description: Sagola arboricola Broun, 1921
(Figs. 41a, 41c, 41e–f, 42)
Sagola arboricola Broun, 1921a: 502. Hudson 1923: 366, 1934: 184; Newton and Thayer 2005b; Nomura and Leschen 2006: 241.
Type Material. Lectotype. NEW ZEALAND: Otago Lake: 1♀ (BMNH), glued on rectangular card, “4015. ♀ ” [white label, handwritten]; “New Zealand Broun Coll. Brit. Mus. 1922–482.” [white label, printed]; “Hollyford. 19.2.1914.” [white label, handwritten]; “ Sagola ♀ arboricola.” “LECTOTYPE Sagola arboricola Broun Desig. Park and Carlton 2013 ” [red label, printed]. Paralectotypes (n = 4: 2 males; 2 females). NEW ZEALAND: Otago Lakes: 2♂♂ 2♀♀ (BMNH), same as holotype. The lectotype designation is required because Broun did not explicitly designate a type specimen, and his comments suggest that multiple specimens were examined (Broun 1921a: 502). 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 arboricola speciesgroup by the following combination of characters: body length 2.3–2.7 mm; male antennomeres 2–10 with tubercles; ventral surface of male head with inverted triangular process bearing dense setae behind mouthparts; male abdominal ventrite VII with round depression medially; shape of genitalia unique to species.
Redescription. Length 2.3–2.7 mm. Body reddish brown, antennae, legs, maxillary palpi, and elytra paler (Fig. 41a). Head: Bluntly triangular, widest across eyes (Fig. 41e). Ventral surface of male head with inverted triangular process bearing dense setae behind mouthparts (Fig. 41f). Antennomere 1 approximately 1.5 times longer than wide, 2 longer than wide, 3 subquadrate, 4 longer than wide, 5–10 subquadrate, male 2–10 with tubercles. Frontal sulcus deep, reaching onethird length of eye (Fig. 41e). Anterior frontal fovea oval (Fig. 41e), posterior frontal fovea round (Fig. 41e). Eye large and prominent, approximately as long as temple (Fig. 41e). Thorax: Prosternum as long as wide, widest at midpoint. Elytra rectangular (Fig. 41a). Mesoand metathorax trapezoidal, longer than wide. Abdomen: Tergite IV with pair of transverse patches of microtrichia reaching middle, less developed in female. Male abdominal ventrite VII with round depression medially. Basolateral foveae of abdominal ventrites V–VI very small. Aedeagus: Median lobe triangular, dorsal process large, V-shaped (Fig. 41c). Phallobase of median lobe symmetrical and rectangular (Fig. 41c). Parameres symmetrical and rectangular with sparse setae anteriorly (Fig. 41c).
