  Taxonomy

  
  

  The holotype of Botys poeyalis, Boisduval 1833a: 118 is from Mauritius (Bourbon Is.) TL Reunion] Comb. n. to Cnaphalocrocis Lederer 1863c (Shaffer et al. 1996).
  
  Syn. Asopia venilialis Walker, 1859c: 373. TL Australia (Q.). Syn. n. (Marion, 1955: 76). It is the TS of Dolicisticha Meyrick, 1884b: 304;
  
  syn. Botys marisalis Walker, 1859d: 717 TL Sarawak (Kuching);
  
  syn. Marasmia cicatricosa Lederer, 1863c: 386 pl. 12, fig. 8. TL Java;
  
  syn. Marasmia rectistrigosa Snellen, 1872: 92, syn. n. (Shaffer et al. 1996) The male holotype from [New] Guinea is in Leiden;
  
  syn. Botys minutalis Mabille,1880d: 339. TL Madagascar. Syn. n. (Marion, 1955: 78).
  
  syn. Marasmia hampsoni Rothschild, 1921: 227. TL W. Nigeria (Jigawa) syn. n. (Shaffer et al. 1996);
  
  syn Marasmia procopia Nye (MS name). This was considered conspecific with C. poeyalis Boisduval and also C. ruralis Walker 1959d: 666 (TL Sri Lanka) by Bradley (1987) (see Bradley, 1981: 327 where it is considered a good sp.).
  
  syn Asopia venialis Walker 1859c: 373, TL Australia (Moreton Bay) (TS of Dolichosticha Meyrick, 1884: 304).
  
  Nec syn. Lasiacme mimica Warren,1896: 177, from India, Khasia Hills [Meghalaya] The holotype is in the NHM. It was also considered syn. in Lepindex but Shaffer notes on the same LepIndex card 'A good sp.' Here we treat it as such.
  
  A series in the NHMK under the name C. procopia (Nye Ms name) closely resembles C. poeyalis but as the brown is much more intense this may be a var. (see illustration 2).

  Description

  
  

  Wing length: 7.5mm. The 'lesser rice-leafroller' adult is a pale beige coloured moth with submedian and postmedian lines across the wings. The post median line is displaced proximally to the rear of the FW like Cnaphalocrocis patnalis and C. poeyalis but unlike C. medinalis. In the male these lines are obscured centrally by a dark brown discal scale tuft. There is a broad dark brown submarginal band. The FW costa has a series of dark brown marks like some other Cnaphalocrocis spp. The abdomen is a creamy colour with abdominal segment 8 with basal band of black scales and distal band of light brown to orange scales, abdominal segment 9 with median longitudinal stripe of black scales bordered by white scales. C. mimica (Warren, 1896) has much wider, dark submarginal bands on FW & HW. C. mimica (Warren, 1896) has much wider bands on the FW & HW.

  Life History & Pest Status

  
  

  The larva feeds on leaves of grasses and sedges. They are a pest on rice plants and soy plants. The caterpillar rolls up a leaf to shelter in during the day. At maturity, the caterpillar pupates in a folded leaf of the food plant.
