Hypothenemus birmanus (Eichhoff)

Triarmocerus birmanus Eichhoff, 1878: 384 .

Hypothenemus birmanus (Eichhoff) : Browne 1968: 112.

Hypothenemus maculicollis Sharp, 1879: 101 . Synonymy: Browne 1970: 556.

Schedl (1951a) reported this species as Stephanoderes maculicollis Sharp from Tutuila (Matafao trail). This species was very abundant at all trapping locations. There is an unusual level of morphological variation observed in this species in the samples from American Samoa, some of which are smaller, stouter, and with shorter declivital interstrial bristles, and small granules on declivital interstrial punctures. These may correspond to S tephanoderes maculicollis , but no clear delimitation of this as a separate species was evident.

Schedl (1951a) also listed Hypothenemus multipunctatus (Schedl) as being present in American Samoa, based on two specimens deposited in the Bishop Museum, Hawaii, labeled “Utulei, Tutuila, Samoa, viii– 24–40, 600 ft, beating dead branches” and “Apia, vii–6–40, Upolu, Samoa, at light, EC Zimmerman”. Both of these records are from misidentified specimens, and are in fact H. birmanus .
