description: Endomia graminicola sp. nov.
(Figs. 1, 4, 5)
Type locality. India, Maharashtra, Mulshi.
Type material. HOLOTYPE: ♁, ‘ INDIA, Maharashtra, ca 30 km W of Pune, MULSHI env., 18°29′N 73°30′E, ca 700 m, 13.-16.vi.2006, Z. Kejval lgt.’ (NMPC). PARATYPES: 11 ♁♁ 8 ♀♀, same data as holotype (ZKDC, 1 specimen each in BMNH, DCDC, HNHM, MHNG, MNHN, NHMB, NHMW, SMNS); 1♀, ‘ INDIA, Maharashtra Pune Distr., Mulshi at Mulshi lake, 8.X 2005 catch., leg. L. Borowiec // India Expedition 2005 Dept. of Biodiversity and Evol. Taxonomy Wrocław University’ (DBET).
Description (male, holotype). Head dark brown, with reddish/carmine tinge; pronotum rufous to reddish; elytra brown, with indication of darker transverse band in posterior half (Fig. 1); antennae rufous brown; legs and palpi yellowish.
Head 1.3 times as long as wide, somewhat widely rounded posteriorly; tempora subparallel, slightly narrowing towards base, posterior temporal angles rounded, moderately indicated; frontal protrusions small but distinctly protruding, frons flattened (not impressed); basal median carina less distinct, very slightly impressed in dorsal view. Eyes small, moderately convex. Surface less glossy, distinctly and rather densely punctured. Setation inconspicuous, very short, subdecumbent to apressed; setae rather narrow (not typically scale-like). Antennae strong, widened in terminal third (Fig. 4); basal antennomere thickened; antennomere 10 about 1.1 times, antennomere 11 1.5 times as long as wide.
Pronotum 1.4 times as long as wide, moderately narrower than head including eyes, evenly rounded anteriorly, at most slightly impressed postero-laterally in dorsal view. Surface less glossy; punctation and setation as on head.
Elytra twice as long as wide; humeri somewhat rounded but distinct; postscutellar impression absent. Surface moderately glossy, distinctly punctured; punctation somewhat sparser and coarser than on head. Setation similar to that on head, moderately longer.
Sternum VII simple. Segment IX forming thin, posteriorly bifurcate apodeme.
Aedeagus (Fig. 5); apical portion of tegmen 1.7 times as long as basal-piece, simple, nearly evenly narrowing towards moderately widened, triangular apex in ventral view.
Female. Externally identical with male.
Body length (♁ ♀). 1.7-2.0 mm (holotype 1.8 mm).
Variability. Elytra pale brown, with vaguely outlined but distinct brown-black transverse band to nearly unicoloured dark brown with reddish/carmine tinge (as head) and slightly paler apical fourth.
Differential diagnosis. Endomia graminicola sp. nov. can be easily recognized by its small size, slender body form, combined with strong antennae and very short, inconspicuous body setation. It differs from all known Oriental species in the form of tegmen, which is narrow with a slightly widened, triangular apex.
Etymology. Noun in apposition, composed from Latin gramineus (= gramineous, grass) and incola (= inhabitant); named in reference to the collecting circumstances.
Bionomics. Unknown. In Mulshi, the specimens were found on moist clay soil with sparse, mostly grazed grass in a small, flattened place among fields in an agricultural landscape. They were collected individually on the ground, together with specimens of Stenidius bezdeki Kejval, 2006, as I moved the plant debris near the grass tufts.
Distribution. India (Maharashtra).
