Phalangopsina dubia ( Bolivar, 1900)

( Figs 6 , 7 A–D, Table 2)

Arachnopsis dubius Bolivar, 1900 (1899) : 803. Phalangopsina dubia, Chopard, 1933a: 166 .

Type material: Lectotype here designated: 1 female, Maduré, n°1.244, Arachnop. dubius sp. n. [handwritten label by I. Bolivar], identified syntype of Arachnopsis dubius by M. Paris, MNCN (right PIII and antenna missing). Paralectotype, here designated: 1 female, Indes Or. (P. Castets) / Syntype [of Phalangopsina dubia ], test. M. Paris, 1991, ex. Coll. Pantel (MNHN-ENSIF2932).

Examined material: Female paralectotype. Male genitalia previously observed and figured by L. Chopard (1933a, Fig. a, b).

Diagnosis. According to Bolivar (1900), Chopard (1933a) and type observation, and in addition to the characters of the genus: Very small species (see Table 2). Colouration. Head dorsum yellowish ( Fig. 7 C), with three short black lines at the level of the fastigium; face, cheeks and lateral lobes of pronotum shining black ( Fig. 7 A, B); scape yellowish; legs I and II yellowish annulated with dark; TIII yellowish with unclear apical and distal brown rings; FIII yellowish striated with brown ( Fig. 7 D). Meso, metanotum and first tergites lightly coloured on mid dorsum ( Fig. 7 B, C). Male with small, slightly overlapping FWs ( Chopard 1933a, Fig. a). Male genitalia. Pseudepiphallic sclerite with a median distal part returned overhead, narrowed at its base, and wide distally ( Fig. 6 D, F); pseudepiphallic lateral lobes made of a long hook articulated at its base on a small and narrow lateral sclerite ( Fig. 6 F); pseudepiphallic parameres made of a wide outer lobe, bearing a long crest on its outer margin and many picots on its inner side ( Fig. 6 D), and a flap-like, smaller inner lobe ( Fig. 6 E). Female. Ovipositor longer than FIII and TIII, but about 8–9 mm long; straight, with the apex slightly curved upward. Female genitalia as on Fig. 6 G, H.

Additional characters to description. Scape as long as wide ( Fig. 6 A). Maxillary palpi quite short; joint 5 distinctly widened distally ( Fig. 6 B). TIII inner apical spurs as in P. bolivari Desutter-Grandcolas n. sp. ( Fig. 8 C); outer spurs as on Fig. 6 C; inner serrulation in paralectotype female: no spine between spurs 1 and 2, one spine between spurs 2 and 3, and between spurs 3 and 4, four or five spines above spurs; outer serrulation: two spines between spurs 1 and 2, two to three spines between spurs 2 and 3, three spines between spurs 3 and 4, four to seven spines above spurs. Basitarsomeres III with two rows of small spines dorsally: two inner spines and four outer spines, in addition to distal spines.

Colouration. Median part of meso-, metanotum and first tergites lightly coloured, prolonging the clear head dorsum and pronotum dorsal disc ( Fig. 7 A–C). Distal part of palpi joints darker. FIII as on Fig. 7 D.

Female. Subgenital plate bisinuate distally.

Measurements. See Table 2.

Pron-L Pron-W FIII-L TIII-L Ovip-L Lectotype ~1.5 - 7.1 6.9 8.8 Paralectotype 1.4 - 6.8 6.4 7.9

Variation. The paralectotype female has a more contrasted colour pattern for the head and pronotum, laterally deep black, and dorsally yellowish.

Habitat. Unknown.
