CA04E109FFE1FFCF0994548451AEFB41.taxon	diagnosis	Diagnosis. The new species can be recognized by following combination of characters: final part of Scabsent, R 5 straight except arched base, R 5 and M 1 divergent; gonocoxite elongated, broad basally and narrowed to the apex, outer gonostylus narrowed, inner gonostylusin the shape of broad lobe, longer than outer gonostylus. The new species is most similar to another fossil species from Dominican amber, B. brodzinskii Krzeminski, 1996, but differs from the latter by the absence of final part of Sc (present in related species), the origin of Rs obliquely arcuated (the origin of Rs right-angled in shape in related species), the petiole of cell m 1 subequal in length to M 2 (the petiole of cell m 1 distinctly shorter than M 2 in related species), the petiole of cell m 1 distinctly longer than the cross vein m-m (the petiole of cell m 1 subequal in length to cross vein m-m in related species), and the discal cell 2.2 times as long as the width (the discal cell 1.7 times as long as the width in related species). Material examined. Holotype, male, No. AQNU-DIP- 2019004, Miocene (18 – 20 Ma), La Toca mine, Santiago Province, the Dominica Republic. Description. Measurement (n = 1). Body length 8.36 mm (excluding antenna), wing 10.80 mm, antenna 5.27 mm. Head. Head brown with black setae (Fig. 1 A). Nasus distinct with several black setae on tip. Antenna entirely black, 11 - segmented, scape and pedicel cylindrical, slightly expanded apically, first flagellomere subequal in length to scape and pedicel together, remaining flagellomeres progressively shorter and thinner except last segment which is same length to second flagellomere, each flagellomere with numerous black verticils, longest verticil distinctly shorter than its corresponding flagellomere (Fig. 2 A). Palpus wholly black, longer than antenna, last segment almost same length to basal three segments together (Fig. 2 B). Thorax. Thorax brown (Fig. 1 A). Legs wholly brown (Fig. 1 A). Fore leg with femur 8.02 mm, tibia 8.61 mm, tarsi 12.90 mm; middle leg with femur 9.91 mm, tibia 9.20 mm; hind leg with femur 10.50 mm. Wing brown with dark brown venation, narrowed and elongated, transparent, with an elliptic stigma not reaching anterior margin of wing (Fig. 2 B). Venation: Sc long, ending distinctly beyond mid-point of wing, sc-r reaching at same level of branch of Rs, final part of Sc absent (Figs 1 C, 2 C); Rs distinctly arcuate at base, slightly longer than R 2 + 3 + 4; R 1 and R 3 short; R 4 elongated, apical one third curved; R 5 elongated, straight except base arched, R 5 and M 1 divergent; cell m 1 present, slightly longer than its petiole; M 2 as long as petiole of cell m 1; r-m absent; discal cell elongated, approximately 2.2 times as long as width; m-m distinctly shorter than petiole of cell m 1; m-cu reaching discal cell at distal one fourth; CuA and CuP relatively straight with apex slightly bent, A 1 straight. Halter with stem yellow, knob black (Figs 1 B, 2 C). Abdomen. Abdomen brown with hypopygium black (Figs 1 A, 1 D). Tergite nine small, straight at hind margin (Fig. 2 D). Gonocoxite elongated, broad basally and narrowed to apex, densely covered with long setae (Figs 2 D – E). Outer gonostylus being narrowed rod, inner gonostylus longer than outer, being broad lobe (Figs 2 D – E). Etymology. This specific name is dedicated to Mrs. Chen Huamei for her contribution of this Dominican amber.	en	Men, Qiulei, Hu, Zhengkun (2020): A new species of Brachypremna (Diptera: Tipulidae) from Dominican amber, with a key of the genus to all fossil species.
