Among the species with low tubercles on elytra, E. simplex is similar to E. laticeps in having lateral angles of clypeus acute and pronotal lateral margins obsolete. It can be distinguished by the frons weakly concave, frontal ridge only slightly sinuate and pronotum convex, without a medial depressed area. Description. Body length: 2.15 – 2.3 mm; body maximum width (elytra): 1.1 – 1.15 mm. Body: small, compact and distinctly convex; colour uniformly light brown; vestiture consiting of sparse, fine and short recumbent setae, longer around antennomeres III – XI. Head: surface coarsely sub-rugose; maximum width at eyes (0.68 – 0.70 mm), abruptly constricted behind eyes; frons weakly concave between eyes; frontal ridge slightly sinuate in frontal view, thicker in front of eyes above antennal insertion; clypeus narrow (ratio clypeus width/head max. width: 0.43 – 0.44), distinctly separated and with acute lateral angles; eyes small, protruding and coarsely faceted; antenna 11 -segmented with a loose and weakly developed 2 -segmented club; antennomere I thick and about twice as long as wide and about 1.5 times as long as II; I – III progressively thinner; III as long as II; IV – VIII shorter; VIII – X cupuliform; X about 1.5 times as wide as IX; XI weakly wider than X, rounded and only slightly pointed. Last maxillary palpomere flat and distinctly wide and securiform (see Fig. 6 g). Pronotum: widest at anterior third, very weakly explanate anteriorly and constricted posteriorly; surface uniformly coarsely sub-rugose, with no medial depressed area or tubercles; margins obsolete and not visible from above. Leg: simple; tarsomeres weakly transverse. Elytra: not costate, with very wide and distinct punctures (Figs 3 a, 4g) and two almost obsolete subapical tubercles on interval 3. Etymology. The name simplex is a Latin neuter adjective ( simplex = simple) and it refers to the simple dorsum that characterises this species compared to other congeners. Distribution. Tasmania (Fig. 7 f).

Nonetheless, this specimen certainly belongs to the new species E. squamosum and it is not part of the original type series of E. horridum , which consists of three specimens collected on Cradle Mountain by Lea.

Burckhardt (1, ANIC). Diagnosis. Among the species with raised tubercles on elytra, Enhypnon squamosum is distinct in having deeply denticulate pronotal margins and strongly squamiform dorsal vestiture. This species is quite variable in size and colour, from uniformly yellowish-brown to distinctly bicoloured with patterned elytra. Description. Body length: 1.9 – 3.0 mm; body maximum width (elytra): 1.0 – 1.7 mm. Body: small, compact and distinctly convex; colour from uniformly light brown to distinctly bicoloured with patterned elytra and lateral part of pronotum; vestiture consiting of dense, short and strongly squamiform setae (Figs 3 b, 4 h); long and filiform around antennomeres III – XI. Head: surface coarsely sub-rugose; maximum width at eyes (0.60 – 0.88 mm), abruptly constricted behind eyes; frons broadly concave between eyes; frontal ridge weakly sinuate in frontal view, thicker in front of eyes above antennal insertion; clypeus anteriorly curved, relatively wide (ratio clypeus width/head max. width: 0.49 – 0.58) and with obtuse lateral angles; eyes strongly protruding and coarsely faceted; antenna 11 -segmented with a loose and weakly developed 2 -segmented club; antennomere I relatively thin and elongate (about twice as long as wide); II more than twice as long as wide; II – VIII elongate and progressively shorter; IX more elongate and wider than VIII; X cupuliform and relatively narrow (less than 1.5 times as wide as IX); XI only slightly wider than X, sub-oval, weakly elongate and pointed. Last maxillary palpomere flat, distinctly wide and sub-triangular (see Fig. 6 h). Pronotum: explanate and abruptly constricted posteriorly; surface sub-rugose with two admedian shallow depressions on pronotal disc; margin denticulate, usually with four/five teeth or spines. Leg: simple; tarsomeres weakly transverse. Elytra: distinctly tuberculate along intervals 3, 5, 7, and 9; two larger sub-apical tubercles on interval 3, clearly visible in lateral view (Figs 3 b, 4 h). Etymology. The name squamosum is a Latin neuter adjective, squamosum (= that bears scales) and it refers to the distinctive vestiture, consisting of dense and strongly squamiform setae. Distribution.
