Gonioctena (Gonioctena) kamikawai ( Chûjô, 1958)

( Figs 5 View FIGURES 5–6 , 10 View FIGURES 7–11 , 12 View FIGURE 12 )

Phytodecta (Phytodecta) kamikawai Chûjô, 1958: 72 (original description).

Gonioctena (Gonioctena) kamikawai: Kimoto 1969: 22 ; Kimoto & Chu 1996: 53; Kimoto 1986: 56; Kimoto & Takizawa 1997: 158, 295, 369, 492, 541 (incl. larva, biology); Lee & Cheng 2010: 59 (incl. larva, pupa, biology, host plant); Kippenberg 2010: 433; Yang et al. 2014: 364 (part); Yang et al. 2015: 50 (part).

Gonioctena kamikawai: Kimoto 1987: 187 ; Takizawa et al. 1995: 7.

Type locality. Taiwan: Hualien County, Fenglin .

Type material. Holotype: ♀ ( TARI), “ Phytodecta kamikawai Chûjô DET. M. CHUJO // HOORIN FORMOSA 10. VIII. 1934 COL. M. KAMIKAWA // Holotype // 697”.

Other material examined. 1 ♀ ( HCC), (Taiwan) Fenchihu , 1400m, Chiayi Hsien, 13.IV.1965, T. Shirozu ; 1 ♂, 1 ♀ ( SEHU), Chihtuan, Ilan , Taiwan, 15.V.1984, Y. Komiya lgt .; 1 ♂, 1 ♀ ( MNHW), Taiwan, Tehwasha , 15.V.1977, J. Ito lgt .

Diagnosis. This species is similar to G. fujiana and G. jolantae new species in that it has nine black spots on the pronotum and the elytral punctures are arranged in confused single or double rows. However, G. kamikawai can be distinguished by the following characters: irregular yellowish-brown marking on elytral humerus extending across 1/3–3/5 of elytral base (to 1/2 of base in G. fujiana , to 3/5 of base in G. jolantae new species); median lobe subparallel-sided with apical process narrower than shaft, lateral angles of process distinct (parallel-sided with apical process broader than shaft, lateral angles of process distinct, in G. fujiana ; subparallel-sided with apical process narrower than shaft, lateral angles of process rounded, in G. jolantae new species).

Distribution. China: Taiwan ( Fig. 12 View FIGURE 12 ).

Host plants. Alnus formosana (Burkill) Makino (Betulaceae) and Lithocarpus hancei (Benth.) Rehder (Fagaceae) ( Lee & Cheng 2010).

Remarks. Kimoto & Takizawa (1997) reported that adults collected in Kaohsiung County, Taiwan, in late March laid yellowish-white eggs. To date, Gonioctena kamikawai is the only known oviparous species within the nominotypical subgenus; all other species are ovoviviparous ( Cho 2019).
