Etymology

The specific name is a patronym in honour of the late Prof. Pontus Palmgren (1907–1993) who made a great contribution to studies of Finnish spiders.

Diagnosis

Dictyna palmgreni sp. n. resembles Dictyna major and Dictyna schmidti, from which it can be easily separated by the shape of the apical portion of the conductor (broadening and then abruptly tapering, not gradually tapering like in the other two species), the relatively short cymbium, the thick and spiralled epigynal ducts and also by the presence of a digitiform process (accessorial gland). In the male palp, the combination of short length and basal placement of the tibial apophysis also distinguishes it from the two other species.

Description

Male. Total length 2.63-3.00. Carapace: 1.10-1.30 long, 0.88-0.95 wide, cephalic part 0.60 wide, clypeus 0.14, chelicerae 0.79. Abdomen 1.75 long, 1.20 wide. Cymbium 0.69-0.79 long, 0.40-0.43 wide, length/width ratio 1.70-1.80. Leg I segments: femur 1.17, patella+tibia 1.36, metatarsus 0.86, tarsus 0.57. Carapace brown, cephalic part raised, well separated from thoracic part by ‘furrow’, cephalic portion with 5 longitudinal ‘furrows’ with sparse whitish hairs, thoracic part with radial stripes. Abdomen light to dark brown with dark grey-brownish pattern (Figs 1, 7), somewhat variable and sometimes with cardiac mark posteriorly trifid. Palp as in Figs 18-19, 22-23, tibia short, apophysis carrying ctenidia short (about 2 lengths of ctenidia) and positioned near base of tibia; conductor in one plain, upper arm of conductor abruptly cut, lower arm with bent thin tip directed retrolaterad.
Female. Total length 2.90-3.10. Carapace: 1.05-1.18 long, 0.91-0.94 wide, brown with dark-grey radial stripes, and light brown median band (behind posterior eye row). Cephalic portion with 5 longitudinal ‘furrows’ densely covered with whitish hairs. Clypeus 0.13, chelicerae 0.60. Leg I segments: femur 1.07, patella+tibia 1.14, metatarsus 0.69, tarsus 0.50. Abdomen light brownish with brown pattern as in Figs 2, 8-9, usually with cardiac mark posteriorly distinctly trifid, venter with median dark band. Epigyne as in Figs 28-30, 32-33 with thin septum and rather long margins. Vulvae with spiralled insemination ducts terminated by spiralled ‘receptacula’. ‘Receptacula’ with digitiform cylindrical accessorial gland.

Distribution

The new species is known across almost the entire northern Palaearctic: from Fennoscandia to Magadan, north to 68° in Finland, and southward to about 53° in Krasnoyarsk Province of Russia. To date, there have apparently been no documented adult specimens from Sweden (L. Jonsson & R. Pettersson pers. comm.), which are needed for the confirmation of its occurrence there.

Natural history

Adult females occur from late May throughout the summer, males from late May to at least the beginning of July. Finnish specimens have mainly been collected from stands dominated by Norway spruce (Picea abies), and often on moist ground (swampy forest or mires). At least to some extent the species is arboreal, but some specimens have been caught using pitfall-traps and some apparently live in open habitats.
