(mesotibiae). MTT1 shorter than MTT2+3 (Fig. 11b). MTT4 bilobate, its ventral face with two clusters of numerous unordered setae (Fig. 11c). Spermathecal duct as long as the spermatheca; duct of the spermathecal gland inserted at the tip of a small diverticulum ( Fig. 9e).

Description

Habitus . – Fig. 11a. Brachypterous. Body length: 11.4-13.1 mm.

Colour. – Head, pronotum and elytra black or piceous black, pronotum and elytra with a faint spectral iridescence; femora and tibiae dark brown, tarsi reddish-brown; antennomeres 1–3 reddish basally and dark brown distally, 4-11 testaceous; palpi reddish. Upper surface of the body smooth and shiny.

Microsculpture, mesh pattern. – Head:slightly transverse basally, more or less isodiametric near the anterior setae; pronotum:obsolete; elytra: obsolete.

Head. – Elongate, cychroid; frons flat, vertex convex. Eyes large, moderately convex; genae slightly convex. Frontal furrows shallow. Labrum apically bisinuate. Mandibles very long (as long as the head measured from collar constriction to clypeus apex), almost straight, briefly curvedand acute at apex.Lacinia and palpi thin and elongate. Mentum tooth simple, acute, with a well impressed marginal bead. Antennae relatively short, with a little more than two antennomeres extending backward beyond the base of the pronotum.

Prothorax. – Pronotum slightly transverse (PL/PW = 0.92); hind angles completely rounded; sides almost straight in basal third, arcuate at middle and in the apical third; anterior angles rounded, weakly protruding. Lateral margins broad, explanate and reflexed throughout; basal bead almost completely erased, apical bead obsolete medially. Laterobasal impressions deep. Two pairs of lateral setae; basolateral setae slightly anterior to angle. Sides of the prosternal process smooth, not bordered.

Meso- and metathorax. – Elytra oval-shaped, fusiform at apex; base narrow, basal bead strongly arcuate, humeri reduced and rounded. Subapical sinuation very shallow, elytral margin almost straight before apex. Striae thin, well impressed throughout, with very faint traces of punctation; intervals flat on most parts of the elytra, depressed near apex. Parascutellar setiferous pore present; third interval with 2 or 3 small setiferous punctures: the first at basal fifth or fourth (sometimes absent on one elytron or on both), the second just before the middle or at middle, the third just after the middle or at apical third. Umbilicate series of 18 to 20 setiferous punctures. Metathoracic wings vestigial, reduced to 2 mm long narrow strips.

Abdomen. – Last visible abdominal ventrite evenly rounded apically, with one pair ( ♂) or two pairs ( ♀) of setae along its apical margin.

Legs. –Robust, moderately long; metafemora without setae on the anterior ridge and with one ventroposterior seta. Dorsal face of protibiae vaguely depressed, of mesotibiae bluntly sulcate. Dorsal face of all tarsi convex, slightly squamose and bisulcate. MTT1 shorter than MTT2+3. Apex of PT4, MST4 and MTT4 bilobate; apical lobes of PT4 and MST4 with spatuliform hyaline phanera; apex of MTT4 asymmetrically bilobate, with a pair of hyaline ventroapical setae; ventral face of MTT4 with two clusters of numerous unordered setae (Fig. 11b-c). Fifth tarsomeres asetose ventrally.

Male genitalia. – Fig. 11d. Median lobe moderately curved, apex very short, acuminate. Endophallus without sclerotized structures.

Female genitalia. – Fig. 9e. Gonocoxite 2 elongate, with 2 ensiform setae on the outer ridge. Bursa copulatrix conical, glabrous, with a basal lobe on the right side. Spermathecal duct as long as the spermatheca; spermatheca rather big, vermiform; spermathecal gland with a long duct entering at the base of the spermatheca at the tip of a small diverticulum.

Habitat. – Montane cloud forest between 1300-2250 m a.s.l. This species has been found on the forest ground in rotten, fungusy logs or in rotting palm fronds, and also by fogging epiphytes on mossy branches.

Geographic distribution. – Western slope of the Cordillera Occidental in northern Ecuador ( Cotopaxi, Imbabura and Pichincha provinces).

Etymology. – This new species is dedicated to Hector Deysson (noun in apposition).
