Introduction

The subfamily Ichneumoninae is a very large group of Ichneumonidae (Hymenoptera) with almost 4400 described species worldwide (Yu et al. 2016). Although this group includes many large and colourful species, our knowledge of the taxonomy and biology is still incomplete even in better-known areas, such as Europe.

Up to now, almost 700 species of Ichneumoninae are listed for the Oriental Region in a recent catalogue (Yu et al. 2016), but many species are still undescribed (Broad et al. 2018).

In recent years, I had the opportunity to study Oriental Ichneumoninae from several European museums resulting in the descriptions of many new species (Riedel 2011, 2013, 2017a, 2017b). Here, I report new findings on the Oriental Ichneumoninae from the Senckenberg Deutsches Entomologisches Institut at Müncheberg, Germany (SDEI).

Material and methods

This publication is based on the material of Ichneumoninae collected by a survey by the SDEI in Yunnan and Sichuan in 2009. The collections were made using hand-nets and Malaise traps in mountain areas of these provinces at altitudes between 1700 m and 3000 m. All examined specimens are actually deposited in the SDEI. The holotypes will later be forwarded to ASM (Asian Sawfly Museum, Jiangxi Normal University, Nanchang, Jiangxi, China).

For the descriptions below, morphological terms usually follow Broad et al. (2018). Distributional data were taken from the catalogue of Yu et al. (2016). For the comparison of the new species with known taxa, I usually referred to the published original descriptions and available images of known species and the material in my collection. For measurements, the following relationships were used: length of 1st flagellar segment was measured in lateral view (length without annellus) and length and width of hind femur in lateral view. For the punctation of body parts, the following definitions were used: very sparse – distance between punctures > 2× the diameter of punctures; sparse – distance 1.1–2.0× the diameter; rather dense – distance about as large as puncture diameter; dense – puncture diameter larger than distance between punctures.

For measurements, an Olympus SZX 7 stereomicroscope with dividing eyepiece was used. The figures were mainly taken with an Olympus SC 50 CCD-camera using the cellSens Imaging software and processed with Helicon Pro software and Microsoft Office Picture Manager.

Abbreviations: OED - distance between lateral ocellus and compound eye; OOD - distance between lateral ocelli. HT - holotype, PT - paratype.

Rugichneumon gen. nov.

Type species

Rugichneumon tricolor sp. nov.

Remark

The new genus has an intermediate form of the propodeum: it is more or less gradually sloping posteriorly (as in Protichneumonini sensu Heinrich 1968b), but the area dentipara is not distinctly elongate (as in Ichneumonini sensu Heinrich 1968b). The area basalis is absent and only indicated by a median bulging of the area superomedia towards the postscutellum. The anterior tergites have a very coarse surface structure. The base of the petiolus is slightly wider than high (as in the tribe Platylabini), but the new genus differs from members of Platylabini by several features, such as its unmodified mandible and oxypygous metasoma. The new genus is included in the tribe Ichneumonini sensu Santos et al. (2021) here. In the key to the Oriental genera of Ichneumoninae (Townes et al. 1961), the new genus runs to Celebijoppa Heinrich, but differs by a different carination of the propodeum (distinctly dorsal and postero-dorsal faces which meet in a distinct angle in Celebijoppa) and the very coarse reticulate surface structure of the anterior metasomal tergites.

Remarks

This new species is a member of the genus Stenaoplus Heinrich as re-defined by Heinrich (1968b: 1110–1111) and runs to that genus in the key of Oriental Ichneumoninae (Townes et al. 1961). It is characterised by the modified mandible which is distinctly narrowed behind base and slender medially and distally and resembles the mandibular form found in Benyllus Cameron, by its almost pyramidal scutellum and by a short blunt denticular lamella at the postero-lateral edge of area dentipara. From other known Oriental Stenaoplus species, it can be differentiated by the modified structure of the mandible and the colour pattern of the metasoma with yellowish posterior bands on all tergites.

Male. Unknown.

Remarks

This new species belongs to a group of Oriental genera which were all included under the name Cratichneumon by Townes et al. (1961). Heinrich (1980) separated several genera which had been synonymised under Cratichneumon, such as Lareiga Cameron and Sycaonia Cameron and described several new genera belonging to his subtribe Cratichneumonina. In his key of this group, the new species runs to Sycaonia Cameron, but the form of the scutellum resembles the genus Togeella Heinrich, although the lateral swellings are much weaker than those found in Togeella and the areolet is pentagonal, not rhombic. Here, I provisionally include the new species in the genus Sycaonia Cameron, but the taxonomy of the Oriental genera belonging this group needs extensive revision. In the key of Oriental Sycaonia species (Heinrich 1980: 171–172), the new species runs to S. rufofacies Cameron, but differs by its colour pattern.

Remarks

This new species differs from the other known Oriental ♀♀ of Asthenolabus Heinrich by the entirely ivory 1st to 4th hind tarsomeres. It might represent the unknown ♀ of A. vietnamensis Riedel, 2011, which also has ivory hind tarsi, but differs from A. vietnamensis by the less extensive ivory colouration of the head and mesosoma.

Remarks

This new species resembles the type species of Cratolaboides, C. palpalis Tereshkin, 2009 (see Tereshkin (2009: 1471–1474)). It differs by more slender basal flagellar segments (1st segment 3.7× as long as wide in C. palpalis), ivory colouration of mesosoma and different colour pattern of the hind leg (hind femur and tibia entirely red in C. palpalis).
