Type material.

Rhaphidopalpa angulicollis : Unavailable for study. The type specimens are not present in the Zoological Museum of Moscow State University ( Medvedev 2006, 2014, personal communication) or in the Zoological Institute in Saint Petersburg (Moseyko 2014, personal communication).

Semacia nipponensis : Lectotype male (MNHN), pinned, here designated to fix the concept of Semacia nipponensis and to ensure the universal and consistent interpretation of the same, labeled: "MUSEUM PARIS [p] / NIPPON MOYEN [p] / ENV.

Diagnosis.

See diagnosis of Paridea (Semacia) kaoi sp. n.

Males.

Length 5.1-5.5 mm, width 3.1-3.3 mm. Head and prothorax yellowish brown (Figs 96-98), labrum black, antenna brown; scutellum pale yellow; elytra pale yellow, with deep excavation behind scutellum at suture; with one extremely slender black stripe along suture behind excavation, sometimes reduced; with one pair of large black spots subapically, lateral margin and epipleuron black, extending posterior and connected with subapical black spots; meso- and metathoracic ventrites black; legs dark brown, apex of femur and base of tibia paler; abdomen yellow. Eighth abdominal tergite (Fig. 107) strongly sclerotized, transverse and slender, with one pair of extremely slender and curved processes. Pygidium slightly projecting beyong elytral apices. Penis slightly asymmetric, slightly narrowed at apical 1/6; apex narrow, tubular, and small; straight from lateral view; endophallic sclerites with one pointed sclerite, one elongate sclerite, and a cluster of large setae.

Females.

Lenth 5.1-5.6 mm, width 3.0-3.4 mm. Similar to male (Fig. 99), elytra without excavation but black spot instead. Apical margin of last abdominal ventrite (Fig. 106) with one pair of small rounded processes at middle, slightly emarginate outside processes. Pygidium slightly projecting beyong elytral apices. Gonocoxae (Fig. 104) slender, apex of each gonocoxa with eight setae from apical 1/7 to apex; connection of gonocoxae extremely slender, base widened. Sternite VIII (Fig. 105) weakly sclerotized; apex narrow, apical margin emarginate at middle, surface with dense long setae along apical margin, spiculum short. Spermathecal receptaculum (Fig. 108) slightly swollen; pump much longer than receptaculum, strongly curved; spermathecal duct short, stout, shallowly projecting into receptaculum.,

Distrbution.

Japan, China (Jiangxi, Hubei, Sichuan). Yang (1991) indicated that this species was also found in Zhejiang, Fujian, Hainan, and Guanxi provinces of China. These records are dubious since no voucher specimens were examined and Japanese populations were misidentified as Paridea (Semacia) nigrimarginata Yang, 1991 (see below).

Host plants.

Cucurbitaceae : Gynostemma pentaphyllum (Thunb.) Makino, Trichosanthes cucumeroides (Ser.) Maxim. ex Fr. & Sav. ( Chûjô and Kimoto 1961).

Notes.

The position of the type locality of Paridea (Semacia) nigrimarginata was doubtful since information on the label is insufficient. Only "Mt. Takao" appears on the label and Beenen (2010) supposed that it was located in Taiwan since “Takao” is the Japanese name for Kaoshiung City, but Kaoshiung city it is not a mountain. Mt. Takao probably refers to a locality in Japan since a famous mountain (Mt. Takao-Yama, Takao-machi, Hachioji-shi, Tokyo Prof., Japan) exists there with similar names. Moreover, subsequent material (see specimens examined) came from this locality with additional information indicating the Japanese Mt. Takao.
