Malmiana buthi n. sp. is described from the body and fins of the fluffy sculpin, Oligocottus snyderi, the tidepool sculpin, Oligocottus maculosus, and the woolly sculpin, Clinocottus analis, collected from tidepools at Horseshoe Cove on the Bodega Marine Reserve in Sonoma County, California. Prevalence of the leech was 32.6% on live-caught O. snyderi; mean intensity on O. snyderi was 3.3 leeches per fish, with a range from 1 to 7. The leech is not known to exceed 8 mm total length. The body is smooth, lacking papillae, tubercles, or pulsatile vesicles. Two pairs of crescentiform eyes are present on the oral sucker, and 1 pair of punctiform eyes occurs on the second annulus of the trachelosome. The caudal sucker has 14 small punctiform ocelli spaced evenly around the margin. The last 9 segments of the urosome have pairs of large punctiform ocelli both dorsally and ventrally. Body and caudal sucker pigmentation is uniformly reddish brown dorsally and ventrally with segental, lateral, unpigmented areas on both the urosome and trachelosome; pigmentation on the oral sucker is in the form of a cross. There are 5 pairs of testisacs; accessory gland cells on the atrial cornua and vector tissue are absent.
新种马尔米纳蛭（Malmiana buthi n. sp.）是根据从加利福尼亚州索诺马县博德加海洋保护区马蹄湾潮间带采集的绒毛杜父鱼（Oligocottus snyderi）、斑杜父鱼（Oligocottus maculosus）和肛杜父鱼（Clinocottus analis）的身体和鳍上发现的样本进行描述的。在活体捕获的斯氏杜父鱼上，这种水蛭的感染率为32.6%；每条斯氏杜父鱼身上的平均感染强度为3.3条水蛭，范围从1条到7条。已知这种水蛭的全长不超过8毫米。身体光滑，没有乳头、瘤或搏动泡。口吸盘上有两对新月形眼睛，气管体的第二环上有一对点状眼睛。尾吸盘边缘均匀分布着14个小的点状眼点。尾体的最后9节在背侧和腹侧都有成对的大型点状眼点。身体和尾吸盘的色素沉着在背侧和腹侧均为均匀的红棕色，尾体和气管体上有节段性、侧面无色素的区域；口吸盘上的色素沉着呈十字形。有5对睾丸囊；心房角和载体组织上没有附属腺细胞。
