Polycentropus , new diagnostic genus cluster

Diagnosis: The representatives of the Polycentropus diagnostic genus cluster have rather complete wing venation: The forewings each have forks 1, 2, 3, 4, and 5 and hind wings each have forks 1, 2, and 5; forewings each have closed discoidal and median cells, hind wings each usually have a closed discoidal cell, but in Polycentropus both crossveins s and m are absent, leaving open discoidal and median cells in the hind wings. The primary characters for this diagnostic genus cluster are the lack of apical fork 3 in the hind wings in all species and the presence of apical fork 1 both on forewings and hind wings of most species. The gonopods are robust and broad, sometimes complex and bilobed. This diagnostic genus cluster comprises the 4 genera Polycentropus , Plectrocnemia , Holocentropus , and Polyplectropus .
