The Standard Data for the type are : 
AW 70.0, PW 42.0, SB 61.6, ASB 14.0, PSB 58.8, SD 72.85 A-P 50.42. 
AL 30.8. PL 29.4, Sens. 33.6. 
Loc. and Host . — Described from the type and paratype attached to two Dolichopodid flies collected 
in a light trap at Merbein, Victoria, 2.xii, 1951. (Mrs J. M. Mackerras). 
Genus Womersleyia Radford 1946 
Parasitology, 1946, 37, 48-51, figs. 19-23. 
Re-diagnosis of Genus. — Leeuwenhoekiidae, subfamily Apoloniinae, with legs all 7- 
segmented. Tarsal claws paired, with median empodium. With 2 AM setae present and PL 
on the scutum. Scutum with strong antero-median conical process on which are the two AM 
setae. Scutal setae stout and spine-like with distal fine dilations, but PL not so stout as AM 
and AL. Sensillae fine and filamentous, with fine distal ciliations. Palpal claws single but 
bifid and deeply cleft, short and curved; tarsus terminating in two stout, straight spines or setae 
with fine distal ciliations; as well as several long finely ciliated setae. Chelicerae short and 
curved, non-serrate, with a small apical tricuspid cap. Eyes 2+2, on ocular shields, posterior 
the smaller, and placed close to posterolateral corners of scutum. 
The above re-diagnosis of the genus is based on a paratype specimen kindly given to me 
by Dr. Radford, and takes into account the various characters now considered of generic 
importance in the taxonomy of this family of mites. 
Both Radford and R. F. Lawrence, 1949, placed the genus in the Leeuwenhoekiinae 
Womersley 1944, but it more naturally belongs to the subfamily Apoloniinae.

Womersleyia minuta Radford, 1946 (figs. 4 A-G). 
Parasitology , 1946, 37, 51, fig. 19-23. 
This very interesting species was described from specimens at first collected from mud in 
a Pandanus swamp from Gan Island, Addu Attol, in the Maldives, 20. xii. 1944, and later found 
to be parasitic under the wings of grasshoppers belonging to the three families Acrididae, 
Tetrigidae and Tettigoniidae. 
The following re-description is from a specimen from grasshoppers given to me by 
Dr. Radford. 
Re-description of Larvae . — Shape oval. Colour in life reddish. Length (engorged) 400[ ji , width 335'i.. 
Scutum as figured, wider between PL than between AL ; anteriorly with a strong and pronounced conical 
process which carries the two AM setae; postero-lateral corners produced, and posterior margin lightly 
concave; the scutal setae are short, stout and spine-like with short fine distal ciliations and arise from strong 
tubercles; sensillae fine and filamentous, ciliated distally with the bases in a line midway between lines of 
AL and PL; from the antero-lateral corners a strong line runs posteriorly to behind the sensillae bases, 
and from the posterior corners also a strong line runs anteriorly meeting and thinning out medially in line 
of PL. Eyes 2+2, large and on ocular shields close to the postero-lateral corners of the scutum. Chelicerae 
small, but rather strongly curved, non-serrate, with only an apical tricuspid cap. Galeal setae nude. 
Palpi stout, tibial claw rather short, bifid, nude and deeply cleft and lightly curved ; setae on palpal femur 
and genu fine and shortly ciliated, on tibia, only the ventral branched; the tarsus with a pair of strong thick 
apical spines or setae which are distally finely ciliated; as well as several normal long and ciliated setae. 
The dorsal setae are 6.6.64.2. to 34^ long. Ventrally, with a pair of ciliated setae on maxillae, two on 
coxae I, and one on coxae II and III, a pair between coxae III, and thereafter ca. 6.64.2. varying from I’jp 
anteriorly to 24 |jl posteriorly. Legs: I i88u long, II i6op., Ill 206 p; no long nude setae on tarsi or 
metatarsi III. 
No trace of trachea or true spiracles between gnathosoma and coxae I. 
The Standard Data for the above paratype compared with those given by Radford (in parentheses) are : 
AW 33.5 (34.0), PW 50.25 (55.0), SB 26.8 (34.0), ASB, to base of process 23.45, t0 a P ex of 
process 39.85 (40.0), PSB 23.45 (17.0), SD to base of process 46.9, to apex of process 63.3 (60.0), 
A-P 26.85 (25.0), AM 13.4 (17.0), AL 16.75 (17*0)3 PL 16.75 (20.0), Sens. 33.5 (51.0).
