Theopea louwerensi Jolivet, 1951: 4; Wilcox, 1973: 631 (catalogue); Kimoto, 1990: 234 (catalogue).

Types. Holotype ♂ (IRSB, original designation): “PELITOERAN / RES. KEDIRI / E. JAVA [p, w, with red border] // Theopea / sp / m pulchella / Baly [h] / P. Jolivet det., 195[p]0 / Theopea / louwerensi / Jolivet [h, w] // TYPE [p, pink label] // R. I. S. Nat. Belg. / I. G. [p] 18.068 [h, w]”. Paratype: 1♂ (IRSB): “DANGLEM / RES. KEDIRI / E. JAVA [p, w. with red border] // ALLOTYPE [p, r]”. Jolivet (1951) indicated incorrectly that the paratype is a female.

Redescription. Length 6.3–7.0 mm, width 2.3– 2.2 mm. General color (Figs 5A, 5B) brown to blackish brown; antenna entirely blackish brown; elytra and pronotum metallic blue. Antennae filiform in males, antennomeres VI slightly broadened apically, VII and VIII strongly swollen, VII with lateral process near apex, VIII with lateral process at basal 1/3 (Fig. 6A), length ratios of antennomeres I–XI 1.0: 0.3: 0.9: 1.0: 1.0: 0.9: 1.0: 0.9: 0.9: 0.9: 1.1, length to width ratios of antennomeres I–XI 3.0: 1.3: 3.3: 3.3: 3.2: 2.5: 2.0: 1.9: 3.7: 3.7: 4.7; filiform in females (Fig. 6B), VI to VIII slightly swollen, length ratios of antennomeres I–XI 1.0: 0.3: 0.7: 0.8: 0.8: 0.7: 0.9: 0.9: 0.8: 0.8: 0.9, length to width ratios of antennomeres I–XI 3.6: 1.6: 3.2: 3.8: 3.6: 2.9: 3.2: 3.2: 3.7: 3.6: 4.4. Elytra elongate and parallel-sided, 2.1x longer than wide; disc with weak dense, coarse punctures, arranged into longitudinal rows, with one weak longitudinal ridge between two longitudinal rows of punctures. Tarsomeres I of front legs slightly swollen in males. Aedeagus (Figs 6 C–6E) broad, 5.5x longer than wide; apex lanceolate, with median, deep, wide notch, from apex to apical 1/4, broadened at middle; sides widest at apical 1/4, gradually narrowed towards basal 1/4; tectum well sclerotized, abruptly narrowed near apex, apex narrowly rounded, recurved in lateral view; straight in lateral view, slightly curved near base; triangular sclerites small; internal sac with one median, elongate sclerite, apex acute, basally connected with laterally flattened sclerite, covered with stout setae. Gonocoxae (Fig. 6G) elongate, widest at apical 1/8, both gonocoxae combined together from basal 1/7 to apical 1/7; apices narrowly rounded, each gonocoxa with eight setae along outer margin from apex to apical 1/7; with one pair of short lateral processes at basal 2/5. Ventrite VIII (Fig. 6F) elongate and well sclerotized; disc with several long setae laterally and near apical margin, and with dense, short setae along apical margin; spiculum extremely slender. Receptacle of spermatheca (Fig. 6H) strongly swollen; pump slender and strongly curved; proximal spermathecal duct deeply inserted into receptacle, narrow and short.

Variations. Some specimens have metallic purple bodies and three apical white antennomeres (Fig. 5C).

Diagnosis. Adults of T. louwerensi are easily recognized by their metallic green or blue pronota and presence of lateral processes on antennomeres VII and VIII in males.

Distribution. Indonesia: Java.
