Ugyops nemestrinus Fennah, 1969

( Figs 5C , 6B , 7C–D , 8C–E , 10A–B , 12C–D )

Ugyops nemestrinus is an endemic species known from New Caledonia ( Fennah 1969). In terms of body size, specimens of this species are quite large relative to other species of this genus. Its body length is about 7–9 mm. The morphological features of the male were very poorly illustrated ( Fennah 1969). Our work presents an exhaustive supplement to the aforementioned deficiencies. The biology of this species is poorly known.

Description of external features of U. nemestrinus Occiput clearly smaller than vertex ( Fig. 7C ). Frons with two distinct keels, keels slightly convex and diverge towards apex of the head. Fronto-clypeal suture distinct and slightly arcuated. Labrum slender, sharply pointed ( Figs 6B , 7D ). Second antennal segment covered with sensilla placoidea over its entire length (except for its basal part) ( Fig. 8C ). Sensilla placoidea surrounded by cuticular ridge with large spines placed vertically. Setae and rather large spines irregularly distributed among sensilla placoidea, tiny tubercles absent ( Fig. 8E ). Rostrum reaches beyond the line between hind coxae ( Fig. 8D ).

Coloration of dorsal surface. Apical part of vertex with two rather small dark spots merging with each oth- er. Pronotum and scutum with broad vertical median and reddish strip. Four irregular reddish spots at the back edge of pronotum. All pairs of legs more or less uniformly brightly colored. All longitudinal veins of forewings uniformly yellow, wing cells transparent and colorless ( Fig. 5C ).

Coloration of frons. Four carinae dark, areas among keels uniformly bright colored without patches. Carinae of clypeus dark yellow, cells between them uniformly yellow ( Fig. 6B ).

Morphology of male genitalia of U. nemestrinus Posterior margin of pygofer slightly undulating with narrow and very shallow incisions for genital styles (onetenth length of pygofer – Fig. 12C–D ); stem of stylus slightly broader than that in U. inermis . Anal tube relatively narrow, almost three times as long as wide (lateral view – Fig. 12D ). Genital styles slightly broadened and rounded apically. Apexes of genital styles narrowed, distinctly longer than those in U. inermis and bent to-

Apexes of connective short and rounded (stouter than those in U. inermis and not “Y”-shaped). Stem of connective slightly thinner than its apex. Theca of aedeagus without distinct, regular lobe-like processes apically. Aedeagus relatively short, bent elliptically, almost evenly thick along its length with a characteristic thin spine; the spine not broadened at the apex, slightly bent towards the base of aedeagus. Apex of aedeagus membranous, granular in structure without spines or processes, endowed with a subapical gonopore ( Fig. 10A ).
