Treatment

Lamtostyla granulifera Foissner, 1997 View in CoL ( Table 3 View Table 3 ; Figs. 5 View Fig ,

6 View Fig )

Diagnosis. Cell size in vivo 110 × 50 μm on average, ellipsoidal, highly flexible ( Table 3 View Table 3 ; Fig. 6A, C View Fig ). Adoral zone about 27% of body length ( Table 3 View Table 3 ; Fig. 6A, I View Fig ). Contractile vacuole at left and somewhat ahead of midbody ( Figs. 5A View Fig , 6C View Fig ). Conspicuous cortical granules, colorless, 12 μm in diameter, arranged densely in rows on both cell surfaces ( Fig. 6E, J, K View Fig ). Two ellipsoidal macronuclear nodules with two to three micronuclei ( Fig. 5B View Fig ). Three frontal cirri; one buccal cirrus; four cirri in an amphisiellid median cirral row (ACR); three cirri left of the ACR; two pretransverse ventral cirri; and five enlarged transverse cirri ( Figs. 5B View Fig , 6H View Fig ). Three bipolar dorsal kineties, dorsal cilia in vivo 34 μm long; caudal cirri lacking ( Figs. 5C View Fig , 6F, I View Fig ).

Material examined. Obongri, Gangwondo province (38º20′N 128º30′E) collected by KangSan Kim in March, 2013 GoogleMaps .

Deposition. Protargolimpregnated specimens ( NIBR No. NIBRPR0000107161, NIBRPR0000107162) have been deposited in the National Institute of Biological Resources, Korea.

Habitat. Soil with twigs under a tree (pH 5).

Distribution. Venezuela, Australia, Japan, Thailand, Cape Town ( South Africa), Namibia, Korea.

Remarks. The genus Lamtostyla comprises three groups, i) the Lamtostyla lamottei group, ii) the L. longa group, and iii) the L. granulifera group ( Berger, 2008). The Lamtostyla lamottei group can be distinguished from other two Lamtostyla groups by having more than four amphisiellid median cirral row (vs. four or fewer than four in the L. granulifera group, and the L. longa group) ( Berger, 2008). The Lamtostyla granulifera group differs from the L. longa group in the number of dorsal kineties(3 vs. 5) ( Berger, 2008).

Lamtostyla granulifera and L. decorata , which belong to the L. granulifera group, share many characteristics, including short amphisiellid median cirral row; cortical granules present; and number of frontal cirri, buccal cirrus, marginal cirral rows, dorsal kineties, and macronuclear nodules ( Table 3 View Table 3 ) ( Berger, 2008). Lamtostyla granulifera is however different from L. decorata in the following features: cortical granules (12 μm in diameter, densely distributed on both surfaces vs. 0.3 μm in diameter, packed around the dorsal bristles); body shape (broadly elliptical vs. slender and elongate, somewhat twisted); and ratio of adoral zone length (2333% vs. 14 23%) ( Berger, 2008).

The Korean population of Lamtostyla granulifera shows high similarity to the Venezuelan population, except in body length (90130 μm in the Korean population vs. 125160 μm in the Venezuelan population) and in the number of left marginal cirri (3338 in the Korean population vs. 4252 in the Venezuelan population ( Table 3 View Table 3 ) ( Berger, 2008).
