43 Introduction
44 The Microgastrinae Foerster, 1863 is a large and diverse subfamily with more than 2700
45 described species worldwide (Yu et al. 2016). This subfamily is one of the most important
46 groups of parasitoids in terms of both species richness and economic importance (Rodriguez
47 et al. 2012). Iconella Mason is a small genus of Microgastrinae that includes solitary
48 endoparasitoids of microlepidopteran larvae (e.g., Pyralidae Latreille, 1809, Tortricidae
49 Latreille, 1802, and Crambidae Latreille, 1810) (Segarra Carmona & Barbosa 1988, Yu et al. Use the following type of citation: North-western Journal of Zoology 2021: e211202
50 2016).
51 Mason (1981) reclassified the subfamily Microgastrinae and described Iconella using the
52 sinuated vein cu-a of the hind wing as main character, that he interpreted as plesiomorphic
53 character among Microgastrinae. Fernández-Triana et al. (2013) considered the presence of a
54 medio-longitudinal carina on the propodeum as an important support for the generic status of
55 Iconella. They noted that this character represented in all New Word species of Iconella have
56 so far been described, however, in some Palaearctic species of Iconella this carina is
57 inconspicuous or absent. Fernández-Triana et al. (2020) were moved some species without
58 medio-longitudinal carina on the propodeum from Iconella and noted further examination of
59 the type series with medio-longitudinal carina on the propodeum will be needed to clarify the
60 taxonomic position of the species.
61 So, the generic status of Iconella remains controversial. For example, van Achterberg (2002)
62 moved the species of the genus Iconella to Apanteles Foerster, because of lack of a reliable
63 suite of character-states. However, Whitfield et al. (2002), Chen & Song (2004) and
64 Fernández-Triana et al. (2013, 2020) didn’t accept that decision. For this paper we use the
65 following character-states to separate Iconellaaccepted from Apanteles paper: in Iconella the hind wing with
66 a sinuous vein cu-a (nervellus) as a plesiomorphic character (not sinuate in Apanteles); the
67 propodeum with a strongNorth-Western medio-longitudinal Journal carina (coarsely of Zoology sculptured to smooth without a
68 medio-longitudinal carina but instead with a more or less well-defined areola and costulae in
69 Apanteles); the lateral grooves of mesoscutellar disc is always parallel-sided (variable in
70 Apanteles); the scutellar lunules (posterior band of mesoscutellum) is always large and
71 triangular (variable in Apanteles).
72 Mason (1981) and Fernández-Triana et al. (2013) included two of Nixon’s species-groups
73 (sundanus-group and part of merula-group) in the genus Iconella. The sundanus-group is
74 recently placed within the genus Neoclarkinella Rema & Narendran, 1996 (Fernández-Triana Use the following type of citation: North-western Journal of Zoology 2021: e211202
75 et al., 2020). The laspeyresiella species group can be distinguished by absence medio-
76 longitudinal carina on the propodeum and hind wing vein cu-a is not sinuate. The
77 laspeyresiella group is erected by Papp (1982) as a new species group of the genus Apanteles,
78 although so far, taxonomic status of this group has been controversial. Kotenko (2007) and
79 Zargar et al. (2019) considered laspeyresiella group in the genus Iconella. However, that
80 decision has not been universally accepted (Lie et al. 2015; Fernández-Triana et al. 2013,
81 2020).
82 In more recent study, Fernández-Triana et al. (2020) reexamined the subfamily
83 Microgastrinae and placed the type species of laspeyresiella-group (e.g., A. laspeyresiella
84 Papp, 1972) within Dolichogenidea Viereck. Also they placed some species of laspeyresiella-
85 group (e.g., Iconella nagyi and I. subcamilla) in the genus Iconella, but they have noted that
86 these species do not have medio-longitudinal carina on the propodeum, one of the main
87 defining characters of the genus. In addition, some species of laspeyresialla-group were
88 placed within Apanteles (e.g., A. nephus Papp, 1974 and A. robustus Hedqvist, 1965)
89 (Fernández-Triana et al., 2020).
90 In this study, we include only some accepted species of merula paper-groups in Iconella. Also, based on
91 Fernández-Triana et al. (2020), we placed I. nagyi (Papp, 1975) and I. subcamilla (Tobias,
92 1976) within IconellaNorth-Western, however, as Fernández-Triana Journal et ofal. (2020)Zoology noted, further examination
93 of the type series will be needed to clarify the taxonomic position of these species.
94 The Palaearctic species of the genus Iconella have been revised and keyed by Nixon (1965
95 1976), Papp (1982), Tobias (1986) and Kotenko (2007). In Iran, the fauna of some
96 subfamilies of Braconidae such as Aphidiinae, Braconinae, Cheloninae, Doryctinae,
97 Homolobinae, Miracinae, and Rogadinae is already catalogued (Rakhshani et al. 2007,
98 Farahani et al. 2012, 2014a,b,c, 2015, 2016, Ameri et al. 2014, 2015, Ghahari & Beyarslan
99 2017), but the Microgastrinae has been poorly studied (Farahani et al. 2014d, Gadallah et al. Use the following type of citation: North-western Journal of Zoology 2021: e211202
100 2015, Ghafoori-Moghaddam et al. 2018, Abdoli et al. 2019a, 2019b, 2019c).
