Harvey& M.E. Blosfelds, T73068.  Diagnosis: Paranota very wide (midbody paranota width twice as great as ring width), metatergites with Pattern B sculpture. Gonopod telopodite with solenomere and medial process well separated, the latter expanded distally and terminating in a wide truncation, with the anterior corner produced as a small distal tooth.  Description: As for the genus. Male/female approximate measurements: length 18/ 20 mm, midbody prozonite diameter 1.5/ 1.8 mm, midbody width across paranota 3.0/ 3.2 mm. Colouring variable in alcohol, ranging from near-uniform grey-brown to medium brown with paler mottling. Antennal sockets separated by 1.5X a socket diameter. Antennae short, stouter than in other  Orthorhachis, relative lengths of antennomeres (2,6)>3>(4,5). Collum D-shaped with posterior margin slightly emarginate on either side, slightly wider than head and narrower than tergite 2. Metatergite sculpture very distinct, Pattern B ( Fig. 7A). Paranota very wide,anterior margin sloping posterolaterally to distinct corner, lateral margin more or less parallel to long axis of body; ozopore between one-half and two-thirds the length of the lateral margin ( Fig. 7A). Legs short, leg 6 tarsus 1.2X as long as femur ( Fig. 5D). Brush setae with forked tips. Gonopod aperture ovoid, wider than long, about one-third the width of the ring 7 prozonite, rim raised posterolaterally. Telopodite ( Fig. 17) short, broad at base, tapering distally; long setae on posterolateral surface to one-third telopodite height; branching beginning at two-thirds telopodite height. Solenomere a slightly tapering rod with a bluntly pointed tip, directed distally and slightly posteriorly, slightly S-shaped in lateral view (right gonopod). Medial process well-separated from solenomere, broader than solenomere at base, expanding distally and mediolaterally flattened, ending at half solenomere height in a wide truncation with a posterior corner which extends further posteriorly than solenomere in lateral view, and with a small distal tooth at anterior end of truncation.   FIGURE 17.  Orthorhachis durabilis  n. sp., male paratype, MV K-10662. (A) medial, (B) anterior, (C) lateral views of right gonopod telopodite. Setation not shown; dashed lines mark course of prostatic groove. Scale bar = 0.25 mm. Female slightly larger than male, legs not swollen. Genital aperture with posterior margin raised in slightly convex curve, bent slightly anteriorly. Cyphopods not examined.  Distribution: From near sea level to at least 1560 mover ca. 60000 km  2ineastern Victoriaand far southeastern New South Wales( Fig. 31). I have collected  O. durabilisunder loose bark on logs, in leaf litter and under pieces of rotting wood on the ground.  Etymology: Latin  durabilis, lasting, adjective, for the persistence of this species in farmed landscapes in the West Gippsland district of Victoria.  Remarks: Ignoring gonopod structure, this species would not readily be recognised as an  Orthorhachis: the tarsi are short and the paranota are remarkably wide and narrow. The gonopods, however, conform to the  Orthorhachispattern and are similar to those of  O. tallagandensisand  O. weiri, which have long tarsi and more typically shaped and sized paranota.   O. durabilisvaries little over its remarkably large range: specimens from Monga and Mt Disappointment State Forest, ca. 450 kmapart, are virtually identical. On the gonopod telopodite, there is minor variation in the depth of the branching and in the degree of overall taper. This species is unusual among southeastern Australian dalodesmids for its apparent tolerance of habitat disturbance. In Victoria, I have found it in degraded bush remnants, on roadsides and on the margins of pasture adjoining forest. 1970-05-26 R, ANIC W.
