Key to species of the genus
Pogonosternum
1. Dorsum with one median light band (
Figs 12D
,
15D
,
22D
). Femoral process 1 (
fp1
) projecting distad of lateral process (
lp
) (
Figs 13
,
16
) or femoral process 2 (
fp2
) directed proximad (
Figs 23
,
24
). ..... 2
– Dorsum with two paramedian light bands, divided by a narrow darker stripe (
Figs 8D
,
18D
). Femoral process 1 (
fp1
) not projecting distad of lateral process (
lp
) and femoral process 2 (
fp2
) small, directed distad (
Figs 9–10
) ............................................................................................................................. 4
2. Body larger: width over 3.0 mm (male) or
3.2 mm
(female). Femorite of gonopods elongate, slender. Gonopod process
fp2
(and
fp1
) long and laminate, projecting distad of
lp
(
Fig. 13
). Females with pointed process on coxa of legpair 2, reaching 3/4 of prefemur (
Fig. 5G
).
P. adrianae
Jeekel, 1982
– Body smaller: width under
2.3 mm
(male) or
2.7 mm
(female). Femorite of gonopods not particularly elongate or slender. Gonopod process
fp2
short, not projecting distad of
lp
(
Figs 16
,
23–24
). Females with rounded process on coxa of legpair 2, reaching 1/4 of prefemur (
Fig. 5H
) ............................. 3
3. Gonopod process
fp1
long, distinctly projecting distad of lateral process (
lp
) and
fp2
short, knoblike, directed proximad,
lp
directed mesad (
Fig. 16
). Male tarsal and tibial brushes present to legpair 8–12 ...........................................................................................................
P. laetificum
Jeekel, 1982
– Gonopod process
fp1
short, not projecting distad of
lp
and
fp2
slender, curved, directed proximad,
lp
directed laterad (
Figs 23
,
24
). Male tarsal and tibial brushes present to legpair 7 ..........................................................................................................
P. montanum
Decker
,
sp. nov.
4. Lateral process (
lp
) short or medium sized, not reaching or projecting distad of most distal position of prolongation of femorite (
prof
) (
Figs 9–10
). Male tarsal and tibial brushes present to legpair 7, when
prof
not elongated (
Fig. 9
A–D); sometimes present to legpair 9, when
prof
distinctly elongated and broadly curved (
Fig. 9
E–H) .........................................................
P. nigrovirgatum
(Carl, 1912)
– Lateral process (
lp
) long, nearly reaching or projecting distad of most distal position of prolongation of femorite (
prof
) (
Figs 19–20
). Male tarsal and tibial brushes always present to legpair 9,
prof
not elongated and broadly curved ....................................................................
