03F6937CFFF0FFB8CBE50AB0162EFE02.taxon	description	Description. Body and appendages yellowish. Forewings greyish brown and hind wings hyaline. Length of each forewing 4 mm. Male genitalia (Figures 1 A – 1 D). Segment IX kidney-bean-like with pointed ventroposterior edge in lateral view (Fig. 1 B); subrectangular with 1 / 3 of its length having pair of U-shaped incisions posteriorly in ventral view (Fig. 1 C). Intermediate appendages each triangular with flask-bottle-like incision posteromesally in dorsal view (Fig. 1 A), beak-like in lateral view (Fig. 1 B). In dorsal view, dorsolateral processes of preanal appendages curved inward basally and curved outward and needle-like subapically, in lateral view (Fig. 1 B) needle-like, first turned downward and then abruptly turned caudad, pointed apically; mesolateral processes curved outward, thumb-like in dorsal view (Fig. 1 A), long, curved downward, beak-like with setae in lateral view (Fig. 1 B); mesoventral process of each preanal appendage beak-like with moderate protrusion posteromesally in lateral view (Fig. 1 B). In lateral view, inferior appendages straight, relatively broad, each divided into dorsal branch and ventral branch; dorsal branch very small, triangular with numerous bristles posteriorly, pointed dorsally; ventral branch short, pointed posteroventrally, with numerous setae (Fig. 1 B). In ventral view, inferior appendages long oval; ventral branch of each inferior appendage parallel-sided with numerous long setae along posteromesal edge; dorsal branch cylindrical, bent inward, beak-like posteriorly (Fig. 1 C). Phallus plough-handle-like with two long tube-like processes crossing subapically (Fig. 1 D).	en	Suwannarat, Nannaphat, Malicky, Hans, Laudee, Pongsak (2020): Four new species of caddisflies (Trichoptera: Polycentropodidae, Psychomyiidae Hydropsychidae, Odontoceridae) from Khao Nan and Tai Rom Yen National Parks, southern Thailand.

03F6937CFFF0FFB8CBE50AB0162EFE02.taxon	diagnosis	Diagnosis. The new species is very similar to P. akrisios Malicky 1997 with which it shares the unusual shape of the phallus; which may raise the question of the proper generic position. We leave both species in Polyplectropus until a new revision of Polycentropodidae is available. The characters that can differentiate the new species from P. akrisios are the shapes of the apical ends of the inferior appendages and the sharp intermediate appendages. Polyplectropus hofmaierae n. sp. has the posterior edge of each inferior appendage running diagonally to the posteroventral point and is densely covered by short, stiff bristles on that edge (Fig. 1 E). In P. akrisios the posterior end of each inferior appendage is rounded with a prominent dorsal point and is covered with only sparse fine hairs. The intermediate appendages of the new species are beak-like in lateral view (Fig. 1 B) but rounded in P. akrisios.	en	Suwannarat, Nannaphat, Malicky, Hans, Laudee, Pongsak (2020): Four new species of caddisflies (Trichoptera: Polycentropodidae, Psychomyiidae Hydropsychidae, Odontoceridae) from Khao Nan and Tai Rom Yen National Parks, southern Thailand.

03F6937CFFF3FFB9CBE5084B1729FD5E.taxon	diagnosis	Diagnosis. Male genitalia structures of this species are very similar to those of its congeners, which are constructed in the same pattern, but differences are seen in the details and form of the phallus and can easily be seen in by comparison with figures of the phalli of other species (Figs. 2 D – 2 N). The new species is similar to E. akrichalakchmi Schmid 1972 from the state of Manipur, in that the distal part of the phallus is shorter than in most species (Fig. 2 L), and the inner edge of each inferior appendage has a sub-basal hump. However, in E. chinachotiae n. sp., the basal two-thirds of the phallus is slender and sinuate; the distal part has a dorsal hump with a very slender spine on its caudal edge and is bent downward and dilated more than for E. akrichalakchmi.	en	Suwannarat, Nannaphat, Malicky, Hans, Laudee, Pongsak (2020): Four new species of caddisflies (Trichoptera: Polycentropodidae, Psychomyiidae Hydropsychidae, Odontoceridae) from Khao Nan and Tai Rom Yen National Parks, southern Thailand.

In dorsal view (Fig. 4 A), segment IX somewhat triangular and with shallow U-shaped excision anteriorly; in lateral view (Fig. 4 B), segment IX hexagonal, lateral margins slightly concave anterodorsally and posterodorsally; segment IX divided by lateral horizontal grooves into two parts, dorsal part slightly taller than ventral part. Preanal appendages semicircular along posterior edges of segment IX in dorsal view (Fig. 4 A); in lateral view, preanal appendages transversely crescent-shaped and with setae; segment X small, tubular, rounded posteriorly with setae in dorsal view (Fig. 4 A); in lateral view, segment X scale-like with setae present mostly parallel with posterior edge of preanal appendages (Fig. 4 B). Inferior appendages each with coxopodite straight, long and cylindrical with two subapical lobes nearly identical in shape and size in lateral view, separated by harpago (Fig. 4 B); harpago slender, setose, inserted between subapical lobes (Fig. 4 B) in lateral view.

The genitalia of the new species are similar to those of L. chantaramongkolae found in northern Thailand (Malicky 1989) and in southern China (Yang et al 2017). They can be distinguished by characteristics of the dorsal view of segment IX. In L. chantaramongkolae, segment IX is rectangular with relatively small, concave preanal appendages along posterior edge of segment IX, but in L. tairomyenensis n sp. segment IX in dorsal view is triangular with distinctly convex preanal appendages along posterior edges of this segment. In dorsal view, segment X of L. chantaramongkolae is long and triangular, but short and tubular in the new species. Moreover, the harpago of L. chantaramongkolae appears distinctly longer than the subapical lobes of inferior appendages, but in the new species the harpago and subapical lobes are relatively similar in shape and length.	en	Suwannarat, Nannaphat, Malicky, Hans, Laudee, Pongsak (2020): Four new species of caddisflies (Trichoptera: Polycentropodidae, Psychomyiidae Hydropsychidae, Odontoceridae) from Khao Nan and Tai Rom Yen National Parks, southern Thailand.
