Untilnow, only U. durandi (Latreille, 1809) is known from Turkey. Here, we record for thefirst time from Turkey U. thaleri Rheims, Santos & van Harten, 2007 which wasoriginally described from Yemen. All available information on these little knownOecobiidae species is presented along with comments on their distribution pattern inTurkey. Also, some characteristic features with photographs of genitalia and generalhabitus of both sexes are presented.Keywords: Uroctea durandi, Uroctea thaleri, Oecobiidae, Spiders, Turkey.IntroductionThe old world genus Uroctea Dufour, 1820 is one of the six genera currentlybelonging to the family Oecobiidae. It was described by the French naturalist Léon JeanMarie Dufour in 1820 and includes 18 species which are predominantly distributed in thePalaearctic region (Platnick, 2009).Roewer (1959) first mentioned Uroctea durandi (Latreille, 1809) from Adanaprovince of Turkey. However, neither a specimen nor a figure was shown in his paper,this makes comparison with other species impossible. Afterwards, Topçu et al. (2006)have been reported U. durandi from Adana, Mersin and Niğde provinces.In the present study, U. durandi (Latreille, 1809) and U. thaleri Rheims, Santos &van Harten, 2007 of genus Uroctea were studied. U. thaleri is recorded for the first timein the Turkish araneofauna.

Material and methodsSpecimens from the following institutions were examined/cited. Abbreviations,cities and curators are as follows:MNHN Muséum National d Histoire Naturelle, Paris, France (C. Rollard);MTAS Museum of Turkish Arachnological Society, Ankara, Turkey (K.B. Kunt);OUMNH Oxford University Museum of Natural History, Oxford, England (Z. Simmons);ZMB Museum für Naturkunde der Humboldt-Universität, Berlin, Germany (J. Dunlop).Specimens were photographed using an HP Photosmart R707 camera attached toan Euromex ZE.1654 stereomicroscope. For SEM photographs, the materials wereexamined at an accelerating voltage of 15 kv under Jeol JSM 6360 LV Scanning ElectronMicroscope, and the electron micrographs were recorded.All measurements are in millimetres. Epigynes were dissected and submerged in5% KOH to study internal structures.ResultsFamily Oecobiidae Blackwall, 1862Genus Uroctea Dufour, 1820Dufour, Ann. gén. sci. phys. v, p. 198, 1820;Simon, Hist.

It is known in Andorra,Bulgaria, Croatia, France, Greece, Italy, Macedonia, Portuguese, Slovenia and Spain(Helsdingen, 2006). It has been also recorded from England (Selden, 2003). U. durandi ismainly distributed in the Aegean and Mediterranean regions of Turkey (Map 1). Themorphological and genitalia features of our samples collected from Marmara and EastAnatolian region are the same of our samples collected from Aegean and Mediterraneanregions. Furthermore, no differences have been observed between Turkish populationsamples and type material.Natural History: Specimens were collected in their tent-like webs under stones from dryareas. We observed the remains of millipedes in their webs (Fig. 2).94

Comments: According to Rheims et al. (2007), "The males of Uroctea thaleri can bedistinguished from other species of the genus by the extremely wide tegular apophysis 1and by the long and apically rounded proximal tegular lobe. Females can be distinguishedby the long and parallel insemination and fertilization ducts, both describing a medianloop between the epigynal plate and the spermathecae. An additional diagnostic characteris a blind ending duct emerging basally from the fertilization ducts."Fig. 4: Male palp of U. thaleri (MTAS/Oec: 0806). A, D. Left palp, prolateral view.B. Embolus C. Right palp, prolateral view. A-C: SEM. (D, Scale line 0.5 mm).Abbreviations: E embolus; TA1–3 tegular apophyses; TL tegular lobe.Unfortunately, despite of our efforts, we could not examine the type specimens ofU. thaleri to make comparison between them and our samples. After examining theillustrations of the type specimens of U. thaleri presented by Rheims et al. (2007, Figs. 58, 11-12), there is no doubt that our Uroctea samples collected from East Mediterraneanand South East Anatolian region belong to U. thaleri. Their abdomens are dorsally darkgrey with creamy spots or marks (Fig. 3) and they have the same genitalia of male (Fig.4) and female (Fig. 5).U. thaleri was described by Rheims et al. (2007) from Yemen. However, it hasalso been recorded from India, Iran and Israel. In fact, it is not unexpected to find U.thaleri in Turkey, taking in consideration its known distribution range. However, therecord of U. thaleri from Israel and the seven creamy abdominal spots of juvenileTurkish samples (Fig. 3C) led us to ask a question: Do our U. thaleri specimens belong toU. septempunctata species which description was based on juvenile specimens by O.P.Cambridge (1872) from Palestine and Syria (Lebanon)?In 1872, O.P.-Cambridge described U. septempunctata as follows: “This speciesis similar to C. limbata in form and structure [Fig. 6A, B]. The whole of the fore part ofthe spider is yellow, but of a clearer, brighter hue than in that species; the abdomen is dullblack, but the upperside, instead of being surrounded by a continuous border of a whitishyellow colour, has in its place a marginal row of seven large yellow spots; four of these98

form nearly a square on its fore half, and the three others are in a triangle above thespinners, the apex directed backwards [Fig. 6C]. It is possible that in some examplesthese spots may become nearly confluent, and so form a band very similar to that on theabdomen of C. limbata; but still some other specific characters, such as a slight differencein the relative position of the eyes, and the less dense armature of the legs with hairs,bristles, and fine spines, seem to show that it is quite distinct from that species, of whichsix adult examples found in 1864 at Alexandria (Egypt) presented no variation whateverin the uniformity and continuity of the abdominal border.An immature male was found at Jerusalem under a piece of detached rock in thevalley of Hinnom, an immature female in a similar situation near Ain Ata, and another atTiberias.”Fig. 5: Epigyne of U. thaleri (MTAS/Oec: 0805). A. Ventral view. B. Internal genitalia,dorsal view. (Scale line 0.5 mm). C. Ditto, SEM, arrow shows blind ending duct.After O.P.-Cambridge’s description, the Italian arachnologist Pietro Pavesi (1895)published a short description, without genitalia illustrations, based on an adult femalecollected from Hermon Mountain in Palestine/Israel. Pavesi (1895) mentioned that hisadult female specimen is deposited in “Museo di Zoologia e Anatomia Comparata”, butwe learned that the invertebrate collection of this museum was moved to “MuseoRegionale di Scienze Naturali, Torino” many years ago. Unfortunately, we could not geta response to our correspondence with the Museum of Torino.Comparing our U. thaleri specimens with a type specimen of U. septempunctata(OUMNH) and the Holotype of U. limbata (C.L. Koch, 1843) (ZMB), we observed thatour Turkish samples of U. thaleri are similar to the first species. Especially, theabdominal pattern with seven spots of juvenile U. thaleri and U. septempunctata samples99

(Fig. 3C, 6C). Also, arrangement of the eyes and position of the spines and hairs on thelegs are similar in these two species.As a result, we suggest that U. thaleri and U. septempunctata may be the samespecies. We could not obtain a new comparison material of U. septempunctata fromIsrael to be able to reach to definite result. But, we believe that our suggestions andfindings will make some contribution to revisional studies and resolve some taxonomicalproblems of this genus in the future.Natural History: The habitat selection and web designs are similar to that of U. durandi.They run very quickly when disturbed.Fig. 6: Uroctea limbata (C.L.
