As some characters of the larvae of Ecnomus distinguish this genus 

 from other genera of Psychomyiinae and Polycentropodinae more sharply 

 than the adults, Lepneva proposed to raise the subfamily Ecnominae Ulm. to 

 the rank of family (Lepneva, 1956:16—26, Figures 1—42). The same was 

 later proposed independently by Marlier (1958:314). Lepneva (ibid.) 

 described the following family characters of the larvae of Ecnomidae, which 

 distinguish it from the Psychomyiidae and Polycentropodidae: l) the 

 chaetotaxy of the frontoclypeus; 2) the form and chaetotaxy of the labrum; 



3) the characteristic form of the mandibles, which are without a penicillus; 



4) the characteristic form of the mental sclerite; 5) the characteristic form 

 of the eulabium, with its relatively large palps; 6) the presence of 

 characteristic, strongly reduced, spoon- shaped setae on the propleuron; 



7) the sclerotized me so- and metanotum; 8) the chaetotaxy of the legs; 

 9) the form and chaetotaxy of the anal legs with the characteristic claw, 

 151 with a ventral comb of spinules. The subfamily diagnosis of the adults 

 is considered as the family diagnosis. 



According to the degree of development of the chaetotaxy of the full-grown 

 larva (it may be nearly absent, little developed, or richly developed) 

 Lepneva divided the suborder Annulipalpia into the 2 superfanillies, 

 Paleochaetoidea and Neochaetoidea (1956:14, 19). The Paleochaetoidea 

 include the lower families of the suborder from the most primitive 

 families: Rhyacophilidae, Glossosomatidae, Hydroptilidae, Philopotamidae, 

 Xiphocentronidae and Psychomyiidae; the Neochaetoidea include the higher 

 families with a relatively rich or richly developed secondary chaetotaxy: 

 Ecnomidae, Polycentropodidae, Arctopsychidae and Hydropsychidae. 



After the aforementioned changes, the classification of the Annulipalpia 

 is as follows: 



I. Annulipalpia Mart. 



A . Paleochaetoidea Lepn. B. Neochaetoidea Lepn. 



1. Rhyacophilidae Steph. 8. Ecnomidae Ulm. 



2. Glossosomatidae Wall. 9. Polycentropodidae Ulm. 



3. Hydroptilidae Steph. 10. Arctopsychidae Mart. 



4. Philopotamidae Steph. 11. Hydropsychidae Curt. 



5. Xiphocentronidae Ross. 



6. Stenopsychidae Mart. 



7. Psychomyiidae Kol. 



The classification of the Integripalpia has also been changed recently. 



Wiggins (1959) described the larvae of Phryganopsyche latipennis 

 Banks, and separated from the Phryganeidae the small family Phrygano — 

 psychidae, which consists of only 2 species, Ph. latipennis Banks, 1906 

 and Ph. cornuta Kimmins, 1950. The adults of this new family do not 

 differ so sharply from the Phryganeidae as the larvae, in which the 

 independence of the family is clearly marked by a number of characters, 

 e. g., form of head and frontoclypeus; uniform light brown color of head and 

 pronotum; presence of a faintly marked submental sclerite; characteristic 

 form of galea and maxillary palps; slightly elongate eulabium, with its large 

 palps; completely sclerotized mesonotum and the absence of a dorsal
