Protrellus aurifluus ( Chitwood, 1932) Basir, 1956 (Thelastomatoidea: Protrelloididae )

Females of this species were recovered from P. fulvescens in 2 localities (Table 1).

Measurements (in micrometers). Female (N = 9): Body length 3403 ± 590 (2625–4300); maximum width 171 ± 30 (130–205); buccal cavity 12 ± 2 (10–15); oral annule length 7 ± 1 (6–8); oral annule width 25 ± 2 (23–28); second annule length 15 ± 2 (13–18); second annule width 40 ± 1 (38 – 41); nerve ring 101 ± 35 (70–143); excretory pore 138 ± 14 (125–170); esophagus 305 ± 25 (268 – 353); corpus length 233 ± 35 (194–308); corpus maximum width 35 ± 4 (30–43); isthmus 16 ± 4 (11–20); bulb length 66 ± 7 (50–73); bulb width 65 ± 6 (58 – 78); vulva from anterior end 178 ± 12 (165–198); vulva from posterior end 3397 ± 591 (2619–4296); tail 126 ± 29 (85–173); body width at tail 76 ± 12 (63 –88); egg length 82 ± 6 (73 – 96); egg width 40 ± 3 (35 – 45); a = 20 ± 2 (17–23); b = 11 ± 2 (9–15); c = 29 ± 10 (18–43); V = 5 ± 1 (4–6).

Protrellus aurifluus was found in 2 localities (Noxubee and Plymouth Bluff) in P. fulvescens (Table 1). This host constitutes a new record. The type host for P. aurifluus is P. lata , from North Carolina and Maryland, and an additional report from P. uhleriana from North Carolina was previously reported ( Chitwood, 1932; Hatcher, 1939). I have also recovered P. aurifluus from P. virginica in central Ohio (Carreno, unpublished results). Thus, P. aurifluus is not host specific in spite of its occurrence in only one Parcoblatta species in the current study. Measurements corresponded to those provided by Chitwood (1932).
