Pogonosternum sp. 2 – Car 2010: 320 (record). — Decker 2016a: 16 (record).
Pogonosternum sp. B – Decker 2016a: 17–25 (record, mention).
Diagnosis
Differs from other Pogonosternum species in having one lighter longitudinal stripe and no median darker stripe; from P. adrianae and P. laetificum, primarily by the proximad bending femoral process 2 (fp2) and the lateral process (lp) directed mesally, but also by the presence of a subtriangular, not pointed, process on the female leg 2 coxa; male tarsal and tibial brushes present from legpair 1 to 7; anterior spiracles obliquely ovoid with large lobiform anterodorsally extended rim and spiracular filter distinctly protruding.
Etymology
The name means “mountaineer” or “mountainous” in Latin and refers to this species’ principal occurrences at higher elevations in the Australian Alps.
Material studied

Description
MEASUREMENTS. Length ca 1.7–2.3 cm; midbody width ca 1.9–2.2 mm.
COLOURATION. Colour in fresh material (Figs 22, 26E): margin of lateral edges of collum sometimes slightly lighter. Dorsum with broad median light yellowish brown stripe. On prozonites the trapezoidal paramedian light band slightly broader anteriorly, and on metazonites slightly broader posteriorly, broadest at 1/3 of length (Figs 22D, 26E). Flanks and area around ozopores slightly lighter (Fig. 22C).
STERNITES. No conspicuous sternal cones.
LEGS. Male tarsal and tibial brushes present from legpair 1 to 7, abruptly absent after. Female coxa of legpair 2 with subtriangular process on caudal side directed distad (Fig. 34).
GONOPODS. Femorite (F) short and broad (Figs 23–24). Prolongation of femorite (prof) long, S-shaped. Femoral process 1 (fp1) laminate, long, subtriangular, slightly curved anteriad, not projecting distad of lateral process (lp) and solenomere (S). Femoral process 2 (fp2) short, slender, bent proximad. Lateral process (lp) on mesal side of prof, short, laminate, directed mesally.
SPIRACLES. Anterior spiracles obliquely ovoid. Rim raised with anterodorsal side extended, distinctly lobiform and spiracular filter twisted and protruding. Posterior spiracle ovoid with low rim and spiracular filter mostly protruding (Figs 4A, 25).
Ecology
Pogonosternum montanum Decker, sp. nov. Decker was mostly found in mountain forests from 600 to 1110 m a.s.l. It also occurs in pine plantations (Car 2010 and new collections west of Tumbarumba, New South Wales) and was collected in coastal Central Gippsland near Bruthen (AMS KS.105106), where it is possibly introduced.
Distribution
Australian Alps in far eastern Victoria and far southeastern New South Wales and adjacent regions (Fig. 7).
