Parey, Sajad H., Morse, John C. & Pandher, Manpreet S., 2016, Three new species of the genus Lepidostoma Rambur (Lepidostomatidae: Trichoptera) from India, Zootaxa 4136 (1), pp. 181-187 : 182-186

Lepidostoma sainii sp.nov.

( Figs. 7–12 )

Male: Scapes each 1 mm, with single, cylindrical subbasodorsal process at its base, 2.5 times as long as head ( Fig. 11 ). Maxillary palpi each 0.95 mm, 2-segmented; first segment longer than second, straight and cylindrical; second segment curved downward and bearing long setae on its surface ( Fig. 11 ). Average length of each forewing 5.76 mm (n = 13). Wing covered with mixed short setae and scales, anal groove with 1 pseudocell ( Fig. 12 ).

Genitalia ( Figs. 7–10 ): Segment IX narrowly triangular in dorsal view ( Fig. 7 ). Segment X simple, divided into 2 plates closely appressed along midline without excision in dorsal view ( Fig. 7 ); in lateral view broad near base and slightly upturned and round apically ( Fig. 9 ). Inferior appendages each broad near base, apically triangular with concave subapicolateral surface; basodorsal process prominent, short and cylindrical in lateral view ( Fig. 9 ). Phallus truncate and dilated basally; phallicata cylindrical and apically round; parameres about two-thirds as long as phallus and appressed for most of their length.

Etymology. The species is named in honor of Dr. Malkiat Singh Saini for his contributions to Indian caddisfly taxonomy.

Diagnosis. This species resembles Lepidostoma inconspicuum ( Mosely 1941) , but differs in that segment IX is triangular in dorsal view, segment X processes are closely appressed along the midline, and inferior appendages are pointed apically and each has a basodorsal process ( Figs. 7–9 ).
