Treatment

Simulium (Gomphostilbia) myanmarense Takaoka, Srisuka & Saeung, in Takaoka et al. 2017b: 40-45 (female, male, pupa, and larva).

Specimens examined.

8 females, 6 males (with their associated pupal exuviae and cocoons), and 20 mature larvae (one mature larva for DNA analysis) (in 80% ethanol), collected from a small stream (width 55 cm, depth 3 cm, bed sandy, moderate flow, pH 7.2, 18.4 °C, partially shaded, elevation 901 m, 19°28'18.3"N, 100°28'00.8"E), at Pha Dang Village, Chiang Kham District, Pha Yao Province, Thailand, 20-III-2018, by W. Srisuka (Coll. No. 75); one female, one male (with their associated pupal exuviae and cocoons), and two mature larvae (in 80% ethanol), collected from a small stream (width 30 cm, depth 5 cm, bed sandy, moderate flow, pH 6.3, 23.6 °C, exposed to the sun, elevation 1,097 m, 18°50'03.7"N, 99°22'32.2"E), at Pa Miang Village, Muang Pan District, Lampang Province, Thailand, 9-VIII-2016, by W. Srisuka (Coll. no. 86).

Diagnosis.

Female: mandible lacking outer teeth. Male: upper-eye facets in 15 (rarely 14) vertical columns and 15 (rarely 16) horizontal rows on each side. Pupa: cocoon with a short anterodorsal projection. Larva: medium-sized postgenal cleft and abdominal segments 1 and 2 each encircled with a grey transverse band (Fig. 25L View Figure 25 ).

Distribution.

Myanmar and Thailand (Phayao and Lampang).

Discussion.

Jomkumsing et al. (2019) suggested the presence in Thailand of S. myanmarense and S. monglaense , both originally described from Myanmar ( Takaoka et al. 2017b), based on the close similarity of the COI gene sequences among females of ' S. asakoae complex’ caught using a human attractant. Our study confirmed the distribution of S. myanmarense in Thailand, based on morphological and molecular evidence.
