Taiyutyla napa Shear, 1971

Fig. 22

Taiyutyla napa Shear 1971: 87 . Type locality: California , Napa Co., Mt. St. Helena, male holotype and two female paratypes ( AMNH) .

New record: California , Napa Co., Mt. St. Helena, estimated coordinates taken from the Mt. St. Helena Trail Head along SR-29, elev. 715 m., 38.6523°N, - 122.5998°W, 13 March 1962, J. S. Buckett, M. E. Irwin, m f ( EMEC) .

Notes: These specimens are topotypical. The scanning electron micrograph ( Fig. 22 ) shows many details not seen using optical microscopes and not reported in the original description ( Shear 1971). Figure 22 illustrates, in posterior view, the anterior (ag) and posterior (pg) gonopods. The ventral part of the T-shaped branch (T) of the posterior gonopod coxite is evidently absent, so the coxite somewhat resembles those of species of Bifurcatella , n. gen., but the anterior gonopod does not. For the time being, this species is better accommodated in Taiyutyla . Note the secretion (sec) emerging from a pore in the anterior gonopod.
