Macrosoma albida is moth-like butterfly described by William Schaus in 1901. It belongs to the family Hedylidae. [1] Originally it belonged to the genus Hyphedyle . [2]

Contents

Distribution

The species is found in Costa Rica, [3] at altitudes between 0 and 700 meters in the Cordillera de Guanacaste [3] as well as in Rio de Janeiro, eastern and southern Brazil. [2] [3] [4]

Description

Wings

Adults has white wings with a black spot; the forewing has black irrorations on both surfaces at base of costa. [4]
The length of the forewing can be 17–22 mm:

Genitalia

Male

Following are the characteristics of the male genitalia: [4]

  • The medial component of gnathos is tongue-shaped but not down curved.
  • Broadly terminating denticulate lateral components.
  • Valva is subrectangular with digit-like projection.

Female

The female genitalia is same as M. rubedinaria shows the following features: [4]

  • The anal papillae is more pointed than rounded.
  • Long ductus bursae.
  • Denticulate signum in the corpus bursae.

Antenna

The antenna of M. albida is not bipectinate. [4]

Diagnosis

The wing pattern is distinct. Whereas in M. ustrinaria the wings bear scattered irrorations, in M. albida the irrorations are confined to the base of the costa of the forewing. The male genitalia are similar to those of M. ustrinaria, but differ slightly in the shape of the valva. [4]

Hedylidae, the "American moth-butterflies", is a family of insects in the order Lepidoptera, representing the superfamily Hedyloidea. They have traditionally been viewed as an extant sister group of the butterfly superfamily Papilionoidea, but a 2014 phylogenetic analyses has suggested Hedylidae is a subgroup of Papilionoidea, and not a sister group, and are more accurately referred to as butterflies rather than moths. They are represented by a single Neotropical genus Macrosoma with 35 currently recognized species.

<span class="mw-page-title-main">Lepidoptera genitalia</span> Study of the genitalia of butterflies and moths

The study of the genitalia of Lepidoptera is important for Lepidoptera taxonomy in addition to development, anatomy and natural history. The genitalia are complex and provide the basis for species discrimination in most families and also in family identification. The genitalia are attached onto the tenth or most distal segment of the abdomen. Lepidoptera have some of the most complex genital structures in the insect groups with a wide variety of complex spines, setae, scales and tufts in males, claspers of different shapes and different modifications of the ductus bursae in females.
