( Fig. 3 )

Tagenostola turkestanica albovillosa Koch, 1940: 735 (original description).

Type locality. ‘Vorderindien’.

Type material. Holotype and paratype in NHMB, not examined.

Additional material examined. LAOS: SEKONG PROVINCE: ca. 12 km S Sekong, Tad Faek waterfalls (at light), 15°14.7′N 106°45.1′E, 118 m, 8.+ 12.v.2010, leg. Jiří Hájek (1 spec. NMPC) . MYANMAR: YANGON REGION: Pégu, 60 km NNE Yangon, 17°16′N 96°28′E (lux), 22.xi.2003, leg. M.Hornburg (1 spec. RFCL) ; MANDALAY REGION: Bagan env., 21°09′N 94°53′E, alt. 80 m, 10.–14.+ 22–24.x.2014, leg. R.Fouquè (2 ♀♀ RFCL). TENASSERIM REGION: Mekane, 90 km E of Moulmein, 200 m, 2.–8.xi.1984, leg. Malaise (2 spec. NHRS). NEPAL: BAGMATI ZONE: Halambu Distr. , Gosaigonda [= Gosaikunda Lake] 1300 m, 1.–16.v.1989, leg. Pashang (1 spec. SBPC) ; NARAYANI ZONE: Chitwan, Narayanghat 170 m, 12.xi.1993, leg. Moor et al. (1 spec. NHMW). VIETNAM: QUANG BINH PROVINCE: 1 km N of Cha Lo, 400m, Vietnam-Laos border area , 17°41′22″N 105°45′45″E, 11.–24.iv.2010, leg. L. Dembický (1 spec. NHMB).

Diagnosis. This species differs from T. turkestanica in long and thin legs, anterior tibiae length/ width ratio 8.00. Head ratio of width on eyes/cervix 2.25. Posterior half of elytra narrowed almost directly to apex.

Distribution. Bhutan ( KASZAB 1975), Northern India ( KOCH 1940, ARNDT & FERRER 1997), Laos (present paper), Myanmar ( MEDVEDEV 1994, present paper), Nepal ( ARNDT & FERRER 1997, present paper), Vietnam (present paper). New species records and the first record of the genus Tagenostola for Laos and Vietnam.

Remarks. The genus Tagenostola in Asia includes the following species: T. pilosa (Motschulsky, 1839) known from eastern Transcaucasia to northern Caucasian Area, T. seriepillosa mulleri ( Reitter, 1886) known from Saudi Arabia, Egypt and Sudan, T. turkestanica turkestanica ( Reitter, 1886) known from southern Kazakhstan, Middle Asia and Afghanistan, and T. turkestanica albovillosa Koch, 1940 known from India, Nepal, Bhutan and Myanmar. I was not able to study the type material, but the genus should be revised. KOCH (1940) described new subspecies of T. turkestanica mainly based on different color of setae, narrower head, and tempora directly narrowed to cervix. MEDVEDEV (2008) used the color of setae and the length/width ratio of posterior femur as differential characters in his key. The study of non- - type material of both subspecies revealed that the main difference is the different length of legs, particularly the length of tibiae which are markedly longer in T. tukestanica albovillosa . Based on the above-mentioned characters and on the different distribution, T. turkestanica albovillosa is herewith raised to species level.

The species seems to be attracted to the lights as the two specimens collected by the author in Myanmar were found after nightfall on the pedestal of a light banner to the temple. Similarly the specimen from Laos was collected during light trapping.
