Sejanus funerioides Schuh, 1982: 171, figs. 499, 570, 580–582 (diag., descr., disc., n. sp., diag., descr., DV, MG).
DIAGNOSIS: Recognized by relatively large size, parallel lateral hemelytral margins, castaneous coloration, two confluent reddish white spots on anterior margin of cuneus, pale antennal segment 1, tibiae, tarsi, and distal margins of femora, no visible secondary gonopore, and broad posterior process of left paramere.
DESCRIPTION: See Schuh (1984).
HOSTS: Unknown.
DISTRIBUTION: Papua New Guinea.
DISCUSSION: Sejanus funerioides superficially looks like S. funereus in overall coloration and body morphology, and shares similar morphology in the left paramere with both species having a broad posterior process (Schuh, 1982: figs. 565, 581 respectively). However, the unique apical morphology of C-shaped endosoma, with what appears to be a sclerotized flap rather than a visible secondary gonopore (Schuh 1982: fig. 580), clearly differentiates it as a distinct species within Sejanus.
