Description of the new species
Description of the new species Pachynematus (Larinematus) tatricus spec. nov. (Roller & Haris) (Fig 26: a, b, c and d) Female: Length of body: 5.9 mm. Length of fore wing: 6.5 mm. Body black to dark brown with pale pattern (Fig. 26a and d). Head black; labrum, base of mandibles, labial and maxillary palps, distal parts of maxillae, labium and most of clypeus white to pale brown; proximal parts of maxillae and labium, apices of mandibles and 3 apical flagellomeres brown; flecks in ventral facial orbits, supraclypeal fleck, bilateral fleck on lower frontal ridges ocherous; two lateral flecks of postocellar area, vertex, most of temples and genae light ocherous; eye margins black lined. Thorax black; tegulae white; narrow posterior margin of pronotum whitish brown. Coxae, bases and inner parts of femora dark brown, rest of femora, trochanters, tibiae and tarsi whitish to light ocherous; tibiae and tarsi darkened apically, apices of hind tibia and hind tarsomeres 2-5 brown. Wings hyaline; venation brown; costa and subcosta white, subcosta brown lined, stigma white with brownish posterior margin. Abdomen dark brown; lateral part of tergites with somehow lighter patches. Sterna and terga with narrow whitish posterior margins. Cerci and basal part of sawsheath (valvifer 2) white; apical part of sawsheath (valvula 3) black with dorso-proximal ocherous patch. Body subshiny, with fine punctuation on head and thorax. Abdominal tergites with striated microsculpture. Densest punctuation forming coarse surface on facial part of head, vertex, temples, third antennái segment and pronotum. Thorax and head including paraantenal fields with short silver pubescence; hairs on vertex as long as two-third of ocellar diameter. Antenna slender, distally narrowed, as long as costa (without stigma) of fore wing. Approximate ratios of flagellomers (antennái segments 3-9): 1.0:1.6:1.5:1.2:1.0:0.9:0.8. POL: OOL: OCL: 1.8:1.7:1.0. Clypeus slightly emarginated. Frontal area concave with distinct frontal ridges. Frontal pit deep. Occipital carina absent. Malar space 1.3 times longer than diameter of front ocellus. Hind tibia with distinct longitudinal groove on outer side. Hind tarsus longer than hind tibia. Inner hind tibial spur short, as long as apical breadth of hind tibia. Tarsal claws with small, erect inner tooth distant from apical tooth. Width of subcostal cell at the point of origin of radial sector + medial vein is almost as wide as apex of swollen costa. Abdomen laterally compressed with blunt medial longitudinal ridge on terga 3-8. Cerci reach apex of short sawsheath. Sawsheath as long as two-third of hind tibia, subparallelsided with truncated apex in dorsal view. Apical setae of sawsheath slightly curved, half as long as cercus (Fig. 26c). Sawsheath in lateral view with blunt apical truncation as long as dorsal margin of sawsheath (Fig. 26b). Lancet (valvula 1) without distinguishable teeth. Lamnium shorter than radix, subdivided into 15 annuli with distinct ctenidia. Holotype: female, 15 May 2007, Tatranská Lomnica - Start, leg. O. Majzlan, MT2007. Deposited in the Slovak National Museum - Natural Science Museum in Bratislava. Code MT 2007: coll. Malaise trap, altitude 1 150 m, the trap was exposed in the clearing of montane spruce forest Larici-Piceetum (Fig. 27). Etymology: The specific name is an adjective, derived from the name of mountains where the holotype was collected. Tatry is the highest mountain range in the Carpathians (Slovak Tatry, Hungarian Tatra and English the Tatras).
