Yang, Hailin, Cao, Liangming & Cai, Waizhi, 2012, Paralenaeus (Hemiptera: Reduviidae: Reduviinae) found in China with the description of the second species of the genus, Zootaxa 3281, pp. 56-60 : 57-60

Paralemaeus schaeferi , sp. n.

( Figs. 1–14 )

Description. Color. Body black. Eyes and ocelli silvery; antennae (except basal segment), fore and mid tibiae, hind femora brown to dark brown; hind tibiae light brown; oblique irregular spots on basal half of corium, triangular spots on apical part of corium, most of each connexival segment red.

Structure. Body medium-sized, elongate oblong ( Figs. 1 , 2 ). Apical half of second antennal segment, third and fourth antennal segments, fore and mid femora, tibiae, apex of abdomen apex sparsely scattered with long, golden setae; venter of head, thorax and abdomen with short pubescence.

Head. Head oblong, depressed in lateral view, 1.2 times as long as its width and 0.65 times as long as pronotum ( Fig. 1 ). Ocelli large, round, located far from each other. Anteocular portion about twice as long as postocular; dorsal surface of anteocular portion, anterior portion of maxillary plates and posterior portion of mandibular plates strongly swollen, distinctly elevated above vertex; apex of mandibular plates rounded and protruding ( Figs. 1 , 2 ). Postocular portion of vertex with a deep, wide longitudinal depression along midline; transverse constriction anteriad to ocellar area convex forwards. Anterior margin of ocellar area reaching level of posterior margin of eyes. First antennal segment not reaching apex of head, second segment four times as long as first; last two antennal segments nearly of same length. First visible labial segment shorter than second one, both robust, first visible segment not reaching anterior margin of eye; third visible segment elongately triangular, curved ( Fig. 2 ).

Thorax. Pronotum trapezoid, depressed, as long as width between humeral angles ( Fig. 1 ). Collar processes prominent. Anterior pronotal lobe 0.75 times as long as posterior, shallowly and symmetrically sculptured. Humeral angles rounded; posteriad to anterior lobe and whole posterior lobe centrally with a longitudinal sulcus, integument crinkled around this sulcus; posterior lobe also with a pair of longitudinal sulci laterally; all three sulci with transverse ridges. Scutellum center deeply depressed; apical spine horizontal and long ( Fig. 5 ). Fore and mid femora thick, armed with tubercles ventrally forming a series; fossula spongiosa occupying about 1/3 length of tibia ( Figs. 1 , 3 ). Hemelytra distinctly surpassing apex of abdomen.

Abdomen. Elliptic, slightly elongate, venter flat. Parameres club-shaped, curved, with a truncate apophysis subapically ( Figs. 12, 13 ); median process of pygophore short, apex blunt, rounded in ventral view ( Figs. 4, 6, 7 ); basal plate thick ( Fig. 11 ); dorsal phallothecal sclerite heavily sclerotized; struts fused, short, not reaching apex of phallosoma; endosoma with symmetrical sclerotized sclerites ( Figs. 8–10 ).

Measurements. [3 (n=1), in mm] Body length 10.3; maximum width of abdomen 3.8; length of head 1.5; length of anteocular portion 1.1; length of postocular portion 0.4; synthlipsis 0.6; interocellar space 0.35; length of antennal segments I–IV= 0.4, 1.6, 1.5, 1.5; length of visible labial segments I–III=0.7, 0.9, 0.6; length of anterior lobe of pronotum 1.1, length of posterior lobe 1.5; width of pronotum 3.3; length of scutellum 1.5; length of heme- Type material. Holotype, 3, China, Yunnan Province, Xishuangbanna, Yaoqu, 18.V.2011, 1120 m altitude, light trap, Yang Hailin leg.

Remarks. The new species can be easily separated from its congener by the coloration.

Distribution. China (Yunnan).

Etymology. The new species is named in honor of Prof. Carl W. Schaefer of the University of Connecticut, for his great contribution to heteropterology and his kind help in our studies.
