Description
(
holotype
, male). Body length
2.6 mm
. Body reddish to reddish brown, elytra with vague darker markings; legs and antennae reddish.
Antero-lateral margins of frons simple. Gular rugules of different size, anteriorly larger, ordered and fused as in
Fig. 139
. Clypeal granules minute and distinct. Setation of head generally rather fine and sparse, hairy, mostly appressed on vertex, with a few longer, raised setae medially near base. Antennae moderately long; antennomeres III–V 1.8 times, X 1.3 times as long as wide; setation mostly fine, antennomere I conspicuously setose, including several long bristly setae.
Pronotum globose, 1.5 times as long as wide, its lateral margins rather strongly, evenly convex in dorsal view; posterior collar very narrow and inconspicuous. Pronotal horn robust and wide, subtriangular, its posterior angles distinct in dorsal view; horn margins armed with 3 lobules on each side, posterior lobules very wide, apical lobule simple, widely rounded; horn crest very conspicuous, strongly raised, short and situated rather posteriorly, with rugules mostly fused and forming complete semicircular rim; submarginal rugules mostly coarse and distinctly spaced; single large, longitudinal median rugule and several minute granules scattered posteriorly. Setation whitish to pale yellowish, largely scaly, fine and inconspicuous on pronotal horn dorsally; scales on pronotal disc rather uniform, appressed, elongate, truncate apically, glossy, distinctly spaced (surface visible); antebasal paired setae absent medially, difficult to recognize laterally owing to presence of numerous additional tactile setae.
Elytra 1.7 times as long as wide; omoplates and postbasal impression absent. Setation whitish and pale brownish, forming very vague brownish marking, coarse to nearly scaly, appressed, evenly ordered; scales linear, rounded to subtruncate apically, somewhat glossy, rather widely spaced (surface clearly visible,
Fig. 176
); tactile setae rather numerous and distinct, also present in apical third.
Male characters. Sternum VII nearly simple. Tergum VIII and aedeagus as in
Figs 58, 59
.
Variation.
Body length (♂
♀
)
2.2–2.6 mm
. Elytra rarely unicolorous and scales uniformly whitish to silvery (single specimen from Regans Ford).
Elytra in females nearly subtruncate apically, with apical margin slightly concave near median apical angle.
Differential diagnosis.
Mecynotarsus hirtipennis
sp. nov.
is undoubtedly close to
M. bullatus
sp. nov.
as suggested by similarity of both external (triangular pronotal horn, semicircular crest rim, numerous tactile setae) and male characters. It differs from the latter species especially by the somewhat shorter, uniformly appressed, simple setation of the pronotal disc, more slender antennae (basal antennomeres), longer tactile setae on the elytra, nearly subtruncate elytral apices in the females, and by the unevenly narrowing, apically rounded parameres.
Etymology.
The species name is a Latin adjective
hirtipennis
, -
is
, -
e
, composed from the Latin words
hirtus
(= hirsute) and
pennes
(= wings, elytra); named in reference to the numerous, very long tactile setae of the elytra.
