Stigmaeopsis

description: Due to the addition of two new species, the key to the <i>Stigmaeopsis</i> species (for adult female) in Saito et al. (2 0 1 8) should be changed as follows: 1. Length of setae <i>d</i> 1 shorter than (or similar to) distance between bases of <i>d</i> 1 setae members.......... 2 - Length of setae <i>d</i> 1 longer than distance between bases of <i>d</i> 1 setae............................... 9 2. Length of setae <i>d</i> 1 shorter than (or similar to) distance between bases of <i>d</i> 1 and <i>e</i> 1 setae............ 3 - Length of setae <i>d</i> 1 longer than distance between bases of <i>d</i> 1 and <i>e</i> 1 setae......................... 5 3. Length of setae <i>d</i> 2 longer than distance between bases of <i>d</i> 1 and <i>d</i> 2 setae............................................................................... <i>Stigmaeopsis tegmentalis</i> Saito &amp; Lin - Length of seta <i>d</i> 2 shorter than distance between bases of <i>d</i> 1 and <i>d</i> 2 setae......................... 4 4. Length of setae <i>e</i> 1 similar to distance between bases of <i>e</i> 1 and <i>f</i> 1 setae................................................................................... <i>Stigmaeopsis saharai</i> Saito &amp; Mori - Length of setae <i>e</i> 1 much longer than distance between bases of <i>e</i> 1 and <i>f</i> 1 setae............................................................................ <i>Stigmaeopsis temporalis</i> Saito &amp; Ito 5. Length of seta <i>e</i> 1 similar to distance between bases of <i>e</i> 1 and <i>e</i> 2 setae.................................................................................. <i>Stigmaeopsis takahashii</i> Saito &amp; Mori - Length of seta <i>e</i> 1 longer than distance between bases of <i>e</i> 1 and <i>e</i> 2 setae.......................... 6 6. Length of setae <i>d</i> 1 similar to distance between bases of <i>d</i> 1 and <i>f</i> 1 setae.......................... 7 - Length of setae <i>d</i> 1 shorter than distance between bases of <i>d</i> 1 and <i>f</i> 1 setae......................... 8 7. Length of <i>c</i> 1 much shorter than the distance between the bases of <i>c</i> 1 and <i>c</i> 3 setae................................................................ <i>Stigmaeopsis formosa</i> * Saito, Sato &amp; Chao, n. sp. - Length of <i>c</i> 1 is almost the same as the distance between the bases of <i>c</i> 1 and <i>c</i> 3 setae....................................................................... <i>Stigmaeopsis sabelisi</i> * Saito &amp; Sato 8. Length of seta <i>d</i> 1 shorter than distance between bases of <i>d</i> 1 and <i>e</i> 2 setae............................................................................ <i>Stigmaeopsis tenuinidus</i> (Zhang &amp; Zhang) - Length of setae <i>d</i> 1 longer than distance between bases of <i>d</i> 1 and <i>e</i> 2 setae............................................................................... <i>Stigmaeopsis malkovskii</i> * (Wainstein) 9. Distance between bases of <i>e</i> 1 setae similar to that between bases of <i>d</i> 1 setae........................................................................... <i>Stigmaeopsis nanjingensis</i> (Ma &amp; Yuan) - Distance between bases of <i>e</i> 1 setae shorter than that between bases of <i>d</i> 1 setae.................... 10 10. Length of setae <i>d</i> 1 shorter than (or similar to) distance between bases of <i>d</i> 1 and <i>f</i> 2 setae............ 11 - Length of setae <i>d</i> 1 longer than distance between bases of <i>d</i> 1 and <i>f</i> 2 setae........................ 13 11. Distance between bases of <i>c</i> 2 setae similar to that between bases of <i>d</i> 2 setae..................... 12 - Distance between bases of <i>c</i> 2 longer than that between bases of <i>d</i> 2 setae..................................................................................... <i>Stigmaeopsis miscanthi</i> *(Saito) 12. Length of setae <i>d</i> 2 shorter than (or similar to) distance between bases of <i>d</i> 1 and <i>d</i> 2 setae.......................................................................... <i>Stigmaeopsis celarius</i> Banks - Length of setae <i>d</i> 2 longer than distance between bases of <i>d</i> 1 and <i>d</i> 2 setae............................................................................. <i>Stigmaeopsis continentalis</i> * Saito &amp; Lin 13. Mediodorsal striae (central part of quadrilateral forming <i>c</i> 1 and <i>d</i> 1 setae bases) transverse........................................................... <i>Stigmaeopsis meghalayensis</i> (Gupta &amp; Gupta) - Mediodorsal striae (central part of quadrilateral forming <i>c</i> 1 and <i>d</i> 1 setae bases) longitudinal........ 14 14. Distance between bases of <i>c</i> 2 longer than that between bases of <i>d</i> 2 setae.... <i>Stigmaeopsis longus</i> (Saito) - Distance between bases of <i>c</i> 2 almost the same as that between bases of <i>d</i> 2 setae..................................................... <i>Stigmaeopsis inthanonsis*</i> Saito, Kongchuensin &amp; Sahara, n. sp. Thus 15 species are now involved in the genus, <i>Stigmaeopsis</i>. The species marked with asterisks inhabit <i>Miscanthus</i> grasses and reedgrass (Poaceae), whereas all others inhabit Bambusoideae (Poaceae) plants.
