Camptoptera serenellae Viggiani, 1978 , stat. rev.

( Figs 22–27 )

Camptoptera serenellae Viggiani 1978: 151 –152. Type locality: Hakgala (1800 m, above Hakgala Botanical Garden), Nuwara Eliya District, Central Province, Sri Lanka.

Camptoptera serenellae Viggiani : Huber & Lin 1999: 31 (list).

Stephanocampta serenellae (Viggiani) : Triapitsyn 2014: 9 (incorrect generic transfer based on male paratype from Sri Lanka).

Type material examined. Holotype male [ MHNG] on slide ( Fig. 22 ) labeled: 1. “ Camptoptera ♂ serenellae Vigg. Holotype [underlined in red ink] G. Viggiani – 1977”; 2. “ CEYLAN, Hakgala 28.I.70 30C Tamisages dans la forêt vierge au-dessus du jardin botanique à 1800 m. leg. Cl. Besuchet et I. Löbl”. The holotype ( Fig. 23 ) is in fair to poor condition, complete, mounted dorsoventrally in a darkened mountant, with the wings partially obscured.

Redescription. MALE (holotype). General color of body and appendages dark brown except scape, pedicel (less so), and some leg segments yellowish-brown. Sculpture on head and mesosoma likely at least partially reticulate, as described and illustrated in original description (now very difficult to observe on specimen); occiput transversely striate. Antenna ( Fig. 24 ) with flagellum 10-segmented, only F2 ring-like; scape smooth, 4.2× as long as wide. Mesosoma much longer than gaster ( Figs 26, 27 ); propodeum with almost parallel, complete submedian carinae widely separated from each other. Fore wing ( Fig. 25 ) rather wide for Camptoptera (8.8× as long as wide); longest marginal seta about 3.7× maximum wing width; disc with about 3 rows of rather long setae beyond apex of venation besides admarginal rows of setae. Petiole strongly ridged transversely, about 1.2× as long as wide. Genitalia (hardly visible in holotype) seem to be typical for Camptoptera .

Measurements of holotype (as length or length:width). Body, 455; head, 110; mesosoma, 234; gaster, 115. Antenna: scape (including radicle), 76; pedicel, 39; F1, 36; F2, 4; F3, 42; F4, 42; F5, 42; F6, 42; F7, 40; F8, 42; F9, 42; F10, 51. Fore wing, 503: 57; longest marginal seta, 209.

Remarks. Triapitsyn (2014) transferred this species to Stephanocampta based on examination of the male paratype, but that nomenclatural action has proven to be unjustified based on more recent examination of the holotype of C. serenellae by the same author. The holotype male is correctly classified in Camptoptera ; hence its reinstatement here in the original genus. The paratype belongs to an unidentified species of Stephanocampta and is not considered in this review pending further examination and much needed matching with a conspecific female. The latter also applies to the holotype of C. serenellae , which belongs to a species very similar in many regards to C. matcheta Subba Rao from India, particularly the wide fore wing and the ridged petiole. Further investigations are needed on both taxa, which possibly may differ in the sculpture of the head and mesosoma. The third author of this communication has seen several similar, but all apparently different, species from this little known group from other countries in the Oriental region. The male of C. serenellae has an unusual flagellum in having only F2 ringlike, like in the species of the former genus Eomymar Perkins , now a synonym of Camptoptera ( Huber & Lin 1999; Triapitsyn 2014), although its other flagellar segments seem to be relatively shorter than in the unidentified species of Eomymar from Thailand illustrated by Triapitsyn (2014). However, based on other features, including the fore wing, C. serenellae is definitely not a member of the group of species formerly assigned to Eomymar .
