Containing group: Tenebrionoidea

Introduction

Ciidae is a family of minute beetles with nearly 650 described species in 42 genera, and hundreds of new forms known from museum and private collections (Lawrence 1967b; Lawrence 1971; Lawrence and Lopes-Andrade 2010; Lopes-Andrade and Lawrence 2005; Lopes-Andrade 2008b; Mellié 1849). Although distributed worldwide, the group is most diversified and least studied in subtropical and tropical regions. Ciids are diverse and abundant in most terrestrial environments, with both specialist and generalist species, endemic and widely distributed species, and so they are particularly suitable for broad ecological and biogeographical studies.

Biology and Ecology

Most ciids are true mycetobionts: Larvae and adults both live and breed in reproductive structures (basidiomes) of macrofungi (Lawrence 1973; Orledge and Reynolds 2005). They usually tunnel into and feed internally on the sterile supporting tissue of the more persistent basidiomes (Lawrence and Lopes-Andrade 2010). The most common hosts are from the families Polyporales and Hymenochaetales, but species of Orthocis Casey usually breed in Auriculariales (Lawrence and Lopes-Andrade 2010; Lopes-Andrade 2010b). The hosts are usually colonized after spores have been shed and sometime long after the fungus dies (Lawrence and Lopes-Andrade 2010). However, there are field observations and experimental evidence showing that ciids may consume live fungus and cause a significantly decrease in the area of functional hymenium, reducing fungal reproductive fitness (Guevara et al. 2000). Therefore, ciids may be considered saprophagous on decaying basidiomes or parasites of live fungi. In the latter perspective, the evolution of certain characteristics of ciid host fungi (such as chemical composition, consistency and phenology) can be interpreted as being driven by fungivory. Adults of apterous and micropterous species are usually collected in leaf-litter, but it is still unknown whether they are saprophagous on debris or associated with microfungi, or are found there while dispersing between basidiomes (Lopes-Andrade 2007a).

Ciidae are possibly the most speciose, frequent and abundant beetles associated with persistent basidiomes that grow in dead or live tree-trunks, and so they are directly involved in the decaying process of these fungal structures. In doing so, the ciids render important environmental services in nutrient cycling of elements such as cadmium, chromium, molybdenum, manganese and selenium, which are usually concentrated ten times more in basidiomes than in the substrate they use. Basidiomes are rich in proteins and carbohydrates and have great amounts of biologically important elements such as phosphorus and nitrogen, which may accelerate the development of larvae of beetles feeding on them (Martin 1979). However, basidiomes also have high concentrations of toxins, such as phenols, pyrones and heterocyclic nitrogen complexes. As the ciids are successful in consuming basidiomes they certainly have physiological mechanisms to avoid the toxic effects of these substances.

Characteristics

Ciids are tiny beetles and adults of most species have a length of 1 to 3 mm. However, a few species may be near 0.5 mm long, and some Cis Latreille and Xylographus Mellié may be “very large” and reach around 7 mm. Sexual dimorphisms occurs in the majority of species, in which males have tubercles and/or horns in the frontoclypeal ridge and/or the anterior pronotal margin. Males of most species also have a sex patch at the first abdominal ventrite that is possibly glandular and involved in sexual pheromone secretion (Lopes-Andrade et al. 2003). In one species, Phellinocis romualdoi Lopes-Andrade & Lawrence, females also have such an abdominal sex patch, but it is smaller than in males (Lopes-Andrade and Lawrence 2005). In Cis taurus (Reitter), Ceracis cornifer (Mellié) and others, frontoclypeal horn(s) may be as long as or even longer than pronotum.

Ciidae (except for Sphindocis denticollis Fall) may be recognized by the combination of morphological features provided below (sensu Lawrence 1974b; Lawrence and Lopes-Andrade 2010):

Adults:

The tarsal formula is described as 3-3-3 in Trichapus Friedenreich and Paratrichapus Scott (Friedenreich 1881; Scott 1926). Trichapus includes two species: T. pubescens Friedenreich, the type-species, which is possibly a Cis of the taurus gp.; and T. glaber Friedenreich, which is possibly a Porculus (Lawrence 1987). The drawings and description of Paratrichapus sechellarum Scott, the unique species of the genus, shows that it’s possibly a Xylographus (see Scott 1926). Therefore, their tarsal formula is possibly 4-4-4, rather than 3-3-3.

Similar antennal sensillifers occur in other tenebrionoids, especially in some Tenebrionidae (Lawrence 1971), and a sex patch in the first abdominal ventrite occurs in species of unrelated polyphagan families such as Anthribidae, Bruchidae, Erotylidae and Tenebrionidae (Faustini and Halstead 1982).

Larvae:

Body elongate, more or less parallel-sided, subcylindrical, slightly curved ventrally. Surfaces relatively smooth and usually lightly pigmented, except for mouth frame and tips of urogomphi, rarely with light tergal plates on most segments, smooth with vestiture of scattered, long simple setae (Costa et al. 1988; Lawrence and Lopes-Andrade 2010). Ciidae larvae have barely been studied and so it is early to provide general morphological patterns for the currently accepted suprageneric taxa.

Collecting and Breeding

Ciids are usually collected inside basidiomes of poroid fungi or by sifting litter. They are rarely attracted to light sources, so they are not frequently caught by malaise or other light traps. After collecting basiodiomes, it is important to let moisture evaporate before sorting the ciids.

