Macrosiagon armata ( Waterhouse, 1883)

( Figs. 1–2 )

Emenadia armata Waterhouse, 1883: 280 .

Macrosiagon armatum: CSIKI (1913) : 10 (new combination). Type locality: India, Coimbatoor [= India, Tamil Nadu].

Type material examined. LECTOTYPE (by present designation): 1♀ (Figs.. 1–2) ( BMNH), ‘Type / H.T.[rounded white label with red margin] // S. / Ind. [grey round label] // Emenadia / armata / Waterh. [hw, white label] // LECTOTYPE [p, red label] // Emenadia armata / Waterhouse, 1883 / Lectotype / Jan Batelka design. 2010 [p]’.

Additional material examined. INDIA: TAMIL NADU: 1 ex. (antennae are missing) ( BMNH), ‘Coimbatore [hw, round grey label]’. DARJEELING (WEST BENGAL): 1 ♀ ( BMNH), ‘Mungphu [p] // Atkinson / col. / 92-3 [p]’. INDO- NESIA: SUMATRA: 1 J ( JHCP), ‘Indonesia / W. Sumatra / 7.1991 [p]’.

Variability. Male similar to female in coloration, no sexual dichroism observed.

Remarks. WATERHOUSE (1883) placed a male symbol after his description, however in the BMNH only females have been identified including the specimen labeled as a type. He did not state on how many specimens his description was based upon. Since the existence of other syntypes cannot be excluded (e.g. the specimen of unknown sex from the type locality in Additional material examined) I propose to designate a lectotype to stabilize the nomenclature in the group (Article 74.7. and Recommendation 73F of the ICZN 1999).

Distribution. The species seems to be widely distributed in the Oriental Region, reaching also the Palaearctic Region in Darjeeling, but apparently is uncommonly collected. So far known only from the type locality situated in the Tamil Nadu ( India). It is recorded here from Darjeeling district (West Bengal, India) and Sumatra ( Indonesia) for the first time.
