Astenus nigromaculatus
(MOTSCHULSKY
,
1858)
M a t e r i a l e x a m i n e d:
Israel
: 1, Ma'agar Yeroham,
450 m
, pitfall,
30°59'N

,

, leg. Drees (cAss).
C o m m e n t: According to
SMETANA (2004)
, this species is widespread in the Mediterranean region, but was previously unknown from
Israel
.

C o m m e n t: The original description of
A. platynotus
is based on "Un seul mâle, trouvé a Naplouse [= Nablus]" (
SAULCY 1865b
). According to the curator in charge at the MNHNP, where the Saulcy collection is housed (
HORN et al. 1990
), a careful search for the
holotype
proved unsuccessful; it yielded only four non-type specimens in the Jarrige collection (TAGHAVIAN e-mail 27 May, 2014). Thus, like many other types of species described by Saulcy, the
holotype
of
A. platynotus
is most likely lost. This species belongs to a group of very similar, possibly myrmecophilous species, at least three of which are represented in
Israel
. In the interest of the stability of nomenclature, therefore, one of the
four males
from Nablus in the Jarrige collection is designated as the
neotype
. The specimen is in agreement with the original description and was collected only some
50 km
from the original type locality of
A. platynotus
.
R e d e s c r i p t i o n: Body length
3.6-4.8 mm
; length of forebody 2.0-
2.5 mm
. Habitus as in
Fig. 1
. Coloration: body black, with the posterior margins of the elytra occasionally indistinctly and narrowly paler; legs dark-yellowish; antennae reddish.
Head (
Fig. 2
) 1.15-1.20 times as broad as long; posterior margin strongly concave; punctation shallow, very dense, and umbilicate; interstices reduced to narrow ridges. Eyes approximately as long as postocular region. Antenna (
Fig. 3
)
1.1-1.2 mm
long; antennomeres IV-X of distinctly conical shape and very weakly oblong.
Pronotum (
Fig. 2
) approximately as broad as long and 0.9 times as broad as head, laterally or antero-laterally usually with a very shallow impression on either side; lateral margins straight to weakly convex in dorsal view, distinctly converging posteriad; anterior and posterior angles each with a long black seta (often broken off) of approximately half the length of lateral margin; posterior margin convexly produced in the middle; punctation similar to that of head.
Elytra (
Fig. 2
) 0.62-0.66 times as long as pronotum; humeral angles moderately marked; punctation distinctly granulose; interstices glossy. Hind wings completely reduced.
Abdomen 1.00-1.10 times as broad as elytra; punctation very dense on anterior tergites, gradually decreasing in density from tergite III to tergite VIII, moderately dense on tergites VII and VIII; posterior margin of tergite VII with narrow rudiment of a palisade fringe.
: sternite VIII shaped as in
Fig. 4
; aedeagus approximately
0.7 mm
long, shaped as in
Figs 5-9.
D i s t r i b u t i o n a n d n a t u r a l h i s t o r y The confirmed distribution is confined to
Israel
and
West Bank
. The species has been reported also from
Lebanon
(
SMETANA 2004
), but this record requires revision. The external morphology (broad body; short antennae) suggests that
A. platynotus
may be associated with ants of the genus
Tetramorium
MAYR, 1855.
