Nebularmis crebraclava ( Sun, Li & Feng, 2014) View in CoL ( Figs. 20–22, Table 10)
Material examined: Three adult females on the slide TW.008.01. One specimen was used for DNA sequencing and retrieved as a hologenophore.
Amended description: Females (i.e., from the third instar onwards; measurements and statistics in table 10): Body massive and plump ( Fig. 20), intensely red with dark red eyes; body colour and eyes dissolve in Hoyer’s medium. Large club-shaped cephalic papillae and elongated (primary) clavae ( Figs. 20, 21A View Fig , 22A View Fig ); only cirrus A present, embedded on a bulbous cirrophore ( Fig. 20A).
Dorsal plate sculpturing with evident, numerous and widely spaced roundish or polygonal epicuticular granules connected by striae of various thicknesses ( Figs. 20–21). Cephalic and cervical plates with minute granulation only ( Fig. 21A View Fig ). Large scapular plate with strongly sclerotised lateral sutures demarcating lateralmost portions characterised by minute granulation; micropores absent ( Fig. 20). Two pairs of segmental plates I–II with weakly developed smooth transverse bands; m1–2 large and unipartite, m3 greatly reduced and formed as a narrow sculptured belt adjacent to the caudal plate ( Fig. 21B–C View Fig ). Caudal plate large, with short and weakly sclerotised incisions ( Figs. 20, 21C View Fig ).
Venter weakly granulated and regularly wrinkled, as is typical for Nebularmis ( Gąsiorek et al. 2021b) ; the only areas with evident endocuticular pillars are the pair of trapezoidal subcephalic plates ( Fig. 22A–C View Fig ) and the pair of wing-shaped genital plates ( Fig. 22D View Fig ). A sexpartite gonopore placed between genital plates, and a trilobed anus between legs IV. Pedal plates I–III formed as clear aggregations of pillars in central limb portions ( Fig. 22B–C View Fig ). Pedal plates IV strongly sculptured, with pillars present also on the dentate collar ( Fig. 22D View Fig ). Pulvini absent. Spine I triangular ( Fig. 22B–C View Fig ), papilla IV small and elongated ( Figs. 20, 22D View Fig ). Claws robust, isonych/homomorphic; primary spurs present on all internal branches ( Fig. 22C–D View Fig ).
Males: Not found.
Juveniles, larvae and eggs: Not found.
Molecular markers and phylogenetic position: All five gene fragments were sequenced: 18S rRNA ( OK 048614), 28S rRNA ( OK 048632), ITS-1 ( OK 048642), ITS-2 ( OK 048623) and COI ( OK 047274). The updated phylogeny from Gąsiorek et al. (2021b) indicates the presence of sister clades in Nebularmis : one of the Oriental origin, and the second of a mixed Palaearctic and Oriental origin ( Fig. 23 View Fig ). Nebularmis crebraclava belongs to the latter clade, being the sister species of N. reticulatus .
Remarks: The newly found females supplement the original description which was based solely on males ( Sun et al. 2014).
