Makarchenko, Eugenyi A., Semenchenko, Alexander A., Krasheninnikov, Andrey B., Yanygina, Lubov V. & Yavorskaya, Nadezhda M., 2024, Review of archaic nymphomyiids (Diptera, Nymphomyiidae) of the Russian Far East and bordering territories, with describing of new taxa and DNA barcoding of known species, Zootaxa 5448 (2), pp. 183-211 : 192

Nymphomyia orientalis makcha Makarchenko et Semenchenko , subsp. nov.

( Figs. 12, 14 )

Type material. Holotype: adult male, RUSSIA: Amur Region, Zeiskyi District, environs of Zeya Town, Makcha River , 53.685022 N 127.064882 E, 29.VI.2016, leg. N. Yavorskaya and E. Makarchenko. Paratypes: 18 adult males, 21 females, the same data as holotype, 29.VI.2016, leg. N. Yavorskaya and E. Makarchenko.

Derivatio nominis. The subspecies is named after the Makcha River, from which the type material was collected. The name is a noun in apposition.

Ecology and biology. Larvae and pupae of N. orientalis makcha subsp. nov. were collected in the Makcha River ( Fig. 47 ) on the gravel-pebble soil of a riffle, at a depth of 10–20 cm, at a water temperature of 12.9 ºС and pH 7.5–7.7. Numbers of larvae reached 48 ind./m 2 in July 1, 2016, and 144 ind./m 2 for pupae. Along with pupae, wingless adults were found in the samples, which confirms the emergence of nymphomyids already in June when the water in the river warms up to 12 ºС. Adult swarming on this river was observed on June 29, 2016 ( Yavorskaya & Makarchenko 2015).

Distribution. N. orientalis makcha subsp. nov. is known from type locality in Makcha River of Zeya River basin only ( Fig. 2 ).
