( Figs 912–941 View FIGURE 912 View FIGURES 913–916 View FIGURES 917, 918 View FIGURES 919–924 View FIGURES 925–930 View FIGURES 931–936 View FIGURES 937–941 )

Stephanocampta Mathot, 1966: 219 View in CoL . Type species: Stephanocampta yaosekoensis Mathot, 1966 View in CoL , by original designation. Hadromymar Yoshimoto, 1990: 30 . Type species: Hadromymar masoni Yoshimoto, 1990 , by original designation. Synonymy

by Huber & Lin, 1999: 39.

Diagnosis. Propodeum with translucent reticulate lamina and propodeal seta lateral to spiracle ( Figs 912b View FIGURE 912 , 917 View FIGURES 917, 918 , 925–930 View FIGURES 925–930 ); gs 1 with translucent reticulate collar laterally and ventrally, concealing the petiole in lateral view ( Figs 931–936 View FIGURES 931–936 ).

Discussion. Stephanocampta belongs to the Camptoptera group of genera together with Camptoptera , Camptopteroides , Eofoersteria , Macrocamptoptera , and Ptilomymar . The peculiar translucent structures described above occur elsewhere only in Ptilomymar and a few undescribed Camptoptera in the Afrotropical region.

Important references. Huber & Lin (1999), Aquino & Triapitsyn (2014), Palanivel et al. (2015).

Remarks. Aquino & Triapitsyn (2014) recorded the genus from Florida but the specimen(s) they had were not examined by the first author so it is uncertain whether they belong to the same species as the one described below.

Diagnosis. Female. Stephanocampta xanthogaster is distinguished from all other described Stephanocampta species by the following combination: gaster mainly yellow to yellowish or light brown, contrasting distinctly with dark head and mesosoma (metasoma same colour as mesosoma in other species); fu 2 1.76× as long as wide, clava 3.77× as long as wide.

Five of the other six described species have a much longer clava than S. xanthogaster . Stephanocampta chica Aquino & Triapitsyn has a slightly shorter clava than in S. xanthogaster but fu 2 over 3× as long as wide whereas in S. xanthogaster fu 2 is less than 2× as long as wide.

Description. Body length 335–445 (n=3). Colour. Head and mesosoma dark brown to almost black; coxae brown except apex lighter; scape and pedicel basally light brown, rest of antenna brown; legs except coxae, trochanters, and sometimes base of femora, and metasoma yellow or to light brown. Head width 174 (holotype). Antenna (holotype) length/width measurements (ratios) are: scape 80/17 (4.65), pedicel 40/23 (1.71), fu 1 35/8 (4.35), fu 2 12/7 (1.76), fu 3 43/7 (6.00), fu 4 39/8 (4.85), fu 5 38/11 (3.56), fu 6 36/11 (3.37), fu 7 35/13 (2.64), clava 100/26 (3.77). Fore wing length 465, width 50, length/width 9.24, longest marginal setae 179; hind wing length 437, width 17, longest marginal setae 126. Ovipositor length ~80 (not exactly measurable) but distinctly shorter than metatibia length (177).

Male. Unknown.

Derivation of species name. The species is named after the colour of the gaster which is yellow (Greek: xanthos) to light brown.
