Plectrocnemia huangi Zhong, Yang & Morse , sp. nov.
( Fig. 2 View FIGURE 2 )
Adult. Length of each male forewing 4.5–6.4 mm (N = 6). Head of specimens in alcohol light brown with yellowish antennae, pronotum dark yellow, meso- and metanota light brown, forewings dark yellow.
Male genitalia. Sternum IX, obtuse triangle anteriorly, much taller than its length in lateral view ( Fig. 2 View FIGURE 2 B); in ventral view ( Fig. 2 View FIGURE 2 A), anterior margin deeply excised in “V” shape, rounded posterior excision shallow and smooth, without mesal protrusion; tergum IX elliptical in lateral view, very lightly sclerotized, almost membranous dorsally. Tergum X lightly sclerotized, long and deep, somewhat roof-like, with truncate apex narrowly and shallowly incised apicomesally in dorsal view ( Fig. 2 View FIGURE 2 C). Intermediate appendages absent. Preanal appendages about 2 times as long as broad, each with blunt apex, without mesoventral process. Inferior appendages nearly quadrate, approximately as long as tall, each with subapicodorsal notch on its distal margin in lateral view ( Fig. 2 View FIGURE 2 B); in ventral view ( Fig. 2 View FIGURE 2 A), apex of ventromesal process of each appendage round, densely covered with fine teeth; digitate process of mesal plate long, extending beyond its appendage, with capitate apex covered with fine teeth and curved downward; in caudal view ( Fig. 2 View FIGURE 2 F), apical setae of mesal plate 6–8 in row. Phallus long, tubular; phallobase half as long as phallicata; pair of parameres long, slender, needle-like, evenly downcurved, at least twice as long as phallobase; phallic sclerites composed of 2 flat spines appressed against each other at their 2 ends in ventral view ( Fig. 2 View FIGURE 2 E); in lateral view ( Fig. 2 View FIGURE 2 D), each with distal half curved ventrad and narrowing to acute, upturned apex; subphallic sclerite present, somewhat trapezoidal in ventral view ( Fig. 2 View FIGURE 2 E), with laterodistal ends strongly produced and curved ventrad.
This new species is very similar to P. jonam (Malicky 1993) from China (Si-chuan). The male differs from that of P. jonam in the following characters: 1) the preanal appendages are each without a mesoventral process (with a mesoventral process curved dorsad in P. jonam ); 2) a phallic sclerite is well developed in 2 flat spines appressed against each other at its 2 ends in ventral view (absent in P. jonam ); 3) the digitate process of each mesal plate has its apex curved downward and the mesal plate has a row of 6–8 setae subapically (the digitate process of each mesal plate has a capitate apex that is not curved downward and has only 2 subapical setae in P. jonam ); and 4) the preanal appendages are about 2 times as long as broad in lateral view (about as long as wide in P. jonam ).
