Beaver, Roger A., 2018, A review of the genus Baiocis Browne, 1962 (Coleoptera: Curculionidae: Platypodinae), with new species, new synonymy and a key to males, Zootaxa 4434 (3), pp. 481-501 : 493-494

Baiocis angustipennis (Schedl)

( Figs 24‒25 )

Platypus angustipennis Schedl, 1942: 203 .

Baiocis angustipennis (Schedl) : Browne 1962: 651.

Taxonomy: This species was described by Schedl (1942) in Platypus without any clear indication of the sex of the specimens, although he compared them with the female of Platypus perinimicus Schedl. In his catalogue of his type collection, Schedl (1978) designated a male lectotype, and this is cited by Wood and Bright (1992). The senior author has examined this specimen (NMW). It is female, not male. It is placed in Baiocis on the basis of a combination of characters including: the extremely elongate form; the prominent head wider than the pronotum; 3- segmented labial papi; the lack of pronotal mycangia; the femoral grooves more strongly angulate at their anterior end; the protibia transversely carinate on the anterior surface. The male of the species has not been described. A damaged male under this name in NMW, but bearing no determination label, may or may not belong to the species.

New Records: MALAYSIA, Sabah, Sipitang, Mendolong , 25.iv.1988 (S.Adebratt) (1 female); as previous except : 17.iii.1989 (1 female). The specimens have been compared with the lectotype (NMW).

Distribution: East Malaysia (Sabah) and West Malaysia.

Biology: The only host tree recorded is Xylopia cordata (Annonaceae) ( Schedl 1942).
