Type Material Examined. L e c t o t y p e o f Sagola rugifrons : NEW ZEALAND: Waikato: 1♂ ( BMNH), glued on rectangular card, “ Type ” [red label, printed]; “2722. ♂ ” [white label, printed]; “ Waikato ” [white label]; “New Zealand Broun Coll. Brit. Mus. 1922–482.” [white label, printed]; “ Sagola rugifrons ” [white label, handwritten]; “ LECTOTYPE Sagola rugifrons Broun Desig. Park and Carlton 2013 ” [red label, printed]. Paralectotype (1 female) . NEW ZEALAND: Waikato: 1♀ ( BMNH), glued on rectangular card, “Type” [red label, printed]; “2722. ♀ ” [white label, printed]; “ Waikato ” [white label]; “New Zealand Broun Coll. Brit. Mus. 1922–482.” [white label, printed]; “ Sagola rugifrons ” [white label, handwritten]. The lectotype designation is required because Broun did not explicitly designate a type specimen, and he mentioned that two specimens were examined ( Broun 1895: 73). This designation will fix the identity of the species and facilitate its recognition by future workers. Holotype of Sagola puncticeps : NEW ZEALAND: Coromandel : 1♂ ( BMNH), “3361. ♂ ” [white label, printed]; “New Zealand Broun Coll. Brit. Mus. 1922–482.” [white label, printed]; “Tairua. Auckland.” [white label]; “ Sagola puncticeps ” [white label, handwritten] .

Diagnosis. This species can be distinguished from the other species of the rugifrons speciesgroup by the following combination of characters: smaller body, length 2.3–2.6 mm; frontal rostrum with distinctive punctures; antennomere 1 approximately 2.5 times longer than wide, 2–8 longer than wide; posterior frontal fovea surrounded by dense setae; ventral surface of male head with weak pair of short carinae behind eyes; shape of genitalia unique to species.

Redescription. Length 2.3–2.6 mm. Body brown, antennae, legs, and maxillary palpi paler ( Fig. 8a ). Head: Round, widest across eyes ( Fig. 8a ). Frontal rostrum with distinctive punctures. Ventral surface of male head with weak pair of short carinae behind eyes. Antennomere 1 approximately 2.5 times longer than wide, 2–8 longer than wide, 9–10 subquadrate. Frontal sulcus deep and reaching midpoint of eye from frontal rostral lobes. Anterior frontal fovea oval. Posterior frontal fovea round. Male eye large and prominent, two-thirds length of temple. Female eye small one-third length of temple. Thorax: Prosternum as long as wide, widest at midpoint. Elytra rectangular in male ( Fig. 8a ), shorter in female. Hind wings welldeveloped in male, reduced to small pads in female. Meso- and metathorax trapezoidal, longer than wide. Abdomen: Male tergite IV with pair of transverse patches of microtrichia reaching middle, patches absent in female. Aedeagus: Median lobe deeply divided into 2 lobes ( Fig. 8e ). Phallobase of median lobe nearly symmetrical and rounded ( Fig. 8e ). Right paramere broader than left ( Fig. 8e ).

Type Locality. Mount Pirongia , Waikato, New Zealand .

Distribution. Auckland, Bay of Plenty, Northland, Waikato ( Fig. 9 : black circles).

Habitat. Most specimens of this species were collected in flight intercept traps and sifting leaf litter or logs in broadleaf, hardwood, Nothofagus , or podocarp forests.

Comments. Specimens of S. rugifrons can be distinguished from other species externally by the frontal rostrum with distinctive punctures; female hind wings reduced to small pads; and the female eye and antenna size and shape. The type specimens of S. puncticeps share these diagnostic characters, and this species has been collected at or near the type locality of S. rugifrons . For these reasons, we have placed this species in synonymy with S. rugifrons .
