Type material. Female holotype, 6 female and 2 male paratypes from Ducula luctuosa (Temminick) ( Columbidae ); INDONESIA: Sulawesi Island, coll. Rvedel.

Type material deposition. All material is deposited in the AMU (Reg. No. AMU-SYR. 503), except 1 female paratype in the ZSM (Reg. No. ZSM- 20112052) and 1 female paratype in the ZISP (Reg. No. ZISP-AVB011- 2908 - 025).

Additional material. Two females and 1 male from Ducula spilorrhoa (Gray) ( Columbidae ), PAPUA NEW GUINEA: 17 March 1911, coll. Wiedenfeld (deposited in the AMU (Reg. No. AMU-SYR. 504)). Eight females from Ptilinopus jambu Gmelin ( Columbidae ), INDONESIA: Sumatra, Lampung Province, 1908, coll. Elbert (deposited in the AMU (Reg. No. AMU-SYR. 505), except 1 female in the ZSM (Reg. No. ZSM- 20112053) and 1 female in the ZISP (ZISP-AVB 011- 2908 -026). Five females from Ptilinopus melanospilus Salvadori ( Columbidae ), INDONESIA: West Java, Bogor, Cisaura, Tugu Selatan, Mount Gede Pangrango National Park, Gede Mt., 2 June 1909, coll. Primavesi (deposited in the AMU (Reg. No. AMU-SYR. 506)). Six females from Ptilinopus porphyreus Temminck ( Columbidae ), INDONESIA: Java, no other data (deposited in the AMU (Reg. No. AMU-SYR. 507), except 1 female in the ZSM (Reg. No. ZSM 20112054) and 1 female in the ZISP (Reg. No. ZISP-AVB011- 2908 -027)). Three females from Ptilinopus regina Swainson ( Columbidae ), INDONESIA: Mariana Islands, no other data (deposited in the AMU (Reg. No. AMU-SYR. 508)).

Differential diagnosis. Peristerophila lature is similar to P. columbae (Hirst) known from Columba livia Gmelin and Zenaida auriculata ( De Murs) ( Columbiformes : Culumbidae) ( Kethley 1970; Skoracki 2011). In females of both species, the number of chambers in medial and lateral branches of the peritremes are similar; the hysteronotal shield is fused to the pygidial shield; setae d 2 and e 2 are unequal in length. This new species differs from P. c o l u m ba e by the following features: in females of P. lature , the length ratio of setae ve: si: se is 1: 2.2–2.6: 4.6–5.1; the pygidial shield is punctate in the posterior part. In females of P. columbae , the length ratio of setae ve:si:se 1: 1.5: 9.5; the pygidial shield is apunctate in the posterior part.

Etymology. The specific ephitet “ lature ” is adapted from the name of the Indonesian god of the abyss—Lature.
