 Type material examined. Lymaenon fuscicornis Walker: lectotype female [MVMA], here designated to avoid ambiguity about the status of the type specimen(s) of this species, on card without an original label, labeled later: “ Anaphes fuscicornis *1 Curtis Collection”. The lectotype was initially in good condition although it is somewhat shriveled, mounted laterally, and complete (Fig. 16) but unfortunately after examining it and confirming its identity the body was accidentally destroyed when I tried to insert the very short pin into the hard bottom of the mailing box. The following appendages of the specimen remain: 1 entire antenna and F7, F8, and clava of the other antenna; 1 fore wing and apex of the other fore wing; 1 hind wing and apex of the other hind wing; 2 legs without the coxae and 1 tarsus without the basitarsus. Paralectotype: 1 complete female [MVMA] on F. Walker-style card without an original label, labeled later: “NATIONAL MUSEUM VICTORIA 50716 Anaphes fuscicornis Europe ”. The specimen actually belongs to G. litoralis.   
 Rachistus sulphuripes Foerster: lectotype female [NHMW], here designated to avoid the existing confusion regarding the status of the type specimens of this species, on slide labeled (Fig. 17): 1. [in A. Foerster’s handwriting] “ Gonatocerus sulphuripes m.”; 2. [partially in?A. Foerster’s handwriting, partially printed] “ Gon. sulphuripes Förster, Type”; 3. [printed] “Collect. G. Mayr”; 4. [W. Soyka’s slide number] “41”; 5. [red, Soyka’s label] “Holo-Type”; 6. [Soyka’s label] “ Gonatocerus Ƥ sulphuripes Förster Type”. The lectotype was poorly remounted by Soyka from a minuten pin, only several parts of the specimen remain (Fig. 18): head and mesosoma with scape, pedicel, and F1–F4 of one antenna, 1 fore wing and 2 hind wings attached; the other antenna is detached and incomplete (F8 and clava are missing). Paralectotype Ƥ [NHMW] on slide labeled: 1. “ Gon. sulphuripes Förster, Type”; 2. “Collect. G. Mayr”; 3. “42”; 4. [red] “Type”; 5. “ Gonatocerus sulphuripes Förster ”. The paralectotype is also incomplete: only head and a part of mesosoma remain, with one antenna attached (Fig. 19); detached are scape, pedicel, and F1–F3 of the other antenna and 1 fore wing (Fig. 20). Matthews (1986: 218) mentioned the holotype of Rachistus sulphuripes (on Soyka’s slide No. 41) but that was not a valid designation (Article 74.5, [ICZN] 1999) because the original description mentioned 4 female and 1 male specimens, all of which were thus syntypes.   
 Gonatocerus pictosimilis Soyka: holotype female [NHMW] on slide labeled: 1. “ Gonatocerus Ƥ pictosimilis (Soyka) Type”, 2. [red] “Type”, 3. “814”, 4. “Ramischau bei Breslau [a long illegible word] Juli 1934 lg Soyka coll. Soyka Canadabalsam”.   
 Lymaenon synaptus Debauche: holotype female [ISNB] on slide labeled: 1. “Dr. H. DEBAUCHE det. Lymaenon synaptus Deb. Ƥ Type“; 2. “Université de Louvain LAB. ENTOMOLOGIE Eegenhoven 16.V.42 – 180”. The holotype is complete, uncleared, poorly mounted more or less laterally. Paratype: allotype male [ISNB] on slide labeled: 1. “Dr. H. Debauche det. Lymaenon synaptus 1943 3 Deb. ALLO TYPE [sic, on red rectangle glued onto the label]“; 2. “Université de Louvain LAB. ENTOMOLOGIE Eegenhoven 16.V.42 – 180”.   
 Lymaenon alecto Debauche: holotype female [ISNB] on slide labeled: 1. “ Lymaenon sulphuripes alecto Deb. Ƥ TYPE [on red rectangle glued onto the label]”; 2. “Eegenhoven 4.IX.41 – n o 153 23,7/74,2”. The holotype is complete, uncleared; the body is mounted laterally separate from the head under the same coverslip. Paratypes: 1 Ƥ [ISNB] on slide labeled: 1. “Dr. H. Debauche det. Lymaenon alecto Deb. 1943 Ƥ PARA TYPE [sic, on red rectangle glued onto the label]”, 2. “Héverlé 1.VI.41 – n o 140”; 1 3 [ISNB] on slide labeled: 1. “ Lymaenon sulphuripes alecto Deb. 3 ALLO TYPE [sic, on red rectangle glued onto the label]”, 2. “Eegenhoven 4.IX.41 – n o 153”; 1 3 [ISNB] on slide labeled: 1. “Dr. H. Debauche det. Lymaenon alecto Deb. 1943 3 PARA TYPE [sic, on red rectangle glued onto the label]”, 2. “Eegenhoven 4.IX.41 – n o 154”; 1 3 [ISNB] on slide labeled: 1. “Dr. H. Debauche det. Lymaenon alecto Deb. 19.43 Ƥ PARA TYPE [sic, on red rectangle glued onto the label]”, 2. “Eegenhoven 4.IX.41 – n o 154”. Matthews (1986) was first to notice that the latter male paratype was incorrectly labeled by H.R. Debauche as a female.   
