Abstract

Pseudophoxinus burduricus sp. n. is described from drainages of Salda and Burdur lakes, southwestern Turkey. It is distinguished from other Anatolian Pseudophoxinus by a combination of characters: lateral line incomplete, with 21-39 (commonly 26-37) perforated scales and 47-57+1-2 scales in lateral series; 10½-12½ scale rows between lateral line and dorsal fin origin, 3-4(5) scale rows between lateral line and the pelvic fin origin; dorsal fin commonly with 7½ branched rays; anal fin commonly with 6½ branched rays; 7-8(9) gill rakers on the first branchial arch; a faint and diffuse epidermal black stripe from eye to caudal fin base in alive and preserved individuals; mouth slightly subterminal, tip of mouth cleft on about level of lower margin of eye; snout rounded, its length greater than eye diameter. Comparison is given with all Pseudophoxinus species from western Anatolia.

Introduction

According to Perea et al. (2010), there are 14 distinct clades within Leuciscinae of inner waters across the Mediterranean Region, 9 of which being represented in Anatolia. Among these, phylogenies of the genera and are most debated; indeed even taxonomic status of some species is uncertain. Two well-defined monophyletic clades represent Anatolian species: first of these corresponds to Central Anatolian species complex including , , , , , , , , , and a probable undescribed species; while the other includes Levantine taxa, namely , , and (Perea et al. 2010). Speciation in is heterogenous, as mentioned by Hrbek et al. (2004) and Bogutskaya et al. (2007), and discrepancies between morphological and molecular relationships can be seen (Perea et al. 2010). Separation of the taxa in Anatolia and western Asia into two groups by Bogutskaya et al. (2007), according to a comparison of morphological parameters (sensory pores, scales and their arrangement on the body, vertebral counts, and supraethmoid bone) with that of the type species is another example of the high degree of variability in the genus. Morphological and phylogenetic distinctness of (Hrbek et al. 2004: 305), and its closeness to the - lineage (Perea et al. 2010) brings some doubts about monophyly of the Anatolian taxa. As stated by Hrbek et al. (2002, 2004), Anatolia is an important diversification center for the genus which shows allopatric speciation especially in basins of Bey Dağları, Büyük Menderes, Tuz Lake and Lakes District. However, the complex taxonomy of the genus in these basins is still unresolved. Although including several lakes and springs of Lakes Region (Lake Salda, Karapınar Spring near Yeşilova district, Düğer Spring, Lake Bahçeözü, Sazak Spring and Kırkpınar Springs) in the distribution area of , Bogutskaya (1992) mentioned that populations from Upper Büyük Menderes basin (Lake Işıklı and Düden Spring near Dinar) morphologically differed from remaining populations in having larger scales and shorter lateral line, fewer lateral series scales and gill rakers on the first branchial arch, as well as fewer vertebrae. According to molecular data presented by Hrbek et al. (2004) Kırkpınar (Lake Söğüt source, Korkuteli) and Avlan source (Elmalı) populations were clearly separated from those in the basins of the lakes Salda and Burdur. Freyhof and Özuluğ (2009) identified populations of Kırkpınar as a new species, PageBreak, and populations of Lake Salda and Lake Burdur basin as . Perea et al. (2010) did not examine any material from either the type locality (Onaç Stream-Bucak) or other known localities of (Kestel Swamp-Bucak, Düğer Spring, Lake Karataş and Sazak Spring) and used only mitochondrial and nuclear DNA markers of Lake Salda specimens as representatives of . Thus, it was not possible to explain diversification of in southwestern Anatolia (Fig. 1) in its entirety. Furthermore, since its description by Ladiges (1960), sufficient information on distribution and taxonomy of has not been given up to date. With regard to the above mentioned morphological and molecular data, it became apparent that the taxonomic position of populations in Burdur and Salda lake basins needed clarification and this led to the present study.

