Abstract

Nine species of Acropimpla Townes, 1960 are recorded from Thailand with three species described as new: A. leoni sp.n., A. natae sp.n., A. patellalutea sp.n. Six species, A. aspera Gupta & Tikar, 1976, A. hapaliae (Rao, 1953), A. leucostoma (Cameron, 1907), A. nakula Gupta & Tikar, 1976, A. taishunensis Liu, He & Chen, 2010, and A. uchidai (Cushman, 1933) are recorded from Thailand for the first time. A key to the females of Acropimpla species in South East Asia is also pro- vided.

Key words: Ephialtini, taxonomy, new records

Introduction

Acropimpla Townes, 1960 is a moderately large genus of the subfamily Pimplinae, with 41 known species, 34 of which occur in the Oriental region (Yu et al. 2012). Recent investigations in this region have revealed a high percentage of undescribed species, indicating that the Oriental fauna is still relatively poorly known (Liu et al. 2010; Pham et al. 2011). Based on recent collections of Ichneumonidae from Thailand, we provide the first record of Acropimpla species for this country, with descriptions of three new species and records of six further species.

Material and methods

This work is based on material collected by the TIGER project, a collaborative effort between staff at the Queen Sirikit Botanic Garden (QSBG), the Thai Forestry Group, the Hymenoptera Institute of the University of Kentucky, and the Natural History Museum of Los Angeles County. Morphological terminology follows that of Gauld (1991). Images were taken at the Alexandru Ioan Cuza University of Iasi (UAIC) (Romania) using a Leica stereomicroscope 205A with DFC 500 camera, combined with Zerene® software and with a Canon Digital Camera 5D, combined with Zerene® software at the Swedish Museum of Natural History (NHRS).

Pongpitak Pranee & Sathit, T2080, QSBG. Diagnosis. This species is characterized by the black with yellow marks on head and mesosoma (Fig. 2a), the yellow face with a black triangular central spot (Fig. 2b), the punctate epicnemium, the propodeum which is weakly convex, coarsely and densely punctate, with dorsal longitudinal carinae on its anterior 0.45 (Fig. 2d), the closely punctate and almost entirely red metasoma, and the ovipositor which is around 2.1 × the length of the hind tibia, with a distinct constriction near its tip (Fig. 2c).

Ovipositor straight, about 1.95 × the length of the hind tibia, weakly compressed laterally and with a distinct constriction near the tip and its lower valves with oblique ridges (Fig. 9e). Colour. Antenna blackish, except scape and pedicel yellow. Face yellow except long blackish triangular area connecting with clypeus, and blackish eye orbits. Clypeus blackish basally, widely brownish centrally. The following body parts yellow: clypeus apically, mandible (except teeth), upper and lower margin of pronotum, subtegular ridge, tegula, scutellum laterally and apically, and metascutellum. The pronotum, mesopleuron, scutellum centrally, propodeum, and mesoscutum are all red. Fore and mid legs yellow, hind coxa and femur red, trochanter and trochantellus pale yellow, tibia reddish apically and pale yellow basally, tarsomeres reddish yellow. Wing membranes hyaline, pterostigma and veins brownish. Metasoma reddish yellow with tergites 1–5 narrowly banded apically with black. Ovipositor reddish with its sheaths black.
