Etymology.

Latin, clavata, meaning clavate; referring to the club-like surstylus; a feminine adjective.

Diagnosis.

Antenna yellow with 1st flagellomere brown on apical 2/3; arista plumose, with longest rays slightly shorter than height of 1st flagellomere. Mesonotum 0+3 dc, anterior dc weak, hair-like; acr in 6 rows. All tibiae black with pale yellow at base; fore tarsi black, mid and hind tarsi dark yellow. Mid femur with 5 a.

Description.

MALE. Body length 2.9-3.7 mm, wing length 3.2-3.8 mm. FEMALE. Body length 3.0-3.3 mm, wing length 3.3-3.7 mm.

Head. Face slightly shining. Frons with yellow anterior margin. Gena about 1/6 eye height. Antenna yellow with brown on apical 2/3 of 1st flagellomere, 1st flagellomere nearly 1.7 times longer than high; arista plumose, with longest rays slightly shorter than height of 1st flagellomere. A blackish brown rectangular spot present between eye and base of antenna. Proboscis and palpus black.

Thorax with brownish gray pruinosity. Mesonotum 0+3 dc (anterior dc weak, hair-like, far behind transverse scutal suture), acr in 6 rows; prsc longer than 1st post-sutural dc; anepisternum with setulae on lower margin. Legs: all tibiae black with pale yellow at base; fore tarsi black, mid and hind tarsi dark yellow. Fore femur with 4 pv and 6 pd, fore tibia with 1 short preapical ad and 1 short apv. Mid femur with 5 a and 1 app; mid tibia with 1 strong preapical ad and 1 strong apv. Hind tibia with 1 weak preapical ad and 1 short apv. Wing with costa with 2nd (between R1 and R2+3), 3rd (between R2+3 and R4+5) and 4th (between R4+5 and M1) sections in proportion of 4:1.7:1; r-m at middle of discal cell; ultimate and penultimate sections of M1 in proportion of 1:1.1; ultimate section of CuA1 about 1/5 of penultimate section.

Abdomen shining. Male genitalia (Figs 11-15): syntergosternite circular with an inner tooth near spiracle, epandrium nearly rectangular; surstylus fused with epandrium, clavate with a triangular basal process, a projecting apical process, a small acute ventroapical process and a tiny incision in lateral view; hypandrium nearly U-shaped, hypandrial apodeme distinct; postgonite slender, broad apically in lateral view; aedeagus columnar and rounded apically, with a slight incision; aedeagal apodeme long, slightly shorter than aedeagus. Female terminalia (Figs 35-36): sternite 7 trapeziform, furcating apically with long setae; sternite 8 pale yellow, nearly columnar with a small apical incision; spermathecae 2+1, round.

Remarks.

The new species is very similar to Minettia (Minettiella) plurifurcata sp. n. (see discussion under Minettia (Minettiella) plurifurcata sp. n.) from China (Hubei). This new species is also similar to Minettia (Minettiella) atrata from Indonesia (Java) in having the arista short plumose and the mesonotum with acr 6 rows, and without other strong acr in front of strong prsc, but it can be separated from the latter by the mid and hind tarsi being yellow. In Minettia (Minettiella) atrata , only the hind tarsi are yellow ( Meijere 1910; Malloch 1929).

Distribution.

China (Hubei).
