Capnia

Murányi, Dávid, Li, Weihai & Yang, Ding, 2015, A new genus and species of winter stoneflies (Plecoptera: Capniidae) from Southwest China, with a commented checklist of the family in the Oriental Realm, Zootaxa 4059 (2), pp. 371-382 : 379-380

Capnia s.l. pedestris species group sensu Zwick & Sivec 1980

This group was erected for eleven Asian species ( Alouf 1992, Murányi et al. 2014, Zhiltzova 2003, Zwick & Sivec 1980). Here we exclude two species known from the Caucasus, Anatolia and the Levant, C. s.l. arensi Zhiltzova, 1964 and C. s.l. bicornata Alouf, 1992 , because of the marked differences in epiproctal structures noted by Murányi et al. (2014). The rest of the species are known from the central high mountains of Asia. Seven species occur in the Tien Shan and Pamir ranges of the Palaearctic ( Kazakhstan, Kyrgyzstan, Tajikistan and Uzbekistan); two of these are also known from the Oriental Realm. Four further species, among one that is here assigned to the group, occur exclusively in the Oriental Realm:

Capnia s.l. bifida Jewett, 1960

Jewett 1960: description of male and female, holotype, allotype and paratypes from Himachal Pradesh State of

India: Lahaul and Spiti District.

Jewett 1970: further records from the same District of Himachal Pradesh. Known only from a small area of the Western Himalayas.

Capnia s.l. sp., aff. bimaculata Zhiltzova, 1969

Zwick & Sivec 1980: description of male, female and larva, from Afghanistan: Hindukush ranges

(Badakhshan Province); comparision with unspecified Palaearctic specimens of C. s.l. bimaculata . The nominal C. s.l. bimaculata is known from nearby areas of the Palaearctic: Pamir and Tien Shan ranges ( Kyrgyzstan, Tajikistan and Uzbekistan). The Oriental Realm population from the Hindukush was reported from the same area (localities less than 10 km apart) as C. s.l. noshaqensis Kawai, 1966 , and the two are probably conspecific.

Capnia s.l. femina Kawai, 1968

Kawai 1968: description of female and larva, holotype and paratypes from Nepal: Sagarmantha Zone. Hitherto known only from the types collected from the slope of Mt. Everest.

Capnia s.l. longicauda Zhiltzova, 1969

Capnia sp.: Šámal 1935: data of females from Jammu and Kashmir State of India: Karakoram ranges (Siachen Region); whereabouts of the localities Skiang Poche and Chimsin-Jilgha Valley, from where he reported it as a further Capnia female and an additonal one as Nephelopteryx spec.? are unknown.

Zwick & Sivec 1980: complementary description of male and female, resolve the identity of specimens reported by Šámal (1935) (as Capnia spec. and Nephelopteryx spec.?) are C. s.l. longicauda , and first records from Nepal: Dhawalagiri and Karnali zones.

Sivec 1982: first report from Nepal: Mechi zone.

Besides E. stigmatica transversa , this species has the widest distribution among the Capniidae known from the

Oriental Realm. Reported from the eastern Himalayas and the Karakoram, and originally was described from the

Palaearctic: Tien Shan Ranges ( Kazakhstan, Kyrgyzstan).

Capnia s.l. noshaqensis Kawai, 1966

Kawai 1966: description of female, holotype and paratypes from Pakistan: Hindukush ranges (Khyber Pakhtunkhwa province).

The species was not previously assigned to the pedestris group, but the female subgenital plate suggests this classification. Hitherto known only from the female types. As mentioned above, probably conspecific with C. s.l. sp., aff. bimaculata sensu Zwick & Sivec 1980.

Capnia s.l. pedestris Kimmins, 1946

Kimmins 1946: description of male, holotype from Tibet Autonomous Region of China: Shigatse prefecture; notes on the probable larva.

Aubert 1959: description of female and larva from Pakistan: Himalayan ranges (Khyber Pakhtunkhwa Province).

Kawai 1963: complementary description of larva from Pakistan: Karakoram ranges (Gilgit-Baltistan administrative territory) and Jammu and Kashmir State of India: Himalayan ranges (Ladakh region).

Allocapniella pedestris ( Kimmins, 1946) : Kawai 1966: comb. n., complementary description of male and larva

from Pakistan: Hindukush ranges (Khyber Pakhtunkhwa province).

Zwick & Sivec 1980: complementary description of male, material not specified.

Kawai (1966) transferred this species to Allocapniella Kawai, 1955 on the basis of thoracal sclerites. This combination was already ignored (e.g. Zhiltzova 1974, Zwick & Sivec 1980) and when Allocapniella proved to be junior synonym of Apteroperla Matsumura, 1931 this species was not mentioned among the new combinations ( Shimizu 1997). Here we support its exclusion from Apteroperla , on the basis of having rather different genitalia characters, e.g. lack of eversible crest and having elongated fusion plate (compare Figs. 13–14 , 27 in Murányi et al. (2014) with Figs. 48.G–H in Kawai (1967)). It has a rather wide distribution: in addition to Central (Eastern) Himalayas, Karakoram and Hindukush, it is reported also from the Palaearctis: Pamir ranges ( Tajikistan).
