  First chance to see: New jumping-spider species from Batanta, Indonesia (Araneae, Salticidae, Euophryini) Abstract The first spider records of Batanta, Birie, and Arefi islands, Raja Ampat, Indonesia are presented in this study. Three new species in the genus Canama Simon, 1903, Canama horobi sp. nov . (male), Canama limagigi sp. nov . (male) and Canama wanita sp. nov . (female) are described. Two Indonesian salticids, originally placed in Bathippus Thorell, 1892 and known from their original descriptions only, Bathippus dentiferellus Strand, 1911 and Bathippus seltuttensis Strand, 1911, are redescribed and illustrated. Due to their morphological similarity to the type species, three new combinations have been proposed: Canama dentiferellus (Strand, 1911), comb. nov ., Canama seltuttensis (Strand, 1911), comb. nov . and Canama dilanians (Thorell, 1881), comb. nov . To confirm the phylogenetic placement of the new species, we carried out a small phylogenetic anal...

Two new species of the Cybaeus hiroshimaensis-group (Araneae: Cybaeidae) from the northern Hida Mountains, Japan

Abstract

Two small-sized species of the spider genus Cybaeus L. Koch, 1868, C. pycnothrix sp. nov. and C. tateyamensis sp. nov., are described based on both sexes from the Tateyama Mountain Range in the Hida Mountains, central Honshu, Japan. Phylogenetic analyses using nuclear internal transcribed spacer 1, 28S rRNA, and histone H3 markers revealed that the two new species are members of the monophyletic Japanese Cybaeus hiroshimaensis-group. Both new species conform to the morphological diagnosis of the hiroshimaensis-group — small body size and a short, thick male palp — and build two-opening retreats, indicating that retreat architecture in the group varies and encompasses both two- and three-opening forms.
