Type locality and distribution. Australia: New South Wales (Narrabeen, Sydney). Examined material. Holotype ♀ Label transcription: "Australian Museum, K 359228; Sydney, Narrabeen, 21.7.23, Health Dept.; HOLOTYPE , L. parva pallipes Mall.; Probable type of Apotropina pallipes ; in Mall. Colln.

This dark brown species with yellowish legs was described as a variety of A. parva , based on a single female specimen from the type locality as the latter (Malloch, 1940), where he noted differences from A. parva in having legs entirely 'honey-yellow' , the gena being more narrowed anteriorly (Fig. 17A, B ), but "having only one specimen of each form available I do not care to go farther into details". It was subsequently upgraded to species level (Sabrosky, 1989). The authors have also noted that A. pallipes additionally has M4 ending well before wing margin (Fig. 17A ), as opposed to A. parva where the vein ends at the wing margin (Fig. 18B ). This species does not have any immediately distinctive diagnosable character sets based on existing descriptions but can be identified based on the provided key. Chaetotaxy as observed: 2 vibrissae; 3 moderately strong proclinate interfrontal setae; 2 postpronotal setae; 1+1 notopleural setae; short weak biseriate acrostichal row; 1+3 dorsocentral setae; 1+1 supra-alar setae; postalar and intrapostalar setae present; 1 weak acrostichal prescutellar setae; scutellum with 1 discal setulae; katepisternal seta missing/indistinct.
