Abstract

The tribe Planitorini van Achterberg (Hymenoptera: Braconidae: Euphorinae) is revised. One new genus Paramannokeraia gen. n. (type species: P. gibsoni sp. n.) and five new species from Australia are described and illustrated: Mannokeraia albipalpis van Achterberg, sp. n., M. nigrita van Achterberg, sp. n., M. punctata van Achterberg, sp. n., Paramannokeraia gibsoni van Achterberg & Quicke, sp. n. and P. juliae van Achterberg, sp. n. The tribe Mannokeraiini van Achterberg, 1995, is synonymized with the tribe Planitorini (syn. n.).

Introduction

The subfamily Euphorinae Foerster, 1863 (Hymenoptera, Braconidae) is morphologically a very diverse group (Stigenberg et al. 2015), including many genera containing parasitoids of adult insects (Shaw and Huddleston 1991). The entirely Australian tribes Mannokeraiini van Achterberg, 1995, and Planitorini van Achterberg, 1995, are two aberrant groups, each containing only a single genus: Mannokeraia van Achterberg, 1995, with wingless females and Planitorus van Achterberg, 1995, with normally winged females (van Achterberg 1995). Accidently (partly because of their very derived morphology), the senior author referred the genera to the subfamilies Masoninae van Achterberg, 1995, and Betylobraconinae Tobias, 1979, respectively, but according to DNA analysis (Stigenberg et al. 2015) and some details of their morphology (e.g. the petiolate first metasomal tergite with its submedially situated spiracles) they belong to the subfamily Euphorinae. Earlier DNA analysis by Belshaw and Quicke (2002) and Sharanowski et al. (2011) corroborated already the inclusion of this group in the Euphorinae. In this paper the tribes Planitorini and Mannokeraiini are formally synonymised, and a new genus (Paramannokeraia gen. n.) and four new species are described and illustrated.

For the identification of the subfamily Euphorinae, see van Achterberg (1993), for more references see Yu et al. (2016) and for the terminology used in this paper, see van Achterberg (1979, 1988, 1993).

Material and methods

The studied material concerns all the Planitorini and Mannokeraiini specimens used for DNA analysis and some additional specimens collected by Dr L. Masner (Ottawa). So far, the specimens have been provisionally identified up to genus level (Belshaw and Quicke 2002, Sharanowski et al. 2011, and Stigenberg et al. 2015). Observations and descriptions were made with an Olympus SZX11 stereomicroscope and fluorescent lamps. Photographic images were made with the Keyence VHX-5000 digital microscope and processed with Adobe Photoshop CS5, mostly to adjust the size and background.

Measurements are performed as indicated in van Achterberg (1988). The length of the first metasomal tergite is measured medially from apex of adductor muscle to apex of tergite. Additional non-exclusive characters in the key are between square brackets. The following abbreviations are used for the depositories: ANIC = Australian National Insect Collection, Canberra, Australia; CNC = Canadian National Collection of Insects, Ottawa, Canada; HIC = Hymenoptera Institute Collection, University of Kentucky, Lexington, USA; NHRS = Naturhistoriska Riksmuseet, Stockholm, Sweden.

Diagnosis

Antenna of ♀ with 16–20 segments, and segments of apical half moniliform (Figs 11, 19, 38, 87), of ♂ with 28–32 segments and segments much longer than wide (Figs 13, 44, 51), pedicellus of ♀ narrower than scapus (Figs 19, 35, 58, 75; but much less so in Planitorus: Fig. 95); maxillary palp with 6 segments and labial palp with 4 segments; antennal sockets on facial protuberance, sockets remain separated from each other by distance from socket to eye (Figs 23, 35, 57) or touching each other (Fig. 85); mesosoma depressed (Figs 19, 87) or normal (Figs 3, 28, 58); scutellar sulcus wide and more or less curved (Figs 41, 62, 69) or narrow and curved (Figs 90); ♀ wingless (Fig. 18) or macropterous (Figs 2, 56, 84) as males; veins 3-M and 2-1A of fore wing largely unsclerotized (Figs 67, 84); vein m-cu of fore wing postfurcal (Figs 2, 56, 84); vein CU1b of fore wing absent (Figs 2, 29, 56, 84); vein 2-M of fore wing distinctly longer than vein 3-SR (Figs 2, 56, 84); vein M+CU of hind wing 2.0–2.5 times as long as vein 1-M and vein 1-M 1.3–2.0 times as long as vein 1r-m (Figs 2, 29, 56, 84); fore leg of ♀ robust (Figs 7, 21, 37, 63, 76, 89); first metasomal tergite narrow basally, more or less petiolate and its spiracle submedially situated (Figs 22, 32, 49, 59, 93), basal quarter or half of first metasomal tergite tube-shaped, first sternite more or less free from tergite in males of Mannokeraia and in other Planitorini, but ventrally closed in females of Mannokeraia.

Notes

The DNA analysis by Stigenberg et al. (2015) clearly shows that despite the different general morphology of the adults both tribes belong together. The more or less developed facial prominence, the largely unsclerotized vein 3-M of fore wing, the basally narrow first tergite and the apical moniliform antennal segments of females are shared by all three genera.

Figs 56–65, 66, 67–76, 77–83

Distribution

Australia (two species).

Notes

Because of its venation, shape of the telotarsi, submedial position of the spiracle of the first tergite and shape of the first tergite, the genus belongs to the subfamily Euphorinae within which it belongs to the tribe Planitorini. It resembles Mannokeraia, because of the small pedicellus (much narrower than the scapus; Fig. 58), apical antennal segments of the female strongly moniliform and pedunculate, the face moderately convex medio-dorsally, the lack of the medio-posterior depression of the scutellum, the robust fore femur, the setose eyes and the long pronotal collar. According to the DNA analysis by Stigenberg et al. (2015)Paramannokeraia is sister to Planitorus (sharing the presence of dorsope on the first tergite, and the ventrally flattened and narrower clypeus); the two genera forming a sister group to Mannokeraia which has the first tergite lacking dorsope, and the clypeus transverse and with a steep ventral face.
