Figs 7A, 8–9

Diagnosis

Femotyche hortorum sp. nov. can be easily separated from the other species of the genus, F. kerryae sp. nov., by a longer head with vertex 3.53 times as long as wide in midline (Fig. 8G) (2.64 in F. kerryae – Fig. 1G); the pygofer in lateral view with a moderate and slightly curved ventrad posterior process (Fig. 9A) (posterior process of pygofer strong, tusk-like and upcurved in F. kerryae – Fig. 3A); and the sides of the adeagus in dorsal view strongly sinuate (Fig. 9J) (regularly curved in F. kerryae – Fig. 3I).

Etymology

The species epithet is a patronym dedicated to Fred and Jean Hort (Perth, WA), who collected the type specimen and provided information and photographs of several Cleotychini from Western Australia.

Description

Measurements and ratios

LT: ♂ (n = 1): 4.63 mm. LTg/BTg = 1.59; LV/BV = 3.53; LF/BF = 4.87; LPf/BPf = 3.88; LPt/BPt = 2.70.

COLOUR (Fig. 8A–E). Pale yellowish grey dorsally including frons, lateral lobes of pronotum, abdominal sternites, and meso- and metatibiae and tarsi; clypeus, all coxae and femora and protibiae black or blackish brown; protarsi white with black claws.

HEAD (Fig. 8G–I). Vertex very narrow, about 3.5 times as long as wide, strongly projecting beyond eyes, nearly twice as long as eye in midline, in dorsal view, roundly pointed anteriorly, with weak median carina and with lateral margins carinate; posterior margin not carinate, angularly incurved. Frons narrow, about 4.9 times as long as wide, weakly sinuate in lateral view; sides subparallel, constricted at level of eyes, anteriorly roundly pointed in perpendicular view, with median and lateral carinae (along lateral margin) extending to apex of clypeus; intermediate, incomplete, longitudinal carinae from margin of cephalic process, reaching to level of anterior margin of eye. Clypeus elongate and narrow, triangular, tricarinate. Eyes rather large, moderately protruding laterally. Antennae with scape short and cylindrical; pedicel short, inflated, barrel-shaped and with large sensory plates on ventral portion. Labium elongate and narrow, reaching posterior trochanters and with apical segment elongate, about half as long as penultimate one.

THORAX (Fig. 8G–I). Pronotum about 2.5 times as wide as long in midline, smooth with anterior margin strongly bisinuate, roundly projecting anteriorly behind vertex and roundly emarginate behind eyes, and posterior margin weakly incurved; median longitudinal carina and two lateral carinae on disc merging anteriorly along anterior margin; paranotal lobe rounded posteroventrally. Mesonotum short, about 2.3 times as wide as long in midline and slightly longer than pronotum, smooth with three hardly visible obsolete carinae prolongating pronotal ones. Tegulae absent.

TEGMINA (Fig. 8G, I). Brachypterous; tegmina slightly elongate in dorsal view, about 1.6 times as long as broad, sides broadly rounded in dorsal view, slightly broadening from base to apex, broadly, roundly truncate apically, convex, smooth; no trace of venation.

LEGS (Fig. 8A–F). Profemora elongate, moderately foliaceous, about 4.0 times as long as wide, with ventroapical strong tooth; protibiae elongate, foliaceous, about 2.5 times as long as wide; median legs elongate and slender, much shorter than anterior legs,with mesotibiae slightly more slender than mesofemora; posterior legs elongate and slender; metatibiae broadening towards apex, with two lateral spines, one near tibiofemoral joint and one in distal half of tibia, and six apical spines; first and second metatarsomeres with strong spine at each side and apical row of 12 platellae ventrally. Metatibiotarsal formula: (2) 6/2/2.

ABDOMEN (Fig. 8 A–E). Dorsoventrally flattened and smooth, largely visible in dorsal view.

Male terminalia (Fig. 9)

Pygofer (Py – Fig. 9A–E) moderately curved in lateral view, with anterior margin strongly bisinuate in lateral view and with strong process projecting posterad and weakly curved ventrad on posterior margin; pyfoger suboval in posterior view. Gonostyli (G – Fig. 9A–E) moderately developed, elongate and tapering towards the posterior in ventral view; dorsal margin with strongly recurved lateral hook (lh) directed mesoventrad and pointed,curved dorsal process (dpg) directed cephalodorsad.Aedeagus(ae – Fig.9F–K) moderately elongate, dorsoventrally flattened and rather wide in dorsal view, with strongly sinuate laterodorsal processes (ldp) of phallobase (phb) in lateral view; in dorsal view, laterodorsal processes roundly projecting laterocephalad in a strong lamina, with lateral margin strongly bisinuate towards the posterior; distal portion strongly tapering, twisted and curved posteroventrad but with dorsal margin weakly upcurved, with lateral margin slightly lamellate laterally and bearing numerous pointed teeth directed caudad; connective (cv) moderate, with well-developed, laterally flattened suboval tectiductus (td). Anal tube (An – Fig. 9A–E) massive, curved and widening towards the posterior in lateral view and with large, pointed, triangular lateroventral tooth (alt) in distal portion projecting ventrad; in lateral view, ventral margin sinuate in basal portion, and forming a nearly right angle at base of tooth; in dorsal view, about 1.02 times as long as broad in midline; broadest at ⅖ of length; lateral margins forming an angularly rounded lobe in basal half in dorsal view.

Biology

The species was recorded in the month of January and its biology remains unknown.
