Diploechiniscus oihonnae ( Richters, 1903)

(Tables 1–3, Figs 1–7 )

Neotype locality: Norway, 62°06’02.54”N, 07°12’34.52”E, 58 m asl, Møre and Romsdal County, Stranda Municipality, Merok (now Geiranger), spruce forest, lichens on soil, September 2019, coll. Łukasz Kaczmarek.

Material examined: The 145 animals, i.e., neotype + 144 neoparatypes (females: 60; males: 35; juveniles: 20; undefined: 30) mounted on microscope slides in Hoyer’s medium, 40 animals prepared for SEM and five prepared for molecular analyses. However, the exoskeleton of a female specimen used for DNA sequences was recovered and mounted in Hoyer’s medium on a microscope slide that is included into type series.

Type depositories: Neotype (slides NOR(Merok) 2/6) and 36 neoparatypes (slides NOR(Merok) 2/6 and 2/9) are deposited at the NTNU University Museum, Department of Natural History, Erling Skakkes gt 47b, Trondheim , Norway; 40 neoparatypes (slides NOR( Merok ) 2/1, 2/2 and 2/7) are deposited at the Bohart Museum of Entomology and Nematology University of California, 1 Shields Avenue , Davis CA 95616 , USA; 68 neoparatypes (including exoskeleton after DNA extraction (slides NOR( Merok ) 2/3, 2/4, 2/5, 2/8, 2/10, 2/11, 2/12S and 2/13) are deposited at the Department of Animal Taxonomy and Ecology , Institute of Environmental Biology , Adam Mickiewicz University in Poznań , Uniwersystetu Poznańskiego 6, 61-614 Poznań , Poland.

FIGURE 1. Diploechiniscus oihonnae (neotype population); female:—habitus: A—dorso-ventral assembled image (PCM); spine on leg I (indented arrowhead), cuticular folds (empty arrows), papilla on leg IV (filled arrow) and barbed filaments (arrowheads); B—lateral view (SEM); spine on leg I (indented arrowhead), cuticular folds (empty arrows), papilla on leg IV (filled arrow) and barbed filament (arrowheads); C—dorsal view (SEM); D—head and scapular plate visible in SEM. Scale bars in micrometres [μm].

FIGURE 2. Diploechiniscus oihonnae (neotype population); female: A—lateral view with visible a small portion detached from the scapular plate (arrow), pores absent on the lateral parts of the plates (arrowhead) (PCM); B—close up of the filaments B-Bl-Bd (PCM); C—barbed cirrus E (arrowheads) (PCM); D–E—lateral view with visible papilla on leg IV (arrows), barbed filament (arrowheads), notches (filled indented arrowheads), smooth stripe without sculpture dividing paired plates into anterior and posterior part (asterisks) and anterior part of the paired plate divided into two parts (empty indented arrowhead) (PCM and SEM, respectively). Scale bars in micrometres [μm].

FIGURE 3. Diploechiniscus oihonnae (neotype population); female: A–B—a scapular plate sculpture (PCM and SEM, respectively); C– median plate 2 with absence of pores on the anterior part (arrowhead) (PCM). Scale bars in micrometres [μm].

FIGURE 4. Diploechiniscus oihonnae (neotype population); female: A–B—two ventral triangular plates below the head (PCM and SEM, respectively); C–D—two ventral triangular plates on the lateral sides of the gonopore (PCM and SEM, respectively). Scale bars in micrometres [μm].

FIGURE 5. Diploechiniscus oihonnae (neotype population); female: A–B—claws II (PCM and SEM, respectively); C–D— claws IV with small straight spurs on the external claws (arrows) (PCM and SEM, respectively). Scale bars in micrometres [μm].

FIGURE 6. Diploechiniscus oihonnae (neotype population); male: A—dorso-ventral assembled image (PCM); B—scapular plate sculpture (PCM); C—ventral view with visible plates below the head and on lateral sides of gonopore (SEM); D—two ventral triangular plates on the lateral sides of the gonopore (PCM). Scale bars in micrometres [μm].

FIGURE 7. Diploechiniscus oihonnae (neotype population); juvenile: A—lateral view (PCM); B—plates visible on the lateral sides of where the gonopore will appear after the moulting (PCM). Scale bars in micrometres [μm].
