Description

Holotype, male. Length , pronotum 1 elytron: 2.14 mm. Colouration. Base of elytron, legs testaceous; rostrum, apical part and pleuron of elytron darker brown; head, prothorax, pygidium greenish-bronze; sides of mesothorax, metathorax and abdomen black. Head. As in ®gure 80; short, with gena 0.77 Ö as long as width of head behind eyes; contours of genae in dorsal view parallel; vertex shining, with deep punctures densely punctate, punctures partly transversely conūent; eyes evenly rounded, dorsally approximated, separated by c. 0.28 Ö basal width of rostrum; frons as in ®gures 21±22, smooth except row of punctures along mesal margin of eye, anteriorly with median longitudinal impression, centre of frons with smooth median costa extending posteriad; ventrally in front of gular region shining, deeply punctate, without median furrow, anteriorly with short median submental carina. Rostrum 1.60 Ö as long as mouthparts, at widest point 1.52 Ö wider than at base; clypeus with median process apically deeply incised; antennal insertion at base, approximately within basal ®fth of rostrum; in lateral aspect with dorsal contour above antennal insertion weakly rounded, then in straight line to apex; ventral contour forming angle of c.140 ss with ventral contour of head, weakly convex to apex; dorsal and ventral contour converging from base to apex; ventral surface with submentum before hind level of maxillary cavities ¯at, posteriorly towards sides steeply rising to postgenal recesses, margins of ¯at median area converging basad, continued by median submental carina. Antenna as in ®gure 105. Prothorax. Sides straight , subparallel, weakly converging from base to apex; without preapical constriction; disc shining, with deep transverse anastomosing wrinkles. Elytron. At humerus simple; 2.64 Ö longer than wide; striae moderately deeply impressed. Thoracic venter. Prepectus c.as long as postpectus. Height of pterothorax 0.67 Ö length of elytron. Legs. Procoxa anteriorly simple. Profemur ventrally at middle with very weak, short, longitudinal carina. Protibia (®gure 121) with dorsal contour weakly curved, ventral contour subparallel, weakly sinuate; ventral surface anteriorly weakly granulate, posteriorly with sparse denticles, densely setose. Mesotibia with dorsal edge subapically simple, without extension. Uncus of metatibia curved ventrad, at base with posteriad directed accessory tooth. Abdomen. Ventral contour in lateral view weakly concave; venter sparsely setose; sternite VII with apex evenly concave; pygidium c. 1.44 Ö wider than long, shining, densely deeply punctate, setose, base laterally overlapped by elytral apex. Genitalia. Sternite VIII (®gure 170) with apex concave, apically setose with moderately long setae, subapically with pair of less sclerotized areas. Tegminal plate (®gure 196) with sides subparallel before apex, weakly diverging; apex subtruncate, weakly rounded, evenly setose. Aedeagus. Apical scoop of pedon (®gure 184) with lateral margins weakly convex and converging, with apex acute. TA as in ®gure 151.

Allotype, female. Same as holotype except: Length, pronotum1 elytron: 2.27 mm. Head. As in ®gure 81; eyes separated by c. 0.40 Ö basal width of rostrum. Rostrum. Apically more strongly compressed dorsoventrally; in lateral view with dorsal contour sinuate, in front of antennal insertion concave to apex. Elytron 2.54 Ö longer than wide. Thoracic venter. Height of pterothorax 0.68 Ö length of elytron. Legs. Protibia in anterior view with dorsal contour weakly curved, ventral contour strongly sinuate, convex at base, concave at apex; apex of pro-, meso- and metatibia with uncus and premucro; uncus of metatibia without accessory tooth. Abdomen. Patch of modi®ed setae c. 0.85 Ö as long as wide; sternite VI with simple row of modi®ed setae (®gure 59). Genitalia. Sternite VIII as in ®gure 220. Spermatheca (®gure 209) slender; with membranous spermathecal gland.

Intraspeci W c variation. Length, pronotum1 elytron: 2.14 ±2.31 mm (n 5 3, xÅ 5 2.24 Ô 0.09). Elytron. 2.54± 2.64 Ö longer than wide (n 5 4, xÅ 5 2.59 Ô 0.05). Abdomen. Female patch of modi®ed setae c.0.83± 0.85 Ö as long as wide (n 5 2, xÅ 5 0.84 Ö).

Etymological note This epithet is based at the type locality, the Anggi Lakes area .

Biological note

There is no record of the host of the type specimen, but Nothofagus was present at the type locality.
