Trichoceridae ( Fig. 4 )

The family comprises more than 160 extant species worldwide, grouped into two subfamilies and six genera ( Krzemińska 2021). Studies by Krzemińska & Young (1992) have contributed to the knowledge of this family in Chile with eight species grouped into the genera Nothotrichocera Krzemińska , Trichocera Meigen and Zedura Krzemińska. Recently , T. maculipennis has been reported for the first time in Navarino Island and Punta Arenas city, adding a new invasive species for the Chilean territory ( Contador et al., 2024).

2. Suborder Psychodomorpha

Bertone et al. (2008) and Wiegmann et al. (2011) recovered this suborder composed of Blephariceridae , Psychodidae , and Tanyderidae using molecular and morphological analysis to estimate relationships among families. Brown et al. (2009) follow Wood & Borkent (1989) and include Psychodidae , Trichoceridae , Perissommatidae , Anisopodidae , Scatopsidae , and Canthyloscelidae , based on larval features (head capsule and mouthparts, mandibular movement, maxillary palps, for example). This arrangement differs from that proposed by Hennig (1973), which was based on the shared coalescence of meron with katepimeron.