Materials and methods

Fish specimens were caught by pulsed DC electrofishing equipment and killed by over anaesthetization, preserved in 5% formalin. Material is deposited in: IFC-ESUF, Inland Fishes Collection, Eğirdir Fisheries Faculty of Süleyman Demirel University. Counts and measurements follow Kottelat and Freyhof (2007), all measurements being point to point made with a digital calliper (0.01 mm sensitive). Standard length (SL) was measured from the tip of the upper lip to the end of the hypural complex. The length of the caudal peduncle was measured from behind the base of the last anal fin ray to the end of the hypural complex, at mid-height of the caudal fin base. Lateral line scales are counted from the anteriormost scale (the first one to touch the shoulder girdle) to the posteriormost one. Scales in lateral series are counted along the midlateral line from the first one to touch the shoulder girdle to the last scale at the end of the hypural complex. Scales on the caudal fin itself are indicated by “+” (Freyhof and Özuluğ 2009). The last two branched dorsal and anal fin rays articulating on a single pterygiophore were counted as 1½. Vertebral counts were obtained from radiographs and counted as total, predorsal, abdominal and caudal vertebrae following Naseka (1996). Abdominal vertebrae were counted from the first Weberian vertebra to the one just anterior the first caudal vertebra. The first caudal vertebra is that with its haemal spine fully developed. The count of total and caudal vertebrae includes the last complex vertebra bearing hypurals. Osteological characters were examined in cleared and stained with alizarin Red-S specimens and from radiographs (Bogutskaya 1996). The morphometric characters of the two species of from Turkey were compared by Principal Component Analysis (PCA) using a covariance matrix on log–transformed measurements and counts with the software package PAST version 1.8 (Hammer et al. 2001).

Distribution.

is known only from the lakes and their sources in Lake Burdur Endorheic Basin: Değirmendere Creek, Lake Karataş, Düğer and Sazak (or Kümbet) springs, Dereköy Stream, Lake Salda and Salda Stream (Fig. 1). Değirmendere Creek is a 5 km long creek flowing into the Karamanlı reservoir, which is connected with artificial reservoir Lake Karataş. Düğer spring is a source of Lake Burdur, while Sazak Spring is a source of Lake Yarışlı. Dereköy Stream is an approximately 5 km long rivulet formerly draining into Çorak (or Akgöl) Lake which, due to a small reservoir constructed in 1970, no more can reach the lake. The new species can be encountered in the shallow parts of the reservoir and the small stream flowing into it. Other species present were: (Ladiges, 1960), Erk’akan, Özeren & Nalbant, 2008 and (Walbaum, 1792) (an escape from fish farms in Karamanlı reservoir)in Değirmendere, in Düğer Spring only and in Salda Stream only (Kosswig & Sözer 1945).

Etymology.

The species is named after the Burdur Province where the type locality is located.

Discussion

Hrbek et al. (2004) stated that monophly of Anatolian taxa was not well supported and these represented 6 distinct clades. Of these, Lakes Region populations (Lakes Salda and Karataş, Düğer Spring, Karapınar) identified as formed Clade IV, while the Avlan and Kırkpınar populations identified as (now ) formed a separate clade (Clade VI). Perea et al. (2010) mentioned of two well defined monophyletic groups within Anatolian taxa, though not discussion interrelationships of these two. A phylogenetic tree based on the cytb gene sequence, Hrbek et al. (2004: 299) showed presence of two different clade; (I) Lake Avlan and Kırkpınar (Lake Söğüt source) populations () and (II) populations from Burdur and Salda basins. In this study, we also morphologically compared the new species with (the Onaç Stream and Kestel Swamp), (dried Lake Söğüt [Kırkpınar Village, Korkuteli] and source of Lake Avlan [Elmalı]), [Lake Işıklı], (Karadirek Stream [Upper Büyük Menderes basin]), (Köprüçay and Ilıca Stream), (Manavgat River basin, Lake Akgöl [Ereğli], Lake Çavuşcu [Ilgın] and Lake Suğla [Seydişehir]), (Köprüçay River basin [Bağıllı Village and Değirmenözü Stream]), (Kırkgöz Spring, Karamanlı Stream and tributaries of Düden canal in Antalya), and (Sultansazlığı [Kayseri]). is most similar to (Fig. 4). Itis distinguished from by having fewer branched pelvic fin rays (7, vs. 8 or 9), slightly fewer gill rakers in outer side of the first gill arch (7–8, rarely 9, vs. 8–9) and a longer caudal peduncle (caudal peduncle length 1.4–1.9 times caudal peduncle, vs. 1.3–1.4). It further differs from by having a shorter predorsal distance (52–57% SL, mean 55.0, vs. 57–61, mean 58.0), a shorter preanal distance (69–74% SL, mean 72.0, vs. 73–77, mean 74.5), a somewhat shorter head (head length 26–28 % SL, mean 26.8, vs. 27–31, mean 28.6), and narrower and relatively deeper hyomandibular bone (vs. wide and shallow) (see Figs 5a, b, c). Also and were compared by Principal Component Analysis (PCA). The PCA was performed in using 18 morphometric characters of the two species. The PCA clearly separated from (Fig. 6).
