Redescription.

Adults. Length 4.0– 4.4 mm, width 2.8–3.3 mm (n = 59). General color yellowish brown (Fig. 3 D – F View Figure 3 ); elytra, meso- and metathoracic, and abdominal ventrites metallic purple; four basal antennomeres I – IV yellowish brown, V dark brown, VI – XI black. Antennae (Fig. 5 A View Figure 5 ) filiform in males, ratios of lengths of antennomeres I to XI 1.0: 0.6: 0.6: 0.5: 0.6: 0.6: 0.7: 0.7: 0.8: 0.8: 1.1; ratios of length to width from antennomeres I to XI 2.4: 2.0: 2.3: 2.0: 2.2: 2.2: 2.3: 2.3: 2.5: 2.5: 3.5; similar in females, ratios of lengths of antennomeres I to XI (Fig. 5 B View Figure 5 ) 1.0: 0.6: 0.6: 0.5: 0.6: 0.6: 0.7: 0.7: 0.8: 0.7: 1.0; ratios of length to width from antennomeres I to XI 2.5: 2.4: 2.6: 2.5: 2.6: 2.1: 2.6: 2.3: 2.5: 2.4: 3.7. Pronotum 2.0–2.2 × wider than long; disc dull, with micro-reticulation, less convex; with sparse, fine punctures; longitudinal groove on each side of apical margin deep, with several coarse punctures along groove; longitudinal groove on basal margin short and shallow; lateral margins rounded; apical margins slightly concave; basal margin medially convex. Elytra 1.1 × longer than wide; disc with coarse, confused punctures, mixed with fine punctures; lateral margins rounded, narrowed behind middle. Aedeagus (Fig. 5 C – E View Figure 5 ) wide, ~ 3.7 × longer than wide; parallel sided, moderately narrowed at apical 1 / 10; apex truncate, but with one median rounded process; extremely strongly curved in lateral view; tectum membranous. Endophallic spiculae reduced. Gonocoxae (Fig. 5 U View Figure 5 ) longer than wide, and basally connected; apex of each gonocoxa widely rounded, curved inwards, with eight or nine long setae. Ventrite VIII (Fig. 5 F, G View Figure 5 ) well sclerotized, 2–4 pairs of setae arranged into transverse line along sides of apical margin, spiculum extremely long. Spermathecal receptaculum (Fig. 5 H View Figure 5 ) strongly swollen; pump long and curved, with long apical process; spermathecal duct sclerotized, moderately long after base of spermathecal gland.

Diagnosis.

Adults of Nisotra dohertyi are characterized by the confused punctures on the elytra (punctures arranged into paired longitudinal lines in other species), dull pronotum with micro-reticulation (shining pronota without micro-reticulation in others), and ovate elytra, 1.1 × longer than wide (oblong elytra, 1.2 × longer than wide in others), although this character is similar in a few adults of N. chrysomeloides and N. gemella with more ovate bodies. In males of N. dohertyi , the truncate apex and small process of the aedeagus (Fig. 5 C View Figure 5 ) differ from the acute apex in N. chrysomeloides (Fig. 4 C View Figure 4 ) and widely rounded apex and small medial process in N. nigripes (Fig. 14 C View Figure 14 ). The strongly curved aedeagus in lateral view (Fig. 5 E View Figure 5 ) differs from the moderately curved aedeagus in N. chrysomeloides (Fig. 4 E View Figure 4 ) and N. gemella (Fig. 7 D View Figure 7 ), and slightly curved aedeagus in N. nigripes (Fig. 14 D View Figure 14 ). The membranous tectum (Fig. 5 C View Figure 5 ) differs from the sclerotized tectum in N. chrysomeloides (Fig. 4 C View Figure 4 ). In females of N. dohertyi , the inwardly directed apices of the gonocoxae differ from the straight gonocoxae in N. gemella (Fig. 7 G View Figure 7 ), dorsally directed apices in N. chrysomeloides (Fig. 4 H View Figure 4 ), and laterally directed apices in N. nigripes (Fig. 14 G View Figure 14 ). Abdominal ventrite VIII with several pairs of long setae along apical margin (Fig. 5 F, G View Figure 5 ) differs from the presence of one transverse line of long setae inside the apical margin and dense short setae along the apical margin in others (Figs 4 F View Figure 4 , 7 E View Figure 7 , 14 E View Figure 14 ).
