Abstract

A new species of opilioacarid mite, Neocarus belizensis sp. nov., is described from mid-level elevations in Belize's Maya Mountains. Laboratory observations confirmed that females nearly always deposit only one egg at a time, and that eggs are coated before deposition. Females guard both eggs and larvae. The larvae are non-feeding and molt quickly to protonymphs. Adults appear to facilitate feeding by protonymphs. Actual mating could not be observed, but pre-mating behavior is documented.

Introduction

Mites in the order or suborder Opilioacarida form a relatively small lineage, currently containing 9 genera and about 24 species (Walter & Harvey, 2009). Even so, Opilioacarida has an outsized importance in acarine systematics, because of its position as presumed intermediate between the two main lineages, the Acariformes and Parasitiformes (Grandjean, 1936). First described in 1902, the group has received relatively little attention for most of the 20th century, although there has been a notable increase in the number of studies devoted to descriptions of new species in the last decade (Bernardi et al. 2014; Bernardi, Klompen, Zacarias et al. 2013; Bernardi, Silva et al. 2013; Bernardi et al. 2012; Das & Bastawade 2006(2007); Vázquez et al. 2014, 2015; Vázquez & Klompen 2002, 2009, 2010, 2015). However, such a strong increase in attention for the group is not reflected in studies on their behavior. A few studies have addressed feeding modes (Vázquez & Palacios-Vargas 1988; Walter & Proctor 1998), or defensive behaviors (Coineau & Legendre 1975; Walter & Proctor 1998), but only a few anecdotal reports exist on egg deposition (Klompen 2000), and none on mating behavior. The availability of a number of live specimens of a new species from Belize has allowed the documentation of some additional data on opilioacarid feeding, as well as providing the first data on reproductive behavior and brood care. Rearing also allowed preliminary data on life tables for the immature instars.

The goal of this study is to describe the specimens observed as a new species and to document various aspects of their behavior.

Material and Methods

Specimens were collected by the first author on 19 November 2007, 1 November 2008, and 27 November 2010 in Belize (Maya Mountains, near caves at Rio Frio, 16.97°N 88.99°W, 490m elevation), an area is covered by temperate forest. The collecting site was located near a small river. Most specimens were hand collected from under moss and lichens on large standing live pine trees. A few other specimens were collected from litter in the surrounding forest. A total of 28 specimens were collected from this site. An additional seven specimens were reared from larvae bom in laboratory cultures.

Three pairs of one male and one female were each placed in small jars with a moistened layer of activated carbon and plaster of Paris (Walter & Krantz 2009). Each jar also contained a small piece of bark and a little moss from the tree on which the specimens were collected. Specimens were fed once a week; surplus food was removed after approximate 30 minutes (if the specimens were feeding immediately) or the next day. Removal of excess food was necessary to prevent fungal growth. Water was provided as needed in the form of small drops of water.

Behavioral observations were made 1-2x daily for 30 minutes (usually late morning and/or late afternoon), using a Zeiss Stemi 2000-c dissecting microscope. Recordings were made using a digital video camera (Sony Exwave HAD) mounted on the dissecting microscope.

Description. Most material was studied as slide-mounted specimens. For this purpose, specimens were dissected, cleared in lactic acid and mounted on slides using Hoyer's medium (Walter & Krantz, 2009). Frequently, parts of single specimens were mounted on multiple slides. Terminology for the palp tarsal sensilla follows Grandjean (1936) as modified by Vázquez and Klompen (2002).

Drawings were prepared using a Zeiss Axioskop A1 phase contrast microscope, connected to a drawing tube; measurements were taken using an ocular micrometer and are presented in micrometers (µm). Measurements for individuals are listed in Table 1, the text uses average +/- standard deviation. It should be noted that measurements of idiosomal length and width are distorted, as they are based on slide-mounted specimens.

    Material examined (preserved as slides). Belize: Cayo, Rio Frio Caves, 16.9705° N 88.9956° W, elevation 490m, coll. M. M. Vázquez, 27-XI-2010, ex under moss and bark on standing tree in pineoak forest (holotype female, 2 females). Same locality & collector, 17-XI-2007, ex under moss and bark on standing tree in pine-oak forest (1 female, 1 male); 19-XI-2007, ex litter in pine-oak forest, (2 males, 10 tritonymphs); 1-XI-2008, ex under moss on standing tree in pine-oak forest (1 female, 3 males, 1 deutonymph, 1 tritonymph); 2-XI-2008, ex medium high pine-oak forest (5 deutonymphs). Lab culture from holotype female (1 larva, 6 protonymphs).

    Etymology. The specific name is derived from the country where the material was collected, Belize. Belix is a Mayan word which means muddy water.

    Taxonomic remarks. Neocarus belizensis differs from previously described Mexican and Central American taxa by the combination of 5 d sensilla on the palp tarsus (4 in N. chactemalensis, N. nohbecanus, and N. orghidani), the absence of terminal sensilla on the female ovipositor (present in N. bajacalifornicus, N. chactemalensis, N. comalensis, N. nohbecanus), sternal setae st3 similar in shape to surrounding setae (shared with N. calakmulensis, N. chactemalensis, N. nicaraguensis, N. nohbecanus, and N. siankaanensis), and the absence of setae in the pregenital area of the female (shared with N. chactemalensis, N. nohbecanus, N. orghidani, and N. siankaanensis). Based on these characters, the new species is most similar to N. siankaanensis. Neocarus belizensis differs from N. siankaanensis by the presence of 4, rather that 3 lobes on the d sensilla of the palp tarsus (Fig. 4), the presence of the unusual type of r-type setae on the palp tibia, and the presence of distinct membranous projections in the ovipositor (both absent in N. siankaanensis).

