Redescription. Length 4.9–6.0 mm, width 1.7–2.1 mm. General color ( Figs 2 View FIGURES 2 D–2F) yellowish brown; antennae dark brown; elytra metallic green; vertex and pronotum with metallic green iridescence, strong in some individuals, sometimes darkened and more subdued. Vertex with reticulate microsculpture. Antennae filiform in males ( Fig. 7A View FIGURES 7 ), length ratios of antennomeres I–XI 1.0: 0.3: 0.8: 0.9: 1.0: 1.0: 1.0: 1.0: 1.0: 0.8: 1.0, length to width ratios of antennomeres I–XI 3.4: 1.5: 3.9: 4.2: 4.9: 4.8: 4.8: 5.0: 5.3: 4.7: 5.7; slender in females ( Fig. 7B View FIGURES 7 ), antennomeres III–X straight, length ratios of antennomeres I–XI 1.0: 0.3: 0.8: 1.0: 0.9: 0.9: 0.9: 0.9: 0.8: 0.8: 0.8, length to width ratios of antennomeres I–XI 4.0: 1.6: 4.4: 5.5: 5.9: 5.6: 5.6: 5.8: 5.1: 4.7: 5.3. Pronotum transverse, 1.4x wider than long, disc with reticulate microsculpture, dense, coarse punctures, and one pair of lateral depressions; lateral margin basally narrowed; apical and basal margins subtruncate. Elytra elongate and parallel-sided, 2.1–2.2x longer than wide; disc with reticulate microsculpture, dense, coarse punctures, arranged into longitudinal rows, with distinctly longitudinal ridges between longitudinal rows of punctures. Apical margin of abdominal ventrite V in females rounded but slightly depressed near medial area ( Fig. 7I View FIGURES 7 ). Tarsomeres I of front legs swollen in males ( Fig. 7J View FIGURES 7 ), subparallel in females ( Fig. 7K View FIGURES 7 ). Penis ( Figs 7 View FIGURES 7 C–7F) extremely slender, 12.3x longer than wide; widest at apex, obliquely truncate in dorsal or ventral view, curved ventrally in lateral view, apically tapering in frontal view; parallel-sided; tectum short from apical 1/10 to 1/4, apically narrowed; medially curved in lateral view; triangular sclerites small; internal sac with one narrow, short endophallic sclerite complex, 0.4x as long as penis, composed of two sclerites, basal piece much longer (1.6x) than apical piece, apical piece with incised apex, dorsal sclerites paired, apices acute. Gonocoxae ( Fig. 7G View FIGURES 7 ) elongate, slightly broadened subapically, connected from basal 1/3 to apical 1/5; apices narrowly rounded, each gonocoxa with eight setae along outer margin from apex to apical 1/6; with one pair of short lateral processes at basal 2/5. Ventrite VIII ( Fig. 7H View FIGURES 7 ) longitudinal and well sclerotized; disc with several long setae at sides, and with dense, short setae along apical margin; spiculum extremely slender. Receptacle of spermatheca ( Fig. 7L View FIGURES 7 ) strongly swollen; pump slender and strongly curved; proximal spermathecal duct deeply inserted into receptacle, broad and short.

Variation. The elytra of specimens collected in southern Taiwan ( Fig. 6B View FIGURES 6 ) are brown ( Figs 2G, 2H View FIGURES 2 ). The metallic green iridescence of the vertex, pronotum, and elytra is widely variable.

Food plants. Lauraceae : Lindera akoensis and Neolitsea parvigemma ( Fig. 1C View FIGURES 1 ).

Diagnosis. Theopea collaris adults are similar to those of T. aureoviridis in color and presence of extremely coarse punctures on the elytra. They can be distinguished by the presence of longitudinal ridges on the elytra and yellowish brown vertex and pronotum with more or less metallic green iridescence ( Figs 2 View FIGURES 2 D–2H) (reduced longitudinal ridges on the elytra and metallic green vertex and pronotum in T. aureoviridis ( Figs 2 View FIGURES 2 A–2C)). Males of T. collaris are characterized with the obliquely truncate apex of the penis and paired dorsal sclerites ( Figs 7 View FIGURES 7 C–7F) which differ from those of other species in possessing bifurcate apices of the penis and single hook-like dorsal sclerite.

Distribution. South Taiwan (Kaohsiung and Pingtung counties) below 1000 m ( Fig. 6B View FIGURES 6 ). Adults appears from March to July, but most (86%) are present during April and May.
