( Figures 51, 52 , 54 , 60 )

Takyomyia halmaherensis Kimsey, 1996: 309 .

Tachyphron halmaherensis: Brown, 2001: 40 .

Material examined. HOLOTYPE: „. Indonesia: Halmahera : Halmahera Island , Jailolo District, Kampung Pasir Putih, 0 ° 539N, 127 ° 419E, 1–14 February 1981, A. C. Messer and P. M. Taylor, in USNM.

Distribution. Known only from Halmahera Island off the north-west coast of Irian Jaya ( Figure 60 ).

Diagnosis. Male: gena very short, less than quarter length of minimum eye diameter. Hypopygium with the apical spine long and narrow apically and broadly triangular basally, and the lateral spines long, acute and slightly divergent ( Figure 54 ). Aedeagus with apical section narrow, subparallel and sinusoidal over most of length becoming swollen apically with apex minutely spinose ( Figures 51, 52 ). Metasoma dark brown.

Description. Male: black; anterior margin of pronotum (narrowly discontinuous medially) yellow; palps pale brown; apical margin of clypeus, flagellum, tegula, legs (except coxae) and metasoma dark brown; wings hyaline, slightly infuscate apically, veins and stigma dark brown; setae white. Clypeus closely and finely punctate, apically truncate, sagittally carinate, obscurely so basally. Frons and vertex rugosely punctate. Gena finely rugosely punctate, short and subparallel, less than quarter length of minimum eye diameter. Occipital carina visible dorsally. Genal cavity not visible dorsally. Pronotum including anterior surface, mesoscutum and mesoscutellum rugosely punctate. Metanotum sparsely punctate. Propodeum and mesopleura rugosely punctate. T 1–6 sparsely and shallowly punctate, closer on T 6; T 7 closely and coarsely punctate, medially impunctate; T 1 with length: width 1.6:1. S1–8 sparsely and shallowly punctate, punctures deeper on posterior segments. Hypopygium ( Figure 54 ) subtriangular, lateral spines long, acute and slightly divergent, apical spine long and narrow and cylindrical apically, broadly triangular basally. Genitalia ( Figures 51, 52 ) with parameres with dorsal margin curved and ventral margin sinusoidal, apices narrow (in profile) and convergent, not twisted and ending at level of apex of aedeagus; basiparameres in dorsal view narrowly triangular, apex acute, ending near level of apices of cuspides, narrow in lateral view; aedeagus with distinct basal and apical sections, basal section short and bulbous without ventral lobes, apical section narrow, subparallel and sinusoidal over most of length becoming swollen with apex minutely spinose, ending near apices of parameres. BL: 8; FW: 6; HW: 4.

Remarks. The specimen labelled as the holotype by Kimsey is dated 1–14 February 1981, not 14–21 February 1991 as stated by Kimsey (1996).
