Revision of the spider genera Nilus O.

Figs 138–140 , 144–146 , 167 : 18 “ Dendrolycosa kochi ”,— Simon 1898a : 285 , 289. Blandin 1979 : 365 , fig. 34 (nomen nudum). Type material. Holotype , female ( MNHN ), Cap, sub Dendrolycosa kochi , E.S. 3190. Note. Simon noted on the label only “Cap!”. Simon (1898a: 289) and Blandin (1979: 365) gave as additional information “ Australie orientale”. Considering possible capes in the east half of Australia , the well known Cape York Peninsula seem to be a likely locality. Etymology. The species name is an abbreviation of the Zulu term “yeka ukwandisa abantu”, meaning “stop overpopulaton” and referring to the destructive power of human overpopulation and the disconcerting inactivity of politicians on the issue worldwide; term in apposition. Diagnosis. Small sized spiders with body length of 9.8 mm (females) and colour pattern B ( Figs 138–140 ). Female copulatory organ similar to D. cruciata and D. bairdi spec. nov. in having the anterior parts of the intromittent ducts extended into posterior half of the epigyne (restricted to anterior half in the otherwise similar D. songi ). Distinguished from D. cruciata , beside the different colour pattern, by the longer and mediad head of spermathecae, from D. bairdi spec. nov. by the slightly broken anterior margin of the carina and the first winding of the internal duct system shorter, i.e. not extending laterally beyond head of spermathecae ( Figs 144–146 ). Description. Female. PL 3.8, PW 3.0, AW 1.8, OL 6.0, OW 3.6. Eye diametres: AME 0.20, ALE 0.22, PME 0.17, PLE 0.18. Eye interdistances: AME–AME 0.12, AME–ALE 0.05, PME–PME 0.14, PME–PLE 0.27, AME– PME 0.20, ALE–PLE 0.33, clypeus AME 0.27, clypeus ALE 0.26. Leg and pedipalpus measurements: pedipalpus 4.5 (1.4, 0.6, 1.0, -, 1.5); leg I 14.0 (4.0, 1.6, 3.6, 3.3, 1.5); leg II 13.7 (4.0, 1.5, 3.5, 3.2, 1.5); leg III 11.0 (3.2, 1.3, 2.6, 2.7, 1.2); leg IV 14.4 (4.2, 1.4, 3.5, 3.9, 1.4); leg formula 4123. Spination: palp: femur 151, patella 120, tibia 1101, tarsus 1015; Femur I 435, II 435, III 535, IV 432; Patella I–IV 121, Tibia I–II 2228 , III–IV 2226 ; Metatarsus I–IV 3037 (with distal median ventral spine). Chelicerae with 3 anterior (median largest) and 4 equally sized posterior teeth. Palpal claw with 11 teeth, paired leg claws with 15–16 teeth, unpaired leg claw with one large primary tooth and two tiny secondary teeth. Copulatory organ as in diagnosis. Epigynal field wider than long, with one pair of slit sense organs antero-laterally, one included in epigynal field marginally. Central part of middle field with deep impression with pronounced anterior margin. Internal duct system with broad copulatory ducts. Base of spermathecae ellipsoid, not covered by copulatory ducts. Distal part of head of spermathecae broad ( Figs 144–146 ). Colour in ethanol (138–140): yellowish to reddish brown with colour pattern B ( Figs 138–140 ). Dorsal prosoma light reddish brown with 2 lateral white lines with an incision at the head-thorax-transition. An additional median white line is present in the anterior half. Chelicerae are slightly darker reddish brown than the dorsal shield of the prosoma. Appendages, sternum, labium and gnathocoxae yellowish brown without pattern. Opisthosoma bright brown, dorsally with 4 narrow and indistinct white lines in anterior half. Male : unknown. Distribution. Known only from the type locality, which might be in North Queensland: Cape York ( Fig. 167 : 18).
