Parachinaviacreolea Roche, 1977:565 (nov.sp.); Gerlach et al. 2005:107 (distribution). Type-locality: Seychelles.

Male. Rostrum just attaining metacoxae (Fig. 3). Measurements (mm±standard deviation): Total length 9.26±0.29, total width 5.20±0.38, head length 1.93±0.11, head width 2.58±0.11, interocular distance 1.48±0.04, interocelar distance 0.88±0.04, head length in front of eyes 0.93±0.04, antennal segment I 0.58±0.02, antennal segment II 0.98±0.07, antennal segment III 1.28±0.02, antennal segment IV 1.43±0.09, antennal segment V 1.42±0.07, rostral segment I 0.73, rostral segment II 1.33, rostral segment III 0.93, rostral segment IV 0.97, pronotum length 1.67±0.28, pronotum width 5.47±0.38, scutellum length 3.33±0.00, scutellum width 3.33±0.19. Pygophore: excavation of ventral rim occupying more than median third of this structure (Figs 4, 6). Parameres: apical portion almost as wide as basal portion; apical margin obtusely rounded; apical process inconspicuous (Fig. 7-8).

Female. Unknown.

Comments. Roche (1977) mentioned that this species was apparently rare, and until recently it was known only from type material. More recently, Gerlach et al. (2005) extended its distribution. Distinguished from P. prunasis nov. comb. by shorter rostrum, ampliate excavation of ventral rim of pygophore, and narrower parameres, obtusely rounded at apex.

Holotype ♂ with the following labels (pygophore dissected): [Seychelles, Mt Fleuri, Mahe, 19.III.1972, P.J.L. Roche // Holotype //7178// Parachinavia creolea gen. & sp.n., P.J.L. Roche det. 1975] (NHM).

Paratype ♂ with the following labels (pygophore dissected): [Seychelles: Mahe, Mt Fleuri, 10.I.1972, P.J.L. Roche // Paratype //6712// Parachinavia creolea gen. & sp.n., P.J.L. Roche det. 1975] (MRAC).

Distribution (Fig. 22). Seychelles, known from Mahé (Mt. Fleuri) and Silhoutte islands.
