Measurements.
Body length:
3.25–3.55 mm
(mean
3.41 mm
,
holotype
3.40 mm
), width:
1.45–1.65 mm
(mean value
1.58 mm
,
holotype
1.50 mm
).
Description.
Similar to the nominotypical subspecies in habitus. Sides of elytra subparallel medially, distinctly tapering to apex in apical fourth, hence beetle appears more elongate and thinner (
Figure 3F
).
Pronotum with maximum width near midlength, sides more or less evenly curved over entire length.
Elytra widest in first third of their length, then tapering distinctly to apex. Punctuation of elytral disc very fine, distance between punctures about two to three times as large as their diameter.
Male: dorsal surface shiny. Claws of fore tarsi broadened, strongly hooked. Median lobe of aedeagus in ventral view (
Figure 2G
) regularly tapering to apex, apical part long and thin, slightly turning to right.
Female: microreticulation of elytra usually more distinct than in males, so surface subopaque. Claws of fore legs thin, only slightly curved.
Differential diagnosis.
The new subspecies can only be reliably distinguished on the basis of the male genitalia.
Hydroporus
b. cariaensis
ssp. nov. has the apical part of the median lobe distinctly prolonged, very thin, turning slightly to the right in ventral view (
Figure 2G
).
Etymology.
The new subspecies is named after the ancient region of “Caria” located in the present Mu
g
la province, where the
type
locality is situated.
Habitat.
Collected in small streams.
Distribution.
Known from several localities in extreme south-western
Turkey
(Mu
g
la province), and from the Greek Island of Rhodes (
Figure 6
).
