Lyrifissurae imacute.  Coxisternum: Lateral margins of rostrum and epimeres sparingly tuberculate; posteriolateral margin of epimere I in the form of an acute spur ( Fig. 9b). Anterior sternal apodeme without tubercles, almost reaching apodeme I. Apodeme II and sejugal apodeme convex, oblique to midline. Posteriomedial margin of epimeral plate I acute, that of plate II rounded. Apodeme III transverse to midline, broader than anterior apodemata, smooth on posterior margin, acute medially, connected posteriomedially by U-shaped ridge. Posterior margin of epimere IV with line of well-developed, posteriorly-directed tubercles, opposed by ridge of anteriorly-directed tubercles anterior of genital plate. Epimere IV lacking blunt, sclerotised projection laterally. Epimeral setal formula 3-1-3-5; setae all relatively short; 1aand 1bsub-equal (26–30 µm), 1cslightly longer (46 µm); 2a, 3aand 3bsub-equal (27–37 µm), 3cslightly longer (56 µm); 4a, 4c–esubequal (40–52 µm), 4bmuch shorter (21 µm). Setae 3a–con anterior margin of plate, setae 4a–eon posterior margin.  Anogenital region: Genital, anal and adanal plates surrounded by narrow zone of cuticle more heavily sclerotised than that of ventral plate ( Fig. 9b). Cuticle around genital plates with small tubercles. Each genital plate 100 µm long, 51 µm broad with six short subequal setae (9–13 µm) in median file and three longer setae in lateral file, anteriolateral seta longer (36 µm) and thicker than others (22–28 µm). Aggenital setae subequal in length to median genital setae. Pre-anal organ pointed. Each anal plate 153 µm long, 45 µm broad, with two short (18 µm) setae on central part of plate. Adanal setae ad 1spiniform, 36 µm, longer than others.  Legs: Femur I 192 µm long, with well-developed lateral projection proximally; medial projection reduced ( Fig. 34e). Cuticle with well-developed alveoli. Setae dand l" straight, stout, short (17–20 µm long), phylliform, barbed, slightly blunt apically. Seta l' longer (37 µm), phylliform, pointed and barbed apically, broadened and curved basally. Seta v' longer than others (44 µm).   Material examined.  Holotypefemale, 11 paratype females, 14 paratype males, 15 immatures(not types), CRO-003, litter under shrubs, coastal  Angophoraand  Eucalyptusforest, Quarry Beach, Mallacoota, Croajingolong National Park, Victoria, 37°35'18"S, 149°44'2"E,  20 m, coll. J.

Konwerski,  3.viii.2007.  Holotypeand paratypesdeposited in the Australian National Insect Collection, CSIROEcosystem Sciences, Canberra.   Etymology.  Phyllhermannia croajingolongensisis named for its typelocality, Croajingolong National Park.   Remarks.  Phyllhermannia croajingolongensiscan be differentiated from other member of the genus based on the following combination of characters: 1) the narrow lath connecting the median prodorsal condyles; 2) the tuberculate lateral margins of the rostrum and epimeres; 3) the curved, flattened, smooth, notogastral setae, broadened basally and pointed apically; 4) setae of epimeral plate III are on the anterior margin, those of plate IV are on the posterior margin; 5) the short, sub-equal setae of epimeral plates IV, except for 4bwhich is much shorter than the others; 6) the strongly tuberculate perigenital region; 7) genital seta g 4are longer than others in the lateral file; 8) the short, stout phylliform lateral and dorsal setae on femora I.   Phyllhermannia croajingolongensisis morphologically most similar to  P. eusetosa Lee, 1985in the relatively short setae of epimeral plates III and IV; the smooth, pointed, curved, blade-like notogastral setae and in a unique combination of characters relating to their relative positions. Setae c 1, d 1, d 2and e 1are in line with each other, the mutual distance is least between c 1, greater between d 1then d 2and most between e 2; c 3are considerably anterior (and lateral) of d 1; e 2is median (and posterior) of d 3and posterior (and lateral) of e 1and the mutual distance between f 1is half that between e 1; c2 are sub-equidistant between c 1and c 3and the distance between c 1– d 1and c 2– d 1is sub-equal.   Phyllhermannia croajingolongensisdiffers from  P. eusetosain that the lateral and dorsal setae of femora I are barbed and slightly blunt apically rather than smooth and pointed; the notogastral setae are longer and overlapping, the presence of the lath connecting the median prodorsal condyles, and a prominent inverted V-shaped interbothridial ridge and in the absence of a ridge-like structure on the anterior notogaster between setae of the cseries and seta d 1. 2007-08-03 J.
