(Not included in the key)
(Figs 297–299)
Lymaenon flagellaris Ogloblin 1959b: 61 –62. Type locality: vicinity of [San Francisco de] Quito, Pichincha, Ecuador. Gonatocerus (Gonatocerus) flagellaris (Ogloblin): De Santis 1979: 365 (catalog).
Gonatocerus flagellaris (Ogloblin): Yoshimoto 1990: 40 (list).
Lymaenon flagellaris Ogloblin: Loiácono et al. 2005: 13 (type information).
Type material examined. Holotype male [MLPA] on slide labeled: 1. “ 2000 m, Lymaenon flagellaris AO ♂ Quito, Ecuador. 25.x.1957 J. Först =N3= [all ip] – Typus –// [in India ink]”; 2. ‘3934/1”. The mounting medium on the original slide (Fig. 4) was so dark that the poorly preserved, fragmented specimen was hardly visible, so in the course of this study the holotype was remounted into Canada balsam under four coverslips, as follows: 1) head, with both scapes attached; 2) one forewing missing the very base, one complete and one incomplete hind wing (missing the basal half or so); 3) one antenna without scape; 4) fragmented body and some leg segments. The published collection dates of the holotype and the paratype (25.x.1956 and 26.xi.1956) do not entirely match the collection date on the holotype slide label. The published altitude of the collection locality was stated as 3000 m and that is probably correct, given the similar altitude of Quito (San Francisco de Quito), but it is indicated as 2000 m on the label of the holotype slide. The paratype (we assume it was a male although sex of the paratype was not mentioned in the original description), collected 26.xi. 1956 in San Mateo, Esmeraldas, Ecuador, is missing from MLPA and its whereabouts are unknown.
Redescription. MALE (holotype). Body mostly dark brown; antenna mostly brown except scape light brown; legs mostly light brown except coxae, most of metafemur, and metatibia brown. Antenna (Fig. 297) with scape smooth, short, 2.2–2.3x as long as wide (including a very short radicle); pedicel very small, F1 wider than following flagellomeres, but F2 and F3 almost as wide as F1. Mesoscutum and scutellum smooth. Propodeum (Fig. 298) with well-developed, subparallel submedian carinae extending to its anterior margin, and lateral carinae, otherwise smooth. Forewing (Fig. 299) 3.1x as long as wide (Ogloblin 1959b); longest marginal seta about 0.25x maximum wing width; disc notably infumate throughout and with a brown band from stigmal vein to posterior margin of wing, bare behind submarginal vein; cubital row of setae complete, just a few setae between it and marginal and stigmal veins, remainder of disc setose. Hind wing about 16x as long as wide; disc slightly infumate throughout, with setae mostly along margins (a few setae present in the middle of disc just beyond venation); longest marginal seta about 1.9x maximum wing width.
Measurements (µm) of the holotype. Mesosoma 492; petiole 55. Antenna: scape (including radicle) 84; pedicel 42; F1 85; F2 112; F3 106; F4 106; F5 97; F6 100; F7 94; F8 94; F9 100; F10 97; F11 112. Forewing width 347; longest marginal seta 88. Hind wing: 756:48; longest marginal seta 91.
Diagnosis. Gonatocerus (Cosmocomoidea) flagellaris is a member of the ater subgroup of the ater species group. Females are unknown, but males are characterized by the following combination: propodeum (Fig. 298) with well-developed, subparallel submedian carinae extending to anterior margin and with lateral carinae, otherwise smooth; forewing disc notably infumate throughout and with a brown band from stigmal vein to posterior margin of the wing, the cubital row of setae complete, and with just a few setae between it and the marginal and stigmal veins (Fig. 299). A matching female from or near the type locality is needed for proper recognition of this species.
Distribution. NEOTROPICAL: Ecuador.
Hosts. Unknown.