 Lymaenon crassipes Debauche: holotype female [ISNB] on slide labeled: 1. “Dr. H. Debauche det. Lymaenon crassipes Deb. 1943 Ƥ TYPE [on red rectangle glued onto the label]”; 2. “Lab. d’Entomologie de l’Université Louvain Eegenhoven 11.V.42. 177. 26 [in pencil]”. The holotype is complete, uncleared, mounted laterally. Paratypes (all on individual slides labeled “Dr. H. Debauche det. Lymaenon crassipes Deb. 1943 [respective female or male symbol] PARA TYPE [sic] (or ALLO TYPE [sic] for one male paratype) [on red rectangle glued onto the label]” on the first label, and with the heading “Lab. d’Entomologie de l’Université Louvain” on the second label), each also labeled: 1 Ƥ, “Eegenhoven 11.V.42. 178 8 [in pencil]”; 1 Ƥ, “Eegenhoven 11.V.42. 178 9 [in pencil]”; 1 3, “Eegenhoven 11.V.42. 177”; 3 3, “Eegenhoven 11.V.42. 178” (one of them is the allotype); 2 3, “Eegenhoven 16.V.42. 180”; 1 Ƥ, “Héverlé 1.VII.42. 224 12 [in pencil]”; 1 Ƥ, “Héverlé 22.VII.42.

 Redescription. FEMALE (lectotype of Lymaenon fuscicornis, lectotype and paralectotype of Rachistus sulphuripes, holotype and paratype of L. alecto, holotype and paratypes of L. crassipes, holotype of L. synaptus, and non-type specimens from Europe). Body length 730–1120 µm (dry-mounted specimens). Body normally mostly brown to dark brown except mesosoma often with some yellow or light brown and basal gastral terga light brown, occasionally mesosoma mostly yellow-orange with brown or dark brown areas; scape and pedicel light brown to brown, flagellum brown to dark brown; legs light brown to brown.   
 Antenna (Figs 18, 19, 21) with radicle 0.27–0.35× total length of scape, rest of scape 2.5–2.9× as long as wide, faintly striate; pedicel a little longer than F1; F2 longer than F1 and following funicle segments (but sometimes F2 about as long as F3); F1–F6 almost always without mps except very rarely either F3 with 1 mps (in one aberrant non-type specimen only) or F6 apparently with 1 mps on one antenna only [as in the holotype of L. synaptus which otherwise is a typical G. fuscicornis], F7 and F8 each with 2 mps; clava with 8 mps, 3.1–4.4× as long as wide, about as long as combined length of F5–F8 or slightly shorter.   
Mesosoma (Figs 18, 23). Propodeum (Fig. 22) with submedian lines more or less distinct. Fore wing (Figs 18, 20, 24) 3.6–3.8× as long as wide; longest marginal seta 0.33–0.4× maximum wing width. Fore wing disc infumate throughout, setose from about middle of submarginal vein and beyond. Hind wing (Fig. 18) 22–26× as long as wide; disc mostly bare except for rows of setae along margins and a few additional setae; longest marginal seta 3.1–3.3× maximum wing width.  
Metasoma (Fig. 23). Metasoma with petiole wider than long. Ovipositor 0.7–0.8× length of gaster, not exserted beyond its apex; ovipositor length: mesotibia length ratio 1.1–1.4:1.  
 Measurements (µm) of the lectotype of Rachistus sulphuripes. Mesosoma 462. Antenna: radicle 75; rest of scape 133; pedicel 69; F1 49; F2 69; F3 64; F4 56; F5 49; F6 46; F7 55. Fore wing: width 381; longest marginal seta 97.   
MALE (non-type specimens from Europe). Body length 630–1120 µm (dry-mounted specimens). Similar to female except for normal sexually dimorphic features and the following. Basal gastral terga sometimes a little darker than in female. Antenna (Fig. 25) with scape minus radicle 2.1–2.3× as long as wide. Fore wing (Fig. 26) 3.7–4.0× as long as wide. Genitalia as in Fig. 27.  
 Diagnosis. Gonatocerus (Gonatocerus) fuscicornis is characterized by the combination of its female antenna (Fig. 21) with mps almost always only on F7 and F8 and the fore wing disc setose from about middle of the submarginal vein (Figs 20, 24, 26).   
 The lectotype of Lymaenon fuscicornis (Fig. 16) differs in some details of coloration (particularly the legs being notably lighter) from Walker’s (1846) original description (p. 51): “Nigro-piceus, antennis pedibusque piceis” [= pitchy-black (or black with a reddish tinge), antenna and legs pitch-black], probably due to some fading of the specimen over the years.   
 Hosts. Capsus ater (Linnaeus) (Miridae) [new record]. The record of Oscinella frit (Linnaeus) (Diptera: Chloropidae) by Thompson (1958) is probably incorrect (Noyes 2012).   
 Comments. I wondered how could it happen that both Haliday (1833) and Walker (1846) failed to describe a species conspecific with G. sulphuripes, arguably the second most common European species of Gonatocerus after G. litoralis. It turned out that the long forgotten Lymaenon fuscicornis, poorly described by Walker (1846), was that species. Apparently no mymarid taxonomist had seen its type specimen(s) since J. Curtis/ A.H. Haliday/F. Walker time, and Graham (1982) did not even mention it. After reading Graham’s (1972) article about the type material of Lymaenon acuminatus Walker being discovered among the John Curtis’ specimens in MVMA, and with a similar hint from John T. Huber (CNCI), I asked Ken Walker (MVMA) to check for the type material of L. fuscicornis. He found it and sent me its digital image (Fig. 16), which I recognized as being conspecific with G. sulphuripes. Examination of the specimen, later received on loan, confirmed the conspecificity, hence the synonymy of Foerster’s species.
