Differential diagnosis

Elmomorphus curvipes sp. nov. ( Fig. 72 ) belongs to the group of species characterised by having the dorsal plastron distributed on the anterior portions of the head and the posterolateral portions of the elytra. Elytral punctures are scattered over the entire surface and striae are absent. Males bear conspicuous long erect setae or setal clusters on the labrum, prosternal process, and metaventrite. Males have the disc of the metaventrite strongly depressed, and their metatibia possesses a conspicuous tooth near the middle. Elmomorphus curvipes most closely resembles E. dentipes sp. nov. and E. similis sp. nov.; from both it can be distinguished by the strongly curved male metatibia and by the mesotibia being enlarged in the posterior half ( Fig. 72 ). Furthermore, from E. similis it can be separated by the acute parameral apices ( Fig. 73 ). Females can be distinguished from those of E. dentipes , E. similis , and E. simplipes sp. nov. by the spines of the bursa copulatrix being arranged in a distinct dorsal row (spines absent laterally) ( Fig. 74C ). The body is more convex than in E. similis and E. dentipes .

Etymology

The epithet, an adjective (nominative singular), is a combination of the Latin words ‘curvus’ (‘curved’) and ‘pes’ (‘foot, leg’). It refers to the strongly curved male meso- and metatibiae.

Elytra oval, convex, widest close before middle; EL/EW: ♂♂ 1.33–1.56 (1.46 ±0.04, n=66); ♀♀ 1.39–1.53 (1.46 ±0.03, n=27); surface with very fine microreticulation formed by polygonal meshes; punctures scattered; plastron present on epipleura and on apicolateral portions. Protibia slightly curved; mesotibia in males rather strongly curved and distinctly expanded in distal half, in females slightly curved and slightly expanded; metatibia in males distinctly curved with small tooth behind middle, in females slightly curved, teeth absent; PrTL/PL: ♂♂ 0.90–1.18 (1.07 ±0.05, n=66), ♀♀ 0.69–1.09 (1.00± 0.08, n=27). Protarsus 0.75× as long as protibia; terminal protarsomeres as long as three preceding tarsomeres combined.

Ventrites covered with plastron, except middle of ventrites 1–2. Ventrite 5 in males with apex broadly truncate, slightly emarginate or slightly rounded; in females rounded, with small triangular excision; short longitudinal keel present before apex in both sexes. Aedeagus ( Fig. 73 ): phallobase robust, moderately bent ventrad, expanded proximally, PhL/PrL: 1.49–1.89 (1.71 ± 0.07, n= 66); parameres regularly narrowed apically, moderately curved ventrad, apices acute in lateral aspect; penis narrowly rounded apically in dorsal aspect, slightly expanded and rounded in lateral aspect. Ovipositor: valvifers long, flattened, 1.70–2.20 × as long as right coxite; coxites asymmetrical, right one ca. 1.35 × as long as left one. Bursa copulatrix ( Fig. 74C ) with sclerotised spines arranged in a distinct dorsal row; spines on lateral portions absent.

Secondary sexual dimorphism

Males: meso- and metatibiae strongly curved, metatibia with a tooth; labrum, lateral portions of prosternal process, and median part of metaventrite with groups of long setae; median part of metaventrite depressed. Females: median part of metaventrite slightly convex; ventrite 5 with small triangular apical excision.
