Description

Micranops bhamoensis, sp. nov.

(Figs 44–46)

Type specimen: Holotype ♂, Myanmar, Kachin: Bhamo, VIII.1885, leg. Fea (ISNB).

Description: Macrophthalmous species with palisade fringe of abdominal tergite VII; holotype macropterous with elytral sutural length about as long as pronotum and functionary metathoracic wings. Body color light brown; appendages light brown. Body surface subnitid with very fine, dense, setose punctation. Head 1.17 times longer than wide with moderately convex temples and straight posterior margin. Eyes 0.63 times as long as temples. Nuchal groove 0.23 times as wide as greatest head width. Trichobothrial cavity guttiform, with tapered anterior end connected to dorsoposterior margin of eye. Antenna from slightly elongate antennomeres 2 and 3 gradually wider toward transverse penultimate antennomeres; antennomere 10 about 0.7 times, antennomere 11 about 1.4 times as long as wide. Total body length 2.6 mm; forebody length 1.3 mm.

Male: Protarsomeres 1–4 dilated, approximately twice as wide as long.

Abdominal sternite VII without diagnostic characters.

Abdominal sternite VIII with subbasal ridge straight and posterior margin triangularly incised to approximately 0.2 of sternite length; lateral setae long, up to about 0.3 times as long as sternite length (cf. Fig. 155).

Aedeagus similar to that of preceding Micranops angkorensis (Figs 41–43), but ventral, membranous extension of apical lobes narrower, ventromedial endophallic lobe with shortly recurved apex and clearer proximal margin, and ventral process longer, in lateral view narrower, and with more strongly ventrad curved apical half (Fig. 44). Endophallic sclerites of holotype in evaginated state shaped as in Figs 44–46. Length of aedeagus 0.33 mm.

Female unknown.

Distribution: Micranops bhamoensis is only known from the type locality in northern Myanmar.

Etymology: The epithet bhamoensis [Latinized adjective (“from Bhamo”), derived from the locality name Bhamo with the Latin suffix - ensis that describes the geographical origin] refers to the type locality of this new species.
