Diagnosis
Leptochirus (T.) mery sp. nov., L. (T.) yunganus and L. (T.) zischkaianus have the median sulcus of head gradually narrowing anteriorly ( Figure 2C, H, I View Figure 2 ). L. (T.) mery sp. nov. can be distinguished from L. (T.) yunganus and L. (T.) zischkaianus by the first dorsal tooth of the left mandible not bifurcate ( Figure 3C View Figure 3 ).
Description
BL: 12.48, BW: 2.06
Body strongly depressed. Body all black except tarsi red-brown.
Head. Transverse ( Figure 2C View Figure 2 ). Inner lateral teeth separated by a depression extending to base. Inner and outer lateral teeth fused and resembling a septum; median sulcus deep, gradually narrowing anteriorly; laterofrontal depressions oval. Labrum with outer edge strongly angled and lateral-apical edge concave. Mandibles ( Figures 2C View Figure 2 , 3C View Figure 3 ) with lateral longitudinal ridge occupying less than two-thirds of apical region; external margin developed, attenuated anteriorly. Left mandible ( Figure 3C View Figure 3 ) with first dorsal tooth developed, straight and not bifurcate, accessory tooth near lateral longitudinal ridge; second dorsal tooth little developed and resembling a small hill; first ventral tooth with tooth accessory, third ventral tooth consisting of two structures not fused at the base. Submentum with setae arranged in row on the anterolateral margin.
Thorax. Pronotum ( Figure 2C View Figure 2 ) a little wider than long (PL: 2.21, LP: 2.42); superior marginal line of hypomeron not interrupted, not bent to dorsal region at anterior margin and slightly bent to region at posterior margin; without a pair of small depressions near basal constriction. Inferior marginal line of hypomeron reaching anterior margin. Apex of prosternal process strongly expanded and resembling a circular plate, extending considerably beyond the lateral process of hypomeron. Metaventrite with microsculpture longitudinally undulate in median region and without small longitudinal median depression near posterior edge. Mesoscutellum with apex rounded. Elytra longer than broad and without pair of small depressions on posterior-lateral edge (EL: 2.67, EW: 2.21).
Abdomen. Cylindrical. Sternite III with keel of apex rounded. Tergite IX ( Figure 4P) sclerotized with left and right plates separated, each with five or six setae of various lengths. Tergite X ( Figure 4P) membranous except for sclerotized apical part, with two pairs of long apical setae.
Male. Sternite IX ( Figure 4Q) composed of two plates, distal plate sclerotized, anterior margin slightly projecting, posterior margin with small acute projection in the middle and with two long setae; proximal plate less sclerotized, greater than apical, broadened in middle and with angle at posterior border not projecting. Aedeagus ( Figure 4M–O) with median lobe slightly bulbous at base, almost straight at apex, weakly sclerotized on dorsal side and a small plate sclerotized on ventral side; parameres short, pointed and fused dorsally.
Female. Similar to male, except for the gonocoxites divided longitudinally ( Figure 4R). The distal plate with apex membranous and long seta; proximal plate with the posterior region rounded.
Distribution
Leptochirus (T.) mery sp. nov. is currently known from Ecuador and Bolivia ( Figure 7 View Figure 7 ).
Biological notes
This species has been found in fallen leaves.
Etymology
The specific name “mery” is in honour of my sister Mery Asenjo . This is a noun in apposition, gender feminine.
