The overall declining state of the western taxonomy is clearly documented by the present fate of the extremely high valued and huge unidentified caddisfly material collected in India and deposited in the Canadian National Collection. Due to the general lack of both financial and scientific resources in taxonomy, this huge collection remained almost untouched during the last 70 years after its collection. With a tribute to the collector, Fernand Schmid, the great caddisfly collector and taxonomist we have reconstructed his collecting activities of the five years in India by geolocalization and elaborated about ten percent of his undetermined Hydropsychidae in the Diplectroninae and Hydropsychinae subfamilies. Description of 145 new species from this small fragment of the huge unidentified collection demonstrates a pronounced underestimation of the biodiversity in general, routinely measured by gross phenomics. During this study we have reinstated the species status of seven taxa: Diplectrona kirimaduhela Schmid, 1958, stat. restit., Cheumatopsyche rienga Oláh & Johanson, 2008, stat. restit., Cheumatopsyche amurensis Martynov, 1934, stat. restit., Cheumatopsyche banksi Mosely, 1942, stat. restit., Cheumatopsyche processuata (Martynov, 1927), stat. restit., Potamyia klakahana (Ulmer, 1951), stat. restit., Potamyia proboscida Li & Tian, 1996, stat. restit., and raised the subspecies status to species rank of Diplectrona stigmatica Banks, 1937, stat. nov. Furthermore, we have etablished four new species groups, sixteen new species complexes and described 145 new species as follows: Diplectrona aurovittata new species group: D. hasada new species complex: D. bandara sp. nov., D. borghata sp. nov., D. chiangma sp. nov., D. chingsa sp. nov., D. daotama sp. nov., D. grimona sp. nov., D. jaraina sp. nov., D. khopurna sp. nov., D. khumyara sp. nov., D. kualagomba sp. nov., D. kurlingha sp. nov., D. lyngkota sp. nov., D. mawkhapa sp. nov., D. mirgona sp. nov., D. muktapura sp. nov., D. mynsoa sp. nov., D. nongina sp. nov., D. nongra sp. nov., D. nongronga sp. nov., D. sirkasha sp. nov., D. sironga sp. nov., D. sumatrana sp. nov., D. tairenpokpa sp. nov., D. tungpa sp. nov., D. tamdaophila new species complex: D. aisahka sp. nov., D. beluma sp. nov., D. dhampa sp. nov., D. dhankuta sp. nov., D. huishua sp. nov., D. khasiaca sp. nov., D. khasigupta sp. nov., D. madonga sp. nov., D. meghalaya sp. nov., D. mopaenga sp. nov., D. parala sp. nov., D. rumkhenga sp. nov., D. sitahoana sp. nov., D. sohra sp. nov., D. coalescens species group: D. hongkonga sp. nov., D. kattalaimala sp. nov., D. shimoga sp. nov., D. gombak new species group: D. albofasciata new species complex, D. fasciata new species complex: D. buitenzorga sp. nov., D. panaona sp. nov., D. simalura sp. nov., D. tonkulana sp. nov., D. wailima sp. nov., D. gentinga new species complex: D. gentinga sp. nov., D. gombak new species complex: D. barisana sp. nov., D. merangira sp. nov., D. phanoma sp. nov., D. temengora sp. nov., D. tengaha sp. nov., D. taprobanes new species group: D. abmaka sp. nov., D. kambaita sp. nov., D. kamikarka sp. nov., D. koda sp. nov., D. komadia sp. nov., D. madhya sp. nov., D. satanwada sp. nov., D. sirtranga sp. nov., D. tienmua sp. nov., D. umlanga sp. nov., Cheumatopsyche lepida species group: C. assamha sp. nov., C. fordula sp. nov., C. madpradha sp. nov., C. manimapa sp. nov., C. pondora sp. nov., C. puramukta sp. nov., C. purmapa sp. nov., C. sohkha sp. nov., C. swampa sp. nov., C. dubitans species group: C. mawpya sp. nov., C. excisa species group: C. chuga sp. nov., C. costalis species group: C. dangchura sp. nov., C. kamposka sp. nov., C. lagaironga sp. nov., C. mawjana sp. nov., C. mawprana sp. nov., C. nonga sp. nov., C. nongajra sp. nov., C.oinamla sp. nov., C. salaka sp. nov., C. yunnana sp. nov., C. concava species group: C. haflonga sp. nov., C. kambirona sp. nov., C. khasia sp. nov., C. korosa sp. nov., C. myntanga sp. nov., C. nongrima sp. nov., C. chinensis species group: C. bandarkhala sp. nov., C. delhia sp. nov., C. hanoia sp. nov., C. hotaya sp. nov., C. pega sp. nov., C. quangchua sp. nov., C. tamda sp. nov., C. tongoma sp. nov., C. holzschuhi species group: C. apuma new species complex: C. apuma sp. nov., C. nyukma sp. nov., Potamyia czekanovskii species group: P. flavata new species complex: P. binhoa sp. nov., P. chitwana sp. nov., P. congsa sp. nov., P. moccha sp. nov., P. nikalandugola species complex: P. hasalaka sp. nov., P. tamilnada sp. nov., P. chinensis species group, P. flava species group: P. dinamla sp. nov., P. trenhona species group: P. barata sp. nov., P. jinhongensis new species complex: P. dhauliana sp. nov., P. yunnanica new species complex: P. namha sp. nov., P. namkhana sp. nov., P. topali sp. nov., P. umbaso sp. nov., P. vietnama sp. nov., Hydromanicus hermosus species group: H. flavoguttatus species complex: H. bukit sp.nov., H. mawpyut sp. nov., H. mawshun sp. nov., H. luctuosus species group nom. nov.: H. asor new species complex: H. shilliang sp. nov., H. eleasar new species complex: H. kambaitiensis sp. nov., H. kamengensis sp. nov., H. kashong sp. nov., H. sikkimensis sp. nov., H. tibetensis sp. nov., H. inferior new species complex: H. darban sp. nov., H. hasad sp. nov., H. jakhand sp. nov., H. khalband sp. nov., H. mattiyang sp. nov., H. mynso sp. nov., H. nondeng sp. nov., H. luctuosus species complex: H. fureses sp. nov., H. garhwal sp. nov., H. khopum sp. nov., H. laitlyn sp. nov., H. manilon sp. nov., H. mapum sp. nov., H. pufok sp. nov., H. thangrain sp. nov., H. tharauyang sp. nov., H. tiyang sp. nov., H. tungnath sp. nov., H. umbonatus new species complex: H. kover sp. nov., H. manisir sp. nov., H. ronghongkung sp. nov., H. sirohis sp. nov., H. spatulatus species group: H. rahung sp. nov., H. spatulatus species cluster.
