Diagnosis.

Jolibrotica chujoi is similar to Jolibrotica sauteri but differs by its shiny black color and wider penis.

Males.

Length 3.2-3.8 mm, width 1.2 mm. Color blackish brown (Figs 17-19). Eyes small, distance between eyes 4.3 times wider than diameter of eye. Antenna (Fig. 23) filiform and long, as long as body size, ratio of length of antennomeres III to XI about 1.0: 1.2: 1.2: 1.1: 1.1: 1.0: 0.9: 0.9: 1.1; ratio of length to width from antennomere III to XI about 2.8: 3.1: 3.1: 3.0: 3.0: 2.7: 2.8: 2.7: 3.6. Pronotum quadrilateral; 1.47-1.54 times wider than long; widened anteriorly; disc moderately depressed behind middle. Elytra elongate, 1.66-1.69 times longer than wide; wid est at apical 1/3. First tarsomeres normal. Abdominal ventrites without modification, ventrite V with apical margin truncate. Penis (Figs 25, 26) elongate, about 6.8 times longer than wide, apex rounded with small distinct tip, widest at apical 1/10, towards base gradually narrowed; tectum membranous; ventral surface with longitudinal median area membranous; extremely slender and slightly curved behind mddile at lateral view; internal sac with one longitudinal sclerite, apex forming inwards forked processes, base deeply bifurcate.

Females.

Length 4.1-4.3 mm, width 2.1-2.2 mm. Similar to male (Figs 20-22); antenna relatively slender than in male (Fig. 24), about 0.9 times as long as body, ratio of length of antennomeres III to XI about 1.0: 1.0: 0.9: 0.9: 0.9: 0.8: 0.8: 0.8: 1.1; ratio of length to width from antennomere III to XI about 3.6: 3.6: 3.2: 3.2: 3.2: 3.0: 3.0: 2.9: 3.3. Apical margin of ventrite V truncate. Gonocoxae (Fig. 27) slender, well separated from each other, combined together from apical 2/5 to 3/5; each gonocoxa with seven setae from apical 1/6 to apex. Ventrite VIII (Fig. 28) only laterally sclerotized; apical margin widely rounded, with several long setae near lateral margins, and several long and dense setae mixed along apical margin. Spermathecal receptaculum (Fig. 29) extremely swollen; pump extremely slender and curved; sclerotized spermathecal duct short and wide.

Distribution.

Endemic to southern Taiwan below 1500 m elevation (Fig. 15).

Host plant.
