The first author, Mrs Hsueh Lee, and Mr Hou-Jay Chen found young larvae feeding on tender shoots (Fig. 9 A) April 1, 2009 in Lalashan, northern Taiwan. mature larvae started to burrow into soil and built underground chambers for pupation April 11. The newly eclosed adults emerged from soil April 28. The first author and Mr. Ta-Hsiang Lee found the host plants blooming and sprouting at the same time (Fig. 9 B) April 21, 2010 in Tahsuehshan, central Taiwan. Many larvae were found inside flower buds with holes (Fig. 9 C, D). Some larvae preferred to feed on pedicels (Fig. 9 E). Newly emerged adults appeared during late spring, into summer (Fig. 9 F).	en	Lee, Chi-Feng, Bezdek, Jan (2021): Revision of the genera Xanthogaleruca Laboissiere, 1932 and Pyrrhalta Joannis, 1865 (Coleoptera, Chrysomelidae, Galerucinae) of Taiwan, with type designation of Galerucella lineatipes Takei.

Females deposited single eggs in crevices of small twigs (Fig. 44 A) or a hole prepared by the female (Fig. 44 B) during autumn. The larvae hatched when plants sprouted during spring. They prepared a hole as a resting site (Fig. 44 C). They exited the hole only when feeding on leaves (Fig. 44 D). Larval duration was 14 days. mature larvae burrowed into soil and built underground chambers for pupation. Duration of the pupal stage (Fig. 44 E) was 22 - 28 days. Newly emerged adults appeared during spring and were active (Fig. 44 F) during summer and autumn.	en	Lee, Chi-Feng, Bezdek, Jan (2021): Revision of the genera Xanthogaleruca Laboissiere, 1932 and Pyrrhalta Joannis, 1865 (Coleoptera, Chrysomelidae, Galerucinae) of Taiwan, with type designation of Galerucella lineatipes Takei.

Females began to deposit an average of 10 - 20 eggs in single egg mass (Fig. 52 A) during middle March. Larvae hatched in 7 days. The larvae (Fig. 52 B) fed on leaves and the larval duration was 14 days. mature larvae (Fig. 52 C) burrowed into soil and built underground chambers for pupation. Duration of the pupal stage (Fig. 52 D) was 28 - 30 days. Newly emerged adults (Fig. 52 E) were yellowish brown and appeared during spring and were active (Fig. 52 F).

Body color (Fig. 1 D-F) yellowish brown; vertex with one rounded black spot at middle, antennae blackish brown but ventral discs of antennomeres IV-VI brown; pronotum with three large black spots, one spot at center, from apical 1 / 4 to basal 1 / 4, apically broadened, two spots laterally; scutellum black; elytra metallic green. Eyes relatively large, interocular space 2.33 - 2.45 x diameter of eye. Antennae filiform in males (Fig. 3 A), length ratios of antennomeres I-XI 1.0: 0.5: 0.6: 0.8: 0.8: 0.7: 0.7: 0.6: 0.6: 0.6: 0.7, length to width ratios of antennomeres I-XI 3.1: 2.1: 2.5: 2.9: 3.1: 2.9: 3.0: 2.6: 2.8: 2.7: 3.4; similar in females (Fig. 3 B), length ratios of antennomeres I-XI 1.0: 0.4: 0.6: 0.7: 0.7: 0.7: 0.7: 0.6: 0.6: 0.6: 0.8, length to width ratios of antennomeres I-XI 3.4: 1.9: 2.5: 3.0: 2.8: 2.8: 2.8: 2.6: 2.6: 2.5: 3.4. Pronotum and elytra dorso-ventrally depressed. Pronotum 1.9 - 2.0 x wider than long, disc smooth, with dense coarse punctures and short pubescence, with lateral depressions; lateral margins moderately rounded, apical margin slightly concave, basal margin straight. Elytra elongate, parallel-sided, 1.7 - 1.8 x longer than wide; disc smooth, with dense, fine punctures and short pubescence, with three indistinct longitudinal ridges, two near suture, one from humerus. Apical spur of tibia of middle leg elongate in males (Fig. 3 K); tarsomeres I of front and middle legs apically broadened in males (Fig. 3 I), less broadened in females (Fig. 3 J). Aedeagus (Fig. 3 C, D) slender in dorsal view, 5.8 x longer than wide, sides asymmetric, gradually broadened from apex to apical 1 / 4, slightly narrowed at middle, apex broadly rounded; moderately curved near base in lateral view, moderately broadened from apex to middle, apex narrowly rounded; ostium covered by a more or less sclerotized membrane; primary endophallic sclerite long, 0.7 x as long as aedeagus, with four apical teeth, and an additional longitudinal row of erect teeth from near apex to base, becoming smaller towards apex, one short sclerite connected with base, apex with one short tooth. Gonocoxae (Fig. 3 E) transverse, both gonocoxae combined from basal connection, with a number of short setae along apical margin. Ventrite VIII (Fig. 3 F) extremely transverse; disc with dense, short setae along apical margin; spiculum extremely short. Receptacle of spermatheca (Fig. 3 L) very swollen; pump short and strongly curved; sclerotized proximal spermathecal duct wide and short. Apical margin of abdominal ventrite V with angular depression at middle in males, followed by shallow notch (Fig. 3 H); represented by a semi-circular depression in females (Fig. 3 G).	en	Lee, Chi-Feng, Bezdek, Jan (2021): Revision of the genera Xanthogaleruca Laboissiere, 1932 and Pyrrhalta Joannis, 1865 (Coleoptera, Chrysomelidae, Galerucinae) of Taiwan, with type designation of Galerucella lineatipes Takei.

D788D1B795B85112B429F76DE59C6532.taxon	biology_ecology	Biology. Xanthogaleruca yuae sp. nov. populations are presumed to be univoltine. The following life cycle information is based on our (TCRT) observations made by Mr Mei-Hua Tsou (Lee and Cheng 2010). Females began to deposit an average of 10 - 20 eggs in two rows of a single egg mass on the undersides of leaves (Fig. 4 A) during 22 April 2009. Larvae hatched in 7 - 8 days. Larvae fed on one side of leaves and left only one layer of tissue at the surface (Fig. 4 B, C). The larval duration was 15 - 21 days. mature larvae (Fig. 4 D) expelled an adhesive from the anus, then pupated on the undersides of leaves. Duration of the pupal stage was 8 - 13 days (Fig. 4 E). adults were active during spring (Fig. 4 F).	en	Lee, Chi-Feng, Bezdek, Jan (2021): Revision of the genera Xanthogaleruca Laboissiere, 1932 and Pyrrhalta Joannis, 1865 (Coleoptera, Chrysomelidae, Galerucinae) of Taiwan, with type designation of Galerucella lineatipes Takei.
