Genital pore median, behind cesophageal bifurcation, at junction of anterior and middle thirds of body length. Genital sac

Testes roundish in outline, postovarial, one immediately but
somewhat obliquely behind the other; anterior testis 0.26, posterior testis 0.24 millimeter in diameter. Seminal vesicle median, between gonotyl and ovary, 0.42 by 0.13 millimeter, bent
