Upperside dark olive-brown; cilia pale brownish-cinereous; forewing with a single small, pale white, semi-diaphanous spot at upper end of the cell, three contiguous subapical spots, another below these; and two larger spots below obliquely on the disc, a small spot also very indistinctly visible on middle of submedian vein; hindwing without spots. Underside greyish olive-brown; spots slightly more prominent than above; hindwing with a discal series of five small somewhat indistinct white spots.
Salween, Moulmein (Lt. Bevan). A male specimen of this species from Calcutta collected by the late Mr. Atkinson is in the collection of Dr. O. Staudinger. Also recorded from Karachi, Mhow, Poona and Bombay (Swinhoe); Calcutta (de Niceville); Orissa (Taylor); Nilgiris (Hampson). Mr. Elwes also states that he has specimens from Mandi, N.-W.

擬秈弄蝶（學名：Pseudoborbo bevani，英文俗名：Bevan's Swift）又名假禾弄蝶、小紋褐弄蝶、假秈挵蝶、擬秈弄蝶、偽禾弄蝶，是屬於弄蝶亞科刺脛弄蝶族的一種蝴蝶。是擬秈弄蝶屬（學名：Pseudoborbo）的唯一一種，是一個單型分類[1]。分佈於東洋界至澳新界，模式產地為緬甸毛淡棉[2]。幼蟲的寄主為農作物[3]，亦因此被視作害蟲。
擬秈弄蝶屬曾是個有爭議性的分類，有學者承認此屬[4][5][6]，否認的則歸之入秈弄蝶屬作為異名[7][8][9]，但更新的研究發現她們是兩個不同的演化支，不能以多系群建立有效的分類，而且形態學上亦有不同之處，因此擬秈弄蝶被視為獨立一屬[1]。

雄蝶前翅長13.5-17.0毫米，前翅翅型近鈍角三角形，外緣近頂角處微突出；後翅型近等邊三角形，臀角處突出不很明顯。翅正面底色褐色，反面底色偏黃褐色。兩翅斑紋多變，半透明小白斑斑紋非常細小。兩翅緣毛為淡褐色。前翅正面亞頂角區R3-R5室斑各具1個點狀小斑；中域通常僅有M3和Cu1室兩個小斑，極少數個體M1和M2室也具小斑；僅有1個上中室斑或者無；Cu2室中域通常無斑，偶爾會具1個點狀小斑。前翅反面斑紋同正面。後翅正面無斑。後翅反面Rs、 M3及Cu1室各具1個小斑，並呈圓弧狀排列，偶爾M2和M1室也會有1個點狀斑，有些個體後翅反面完全無斑。
雌蝶體型較大，前翅長度同雄蝶，翅型較雄蝶圓，顏色略淺，前翅顏色較均勻，白斑較多，兩性翅膀斑紋相似[6][10]。
雄外生殖器背兜背部無突起；鉤形突基本與背兜等長，末端不二分，基部具向上的角狀突起；囊形突較短，末端收縮變細；抱器端粗大，外緣上半部具鋸齒狀突起，端部向內側突出；陽莖長而較直，超過2倍抱器的長度，內具長條形的角狀突；陽莖末端左側具細長的指狀突起，右側陽莖端膜上具1個細長的骨質化指狀突起。
雌外生殖器的前陰片和後陰片骨質化不明顯；囊導管長且骨質化強烈，中部具折痕，交配囊體圓球形[10]。
