The male of this species is similar to that of D. burha distributed in southeastern Asia and Japan in genitalic morphology, but is easily distinguishable from the latter by the pair of long lateral filament of the abdominal segment V, and the pair of large internal gland of the segment VIII: Each lateral filament is approximately 2 times as long as segment V in this species, but is about 1.3 times as long as the segment in D. burha; and each internal gland is longer than the segment VII in this species, but is lacking in D. burha.</p> <p>Adult (Figs 1A–1L). Head and body (Fig. 1A) mostly dark brown, antennae with dark stripes; forewings black, with sparse white spots, spots around pterostigma larger (Fig. 1A), but indistinct for specimens preserved in alcohol. Head (Fig. 1B) with small round frontal setal wart (f.s.w.) and pairs of anterior and posterior setal warts; each anterior setal wart (a.s.w.) semicircular, mesal margin slightly concave; each posterior setal wart (p.s.w.) large, oval. Venation as in Figure 1C; forewings each 6.0–8.5 mm long in male (n = 10), 6.8–10.5 mm in female (n = 10), with postcostal region (posterior of looped anal veins) half as long as wing and wider than any wing cells; hind wings each with Sc and R1 veins bowed at pterostigma. Pair of lateral filaments (l.f.) of abdominal segment V (V) long, each approximately 2 times as long as segment V in male (Fig. 1D), 1.5 times in female. Segment V with small internal gland (i.g.) both in male and female. Segment VIII (VIII) with very large internal gland in male, apparently longer than segment VII (VII) (Fig. 1D), lacking in female.</p> <p>Male genitalia (Figs 1E–1I). Segment IX (IX) triangular in lateral aspect (Fig. 1E). Segment X (X) with pair of mesocaudal lobes (m.c.l.), separated apically in dorsal aspect (Fig. 1F), each with round apex in dorsal and lateral aspects (Figs 1E, 1F), with stout clavate setae; pair of lateral lobes (l.l.) projected outward in dorsal aspect (Fig. 1F), appearing jagged posteriorly because of tiny marginal spines, with short stout setae ventrally, shape of posterior margin in lateral aspect variable (Figs 1E, 1I); pair of preanal appendages (p.a.) large oval in lateral aspect (Fig. 1E), weakly bulging, setose. Inferior appendages (i.a.) each with basal segment long, extending beyond apex of segment X, gradually thickened from base to apex; distal segment about 1/3 as long as basal segment, tapering to apex, curved mesad (Fig. 1F). Phallic apparatus thick basally, narrow in middle (Fig. 1G); apex weakly bulging laterally in dorsal aspect (Fig. 1H), with two pairs of endothecal processes (e.p.) dorsally, each process ovate, dorsal pair larger than ventral pair.</p> <p>Female genitalia (Figs 1J–1L). Sternum VIII cleft from base, forming pair of lateral lobes (l.l.) widely separated from each other posteriorly in ventral aspect (Fig. 1L). Segment IX (IX) triangular in dorsal aspect (Fig. 1K), rhomboid in lateral aspect (Fig. 1J); with pair of long external sclerotized ribs (s.r.) ventrolaterally, weakly ridged (Figs 1J, 1L). Vulval scale (v.s.) tongue-like in ventral aspect (Fig. 1L), reinforced by sclerotized ribs basolaterally; apex membranous with small median bulge. Segment X (X) rhomboid in lateral aspect (Fig. 1J), anteroventral corner slightly protruding anteriorly.</p> <p>Immature stage. Diplectrona sp. DB described by Akagi (1956) is the larval stage of this species (Kagaya et al. 1998; Inazu &amp; Nishida 2011).</p> <p>Specimens examined.

Kibune-miyama-shima-tobikera.</p> <p>Remarks. Tsuda (1940) described this species based on two males collected from Kyoto, central Japan. Although I could not examine the type series materials of this species, which are likely lost, the male characteristics in the original description agree well with those of the male described above, especially the length of lateral filaments of abdominal segment V, and the shapes of mesocaudal lobes of segment X and inferior appendages.After comparative study of the type series males of Hydropsyche difficultata with specimens collected widely from Japanese main islands, I recognized that H. difficultata is the same species as D. kibuneana. Although the posterior margin of each lateral lobe of H. difficultata bears a ventral projection directed posterodorsad in lateral aspect (Kobayashi 1984, fig. 12; Fig. 1I), the shape is variable in D. kibuneana even in the same locality.</p> <p>In the collection of the late Mr. Kobayashi deposited in the Kanagawa Prefectural Museum of Natural History, the holotype and paratype males of H. difficultata were preserved together in the same vial with two handwritten labels reading “7262 ♂.” A male without abdomen and a cleared abdomen in the vial must have been used in the original description by Kobayashi (1984). I added a label “ HOLOTYPE labeled by T. Nozaki, 2021” into this vial and another male was moved into a different small vial with labels, “7262 ♂ ” and “ PARATYPE labeled by T. Nozaki, 2021.”</p> </div>	http://treatment.plazi.org/id/854F87B5FFFB681EFF0AB941FE96ADF9	Public Domain	No known copyright restrictions apply. See Agosti, D., Egloff, W., 2009.

