Panzeria rufitibialis sp. nov.

( Figs 43–44 , 65–68 , 80–81 )

Diagnosis. Medium to small-sized species. This species resembles P. inusta , but is usually smaller in size and has apical portion of scutellum, anterolateral portion of 3rd and 4th abdominal tergites, and tibiae reddish. The presutural acrostichal setae and the median marginal setae of abdominal syntergite 1+2 are usually absent as opposed to the one pair of acrostichal setae and median marginal setae present in P. inusta .

Description. Body length: 7.6–11.1 mm.

Male. Head with grayish-white pruinosity on fronto-orbital plate, parafacial, genal dilation and occiput, reflecting silvery white on lower fronto-orbital plate and parafacial under certain directions of light; lower portion of parafacial, anterior triangular portion of gena and face with thin whitish pruinosity; antenna black, pedicel sometimes broadly reddish yellow; palpus reddish yellow, darkened basally. Frons at narrowest point 0.12–0.16 of head width; face about 0.6 times as long as frons in profile; inner vertical setae crossing, about 2/3 of eye height; 10–12 frontal setae, upper ones fine, lowest seta slightly below level of middle of pedicel, sometimes an irregular row of 3–5 setae present outside row of frontal setae near antennal base; parafacial bare, wide, nearly parallel-sided, about 1.3 times as wide as postpedicel in its horizontal position; gena about 1/2 of eye height in horizontal position; occiput bulged, with 1–2 rows of short black hairs behind row of postorbital setae. Antenna falling short of lower margin of face by about 2/3 length of pedicel; postpedicel about 1.5 times as long as pedicel; arista thickened on basal 1/2; 2nd aristomere at most 2 times as long as wide. Proboscis short; prementum about 4 times as long as wide; palpus subequal in length to pedicel and postpedicel together.

Thorax black in ground color, apical 1/2–1/3 of scutellum reddish brown, with thin whitish gray pruinosity; 3 broad longitudinal vittae visible, weak and diffusing marginally on postsutural scutum. Zero presutural and three postsutural acrostichal setae; 3 presutural and 3 postsutural dorsocentral setae; 0 presutural and 3 postsutural intraalar setae; 4–5 supra-alar setae, if 4 setae present, then 2nd seta shorter than others, and if 5 setae then 2nd and 4th setae short; 3 katepisternal setae; anepimeral seta almost reaching level of posterior 1/2 of lower calypter; anatergite bare; scutellum with 4 pairs of long marginal and 1–2 pairs of short and suberect discal setae; apical scutellar setae absent; distance between bases of subapical scutellar setae 1/2–2/3 of that between basal and subapical setae. Wing hyaline; lower calypter pale yellowish white; relative lengths of 2nd, 3rd and 4th costal sectors approximately as 3:6:2.5; length of vein M from dm-cu crossvein to bend about 1.5 times distance between bend and wing margin. Legs black, tibiae reddish yellow, darkened basally especially on ventral side; pulvilli dull yellowish; fore tibia with 2 preapical dorsal setae, a row of anterodorsal and 2–3 posterior setae; mid tibia with 2–3 anterodorsal, 3–4 posterodorsal and 1–2 ventral setae, if 2 then lower seta fine; hind tibia with 4–5 anterodorsal, 4 posterodorsal and 3 ventral setae.

Abdomen black, anterolateral portions of 3rd and 4th tergites reddish yellow, with thin whitish pruinosity on anterior 1/3 of 3rd tergite, 1/2 of 4th tergite and entire 5th tergite, pruinosity diffusing and very thin on median and posterior portions of 3rd and 4th tergites. Hairs on dorsum rather dense, long and erect; syntergite 1+2 without median marginal setae, with 1–2 lateral marginal setae; 3rd tergite with 2 pairs or 5 strong median discal, 1–2 lateral discal, 2 median marginal and 2–3 lateral marginal setae, median discal setae rather irregularly set; 4th tergite with 1–2 pairs of strong median discal and a row of marginal setae, discal setae sometimes irregularly set; 5th tergite with a rather irregularly-set row of strong discal setae and a row of rather strong marginal setae; 2nd to 4th sternites exposed, with dense, rather long suberect hairs.

Terminalia: 6th tergite about 1/4 as long as syntergosternite 7+8, with a row of long fine setae mixed with several fine hairs, with thin grayish pruinosity; syntergosternite 7+8 and epandrium with very thin grayish pruinosity; cerci in dorsal view narrowed from base to basal 4/7, then slightly widened medially and weakly narrowed to apex, apical portion about 1/2 as wide as widest basal portion, strongly ridged on both sides of basal 2/7 to 4/7, in lateral view apical portion nearly straight or even weakly directed upward; surstylus with strong triangular ridge on basal 1/3, with 4–5 short spines near apex; postgonite widened apically with rounded excavation on posterior margin.

Female. Differs from male as follows: frons wide, 0.25–0.27 of head width at vertex; frontal vitta wide, weakly widened anteriorly, about 2/3 as wide as fronto-orbital plate; outer vertical seta developed, about 2/4 as long as inner vertical seta; ocellar setae about 1/2 as long as outer vertical seta; 2 outwardly-directed prevertical setae, anterior seta stronger than posterior seta and about as long as outer vertical seta; 1 proclinate orbital seta subequal in length to prevertical seta; 7–8 frontal setae; antenna with scape and pedicel orange yellow; palpus entirely reddish yellow; legs with claws and pulvilli shorter than 5th tarsomere; 3rd and 4th abdominal tergites each usually with a pair of median discal setae. Terminalia: 6th tergite short, entire, with a row of strong setae marginally; 6th sternite subequal in length to 7th sternite; 7th tergite entire, nearly quadrate in profile, with a row of rather short setae marginally; 7th sternite with a pair of small projections on posteromedian margin in ventral view; 8th tergite consisting of small and rather high hemitergites; epiproct absent; hypoproct rather long, ventromedian portion rather broadly membranous.

Etymology. The specific name is taken from the reddish tibiae of this species, from the Latin adjective rufus (red) plus the noun tibia (leg) and the adjectival suffix ilis (having the nature of).
