A new species of Macrophya Dahlbom (Hymenoptera: Tenthredinidae) with a key to species of the Macrophya coxalis group from China

Abstract

A new species, Macrophyra pseudocoxalis Li, Liu & Wei, sp. nov., of the genus Macrophya Dahlbom (Hymenptera: Tenthredinidae) from China is described. A key to known Chinese species of the Macrophya coxalis group is provided. The type specimens of the new species are deposited in the Lishui Academy of Forestry, Lishui, Zhejiang, China.

Key to the Macrophya sibirica group (Hymenoptera: Tenthredinidae) with description of a new species from China

“…Macrophya Dahlbom, 1835 Type species: Macrophya montana (Scopoli, 1763) 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 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 (2016Li et al ( , 2018. 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.…”
