(Not included in key)

( Figs 5–7 View FIGURES 5 – 7 )

Lymaenon aequatorianus Ogloblin 1959b: 58 –61. Type locality: San Mateo, Esmeraldas, Ecuador. Gonatocerus (Gonatocerus) aequatorianus (Ogloblin) : De Santis 1979: 364 (catalog).

Gonatocerus aequatorianus (Ogloblin) : Yoshimoto 1990: 39 (mistakenly listed in membraciphagus species group). Lymaenon aequatorianus Ogloblin : Loiácono et al. 2005: 12 (type information).

Type material examined. Holotype male [ MLPA] on slide labeled: 1. “ Lymaenon equatorianus A. Ogl. ♂ Holotypus Rep. Ecuador San Mateo. 19.v.56 J. Förster”; 2. ‘3932/1”. The mounting medium on the original slide ( Fig. 4 View FIGURE 4 ) was so dark that the poorly preserved, fragmented specimen was hardly visible, so we remounted the holotype in Canada balsam under four coverslips, as follows: 1) head; 2) both forewings and 1 hind wing; 3) scape, pedicel, and F1–F4 of one antenna and scape (without radicle) of the other antenna; 4) fragmented body and some leg segments.

The published collection date of the holotype (28.v.1956) contradicts the collection date on the holotype slide (19.v.1956).

Redescription. MALE (holotype). Body light brown (midlobe of mesoscutum posteriorly and along notauli, petiole, and base of gaster) to brown; scape, pedicel, and legs light brown; flagellum brown. Antenna ( Fig. 5 View FIGURES 5 – 7 ) with scape minus radicle 2.7x as long as wide. Mesoscutum and scutellum with faint sculpture. Propodeum with 2 faint submedian carinae. Forewing ( Fig. 7 View FIGURES 5 – 7 ) narrow, 4.3x as long as wide; disc slightly infumate throughout and setose behind and beyond venation, less densely so behind stigmal vein; longest marginal seta about 0.6x maximum forewing width. Hind wing about 25x as long as wide; disc slightly infumate throughout, with setae only along margins; longest marginal seta 3.6x maximum wing width. Metasoma ( Fig. 6 View FIGURES 5 – 7 ) with petiole short.

Measurements (µm) of the holotype. Mesosoma 348; petiole 27; gaster 406. Antenna: radicle 61; rest of scape 91; pedicel 51; F1 73; F2 82; F3 83; F4 82. Forewing 923:213; longest marginal seta 121. Hind wing: 745:30; longest marginal seta 109.

Diagnosis. Gonatocerus (Gonatocerus) aequatorianus , known only from the male holotype, is characterized by its light brown to brown body and narrow forewing (length:width 4.3) with uniformly infumate disc, which is sparsely setose behind the stigmal vein ( Fig. 7 View FIGURES 5 – 7 ). Until the female is identified it is impossible to properly compare G. aequatorianus with the other species and for this reason it was not included in the key.
