03B77C31FFF98F4B87E33FD818D23A27.taxon	description	Adult habitus. General color dark brown to black, typical of genus. Male. Forewing length 6 mm. Epiproct short in dorsal aspect, slender and bent sharply near midlength in lateral aspect (Figs. 1, 3). Sclerite of tergum 9 broadly excavated posteromesally, small knobs absent from tergum 10 (Fig. 1). Cerci bearing a small dorsobasal lobe and a small apical spine (Figs. 1 - 3). Paraprocts fused into a broad, thick process, bent dorsad at a right angle on the ventrocaudal margin (Fig. 3). Apex of sternum 9 triangular in ventral aspect (Fig. 2) and curved upward in lateral aspect (Fig. 3). Vesicle short and rounded on apical margin. Female. Forewing length 7 mm. Posterior margin of sternum 7 produced into a rounded or slightly triangular projection which slightly overlaps the base of sternum 8. Sternum 8 bearing a pair of median, rectangular shaped sclerites, narrowly separated by a membranous strip; sclerites extend over apex of sternum 9 (Fig. 4); basolateral wing-like sclerites attached at mesolateral margins of median sclerites. Larva. Undescribed.	en	Sivec, Ignac, Stark, Bill P. (2012): The Genus Perlomyia Banks In Taiwan (Plecoptera: Leuctridae). Illiesia 8 (11): 119-124, DOI: http://doi.org/10.5281/zenodo.4760611
03B77C31FFF98F4B87E33FD818D23A27.taxon	etymology	Etymology. The species name refers to the angular form of the epiproct in lateral aspect.	en	Sivec, Ignac, Stark, Bill P. (2012): The Genus Perlomyia Banks In Taiwan (Plecoptera: Leuctridae). Illiesia 8 (11): 119-124, DOI: http://doi.org/10.5281/zenodo.4760611
03B77C31FFF98F4B87E33FD818D23A27.taxon	diagnosis	Diagnosis. Perlomyia angulata does not appear to be closely related to any of the known species. The strongly bent epiproct in lateral aspect, with blunt apex and the absence of knobs on tergum 10 is apparently unique to this species. Among Taiwanese species the male is more similar to P. taiwanensis (described below) but that species lacks the slender angular epiproct and also has knobs on tergum 10. Females are similar to P. excavata in having abdominal sternum 7 projecting over the base of 8, but these are distinct by virtue of the lateral winglike sclerites of sternum 8 being connected to the posterolateral margins of the median sclerites in P. angulata but connecting to the anterolateral margins in P. excavata.	en	Sivec, Ignac, Stark, Bill P.

03B77C31FFFA8F4A85653BEC1EBD39C0.taxon	etymology	Etymology. The species name refers to the U-shaped, excavated area of tergum 9 of the male.	en	Sivec, Ignac, Stark, Bill P. (2012): The Genus Perlomyia Banks In Taiwan (Plecoptera: Leuctridae). Illiesia 8 (11): 119-124, DOI: http://doi.org/10.5281/zenodo.4760611
03B77C31FFFA8F4A85653BEC1EBD39C0.taxon	diagnosis	Diagnosis. This is the only known Perlomyia species in which the male 9 th tergum exhibits a U-shaped cleft, similar to that found in males of the eastern Nearctic genus Zealeuctra (Ricker & Ross 1969). A similar structure also occurs on tergum 7 for Leuctra fusca (Linnaeus) (Zhiltzova 2003 a). As noted above the female is similar to P. angulata among Taiwanese species, but is distinguished by the location of the attachment points between sclerites on sternum 8.	en	Sivec, Ignac, Stark, Bill P.

03B77C31FFFA8F4D87F7392C18C43DE6.taxon	etymology	Etymology. The species name is based on the type locality on the island of Taiwan.	en	Sivec, Ignac, Stark, Bill P. (2012): The Genus Perlomyia Banks In Taiwan (Plecoptera: Leuctridae). Illiesia 8 (11): 119-124, DOI: http://doi.org/10.5281/zenodo.4760611
03B77C31FFFA8F4D87F7392C18C43DE6.taxon	diagnosis	Diagnosis. This species is the only one of the known Taiwanese species of Perlomyia in which males have knobs on tergum 10. This character is shared with both Nearctic species and with several from Asia, however, the epiproct shape will distinguish this species from all known members of the genus. Females are generally similar to others from Taiwan but differ in having the lateral wing-like sclerites of sternum 8 attached along the entire length of the mesal sclerites.	en	Sivec, Ignac, Stark, Bill P.
