Harnischia tenuitubercula Chaudhuri & Chattopadhyay, 1990: 158
Harnischia minuta Dutta & Chaudhuri, 1996: 272, Syn. n.
Harnischia ohmuraensis Kobayashi & Suzuki, 1999: 80, Syn. n.
Harnischia sibabecea Sasa, Sumita & Suzuki, 1999: 185, Syn. n.
Material examined. Holotype male labelled ‘ H. sibabecea Sasa, Sumita & Suzuki, 1999 (http://www.type.kahaku. go.jp/TypeDB/diptera/973)’; Holotype male labelled ‘ H. minuta Dutta & Chaudhuri, 1996 (Type no. B. U. Ent. 210)’; 2 males, India, West Bengal, Purba Barddhaman, Burdwan [23.22°N, 87.85°E], 16.ii.2022, Coll. N. Hazra; 2 males, India, West Bengal, Purba Barddhaman, Burdwan [23.2446° N, 87.8496° E], 18.iv.2022, Coll. B. Mukherjee; 3 males, India, West Bengal, Jalpaiguri [26.71°N, 88.76 °E], 07.iv.2022, Coll. P. Hui’.
Remarks. Harnischia ohmuraensis Kobayashi & Suzuki, 1999, H. sibabecea Sasa, Sumita & Suzuki, 1999, H. minuta Dutta & Chaudhuri, 1996 and H. tenuitubercula Chaudhuri & Chattopadhyay, 1990 have medially setose anal tergite, long gonostylus, broad anal point, and very small superior volsella. Kobayashi & Endo (2008) have synonymised H. sibabecea Sasa, Sumita & Suzuki, 1999 with H. ohmuraensis Kobayashi & Suzuki, 1999. Besides that, Chen et al. (2017) mentioned that H. tenuitubercula Chaudhuri & Chattopadhyay, 1990 and H. ohmuraensis Kobayashi & Suzuki, 1999 may be conspecific. After a considerate study of types, we come to conclusion that H. minuta Dutta & Chaudhuri, 1996 is also conspecific with H. sibabecea Sasa, Sumita & Suzuki, 1999. The original description of H. tenuitubercula was published in 1990 while descriptions of other species were made on 1996 and 1999 respectively. Therefore, the species H. minuta, H. ohmuraensis and H. sibabecea are junior synonyms of H. tenuitubercula.
