( Figs 162–167 View FIGURES 162, 163 View FIGURES 164 – 167 )

Lymaenon (Gahanopsis) deficiens Ogloblin 1946: 288   –290. Type locality: St. Augustine, Trinidad Island , Trinidad and Tobago   .

Gahanopsis deficiens (Ogloblin)   : Annecke & Doutt 1961: 13; De Santis 1979: 364 (catalog); Huber 1988: 33 (mentioned); Yoshimoto 1990: 41 (listed in membraciphagus   species group of Gonatocerus   without formal synonymy of Gahanopsis   under Gonatocerus   ).

Type material examined. Holotype female [USNM] on slide labeled: 1. “ Lymaenon (Gahanopsis) deficiens A. Ogl.   Holotypus Allotypus”; 2. “ Mymaridae   n.g. n.sp. Gahan [line] St. Augustine, Trinidad Aug. 10, 1943 E. M’C.Callan Coll. Ex. Eggs of Tylopelta monstrosa   ? Host identified by Beamer as Erechtia   sp. Lot No 43– 12051”; 3. [red] “Holo-phllo- Type No. 56877 U.S.N.M.”. The holotype (the middle female among the three females on the right side of the coverslip, marked by a smaller dot in black ink on the coverslip) is in fair condition, apparently complete, with the head mounted dorsoventrally while the rest of the body is positioned partially laterally ( Fig. 162 View FIGURES 162, 163 ). Paratypes: 6 females and 2 males (one of which, the uppermost male with its head attached to the body, is the allotype, which is marked by a larger dot in black ink on the coverslip) on the same slide and under the same coverslip as the holotype.

Material examined. COSTA RICA. GUANACASTE, La Pacífica , xii.1985, A. Forsyth (ex. Aconophora   sp.) [1 ♀, 1 ♂, UCRC]   . VENEZUELA. ZULIA, El Tucuco , 24.iv.1981, L. Masner [1 ♀, USNM]   .

Redescription. FEMALE (holotype, paratypes, and non-type specimen from Costa Rica). Body length 770–958 µm. Head and mesosoma brown to dark brown; flagellum brown; gaster light brown to brown; scape, pedicel, and legs light brown.

Antenna ( Fig. 163 View FIGURES 162, 163 ) with radicle about 0.25x total length of scape, remainder of scape about 2.4x as long as wide; pedicel much longer than F1; funicle 7-segmented; F1 the shortest funicle segment and without mps; F2–F7 more or less subequal (F2, F3, and F7 a little shorter), mps on F2 (3), F3 (3), F4 (3), F5 (3), F6 (3), and F7 (4); clava about 3.0x as long as wide, apparently with 8 mps, longer than combined length of F6 and F7.

Mesoscutum weakly sculptured, more so anteriorly; propodeum smooth. Forewing ( Fig. 162 View FIGURES 162, 163 ) 2.9–3.0x as long as wide; longest marginal seta about 0.2x maximum wing width; forewing disc with a slight brownish tinge, bare behind submarginal vein and densely setose elsewhere including behind marginal vein. Hind wing 13–14x as long as wide; longest marginal seta 1.4–1.7x maximum wing width; disc with a slight brownish tinge and setose (more sparsely behind venation). Metafemur 2.7–2.9x as long as wide.

Gaster much longer than mesosoma ( Fig. 162 View FIGURES 162, 163 ); petiole very short, strap-like, inconspicuous, ovipositor very long, projecting strongly forward under mesosoma (extending at least to the middle of mesoscutum, often as far as the middle of head) and slightly exserted beyond apex of gaster; 3.5–3.8x as long as mesotibia.

Measurements (µm) of the holotype. Total body length: 923; head: 172; mesosoma 277; gaster 584; ovipositor 750. Antenna: radicle 25; rest of scape 69; pedicel 45; F1 19; F2 40; F3 42; F4 48; F5 46; F6 48; F7 43; clava 115. Forewing 775:264; longest marginal seta 56. Hind wing 646:47; longest marginal seta 79.

MALE (allotype, the other paratype, and non-type specimen from Costa Rica). Body length 818–1064 µm. Similar to female except for normal sexually dimorphic features and the following. Antenna ( Fig. 164 View FIGURES 164 – 167 ) with scape plus radicle 2.3–2.9x as long as wide, flagellum 11-segmented. Mesosoma as in Fig. 165 View FIGURES 164 – 167 . Forewing ( Fig. 167 View FIGURES 164 – 167 ) 2.9–3.2x as long as wide. Genitalia as in Fig. 166 View FIGURES 164 – 167 .

Diagnosis. Gonatocerus (Gahanopsis) deficiens   is characterized by the following unique combination: female antenna ( Fig. 163 View FIGURES 162, 163 ) with funicle 7-segmented; F2–F7 more or less subequal in length and each with mps.

Gonatocerus (Gahanopsis) arkadak Triapitsyn   sp. n. is the only other known species of the subgenus with a 7-segmented female funicle, but F3 and F5 are short and lack mps ( Fig. 158 View FIGURES 158 – 161 ).

Distribution. NEOTROPICAL: Costa Rica *, Trinidad and Tobago, and Venezuela *. Hosts. Aconophora   sp. [new record], and Tylopelta monstrosa (Fairmaire)   ( Ogloblin 1946) ( Membracidae   ).
