Material studied.
Holotype. 1 male (CUMZ-D00149-1), Thailand, Uthaithani Province , Lan-Sak District, Hub Pa Tard; 15°22'37.13"N, 99°37'49.98"E; 119 m a.s.l.; 26 July 2020; P. Pimvichai, T. Backeljau and P. Prasankok leg. GoogleMaps
Paratypes. 3 males (CUMZ-D00149-3), 3 females (CUMZ-D00149-2); same data as holotype GoogleMaps .
Etymology.
The species epithet means "friend of the dragon" and refers to the type locality, which is shared with the "shocking pink dragon millipede", Desmoxytes purpurosea Enghoff, Sutcharit & Panha, 2007.
Diagnosis.
Differing from other species in the genus by having the tip of anterior gonopod crossing over with tip of opposite side, the two together delimiting a drop-shaped “window”, whereas in the other two species the tips of anterior gonopod are separated from each other; externally differing by its bright orange color on the anterior and posterior ends. In contrast, S. constrictus gen. et sp. nov. has a row of triangular dark brown spots middorsally on its body rings, while S. prasankokae gen. et sp. nov. has a row of rectangular dark brown spots middorsally on the body rings.
Description.
Adult males with 41 or 42 podous rings, 1 apodous ring. Length ~3 cm, diameter 2.7-2.9 mm. Adult females with 41-43 podous rings, 1-3 apodous rings. Length ~3 cm, diameter 2.8-3.1 mm.
Colour. Living animal mainly dark brown. Head, dorsal part of the first four body rings and telson orange, antenna light brown, middorsal metazona orange (Fig. 6A, B View Figure 6 ).
Anterior gonopods (Fig. 3A, B, D, E View Figure 3 ) with extremely small triangular process between coxae (st), with high coxae, apically narrow, curving mesad, tip crossing over with tip of opposite side, the two together delimiting a drop-shaped “window”. Telopodite flattened apically rounded, curving backward, directed distad, as a thumb-like process (Fig. 3B View Figure 3 , arrow).
Posterior gonopods (Fig. 3C, F-K View Figure 3 ) simple, rounded, with short, smooth coxal part (pcx); telopodital part (pt) twice the length of the pcx, lateral margin folding mesad, forming a deep concavity, the inner lateral margin expanded into rounded lamella, apically forming a canopy (Fig. 3J View Figure 3 , arrow).
Female vulvae (Fig. 3L View Figure 3 ): simple, valves prominent, the right valve slightly larger than the left valve.
DNA barcode.
The GenBank accession number of the COI barcode of the paratype is OP174621 (voucher code CUMZ-D00149).
Habitat.
Found under leaf litter and on rocks.
Distribution.
Known only from the type locality in Uthaithani Province, Thailand (Fig. 7 View Figure 7 ).