101 More recently, Zargar et al. (2019) revised the Iranian species of the genus Iconella and
102 described two new species from southwestern Iran. Prior to the present study, seven species of
103 the genus Iconella were recorded from Iran (i.e., I. isus (Nixon, 1965), I. myeloenta
104 (Wilkinson, 1937), I. meruloides (Nixon, 1965), I. mongashtensis Zargar & Gupta, 2019, I.
105 nagyi (Papp, 1975), I. simila Zargar & Gupta, 2019 and I. subcamilla (Tobias, 1976))
106 (Ghahari et al. 2011, Kishani-Farahani et al. 2012, Khajeh et al. 2014, Nobakht et al. 2015,
107 Zargar et al. 2019). However, Zargar et al. (2019) listed eight species of Iconella from Iran,
108 but as mentioned before, the species I. laspeyresiella has recently moved to the genus
109 Dolichogenidea (Fernández-Triana et al. 2020). Therefore, as a result of this study and the last
110 checklist of the subfamily Microgasterinae (Fernández-Triana et al. 2020), so far nine species
111 is registered from Iran.
112 The objective of this study is to improve the knowledge of the genus Iconella from Iran. Here,
113 a new species, Iconella brachyradiata sp. nov., is described as a part of the ongoing project
114 “Systematics and biodiversity of the Iranian parasitic Hymenoptera (Ichneumonoidea &
115 Chalcidoidea)”. In addition, we redescribedaccepted two species, paper I. lacteoides and I. meruloides, in

119 Material and Methods
120 The material examined for this study comprises specimens collected under the ongoing
121 project “Systematic and biodiversity of the Iranian parasitic Hymenoptera (Ichneumonoidea
122 & Chalcidoidea)”, supported by Tarbiat Modares University (TMU). Specimens were
123 collected using Malaise traps during March to November from 2010 and 2011 in five
124 provinces in the northern Iran: Alborz, Guilan, Mazandaran, Qazvin and Tehran provinces Use the following type of citation: North-western Journal of Zoology 2021: e211202
125 (Fig. 1). The Malaise traps were placed in different habitats such as forests, rangelands and
126 orchards. The specimens were identified using the keys of Nixon (1965, 1976), Papp (1982),
127 Tobias (1986) and Zargar et al. (2019). Also, relevant type and non-type material which
128 deposited in the Insect Collection of the Department of Entomology, Tarbiat Modares
129 University, Tehran, Iran (e.g., I. meruloides Nixon, 1965; I. mongashtensis Zargar & Gupta,
130 2019; I. myeloenta (Wilkinson, 1937); I. simila Zargar & Gupta, 2019; I. subcamilla (Tobias,
131 1976)), Department of Plant Protection, University of Zabol, Zabol, Iran (e.g. I. isus (Nixon,
132 1965); Iconella nagyi (Papp, 1975)) were studied, and one species (e.g., Iconella lacteoides
133 (Nixon, 1965)) is only checked by the original description and subsequent references.
134 Specimens were photographed with a Keyence VHX-1000 Digital microscope, using a lens
135 with a range of 13–130×. Multiple images through the focal plane were taken of a structure
136 and these were combined to produce a single in-focus image. Measurements were done using
137 an Olympus™ SZX9 stereomicroscope equipped with a graticule. Morphological terminology
138 follows Wharton et al. (1997) for wing venation (see also Fig. 3) and Karlsson & Ronquist
139 (2012) for the other various body parts used in the description of the new species. The body
140 length was measured from anterior marginaccepted of head to paperend of the metasoma (not hypopygium).

426 Discussion
427 In the present study, Iconella is treated as a valid genus. It should be noted that there is a
428 homonymy between Iconella Mason, 1981 and Iconella Jurilj, 1949, diatoms of family
429 Surirellaceae (Jahn et al., 2017). According to the International Commission on Zoological
430 Nomenclature, ICZN (i.e., Article 52.7) “the name of an animal taxon identical with the name
431 of a taxon which has never been treated as animal is not a homonym for the purposes of
432 zoological nomenclature”. Iconella Jurilj, 1949 belongs to kingdom Chromista (Jahn et al.,
433 2017), while Iconella Mason, 1989 belongs to kingdom Animalia, so that, both genera names
434 are valid.
435 Iconella is one of the most complex genera of Microgastrinae, so many of its current species
436 seems to need re-examination of the type materials. Vein cu-a in all the Iranian specimens
437 collected is weakly sinuate and it seemsaccepted that this character paper is specific for the New World
438 species (Fernández-Triana et al. 2013). On the other hand, it is worth emphasizing here that
439 the absence of medio-longitudianlNorth-Western carina inJournal Palaearctic of species Zoology need more investigation on
440 type series.
441 In the present study five provinces (Alborz, Guilan, Mazandaran, Qazvin and Tehran) in the
442 North of Iran have been sampled. Although all specimens of Iconella were collected only
443 from two provinces (Alborz and Qazvin) (Fig. 1). The north provinces of Iran belong to the
444 Irano-Anatolian hotspot (Paknia & Rajaei 2015, Kiani et al. 2017) that is expected to have the
445 highest biodiversity in the country. The new species here described, I. brachyradiata, and the
446 new geographical record of I. lacteoides raised the number of Iconella species in Iran to nine. Use the following type of citation: North-western Journal of Zoology 2021: e211202
447 The number of Iconella species in adjacent countries varies from one to three (Yu et al. 2016).
