description: 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 .................................................................... P. jeekeli Decker, sp. nov.
