Introduction

Macrophya Dahlbom, 1835 is the third largest genus in Tenthredininae (Hymenoptera: Tenthredinidae). It contains 313 species worldwide, of which 174 extant species have been recorded from China up to April 2020 (Li et al. 2019a, 2019b, Liu et al. 2019a, 2019b, 2019c, 2020a, 2020b).

The taxonomy and distribution of Macrophya in China has been studied by Liu and his co-workers since 1994 and an infrageneric classification of Macrophya into species groups was given by Li et al. (2016, 2018, 2019b). The Macrophya sibirica group, originally proposed by Li et al. (2016), is a large species group within Macrophya, with twenty-two extant species worldwide, fifteen of which are recorded from China. They are all similar in general morphology by having the body length usually 9–12 mm in female and 8–8.5 mm in male, posterior corner of metepimeron without appendage, anal cell of forewing usually with a short, erect cross-vein. Based on these characteristics, they constitute a clearly defined species group within Macrophya. In this study, a new species belonging to this group is described and illustrated from Liaoning, China. According to the available data, species in this group are mainly distributed in northern China. A key to all sixteen Chinese species is provided.

Material and Methods

Eleven specimens of the newly described species were obtained by sweeping in forest fringe zones in Liaoning Province from China (Northeast China) in June 2016. In addition, 1,039 specimens of known species were examined and studied for this work. These specimens were examined with a Motic-SMZ-171 stereomicroscope. Images of the adults were taken with a Nikon D700 digital camera and a Leica Z16APO. The genitalia were examined with a Motic BA410E microscope and photographed with a Motic Moticam Pro 285A. Images were focus-stacked using Helicon Focus (HeliconSoft, Kharkiv, Ukraine) and further processed with Adobe Photoshop CS 11.0.

The terminology of genitalia follows Ross (1945) and that of general morphology follows Viitasaari (2002). For a few terms (e.g., middle fovea and lateral fovea), we follow Takeuchi (1952).

The holotype and all paratypes of the new species are deposited in the Scientific Research and Management Center of East China Pharmaceutical Botanical Garden, Lishui, Zhejiang, China (formerly Lishui Academy of Forestry, LSAF). Most specimens of known species are deposited in the Insect Collection of Central South University of Forestry and Technology, Changsha, Hunan, China (CSCS), and other specimens are deposited in LSAF.

Abbreviations: (OOCL) the distance between a lateral ocellus and the occipital carina, or the hind margin of the head where this carina would be if it was developed (Benson 1954). (OOL) the shortest distance between an eye and a lateral ocellus. (POL) the distance between the mesal margins of the two lateral ocelli.

Taxonomy

Macrophya sibirica species group

Diagnosis

Species of the Macrophya sibirica group can be recognized using the diagnosis provided by Li et al. (2016), and in particular by the following combination of morphological characters: body mainly black, partly white, without metallic tinge; antenna entirely black; apical margin of labrum usually white; clypeus usually largely or entirely black; anterior margin of clypeus incised (usually not deeply), lateral lobe short; posterior corner of metepimeron sub-quadrate, without appendage; abdominal tergum 1 usually with white maculae, but sometimes completely black in a few species; anal cell of forewing usually with a short, erect cross-vein, or in some species with a middle petiole, shorter than vein cu-a; ergot of penis valve distinct.

The M. sibirica group comprises a large portion of the Macrophya species and is morphologically similar to the M. malaisei group by having the anterior margin of clypeus roundly incised, lateral corners short and broad; anal cell of forewing usually with short and erect cross-vein; serrulae of lancet usually protruding. The M. sibirica group differs from the latter group and from others in having additionally: posterior corner of metepimeron sub-quadrate, without appendages; abdominal tergum 1 usually with white maculae. The M. sibirica group is represented in China by fifteen previously described species and one new species described here. The collection site of the new species in northern China at Mt. Jiulongchuan in Liaoning Province, is shown in Fig. 1. They can be separated using the following key.

Distribution

China (Liaoning).

Variation. Six male specimens with clypeus entirely black; one male specimen with hind tibia with a small white macula.

Etymology

The specific name nigrotrochanterata is derived from two Latin words “nigro” and “trochanter”, in reference to the entirely black trochanters in both sexes.

Discussion

The M. sibirica groupis the third largest of the defined species groups of Macrophya. At present, fifteen species belonging to this group were recorded from China by Li et al. (2018), plus the new species described in this work: M. carbonaria, M. convexina, M. crassitarsalina, M. harbina, M. maculipennis, M. maculoepimera, M. nigrotibia, M. nigrotrochanterata sp. nov., M. potanini, M. revertana, M. shii, M. sibirica, M. soror, M. stigmaticalis, M. tripidona, and M. typhanoptera. In Europe, there are six recorded species from this group: M. albicincta (Schrank, 1776), M. alboannulata A. Costa, 1859, M. carinthiaca (Klug, 1817), M. convexiscutellaris Muche, 1969, M. parvula Konow, 1884, and M. ribis (Schrank, 1781). In Japan, there are two recorded species from this group: M. carbonaria and M. timida Smith, 1874. Macrophya sibirica is distributed in Korea and Siberia, M. parvula in Syria, M. potanini in Vladivostok, and M. carbonaria in the Russian Sakhalin island. Among the species of the group, a host plant is known only for M. carbonaria Smith, 1874, which is associated to Sambucus williamsii Hance (Adoxaceae) (Li et al. 2018). Our key to species and distribution map of the M. sibirica group (Fig. 27) should facilitate the recognition and identification of the Chinese species.
