Holotype. 1 male (CUMZ-D00148-1), Thailand, Lampang Province, Ngao District, Pha Thai ; 18°36'01.05"N, 99°54'01.00"E; 350 m a.s.l.; 28 July 2020; P. Pimvichai, P. Prasankok and S. Saratan leg. GoogleMaps
Paratypes. 6 females (CUMZ-D00148-2); same data as holotype GoogleMaps .
Etymology.
The species honors Associate Professor Dr. Pongpun Prasankok, biologist and devoted millipede collector.
Diagnosis.
Differing from other species in the genus by having the posterior gonopod apically with a short, sharp protrusion; externally differing by having a row of rectangular dark brown spots middorsally on the body rings.
Description.
Adult male with 41 podous rings, 1 apodous ring. Length ~3 cm, diameter ~3 mm. Adult females with 40 or 41 podous rings, 1 apodous ring. Length ~3 cm, diameter 3.2-3.6 mm.
Color of living animal: collum and telson beige; antenna and leg light brown; dorsal part of body rings yellowish brown, with a row of rectangular dark brown spots middorsally on the body rings; head and lateral part of body rings dark brown (Fig. 2I View Figure 2 , 6C, D View Figure 6 ).
Anterior gonopods (Fig. 5A, B, D, E View Figure 5 ) with high coxae, apically narrow, curving mesad, mesal margin sigmoid, posterior surface folding to cover more than half of telopodite, with strong ridge laterally. Telopodite with thick process, with strong ridge distomesally (Fig. 5B View Figure 5 , arrow).
Posterior gonopods (Fig. 5C, F-J View Figure 5 ) 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 a rounded lamella, apically forming a canopy (Fig. 5I View Figure 5 , arrow), apically with a short, sharp protrusion (Fig. 5C, G View Figure 5 , arrows).
Female vulvae (Fig. 5K View Figure 5 ): 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 OP174623 (voucher code CUMZ-D00148).
