Eulimnadia antillarum ( Baird, 1852)

Limnadia antillarum Baird, 1852: 30 , tab. 23, fig. 1. — Packard 1874: 314. — Simon 1886: 456. — Lilljeborg 1889: 424. — Brtek 1997: 56.

Eulimnadia antillarum – Ihering 1895: 173. — Daday de Deés 1926: 517, fig. 127. — Martin 1989: 108, fig. 5A.

TYPE LOCALITY. — Island of Hispaniola.

MATERIAL EXAMINED. — Mexico. 2 eggs (MNHN-Bp320) ; 3 eggs (MNHN-Bp321). — Island of Hispaniola , female without eggs (MNHN-Bp322) .

RANGE. — In addition to the type locality, this species was indicated in Mexico ( Daday de Deés 1926) and in Brazil ( Lilljeborg 1889). The latest citation is doubtful because the diagnostic caudal region is unknown in this population.

EGG MORPHOLOGY

Four types of egg morphologies are represented: one (from MNHN-Bp320) is similar to those of E. mauritiana , one (from MNHN-Bp321) is similar to those of E. acutirostris , one (from MNHN-Bp 320) is similar to those of E. chaperi , and one (from MNHN-Bp321) is similar to those of E. geayi . A cylindrical egg with equal border size was also found in MNHN-Bp321 but unfortunately destroyed during the critical point operation and was observed only under stereomicroscope.

REMARK

As cylindrical with equal border size eggs are not present in other samples in MNHN, this type of eggs could be not a contamination, and gives impetitus for finding current populations of E. antillarum in Mexico.
