Opisthosoma ( Fig. 2A, B ): dorsally with a broad furrow and 4 anterior projecting annuli form an arching transverse ridge, dorsum with 18 (17-19) annuli, with filamentous microtubercles except the part of the furrow; ventrally with 36 (35-38) annuli, with filamentous microtubercles; setae c2 18 (17- 20), on ventral annulus 6 (5-6), apart 63 (58-66); setae d and setae e absent; setae f 15 (14-16), on 5th ventral annulus from rear, apart 21 (19-22); setae h1 absent; setae h2 25 (22-28). Female genitalia ( Fig. 2C ) 21 (20-22) long, 24 (22-25) wide, coverflap with a middle transverse suture and many longitudinal ridges, proximal setae on coxisternum III ( 3a ) 9 (9-10), apart 18 (17-19). Male (n = 1) Body spindleform, ivory-white, 147 long, 66 wide. Gnathosoma 22, projecting obliquely down, pedipalp coxal setae ( ep ) 2; dorsal pedipalp genual setae ( d ) 6; oryal stylets 22. Prodorsal shield flat, lower than dorsal opisthosoma, with a long, thick frontal lobe; 55 long, 64 wide; shield lines bold, median line absent, admedian lines discontinuous, submedian undulated lines complete, anterior submedian lines rhomboidlike. Scapular tubercles set ahead of rear shield margin, 19 apart, scapular setae ( sc ) 3, directed up and mediad. Coxae with a sternal line, forked anteriorly and posteriorly, coxal area smooth, anterolateral setae on coxisternum I ( 1b ) 5, apart 13; proximal setae on coxisternum I ( 1a ) 9, apart 8; proximal setae on coxisternum II ( 2a ) 18, apart 24. Leg segments normal. Leg I 27, femur 8, basiventral femoral setae ( bv ) 6; genu 5, antaxial genual setae ( l’’ ) 11; tibia 6, paraxial tibial setae ( l’ ) absent; tarsus 6, paraxial fastigial tarsal setae ( ft’ ) 20, antaxial fastigial tarsal setae ( ft’’ ) 17, paraxial unguinal tarsal setae ( u’ ) 5; tarsal empodium, 5, divided, each branch 4-rayed, tarsal solenidion 6, knobbed. Leg II 25, femur 7, basiventral femoral setae ( bv ) 6; genu 4, antaxial genual setae ( l’’ ) absent; tibia 6; tarsus 6, paraxial fastigial tarsal setae ( ft’ ) 18, antaxial fastigial tarsal setae ( ft’’ ) 6, paraxial unguinal tarsal setae ( u’ ) 4; tarsal empodium, 5, divided, each branch 4-rayed, tarsal solenidion 5, knobbed. Opisthosoma: dorsally with a broad furrow and 4 anterior projecting annuli forming an arching transverse ridge, dorsum with 17 annuli, with filamentous microtubercles except the part of the furrow; ventrally with 35 annuli, with filamentous microtubercles; setae c2 16, on ventral annulus 6, apart 58; setae d and setae e absent; setae f 14, on 5th ventral annulus from rear, apart 18; setae h1 absent; setae h2 21. Male genitalia 16 wide, proximal setae on coxisternum III ( 3a ) 8; apart 15 ( Fig. 2D ). REMARKS This species is similar to Protumescoptes antidesmae Pandit & Chakrabarti, 2000 , but can be differentiated by female genitalia away from coxal base and tarsal empodium 4-rayed (female genitalia near coxal base and tarsal empodium 5-rayed in P. antidesmae ; see Pandit & Chakrabarti, 2000 ).
