Andrahomanus luteipes Pic, 1903: 98   .

Type locality. Madagascar, Andrahomana.

Type material. HOLOTYPE, J ( Figs. 42 View Figs , 44 View Figs ): ‘ Madagascar (Sud) Andrahomana Alluaud 1900 39 [printed, only 39 handwritten in small frame in the right bottom corner] // MUSÉUM PARIS COLL. CH. ALLUAUD [printed] // TYPE [printed; red label] // Andrahomanus luteipes Pic   [handwritten]’ ( MNHN).  

Redescription (male, holotype). Body length 2.6 mm. Body brown with slight reddish tinge, elytra with paler suture and slight indication of paler transverse band in posterior half; antennae pale reddish; legs and palpi yellowish.

Head 1.2 times as long as wide, widely rounded posteriorly; posterior temporal angles rounded but distinct. Eyes small, moderately convex. Dorsal surface rather glossy, distinctly punctate, punctation simple, rather coarse, finer near basal margin. Setation short, subdecumbent; erect setae absent or at least indistinct. Antennae rather long, moderately enlarged in terminal third; antennomere X 1.14 times as long as wide, antennomere XI 1.7 times as long as wide.

Pronotum about as wide as long, distinctly wider than head including eyes; widely round- ed anteriorly, lateral sides moderately arcuate and narrowing towards base in dorsal view. Dorsal surface glossy, rather finely punctate; punctation finer than that on head, especially near base. Setation as that on head.

Elytra 1.6 times as long as wide, rather convex, conjointly rounded apically. Surface glossy, finely but distinctly punctate, basal punctation similar to that on head, only sparser, becoming finer towards elytral apices. Setation as that on head.

Metatibiae with inner apical margin produced into small, bluntly pointed projection ( Fig. 7 View Figs ); setation short and fine.

Abdominal sternum VII modified, with a pair of setose bulges, shallowly impressed between them medially, its posterior margin slightly sinuous ( Fig. 8 View Figs ). Tergum VII simple, with posterior margin slightly emarginate medially. Sternite VIII as in Fig. 9 View Figs ; paired prongs simple, moderately sinuous, narrowing towards pointed apex. Tergite VIII forming a narrow, arched sclerite, its posterior margin unevenly rounded in dorsal view ( Fig. 10 View Figs ). Segment IX as in Fig. 11 View Figs ; paired sclerites simple, with some longer setae apically.

Aedeagus as in Fig. 12 View Figs ; apical portion of tegmen 0.4 times as long as basal piece, with narrow, deeply incised and bifurcate apex; median lobe with membranous lobed apex, numerous mediad-pointing spinules and somewhat unclear sclerotized inner structure.

Differential diagnosis. Andrahomanus luteipes   can be easily recognized by the paler and generally rather glossy body, unique modifications of sternum VII and the metatibiae in males and the deeply incised apex of the tegmen.

Distribution. Madagascar.
