First record of Neoempheria Osten Sacken (Diptera, Mycetophilidae) biology in the Neotropical region, with associations between its larvae and fungi.

Oliveira SS, Albertoni FF, Borkent CJ, Amorim DS - Biodivers Data J (2015)

Bottom Line: Members of the family Mycetophilidae (Diptera) have life cycles that are typically associated with fungus.The immature stages and adult of N.puncticoxa are described and re-described respectively, and high resolution images and illustrations of the habitus, wings, thorax, male and female terminalia, immatures, and in situ specimens are given.We report the first association between Mycetophilidae and fungi in the Neotropical region.

ABSTRACT

Background: Members of the family Mycetophilidae (Diptera) have life cycles that are typically associated with fungus. Their biology is relatively well known in the Palaearctic, though other regions are poorly known, and there are no associations recorded between mycetophilid immatures and fungi in the Neotropical region. Here we report the first association between a mycetophilid-Neoempheriapuncticoxa Edwards-and fungi in this region. Immatures of N.puncticoxa were collected on fungi and some were reared in the laboratory until adult emergence. The immature stages and adult of N.puncticoxa are described and re-described respectively, and high resolution images and illustrations of the habitus, wings, thorax, male and female terminalia, immatures, and in situ specimens are given.

New information: We report the first association between Mycetophilidae and fungi in the Neotropical region.

Figure 1475323: Larva (pre-pupa), frontal view, hanging in its own silk in preparation for pupation. Substrate upside down.

Mentions: Head capsule relatively well sclerotized (Figs 7, 8, 9, 12c, d), bare, subrectangular, (anterior end slightly more slender than posterior end, as in the larvae of other mycetophilid genera, e.g., Brachypeza Winnertz—see Madwar 1937) and at least partially retractable into first segment. Separation between dorsal plates of head capsule not clearly evident, medial plate extending almost to the posterior capsule margin. Eye posterolateral to the antenna (Figs 7, 9). Occipital foramen ventrally triangular, at about distal fourth of head capsule. Mouthparts occupying ~1/3 of anterior head capsule. Labrum wide, fleshy. Premandible with row of elongated, flexible teeth, supported by a pair of lateral chitinous arms. Mandible semicircular and bearing two rows of medially directed teeth (Fig. 8b) as found in other Mycomyiini species (Krivosheina and Zaitzev 2008). Maxilla with rounded, medially directed, edge bearing a row of medially directed teeth (Figs 8b, 9).
