Material.
Holotype: Philippines • 1 male nymph; Negros Oriental, Valencia, Casaroro River downstream; 09°18'N, 123°14'E; c. 150 m a.s.l.; 1 Sep. 2019; leg. Garces; GenBank: MN853779; PNM: EPH 356/ PNM 13683 in ethanol. Paratypes: Philippines • 2 nymphs; same collection data as holotype; GenBank: MN853780, MN853785; AdMU: EPH 155 in ethanol, EPH 357 on slide • 3 nymphs; Negros Oriental, Valencia, Apolong, Casaroro River upstream; 09°17'N, 123°13'E; 470 m a.s.l.; 1 Sep. 2019; leg. Garces; GenBank: MN853783, MN853782, MN853781; AdMU: EPH 160 in ethanol, ZSM: EPH 158 in ethanol, EPH 157 on slide • 1 nymph; Negros Oriental, Valencia, Malaunay; 09°18'22"N, 123°10'04"E; c. 470 m a.s.l.; 1 Sep. 2019; GenBank: MN853779; AdMU: EPH 150 on slide.
Diagnosis.
Dudgeodes bauernfeindi sp. nov. can be distinguished from other Oriental Dudgeodes by the combination of the following characters: (1) antenna length subequal to head width, (2) dorsal part of male eyes brown, (3) two prothorax tubercles, (4) simple mesothorax marginal setae, (5) two tarsal claw subapical teeth, (6) narrow teeth on median and lateral area of posterior margin tergite VI, (7) tergite VII posterior margin teeth present on the entire length, (8) longest setae on cerci basal segments more than half of the corresponding segment (9) longest setae on cerci distal segments half to the corresponding segments, and (10) presence of brownish band every four segments of the cerci. Dudgeodes bauernfeindi sp. nov. can be differentiated from D. luntian sp. nov. found also in Negros island by the length of antenna relative to head width, color of dorsal part of male eyes, mesothorax marginal setae and tarsal claw subapical teeth.
Description.
Mature nymph. Body length ♂ 5.0-5.2 mm; cerci 0.9-1.0 times body length.
Head: Antennae 0.9-1.0 times head width, flagellum with 16-18 segments. Dorsal part of male eyes brown (Fig. 2A View Figure 2 ). Labrum wide, ca. 2.3-2.5 times wider than long, concave in central part of anterior margin. Labial palp segment III elongated, 2.8-3.0 times as long as wide at base.
Thorax: Pronotum (Fig. 2B View Figure 2 ) with four flat tubercles. Mesonotum (Fig. 2B View Figure 2 ) without tubercle; outer margin with regular row of simple setae.
Legs: Forefemur dilated, ca. 1.5-1.6 times longer than wide; transverse row of long and bluntly pointed setae (Fig. 14A View Figure 14 ) across dorsal face; dorsal surface sparsely covered with long thin simple setae. Fore tarsal claw hooked, bearing four blunt teeth medially and two teeth subapically. Middle and hind femora ca. 2 times longer than wide. Middle and hind tarsal claw hooked, bearing four to five blunt teeth medially and two teeth subapically.
Abdomen: Tergite with median tubercles (Fig. 2B View Figure 2 ) slightly developed on segments I and II, moderately developed on segment III and IX-X, well developed on IV-IX. Posterolateral projections (Fig. 2C View Figure 2 ) slightly developed on segments II-IV, moderately developed on V-IX.
Tergites IV-X (Figs 15E View Figure 15 , 16E View Figure 16 ) surface covered with short thin setae, thick setae with feathered apex and apically rounded feathered thick setae; posterior margin with long pointed thick setae, elongated forked thick setae and long setae with feathered apex. Narrow slender teeth present on posterior margin median area of tergites I-V, posterior margin median and lateral areas of tergite VI (Fig. 15E View Figure 15 ), and across entire posterior margin of tergites VII-X (Fig. 16E View Figure 16 ).
Cerci with apically blunt thick setae every segment; longest setae on basal segments more than half of corresponding segment; longest setae on distal segments half of corresponding segments. Brownish band present every four segments (Fig. 2A View Figure 2 ).
Etymology.
The species is named after Dr. Ernst Bauernfeind (Vienna), one of the mentors of the first author, for his kindness and outstanding contribution to mayfly taxonomy.
Distribution and biology.
Dudgeodes bauernfeindi sp. nov. is so far only known from Negros island, Philippines. All material was collected at altitudes of 150-500 m a.s.l. mostly surrounded by secondary vegetation, rarely secondary forest, with few houses in some distance from the river bed.
