( Figures 3 , 23–25 , 59 ) Takyomyia sabronensis Kimsey, 1966: 310 . Tachyphron sabronensis : Brown, 2001: 40 . Material examined. HOLOTYPE : „ . Indonesia : Irian Jaya : Cyclops Mountains , Sabron , 283 m ( 930 ft ), May 1936 , L. E. Cheesman , in BMNH . Distribution. Known from the Cyclops Mountains, north-eastern Irian Jaya ( Figure 59 ). Diagnosis. Male: hypopygium with lateral margins straight and diverging posteriorly, and the apical spine broadly triangular and as long as the lateral spines. Gena less than quarter length of minimum eye diameter. Fore wing without a preapical spot. Metasoma red-brown to black, but not uniformly black. Dorsal margin of parameres slightly sinusoidal and dentate slightly before apex of basiparameres ( Figures 23, 24 ). Description. Male: black; anterior margin of pronotum (narrowly interrupted medially) and disc of metanotum yellow; metasoma red-brown to black; tegulae testaceous suffused with yellow basally; wings weakly suffused with orange with slightly darker preapical spot on fore wing; veins and stigma orange; setae white. Clypeus closely and finely punctate, apically truncate, sagittal carina obscure dorsally. Frons closely to rugosely punctate. Vertex rugosely punctate. Gena ( Figure 3 ) finely punctate, narrowly subparallel, less than quarter length of minimum eye diameter. Occipital carina visible dorsally. Genal cavity visible dorsally. Pronotum including anterior surface rugosely punctate. Mesoscutum rugosely punctate. Mesoscutellum closely punctate. Metanotum finely punctate. Propodeum closely to rugosely punctate. Mesopleura finely rugosely punctate. T 1–6 almost impunctate except posterolaterally; T 7 closely and coarsely punctate, impunctate medially; T 1 with length: width 2.0:1. S1 shallowly and sparsely punctate; S2–8 almost impunctate but becoming punctate posteriorly on posterior segments. Hypopygium ( Figure 25 ) with margins divergent posteriorly, lateral spines short, triangular and divergent, apical spine broadly triangular and as long as lateral spines. Genitalia ( Figures 23, 24 ) with parameres long, narrow and curved over most of length, dorsal margin emarginate basally, strongly emarginate near apex of basiparameres, apices strongly down-turned, narrowly rounded, divergent, ending at apex of aedeagus (when coiled); basiparameres in dorsal view subtriangular, apex emarginate and ending beyond level of apices of cuspides, broad in lateral view; aedeagus with basal and apical sections, basal section short, swollen and hoodlike with a pair of ventral lobes that originate from inside (rather than the margin of) the basal section, apical section extremely long, filamentous and coiled, much longer than length of parameres.
