03DE8D1BB757FFBAFF46F8E3FA1EFBB2.taxon	discussion	Remarks. Some female specimens from Finland, more or less attributable to A. subfuscus, as defined by C * ü ං ൺඉඉ ං ඇ ං (1989) and T * © ං ൺඉ ං ඍඌඒඇ (2015 b), have an mps on F 3 of at least one of the antennae and the ovipositor length: protibia length ratio of 3.5 – 4.0, thus being intermediate between A. subfuscus and A. ensifer. That may be indicative to their potential conspecificity which, however, will need to be further demonstrated by a combination of detailed morphometric and molecular studies that are beyond the scope of this communication. According to T * © ං ൺඉ ං ඍඌඒඇ (2015 b), females of the former have one mps on F 3 and the ovipositor length: protibia length ratio of 3.0 – 3.4 whereas those of the latter nominal species lack an mps on F 3 and have the ovipositor length: protibia length ratio of 3.9 – 4.0. However, presence or absence of mps on F 3 of the female antenna may vary in several other species of Anagrus (T * © ං ൺඉ ං ඍඌඒඇ 2015 b), such as A. incarnatus Haliday, 1833 (T * © ං ൺඉ ං ඍඌඒඇet al. 2018).

03DE8D1BB751FFBBFEE0FDADFDDFFB6D.taxon	discussion	Remarks. This specimen was reared from an egg of a sawfly from the Pontania dolichura species group (Hymenoptera: Tenthredinidae) on Salix glauca. Galls were collected on 6. vii. 1989 (rearing number 17 / 1989 VV). One gall contained no larva of the host, and one female mymarid emerged from the egg. It was mounted in euparal by V. Vikberg and initially identified to the former A. fuscipennis species group of Anaphes by S. V. Triapitsyn in 2017. Unfortunately, the specimen has only one complete antenna which is somewhat shriveled, so it is impossible to count mps on the funicular segments with any confidence; thus, its positive identification is impossible. Otherwise, this specimen mostly resembles those specimens of A. (Anaphes) ovipositor (Soyka, 1946) which have 1 mps on F 4 of the female antenna. It is definitely not A. (Anaphes) crassipennis (Soyka, 1946).	en	Triapitsyn, Serguei V., Koponen, Martti, Vikberg, Veli, Várkonyi, Gergely (2020): Taxonomy, annotated new records and a checklist of Mymaridae (Hymenoptera) of Finland, with description of a new species of Eustochus.

However, our discovery of two new species of Eustochus Eustochus Haliday, 1833 from Finland and Germany with an entire clava (see be- Caraphractus Walker, 1846, syn. nov., downgraded to a subgenus of low) shows that the variable segmentation of the clava in Eustochus is not a good genus-defining character, hence Remarks.

Caraphractus, with its sole valid member, the type species C. cinctus Walker, 1846 (= Eustochus (Caraphractus) cinctus (Walker, 1846), comb. nov.), is very likely essentially nothing more than just an aquatic species of Eustochus. However, while proposing this new generic synonymy, we also downgrade the taxonomic status of Caraphractus to that of a subgenus of Eustochus for the following reasons kindly provided by John T. Huber (personal communication): in female Caraphractus, mandible with 3 serrated teeth (2, not serrated teeth in most Eustochus s. str. except with 3 teeth in E. (Eustochus) koponeni); petiole ventrally with strong reticulations (smooth in most Eustochus s. str. except in E. (Eustochus) koponeni) and without a longitudinal suture (suture present at least partially in most Eustochus s. str. except in E. (Eustochus) koponeni); first gastral tergum laterally with about 10 longish setae (such setae absent in Eustochus s. str.); mps absent on funicle segments (present on several segments in Eustochus s. str.). Also, male Caraphractus have 1 less antennal flagellar segment than male Eustochus s. str., but these are known only for E. (Eustochus) atripennis (Curtis, 1832).	en	Triapitsyn, Serguei V., Koponen, Martti, Vikberg, Veli, Várkonyi, Gergely (2020): Taxonomy, annotated new records and a checklist of Mymaridae (Hymenoptera) of Finland, with description of a new species of Eustochus.

03DE8D1BB75DFFB0FCEEF964FE8FFE57.taxon	diagnosis	Diagnosis. The new taxon, which belongs to the nominotypical subgenus of Eustochus as defined here, differs from all other described Eustochus species keyed in H ඎൻൾ * © & B ൺඊඎൾ * © ඈ (2007) in having an entire clava of the female antenna. Female of E. koponeni differs from that of Eustochus (Caraphractus) cinctus (Walker, 1846), comb. nov., which also has an entire clava, in having F 1 – F 3 distinctly shorter than F 4 – F 6, each of which also with mps (Fig. 9 A); in the latter, funicle segments are subequal in length and all lack mps (T * © ං ൺඉ ං ඍඌඒඇ 2012: 22, g fi. 1). Eustochus (Eustochus) koponeni is most similar to apparently an undescribed species from Finland, known from a single female (Fig. 10 A) in VVCT (Ta: Janakkala, Raimansuo (6760: 3367), 27. vii. 2017, V. Vikberg), which was also collected at a bog. Its clava is also entire, but this Eustochus (Eustochus) sp. differs from that of E. koponeni in the following combination of features: antenna (Fig. 11 A) with scape (minus radicle) 3.2 times as long as wide; fore wing (Fig. 11 E) 3.3 times as long as wide and its longest marginal seta 0.5 times maximum wing width, hind wing (Fig. 11 E) 17.8 times as long as wide; petiole (Fig. 11 B) 1.8 times as long as wide; ovipositor short, occupying a little more than 0.5 length of gaster, and just barely exserted beyond apex of gaster (Fig. 11 D), 1.5 times length of mesotibia and 0.95 times length of metatibia. It is not described here as a new taxon because its single available specimen has just one antenna (Figs 10 A, 11 A), and also because we do not know the full range of variability of these features in E. (Eustochus) koponeni. Body and head lengths of this Eustochus (Eustochus) sp., measured prior to slide-mounting, were 1.156 mm and 0.165 mm, respectively. Its body (Fig. 10 A) and antenna are black, legs are dark brown to black except first 3 metatarsomeres are light brown, and fore wing (Fig. 11 E) disc is notably infuscate. The antenna (Fig. 11 A) has mps on F 4 – F 6 and clava. Also illustrated here, to facilitate its recognition, are its head (Fig. 10 B) and mesosoma (Fig. 11 C).	en	Triapitsyn, Serguei V., Koponen, Martti, Vikberg, Veli, Várkonyi, Gergely (2020): Taxonomy, annotated new records and a checklist of Mymaridae (Hymenoptera) of Finland, with description of a new species of Eustochus.

Unfortunately, all specimens (of both sexes, unspecified in the original description other than by their localities) of the type series of P. depressicollis, including its holotype from Parikkala, are lost from FMNH.

(Doriclytus) vitripenne by T * © ං ൺඉ ං ඍඌඒඇ & F ං ൽൺඅǤඈ (2006), so there is no doubt about its identity, and therefore no neotype designation is necessary for P. depressicollis.
