Dacochile microsoma Poinar and Brown, 2004

Figures 11-12

Remarks. Dacochile microsoma is described from Cretaceous Burmese amber and is among the smaller species of Nannotanyderinae ; however, with a wing length of 2.8 mm, it is significantly larger than N. ansorgei . In the wing, the anal lobe is greatly reduced and vein Sc terminates at a point corresponding to one third the length of vein Rs ( Figure 12.1 ). Woodley (2005) discussed the placement of Dacochile in Tanyderidae and stated that this genus should be transferred to Psychodidae . Despite a detailed explanation and justification for placing Dacochile in Tanyderidae , and the description of a new specimen by Poinar and Brown (2006), the taxonomic placement of this genus remained uncertain. Subsequently, Krzemiński et al. (2013a) described from Myanmar amber a male of D. microsoma showing pertinent characters that confirm its classification as a tanyderid.
