Diagnosis.

Although Haplosomoides shirozui resembles Haplosomoides changi Lee, Bezděk & Staines, 2011 with the similarly peculiar shaped penis and absence of longitudinal ridge on the elytron, it can be easily recognized by its metallic blue elytra (pale in Haplosomoides changi , see Lee et al 2011).

Males.

Length 4.1-5.1 mm, width 1.4-1.7 mm. Color yellowish-brown (Figs 30-32); antenna blackish-brown, three or four basal antennomeres paler; elytron metallically blue; metathoracic and abdominal ventrites black. Eyes extremely small, distance between eyes 3.7 times wider than diameter of eye. Antenna (Fig. 33) filiform and long, 0.9 times as long as body size, ratio of length of antennomeres III to XI about 1.0: 1.3: 1.3: 1.2: 1.2: 1.2: 1.0: 1.0: 1.3; ratio of length to width from antennomere III to XI about 2.6: 3.3: 3.4: 3.2: 3.3: 3.1: 2.8: 2.7: 3.9. Pronotum quadrilateral; 1.33-1.47 times wider than long; widened anteriorly; disc moderately depressed behind middle. Elytra elongate, 2.17-2.23 times longer than wide; parallel-sided. First tarsomeres normal. Abdominal ventrites without modification, ventrite V with apical margin truncate. Penis (Figs 35, 36) abruptly widened at middle, apex pointed, with median and wide groove from near apex to middle, central area membranous; ventral surface with longitudinal ridges close to lateral margin from apex to middle; moderately curved from lateral view.

Females.

Length 5.7-5.9 mm, width 2.0-2.2 mm. Similar to male; ratio of length of antennomeres III to XI about 1.0: 1.3: 1.2: 1.1: 1.1: 1.1: 0.9: 0.9: 1.2; ratio of length to width from antennomere III to XI about 2.9: 3.8: 3.4: 3.3: 3.3: 3.2: 2.7: 2.8: 3.9 (Fig. 34). Apical margin of ventrite V widely rounded. Gonocoxae (Fig. 37) slender, extremely close to each other from apex to apical 1/4, each gonocoxa with seven to eight setae from apical 1/6 to apex; basally combined from base to apical 1/4. Ventrite VIII (Fig. 38) with lateral and apical margin strongly sclerotized; apical margin emarginate, with several long setae along lateral margins, and one cluster of short setae at antero-lateral angles. Spermathecal receptaculum (Fig. 39) as wide as pump; pump hardly separated from rectptaculum, moderately curved; sclerotized spermathecal duct slender and extremely long.

Distribution.

Endemic to Taiwan. Although not as widespread as Jolibrotica sauteri , it is abundant locally in mountains at elevations between 1000 and 2500 m, extending north to Hsinchu County.

Host plant.

Clerodendrum trichotomum Thunb ( Verbenaceae ).

Discussion.

Phyllobrotica shirozui is transferred to Haplosomoides based on male abdomen simple (strongly modified in Phyllobrotica ), pronotum with wide transverse depression in posterior half (pronotum regularly convex in Phyllobrotica ) and elytral epipleura present (absent in Phyllobrotica ). Haplosomoides shirozui belongs to Haplosomoides annamita species group as defined by Lee et al (2011) and in the structure of aedeagus it is very close to Haplosomoides changi Lee, Bezděk & Staines, 2011.
