E-mail: heikki.hippa@nrm.se Abstract The phylogeny of 50 genera or subgenera of the Sciaridae was studied by parsimony analysis. A cladistic analysis using 138 morphological characters from the adults of fifty-one ingroup and one outgroup species produced one most parsimonious cladogram. Schwenckfeldina, Chaetosciara, and Scythropochroa appeared successively as the sister groups of all other genera included in the analysis. The solution obtained was, in part, different from earlier, traditional views of sciarid phylogeny. The new Oriental genus Xenosciara had the phylogenetic relationship [Metangela + (Pnyxiopalpus + Xenosciara)]. Xenosciara invisa gen. n., sp. n., is described and illustrated. The new monotypic genus is exceptional in its hypopygial structures. Key words: phylogeny, morphology, Sciaridae, Xenosciara, new genus, new species Introduction Sciaridae are small and usually dark-coloured nematocerous Diptera, rich in species, that occur in the world s forested areas. They prefer shaded and humid conditions. They are nonbiting as adults and mostly soil-living or subcortical as larvae. Being rather uniform in structure and, with a few exceptions, lacking striking morphological modifications, their taxonomy has proved difficult at both the species and the supraspecific levels, and their taxonomy as well as their general biology has remained the least studied of all the large nematoceran families. More than 1800 valid species in some 90 genera are currently known. Judging by the abundance of morphospecies, only a small percentage of the actual species and genera have been described so far. In taxonomic revisions that have treated certain tropical genera, about 90% of the species recognized have been new to science Accepted by P. Adler: 12 Oct. 2004; published: 25 Oct. 2004 1

(Hippa and Vilkamaa, 1991, Vilkamaa and Hippa 1996, Hippa et al. 1998, Vilkamaa and Hippa 1999). The supraspecific taxonomy of the Sciaridae is even less studied. Rübsaamen s (1894) and Frey s (1942) studies are the only attempts to study the world fauna at the generic level. For the Palaearctic fauna, Tuomikoski (1960) was the first to try to find natural groups within the family, and his outstanding work is the basis for all subsequent work on the systematics of the Sciaridae. Tuomikoski s (1960) views on genera have generally been followed by most subsequent authors, including Mohrig and Menzel and their coworkers (Menzel and Mohrig 1997, 2000 and references therein), Freeman (1983), and Steffan (1966, 1981). The present authors have used cladistic analysis to test the monophyly of some of the currently recognized genera, and have sometimes obtained strikingly different results when compared with the traditional views (Vilkamaa 2000, Hippa et al. 2003, Vilkamaa et al. 2004, Hippa and Vilkamaa 2004, Vilkamaa and Hippa in press). In a large-scale consideration of the phylogenetic relationships among the genera, Menzel and Mohrig (2000) put forward a phylogeny of all the Palaearctic genera and subgenera. They gave a cladogram and a data matrix, but did not perform any numerical computer analysis on these data. Consequently, their phylogeny was not based on parsimony, and possible character conflicts were not considered from a cladistic point of view (e.g. Schuh 2000). Our aim here was to find a phylogenetically correct placement for the new and exceptional genus discussed here, and to describe it as an example of a previously unknown structural type of Sciaridae. At the same time, we wanted to study the phylogenetic relationhips among the genera of the Sciaridae by parsimony analysis, to obtain a preliminary, parsimony-based hypothesis. Although not complete, our aim was to include in the analysis as wide a variety of the morphological diversity of the world fauna as possible. Materials and methods The new taxon The specimen was collected with a sweep-net and was placed in ethanol. Other body parts except for the abdomen were removed from ethanol and mounted on a microscope slide in Euparal after dehydration in absolute ethanol. The abdomen was briefly treated with potassium hydroxide (KOH), studied under a stereomicroscope in ethanol and under a compound microscope in glycerol. The illustrations were made with the help of a drawing tube attached to a Leitz Diaplan compound microscope, while the abdominal structures were in glycerol. The methods of the phylogenetic analysis are explained below. Phylogenetic analysis The terminals We studied the phylogenetic relationships by parsimony analysis; 138 characters from 2 2004 Magnolia Press VILKAMAA & HIPPA

