Teng, Kaijian & Wang, Shuxia, 2018, Genus Tecmerium Walsingham (Lepidoptera: Blastobasidae) new to China, with descriptions of two new species, Zoological Systematics 43 (4), pp. 420-428 : 425-426

Tecmerium scythrella ( Sinev, 1986) ( Figs 2 , 6 , 10 )

Holcoceroides scythrella Sinev, 1986: 66 . Type locality: Russia.

Sinevina scythrella (Sinev) : Koçak & Kemal, 2007: 6.

Tecmerium scythrella (Sinev) : Sinev, 2008: 83.

Diagnosis. Adult ( Fig. 2 ) forewing length 4.5–6.5 mm (n = 11). Tecmerium scythrella is characterized by the eighth sternum with posterior half sclerotized ( Fig. 10 ), the relatively broader proximal flange, and the two apical processes of the sclerite of the phallus equal in length ( Fig. 6 ). It is similar to T. yunnanense sp. nov. in the male genitalia, and the differences see the diagnosis of T. yunnanense sp. nov.
