Nematopodius (Nematopodius) flavoguttatus Uchida is recorded from Korea for the first time and this is the firstrepresentative of the genus from Korea. This species was described based on two females from Japan. Therefore,we provide a redescription of the species based on newmaterials fromKorea, and report our observation on colorvariation of males from Korea and Japan.© 2013 Korean Society of Applied Entomology, Taiwan Entomological Society and Malaysian Plant Protection

Introduction

Osprynchotina (Cryptini) are a moderately large subtribe with 88species under nine genera (Yu et al., 2005). It is easily distinguishedfromother subtribes by the longmandiblewith a very short or indistinctlower tooth. The subtribe is found in all major faunal regions except theAntarctic, but most of the species are distributed in the tropics (Townes,1970). In the eastern Palaearctic region, six species of AcroricnusRatzeburg, two of Nematopodius Gravenhorst, three of PicardiellaLichtenstein and one of Stenarella Szépligeti are known (Yu et al.,2005), whereas only three species of Acroricnus have been recordedfrom Korea (Uchida, 1930a, 1930b).

Nematopodius is the largest genus within the subtribe, and containstwo species from the Australasian, 19 from the Oriental, two from theeastern Palaearctic and three from the western Palaearctic regions (Yuet al., 2005). It is divided into three subgenera: Nematopodius, DiapetusCameron and Microchorus Szépligeti (Townes, 1957). The former cancertainly be distinguished from the two other subgenera by thepresence of the upper portion of the occipital carina.

Two eastern Palaearctic species belonging to the subgenusNematopodius, N. flavoguttatus Uchida and N. oblongus Momoi,have previously been known only from Japan (Uchida, 1930a,1936; Momoi, 1967). Here, we report N. flavoguttatus as a species

82 53 811 2376.

new to the Korean fauna. The species was described only from thefemale type and one female collected in Hokkaido, Japan (Uchida,1930a; Momoi, 1967). One male has been reported from Honshu,Japan by Konishi and Nambu (1997) without the description. Onthis occasion, we provide a redescription of the species including abrief description of the male for comparison with the Japanesespecimens.

Material and methods

Morphological terminology follows Yu et al. (2005). Photographsof specimens were captured with an Axiocam MRc5 camera througha stereomicroscope (Stemi SV 11 Apo; Carl Zeiss, Oberkochen,Germany), and were produced with AxioVision40AC software (CarlZeiss, Oberkochen, Germany). Acronyms for depositories of specimensare as follows: National Institute for Agro-Environmental Sciences,Japan (NIAES); Systematic Entomology, Hokkaido University, Japan(SEHU); Yeungnam University, Insect Collection, Korea (YUIC).

DiagnosisNematopodius differs from other genera of Osprynchotina by the

small areolet, the incomplete occipital carina and the compressedovipositor tip. In all other genera, the occipital carina is complete or itslower end is not quite reached to the oral carina, and the ovipositortip is depressed or subcylindrical.

DistributionKorea (New record), Japan.

RemarksThe coloration of the Korean females is well adopted with the

descriptions of Japanese specimens by Uchida (1930a) and Momoi(1967). Among the diagnostic characters used in a key for distinguishingoblongus from flavoguttatus by Momoi (1967), the character ofyellowish white orbital mark cannot be applied for males. The malefrom Korea has the continuous yellowish white marks on the orbit(Fig. 2B) and the lateral margin of the tergite 1, whereas the malefrom Japan has the interrupted yellowish white marks (Fig. 2C,D). Inmales, the color of mesosternum can be used for distinguishing thesetwo species, i.e. the mesosternum is black in flavoguttatus (Fig. 2D)and yellowish white in oblongus. Though oblongus is more abundantthan flavoguttatus in Japan (Momoi, 1967), only flavoguttatus has beenfound in Korea.
