Phalangopsis longipes Serville, 1831

( Fig. 2 A-D; Table 1 )

Phalangopsis longipes Serville, 1831: 167 .

TYPE LOCALITY. — Amérique méridionale [Southern America] after Serville (1831), French Guiana and Suriname after Saussure (1878).

TYPE MATERIAL. — Syntype. ‘Amérique méridionale’ • 1 ♂; MNHN-EO-ENSIF 4009 .

REMARK

Serville (1831) described this species on one male and one female, which he considered immature (but see Saussure 1874, 1878). The male type is correctly identified in the MNHN collection. One additional female is identified Phalangopsis longipes Serv. in Serville’s handwriting, but it has posterior locality labels ( Guyane française, Saint Laurent du Maroni, Collection Le Moult / septembre). It may have been labelled in a second time by error, as three other females have the same origin. This female may represent the female syntype observed by Serville (MNHN-EO-ENSIF6828).

MATERIAL FROM THE MITARAKA. — French Guiana • 1 ♀; Monts Tumuc-Humac , Massif du Mitaraka, layon A; entre 54.4509 O 2.2357 N et 54.4557 O 2.2405 N; alt. entre 280 m et 365 m; 23.II.-10.III.2015; F. Legendre & S. Hugel leg.; fn. SH116, de nuit; MNHN • 2 ♀; Monts Tumuc-Humac , Massif du Mitaraka, GF DZ; 54.450137 O 2.233883 N; alt. 315 m; 23.II.-10.III.2015; F. Legendre & S. Hugel leg.; fn. SH179, SH180, de nuit; MNHN • 1 ♂; Monts Tumuc-Humac , Massif du Mitaraka, GF DZ; 54.450137 O 2.233883 N; alt. 315 m; 23.II.-10.III.2015; F. Legendre & S. Hugel leg.; fn. SH178, de nuit; MNHN .

MEASUREMENTS (IN MM). — See Table 1.

REMARK

The length of the ovipositor of the females collected in Mitaraka is variable (see Table 1 ), but extends the values given earlier for the species (Desutter-Grandcolas 1992a, 13.6-16.6 mm, mean 14.8, n = 9). The copulatory papilla is however very similar to that reported for that species in the same paper. The number of tergites with yellow bands on posterior edge also varies in the material at hand, until the third tergite for the specimen SH116 ( Fig. 1A ). Male genitalia are illustrated on Fig. 2 B-D.
