Spin bamboo borer (Bambusiphaga caudospina), later bamboo borer (Bambusiphaga laterospina) and stripe bamboo borer (Bambusiphaga striola)

NEWS - Spin bamboo borer (Bambusiphaga caudospina Lv, Li & Chen, sp. nov.), later bamboo borer (Bambusiphaga laterospina Lv, Li & Chen, sp. nov.) and stripe bamboo borer (Bambusiphaga striola Lv, Li & Chen, sp. nov.) from Southwest China increased the total number in the genus to 34 species.

Bambusiphaga Huang & Ding 1979 was assigned to 6 species: Neosinocalamus affinis (Rendle) and Phyllostachys sp. (Poales, Poaceae) with B. nigropunctata Huang & Ding 1979 as the type species from Sichuan Province, China. To date 31 species have been recorded in China (28 species), Singapore (2 species), Malaysia (2 species), others in the Philippines, India and Eastern Himalayas (1 species each).

B. caudospina has a light vertex, without dark brown spots; lateral areas of pronotum with dark brown markings; mesonotum with dark brown markings; forewings with one large black marking at basal 1/3; medioventral process of pygofer forked near apical 1/2; dorsolateral margin of aedeagus with three spinous processes at apical part, ventrolateral margin with four spinous processes of similar length.

This species is similar to B. maculata Chen & Li 2000, but differs in that forewings MP1+2 are completely blended (vs. blended at the base in B. maculata); apical part of genital peduncle unbranched (vs. branched); and apical part of aedeagus with several spinous processes on both sides (vs. only on one side).

B. laterospina has vertex light, without dark brown spots; lateral areas of pronotum with dark brown markings; mesonotum with dark brown markings; forewings with basal ⅓ black; pygofer with long medioventral and lateroventral processes; inner margin of genital styles with a toothed process at middle part; apical part of aedeagus with two slender spinous processes.

This species is similar to B. taibaishana Qin 2012, but differs in the outer tegula being black-brown, the inner part being yellowish-white (vs. black-brown tegula in B. taibaishana); pygofer with a pair of long medioventral processes and one lateroventral process (vs. short, without lateroventral processes); and the inner margin of genital peduncle with a toothed process at middle part (vs. without process at middle part).

B. striola has a brownish-black vertex, the basal compartment milky-white; tegula milky-white; forewings with a dark brown longitudinal band from anterior margin of basal part to posterior margin of apical part along the CuP and MP; pygofer with a pair of medioventral processes; anal segment with the process distinctly divided into 3 processes at apex; apical part of aedeagus with two unciform processes, basal and middle parts each with a dentate processes.

This species is similar to B. pianmaensis Chen & Liang, 2007, but differs in that the posterior edge of the pronotum is milky white in the middle (vs. blackish brown in B. pianmaensis); the apical part of the anal segment is divided into 3 processes at the apex (vs. 2); and the basal and middle parts of the aedeagus each with a dentate process (vs. without dentate process).
