Material.

Holotype: Philippines • 1 mature female nymph; Luzon, Laguna, Majayjay, Bukal, Mimpis River; 14°06'60"N, 121°27'54"E; 425 m a.s.l.; 26 June 2018; BIO-PHIL exped.; GenBank: MN853843; PNM: EPH 345/ PNM 13682 in ethanol. Paratypes: Philippines • 6 nymphs; same collection data as holotype; GenBank: MN853835, MN853837, MN853840, MN853841, MN853842, MN853836; AdMU: EPH 180 and EPH 182 on slides, EPH 342, EPH 343, EPH 344 in ethanol, ZSM: EPH 181 on slide • 2 nymphs; Luzon, Laguna, Majayjay, Taytay River; 14°06'42"N, 121°30'19"E; 510 m a.s.l.; 27 June 2018; BIO-PHIL exped.; GenBank: MN853838, MN853839; AdMU: EPH 188 on slide, ZSM: EPH 189 on slide.

Diagnosis.

Dudgeodes vonrinteleni 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 blackish, (3) six prothorax tubercles, (4) two mesothorax tubercles, (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 less than half to the corresponding segments, and (10) absence of brownish band on the cerci. Dudgeodes vonrinteleni sp. nov. can be separated from other Dudgeodes from Luzon island ( D. pescadori , D. luntian sp. nov., D. freitagi sp. nov.) by the number of tarsal claw subapical teeth, longest setae on cerci distal segments less than half to the corresponding segments and absence of brownish band on the cerci. Dudgeodes vonrinteleni sp. nov. resembles D. ulmeri based on thorax tubercles, tarsal claw and size but can be separated by color of dorsal part of male eyes, apex of forefemur transverse setae, and tergites VI and VII posterior margin teeth presence.

Description.

Mature nymph. Body length ♂ 5.1-5.5 mm, ♀ 6.3-6.5 mm; cerci 1.0-1.3 times body length.

Head: Antennae 0.9-1.0 times head width, flagellum with 16-18 segments. Dorsal part of male eyes blackish (Fig. 7A View Figure 7 ). Labrum wide, ca. 2.3-2.5 times wider than long, slightly concave in central part of anterior margin. Labial palp segment III elongated, 3.2-3.6 times as long as wide at base.

Thorax: Pronotum (Fig. 7B View Figure 7 ) with six tubercles, four round and two flat. Mesonotum (Fig. 7B View Figure 7 ) with two flat tubercles; outer margin with regular row of forked thick setae.

Legs: Forefemur dilated, ca. 1.4-1.6 times longer than wide; transverse row of long and apically combed setae across dorsal face; dorsal surface uniformly covered with hair-like setae; dorsal surface, outer and inner margin sparsely with short thick setae. Fore tibia outer margin with middle-sized thin setae; inner margin with few apically pointed thick setae; dorsal surface with regular row of long thick setae. Fore tarsal claw hooked, bearing five 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 blunt teeth medially and two teeth subapically.

Abdomen: Tergite with median tubercles (Fig. 7B View Figure 7 ) moderately developed on segments I and II, well developed on segments III to X. No posterolateral projections (Fig. 7C View Figure 7 ) on segments II and III, slightly developed on segments IV and V, moderately developed on segments VI-IX.

Tergites IV-VI (Fig. 15C View Figure 15 ) surface covered with short thin setae, thick setae with feathered apex and apically rounded feathered thick setae; posterior margin with forked robust thick setae and thick setae with feathered apex and apically rounded feathered thick setae. Tergites VII-X (Fig. 16C 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 present on posterior margin of tergites I-V diminishing distally, posterior margin median and lateral area of tergite VI (Fig. 15C View Figure 15 ), and across entire posterior margin of tergites VII-X (Fig. 16C 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 less than half of corresponding segments. Brownish band absent (Fig. 7A View Figure 7 ).

Etymology.

The species is named after BIO-PHIL project head Dr. Thomas von Rintelen (Berlin) for his continuous support in biodiversity research in Southeast Asia and for the preliminary training of the first author in DNA Taxonomy.

Distribution and biology.

Dudgeodes vonrinteleni sp. nov. is so far only known from Luzon island. All material was collected at altitudes of 400-500 m a.s.l. surrounded by secondary forest (Fig. 17B View Figure 17 ).