The male of this species is similar to that of D. albofasciata known from Taiwan and the southernmost islands of Japan, and Diplectrona wangyipingi Sun 2017, described from China. However, the male is easily distinguishable from the latter two species by the shape of the phallotheca: the phallotheca bears a pair of prominent apicolateral lobes in this species, but it lacks such lobes in D. albofasciata and D. wangyipingi. Furthermore, the length of the internal gland is longer than segment VII in this species, but shorter than the segment in D. albofasciata and D. wangyipingi; and the length of the lateral filaments is approximately the same length as segment V in this species, but longer than the segment in D. wangyipingi.</p> <p>Adult (Figs 4A–4M). Head and body (Figs 4A, 4B) mostly dark brown; antennae with dark stripes, but apical half paler. Forewings dark brown to black with white markings, but markings variable: on Shikoku usually with 3 large white markings (Fig. 4A), but occasionally indistinct (4B); on Honshu with sparse white spots similar to those on D. kibuneana (Fig. 1A). On head, frontal setal wart (f.s.w.) small oval, each anterior setal wart (a.s.w.) divided into 2 warts (Fig. 4C), anterior one long oval but often divided into 2 small warts (Fig. 4D), posterior one triangular; each posterior setal wart (p.s.w.) large oval. Forewings each 5.0–7.2 mm long in male (n = 10), 5.5–8.2 mm in female (n = 10), venation similar to that of D. kibuneana (Fig. 1C). Pair of lateral filaments (l.f.) of abdominal segment V (V) short, each approximately same length as segment V in both male and female (Fig. 4E). Segment V with small internal gland (i.g.) in both male and female (Fig. 4E). Segment VIII (VIII) with internal gland in male, very large, longer than segment VII (VII) (Fig. 4E), lacking in female.</p> <p>Male genitalia (Figs 4F–4J). Segment IX (IX) in lateral aspect (Fig. 4F) narrow, anterior margins gently convex anterad, posterior margins sinuate in ventral half.

Kyushu, Fukuoka: 11 males, Mt. Hiko-san, Soeda-machi, 19.v.1993, N. Kuhara (KuN).</p> <p>Remarks. Banks (1906) described Arctopsyche japonica based on specimens collected from Hikosan, Buzen (now Fukuoka, Kyushu), and a figure of distinct yellow markings of the left forewing was provided. He also recorded this species from Gifu, central Honshu, but precise data were not provided (Banks 1906). Ulmer (1907) transferred this species to the genus Diplectrona based on examination of males collected from Gifu, which have similar markings to the illustration by Banks (1906). However, according to photographs of a syntype male collected from Hikosan, and deposited in the Museum of Comparative Zoology, Harvard University (Figs 5A–5D: photographed by C. W. Farnum), the male bears a club-like process on each anterolateral corner of abdominal sternum V (s.V) (marked with an arrow in Fig. 5B). Furthermore, in male genitalia (Fig. 5C), each inferior appendage (i.a.) is onesegmented, and the large phallic apparatus (ph.) bears long spine-like processes. Males collected from the same area as the syntype male was collected have the same genitalic morphology (Fig. 5E). This species therefore belongs to the genus Homoplectra, and not to Diplectrona.</p> <p>After the publication by Banks (1906), many authors recorded D. japonica based on the characteristic markings of the forewings; however, Kawase &amp; Morita (2014) noted that multiple species have this character. This taxonomic problem warrants future work.</p> </div>	http://treatment.plazi.org/id/854F87B5FFF36814FF0ABAF9FE58AEFF	Public Domain	No known copyright restrictions apply.

Honshu, Gifu: 1 female, Ozu, Ibigawa-cho, 14–16.v.2001, N. Kawase (NK); 1 female, Nishimaenotani, Tsurumi, Ibigawa-cho, 10.iv.2002, N. Kawase (NK). Shiga: 45 females, Yuzurio, Eigenji, Higashi- Omi-shi, 12–31.v.2009, N. Kawase, by Malaise trap (MITR20090430).</p> <p>Remarks. Ulmer (1907) described this species as a member of the genus Diplectrona based on a female specimen collected from an unknown locality in Gifu, central Honshu, and provided only a general description without illustrations. In 2021, I obtained photographs of the holotype of this species deposited in the Royal Belgian Institute of Natural Sciences, Brussels (Figs 6A–6D: photographed by J. Lalanne). Although the specimen lacks her head, her abdomen retains the following characteristics: Abdominal sternum V (s.V) bears a club-like process near the anterolateral margin (marked with an arrow in Fig. 6B), the vulvar scale (v.s.) bears a pair of plate-like lobes basally (marked with a black arrow in Fig. 6C), and a large pocket-like concavity between segment IX and vulval scale (marked with a white arrow in Fig. 6C). Through the course of my study, I obtained females collected in Gifu, which have these characters (the latter two characters marked with arrows in Fig. 6E). Their morphology, such as stout antennae, shape of wings, wing venation, etc., suggests that this species does not belong to the genus Diplectrona, but to Homoplectra. Although the markings of the forewings of the holotype female are indistinct (Fig. 6A), the two females examined in this study have forewings with distinct yellow markings similar to those of H. japonica.</p> <p>Furthermore, 45 females collected from Shiga, an adjacent district of Gifu, have the same genitalic morphology as the holotype and 36 of these females bear the distinct markings, but 9 of them lack the markings. Redescription of this species in detail, including the variation of wing coloration, warrants future study.</p> </div>	http://treatment.plazi.org/id/854F87B5FFF36816FF0ABE16FBEBAAB9	Public Domain	No known copyright restrictions apply.
