Dinaraea angustula (Gyllenhal) – Wikispecies link – Pensoft Profile
- Aleochara angustula Gyllenhal, 1810: 393; as Dinaraea: Klimaszewski et al. 2011[1]: 159.
Diagnosis
Dinaraea angustula (habitus Fig. 6a) may be distinguished from congeners by the following combination of characters: body length 3.3–3.7 mm; head, pronotum and elytra slightly glossy with dense microsculpture; pronotum broadest at middle and narrowest at apex and base; elytra at suture as long as or slightly shorter than pronotum, with dense punctation similar to that on pronotum; antennal articles 7–10 moderately transverse; male tergite VIII with four small apical teeth, all short and rounded and some additional tooth-like subapical structures (Fig. 6c); median lobe of aedeagus with straight and short tubus narrowly rounded apically and sometimes slightly hooked at apex (Fig. 6b); spermatheca with short pear-shaped capsule, and small apical invagination, stem long, straight medially and looped posteriorly, with slightly swollen apical part (Fig. 6e).
Description
Body length 3.3–3.7 mm; body dark brown with legs, antennae (at least basally), labial palpi and elytra yellowish- or reddish-brown, pronotum and abdomen lighter than head, sometimes entire body appears brown; head, pronotum and elytra slightly glossy, with dense microsculpture; abdominal microsculpture less dense and integument more glossy than that of pronotum and elytra; head about as broad as pronotum, genae slightly longer than eyes in dorsal view; pronotum broadest at middle, slightly transverse, usually longer than elytra at suture; elytra transverse, truncate posteriorly; abdomen subparallel; male tergite VIII with four small apical teeth, all short and rounded and some additional tooth-like subapical structures (Fig. 6c), sternite VIII produced apically (Fig. 6d); median lobe of aedeagus with short and straight venter of tubus and narrowly ventrally pointed apex (Fig. 6b); female tergite VIII concave basally and truncate apically (Fig. 6f), sternite VIII rounded apically and emarginated medially, antecostal suture slightly sinuate (Fig. 6g); spermatheca with short pear-shaped capsule, and small apical invagination, stem long, straight medially and looped posteriorly, with slightly swollen apical part (Fig. 6e).
Distribution
This Palaearctic species is adventive in North America (Klimaszewski et al. 2010[2]). The earliest Canadian records are: Elora, Ontario in 1975 (DEBU); St. Andrews, New Brunswick in 1978 (DEBU); Fairview, Alberta in 1982 (DEBU). The first North American records are: Buffalo and New York before 1889 (Fauvel 1889[3]); Davis, California before 1984 (Muona 1984[4]). In Canada, the species is known from Newfoundland and Labrador, Nova Scotia, Prince Edward Island, New Brunswick, Quebec, Ontario, Alberta and Yukon Territory (Klimaszewski et al. 2007[5], 2010[2], 2011[1], 2012[6], Majka and Klimaszewski 2008[7], Webster et al. 2009[8]). In the USA, it is reported from New York, Pennsylvania and California, but is likely more widely distributed in the northeastern states.
Collection and habitat data
In North America, this species is associated with soil and organic debris in agricultural fields and disturbed urban meadows. It is also found in marsh litter, in leaf litter in mixed forests, in compost, under bark of decaying spruce logs, amongst vegetation on a coastal sand dune, in litter in a cattail marsh, in leaf litter along a vernal pond, and in drift material along a lakeshore (Webster at al. 2009[8], Klimaszewski et al. 2010[2], 2011[1], 2012[6]). Illustrations and a description of the larva were published in Topp (1975)[9].
