Stephanocampta Mathot, 1966

Stephanocampta Mathot 1966: 219 –221. Type species: S. yaosekoensis Mathot , by original designation. Important subsequent reference: Huber & Lin 1999: 39–40 (diagnosis, distribution, comments).

Hadromymar Yoshimoto 1990: 30–31. Type species: H. masoni Yoshimoto, by original designation. Synonymized under Stephanocampta by Huber & Lin 1999: 39.

Diagnosis. Body length 0.3–0.65 mm. Occiput with a curved, transverse groove extending to lateral margin of head at about mid-eye height. Mandible with 1 tooth. Female funicle 7-segmented with F2 either subequal to remaining segments or ring-like; male flagellum 10-segmented with F2 ring-like. Prosternum anteriorly pointed. Scutellum without a transverse row of foveae. Fore wing relatively broad, especially towards apex, and slightly curved, with setae usually numerous on the disc; proximal macrochaeta present but distinctly shorter than distal macrochaeta. Tarsi 5-segmented. Propodeum at least half as long as scutellum, with a set of rigid translucent membranous lamellae. Petiole short, surrounded ventrally and laterally by translucent lacey collar extending out from base of gaster.

In some Madagascar species [specimens in California Academy of Sciences, San Francisco, California, and Entomology Research Museum, University of California, Riverside, California (UCRC)] the fore wing in both sexes is quite narrow with few discal setae and the male flagellum is 10-segmented with only F2 ring-like, as in Stephanocampta and also as in males of the former genus Eomymar Perkins , now considered a synonym of Camptoptera Foerster. Huber & Lin (1999) treated the former Eomymar spp. as aberrant Camptoptera Foerster and we agree. These specimens show that the limits between Camptoptera and Stephanocampta are less clear cut in some places.

Remarks. Stephanocampta can be recognized using the key in Huber & Lin (1999). In Luft Albarracin et al. (2009), it would key together at the same couplet as Camptoptera , from which it differs in having translucent, mesh-like lamellae on the propodeum.

Biology and hosts. Unknown.

Distribution. Afrotropical, Oriental, Nearctic (USA—Florida) and Neotropical (from Costa Rica south to Brazil (Huber 1999) and Argentina).
