Ugyops taranis Fennah, 1964

( Figs 5D , 6C , 7E–F , 8F–G , 11A–B , 12E–F )

Ugyops taranis is a small representative of its genus that reaches about 4–5 mm in length. It is endemic to New Caledonia ( Fennah 1964). The species was described based on two females. The male morphological features are given here for the first time, despite the fact that Fennah had access to a male from the Gressitt’s collections at a later date ( Fennah 1969). The biology of the species remains unknown.

Description of external features of U. taranis

Apical part of vertex distinctly convex ( Fig. 7E ). Discrete keel slightly convex, broadened in the apical part. Fronto-clypeal suture straight, barely visible. Labrum

relatively short ( Figs 6C , 7F ). First antennal segment relatively long, covered with long dense hair. Second antennal segment almost entirely covered with regularly distributed sensilla placoidea ( Fig. 8F ). Rather large spines and setae irregularly distributed among sensilla placoidea, numerous minute immovable tubercles visible among sensilla placoidea ( Fig. 8G ).

Ugyopini of New Caledonia with a description of Notuchus linnavuorii sp. nov. 111

Coloration of dorsal surface. Apical part of vertex with two indistinct dark spots, carinae reddish. Pronotum with two small spot in the lateral parts. Tegulae dark. Forewing longitudinal veins mostly green with short and irregularly distributed dark sections. Inner edge of clavus black for two thirds of its length and in the apical part ( Fig. 5D ).

Coloration of frons. Carinae of facies dark, areas between them with dark red longitudinal stripes, their median part pale. Carinae of clypeus reddish and areas pale ( Fig. 6C ).

Morphology of male genitalia of U. taranis

Posterior margin of pygofer straight with very deep incisions for genital styles (almost one-third the length of pygofer – Figs 12E, F ). This is distinctly different from those in U. inermis and U. nemestrinus . Anal tube relatively broad, only twice as long as wide (lateral view – Fig. 12E ). Genital styles relatively short, indistinctly broadened apically, broadly rounded and directed towards the inner side. Inner margin of genital style covered with distinct, short teeth in apical part ( Fig. 11B ). These features are also different from those in the other two species. Apexes of connective long, slender, directed towards sides in a distinct way (forming clear “T”). Stem of connective as thick as its apical processes.

Theca of aedeagus without distinct and regular lobe-like processes apically of aedeagus relatively short, less evenly bent, broadened apically with a characteristic thin spine; the spine tapering, bent towards the apex of aedeagus. Apex of aedeagus membranous, granular in structure with a single lateral spine with a subapical gonopore ( Fig. 11A ).
