Reproductive Diversity

The exhibits exceptional reproductive diversity. T. alexanderae is biparental with facultative (can maintain through one only via ). Three uniparental (T. castum, T. merum, T. innuptum) reproduce via obligate thelytokous parthenogenesis. This system has been used as a model for studying the evolution of parthenogenesis and .

Systematic Importance

The large is divided into several clades and subclades based primarily on genital . This structure makes Trichadenotecnum significant for studies of morphological evolution and speciation in .
