Abstract/OtherAbstract:
The Chinese fauna of the Fannia postica-group Chillcott (1961) is reviewed, the diagnostic features of this group are redefined, one new species, Fannia nudifemoratasp. n., is described, and a key to the males of nine known species is given. One new junior synonym, Fannia tigripeda Xue, Wang&Li, syn. n. for Fannia stigi Rognes is established. To facilitate comparisons of the species, Fannia aethiops Malloch, Fannia ardua Nishida, Fannia discoculea Xue, Fannia ringdahlana Collin, Fannia postica (Stein), Fannia spathiophora Malloch, and Fannia stigi Rognes are redescribed and illustrated. The geographic distribution of the known Chinese species is updated.

Introduction

The [taxon-name: Fannia postica]-group was originally established in the genus [taxon-name: Fannia] Robineau-Desvoidy by Chillcott (1961), consisting of two subgroups, the [taxon-name: Fannia postica]-subgroup and the [taxon-name: Fannia spathiophora-]subgroup. Fifteen species were included from the Holarctic Region (Chillcott 1961). Since then, (Nishida (1975, 1976), Rognes (1982), and Xue et al. (2001) have studied the [taxon-name: Fannia postica]-group from Japan, Europe, and China, respectively, forming a sound basis for further research on this group. Rozkošný et al.(1997) listed nine European species of the [taxon-name: Fannia postica]-group and transferred [taxon-name: Fannia ringdahlana] Collin from the [taxon-name: Fannia spathiophora]-subgroup to the [taxon-name: Fannia postica]-subgroup. Gregor and Rozkošný (2005) described an additional new species of the [taxon-name: Fannia postica]-group from Slovakia. So far, twenty-two species of the [taxon-name: Fannia postica]-group are known worldwide, of which eight species belong to the [taxon-name: Fannia postica]-subgroup and the others to the [taxon-name: Fannia spathiophora]-subgroup.

Before the present contribution, eight species of the [taxon-name: Fannia postica-]group were known in China (Nishida 1975, Fan 1992, Xue and Wang 1998, Xue et al. 2001, Wang and Xue 2002, Wu and Wang 2002, Su and Wang 2004, Wang et al. 2006). In recent years we have been engaged in faunal studies of this group of flies in China, and have found one further undescribed species from the Tibetan Plateau.The purpose of this paper is to review the [taxon-name: Fannia postica-]group, describe one new species, and provide a key to the known Chinese species. Based upon the morphological characters, we also discuss the diagnostic characters of this group.


Materials and methods

The morphological terminology follows McAlpine (1981), except that we follow Stuckenberg (1999) in using “postpedicel” for first antennal flagellomere. Absolute measurements are used for body length in millimetres (mm). Abbreviations used for characters include: a = anterior seta, acr = acrostichal seta, ad = anterodorsal seta, av = anteroventral seta, d = dorsal seta, dc = dorsocentral seta, ia = intra-alar seta, p = posterior seta, pd = posterodorsal seta, pra = prealar seta, and pv = posteroventral seta.

Our study of the [taxon-name: Fannia postica]-group was based on an examination of specimens of [taxon-name: Fannia postica], [taxon-name: Fannia ringdahlana], [taxon-name: Fannia aethiops], [taxon-name: Fannia ardua], and [taxon-name: Fannia spathiophora], and the holotypes of [taxon-name: Fannia discoculea], [taxon-name: Fannia nudifemorata] sp. n., and [taxon-name: Fannia stigi]. Data on [taxon-name: Fannia coculea] Nishida was taken from Nishida (1975). All specimens studied in this paper, including the types of new species, are deposited in the Institute of Entomology, Shenyang Normal University, Shenyang.

Remarks.

This new species belongs to the [taxon-name: Fannia spathiophora]-subgroup of [taxon-name: Fannia postica]-group. It can easily be separated from its allies by hind femur without stout pv and bare from p to pv surface in distal 1/3. It resembles [taxon-name: Fannia ardua] but differs from the latter in having the median part of frons about 2.0 times as wide as anterior ocellus, frontal setae 11–13, lower calypter not projecting beyond upper one, haltere dark brown at apex. The new species is also similar to [taxon-name: Fannia umbrosa] (Stein, 1895), but differs from it in having hind femur without distinct pv row in distal 1/3.

