Ramiheithrus kocinus Neboiss, 1974.

Figures 22–23

Type Material. Holotype male: Tasmania. Small creek in forest, Corinna. 5 November 1972. A. Neboiss and G. Kocins (NMV TRI-4567). 1 Paratype collected with holotype (NMV TRI-4568).

Other Material Examined. Tasmania. Creek crossing Gordon River Road. 42.887° S 146.379° E, 11 January 2012, 1 male (LTUT1103-12) (NMV TRI-54701) M. Shackleton and J. Mynott.

Diagnosis. As for the generic diagnosis with the following additions. Male genitalia with segment X median lobe broad, shorter than lateral lobes (fig. 22).

Description. Revised after Neboiss (1974). As for the generic description with the following. Type specimens blackish with faint paler irregular mottling on forewings of which the most conspicuous is a pale area covering cross veins s, r-m and m, and extending along back along M1 about half the length of the wing. Gordon River Road specimen greyish brown with indistinct white mottling and spots, forewing 9 to 9.5 mm long. R2 joining R 3 in type specimens only, fork 1 with or without a short footstalk. Forewings of male with vein A2 long in type specimens, short in Gordon River Road specimen (fig. 23).

Male genitalia. Phallus broad apically; segment X lateral lobes with a few moderately long spines medially; inferior appendages come to a slight point laterally (fig. 22).

Female, pupa and larva unknown.

Remarks. This species is known from only two specimens from the type locality and one specimen from a site (Gordon River Road) about 170 km southeast of the type locality. DNA information is only available for the southern specimen. There is some variation in wing colour and venation and male genitalia but with so few specimens available they are considered conspecific for now.
