Abstract

Seven species of Neotrichoporoides Girault from China are reviewed, including two new species: N. basiflavus sp. nov., N. flavothorax sp. nov. and two new country record species: N. cavigena Graham, 1991, N. szelenyii (Erdös, 1951). New distributional data for N. mediterraneus Graham, 1986, N. nyemitawus (Rohwer, 1921) and N. viridimaculatus (Fullaway, 1955) are provided and a key to Chinese species is given based on females.

Introduction

The genus Neotrichoporoides (Eulophidae: Tetrastichinae) was erected by Girault (1913) with N. uniguttatus Girault as type species. Currently the genus contains 73 valid species (Noyes 2019). It is distributed widely and especially diverse in Asia, Africa and Australia (Graham 1987), but only four species were known from China: N. mediterraneus Graham, 1986, N. dubius (Girault, 1913), N. nyemitawus (Rohwer, 1921), and N. viridimaculatus (Fullaway, 1955) (Zhu and Huang 2001, 2002; Zhang et al. 2007). Most species of the genus are parasitoids of Diptera in stems of grasses (Graham 1987; LaSalle 1994).

Neotrichoporoides can be recognized by the following combination of characteristics (Graham 1987): malar sulcus usually foveate below eyes; antenna of female with four discoid anelli (only three discoid anelli were found in N. basiflavus sp. nov.), funicular segments usually elongate; mesosoma with pronotum conical, propodeum usually much longer than dorsellum and strongly reticulate, spiracles small; fore wing with MV 5.5–9.5 × as long as STV, the latter very short; external surface of metacoxae sometimes strongly reticulate; body usually with distinct metallic reflections on dark parts or mainly yellow without metallic reflections.

In the present paper, we add four more species, including two new species and two new country record species to the Chinese fauna. A key to Chinese species is given based on females.

Materials and methods

Specimens were collected by sweeping, yellow pan trapping and malaise trapping, and were dissected and mounted dorsally in Canada balsam following the method described by Noyes (1982) or glued to triangular cards. Photographs were taken with a digital CCD camera attached to an Olympus BX51 compound microscope and a Aosvi HK-830 microscope. Most measurements were made from slide-mounted specimens using an eye-piece reticle with an Olympus CX21 microscope. In the descriptions below, measurements/ratio in brackets after measurement/ratio ranges refer to the measurement/ratio of the holotype. Terminology follows the Hymenoptera Anatomy Consortium (2020), and the following abbreviations are used:

F1–4 (flagellomeres 1–4),

MV (marginal vein),

OOL (minimum distance between lateral ocellus and eye margin),

OD (largest diameter of a lateral ocellus),

POL (minimum distance between lateral ocelli),

STV (stigmal vein),

SMV (submarginal vein).

All the specimens listed below were deposited in the insect collections at Northeast Forestry University (NEFU), Harbin, China.