the adult morphology were coded for 52 terminal taxa (Appendices 1 3). Selected species, the type-species of genera or subgenera when possible, were used as terminals instead of composite taxa or predetermined ground-plan character states. Of the ca. 90 described genera of the traditional Sciaridae, the ingroup consisted of 47 genera or subgenera, including the new genus Xenosciara. Representatives from the other groups of of Sciaroidea were Rangomarama edwardsi Jaschhof & Didham, Sciarosoma borealis Chandler, and the undescribed Sciarotricha biloba Hippa & Vilkamaa (Hippa and Vilkamaa, in press). Rhynchoheterotricha Freeman (an undescribed species) was selected as the outgroup to which the resulting cladograms were rooted. In our cladistic analysis of the Sciaroidea (Hippa and Vilkamaa, in press), Rhynchoheterotricha proved definitively to belong outside the Sciaridae. Many species included in the analysis were known only from the male, but a few were known only from the female. We do not regard this as a problem in this particular data set because most external characters in the Sciaridae are identical in males and females. All terminals were studied from slide-mounted specimens, with the exception of some glycerol-mounts. The material studied is deposited in the following collections (see Appendix 2): Bishop Museum, Honolulu (BPBH), Entomological Museum, Utah State University, Logan (EMUS), Forschungsinstitut Senckenberg, Frankfurt-am-Main (SMFD), Museu de Zoologia da Universidade de São Paulo, São Paolo (MZSP), National Museum of Namibia, Windhoek, (NMNW), New Zealand Arthropod Collection, Auckland (NZAC), Kai Heller Private Collection, Kiel (PKHK), Swedish Museum of Natural History, Stockholm (NRM), The Natural History Museum, London (BMNH), Zoological Museum, Finnish Museum of Natural History, Helsinki (MZH), Zoological Museum, University of Copenhagen (ZMUC). The characters In the analysis, we used the characters with equal weights, and the states of the multistate characters as unordered. We coded the character state as inapplicable (-) when the character in question was absent from a terminal, and as? if the character state was not known. The search programme used does not differentiate between these cases. The data matrix (Appendix 3) was constructed and manipulated with the programme WinClada, Version 100.08 (Nixon 2002). The procedure We searched for the shortest cladograms with the computer programmes NONA, version 2.0 (Goloboff 1999), and Ratchet, together with WinClada. The search parameters used with NONA were hold100000, hold/1000, mult*1000, max* and sswap*;. With these commands and settings, the programme makes a heuristic search and swaps branches with tree bisection-reconnection. The unsupported nodes were collapsed to accept only unambiguous support for the nodes in the strictest sense. The Ratchet search was done using 1000 iterations, with 100 trees to hold per iteration, 25 characters to sample. The resulting cladograms (Figs. 1 5) were studied with Winclada.

