ABSTRACT

UNAB consists of several collections that seek to represent the insects of agricultural and forestry significance from the various regions of Colombia, especially the mountainous zone. In order to contribute to knowledge on the Diptera diversity of Colombia found in agricultural ecosystems, the present study looked at the Micropezidae contained in this museum, along with the represented taxa, as well as its current curatorial status and geographic distribution in the country. Currently, the Taxonomic Central Collection houses 107 specimens from the Micropezidae family, which belong to the genera Cardiacephala, Grallipeza, Grallomyia, Mesoconius, Micropeza, Plocoscelus, Paragrallomyia, Poecilotylus, Ptilosphen, Scipopus, and Taeniaptera, representing distribution in 57 municipalities and 12 departments (provinces) of the Colombian Andean region.

Key words: Andean region, Colombia, taxonomy, geographical distribution, agroecosystems, Insecta.

Introduction

The UNAB entomological museum currently contains several voucher collections of arthropods that are important to agriculture and forestry, coming from different regions of Colombia, especially the central area. It contains about 100,000 specimens from 20 orders and 160 families of Hexapoda and other Arthropoda. Among those specimens, there is an important representation of the Micropezidae family (Diptera: Nerioidea), leading to a preliminary understanding of the distribution of this family in Colombia.

Micropezidae is recognized by the following combination of characteres (Fig. 1): stilt-legged flies; wings with veins R4 + 5 and M converging toward the apex of the wing; absent ocellar setae and oral vibrissae; most neotropical species have a vertical row of setae, in a fan shape, in the posterior margin of the katepisternum; females with a seventh syntergosternite (fused 7 tergite and sternite), forming a rigid oviscape; male Micropezinae and Eurybatinae have a surstilus; and males of most species have a prominent bifurcated process in sternite 5 (Marshall, 2010).

They are f lies with cosmopolitan distribution, with a great diversity of species in tropical regions (Steyskal 1966, 1987; Ferro and Carvalho, 2014). Within the family, about 700 species of 60 genera are grouped into five subfamilies, including Calycopteryginae, Calobatinae, Eurybatinae, Micropezinae and Taeniapterinae (Marshall, 2010, 2012; Steyskal, 1987). Eur ybatinae, Micropezinae and Taeniapterinae are found in the Neotropics (Marshall, 2010, 2012, Ferro and Carvalho, 2014).

Studies of the Micropezidae family are few in Colombia. The latest and most extensive contribution came from Steyskal (1966), who recorded 11 genera and 40 species in this country.

Micropezidae exhibits a complex variety of feeding habits (Marshall, 2010, 2012). However, most species feed on decaying organic matter and some Mimegraffa species (Taeniapterinae) apparently affect healthy roots (Marshall 2010, 2012). Micropezidae f lies are not considered of agricultural importance. While most species are associated with native forests, some are commonly found in highly disturbed habitats and are frequently collected in agroecosystems (Harterreiten-Souza et al., 2014). Based on this collecting practice, a significant representation of Micropezidae is genera is housed in the UNAB Museum, a consideration that motivated us to produce the present contribution to knowledge of their distribution in Colombia.

 

Materials and methods

All specimens are individually point-mounted with a data-collecting label, placed into Ward-box cells with a green label containing the taxon name and a catalogue number (Fig. 1). To build a complete database with a digital program, each identification and dataset was given a Catalogue Number [UNAB No. Catal.]. In the present paper, we only transferred the collecting data.

Morphological characteristics were studied with the aid of a NIKON SMZ660 stereomicroscope, following keys of Marshall (2010) and Ferro and Carvalho (2014). Also, for some descriptions and diagnosis, the methodologies of Merritt and James (1973), Merritt and Peterson (1976), Steyskal (1987), Marshall (2004, 2011, 2013, 2015), Harterreiten-Souza et al. (2014), and Jackson et al. (2015) were employed.

