Baeotendipes noctivaga

Author: (Kieffer, 1911)

Diagnosis (Material in coll. ZSM)
Exuviae 8.1, 8.6mm long (n=2).
Cephalothorax: Cephalic tubercles LxB 100x100µm (n=1) (101j.jpg). Frontal setae 100, 105µm long (n=2). Thoracic horn much branched. Basal ring of thoracic horn 100x60, 105x63µm (n=2); tracheal patch 73x23µm; 10 tracheoles across (n=1).
Abdomen: Hook row II entire, length of row 0.61x width tergite (n=1); hooks 83, 84 (n=2) (101i.jpg). Armament of tergites II-VI in the form of an undivided, strongly "waisted" patch of strong points, e.g. on IV cut back just in front of the posterior transverse band to level seta D5; posterior transverse bands increasing in extent laterally from tergite II to VI (101i.jpg). Point patches increase in extent from tergite II to V, but on VI the patch is more or less reduced. Apical spinule patches of paratergites V and VI present. Sternites I and VI unarmed. Sternites III and IV without anterior transverse band or longitudinal lateral bands of shagreen. Parasternite II shagreened. Comb of segment VIII with 1-4 stout teeth (n=2), comb on the end of an elongate ventral cuticular mound which exceeds appreciably the apico-lateral corner of the segment (101k.jpg).
Anal segment: Fringe of anal lobe with 79, 85 taeniae (n=2).

Note: As pointed out by Pinder and Reiss, in Wiederholm, 1986a, there seems little cause on pupal grounds to treat this genus other than as a subgenus of Chironomus.
