Limentinus declinatus sp. nov.

( Figs 7, 9, 11 , 29–36 )

Description. Measurements. Male body length 7.44 mm; head width 1.81 mm; crown length×width 0.71× 0.72 mm; eye width 0.65 mm; frontoclypeus length 1.61 mm, clypellus length 0.64 mm; pronotum length×width 0.72× 2.20 mm; mesonotum+scutellum length 1.10 mm. Female unknown.

Crown pale with longitudinal black band on each side of midline ( Fig. 7 ) continued onto face and eXtended to apeX of clypellus ( Fig. 9 ). Forewings with faintly continuous patches basally and ochraceous spots distally, costal margin with semicircular translucent area just distad of midlength ( Fig. 11 ). Legs pale. Ratio of crown, pronotum and mesonotum midline about 1:1:1.55.

Male genitalia. Pygofer large with caudoventral and caudodorsal processes very small ( Figs 29, 30 ). Segment X broad, lateral margins parallel ( Fig. 30 ). Aedeagus tubular, apical third with three seta-like long spines on left ( Fig. 31 ), 4 long spines on the lower right side ( Fig. 31 ); apeX hook-like in lateral view ( Fig. 33 ), with 4 and 1 short spines on each side separately ( Fig. 32 ). Gonopore dorsal in apical third ( Fig. 32 ). Dorsal connective stick-like ( Fig. 33 ). Style short, eXtended about to middle of aedeagus, apophysis with lateral margins parallel, apeX truncate ( Fig. 35 ). Connective nearly triangular, anterior stem equal to arms in length ( Fig. 34 ). Subgenital plate slender, apeX rounded with sparse setae ( Fig. 36 ).

Material examined. Holotype: male, Madagascar: Haute Matsiatra Region, ANJA Reserve , 61km S Ambatavoa, 13km S of Fianarantsoa, 1097m, 23°43.23′S, 46°15.47′E, 10–17 Jan 2013, coll. M. Irwin, R. Harin Hala.

Etymology. The new species name is a Latin word referring to the arrangement of asymmetrical spines at apeX of the aedeagus.

Remarks. This species is similar to L. aldabranus Distant but can be differed by pygofer with caudoventral processes, aedeagus with 5 short spines apically and tuft of long processes laterally on each side of shaft, the latter species without caudoventral pygofer processes, aedeagus with one short spine apically and several long processes on apical third of shaft.
