Wang, Zhaohong, Li, Yajin, Tong, Xiaoli & Mound, Laurence, 2020, Phylogenetic analysis of the Taeniothrips genus-group, with revision of the species of Ctenothrips and Vulgatothrips (Thysanoptera, Thripinae), Zootaxa 4750 (3), pp. 301-327 : 313-315

Ctenothrips parisae sp.n.

( Figs 4 , 19, 23, 30 , 45, 48 , 61–63 )

Female macroptera. Body dark brown including legs, bases of femora and tibiae pale, tarsi pale; antennal segments I–II dark brown, III–V and the basal third of VI yellow, apex of VI and VII brown, VIII yellow; fore wings pale brown with basal fifth paler and sub-base darker. Head longer than wide ( Fig. 4 ), with distinctly elongate reticulations behind eyes; ocellar setae III arising between posterior ocelli, as long as length of eyes; postocular setae 4 pairs arising almost in a row, with pair III slightly ahead row, all these setae shorter than ocellar setae III. Antennae 8-segmented, typical of the genus. Pronotum wider than long, without obvious sculpture, 0–3 pairs of discal setae present medially, 2 pairs of long posteroangular setae, posterior margin generally with 1 pair of setae ( Fig. 19 ). Fore wing first setal row almost complete, setae closely spaced in sub-basal area, but more widely spaced in distal half; first vein with 26–30 setae, second vein with 21–25 setae, clavus with 5+1 setae ( Fig. 30 ). Abdominal tergite I fully reticulate with median setae short, campaniform sensilla close to posterior margin; tergites II–VII almost fully polygonally reticulate, but area close to posterior margin almost smooth; tergite VIII reticulate anteriorly and later- ally, posteromarginal comb complete, a few microtrichia present in front of spiracle; tergite IX with no reticulation; tergite X with weak reticulation, median longitudinal split complete. Abdominal sternites fully reticulate, sternite VII posteromarginal setae S1 and S2 arising in front of margin, with S1 further apart.

Measurements (holotype female in microns). Distended body length 2830. Head length 245, width across eyes 189, ocellar III length 106. Pronotum length 208, width 304; posteroangular setae length, inner 126, outer 126. Metanotum median setae length 70. Fore wings 1720. Antennal length 260; segments III–VIII length 102, 94, 76, 100, 14, 20.

Male macroptera. Similar to female, abdominal tergite VIII with posteromarginal comb complete; tergite IX with two pairs of short stout setae ( Fig. 48 ), anterior pair longer than posterior pair; sternites III–VIII each with a transverse pore plate, about 85–115 microns wide and 30 microns long ( Fig. 45 ).

Measurements (paratype male in microns). Distended body length 2570. Head length 245, width across eyes 203; ocellar setae III length 119. Pronotum median length 301, width 210; posteroangular inner setae 92, outer 86. Metascutum median setae length 38. Fore wings 1340. Antennal segments III to VII length as followings: 76, 72, 54, 84, 14, 22.

Material studied. Holotype female, CHINA, Yunnan, Lijiang (26º51’ N, 100º13’E), from leaves of Paris yunnanensis ( Fig. 63 ), 25.ix.2017 (Huang Hua) . Paratypes: 22 females and 4 males, collected with holotype. Type specimens are deposited in YAU , 1 female and 1 male paratype in ANIC .

Etymology. The species is named after the plant on which it was collected.

Comments: This species is closely similar to kwanzanensis in body structure and color but differs in having a larger body size, about 2.8 mm long, pronotum generally with one pair of posteromarginal setae and male tergite IX with two pairs of short stout thorn-like setae. In contrast, the females of kwanzanensis are about 1.9–2.3 mm long; pronotum generally with two pairs of posteromarginal setae and male without thorn like setae on tergite IX. The male of this species is also similar to transeolineae in having thorn-like setae on tergite IX. It can be distinguished from that species by the 4 pairs of postocular setae arising almost in a row, ocellar setae pair III arising within the ocellar triangle and the pronotum is rather smooth ( Fig. 19 ).
