1 Introduction

The subfamily Alysiinae （Hymenoptera，Braconidae） is a large and commonly collected subfamily，which contains over 2，440 described species worldwide （Yu et al.2016）.The alysiine genus Hylcalosia Fischer，1967，currently contains 18 described species.Yao et al.（2019） described five new species （H.bothynis n.sp.，H.dichromata n.sp.，H.eurykephale n.sp.，H.leura n.sp.，and H.perkna n.sp.） from Thailand.Hylcalosia has no known hosts.

2 Material and methods

Specimens were collected，preserved，dehydrated，and mounted as described in Yao et al.（2015a）.Specimens were examined using a Leica MZ 9.5 stereomicroscope with 25× oculars.Images were acquired using a Leica M205C digital camera stereomicroscope system and with the software Leica Application Suite v4.2.All images were further processed using various minor adjustment levels in Adobe Photoshop?，such as image cropping and rotation，adjustment of contrast and brightness levels，and background enhancement.Terminology for morphological features and setation largely follows Sharkey and Wharton （1997），as well as general terminology pertaining to Braconidae.F1，F2 etc.= first （most basal） flagellomere，etc.T1，T2 = first （most basal） tergum of the metasoma，etc.The diagnosis is based primarily on Wharton （1980） and van Achterberg （1986）.
