Type specimens. Holotype, F, INDONESIA: Sulawesi Utara: Bolaang Mongondow Prov., Dumoga-Bone Natl. Pk., 0° 34 ’N 123 ° 53 ’E, L. A. Durden, on passalid. Deposited in Museum Zoologicum Bogoriense, Bogor, Indonesia. Paratype, M, same data as holotype ( S 74192 View Materials ), deposited in QM.

Diagnosis. Both sexes: idiosoma 1110–1220 long; anterior hyaline projection extends well past CxI; exopodal patterning between CxII–III striped; pedofossae III present, IV absent; seta h 1 with 12 barbs; distal spine-like process on palp femur 15 long, bearing two terminal spines; both non-filamentous excrescences ribbon-like, one shorter than the other; femur III and IV with large lamellae. Female: sternal shield smooth; seta st 1 73–85 long, longer than base of tritosternum; setae st 2 –st 4 4–6 long; sternogynial shield smooth, anterior margin straight. Male: tetartosternum absent, sternal processes not articulated with sternoventral shield, symmetrical, with rounded ends, their internal margins with each with a small process; sternoventral shield (anterior of genital opening) smooth; genital opening placed between CxII–III, flanked by 6 pores.

Description. Female: Idiosoma 1110 long, 800 wide; anterior hyaline projection extends posteriorly past level of Cx IV, bears 1 pair barbed setae anteriorly, 82 long. Tritosternum base 60 long, 38 wide. Tetartosternum reticulate, crown-shaped, sternal shield smooth; st 1 6 long; st 2-4 minute. Sternogynial shield 136 long, 138 wide, smooth, slightly truncate posteriorly. Ventral shield with network of reticulation medially, lineate reticulation laterally; 1 pair of large semicircular pores posteromedially of Cx IV, 1 pair of eye-like pores, ca. 8 pairs of small round pores, and ca. 7 pairs of small (<8 long) setae. Ventrianal shield 260 long, 570 wide, with lineate reticulation, paranal setae 24 long, other setae minute; anterolateral corner of ventrianal shield not fused with ventral shield. Marginal shields with lineate reticulation. Tiny lamellae on Cx I, large lamellae on femur II–IV. Pedofossae III and CxIV-marginal suture present.

Legs. TrI with seta pv 1 not thicker than seta av 1. FeI with seta pv 3 longer and thicker than setae pv 1 and pv 2. FeII with ventral lamella, seta ad 1 barbed and thickened. GeII with seta ad 3 thickened. FeIII with small lamella distal to av 1, seta pv 1 spine-like. GeIII with seta pd 2 setiform. FeIV with lamella distal to av 1, seta pv 1 thick, spine-like, seta ad 2 thickened, seta pd 2 just distal to seta ad 2. TaII–III with seta av 2 spine-like, subequal in length to seta av 3. TaIV with seta av 2 spine-like, shorter than setiform seta av 3. Legs II–IV with setiform ad and pd setae.

Gnathosoma . Seta h 1 curved, with about 12 barbs, 70 long, distance between h 1 –h 1 8; seta h 2 barbed, 55 long; seta h 3 10 long, situated posterolaterad h 2; palpcoxal seta 20 long. Corniculi difficult to see, but appear same as other Neofedrizzia , not on tubercles. Palp, seta av 1 on trochanter with large barbs, 60 long; av 2 lightly barbed, 63 long. Palp femur with distal process 15 long, bears 2 distal spines. Chelicera, fixed digit 195 long, movable digit 43 long; fixed digit with 2 large and 2 minute teeth; excrescences consist of a large brush-like process and 2 ribbon-like processes, each with a crenate and serrated margin; both processes extend beyond end of chelicerae, but one process two-thirds length of other.

Male: Idiosoma 1220 long, 860 wide. Tritosternum base broad, 64 long, 70 wide; lateral margins with many small spines; tritosternum with supra-basal piece 28 long, 32 wide. Sternal processes undifferentiated from sternal shield, broadly connected, with small protrusions on medial edges. Sternal shield anterior of genital opening smooth. Seta st 1 laterad tiny medial protrusions, possibly broken, 12 long. Seta st 2 24 long. Genital opening 65 long, 60 wide, with 6 pores laterad the opening. Large lamellae on Cx I. Gnathosoma . Seta h 1 79 long, with about 12 barbs; h 2 broken, 53 long; h 3 13 long, posterolaterad h 1, anterior h 2. Palpcoxal seta 25 long. Anterior process of palp femur with 5 spines on right palp, 1 spine on left palp.