Phylogeny of the Sciaridae and the placement of Xenosciara The parsimony analysis with NONA and with Ratchet produced one identical shortest cladogram (881 steps, CI 0.19, RI 0.45; Fig. 1). The result supports the monophyly of the traditional Sciaridae, although with this data set the undescribed Sciarotricha appeared as the sister-group of the Sciaridae, whereas in the analysis of the whole Sciaroidea (Hippa and Vilkamaa in press) that sister-group was the Rangomarama. Schwenckfeldina Frey, Chaetosciara Frey, and Scythropochroa Enderlein appeared successively at the base of the traditional Sciaridae (Figs. 1 and 2). The rest of the analyzed genera were in three main clades (Figs. 1 and 3 5). The peculiar new Xenosciara was placed in the Lycoriella-clade, with the relationship [Metangela + (Pnyxiopalpus + Xenosciara)]. The rather unexpected sister-group relationhip between Pnyxiopalpus Vilkamaa & Hippa and Xenosciara was supported by five character state changes in the cladogram: first flagellomere longer than second (Character 3: 1), dense setosity on flagellomeres (12: 1), dark notal setae (43: 0), very small aedeagal teeth (113: 2), and high number of setae on male sternite 10 (115: 1) (Fig. 5). All these character state changes are homoplaseous throughout the data set and have little to do with the general appearance of the species in question. With regards to cladogram as a whole, the phylogenetic result now obtained is, in part, rather similar but, in part, totally different from earlier hypotheses. When compared with Menzel and Mohrig s (2000) cladogram, which includes 48 of the Palaearctic genera or subgenera, perhaps the most striking differences are that in our solution there is no monophyletic basal Sciara-Trichosia-clade, nor a monophyletic clade including all genera with a front tibial comb, and that Corynoptera s.s. is in the same clade with Epidapus and Bradysia. Some problematic genera such as Xylosciara also have a completely different placement. Menzel and Mohrig s (2000) phylogeny was based on parsimony but it neglected the character conflicts, and, in spite of the phylogenetic terminology used, the coding of characters and the procedure used for obtaining the result cannot be regarded as phylogenetic in the modern sense. In evaluating the results presented here, the following points need to be taken into consideration: 1) The Sciaridae is one of the most difficult dipteran families to analyse because of the a high level of homoplasy in the character states. Molecular data and more precise morphological data (SEM, for example) would have to be included in the analysis to obtain a more stable solution. The instability of recent cladistic solutions is reflected in the position of certain problematic genera (e.g. Xylosciara, Pseudolycoriella) that seem to have a different position, depending on which taxa are included in the analysis (e.g. Hippa et al. 2003, Vilkamaa and Hippa (in press) and Hippa and Vilkamaa (2004)). Furthermore, it is precisely the main clades in our cladogram that have the least support from the characters (Figs. 2 5), and their mutual positions would probably be the first to be falsified with better data. 2) Our present analysis includes about 60% of the described sciarid genera of the world, biased towards the Holarctic groups. Most of the excluded genera were described from the female sex alone and are available only as poorly preserved specimens, ZOOTAXA PHYLOGENY OF SCIARIDAE 2004 Magnolia Press 9

which makes their analysis a challenge. Better material and better understanding of the characters of these poorly known genera is necessary. 3) There are still at least tens, if not hundreds, of undescribed groups, especially in the tropics, which should have generic status according to current thinking. The inventory and description of this vast biodiversity should precede further attempts to obtain hypotheses on sciarid phylogeny. The present work is an illustration of the problems involved in attempting to place a previously unknown morphological type into a preliminary phylogenetic system of the family.

Diagnostic characters Xenosciara differs from all known Sciarinae by each of the following characters: 1) the very long palpomere 1, 2) ventrally fused male gonocoxites, 3) gonostyli movable in a vertical direction, 4) vertical tegmen, 5) setae only on the margin of the cercus, and 6) a setose membrane from the fused ventral part of the gonocoxites covering the aedeagus. In its habitus, Xenosciara is a normal, unspecialized member of the Sciaridae. With its long maxillary palp, Xenosciara resembles Dolichosciara Tuomikoski, Prosciara Frey, 14 2004 Magnolia Press VILKAMAA & HIPPA

and Keilbachia Mohrig, but in these groups palpomere 3 is elongated and distinctly longer than the other palpomeres, and only Xenosciara has palpomere 1 strongly elongated. The basoventrally fused gonocoxites is not a rare character in the Sciaridae and the fused basal part can take up to half the length of the coxites in some groups (Claustropyga Hippa, Vilkamaa & Mohrig), but there are no other taxa in which the ventral aspect of hypopygium resembles that of Xenosciara. A reminiscent structural type is found in several other Sciaroidea, however. The gonostyli that work in a vertical direction are quite exceptional in the Sciaridae, but occur in some taxa of the other Sciaroidea (e.g. Heterotricha Loew, Rhynchoheterotricha Freeman and a few groups of the Cecidomyiidae). The type of association of the gonocoxites and the aedeagus/tegmen complex does not resemble that of any other Sciarinae but is reminiscent of Sciarotricha in terms of the membranous connection between the aedeagus and gonocoxites. Sciarotricha, however, has separate parameres and the membrane is only microtrichose. ZOOTAXA Xenosciara invisa sp. n. Material studied.
