New species in the family Ctenidae Keyserling, 1877 from high altitude habitats in Myanmar, with the first case of penetration of the female’s cuticle by a male in the RTA-clade (Arachnida: Araneae: Ctenidae) Author Jäger, Peter Author Minn, Myin Zu text Zootaxa 2015 3994 2 235 252 journal article 10.11646/zootaxa.3994.2.4 afcac252-ff9b-49f0-9c58-b35c9d4d80c2 1175-5326 235688 2E6312C0-FE02-4318-ADC9-1D37F714D0AC Ctenus spec. Figs 44–50 Material examined. MYANMAR : Chin State : 1 male , 1 female , above Kampetlet, above Oasis Mountain Resort, 21°11'54.14''N , 94°02'16.78''E , 1752 m , disturbed secondary forest, at night, by hand, P. Jäger leg. 18 May 2014 ( SMF ). FIGURES 44–47 Ctenus spec. , male from Mt Victoria, Myanmar, palp (44 prolateral; 45 ventral; 46 retrolateral; 47 embolus tip, ventral). FIGURES 48–50 Ctenus spec. , female from Mt Victoria, Myanmar, copulatory organ (48 epigyne, ventral; 49 epigyne, posterior; 50 vulva, dorsal). I + II—two chambers of spermathecae, chamber II functionally between chamber I and fertilisation duct. Note. This male exhibited a different distal tip of RTA than the typical C. natmataung spec. nov. ( Figs 45–46 ). A malformation seems to be unlikely since both palps show the same shape of the RTA tip. Other palpal structures ( Figs 44–47 ) or copulatory organs of the female ( Figs 48–50 ) collected with the male as well as colouration of both sexes ( Figs 22–25 ) are absolutely congruent with those character states in C. natmataung spec. nov. So far, it cannot be decided whether these specimens (especially the male) are conspecific with C. natmataung spec. nov. and the RTA tip represents a strong intraspecific variation or whether it belongs to a different species. Body length: male 9.9, female 15.3.
