description: DOLICHOCOLON DALI SP. NOV. (FIG. 19A–C)    Type material: Holotype ♂: China / Jizhaoan, Dali / Yunnan, 4 September 93/ 2310 m, R. Kano [BLKU].   
 Etymology: From the type locality Dali, a noun in apposition.   
 Description: Body length: 10.3 mm.   
 Coloration and pruinescence: Head mainly black, covered with whitish-grey pruinescence. Palpus blackish-brown basally, shading into yellowish-brown distally. Scape and pedicel black. Thorax mainly black; scutellum entirely reddish-yellow; scutum with four presutural dark vittae, lateral vitta subtriangular, distinctly outlined and ending wedge-shaped beside posthumeral seta. Legs black. Tegula and basicosta black to dark brown. Abdominal tergites 3 and 4 with a transverse band of whitish-grey pruinescence (without shifting spots) on anterior 1/3-1/2 (laterally), 1/2-2/3 (medially); tegite 5 pruinose on anterior 2/3. Sides of abdominal tergites 3 and 4 widely red.   
 Head: Compound eye with more or less sparse ommatrichia at least as long as combined diameter of three facets (visible under> 40 ¥ magnification). Arista thickened on basal 2/5–1/2. Second aristomere 7.8 times as long as wide. Thickened part of third aristomere 7.2 times as long as second aristomere. Postpedicel 9.3 times as long as pedicel. Vertex at its narrowest point 1.05 times as wide as compound eye in dorsal view. Lateral vertical seta weak, slightly differentiated from postocular setae; postocular setae relatively long and strongly bent anteriorly. Six to eight frontal setae descending below level of base of arista. Frontal vitta (measured at midlength between fore ocellus and base of antennae) about as wide as fronto-orbital plate (measured at same level). Frontoorbital plate with one row of medioclinate setae lateral to row of frontal setae. Gena in profile 0.27

times as high as compound eye. Prementum about 1.0–1.5 times as long as wide.  
 Abdomen: Syntergite 1 + 2 without median marginal setae. Tergite 3 with one pair of median marginal setae 0.9 times as long as corresponding tergite. Tergite 4 with a row of 12 marginal setae shorter than corresponding tergite. Tergite 5 with a row of marginal and discal setae.   
 Male terminalia: The male terminalia are very similar to those of D. paravicinum sp. nov. but in D. dali the basal 2/3 of cerci are more prominent (Fig. 19A, C), and the posterodistal 1/3 of surstylus is not strongly concave and not pointed apically as in D. paravicinum (Fig. 19A, B). Furthermore, posterodorsal surface of surstylus in D. dali lacks microtrichia (Fig. 19B).   
 Hosts: Unknown.   
 Distribution: Oriental: China (Yunnan).