  • Ecology and behavior

    Food source. Specimens were offered a range of food options, from pollen grains to crushed insects (Vázquez & Palacios-Vargas 1988; Walter & Proctor 1998). The best feeding occurred with pollen grains. Initially the mites were fed on pollen from Coccinia sp. (Cucurbitaceae), a decorative plant found in the university gardens (video clip 2:  https://youtu.be/cOYmCry84FI). The relatively small pollen were ingested whole. When feeding on this food source appeared to slow (after approximately 6 months), pollen of Hibiscus rosa-sinensis L. (Malvaceae) were provided. These pollen grains are substantially larger than those of Coccinia sp. The mites fed on them by breaking the outer covering and feeding on the softer content (video clip 3:  https://youtu.be/pPTAAmg3I0Q). Occasionally, the mites subsequently started feeding on the hard pollen cuticle. Co-feeding on single anthers was repeatedly observed, with no signs of aggression.

    Development. Specimens were kept alive for periods of 5–8 months. During this period reproduction took place for two pairs, resulting in eggs, larvae (video clip 4:  https://youtu.be/Qii102CjE84), protonymphs, and deutonymphs. Molting to tritonymphs was not observed. For one pair, the female produced at least 8 eggs over a period of about 8 months, for an egg-laying frequency of approximately one per 3–4 weeks. This time period corresponds fairly well to the 3-week time period between the 1st and 2nd egg laying period reported for N. texanus (Klompen, 2000). In most cases eggs are deposited one at the time, but we have at least one observation where two similar sized protonymphs emerged in a container with a single female, suggesting twin births are possible. Eggs hatch after about two weeks.

    Larvae molted to protonymphs in a few (2) days, while protonymphs molted to deutonymphs in about two weeks. Family groups of a pair of adults, larvae, protonymphs and a deutonymph were observed together. This may be artificial, because of the confines of the rearing containers, but it may also explain the observation that Opilioacaridae are often found in small groups.

    Larvae were not observed to feed, consistent with previous hypotheses (Klompen et al. 2015). All nymphal instars were observed feeding, usually on the same pollen grains as the adults. Protonymphs were also observed feeding on female excreta. These excreta were examined and contain partially digested pollen grains. Notably, these observations were isolated, disallowing conclusions on whether this type of feeding is common or maybe even required for protonymphal development.

    One female molted after about four months in culture, confirming the hypothesis that postimaginal molts occur in Opilioacaridae (Bernardi, Klompen, & Ferreira 2013; Coineau & Legendre 1975; Vázquez & Palacios-Vargas 1988). Moreover, this molt was not tied to earlier autotomy of legs, a common defense mechanism in these mites (Klompen 2000; Thaler & Knoflach 2002; Vázquez & Palacios-Vargas 1988), suggesting post-imaginal molts are not just for recovery of limbs. Neither does it appear to correlate with egg-deposition, as this female deposited eggs, molted, and continued depositing eggs, with little interruption.

    Reproduction. Earlier observations suggested that females coat their eggs (Klompen 2000), a hypothesis confirmed during the current study. Females held the eggs close to the gnathosoma with the help of their chelicera, rutella and palps, generating a rolling motion, presumably used to coat the egg (video clip 5:  https://youtu.be/8V-KwvMzzM8). The appearance of the egg changed after this treatment from white or yellowish white to a much darker color. The nature of the coating material and its function is still unclear, although some “waterproofing”, as observed in eggs of Ixodidae (Sonenshine, 1991), seems likely. Only when finished treating the egg did she deposit it under a small piece of bark or similar. The female remained near the egg, barely moving until the egg hatched.

    Mating behavior (1 pair). A major question regarding Opilioacarida concerns their mating behavior and specifically their method for sperm transfer. We have not been able to observe the latter, but can provide some observations on some aspects of pre-mating behavior. Three phases of pre-mating behavior could be distinguished. First female and male approach head to head. Their legs I touch at the telotarsus and both individuals maintain this position for a few seconds. Next the male touches the dorsum of the female, running the tips of his legs I all over her back. During this action she remains motionless. Next he turns 180° and the posterior parts of their bodies contact. Both hold this position for a brief period. As noted, actual mating was not observed, but at one time the male was seen holding some yellowish structure (oval and larger than an egg) in its mouthparts. Unfortunately he subsequently disappeared under a piece of bark, preventing further observations. It is possible that this was a spermatophore.

    Parental care (2 pairs). There are some indications of basic parental care. This includes putative guarding of the egg and larva by the female (noted above). The male may also be involved, as it remains very close to the female and egg/larva. Both female and male appear to facilitate feeding, or at least tolerate co-feeding, by the developing protonymphs (video clip 6:  https://youtu.be/1yhcA44QaY). In one case the female was eating pollen from a provided anther, when a protonymph appeared from under her (they are much smaller than the adults), and started to eat from the same site. The female immediately stopped feeding, but remained in place while the nymph was feeding. On another occasion adults were seen bringing anthers to protonymphs or guiding protonymphs to food.
