(Figs. 68e, 69e, 70e, 70z, 71)
Sagola eminens Broun, 1895: 75. Raffray 1904: 497, 1911: 5, 1924: 233; Hudson 1923: 365, 1934: 183; Newton and Thayer 2005b; Nomura and Leschen 2006: 242.
Type Material. Lectotype. NEW ZEALAND: Waikato: 1♂ (BMNH), glued on rectangular card, “2724. ♂.” [white label, handwritten]; “ ♂ ” [white label, handwritten]; “ Tarukenga. ” [white label, handwritten]; “New Zealand Broun Coll. Brit. Mus. 1922–482.” [white label, printed]; “ LECTOTYPE Sagola eminens Broun Desig. Park and Carlton 2013 ” [red label, printed]. Paralectotypes (2 females). NEW ZEALAND: Bay of Plenty: 2♀♀ (BMNH), glued on rectangular card, “2724. ♀.” [white label, handwritten]; “ ♂ ” [white label, handwritten]; “ Tarukenga. ” [white label, handwritten]; “ New Zealand Broun Coll. Brit. Mus. 1922–482.” [white label, printed]; “ Sagola eminens ” [white label, handwritten]. The lectotype designation is required because Broun did not explicitly designate a type specimen, and he mentioned that three specimens were examined (Broun, 1895: 75). This designation will fix the identity of the species and facilitate its recognition by future workers.

Diagnosis. This species can be distinguished from the other species of the insignis speciesgroup by the following combination of characters: body length 2.6–2.9 mm; temporal lobe of male head distinctly projecting, exceeding eye with concave ventral surface; ventral surface of male head with transverse process behind mouthparts with three patches of dense setae medially; male elytra rectangular, female elytra subquadrate; shape of antennomeres and genitalia unique to species.
Redescription. Length 2.6–2.9 mm. Body brown, antennae, legs, maxillary palpi, and elytra paler (Fig. 68e). Head: Male head triangular, widest across temples (Fig. 68z). Female head bluntly triangular, widest across eyes. Antennomere 1 approximately 1.5 times longer than wide, 2 longer than wide, 3 subquadrate, 4–8 longer than wide, 9–10 subquadrate. Frontal sulcus deep, reaching end of eye (Fig. 68z). Anterior frontal fovea round, partially covered by frontal rostrum, posterior frontal fovea round (Fig. 68z). Eye prominent, approximately one-third length of temple (Fig. 68z). Temporal lobe of male head distinctly projecting, exceeding eye, with concave ventral surface (Fig. 69e). Ventral surface of male head with transverse process behind mouthparts with 3 patches of dense setae medially (Fig. 69e). Thorax: Prosternum as long as wide, widest at one-third length. Male elytra rectangular (Fig. 68e), female elytra subquadrate. Male meso- and metathorax trapezoidal, longer than wide, female as long as wide. Abdomen: Male tergite IV with pair of transverse patches of microtrichia reaching middle, patches absent in female. Aedeagus: Median lobe of genitalia broad with pair of triangular processes apically (Fig. 70e). Apical lobe with semicircular depression apically (Fig. 70e). Phallobase of median lobe symmetrical and rounded. Parameres symmetrical and slender, setose from midpoints to apices (Fig. 70e).
