Description.

Length 5.5-6.6 mm, width 2.7-3.4 mm. General color (Fig. 1A-C View Figure 1 ) reddish brown; antennae black; legs dark brown. Antennomeres II-XI filiform but stout in males (Fig. 2A View Figure 2 ), ratios of lengths of antennomeres I-XI 1.0: 0.4: 0.7: 0.9: 0.8: 0.8: 0.8: 0.8: 0.7: 0.7: 0.8; ratios of length to width from antennomeres I-XI 2.5: 1.5: 1.9: 2.7: 2.5: 2.5: 2.5: 2.5: 2.4: 2.4: 3.5; stout antennae in males similar in females (Fig. 2B View Figure 2 ), ratios of lengths of antennomeres I-XI 1.0: 0.4: 0.6: 0.8: 0.8: 0.7: 0.8: 0.7: 0.7: 0.6: 0.8; ratios of length to width from antennomeres I-XI 2.5: 1.5: 2.0: 2.5: 2.4: 2.3: 2.5: 2.4: 2.6: 2.3: 2.9. Pronotum 1.6-1.7 × wider than long; disc with scarce, fine punctures at sides, reduced medially, with transverse groove near base, medially abbreviated, laterally connected with short longitudinal groove on basal margin; lateral margins slightly rounded, widest behind apices; apical margin slightly concave and basal margin slightly convex. Elytra 1.5 × longer than wide; disc with confused, dense, reduced punctures; with one small tubercle behind scutellum; with one distinct longitudinal ridge from humeral calli, parallel with lateral margin, abbreviated subapically; with one additional ridge also from humeral calli, distinct, directed medially; lateral margins moderately rounded, widest at apical third, apices convergent. Aedeagus (Fig. 2C, D View Figure 2 ) extremely slender, 7.5 × longer than wide; parallel-sided, slightly narrowed at apical 1/4, strongly narrowed subapically, apex narrowly rounded; moderately curved at basal 1/3 in lateral view; tectum slender, longitudinal, apex recurved; no endophallic sclerites. Apical margin of abdominal ventrite V in males with distinct, narrow median lobe (Fig. 2G View Figure 2 ), apical margin slightly recurved, with short median internal ridge at middle of basal margin, from basal fourth to base; basal margin normal. Gonocoxae (Fig. 2F View Figure 2 ) longitudinal and connected basally, with narrow furrow between gonocoxae; each gonocoxa narrowed subapically, apex narrowly rounded, with eight long apical setae; base strongly sclerotized and narrow. Ventrite VIII (Fig. 2E View Figure 2 ) in females with apex weakly sclerotized, small, apical margin irregular; with dense short apical setae; spiculum extremely elongate. Spermathecal receptaculum (Fig. 2H View Figure 2 ) swollen, not delimited from pump; pump long and curved, with apical process curved; sclerotized spermathecal duct extremely short, not separated from receptaculum.

Diagnosis.

Adults of J. houjayi sp. nov. are similar to those of J. ruficollis Jiang, 1989 from China (Xizang) with reddish brown bodies, but differ in possessing black antennae and dark brown legs (yellow antenna with one or two apical antennomeres black, and reddish brown legs in J. ruficollis ).

Host plant.

Scutellaria indica L. ( Lamiaceae ).

Biology.

Scutellaria indica is a small herbaceous plant (Fig. 3A View Figure 3 ) growing on slopes along roads (Fig. 3B View Figure 3 ). Adults appear only during May, usually resting on the undersides of leaves during daytime (Fig. 3C, D View Figure 3 ). Adults feed on the leaves (Fig. 3E View Figure 3 ) and were observed mating (Fig. 3F View Figure 3 ) occasionally.
