Etymology. The Latin adjective “mollis” (-ie, -e), meaning gentle.
Holotype. Specimen in Figure 18.11-12 View FIGURE 18 from the sample YDY05-01.
Paratype. Specimen in Figure 18.9-10 View FIGURE 18 from the sample YDY05-01.
Description. Test is ellipsoid to slender ellipsoid in shape and consists of a pylodiscid-type central combination, one or two pseudo-concentric shells, and an outermost coverage shell. The central combination is obliquely oriented to the shorter axis of the test. The 1st pseudo-concentric shell is oblong in shape (the ratio of the longest axis (Ug-axis in Type 2 coordinates) to the shortest axis is 1.3–1.5) with large pores (3.6–7.8 μm in diameter). Large spaces exist between the central combination and the 1st pseudo-concentric shell, and these two parts are connected with two beams parallel to the Lt-axis direction, at least two apical rods, and at least three basal rods. The outermost coverage shell has a relatively rough surface. Space between the 1st pseudo-concentric shell and the outermost coverage shell is present throughout. A bore pylome is present on one side of the outermost coverage shell.
Remarks. Larcopyle molle n. sp. differs from both Larcopyle variabile ( Dreyer, 1889) and Larcopyle eccentricanoides n. sp. in that the latter two species have irregular contact between the outermost coverage shell and the 2nd pseudo-concentric shell and narrow space between the central combination and the 1st pseudo-concentric shell.
Dimensions. Based on the holotype specimen. The width of the central combination (S1a): 14.3 μm; The length of the S1a-girdle: 15.3 μm; The length of the 1st pseudo-concentric shell: 59.3 μm; The length and width of the outermost coverage shell: 97.8 μm and 55.3 μm. The length ratio to the width of the outermost coverage shell: ca. 1.8.
