Material.
Holotype: Philippines • 1 mature female nymph; Leyte, Ormoc, Dolores, Lake Danao outflow creek; 11°04'37"N, 124°41'46"E; 650 m a.s.l.; 26 Sep. 2019; leg. Garces; GenBank: MN853829; PNM: EPH 194/ PNM 13684 in ethanol. Paratypes: Philippines • 1 nymph; same collection data as holotype; GenBank: MN853828; AdMU: EPH 193 on slide • 5 nymphs; Leyte, Ormoc, Dolores, Lake Danao tributary; 11°03'55"N, 124°42'17"E; 650m asl.; 26 Sep. 2019; leg. Garces; GenBank: MN853830, MN853832, MN853834, MN853831, MN853833; AdMU: EPH 331, EPH 333, EPH 335 on slides, EPH 332 in ethanol, ZSM: EPH 334 in ethanol.
Diagnosis.
Dudgeodes tabang sp. nov. can be distinguished from other Oriental Dudgeodes by the combination of the following characters: (1) antenna length longer than head width, (2) dorsal part of male eyes brown, (3) four prothorax tubercles, (4) pointed forefemur transverse setae apex, (5) one tarsal claw subapical teeth, (6) no teeth on tergite VI posterior margin, (7) narrow teeth on lateral area of posterior margin tergite VII, (8) longest setae on cerci basal segments half of the corresponding segment (9) longest setae on cerci distal segments greater than the corresponding segments, and (10) presence of brownish band every four segments of the cerci. Dudgeodes tabang sp. nov. resembles D. hutanis based on size, antenna length and thorax tubercles but can be separated by color of dorsal part of male eyes, number of subapical tarsal claw teeth and presence of brownish band on cerci.
Description.
Mature nymph. Body length ♂ 4.6-5.0 mm; cerci 0.8-0.9 times body length.
Head: Antennae 1.0-1.2 times head width, flagellum with 16-18 segments. Dorsal part of male eyes brown (Fig. 6A View Figure 6 ). Labrum wide, ca. 2.4-2.6 times wider than long, slightly concave in central part of anterior margin. Labial palp segment III elongated, 3.2-3.4 times as long as wide at base.
Thorax: Pronotum (Fig. 6B View Figure 6 ) with four round tubercles. Mesonotum (Fig. 6B View Figure 6 ) without tubercle; outer margin with regular row of forked thick setae.
Legs: Forefemur dilated, ca. 1.4-1.6 times longer than wide; transverse row of pointed thick setae (Fig. 14C View Figure 14 ) across dorsal face; dorsal surface, outer and inner margin sparsely with short thick setae. Fore tarsal claw hooked, bearing four blunt teeth medially and one tooth subapically. Middle and hind femora ca. 2 times longer than wide. Middle and hind tarsal claw hooked, bearing four blunt teeth medially and one tooth subapically.
Abdomen: Tergite with median tubercles (Fig. 6B View Figure 6 ) moderately developed on segments I and II, well developed on segments III to X. No posterolateral projections (Fig. 6C View Figure 6 ) on segments II and III, slightly developed on segments IV and V, moderately developed on segments VI-IX.
Tergites IV-VI (Fig. 15F View Figure 15 ) surface covered with short thin setae, thick setae with feathered apex and apically rounded feathered thick setae; posterior margin with long pointed thick setae, thick setae with feathered apex and apically rounded feathered thick setae. Tergites VII-X (Fig. 16F View Figure 16 ) surface and posterior margin with short thin setae, thick setae with feathered apex and apically rounded feathered thick setae. Narrow slender teeth absent on posterior margin of tergites I-VI (Fig. 15F View Figure 15 ), present in posterior margin lateral area of tergite VII (Fig. 16F View Figure 16 ), and present across entire posterior margin of tergites VIII-X.
Cerci with apically blunt thick setae every segment; longest setae on basal segments half of corresponding segment; longest setae on distal segments more than half of corresponding segments. Brownish band present every four segments (Fig. 6A View Figure 6 ).
Etymology.
The species is named after the words tab-ang and tabang which mean freshwater and help in Cebuano language, respectively. This species alludes to a cry for help from science, private, and government sectors to converge towards a common freshwater conservation goal of enhancing species richness and ecosystem health even, and especially, in human-dominated inland landscapes.
Distribution and biology.
Dudgeodes tabang sp. nov. is so far only known from Leyte island, Philippines. All material was collected at altitudes of 500-600 m a.s.l. surrounded by secondary vegetation, rarely secondary forest.
