Nototelmatoscopus (Jozifekia) laticoxa sp. nov.

( Figs 6 –12)

Type material. HOLOTYPE: J, THAILAND: CHIANG MAI PROVINCE: Doi Suthep-Pui National Park , 1 km above Doi Suthep Temple, small fast-flowing river, 18.805°N, 98.922°E, 11.iv.1991, sweep-net, T. Andersen leg. ( ZMBN).

Diagnostic characters. Eyes separated by 1 facet diameter at narrowest point, hypandrium present, aedeagus distally reaching further than apex of gonocoxites, basiphallus two-third the length of distiphallus, surstyli weakly pointed, apically with patch of 16 tenacula.

Description. Male (n = 1). Head (Fig. 7) round, about as broad as long; vertex rounded, one- -third of total head length; 3–4 dorsal ocular setae present, medial ones smaller; setae alveoli on vertex not covering posterior knob; eye bridge comprised of four rows of facets, separated medially by 1 facet diameter; interocular suture V-shaped with small medial swelling; patch of setae alveoli on frons semicircular, with narrow triangular extension posteriorly, extending to second facet row; frontoclypeal suture absent; clypeus transversely oblong with two rounded distal lobes, not projecting in front of eyes; palp with 4th segment corrugated, length of palp segments (in μm): 118, 207, 207, 278; mouthparts without special features.

Antennae with 16 segments; scape (Fig. 8) cylindrical, with apical triangular projection; pedicel globular with a distal sclerotized collar; flagellomeres slightly asymmetrical with ring of 14–17 circular ascoid insertion points; additional circular sensillum base present posterior to ring of ascoids; ascoids needle-shaped, reaching to basalmost hair row of next flagellomere; terminal flagellomere with digitiform setose apiculus which carries ring of 3 spines posterior to ascoid ring; length of antennal segments (in μm): 148, 78, 126, 118, 118, 118, 115, 118, 118, 111, 111, 107, 100, 96, 85, 104.

Thorax with dorsum, scutellum, anepimeron and laterotergite haired, other sclerites bare; prothoracal spiracle large, metathoracal spiracle with setose operculum; inner mesocoxal setose tubercle present; tibiae and tarsus 1 of all legs with sparse irregular rows of warts, tarsus 5 with apicodorsal projection; legs otherwise without special features.

Wing ( Fig. 6 ) 1.97 mm long, 0.73 mm wide; costa with single break; bases of both wings folded in specimen so basal venation characters not clearly visible; Sc with false vein of pigmentation present dorsal to R 1; base of R 2 weakened; medial fork slightly distad of radial fork, both basad to CuA

; jugum truncate.

Terminalia (Figs 9–12) with hypandrium present, hyaline, truncate with margins thicker; gonocoxite trapezoid with outer margins longest, inner margins medially with bulbous expansion; parameres trapezoid with margins sclerotized; gonocoxal condyles elongate and curved with small round medial sclerite; gonostyle slender, tubular, bent towards mesal side; distally with pair of sensilla; aedeagus with basiphallus narrow in dorsal view with origin of distiphallus expanded into a circular aperture, basal shape not discernable; distiphallus comprised of two elongate triangular lobes forming the margins of a membranous spatula, around 1.5 times as long as basiphallus; epandrium more than twice as broad as long, central aperture not discernable, distal corners with row of elongate setae and thickly sclerotized margins; surstyli (Fig. 11) about 1.5 times length of epandrium, subcylindrical with apex slightly pointed; inner margins with clearly defined ‘cercal area’ on mesal side reaching two thirds of total surstylus length; 16 tenacula present in irregular apicodorsal patch; apices of tenacula split (Fig. 12), longest tenaculum half-length of surstylus; proctiger with hypoproct tongue-shaped, epiproct oval, broader than long; both microsetose; hypoproct reaching one- -half the length of surstylus.

Etymology. From Latin latus, broad, and coxa, hip, referring to the broad gonocoxites. The epithet is to be treated as a noun in apposition.

Distribution and biology. Only known from the type locality in northern Thailand, where it was netted in vegetation along a small, fast-flowing river with rocky and stony substratum.