Description.

MALE. Body length 4.5–5.0 mm. Eye bare, facets slightly enlarged on anterior margin in upper part; fronto-orbital plate with dark cupreous pruinosity; the median part of frons about 2.5 as wide as anterior ocellus, slightly narrower than postpedicel, frontal vitta black, linear at middle, frontal setae 8 or 9, nearly reaching ocellar triangle; parafacial with silvery-grey pruinosity, slightly narrower than 1/3 of postpedicel width at middle; antenna black, postpedicel about 2.5 times as long as wide, arista distinctly swollen at base, the longest hairs slightly shorter than aristal base; gena and genal dilation with black hairs; genal height about 1/10 of eye height; proboscis short, labella large, the length of prementum 2.5 times as long as its width, palpus black, slightly longer than prementum. Thorax ground-colour black, with thin grey pruinosity, slightly shining, scutum without distinct stripe; presutural acr biserial, only prescutellar pairs slightly stout, the distance between two acr rows slightly narrower than the distance between acr row and dc row, dc 2+3, ia 0+2, pra 2, the anterior one about 1/2 the length of posterior notopleural seta, notopleuron without setulae; basisternum, proepisternum, anepimeron, meron and katepimeron bare; katepisternal setae 1:1; spiracles brownish; calypters brownish, lower one not projecting beyond upper one. Wing brownish; tegula black, basicosta brown, costal spine inconspicuous; vein Sc curved bow-like; node of Rs bare on ventral and dorsal surfaces; vein R4+5 straight, veins R4+5 and M parallel to each other distally; crossveins without obvious cloud; haltere dark brown.

Remarks.

Rognes (1982) described [taxon-name: Fannia stigi] as new to science from Norway and Sweden, and also provided detailed description and high-quality illustrations. When re-examined the holotype of [taxon-name: Fannia tigripeda], we found its morphological characters, especially the male terminalia, is similar with [taxon-name: Fannia stigi]. Whereas, we have not studied the types of [taxon-name: Fannia stigi], but it is clear from Rognes’s notes and figures on stigi that our tigripeda is actually his stigi. An anonymous reviewer also pointed out the possible synonymy of [taxon-name: Fannia stigi] and [taxon-name: Fannia tigripeda]. We confident that [taxon-name: Fannia tigripeda] is a new junior synonym for [taxon-name: Fannia stigi].

Discussion

Chillcott (1961) revised the Nearctic species of the genus and assigned the 148 Holarctic species to 11 species groups and 15 subgroups, including the [taxon-name: Fannia postica]-group. He recognized that the relationship between the [taxon-name: Fannia postica]-group, [taxon-name: Fannia hirticeps]-group and [taxon-name: Fannia lugubrina]-group was very close (Chillcott 1961). Since Chillcott (1961), Domínguez and Roig-Juñent (2008) proposed a phylogenetic hypothesis of the family [taxon-name: Fanniidae], using 151 characters from adult external morphology and female and male terminalia for 78 fanniid species. The analysis, including the [taxon-name: Fannia postica]-subgroup and [taxon-name: Fannia spathiophora-]subgroup, also recovered the paraphyletic of the [taxon-name: Fannia postica]-group, which nested within the [taxon-name: Fannia carbonaria]-group, [taxon-name: Fannia hirticeps]-group and [taxon-name: Fannia lugubrina]-group (Domínguez and Roig-Juñent, 2008). A phylogenetic revision of the genus [taxon-name: Fannia], from molecular data and more characters of immature stages or adult morphology,at the species-group level is required to establish a more reasonable species-group classification.

After a systematic study of these species and related species, we found that the [taxon-name: Fannia postica]-group can be distinguished from other [taxon-name: Fannia] in having the median part of the male cercal plate distinctly swollen in ventral view, the median part curving anteriorly and the apex curving posteriorly in lateral view. In the course of this study, we also found that a number of characters, including the number of distal av on hind femur and the shape of male cercal plate (Chillcott 1961: 101), which have previously been described as being diagnostic characters for the [taxon-name: Fannia postica]-subgroup and [taxon-name: Fannia spathiophora]-subgroup, are variable and unreliable.
