Remarks. Although Hewitt (1938) provided formal descriptions of both A. m. lineicauda and A. m. orientalis, he had used both names, with illustrations, descriptions and localities, in an early popular publication (Hewitt 1937b) and these therefore constitute the original type descriptions of both taxa. The subsequent allocation of the names to Hewitt (1938) by (e.g.) FitzSimons (1943) and Welch (1982) is incorrect. However, due to its popular nature the original description (Hewitt 1937b) does not designate a type or type series for either name. The subsequent descriptions (Hewitt 1938) do, however, give insight into the material on which Hewitt must have based his decisions. He lists (p. 39) only “A series of specimens from Dunbrody, Uitenhage district, C.P. collected by Rev. K. Tasman.

The type bottle received from the AMG contained 10 specimens collected at Dunbrody. Eight of them (all labeled AMG 7053) have only ‘Dunbrody’ written on the original label, one (AMG 5193) has ‘Dunbrody’, the collector ‘Rev. K. Tasman’ and date ‘ 5 December 1925 ’ written on it, one (AMG 718B) with another re-written label with Dunbrody and the date ‘ 23/xii/08 ’, and one (AMG 7087) has only ‘Dunbrody’ on the label. The type bottle also contained specimens from: Farm Middleton, Lower Governors Kop near Grahamstown, and Redhouse. The above material is listed in the type description, but the material from Uniondale and Port Elizabeth listed in the type description is unaccounted for in the PEM collection. In their discussion of the taxon, Broadley & Greer (1969: 23) noted four specimens from Dunbrody “AM. 718b, 5193, 7053 (seven, including lectotype of lineicauda, here nominated), and 7087’. This is confusing as AMG 7053 is represented by eight specimens (seven adults and one juvenile ~ see above). They further only indicated that one of the specimens in the series AMG 7053 is the lectotype. One of the specimens from the series AMG 7053 (PEM R5128) bears a label (“ lectotype, 16 March 1968) in D.G. Broadley’s handwriting and we follow this designation. It is very unusual that the Middleton specimen is illustrated in Plate III, Fig. 1, and not one of the numerous specimens from Dunbrody. All specimens, except for PEM R5123 and R5129, have a mid-ventral incision.

Broadley & Greer (1969) considered A. meleagris lineicauda Hewitt, 1937 to be a junior subjective synonym of A. m. orientalis Hewitt, 1937, but the taxon was subsequently elevated to species status (Lamb et al. 2010).
