Trechus indicus Putzeys, 1870:175. Holotype, lost (see Jeannel 1923, footnote p. 416). Type locality: eastern
India.
Trechus (s.str.) indicus Putzeys: Jeannel, 1927:157, 158 (in part)
Trechus (s.str.) macrops Jeannel, 1927:157, 160 (in part). Type locality: China, Yunnan. Synonymized by
Jeannel (1935: 275).
Trechus macrops Jeannel: Andrewes, 1935 63, 67.
Trechus indicus Putzeys: Jeannel, 1935:275.
Trechus indicus Putzeys: Deuve, 1988:80.
Trechus (s.str.) indicus Putzeys: Uéno 1977:181.
Trechus (s.str.) macrops Jeannel: Uéno & Yin, 1993:354. These authors considered T.macrops as a distinct
species.
DIAGNOSIS.— Adults of this species (Fig. 17a) can be distinguished from those of all other
species in the region by the following combination of character states: size large for genus (BL =
4.2 to 5.0 mm); fully-winged; eyes markedly large, tempora very short, joined to neck region at
nearly a right angle; frontal furrows angulate at midlength; right mandible as in Fig. 16b; mentum
and submentum not fused; mentum with medial tooth simple, triangular; antennae with antennomeres
3 and 4 subequal in length, antennomere 2 slightly shorter; pronotum transverse (ratio
Pw/PL = 1.43), with lateral margins not sinuate posteriorly, straight just anterior to basal angles,
the latter small and rectangular, lateral explanation very wide basally, basal margin slightly convex
medally; elytra oblong, lateral discal striae effaced, only the medial four or five striae distinctly
impressed, recurrent stria markedly impressed; preapical seta absent or vestigial, two discal setae
present, inserted in stria 3 at anterior one-fifth and at middle, respectively; median lobe of male
aedeagus (Fig. 17b) not arcuate, with apex slender, ventrally hooked, endophallus with two elongate,
projecting sclerites, one apically tapered, the other apically lobate.
COMMENTS.— Uéno (1977:182) correctly pointed out that this widely distributed species, with
members fully-winged, is morphologically varied across its range. In particular, the preapical seta
