Indotritia (lndotritia) javensis

( Sellnick, 1923) ( Figure 19 )

Diagnosis — Measurements of specimen from MAG-131: prodorsum: length 384, width 268, height 141, setae: ss 159, in 106, le 68, ro 63; notogaster: length 656, width 465, height 525, setae: c 1 126, c 3 53; genital and aggenital plates 164×83, anal and adanal plates 328×76.

Rather large-sized species; colour brown. Prodorsum with 2 pairs of robust, divergent lateral carinae; sensilli setiform, smooth; rostral and interlamellar setae rigid, setiform, erect, interlamellar setae covered with small spines, rostral setae rough; lamellar setae procumbent, thin; exobothridial setae vestigial. "Notogaster" with short (c 1 <c 1 - d 1), setiform setae covered with small spines, setae c 3 and ps 3 thinner than others, setae c 1 and c 2 remote from anterior margin, setae c 3 near the border. Ventral region; setae h of mentum considerably longer than distance between them; epimeral formula: 3-0-2-2; scissure between genital and aggenital plates sometimes long, reaching setae g 6; 9 pairs of genital, 2 pairs of aggenital setae; one pair of anal and 3 pairs of adanal setae; lyrifissures iad situated between setae ad2 and ad3. Leg chaetome: I: 1-4-5(2)-5(1)-22(3)- 3, II: 1-4-4(1)-3(1)-19(2)-3, III: 3-2-3(1)-3(1)-14-3, IV: 3-2-2(1)-3(1)-11-3, femora I with distinct spines in dorsodistal end, setae u’ on tarsi IV in shape of thick spines.

Remark — This species is similar to I. paulyi Niedbała, 1988 but has vestigial exobothridial setae, shorter notogastral setae, especially interlamellar and rostral setae of prodorsum and adanal setae ad 1 and ad 2.

Species new for Afrotropical Region.

Distribution — Pantropical species introduced to southern and eastern parts of Palaearctic.
