(Araneae, Salticidae) (Dr N. I. Platnick); CNC=Canadian National Collec- tion, Ottawa, Canada (Dr C. D. Dondale); MCZ= Dmitri V. Logunov Museum of Comparative Zoology, Harvard University, Siberian Zoological Museum, Cambridge, USA (Mrs L. Leibensperger and Dr G.

The sequence of leg segment measurements is as and follows: femur+patella+tibia+metatarsus+tarsus. The Seppo Koponen following abbreviations are used in the text and in Zoological Museum, Centre for Biodiversity, the table: AME=anterior median eyes, ap=apical, University of Turku, FIN-20014 Turku, Finland d=dorsal, Fm=femur, Mt=metatarsus, PLE=posterior lateral eyes, pr=prolateral, Pt=patella, rt=retrolateral, Tb=tibia, v=ventral. For the leg spination the system Summary adopted is that used by Ono (1988). All measurements Phlegra hentzi (Marx, 1890) comb. n. is removed from the are in mm. synonymy of P. fasciata (Hahn, 1826) and redescribed on the basis of both old and newly collected material from North America. An up-to-date map of its distribution is (Marx, 1890) comb. n. (Figs. 1–2, 4–7, also provided. Phlegra hentzi Map 1) Introduction Attus leopardus Hentz, 1846: 359–360, pl. 21, fig. 21 ( 8 holotype considered lost, not examined; name preoccupied); type For along time, most researchers have treated locality: USA, Alabama. Phlegra leopardus (Hentz, 1846) as ajunior synonym of Aelurops fasciatus:Emerton, 1875: 130 (synonymised Attus leopardus Hentz, 1846 with Hahn, 1826). Phlegra fasciata (Hahn, 1826), although this synonymy Attus fasciatus Attus hentzi Marx, 1890: 578 (replacement name for A. leopardus is obviously incorrect. Hentz (1846) described anew Hentz). species, Attus leopardus,from USA (Alabama), but this Phlegra leopardus:Emerton, 1891: 242, pl. 21, fig. 1a–d ( 78); Peckham specific name turned out to be ajunior primary homo- &Peckham, 1909: 521, pl. 42, fig. 6(8 ); Banks, 1910: 69. nym of Attus leopardus Walckenaer, 1837 [=Pelegrina Phlegra fasciata:Chickering, 1944: 203, figs. 122–125 ( 78); Chamberlin &Ivie, 1944: 213 ( ); Kaston, 1948: 460–461, pl. proterva (Walckenaer, 1837); see Prószyn´ski (1990)]. 7 90, figs. 1669–1674 ( 78); Roewer, 1955: 1140–1141; Bonnet, This fact was first indicated by Marx (1890), who 1958: 3594–3596; Richman &Cutler, 1978: 97, 103; Kaston, correctly proposed anew replacement name for this 1981: 460–461, pl. 90, figs. 1669–1674 ( 78); Cutler, 1988: 424; taxon, Attus hentzi.However, subsequent authors Platnick, 1989: 613; 1993: 799; 1998: 924; Guarisco et al., (Emerton, 1891; Peckham &Peckham, 1909; Banks, 2001: 8. 1910) did not accept this proposal and continued to Diagnosis:The species has for along time been use the invalid name Phlegra leopardus.Later, without confused with Phlegra fasciata,but males can be readily any argumentation, Chickering (1944) and subsequent separated from it by the stronger (more massive) embo- authors (Chamberlin &Ivie, 1944; Kaston, 1948, etc.) lus (cf. Figs. 4and 10), the pointed and curved tibial began to interpret the North American species as apophysis (rather than bilobate as in fasciata:cf. Figs. 2 Phlegra fasciata,ignoring the fact that although and 3), and by the clypeus being densely covered with Emerton (1875) first regarded P. leopardus and P. light/turquoise blue scales (cf. Figs. 7and 8). Females of fasciata as the same species, he had later (Emerton, P. hentzi can be easily distinguished by the clearly 1891) changed his opinion and treated P. leopardus as a bilobate epigyne overhanging the epigastric furrow (cf. valid species (see Bonnet, 1958: 3594, footnote). This Figs. 5and 9), and by the diff erent arrangement of taxonomic case has never been thoroughly studied and the spermathecal loops (cf. Fig. 6and Logunov, 1996: therefore the name Phlegra fasciata has been errone- fig. 25). ously assigned to the species occurring in the USA (see Distribution:Mainly eastern half of North America, Richman &Cutler, 1978), while the name Attus hentzi approximately to the east of 100$ W(Map 1). has been either omitted (see Prószyn´ski, 1990), or has Description: Male (Texas: Raven Ranch): Carapace been included in the synonymy list of Phlegra fasciata in 2.88 long, 1.95 wide, 1.05 high at PLE.
