Name
Asklepia Liebke, 1938 – Wikispecies link – Pensoft Profile
- Asklepia Liebke, 1938:113
Type species
Asklepia strandi Liebke, 1938:113.
Derivation of genus name
Asklepius, a Greek God of healing. Why Liebke used this name is unknown. See: http://www.mythologydictionary.com/asclepius-mythology.html
Proposed english vernacular name
Neat pattern-wing beetles.
Diagnosis (Figs 29–55, 57–75). Size range – ABL = 1.95 mm to 3.74 mm; with the attributes of the genus Asklepia as described by Liebke (1938)[1]. Adults with head and pronotum smooth and shiny; elytron quadrangular, apically truncated, margin slightly oblique, pattern coloration with pale maculae (slightly flavotestaceous in some individuals); labial palpomeres pubescent, ultimate article globose basally and subulate apically; legs testaceous; basal antennomeres fulvous, medial antennomeres infuscated, apical antennomeres white (the number of basal, medial, and apical antennomeres is described for each species below). Abdominal sterna sparsely pubescent.
Species are arrayed across three species groups based mainly on the armature of the male aedeagal endophallus: geminata species group (endophallus without spines, Fig. 57), hilaris species group (endophallus with multiple spines, Figs 58–63), and pulchripennis group (endophallus with two spines, Figs 64–74). In addition, the species of the geminata species group have elytral striae and moderately convex intervals; the hilaris group members have explanate lateral margins on the pronotum while those of the pulchripennis groups are feebly beaded only in the anterior half.
Dispersal potential
The wings are fully developed in most individuals we have studied, thus it is likely that these beetles are moderate to strong flyers; however, in at least two species there are also brachypterous adults. This is unusual in lowland Amazonian species; for example, see Adis et al. (1997 [1998])[2] on a species of an odacanthine near Manaus, Brazil.
Geographic
distribution
(Figs 76–78). As currently known, the range of this genus extends in cis-Andean South America from southeastern Colombia south to Bolivia and east to Guyana and Belém, Brazil, and from there south to Entre Ríos Province, Argentina.
Way of life
These species live close to water in wet leaf litter and on aquatic vegetation (macrophytes) of backwashes along rivers, streams, and lakeshores of both Varzea and Igapó forests and among dead leaf accumulations on rocky or sandy stream banks. Immature stages are unknown; however, given the wide variation in adult size within a species as noted in the introduction, it is possible that larvae are ectoparasitoids (cf. Erwin 1967[3], 1979[4]; Frank et al. 2009[5]).
Notes
Not much has been previously published on this genus. We now know there are many undescribed species across the Amazon Basin and on the Guiana Shield and the southern part of the Brazilian Shield; hence it is not monobasic as reported by Reichardt (1974)[6]. Bates (1871)[7] actually described four species (assigned herein to Asklepia) placing them in the genus Eucaerus LeConte, none of which were recognized previously as an Asklepia species (cf. Liebke 1938[1]; Reichardt 1974[6]). Since the genus was in need of taxonomic revision, we have provided it here. Many areas of South America have not been sampled for very small water-side beetles; thus, it is likely many more species of this genus will be discovered in the future. As pointed out recently (Erwin et al. 2010[8]), many very tiny-sized carabid clades have gone mostly unnoticed. In the 1930’s, the discovery of Gehringia olympica Darlington served to adjust the search image of carabidologists toward a fractal universe smaller than previously used; however, such search image needs to be focused more in the rainforests of the world.

Key to the species of Asklepia Liebke, 1938
Note. Because of the variability within species and the marked similarity across some species, only features of the male genitalia provide reliable means for identification of some species. Unfortunately, we did not have at our disposal males of all the species to image.
