourth and fifth podomeres of the last pair of legs is closely similar to H. chilensis , but we noted that they are remarkedly shorter in length.…”

“…Unfortunately, we were unable to compare H. chilensis with H. hardyi (Chamberlin, 1920), H. neozelandica (Chamberlin, 1920) and H. paolettii Scheller, 1993 because the number of macrochaetae present in their tergites remains unknown ( Soesbergen 2019 ). Therefore, the morphological affinity between H. chilensis and these last three species remains mostly unresolved.…”

“…In Frankrijk zijn twee soorten gemeld, beide uit de Scutigerellidae. In Kroatië en Slowakije is één soort gemeld uit de Scutigerellidae (Scheller & Stoev, 2006;Soesbergen, 2019). In België tenslotte zijn acht soorten gemeld, waarvan vijf soorten uit de Scolopendrellidae en drie uit de Scutigerellidae (Lock, 2010).…”
