Abstract: Type specimens of Dryinidae described by Teiso Esaki & Shiro Hashimoto are examined including recently rediscovered slide samples. Lectotypes of Apterodryinus tambiniae Esaki & Hashimoto, 1935, Echthrodelphax bicolor Esaki &Hashimoto, 1931, Pachygonatopus andoi Esaki & Hashimoto, 1935, Pseudogonatopus flavifemur Esaki & Hashimoto, 1932
are designated. Redescriptions are provided based on rediscovered types. Tetrodontochelys lucens Olmi, 1984 (= Gonatopus
lucens) is regarded as a junior synonym of P. andoi.
Key Word: parasitoid wasp; synonymy; type designation

Introduction
In the 1930’s, Dr. Teiso Esaki and Mr. Shiro Hashimoto described nine species of Dryinidae (Hymenoptera: Chrysidoidea) as
natural enemies of rice planthoppers and leafhoppers (Esaki & Hashimoto, 1931, 1932, 1933, 1935). Their dryinid types recognizedin the 1980’s were studied and some name-bearing types were considered to be lost (Olmi, 1984). Because the original description
by Esaki & Hashimoto is insufficient to identify the species, the taxonomic status of the species without type specimens has been
uncertain (Olmi, 1984; Xu et al., 2013; Olmi & Xu, 2015; Mita & Olmi, 2013; Mita et al., 2017). Only one species from uncertain
taxa, Apterodryinus tambiniae Esaki & Hashimoto, 1935 (= Gonatopus tambiniae), was confirmed after the world revision ofDryinidae (Olmi, 1984; Mita et al., 2017).
Recently, “types” of Dryinidae were found from old slid samples in the collection of Entomological Laboratory, Faculty ofAgriculture, Kyushu University, Japan. After examination of specimens and label data, we confirmed that they should be part of thetype series of Dryinidae described by Esaki & Hashimoto which have not been recognized by subsequent studies. In this paper, we
compare information of the types based on the original description with existing type series to confirm name-bearing types. Also, weredescribe Apterodryinus tambiniae Esaki & Hashimoto, 1935 (= Gonatopus tambiniae), Pachygonatopus andoi Esaki & Hashimoto,1935 and Pseudogonatopus flavifemur Esaki & Hashimoto, 1932 (= Gonatopus flavifemur) based on rediscovered name-baring types.

Materials and Methods
Specimens are all deposited in the Entomological Laboratory, Faculty of Agriculture, Kyushu University, Japan. Morphologicalterms follow those of Olmi & Xu (2015). In the descriptions POL is the distance between the inner edges of the lateral ocelli; OL isthe distance between the inner edges of a lateral ocellus and the median ocellus; OOL is the distance from the outer edge of a lateral― 75 ―

ocellus to the compound eye. The colors of slide-mounted specimens are relative; it may look different from the color of dry
specimens.
In the specimens examined part, the type series section is the information of all type materials mentioned in the original description; the slide-mounted type section and the pinned type section are the materials examined in this study. The transcription of label
data is surrounded by “ ”. Slash indicates a line break. Translation of the original writing (in Japanese) and authors’ comments areadded in “[ ]”. The information of the type series is retrieved from the original description. Specimens may have a label written as“holotype” or “paratype” even the type was not fixed in the original publication. In such a case, those types are considered as syntypes(ICZN Art. 73.1.3). In some nominal species, the presence of the holotype was implied (written in Japanese like as “タイプを含む材料” [materials including the type]) but no label information of the type was provided in the original publication. Only when the
single specimen from type series is clearly marked or bearing the “holotype” or the “type” label provided by the authors, is it regarded
the holotype fixed in the original publication. When two specimens are marked or bearing a “type” label, they are regarded as all
syntypes.

Other material related to type materials. 1 empty cocoon, “cocoon of Apterodryinus tambiniae Esaki et Hashimoto”.
Note. Now this species is known as Gonatopus tambiniae (Esaki & Hashimoto) (Mita et al., 2017). Gonatopus hagoromo
Terayama & Ohbayashi, 2003 is a junior synonym (Mita et al., 2017). Types have been considered to be lost (Olmi, 1984; Mita &Olmi, 2013), however, the slide-mounted type is found. For more detail, see Xu et al. (2013); Mita et al. (2017).

Notes. Now Gonatopus tenuipes Esaki & Hashimoto is known as a junior synonym of Gonatopus schenklingi Strand, 1913
(Olmi, 1984). Because no male is included in the type series and only one female bearing the holotype label (Fig. 6), the female isapparently the holotype fixed by original designation. The holotype was examined and confirmed by Olmi (1984). For more detail,see Xu et al. (2013) and Olmi & Xu (2015).

Notes. Now Echthrodelphax bicolor Esaki & Hashimoto is known as a junior synonym of E. fairchildii Perkins, 1903 (Olmi,
1984). Because Esaki & Hashimoto (1931) did not designate the holotype, the type status should be syntype even there are the holotype (Fig. 9) and allotype (Fig. 11) labels. The “Holotype” female and the “Allotype” male were examined by Olmi (1984). The
female bearing the “Holotype” label is designated as the lectotype herein. For other information, see Xu et al. (2013) and Olmi & Xu

Notes. Pachygonatopus andoi has been listed as a species incertae sedis (Olmi, 1984; Olmi & Xu, 2015).

Based on the morphology of the lectotype of P. andoi, Tetrodontochelys lucens Olmi,
1984 (= Gonatopus lucens (Olmi)) is considered as a junior synonym of P. andoi (new synonymy). This species is included in themember of Gonatopus group 6 (Xu et al., 2013) (= Gonatopus andoi (Esaki & Hashimoto), new combination). For more detail on
Gonatopus lucens, see Xu et al. (2013) and Olmi & Xu (2015).
