Diagnosis SIF = 4BS-B(N)-3-0000.0000; fsp = 7.7.7; fSt = 2.2.n; fCx = 1.2.1; Ip = 500–700. Cheliceral blade with tricuspid cap only; galeal setae branched or nude; palpal claw 3-pronged; palpal tarsus with 4 branched setae and nude subterminala. Scutum with reduced posterior angles (peniscutum), with nasus (nasus absent in S. monosetosa ( Brown, 2006 ) comb. nov. ), 1AM, 2AL setae and flagelliform sensilla with basal barbs and distal branches; 2 PL setae extrascutal. Eyes 2 + 2; idiosomal setae numerous; two sternal setae between coxae I, two sternal setae between coxae II and many setae between coxae III; humeroventral setae situated between coxae II and III. Legs 7-segmented; pretarsala II absent; 1 microgenuala I, genualae I, II and III absent; tibiala III absent; coxae I and III with 1 seta, coxa II with 2 setae. Remarks The monotypic genus Anasuscuta Brown, 2009 differs from Straelensia in the absence of an anteromedian projection of scutum (nasus) only. This single case of reduction undoubtedly does not constitute a separate genus. I therefore regard Anasuscuta as a synonym of Straelensia .
