Biological notes. The pupae and larvae of S. (S.) daoense sp. nov. were collected from grass leaves and roots trailing in the current. Associated species were S. (G.) hongthaii , S. (S.) sapaense sp. nov. and S. (S.) phuluense sp. nov.

Distribution. Vietnam (Lao Cai).

Etymology. The species name daoense refers to the land in which the Dao tribe lives.

Remarks. Simulium (S.) daoense sp. nov. is assigned to the S. multistriatum species-group of the subgenus Simulium , redefined by Takaoka and Davies (1996), based on the female scutum with five longitudinal vittae, female ovipositor valves thin and unpigmented along inner margins ( Fig. 48 View FIGURE 48 D), male style with elongate basal protuberance ( Fig. 49 View FIGURE 49 E), pupal gill with eight filaments ( Fig. 50 View FIGURE 50 G), and cocoon with an anterolateral window on each side ( Fig. 50 View FIGURE 50 J, K).

This new species is characterized by the bare basal portion of the radial vein of the female wing, ellipsoidal male sensory vesicle ( Fig. 49 View FIGURE 49 A), unbranched mediolateral and ventrolateral trichomes of the pupal thorax ( Fig. 50 View FIGURE 50 E, F), pupal gill filaments divergent at an angle of about 90 degrees when viewed laterally ( Fig. 50 View FIGURE 50 G), and cocoon with an enlarged window on each side ( Fig. 50 View FIGURE 50 J, K).

This new species is similar in the arrangement of the pupal gill filaments to the following species but is distinguished from them by the following characters (those of other species in parentheses); from S. (S.) xialongtanense Chen, Luo & Yang described from Hubei, China ( Chen et al. 2006) by the male upper-eye facets in 18 vertical columns and in 18 or 19 horizontal rows (in 12 vertical columns and 12 horizontal rows), male style with a basal protuberance without minute spines ( Fig. 49 View FIGURE 49 E) (with spines), and spine-combs on pupal abdominal segment 8 (spine-combs on pupal abdominal segments 7 and 8); from S. (S.) bifengxiaense Huang, Zhang & Chen described from Sichuan, China ( Huang et al. 2013) by the female cibarium without tubercles ( Fig. 48 View FIGURE 48 B) (with about 15 tubercles) and male ventral plate with its posterior margin nearly straight when viewed ventrally ( Fig. 49 View FIGURE 49 C) (posterior margin round); from S. (S.) chongquingense Zhu & Wang from Chong Quing, China ( Zhu and Wang 1995) by yellow hairs on the male scutum (dark hairs); from S. (S.) uncum Zhang & Chen from Guizhou, China ( Zhang and Chen 2001) by the male upper-eye facets in 18 vertical columns and in 18 or 19 horizontal rows (in 16 vertical columns and 13 horizontal rows); from S. (S.) chainarongi Kuvangkadilok & Takaoka from Thailand ( Takaoka and Kuvangkadilok 1999) by the male ventral plate with its posterior margin nearly straight when viewed ventrally ( Fig. 49 View FIGURE 49 C) (posterior margin round) and wall-pocket-shaped cocoon ( Fig. 50 View FIGURE 50 J, K) (shoeshaped cocoon); from S. (S.) demolaense Takaoka & Somboon from Bhutan ( Takaoka and Somboon 2008) by the ellipsoidal male sensory vesicle ( Fig. 49 View FIGURE 49 A) (globular), male hind basitarsus with its greatest width at apical onethird ( Fig. 49 View FIGURE 49 B) (greatest width at the middle) and ventral plate covered with many minute setae ( Fig. 49 View FIGURE 49 C) (a few setae); from S. (S.) hirtinervis Edwards from Peninsular Malaysia ( Takaoka and Davies 1995) by the bare basal portion of the female radial vein (haired); from S. (S.) malayense Takaoka and Davies from Peninsular Malaysia ( Takaoka and Davies 1995) by the pupal head densely covered with tubercles (bare) and cocoon with a large anterolateral window on each side ( Fig. 50 View FIGURE 50 J, K) (without such a window); and from S. (S.) sakishimaense Takaoka from the Ryukyu Islands, Japan ( Takaoka 1977) by the male upper-eye facets in 18 or 19 horizontal rows (in 15 horizontal rows) and spine-combs on pupal abdominal segment 8 (spine-combs on pupal abdominal segments 7 and 8).

Four related Indian species, S. (S.) barraudi Puri , S. (S.) dentatum Puri , S. (S.) digitatum Puri , and S. (S.) novolineatum Puri (Puri 1932b, 1933a ), differ from this new species by the shape and hairlessness of the male ventral plates.

The remaining species of the S. multistriatum species-group have the pupal gill filaments much diverged at an angle of about 120 degrees when viewed laterally, or shoe-shaped cocoons, or enlarged basal fenestra at the base of the pupal gill, all differing from those of this new species.