If the aim is to breed ciids, basidiomes should be kept in plastic containers together with a small vial of silica gel or other another drying agent. Ciids are easily maintained under laboratory conditions and can be bred for several generations without addition of water or food (Klopfenstein and Graves 1992; Lopes-Andrade pers. obs.). Up to ten thousand individuals may live inside a single basidiome (Navarrete-Heredia 1987) and generation overlap is usually observed (Lawrence 1971).

Predators, Parasitoids and Phoretic Mites

Ciids have a patchy distribution, since they are usually aggregated in large numbers inside basidiomes. Therefore, they may be a major resource for several arthropods (Lawrence 1974a). A few ant species (mainly of Wasmannia Forel and Pheidole Westwood) were already observed performing aggressive behavior against adults and immatures of ciids (Lopes-Andrade pers. obs.), and Temnochila sp. (Coleoptera: Trogossitidae), Lyctocotis sp. (Heteroptera: Anthocoridae) and larvae of Lestodiplosis Kieffer (Diptera: Cecidomyiidae) are known to be predators (Lawrence 1974a). Several species of Allocerastichus Masi and Astichus Foerster (Eulophidae), Meteoms Haliday and Eubazus Nees (Braconidae), Jirnssoniella cuudata Kerrich (Pteromalidae), Plustanoxus chittendendi Ashmead and Cephalonornia perpusilla Evans (Bethylidae) are parasitoids of ciids (Coote 1994; Lawrence 1974a; Orledge et al. 2010). Phoretic mites, such as several species of Boletoglyphus Volgin and Boletacarus Volgin & Mironov (Acaridae), are commonly found on adult ciids (Klimov 1998).

Ciids as Pest and Invasive Organisms

Hadreule blaisdelli (Casey) was already recorded as a pest of fungi and lichen of North American herbaria (Lawrence 1971). Cis chinensis Lawrence is a known pest of commercial dried-fungi and is already free-living in Brazil, continental Europe, Asia and Réunion (Lopes-Andrade 2008a; Rose 2009). A few other ciids also have disjunct distributions and are considered invasive species in several regions, such as Ceracis cucullatus (Mellié), Cis bilamellatus Wood, Cis boleti (Scopoli), Cis creberrimus Mellié and Cis fuscipes Mellié (Lawrence 1971; Lopes-Andrade et al. 2009; Lopes-Andrade pers. obs.; Orledge et al. 2010).

Conservation Biology

There are evidences that ciids are affected by forest fragmentation and forest management. At least one species, Falsocis brasiliensis Lopes-Andrade, may be threatened (Lopes-Andrade 2007b). The species has a clearly disjunct distribution in the southern Neotropical region, occurring only in very small forest remnants in southeastern and northeastern Brazil. It has been barely collected, except for a great collection effort in recent years (Lopes-Andrade pers. obs.). Other ciid species are restricted to forest remnants and/or occur in threatened biomas, such as the Brazilian Atlantic Forest, and their conservation status should be evaluated.

Taxonomy

Relationship of Ciidae to other Cucujiformia

There are few available studies shedding light on the relationship of Ciidae to other cucujiform families, and internal relationships of the family are barely known. A phylogenetic analysis based on larval characters sustained Tenebrionoidea, including Ciidae and Prostomidae, as a clade defined by several autapomorphies (Beutel and Friedrich 2005). Ciidae is usually regarded as belonging to a tenebrionoid assemblage including Archeocrypticidae, Mycetophagidae, Prostomidae and Pterogeniidae (Buder et al. 2008; Lawrence 1971, 1982). However, there is no published work based on morphological and/or molecular data comprising species of all these families and a sufficient sample of cucujiform lineages to test this relationship.

The single published phylogenetic analysis, based on molecular data of several Ciidae taxa and species of other cucujiform families as outgroups, showed that Ciidae (Sphindociinae and Xylographellini were not included) is monophyletic (Buder et al. 2008). The authors found two alternatives for the relationship of Ciidae to other families: (i) Ciidae as an isolated clade in a cucujoid-tenebrionoid assemblage, sister to a clade comprising Anthicidae, Latridiidae, Monotomidae and Nitidulidae; (ii) a sister-group relationship to Nitidulidae. The authors emphasized that Archeocrypticidae and Pterogeniidae were not analyzed, so a close relationship to Ciidae could not be refuted. However, in none of the performed analyses did Ciidae appear close to Mycetophagidae, Tenebrionidae or Tetratomidae. 

Discussion of Phylogenetic Relationships

The current suprageneric classification of Ciidae does not reflect any robust phylogenetic scenario. The Californian Sphindocis denticollis (Sphindociinae) was included in the family based on the distinctive laciniar lobe of the larval maxilla, a feature not seen in any other cucujiform taxa (Lawrence 1974b). Among Ciinae, the most well-defined suprageneric taxon is Xylographellini, with the following possible apomorphies (Lopes-Andrade 2008b): (i) Antennal club compact; (ii) Each antennomere of the club bearing more than four sensillifers; (iii) Labial palpi inserted at the middle of prementum; (iv) Cuticular surface with small scattered globules, especially on pronotum and elytra; (v) Sternite IX in male with spiculum gastrale. Ciini and Orophiini do not have any well-defined apomorphy.

Each ToL branch page provides a synopsis of the characteristics of a group of organisms representing a branch of the Tree of Life. The major distinction between a branch and a leaf of the Tree of Life is that each branch can be further subdivided into descendent branches, that is, subgroups representing distinct genetic lineages.
