Saini, Malkiat S., Pandher, Manpreet S. & Parey, Sajad H., 2013, Two new species of genus Apsilochorema Ulmer (Trichoptera: Hydrobiosidae) from India, Zootaxa 3664 (2), pp. 226-232 : 228-231

Apsilochorema (Archichorema) kashmirensis sp. nov.

( Figs. 1–5 )

Diagnosis. This new species is similar to A. natibhinnam Schmid 1970 , but can be distinguished from it as follows: in A. kashmirensis sp. nov. the apical lobes of the proctiger are narrower than its base, but in A. natibhinnam the breadth of the proctiger is the same throughout. The filipods are curved downward apically in A. natibhinnam and with thick setae only apically, but in A. kashmirensis they are straight and with long setae dorsally and ventrally. The mesal surface of each inferior appendage has thick spines in A. natibhinnam , but in A. kashmirensis these spines are absent. The apical segment of each inferior appendage is without any cleft in A. kashmirensis , but in A. natibhinnam it is with a cleft. The apical segment of each inferior appendage is situated in the middle of the basal segment and is small, not extending downward beyond the basal segment of each inferior appendage; however, in A. kashmirensis the apical segment is situated at 2/3rds of the total length of the basal segment and extends downward beyond the basal segment of each inferior appendage.

Male: Length of each forewing 8.73 mm (n=1) and of each antenna 6.79 mm (n=1). Color of body in alcohol pale brown. Abdominal sternite VII process triangular ( Figs. 3, 4 ) Genitalia ( Figs. 1–2 ): Proctiger shorter than inferior appendages, with membranous, setose apical lobes curved downward apically. Filipods shorter than proctiger. Apex of basal segment of each inferior appendage half as thick as its base, mesal surface with thick setae; apical segment curved downward. Base of phallus narrow and rounded.

Female: Length of each forewing 8.5–9.0 mm (n=3) and of each antenna 6.0–7.0 mm (n=3). Abdomen terminating with slight concavity and ventrally with rounded lobe. In lateral view, tergite VIII subrectangular in shape, with long and stout setae; sternite VIII triangular ( Fig. 5 ).

Etymology: The species is named for the state “Kashmir” from where the type was collected.

Material examined: Holotype 3; INDIA: Jammu & Kashmir, Baderwah, 2400 m, 25.vii.2008, Collectors Parey & Pandher. Paratypes: Same data as holotype, 3Ƥ.

Apsilochorema (Archichorema) meyi sp. nov. ( Figs. 6–10 )

Diagnosis: This species also is close to A. natibhinnam Schmid 1970 but can be distinguished from it because the filipods are clavate in lateral view in A. meyi sp. nov., but in A. natibhinnam the overall thickness of the filipods is the same. The apex of the proctiger in lateral view in A. natibhinnam is also of the same breadth throughout, but in A. meyi the apex is narrower than the base. The mesal surface of the basal segment of each inferior appendage has stout spines in A. natibhinnam , but these spines are absent in A. meyi . The apical segment of each inferior appendage has a cleft in A. natibhinnam , but in A. meyi there is no cleft. The filipods have thick setae only apically in A. natibhinnam , but in A. meyi such setae are all over the filipods. In dorsal view, the apex of each filipod is without any indentation in A. natibhinnam , but in A. meyi the apex of each filipod has an indentation. In dorsal view, the proctiger has a deep apical notch in A. natibhinnam , but in A. meyi the proctiger has only a shallow apical indentation.

Male: Length of each forewing 8.0–8.5 mm (n=5) and of each antenna 5.5–6.0 mm (n=5). Color of body in alcohol brown. Abdominal sternite VII process rounded apically in lateral view ( Fig. 8 ), but truncate in ventral view ( Fig. 9 ). Genitalia ( Figs. 6–7 ): Filipods each narrow at middle and broader at base and apex. Preanal appendages short. Basal segment of each inferior appendage tapering towards apex, rounded apically; apical segment of each inferior appendage small and curved.

Female: Length of each forewing 8.7 mm (n=1) and of each antenna 5.8 mm (n=1). Abdomen terminating with long, digitiform process; ventrally with long and rounded lobe. Tergite VIII with long setae and sternite VIII with posterior margin narrower than its anterior margin ( Fig. 10 ).

Etymology: The species is named in honor of Dr. Wolfram Mey of Germany in recognition of his work on taxonomy and phylogeny of the genus Apsilochorema .

Material examined: Holotype 3; INDIA: Himachal Pradesh, Holi, 1700 m, 16.ix.2008, Collectors Parey & Pandher. Paratypes: Same data as holotype, 33, 1Ƥ; Sikkim: Ravengla, 2000 m, 06.v.2009, Collectors Parey & Pandher, 13.
