D e s c r i p t i o n: Small species, 2.0-
2.3 mm
(abdomen extended). Coloration: body reddish brown to brown, with abdominal segment
VI
and adjacent segments more or less extensively infuscate and sometimes also the head slightly darker; legs yellowish; antennae yellowish brown.
Facies as in
Fig. 98
. Head with very shallow microreticulation and some shine (
Fig. 99
); puncturation very fine and very sparse, barely noticeable. Eyes moderately small (
Fig. 100
), not distinctly projecting from lateral outline of head, approximately 0.35-0.4 times the length of postocular region in dorsal view.
Pronotum weakly transverse, approximately 1.1 times as wide as long and 1.15 times as wide as head (
Fig. 99
); microsculpture similar to that of head or slightly more pronounced; puncturation similar to that of head.
Elytra 0.50-0.55 times as long as pronotum (
Fig. 99
), without sexual dimorphism; microsculpture similar to that of head and pronotum; puncturation very fine, but slightly more distinct than that of head and pronotum.
Abdomen approximately 1.15 times as wide as elytra (
Fig. 98
), with distinct microsculpture, and with sparse fine puncturation; posterior margin of tergite
VII
with or without narrow rudiment of a palisade fringe.

: posterior margin of tergite VIII in the middle weakly concave (
Fig. 101
); posterior margin of sternite VIII obtusely angled in the middle (
Fig. 102
); median lobe of aedeagus with strongly reduced crista apicalis (
Fig. 103
); apical lobe of paramere as in
Fig. 104
.
: posterior margin of tergite VIII in the middle very weakly concave (
Fig. 105
); posterior margin of sternite VIII weakly convex and with row of numerous modified marginal seta, in the middle not distinctly concave (
Fig. 106
); spermatheca as in
Fig. 107.
E t y m o l o g y: The name (adj.) is derived from
Ordu
, the province where the
type
locality is situated.
C o m p a r a t i v e n o t e s: The geographically closest consubgeners are
G. euxina
PACE
and
G. macronorum
PACE
from the surroundings of Maçka in
Trabzon
. From both species,
G. orduica
is distinguished especially by the concave posterior margin of the male and female tergite VIII, the posteriorly obtusely angled male sternite VIII, the reduced crista apicalis of the median lobe of the aedeagus, the shape and
1212
chaetotaxy of the paramere, as well as by the shape of the spermatheca. From
G. euxina
, it is additionally separated by slightly larger eyes. For a supplement to the key in
ASSING (2005a)

G. soganlica
.

114
) apical lobe of paramere; (
115
) tergite VIII; (
116
) posterior margin of sternite VIII; (
117-118
) spermatheca. Scale bars: 108: 1.0 mm; 109: 0.5 mm; 110-112, 115-116: 0.2 mm; 113-114, 117-118: 0.1 mm.
D i s t r i b u t i o n a n d b i o n o m i c s: The
type
locality is situated in the mountains to the south of
Ordu
in
Ordu province
, northeastern
Anatolia
(
Map 8
). The specimens were collected by sifting the leaf litter and soil in a mixed forest with alder, spruce, bramble, and ivy at an altitude of almost
1000 m
.
