Stephanocampta masoni ( Yoshimoto, 1990) 

( Figs 4–11View FIGURES 4 – 7View FIGURES 8 – 11)

Hadromymar masoni  Yoshimoto 1990: 86.

Stephanocampta masoni (Yoshimoto)  : Huber & Lin 1999: 40.

Non-type material examined. Costa Rica, Heredia: Estación Biológica La Selva: 50–150 m, iv –v. 1993, P. Hanson [1 ♀, UCRC]; 10 ° 43 'N 84 °02'W, 16.viii. 1995, ALAS [1 ♀, UCRC]. 16 km SSE of La Virgen, 10 ° 16 'N 84 °05'W, 1050–1150 m, INBio-OET-ALAS Transect, ii. 2001, M. Sharkey [2 ♂, UCRC].

Taxonomic notes. Yoshimoto (1990) described S. masoni  from three females: the holotype from Costa Rica (Reserva Biológica Bosque Nuboso Monteverde, Puntarenas, 1500 m elevation), one paratype from Ecuador (Sacha [Lodge], Napo), and one paratype from Panama (15 km NW of El Hato de Volcán, Chiriquí, 1200 m elevation). The type series is deposited in the Canadian National Collection of Insects, Arachnids and Nematodes, Ottawa, Ontario, Canada ( CNC).

While sorting UCRC Neotropical specimens of Stephanocampta  , the second author of this communication noticed that more than one species appeared to be represented by specimens from Costa Rica, and that these did not appear to be conspecific with the S. masoni  paratype from Ecuador. John T. Huber ( CNC) was requested to check the type series of S. masoni  and measure the length of its holotype (indicated in the original description as 2.0 mm) and the number of funicular segments (originally described as 6 -segmented). Dr. Huber informed us that the correct body length of the holotype is 0.455 mm, that the funicle is 7 -segmented (F 2 is very short, about as long as wide). The body length of a drymounted, critical point-dried non-type female from Estación Biológica La Selva is 0.528 mm. Moreover, the female paratype from Ecuador is not a Stephanocampta  but a Camptoptera  sp. (J.T. Huber, personal communication). An antenna and a fore wing that were imaged in Yoshimoto (1990, fig. 17 and fig. 61, respectively) are mounted on a slide; these had been removed, along with one hind wing, from the paratype from Panama, which is conspecific with the holotype (J.T. Huber, pers. comm.). The specimen of S. masoni  used for the scanning electron micrograph ( Yoshimoto 1990, fig. 131) must have been yet another specimen, which was not part of the type series because it has both pairs of wings.

To facilitate recognition of S. masoni  , we illustrate both sexes based on the UCRC non-type specimens from Costa Rica. Images of the female from Estación Biológica La Selva (head: Fig. 4View FIGURES 4 – 7, antenna: Fig. 5View FIGURES 4 – 7, mesosoma and metasoma: Fig. 6View FIGURES 4 – 7, and fore and hind wings: Fig. 7View FIGURES 4 – 7) were kindly compared by Dr. Huber with the holotype and the paratype from Panama. We also provide a brief description of the male because it was unknown previously, though Huber & Lin (1999) had mentioned one undetermined male of a Stephanocampta  sp.

Description. MALE. Body length of a dry-mounted, critical point-dried specimen 0.3 mm, that of a slide-mounted specimen 0.578 mm. Head dark brown to black, rest of body dark brown; appendages light brown to brown. Antenna ( Fig. 8View FIGURES 8 – 11) with scape 5.2 × as long as wide; flagellum 10 -segmented, F 1 about 0.8 × length of F 3, F 2 ring-like (much wider than long). Mesosoma ( Fig. 9View FIGURES 8 – 11) longer than metasoma ( Fig. 10View FIGURES 8 – 11). Fore wing ( Fig. 11View FIGURES 8 – 11) 7.7 × as long as wide; hind wing ( Fig. 11View FIGURES 8 – 11) about 18 × as long as wide. Genitalia ( Fig. 10View FIGURES 8 – 11) length 60 µm.
