Material examined
Holotype. One male (IEBR-Myr 673H)ı Lao Cai Prov. ı Sa Paı Hoang Lien National Parkı short bamboo forestsı Fanxifan Mt. ı 2ı800 – 2ı 900 m alt.ı 103°52 ʹ 42 ″ Eı 22°21 ʹ 22 ″ Nı 23 September 2017ı leg. Anh D. Nguyen & K. Eguchi.
Paratypes. One maleı three females (IEBR-Myr 673P)ı with the same data as the holotype.
Diagnosis
An entirely blackish or greenish-black body; ocelli 7 + 1; thoracic shield with 10 – 12 vague transverse striae (but only three cross); telopods long and robust; syncoxital lobe roundly trapeziform; both prefemoral and femoral trichosteles present; femoral process directed mesoventrallyı strongly rugulose and folded in anterior side; tip strongly recurved; posterior surface of tip densely micropapillate; tibia without modifications; tarsus curvedı bearing two apical setae.
Etymology
Named (noun in apposition) after the Fanxipan Mountain where the type specimens were found.
Description
Size. Holotype male (IEBR-Myr 673H). Width of second tergum 4.9 mm; body length 11.8 mm.
Colour. Entirely blackish or greenish-black except for two distolateral brownish-yellow marbled oval spots and lateral margins yellowish.
Head. Ocelli 7 + 1; lenses convexı shining black as background of the head. Tömösváry organs transverse ovalı ca. 2 – 2.2X wider than long. Antenna clavate apically; antennomere six largeı ca. 2.5 – 3.0X longer than wide. Antennal tip with four largeı apical sensory cones.
Body. Collum semicircuları with a very large-marbled yellowish-brown spot in the middleı and two transverse striae; other parts of collum brownish-black. Thoracic shield (= tergum 2) with a narrow hyposchismı reaching caudal margin; with 10 – 12 vague transverse striae; only 3 of which cross the dorsum. Other terga with 3 – 4 short vague transverse striae. Anal shield strongly rounded emarginate mediocaudally.
Legs. Leg-pair 17 strongly reducedı 4-segmented; coxite with a rounded outer lobeı with a setiferous tubercle distomesally; podomere 1 with a small distomesal setiferous knob. Leg-pair 18 less strongly reducedı 4-segmentedı with a simple syncoxital notch.
Genitalia ( Figures 8–10 View Figure 8 View Figure 9 View Figure 10 ). Telopods long and robust. Syncoxital lobe (syl) roundly trapeziform. Syncoxital horns (syh) highly elevatedı directed ventrallyı with numerous setae; tips truncated. Prefemur (pref) longı densely micropapillate laterally and posterolaterallyı with a longı prominentı finger-shaped trichostele (pret). Femora (fe) broadı enlarged distallyı also bearing a longı prominentı finger-shaped trichostele (fet)ı and with densely micropapillate apical cingulum. Femoral process (fp) directed mesoventrallyı strongly rugulose and folded in anterior side; tip strongly recurved; posterior surface of tip densely micropapillate. Tibia (ti) without modificationsı but the tibial process (tb) short and stout. Tarsus (ta) curvedı bearing two apical setae.
Variation. In other specimensı only 10 – 11 vague transverse striae are present on the dorsal surface of the thoracic shield. Width of second tergum 5.4 – 6.2 mm in the maleı 5.1 – 5.9 mm in the female; body length 11.0 – 11.4 mm in the maleı 12.0 – 14.0 mm in the female.
DNA barcode
COI barcode data (partial) is for the paratype uploaded to GenBank under the accession number MH248039. The new species shares the identity of 87% with Glomeris pustulata , G. connexa and G. minima .
Remarks
According to Golovatch et al. (2006) ı the new species seems to belong to the modesta - group characterised by the dark background and lighter pattern/markings. This group consists of eight speciesı mainly distributed in the Himalayas of India and Nepal. Howeverı the new species totally differs from the known modesta -group species in lacking axial spots on terga 2 – 11ı and in the presence of two distolateral brownishyellow marbled oval spots.
