Description. Uniformly dark brown in colour. Antennal clubs, apical 2 antennomeres (2 nd, 3 rd) white, basal antenomere (1 st) grey.

Total length: 3.4–3.5 mm. Holotype measurements: total length 3.4 mm, elytral width 2.2 mm.

Male. Head: Width to length ratio 30: 20. U-shape between clypeal teeth. Surface finely punctate, without setae. Dorsal part of eyes narrow, separated by an interocular space approximately 11–12 times eye width (23: 2).

Prothorax: Pronotum smooth, nitid, with very fine punctation towards the anterior and finely punctate posteriorly. Hypomeral surface very finely reticulate and impunctate. Hypomeral stria absent. Pronotum width to length ratio 45: 26.

Elytra: Smooth and nitid. Intervals very finely punctate and with extremely fine setae. Ratio of length of the elytra along suture to maximum elytral width 54: 58.

Legs: As per L. nitidus  species group. Ridge on ventral side of protibia apically more or less joined to the second tooth by a fine carina.

Abdomen: Rest of the pygidium surrounding central flat area is matt and reticulate with fine punctures, each with a seta.

Pterothorax: Lateral lobe of metaventrite finely punctate and setose, inner border beside mesocoxae not anteriorly widened, of same width throughout. Medial lobe of metaventrite finely punctate and without tubercle or depression.

Male genitalia: Aedeagus with left paramere excised apically.

Female. As per L. nitidus  species group. Medial lobe of metaventrite without tubercle or depression.

Etymology. The name is a noun in aposition that is formed in Kuku-Yalanji, the indigenous language of the region and refers to the place name for Cape Tribulation – Kulki, where the species occurs (see Henry & Hershberger 1986).

Distribution. Known from rainforest of the Wet Tropics (WET) IBRA bioregion [Zones 1 and 2] from Mount Finnigan to Thornton peak (~ 50 km) ( Fig. 18AView FIGURE 18). Almost all specimens have been collected at high elevations (750–1150 m). Predicted species distribution shown in Fig. 18BView FIGURE 18.

Comments. This species has been referred to to under the informal name of “ Lepanus NQ  10”, which is followed by Gunter et al. (2019). The specimen sequenced in this study was collected from Mount Finnigan and is designated as a paratype here (25-063060). Lepanus kulki  was recovered as sister to L. nitidus  in the analysis of Gunter et al. (2019) and in this study (see Fig. 1View FIGURE 1). Lepanus kulki  appears to be a generalist species that has been collected in dung or mushroom-baited pitfalls. Specimens have also been collected in flight intercept and from berlesed leaf litter.

In the elevational transect study by Monteith (1985a, 1985b) along 11 sites between sealevel and 780 m at Cape Tribulation, L. kulki  (listed as L. dichrous  in that study) was taken only at sites above 700 m.

Description. Holotype light brown with indistinct orange markings on humeral and apical areas of the elytra. Other specimens vary from a lighter brown to dark brown with orange areas more-or-less pronounced than in holotype. Antennal clubs with apical antennomere (3rd) white and basal two antennomeres (1 st, 2 nd) grey.

Total length: 4.0– 4.4 mm. Holotype measurements: total length 4.4 mm, elytral width 2.9 mm. Note the holotype is a little expanded so measurements are close approximation.

Male. Head: Width to length ratio 36: 26. Basal carina only narrowly interrupted medially. U-shaped between clypeal teeth. Surface without setae and finely punctate. Clypeal area more-or-less finely reticulate. Dorsal part of eyes moderate, separated by an interocular space approximately 9 times eye width (26: 3).

Prothorax: Pronotum smooth, nitid, with fairly uniform fine punctation, the anterior punctures not much finer than the posterior punctures. Hypomeral surface very finely reticulate and impunctate. Hypomeral stria absent. Pronotum width to length ratio 58: 35.

Elytra: Smooth and nitid. Intervals very finely punctate and with extremely fine setae. Apical area usually very finely reticulate, with stria 1 and usually stria 2 slightly impressed, appearing as a double line. Ratio of length of the elytra along suture to maximum elytral width 72: 75.

Legs: as per L. nitidus  species group. Ridge on ventral side of protibia not joined to the second tooth by a fine carina.

Abdomen: Pygidium more-or-less wholly reticulate, leaving only very narrow lateral and apical areas with fine punctures, each bearing a seta.

Pterothorax: Lateral lobe of metaventrite finely punctate, setose and more-or-less finely reticulate. Medial lobe of metaventrite finely punctate (punctures about the same size as those on lateral lobe) and more-or-less finely reticulate between metacoxae, and with a median longitudinal depression extending from metacoxae to mesocoxae.

