Diagnosis.
Maximum length 57 mm. Antennae 18 articles, the basal 2.25 to 2.40 glabrous dorsally (Fig. 1C, E View Figure 1 ). With 4 or 5 teeth (rarely 3) on each tooth plate, the median 3 (or 4) ones more or less fused (Fig. 1D, E View Figure 1 ). Sternites with incomplete paramedian sutures occupying at least anterior 66 to 100% in mid and hind body region (Fig. 1G View Figure 1 ). Coxopleural process long, typically with 2 apical spines, 1-2 lateral spines and 1-2 dorsal spines (Fig. 1I View Figure 1 ). Ultimate prefemur with 4 rows of prominent spines, disposed on swollen bases (10-16 spines in total) (Fig. 1H, I View Figure 1 ).
Description
(Ar.-MHBU-SoJL1608050101). Length: 54 mm (measured from anterior margin of cephalic plate to posterior margin of tergite 21).
Pigmentation (after remaining in alcohol for five years): body color yellow-brown; legs and antennae yellow; cephalic plate, tergites 1-2, tergites 20-21 and penultimate and ultimate legs blue-green (Fig. 1A, B View Figure 1 ). Live individual (Ar.-MHBU-SoJL21080101): cephalic plate blue-green, tergites blue-brown, penultimate legs and ultimate legs yellow with blue middle part in each segment, the other legs yellow (Fig. 4C View Figure 4 ).
Cephalic plate: wider than long, rounded anteriorly, without sutures or sulci (Fig. 1C View Figure 1 ).
Antennae: 18 articles, basal 2.3 glabrous, the remainder are covered with short hairs (Fig. 1C, E View Figure 1 ).
Forcipular segment: tooth plates with 4 teeth in each plate, the median 3 fused. Process of forcipular trochanteroprefemur with 3 teeth (Fig. 1D View Figure 1 ).
Tergites (T): with complete paramedian sutures from 3 to 20, marginate from 7 to 21 (Fig. 1F View Figure 1 ). Central part of the posterior border of T21 slightly convex (Fig. 1H View Figure 1 ).
Sternites (S): smooth, with incomplete paramedian sutures from 5 to 19 (Fig. 1G View Figure 1 ); S21 with a slight median longitudinal depression and converging posteriorly (Fig. 1I View Figure 1 ).
Coxopleuron: with numerous small pores, coxopleural process moderately long and apical border with protuberance (Fig. 1I View Figure 1 ). With pore-free longitudinal strips within pore field. Coxopleural process with 2 apical spines, 2 lateral spines, and 1-2 dorsal spines.
Legs (L): L1-16 and L18-19 with 2 tarsal spurs, L1-4, left L5 and right L6 with 1 tibial spur and L1 with 1 femoral spur.
Ultimate prefemur with 4 ventro-lateral, 2 ventro-medial, 3 medial, 2 dorso-medial spines and 1 corner spine (Fig. 1H, I View Figure 1 ).
Variability.
There are multiple differences among individuals as addressed below. The number of teeth of forcipular tooth plates 4+4 (11 specimens), 5+5 (6 specimens), 3+3 (2 specimen) or 3+4 (2 specimens). Coxopleural process with 4-7 spines (2 apical spines, 1-2 lateral spines and 1-3 dorsal spines). One tibial spur on L1-4 (8 specimens), L1-5 (5 specimens), L1-2 (2 specimens), L1-3 (3 specimens), or L1-6 (2 specimens). Two tarsal spurs on 1 to 18 or 19 pairs of legs; 1 tarsal spur on subsequent to penultimate legs. Ultimate legs without tarsal spur. Ultimate legs prefemur with 11-14 spines (4 or 5 ventro-lateral, 1-3 ventro-medial, 3 or 5 medial and 1 or 2 dorso-medial and 1 corner spine, rarely 0 or 3 corner spines) (Table 1 View Table 1 ).
Habitat.
Found under stones in humid mountain bush (Fig. 4A View Figure 4 ).
Distribution.
China (Xizang) and Nepal (Fig. 5 View Figure 5 ).
