Redescription.
Body medium-sized, glossy, dark brown to blackish, and light-colored in some cases. First 2 antennomeres, maxillary palpi, and legs reddish and elytra pale and translucent with margins and median suture infuscate. Length [average] male,
4.4 mm
; female,
4.1 mm
.
Male
. Head (
Fig. 11A
) sub-pentagonal, widest at temples (in some cases at eyes). Disc, pubescent, covered with large punctures. Clypeus elongated trapezoidal, protruding beyond anterior margin of supra-antennal ridges, as long as almost 1/3 head length, slightly depressed in central part, surface glabrous and coriaceous; anterior margin narrow and shallowly emarginate. Epistomal suture with lateral portions lightly incurved and running posteriorly to level of anterior margin of eyes. Vertex slightly convex but flat and coriaceous near clypeus, posterior part weakly limited in median; mid-longitudinal suture present but not obvious, a little punctate; paralateral sutures present, long and almost connected to lateral portions of epistomal suture. Eyes with fine facets, convex, and usually shorter than temples (but a little longer in some cases). Temples rugose, and dilated posterolaterally, usually protruding laterally beyond eyes. Occipital suture with middle portion punctate but feeble in some cases; nuchal ridge interrupted in middle, dorsal basal ridge present.
Mandible (
Fig. 11C
) stout, falciform, strongly incurved; apex sharply pointed; two denticles on inner edge, one near middle and one near apex. Antenna (
type
II) as long as or a little longer than head and pronotum together, with apical antennomere a little shorter than two preceding together.
Pronotum transverse, broadest at near anterior 1/4, as wide as head or a little narrower in some cases. Disc 3- sulcate (as
Fig. 1H
), median sulcus and two curved paramedial sulci deep and punctate, two paralateral depressions conspicuous and punctate; lateral margin even in front and feebly crenulate behind, posterolateral angles rounded. Elytra punctate and moderately pubescent, but not rugose, without lateral longitudinal ridge.
Abdomen coriaceous and pubescent, broadest at segment V. Sternite VII (
Fig. 11E
) with posterior margin straight and with densely haired patch in middle. Sternite VIII (
Fig. 11F
) with subbasal ridge continuous and straight; posterior margin bi-emarginate near middle and lightly protruding in middle, apex weakly emarginate with carina behind. Tergite X (
Fig. 11H
) longer than wide, and anterior broader than posterior, with posterior margin bisinuate, with two lines of setae on haired posterior part.
Aedeagus (
Figs. 11K–N
). Median lobe elongated and broader basally, ventral edge of apical orifice with two small processes near middle and deeply emarginate in between, with sclerite-like or membranous structures in apical part of median lobe; apico-medial hook connected to body of median lobe by short scape, with apical tip triangular and sharply produced in middle behind tip, basal process well developed; dorsal membranous area covering most of apical part of dorsum and nearly across length of median lobe. Parameres arm-like, with apex flattened, enlarged and rounded, with ridge on ventral and lateral surface of each piece and screw-tracked apically, at near 1/2 of apical arm situated with long seta.
Female
. Head (
Fig. 11B
) smaller than male and always narrower than pronotum; clypeus subquadrate, anterior margin broadly rounded and protruding forward beyond anterior margin of supra-antennal ridges; vertex flat, but elevated compared to clypeus, posterior part well-limited and separated from neck by occipital suture; mid-longitudinal suture feeble nearly invisible, paralateral sutures absent; eyes convex, a little longer than temples; occipital suture with median portion present and obvious. Mandible (
Fig. 11D
) slender, sharply pointed at apex, but not so strongly curved as in male.
Abdominal sternite VII with posterior margin straight. Sternite VIII (
Fig. 11G
) with posterior margin broadly rounded, but protruding in middle. Tergite X (
Fig. 11I
) similar to male but posterior margin a little more protruding in middle.
Spermatheca (
Fig. 11J
) ʋ- shaped, basal portion slightly bulbous, apex rounded.

Remarks.
This species is different from the rest of the
Oxytelus
species
by its type II antenna and the head covered with more hairs and setae. When examining the type material from FMNH, we found that the
lectotype
(designated by P. M. Hammond) of
O. kalisi
Bernhauer, 1934
shows a high degree of resemblance to females
O. megaceros
. But this type of
O. kalisi
is a female specimen and we did not examine more type material, so we cannot reach any further conclusion.
