Abstract
For the first time in more than 100 years, a new western Palaearctic species of Heloridae is described. Specimens of Helo-
rus alborzicus Izadizadeh, van Achterberg & Talebi sp. nov. and Helorus ruficornis Frster were collected from the Al-
borz province of Iran. An illustrated identification key for Western Palaearctic Heloridae is provided.
Key words: Helorid wasps, taxonomy, identification key, Iran
Introduction
Members of the proctotrupoid family Heloridae Frster, 1856 develop as larval endoparasitoids in green lacewings
larvae (Neuroptera: Chrysopidae) (van Achterberg 2006), emerging as adults from the host cocoon (Masner 1993).
The single helorid genus, Helorus Latreille, 1802 is represented by 12 species in the Palaearctic, Nearctic,
Neotropical, Indo-Australian and Afrotropical regions (van Achterberg 2006).
Heloridae can be readily characterized by the combination of the following characters: body 68 mm; antennae
with 15 flagellomeres; first flagellomere ring-like and distinctly shorter than subsequent flagellomeres; antennal
sockets situated near mid height of the head in frontal view; length of fore wing 2.55.2 mm; distinct pterostigma
present; five closed wing cells present; subtriangular first medial cell (1m-cu) present; vein RS+M present; vein 1
RS absent; tarsal claws pectinate; first metasomal segment elongate; metasomal tergites 24 fused into a syntergite
(Kusigemati 1987, Masner 1993).
In this paper, we describe a new species, Helorus alborzicus Izadizadeh, van Achterberg & Talebi sp. nov.
from Iran and provide an identification key for West Palaearctic Helorus.
Material and methods
Specimens of the present study were collected using Malaise traps in Mazandaran and Alborz provinces of Iran.
The specimens were extracted from the traps and sorted weekly; the specimens were transferred to 70% ethanol
and stored in the freezer. For the preparation of samples, they were transferred to a mixture of 40% xylene and 60%
pure ethanol, after two days to amyl acetate for one day and finally placed on a piece of absorbing paper for drying
(AXA method, van Achterberg 2009). Photographs were taken using an Olympus TM SZX9 stereomicroscope
equipped with a BMZ-04-DZ digital imaging camera (Behin Pajouhesh Co., Iran). Image stacks were combined
with Combine ZP1.0 (Hadley 2010). Morphological terminology follows Townes (1977) and van Achterberg
