A surprisingly large number of European spider species have never been reliably rediscovered since their first description many decades ago. Most of these are probably synonymous with other species or unidentifiable, due to insufficient descriptions or missing type material. In this second part of a series on this topic, we discuss about 100 of these cases, focusing mainly on species described in the early 20th century by Pelegrín Franganillo Balboa and Gabor von Kolosváry, as well as a number of jumping spiders and various miscellaneous species. In most cases, the species turned out to be unidentifiable nomina dubia, but for some of them new synonymies could be established as follows: Alopecosa accentuata auct., nec (Latreille, 1817) = Alopecosa farinosa (Herman, 1879) syn. nov., comb. nov.; Alopecosa barbipes oreophila Simon, 1937 = Alopecosa farinosa (Herman, 1879) syn. nov., comb. nov.; Alopecosa mariae orientalis (Kolosváry, 1934) = Alopecosa mariae (Dahl, 1908) syn. nov.; Araneus angulatus afolius (Franganillo, 1909) and Araneus angulatus atricolor Simon, 1929 = Araneus angulatus Clerck, 1757 syn. nov.; Araneus angulatus castaneus (Franganillo, 1909) = Araneus pallidus (Olivier, 1789) syn. nov.; Araneus angulatus levifolius (Franganillo, 1909), Araneus angulatus niger (Franganillo, 1918) and Araneus angulatus nitidifolius (Franganillo, 1909) = Araneus angulatus Clerck, 1757 syn. nov.; Araneus angulatus pallidus (Franganillo, 1909), Araneus angulatus crucinceptus (Franganillo, 1909), Araneus angulatus fuscus (Franganillo, 1909) and Araneus angulatus iberoi (Franganillo, 1909) = Araneus pallidus (Olivier, 1789) syn. nov.; Araneus circe strandi (Kolosváry, 1935) = Araneus circe (Audouin, 1826) syn. nov.; Araneus diadematus nemorosus Simon, 1929 and Araneus diadematus soror (Simon, 1874) = Araneus diadematus Clerck, 1757 syn. nov.; Araneus pyrenaeus (Simon, 1874) = Araneus pallidus (Olivier, 1789) syn. nov.; Araneus sericinus (Roewer, 1942) = Aculepeira armida (Audouin, 1826) syn. nov.; Arctosa brevialva (Franganillo, 1913) = Arctosa villica (Lucas, 1846) syn. nov.; Arctosa cinerea (Franganillo, 1913) [nec Arctosa cinerea (Fabricius, 1777)] = Arctosa perita (Latreille, 1799) syn. nov.; Cresmatoneta eleonorae (Costa, 1883) and Cresmatoneta mutinensis orientalis (Strand, 1914) = Cresmatoneta mutinensis (Canestrini, 1868) syn. nov.; Cyclosa conica albifoliata Strand, 1907, Cyclosa conica defoliata Strand, 1907, Cyclosa conica leucomelas Strand, 1907, Cyclosa conica pyrenaica Strand, 1907, Cyclosa conica dimidiata Simon, 1929, Cyclosa conica rubricauda Simon, 1929 and Cyclosa conica triangulifera Simon, 1929 = Cyclosa conica (Pallas, 1772) syn. nov.; Dendryphantes lanipes C.L.

Cheiracanthium rupestre Herman, 1879, and Xysticus albomaculatus Kulczyński, 1891, both originally described from Hungary, are among the most rarely reported species of their genera in Europe. Here we report that both of these species have very close relationships to similarly uncommon species originally described from France at about the same time. The specimens currently considered as Cheiracanthium rupestre turn out to be very closely related to, but distinct from, Cheiracanthium striolatum Simon, 1878. However, the original description of C. rupestre does not match these specimens nor any other known species of Cheiracanthium. We therefore consider C. rupestre a nomen dubium and suggest that all previous records of this species after the original description actually refer to Cheiracanthium macedonicum Drensky, 1921. Xysticus albomaculatus, on the other hand, turns out to be a junior synonym of Bassaniana baudueri (Simon, 1877) syn. nov., expanding the range of this species considerably to the East and at the same time confirming that it is a genuine European species, rather than a recent immigrant from North America as previously suspected.

A new humped orb-weaver, Gibbaranea bruuni Lissner spec. nov., is described from specimens collected in Majorca, Spain. The new species is most closely related to two other western Palaearctic species, Gibbaranea gibbosa (Walckenaer, 1802) and Gibbaranea occidentalis Wunderlich, 1989. Araneus dromedarius cuculliger Simon, 1909 (= Gibbaranea bituberculata cuculliger) is synonymized with Gibbaranea bituberculata (Walckenaer, 1802), syn. nov. [ABSTRACT FROM AUTHOR]

The polysphinctine wasp Megaetaira madida (Haliday, 1838) is a koinobiont ecto-parasitoid of spiders of the genus Metellina. Under the influence of the parasitoid's final instar larva, the spider host M. merianae (Scopoli, 1763) built a three-dimensional web architecture, which differed considerably from the capturing orb web. The alteration of spider web behaviour induced by a parasitoid larva in this host-parasitoid pair is described for the first time. [ABSTRACT FROM AUTHOR]

The European spider of the year 2016, Cyclosa conica (Pallas, 1772), is presented. Its appearance and characteristics (e.g., ecology, habitat, phenology) are briefly described. The modality of the voting is given as well as numerous links to the supporting societies and to distribution maps. [ABSTRACT FROM AUTHOR]

Amblyolpium goldastehae spec. nov., is described and illustrated on the basis of two males collected from western Iran. Its ability to live in a dry and xerotherme habitat is also discussed. [ABSTRACT FROM AUTHOR]
