Theopea fairmairei Duvivier, 1885

( Figs 16 , 17 )

Theopea fairmairei Duvivier, 1885a: 248 ; Weise, 1924: 151 (catalogue); Wilcox, 1973: 630 (catalogue); Kimoto, 1990: 234 (catalogue).

Types. L ectotype ♂ (BMNH), here designated, labeled: “6 [h, w] // Ozomena / Fairmairei / Duvivier / Java [h, w] // Types ex / Coll. Fairmaire / Stett. Ent. Zeit. / ??? [some unreadable letters] / XLVI p.248 [h, one the back of the same label] // Baly Coll. [p, w]. The labels were written by Baly who exchanged type specimens with many authors, including Duvivier. Although the species name on the label is Ozomena Fairmairei , the valid combination is Theopea fairmairei as presented in the original publication. The number of syntypes is uncertain. Types of this species cannot be found at the French National Museum of Natural History (Antoine Mantilleri, personal communication, VIII.8.2018).

Redescription. Length 6.0– 6.6 mm, width 2.3–2.7 mm. General color ( Figs 16 A–16C) yellowish brown to dark brown; antennae entirely blackish brown; elytra metallic green; abdomen, tibiae and tarsi dark brown. Antennae filiform in males, but antennomeres VI–VIII strongly swollen, IX and X with small processes at middle of lateral margins ( Fig. 17A ), length ratios of antennomeres I–XI 1.0: 0.3: 0.7: 0.9: 0.9: 1.0: 1.0: 0.9: 0.8: 0.8: 1.1, length to width ratios of antennomeres I–XI 2.9: 1.3: 2.4: 2.9: 3.0: 2.8: 2.6: 2.7: 2.7: 3.1: 5.3; filiform in females ( Fig. 17B ), VI–VII relatively broader, length ratios of antennomeres I–XI 1.0: 0.3: 0.7: 0.9: 0.8: 0.9: 0.9: 0.8: 0.8: 0.8: 1.0, length to width ratios of antennomeres I–XI 2.8: 1.6: 2.9: 3.4: 3.2: 3.2: 3.4: 3.4: 3.6: 4.0: 5.1. Elytra elongate and parallel-sided, 1.9x longer than wide; disc with dense, coarse punctures, arranged into longitudinal rows, with one distinct longitudinal ridge between two longitudinal rows of punctures. Tarsomeres I of front legs swollen in males; subparallel in females. Aedeagus ( Figs 17 C–17E) extremely slender, 7.8x longer than wide; sides widest at apical 1/10, gradually narrowed towards basal 1/4, abruptly narrowed subapically, apex narrowly rounded, with deep, narrow median notch, from apex to apical 1/7; tectum triangular; ventral surface with deep notch from apical 1/10 to basal 1/3, abruptly widened at apical 1/4; triangular sclerites elongate; internal sac with one median, elongate sclerite, parallel-sided, basally and dorsally covered with one pair of elongate and apically tapering sclerites, large, as long as median sclerite, with two pairs of lateral clusters of stout setae. Gonocoxae ( Fig. 17G ) elongate, widest near apex, both gonocoxae combined together from basal 1/6 to apical 1/13; 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. 17F ) elongate; 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. 17H ) strongly swollen; pump slender and strongly curved; proximal spermathecal duct deeply inserted into receptacle, narrow and short.

Variations. Color patterns of adults of T. fairmairei are extremely variable but distinct in different localities. In addition to yellowish brown bodies and metallic green elytra in Java, specimens from this island have reddish brown bodies and metallic purple elytra ( Figs 16D, 16E ). Some specimens from Nusa Kembangan island have reddish brown bodies and metallic purple elytra as mentioned above but the latter are yellowish brown basally ( Fig. 16F ). Specimens from Borneo have metallic blue or purple bodies, with black antennae except the apical white antennomeres, but antennomeres XI can be apically or entirely darker ( Figs 16G, 16H ). Specimen from Sumatra, where it is sympatric with T. pulchella , have a reddish body and metallic blue elytra, as in T. pulchella , but differ by the apically darkened antennomeres XI ( Fig. 16I ).

Diagnosis. Specimens of T. fairmairei are similar to those of T. pulchella with distinct longitudinal ridges on the elytra, but the former species is restricted to Borneo, Sumatra and Java, ( T. pulchella is distributed in West Malaysia, Thailand, Singapore, and Sumatra), and specimens have narrowly rounded apices of the aedeagi and internal sacs possessing two pairs of clustered setae (long, tubular apices and internal sacs with one pair of clustered setae and one pair of hook-like sclerites in T. pulchella ).

Distribution. Brunei, East Malaysia, Indonesia (Java, Sumatra)