Male genitalia: Aedeagus with apex of with left paramere entire, somewhat pointed. Apically deflexed part of right paramere angulate.

Female. as per L. nitidus  species group. Usually with a small metaventral depression and medial line between metacoxae, much smaller than in males.

Etymology. Named after the Carbine Tableland Zone of the Queensland Wet Tropics to which it is confined.

Distribution. Known from rainforest of the Wet Tropics (WET) IBRA bioregion, confined to Zone 4, Carbine Tableland, which includes Mount Lewis, Mossman Bluff, Mount Spurgeon, and Mount Perseverance ( Fig. 17AView FIGURE 17). Most specimens have been collected at high elevations (750–1250 m). Predicted species distribution as in Fig. 17BView FIGURE 17. This species is likely to represent a short-range endemic.

Comments. Lepanus carbinensis  was initially thought to have been part of Lepanus NQ  9 (= L. vangerweni  ). For this study, sequences were generated from two specimens from Mount Lewis Road that form part of the paratype series (25-053925 as COL3200 and 25-065554 as COL3201). Molecular analyses support the close relationship to L. vangerweni  but COI sequences differ by 4.9–5.1% (40–41 base pairs), congruent with inter–specific variation. Morphological differences also support the separation of the two species.

Most have been collected in flight intercept traps, while a few have been berlesed from litter or taken in pitfall traps baited with human dung, kangaroo dung or mushrooms.

Description. Holotype light brown with indistinct orange markings on humeral and apical areas of the elytra. Other specimens vary from a lighter brown to dark brown with orange areas more-or-less pronounced than in holotype. Antennal clubs with apical antennomere (3rd) white and basal two antennomeres (1 st, 2 nd) grey.

Total length: 4.0– 4.4 mm. Holotype measurements: total length 4.4 mm, elytral width 2.9 mm. Note the holotype is a little expanded so measurements are close approximation.

Male. Head: Width to length ratio 36: 26. Basal carina only narrowly interrupted medially. U-shaped between clypeal teeth. Surface without setae and finely punctate. Clypeal area more-or-less finely reticulate. Dorsal part of eyes moderate, separated by an interocular space approximately 9 times eye width (26: 3).

Prothorax: Pronotum smooth, nitid, with fairly uniform fine punctation, the anterior punctures not much finer than the posterior punctures. Hypomeral surface very finely reticulate and impunctate. Hypomeral stria absent. Pronotum width to length ratio 58: 35.

Elytra: Smooth and nitid. Intervals very finely punctate and with extremely fine setae. Apical area usually very finely reticulate, with stria 1 and usually stria 2 slightly impressed, appearing as a double line. Ratio of length of the elytra along suture to maximum elytral width 72: 75.

Legs: as per L. nitidus  species group. Ridge on ventral side of protibia not joined to the second tooth by a fine carina.

Abdomen: Pygidium more-or-less wholly reticulate, leaving only very narrow lateral and apical areas with fine punctures, each bearing a seta.

Pterothorax: Lateral lobe of metaventrite finely punctate, setose and more-or-less finely reticulate. Medial lobe of metaventrite finely punctate (punctures about the same size as those on lateral lobe) and more-or-less finely reticulate between metacoxae, and with a median longitudinal depression extending from metacoxae to mesocoxae.

Male genitalia: Aedeagus with apex of with left paramere entire, somewhat pointed. Apically deflexed part of right paramere angulate.

Female. as per L. nitidus  species group. Usually with a small metaventral depression and medial line between metacoxae, much smaller than in males.

Etymology. Named after the Carbine Tableland Zone of the Queensland Wet Tropics to which it is confined.

Distribution. Known from rainforest of the Wet Tropics (WET) IBRA bioregion, confined to Zone 4, Carbine Tableland, which includes Mount Lewis, Mossman Bluff, Mount Spurgeon, and Mount Perseverance ( Fig. 17AView FIGURE 17). Most specimens have been collected at high elevations (750–1250 m). Predicted species distribution as in Fig. 17BView FIGURE 17. This species is likely to represent a short-range endemic.

Comments. Lepanus carbinensis  was initially thought to have been part of Lepanus NQ  9 (= L. vangerweni  ). For this study, sequences were generated from two specimens from Mount Lewis Road that form part of the paratype series (25-053925 as COL3200 and 25-065554 as COL3201). Molecular analyses support the close relationship to L. vangerweni  but COI sequences differ by 4.9–5.1% (40–41 base pairs), congruent with inter–specific variation. Morphological differences also support the separation of the two species.

Most have been collected in flight intercept traps, while a few have been berlesed from litter or taken in pitfall traps baited with human dung, kangaroo dung or mushrooms.
