IntroductionThe present paper is the second result of our inves-

tigations on Sesiidae of Sulawesi [Gorbunov, Arita,2015] and concerns description of a new species of thegenus Cyanosesia Gorbunov et Arita, 1995. The genusCyanosesia, with type species C. tonkinensis O. Gor-bunov et Arita, 1995, was originally described fromVietnam [Gorbunov, Arita, 1995], and currently it con-tents 15 Asian species [Arita, Gorbunov, 2002; Gor-bunov, Arita, 1995; Gorbunov, Kallies, 1998; Kallies,2003; Kallies, Arita, 2004; Pühringer, Kallies, 2004]. Allof them with the type localities are listed in the Table 1.Thus, the genus seems to be restricted to the OrientalRegion.

All labels of the types are shown in detail. Each labelis separated by quotation marks, and lines in a labelseparated by a «/». The holotype of the new species isdeposited in the collection of Zoological Institute ofthe Russian Academy of Sciences, St Petersburg, Rus-sia (ZISP), paratypes are housed in the author collec-tion (COGM).

Male genitalia (genital preparation OG–013–2014) (Figs10–13). Tegumen-uncus complex well-developed, with notnumerous setae on inner surface ventro-apically; tegumenrelatively long and narrow; gnathos rather well-developed,slightly asymmetrical and rounded distally (Fig. 10); valva(Fig. 11) pentagonal-oval, densely covered with multifurcatescale-like setae in dorsal half and with sparse hairs in ventralhalf; crista sacculi well-developed, triangular-oval, with hair-like setae on anterior margin; saccus (Fig. 12) rounded basal-ly, about as long as vinculum; aedeagus (Fig. 13) about as longas valva, relatively thick; vesica with numerous pointedspinules.

Individual variability. This species varies slightly in thenumber of yellow scales on the thorax, abdomen and forewing (Figs 1–8). Besides that, both males and females aresomewhat variable in individual size. Males: alar expanse18.6–20.5 mm; body length 10.0–11.5 mm; fore wing 8.3–8.5mm; antenna 5.0–5.2 mm. Females: alar expanse 24.0–24.9mm; body length 12.3–12.5 mm; fore wing 10.5–11.0 mm;antenna 5.5–6.0 mm.

Differential diagnosis. Superficially, the female of thisnew species is somewhat similar to that of C. vietnamica O.Gorbunov et Arita, 1995 and C. litseavora Kallies et Arita,2004, but it can be easily distinguished by the conformationof the fore wing (almost completely opaque in the firstspecies compared; cp. Figs 1, 3 with Fig. 4 in [Gorbunov,Arita, 1995]; discal spot orange in the second species com-pared; cp. Figs 1, 3 with Fig. 12 in [Kallies, Arita, 2004]) andby the structure of the female genitalia (corpus bursae with-out signum in C. vietnamica and C. litseavora; cp. Fig. 9 withFig. 18 in [Gorbunov, Arita, 1995] and Fig. 34 in [Kallies,Arita, 2004]). By the coloration of the legs and abdomen andby the conformation of the fore wing, the male of C. lelejisp.n. is clearly distinguishable from all of its congeners.Beside that, this new species differs from other Cyanosesiaspecies by having multifurcate scale-like setae in the dorsalhalf of the inner surface of the valva of the male genitalia anda long and narrow signum in the corpus bursae of the femalegenitalia. It is possible that these characters will allow forcreating a distinct species group or even subgenus within thegenus in the future.
