Solovyev, Alexey V. & Saldaitis, Aidas, 2021, Five new species of Limacodidae (Lepidoptera: Zygaenoidea) from South-East Asia, Zootaxa 4999 (2), pp. 101-116 : 104-105

Sansarea alenae sp. nov.

( Figs 6 , 20 )

Type-material. Holotype: ♂, “ China, NW. Yunnan | Nu Jiang valley | Fugong / Gongshan | H- 1800 m | N 27˚18.24`` | E 98˚53.20`` | 17.v.2018 | Butvila & Saldaitis [leg.] (genital slide № CAS-20-03, WIGJ) . Paratype: 1♂, same data as holotype ( CAFM) .

Description. Male. Forewing length 12.0–13.0 mm ( Fig. 6 ). Antenna shortly unipectinate. Ground color ochre. Forewings with pattern typical of the genus. Hindwings dark greyish brown, with lighter fringe and bright yellow dorsal margin.

Abdomen. Male sternite VIII has a pair of digitiform processes, slightly pointed, with tips bending outwards.

Genitalia. Uncus with lateral expansions (uncus looks like trifid) and apical spur ( Fig. 20 ). Gnathos with two narrow long lateral processes curved at right angle apically, with the left one bearing a weak papilla-shaped medial process ( Fig. 20 , this process is shown by arrow). Valvae elongated, without well-defined sacculus and lacking saccular processes. Juxta flattened, with apical notch. Aedeagus slightly spiraled, narrow and with a strongly sclerotized apical spur.

Female. Unknown.

Diagnosis. The species is similar to its congeners with the exception of Sansarea formosana Solovyev, 2017 known from Taiwan, which is much darker in coloration. The new species differs from its congeners ( Figs 21–24 ) by the gnathos showing two strong lateral lobes curved apically at right angle, with the left one bearing a weak papilla-shaped medial process, and by the processes of sternite VIII digitiform, slightly pointed, and with tips bending outwards.

The male genitalia are mostly similar to those of Sansarea grata Solovyev & Witt, 2009 ( Fig. 22 ) and S. zeta Solovyev & Witt, 2009 ( Fig. 23 ). However, in S. alenae sp. nov., the long lateral processes of the gnathos are curved at a right angle apically, the apical processes of the gnathos are at least 2/3 the length of the lateral ones, and the processes of sternite VIII are more separated and smaller, with the length not exceeded a half distance between these processes.

Distribution. China (Yunnan).

Phenology and habitat. Two males were collected at ultraviolet light in middle May at an altitude of approximately 1,800 m asl in primary mountains mixed forest, dominated by various deciduous trees, bamboo and shrubs ( Figs 34, 35 ).

Etymology. The species is named in honor of Alena Kazakevich (Lida, Belarus), for her deep understanding and support of the entomological activities of the second author.
