We reexamined sexual dimorphism and female reproduction in the Many-Lined SunSkink Eutropis multifasciata from China.Our data confirm that adults are sexually dimorphic inbody size and shape,with males being the larger sex and larger in head size but shorter inabdomen length than females of the same snout-vent length (SVL).The rate at which head widthincreased with SVL was greater in males as opposed to the previous conclusion that the rate doesnot differ between the sexes.Matemal size was the main determinant of reproductive investment,with larger females generally producing more,as well as larger,offspring.Females produced up tonine offspring per litter as opposed to the previously reported 2-7.Most females gave birthbetween March and August,a time period longer than that (May- June) reported previously.Females with a higher fecundity tended to produce smaller offspring as opposed to the previousconclusion that females do not tradeoff offspring size against number.Litter size,neonate massand litter mass remained remarkably constant among years,and litter mass was more tightlyrelated to female body size than litter size or neonate mass.Smaller females could produce relatively heavier litters without a concomitant reduction in postpartum body condition.