Seeking to represent the geographical distribution of genera in Colombia, we built maps for each genus by gathering the information on the labels and employing the freely available program QGIS (QGIS Development Team, 2015). The distribution based on altitude (meters above sea level) was depicted as well. Abbreviations for some data on the labels are as follows: Fca., Finca (farm); Hda., Hacienda, a large land for farming or ranching; m alt., meters of altitude above sea level; No. Catal., Catalog Number; Vda., Vereda (a small group of dwellings in a rural area connected by a narrow country road or district).

 

Results

We studied 107 specimens of the Micropezidae family, so far representing 11 genera for Colombia, including Micropeza of Micropezinae, and Cardiacephala, Grallipeza, Grallomyia, Mesoconius, Paragrallomyia, Plocoscelus, Poecilotylus, Ptilosphen, Scipopus, and Taeniaptera of Taeniapterinae.

Geographical distribution

Based on the information associated with the examined material, we reported the Micropezidae family in 57 municipalities in the departments of Antioquia, Bolívar, Caquetá, Cundinamarca, Huila, Meta, Nariño, Putumayo, Quindío, Risaralda, Tolima, and Valle del Cauca. The Paragrallomyia and Taeniaptera genera accounted for the largest number of recorded locations.

The Central Taxonomic Collection (CTC) of the Entomological Museum UNAB contains specimens mostly from the central regions of the country. Because of this, most Micropezidae genera are recorded from two departments. From Antioquia, the following genera are recorded: Mesoconius, Micropeza, Paragrallomyia, Poecilotylus, Ptilosphen, Scipopus, and Taeniaptera; while from Cundinamarca, the genera are: Cardiacephala, Micropeza, Paragrallomyia, Plocoscelus, Poecilotylus, Ptilosphen, and Taeniaptera. Genera registered from only one department include Scipopus and Mesoconius from Antioquia, Cardiacephala from Cundinamarca, and Grallipeza from Putumayo.

Distribution above sea level

Specimens were collected from 2 to 2,600 m alt., with a Median of 820 m alt. (Fig. 2). This finding showed that most records come from lowlands in Colombia. Micropeza, Paragrallomyia and Taeniaptera showed the widest altitudinal range, from lowlands to high mountains. Micropeza was seen from 2 to 2,600 m alt., with a Median of 1,285 m alt and Taeniaptera was found from 40 to 2,558 m alt., with a Median of 1,495, with these two genera commonly found in the Colombian coffee zone. On the other hand, Paragrallomyia is found from 7 to 2,599 m alt., with a Median of 496 m alt., which would suggest a possible concentration of species in the lowland regions of the central zone of the country.

Figure 2

We only recorded two specimens of Mesoconius at 1800 and 2,550 m alt. According to Marshall (2015), species of this genus belong to highlands, with several Andean species found from 2,500 to 3,000 m alt.

Taeniaptera and Paragrallomyia

Taeniaptera sensu Steyskal (1966) used to be considered the largest and, taxonomically, one of the most complex genus in the Taeniapterinae subfamily. At the UNAB Museum, Taeniaptera sensu Steyskal (1966) was represented by 39 specimens from 30 municipalities and nine departments.

However, very recently, Jackson et al. (2105) proposed a reclassification of the Taeniapterinae subfamily, raising Paragrallomyia to the genus level and including within it many species that were previously considered as part of Taeniaptera sensu lato. Therefore, Taeniaptera is currently represented in UNAB by 16 specimens from the following departments: Antioquia, Caqueta, Cundinamarca, Meta, Risaralda, and Valle del Cauca, whereas Paragrallomyia is now the best represented genus at this Museum, containing 23 specimens from 18 municipalities from the departments of Antioquia, Caquetá, Cundinamarca, Huila, Meta, Putumayo, Tolima, and Valle del Cauca.

To identify the Paragrallomyia genus, Jackson et al. (2105) considered the following combination of morphological characteristics: maxillar palp securiform, R4+5 cell open at the margin of the wing, and having at least one dorso-central seta (Fig. 8).
