Descriptions of Cubachipteria clavata View in CoL sp. nov.

( Figs 9–16 View FIGURE 9 View FIGURE 10 View FIGURES 11–12 View FIGURES 13–14 View FIGURES 15–16 )

Diagnosis. Body size: 651–671×505–518. Distal parts of lamellae with lateral tip in dorsal view. Prodorsal setae setiform, lamellar seta inserted ventrally on the lamella. Interlamellar seta thickened, not reaching distal parts of lamellae. Notogastral setae setiform, smooth. Four pairs of notogastral sacculi.

Descriptions. Measurements. Body length 671 (holotype, male), 651 (one paratype, male); body width 518 (holotype), 505 (one paratype).

Integument. Body surface shiny, colour brown. Margin of notogaster foveolate.

Prodorsum ( Figs 9–11 View FIGURE 9 View FIGURE 10 View FIGURES 11–12 ). Rostrum truncate. Lamellae broad, fused basally, distal parts of lamellae with lateral tip in dorsal view. Lamellar cusps separated anteriorly, a slit between them reaching the insertion pore of le. Rostral seta ro (94) setiform, barbed unilaterally, not visible in dorsal aspect. Lamellar seta le (79) setiform, smooth, minute, inserted ventrally on the lamella, reaching beyond the distal part of lamella. Interlamellar seta in (118) setiform, slightly barbed, not reaching distal parts of lamellae. Bothridial seta bs (97) clavate with smooth stalk and barbed head. Exobothridial seta absent. Tutoria (tu) present, reaching insertion of rostral seta, with ridge-like cusp about two-thirds length.

Notogaster ( Figs 9–11 View FIGURE 9 View FIGURE 10 View FIGURES 11–12 ). Slightly longer than wide. Process of pteromorphs long, narrowed apically, pteromorphs curved ventrally and the tip not reaching the level of insertion of lamellar setae, the tip of pteromorphs not reaching the level of insertion of rostral setae in lateral aspect view. Notogastral setae (15–20), setiform, smooth. Four pairs of sacculi are well developed. Lyrifissure im posterior to seta lm. Opisthosomal gland opening located posteriorly h 3.

Gnathosoma ( Figs 10–12 View FIGURE 10 View FIGURES 11–12 ). Subcapitulum longer than wide. Setae h (9), m (25), and a (9) setiform, smooth. Chelicera (length 218) with two barbed setae, seta cha (78) longer than chb (42). Palp (length 115) with setation 0-2-1-3-9(+1ω).

Epimeral region ( Fig. 10 View FIGURE 10 ). Epimeral setae setiform, smooth. Seta 1 b (29) longest, setae 3 b (14) and 3 c (20) medium length, other setae short (9–15). Epimeral formula 3-1-3-3.

Anogenital ( Fig. 10 View FIGURE 10 ). Six pairs of genital setae (15–26), setiform, smooth, one pair of aggenital (16), two pairs of anal (9) and three pairs of setiform, smooth adanal (11–15) setae. Lyrifissure iad located in paranal position, near to anal plates, lateral to ad 3.

Legs ( Figs 13–16 View FIGURES 13–14 View FIGURES 15–16 ).All legs monodactylous, claw thick. Famulus ɛ fine and short, near to solenidion ω 1. Solenidion ω 1 and ω 2 on tarsus I, ω 1 and ω 2 on tarsus II blunt distally. Other solenidia setiform, with thinner tips. Solenidia σ on genu curved. Seta l” on genu I and II significantly thickened, thorn-like. Genu IV curved. Formulae of leg setation and solenidia: I 1-5 -3(1)-4(2)-20(2), II 1-5 -3(1)-4(1)-15(2), III 2-3 -1(1)-3(1)-15(0), IV 2-2 -2(0)-3(1)-12(0) (see Table 1 View TABLE 1 ).

Material examined. Holotype, Gaoligong Mountain National Nature Reserve (25º18’N, 98º48’E), Yunnan Province, 20 May. 2016, Bin Li and Guoru Ren, in soil GoogleMaps . One paratype, same data as holotype. GoogleMaps

Type deposited. The holotype and one paratype are deposited in the Institute of Entomology, Guizhou University, Guiyang of China ( GUGC).

Etymology. The specific name “ clavata ” (gender feminine) is derived from the Latin “clavatus”, and refers to the clavate bothridial seta.

Remarks. The new species Cubachipteria clavata sp. nov. is morphologically most similar to Cubachipteria maxsellnicki ( Ermilov, 2016) from Venezuela in having rounded lamellae. However, the new species differs from the latter by the following characterstics: (1) seta in setiform, slightly barbed, not reaching distal parts of lamellae (vs. seta in absent in Cubachipteria maxsellnicki ); (2) seta le smooth, inserted ventrally on the lamella (vs. seta le barbed, inserted dorsally on the lamella).

Cubachipteria clavata View in CoL sp. nov. is also similar to C. gaoligongensis ( Tang, Yang & Liang 2015) View in CoL from China in having rounded lamellae. However, the new species differs from the latter by the following characterstics: (1) body length 651–671 (vs. 385–425 in C. gaoligongensis View in CoL ); (2) seta in setiform, slightly barbed, not reaching distal parts of lamellae (vs. seta in absent).
