Description. Holotype is a teneral male, uniformly light brown in colour. One of the paratypes is also uniformly light brown while the other is dark brown. Antennal clubs grey.

Total length: 2.2–2.6 mm. Holotype measurements: total length 2.6 mm, elytral width 1.5 mm. Note: the head and pronotum of the holotype is separated from the rest of the body and carded, thus measurements are an approximation.

Male. Head. Surface with light punctation, setae absent. Basal carina absent. Dorsal part of the eyes narrow, separated by an interocular space approximately 13–14 times the eye width (68: 5); eye canthus dividing eye. Head 1.6 x wider than long (43:27).

Prothorax: Pronotal surface with very fine punctation anteriorly to fine punctation posteriorly. Anterior angles almost 90°. Basal margin slightly angulate. Hypomeral surface smooth. Hypomeral striae about half the length of the hypomeron and very close to the lateral margin almost appearing double. Pronotum 1.6 x wider than long (68:42).

Elytra: Surface smooth with lightly impressed, impunctate striae, striae 1–3 or 1–4 appearing double, striae 5–7 appearing sngle; intervals very finely punctate with very superficial setae. Stria 6 extending to elytral base and stria 7 converging towards stria 6 at the base. Stria 8 confined to groove posteriorly. Elytra 1.1 x wider than long (82:73).

Legs: Front edge of protibiae deeply angulate.

Abdomen: Pygidium simple, very finely punctate, often appearing impunctate. Abdominal ventrites reticulate right across. Ventrite 6 punctate.

Pterothorax: Medial lobe of metaventrite very finely punctate and broadly margined between the mesocoxae. Lateral lobe of metaventrite punctate, with inner border beside metacoxae anteriorly curving to meet lateral border. Mesoventrite with minute notch anteriorly. Mesoventrite smooth and nitid. Mesepimeron smooth. Metanepisternum reticulate.

Female. As per L. australis   species group.

Distribution. Known from a variety of habitats including rainforest, wet sclerophyll forest, and coastal melaleuca swamps of the Australian Wet Tropics from Cooktown to Paluma in the Australian Wet Tropics bioregion ( Fig. 6B View FIGURE 6 ). Specimens have been collected from sea-level to 900 m elevation.

Comments. The majority of specimens have been collected in flight intercept traps but some have been collect- ed in baited pitfall traps (mushroom and dung), in berlesed leaf litter and at light.A recent study on bait preference of Australian dung beetles listed L. latheticus   from kangaroo and domestic fowl dung and vertebrate and invertebrate carrion, and suggests this species is a generalist feeder ( Ebert et al. 2019).

Two specimens identified as Lepanus latheticus   were included in the phylogeny of Gunter et al. 2019, one from Paluma, which is close to the type locality (25-05320 1 specimen ♂ also as COL 2406 in ANIC), and one from Lambs Head, approximately 225 km north of the type locality (25- 063059 1 specimen ♂ in ANIC also as COL3025). These two specimens are genetically distinct, falling in two positions in the tree. The specimen from Paluma formed a relationship with an undescribed species from the L. palumensis   species group while the specimen from Lambs Head is a teneral male and was recovered sister to L. dukungarri   . Upon closer examinination, we believe the Lambs Head specimen fits more closely to L. dukungarri   than L. latheticus   . The diagnostic metafemoral expansion of L. dukungarri   is absent and the pygidium and aedeagus are missing and as such, we cannot confirm with certainty the identity of this small teneral male. Thus we have not included it as material examined for either L. dukungarri   or L. latheticus   . These two species occur in the same geographic region and can most easily be differentiated by the degree of impression of the elytral striae and male characters including the shape of the metafemora and aedeagi. Matthews (1974) designated a specimen from Boar Pocket Road, November 1969 collected by G. Brooks as part of the paratype series of L. latheticus   . This specimen (25-057919 x specimen ♂ in ANIC) is designated as a paratype of L. dukungarri   new species in this revision on the basis of diagnostic external morphology and aedeagus.
